When the value reached, pulse blowing is carried out by the program control regularly when the dust adsorbed on the outer surface of the filter bag is reached. That is, the high-pressure air is sprayed to the Changwen tube, and the purified gas is blown back into the filter bag to form a large pressure difference, and the dust is cleaned down to achieve the purpose of cleaning the dust, and the resistance of the whole equipment and system is kept stable, The dust from the back blowing falls to the bottom of the lower box and is discharged and recycled by the screw conveyor.

مبدأ عمل مجمع الغبار في مصنع الأسمنت:

The special dust collector of cement plant ionizes the flue gas by high voltage electric field, and the charged dust in the air flow is separated from the air flow by the electric field. Negative is made of metal wires with different cross-section shapes, which is called discharge electricity. It is made of metal plates with different geometric shapes, which is called dust collector. The performance of dust catcher in cement plant is affected by three factors: dust property, equipment structure and flue gas velocity.

The dust catcher of cement plant will also cause excessive discharge due to the damage of filter bag. The dust collectors in the cement plant are more than 10 bag rooms. It takes 5 ~ 30 minutes to determine the location of the broken bag from the discovery of excessive discharge. At present, the service life of dust removal filter bag is more than one year, and the broken filter bag only occurs after one year. If it is found out that the damaged filter bag is located in the bag room, as long as the bag room is closed and replaced, other bag rooms can still operate normally. Generally, closing 20% bag chamber will not affect the production of process equipment and the dust removal efficiency of dust removal facilities. Timely detection of filter bag damage is the key to reduce excessive emissions, which can only rely on the timely alarm of online continuous detection equipment. It is generally believed that if the bag filter is broken, it can be found when a small part of the bag filter is damaged, and other filter bags will also play a role. The excessive emission is far less than that of the electrostatic precipitator when CO exceeds the standard.

The dust remover on the top of cement bin is a kind of single dust removal equipment with automatic ash cleaning structure. This kind of dust remover is widely used in the fine, non fibrous dry dust in the filter gas or a dust removal equipment for recovering dry powder in the process flow in cement, mineral powder, mining, metallurgy, building materials, machinery, chemical industry, grain processing and other industrial and mining enterprises.

مبدأ العمل لمجمع الغبار أعلى صومعة الأسمنت:

The dust filter of the dust collector on the top of the bin is carried out through the filter element. The filter element material is glass fiber. When the dust containing air passes through, the solid phase can be used to separate from the gas phase. The filter element of glass fiber is a porous dust filter material. When the air flow passes through, the particles in the air flow can be absorbed on the filter element or settled down due to vibration and the purified air can be discharged, In order to attach and sink the dust into the filter element, the dust collector shall be vibrated in sequence when the fan of each shift is stopped (every 2-4 hours), and the dust collector shall be vibrated for about 5 times.

The main structure design of dust collector on the top of cement silo is the spatial frame structure set by beam element. Therefore, all kinds of loads to be investigated can be simplified to equivalent joint force acting on the beam element node. Because the nature of beam element determines, each beam can be treated as a unit and some secondary beams can be deleted, The calculation amount of the corresponding stiffness and load will be reduced greatly when added to the main beam. The finite element model given here is shown in figure 10-. But it is pointed out that the displacement mode of finite element beam is actually given according to the formula of straight beam in material mechanics. Under the assumption of material mechanics, the internal force and displacement of two ends of the beam are obtained by finite element analysis. Meanwhile, its deformation form is half wave, which is obviously not enough for the analysis of non-random, which is because if a beam is a unit, The instability critical load of beam half wave can only be given by the finite element analysis of its structure, which may lead to the progress of the critical load of the structure and the structural analysis. Therefore, this problem is noticed when modeling the main structure of ESP. The solution is simple. Only some elements (generally one beam is divided into more than 3 elements) are required for some possible stable main beams. In the analysis of non-random, it is necessary to avoid only allowing the half wave instability of the fixed European tie rod at both ends to rise, thus increasing the reliability of the calculation results.

It is used in silicon iron furnace, industrial electric furnace and low operating cost. It is an ideal equipment for flue gas dust removal of domestic dryers.

The dryer dust collector is a dust collector specially used to deal with the exhaust gas of the dryer. The dryer is based on the front hot air stove drum into the hot air to carry on the rolling drying of the material. Because the hot air stove in front of the dryer adopts the coal-fired method, the exhaust gas produced contains a large amount of SO2 and water vapor, which is easy to condensation and produce strong corrosiveness. Under the condition of high temperature and oxygen enrichment, it is also easy to generate H2SO3 with strong corrosiveness. Therefore, the waste gas treatment of the dryer is a serious problem which is a serious problem for production. The above characteristics of exhaust gas should be paid attention to when dealing with such gases. In view of this working condition, our company has carried out special treatment on the dust collector. The flower plate made of ordinary 325 steel plate is replaced with stainless steel. The filter bag is selected, the treated filter bag is fluorous, and the skeleton is made of silicone (or stainless steel). The dust collector is treated with three layers of epoxy polyester anticorrosive coating. The outer layer is insulated with 10 cm thick light rock wool and color steel plate. After the above improvement, the dust collector can meet the working conditions of the dryer.

تطبيق مزيل الغبار بالمجفف:

Under the normal condition of ash cleaning, the remaining ash layer remains stable, that is, the resistance is basically the same before and after ash cleaning, which overcomes the phenomenon of resistance accumulation with the increase of operation time. This kind of wind stopping and shock vibration beating is the combination of optimization of ash cleaning method, so it has high strength ash cleaning effect. The weight of the remaining ash layer is 10-20 times more than that of the average settlement in one filter period; However, the weight of the remaining ash layer is less than one third of the average deposition of a filter cycle, and it is only twice as much as that of the glass fiber flat bag.

Wood--Dust removal equipment for woodworking industry

1.Central woodworking dust removal system

The principle of woodworking dust removal system is to save investment as much as possible. Due to the high concentration of dust produced by woodworking equipment in the process of processing, the commonly used explosion-proof pulse bag dust removal technology in China is adopted to achieve the purpose of dust recovery and waste gas purification, so that all emission indicators meet the emission requirements.

There are two important technical and economic indexes of woodworking dust removal system: one is investment cost, the other is operation cost. The former is disposable, while the latter is regular, and its cumulative number can be several times or even tens of times of the former. In the operation cost, the proportion of power consumption and vulnerable parts is large. Therefore, reasonable design is very important to reduce the operation cost. In the design of this dust removal process, we are more innovative than other similar equipment in the following aspects;

1. In the connection between the air outlet of the dust collector and the fan, we design a soft connection to eliminate the vibration caused by the high-speed operation of the fan; A muffler is designed at the outlet of the fan to reduce the noise caused by the high-speed operation of the fan;

2. In order to facilitate the maintenance and observation of the dust collector, we have designed a plexiglass observation (maintenance) door at the lower part of the dust hopper of the dust collector; The pipeline of the system is connected by flange between 4-6m, and the access door is designed about 5m; It is convenient to observe and clean the dust deposition in the pipeline;

3. According to the hydrophilic characteristics of wood dust, the dust is easy to agglomerate under some moisture content, and arch into a bridge in the dust hopper of the dust catcher, which leads to material blockage. We have designed a vibrator in the dust hopper of the dust catcher to assist in dust cleaning and reduce the manual auxiliary dust cleaning work;

4. The electrical control of dust removal system, ventilation and dust removal system need matching fan and air compressor, the drive needs three-phase four wire power supply, dust removal of dust collector should be equipped with a pulse controller, the pulse controller is installed near the dust collector, the power supply of control cabinet (box) is provided by the construction party, the cable is required to be pulled to the main switch pile in the control cabinet, at the same time, please provide public grounding, Convenient ground connection.

5. In view of the characteristics of high concentration of wood dust, we adopt the design of gradual airflow channel to ensure the uniform distribution of airflow. The air distribution is optimized to avoid high-speed scouring and abrasion of the local area inside the dust collector, so that all filter bags can be evenly injected and filtered by the compressed air, and the overall life of the filter bag can be improved.

 

 

2.Woodworking cyclone

The woodworking cyclone dust collector is mainly composed of ash hopper, filter chamber, clean air chamber, support, lifting valve, injection cleaning device, etc. When working, the dusty gas enters the ash hopper through the air duct. Large particles of dust directly fall into the bottom of the ash hopper, small particles of dust with the air flow turning upward into the filter chamber, and are blocked in the outer surface of the filter bag, purified flue gas into the bag, and through the bag mouth and the clean air chamber into the air outlet, and discharged by the exhaust outlet.

The structure of woodworking cyclone is simple, compact and the consumption of steel is low. Compared with the heavy and light fibrous dust, such as sawdust, shavings, asbestos powder, tobacco and so on, it has higher collection capacity.

In order to meet the more and more strict requirements of labor protection, environmental protection and product processing accuracy, woodworking manufacturing enterprises deal with the dust generated in the production process. A large number of micro dust and sawdust generated in the production process of woodworking industry will not only adhere to the surface of equipment and workpiece, affect the processing quality, cause workpiece scrap or frequent equipment failure, but also pollute the working environment, leading to silicosis. Therefore, the workshop ventilation, timely discharge of dust, and the dust air purification, in order to keep the equipment and workpiece surface clean.

The principle of woodworking cyclone dust collector: the woodworking cyclone dust collector has the characteristics of novel structure, small size, large air volume, light weight and high separation efficiency, with the separation efficiency up to 99.5% for the dust laden air flow containing wood blocks and other mixed debris, and small resistance. The structure of woodworking cyclone is simple, compact and the consumption of steel is low. Compared with the heavy and light fibrous dust, such as sawdust, shavings, asbestos powder, tobacco and so on, it has higher collection capacity.

Technical features of woodworking cyclone dust collector:

1. High dust removal efficiency. For the gas with dust mass liquid concentration less than 10 ISO / m3, the dust removal efficiency can reach 99.99%, which can adapt to continuous and high liquid concentration dust (the inlet mass liquid concentration can reach 60 ISO / m3).

2. Lower pressure air intake preset to overcome secondary dust. Proper treatment of super dust and low-density dust environment, coupled with excellent performance of filter material, can make the dust collector stable operation; Compared with the traditional bag filter, the energy consumption is reduced by 30%, and the equipment can operate stably.

3. Filter material net surface horizontal plug-in structure, horizontal change bag, meet the indoor installation of low floor; Compact structure, 30% less space than traditional products; Due to the adoption of reliable pulse spraying ash cleaning, the filtering wind speed of filter material in the same application environment is more than three times higher than that of reverse blowing ash cleaning method, so as to greatly reduce the filter material area and avoid the situation of complex equipment, large investment and large floor area.

4. The key mechanical and electrical components of the equipment are imported from Australia. For example, pulse instrument and program controller can work more than one million times to ensure the stable operation of dust removal system; The resistance of the dust collector is reduced by 20-30% compared with other essentials by using the filter material with good air permeability and anti sticking and moisture-proof treatment. Under normal use, the service life of the dust collector can reach more than 3 years.

 

 

 

3.Dust collector in woodworking workshop

The dust remover in woodworking workshop has the characteristics of small resistance, high dust removal efficiency, large air volume, stable performance, simple structure and low cost. After the dust gas enters from the upper air inlet of the ash hopper, the air flow moves towards the wind shield, and the flow rate decreases. Some large particles of dust are separated into the ash hopper due to the effect of inertia force. The dust containing gas enters the middle box and is filtered and purified by the filter bag. The dust is blocked on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag mouth and is discharged by the air outlet.

The design concept of dust remover in woodworking workshop is based on the principle of saving investment as much as possible. Because of the high dust concentration produced by woodworking equipment during processing, the pulse bag dust removal technology commonly used in China is adopted to recover dust and purify waste gas, so that all emission indicators meet the emission requirements.

The dust remover in woodworking workshop is suitable for all kinds of woodworking machinery equipment such as four sides planer, sanding machine, sawing machine, slicing machine, rod mill, etc. the method of single machine dust removal or system dust removal can be used. Single machine dust removal is mainly used for dust removal of single woodworking machinery, which has the characteristics of flexibility and convenience. The system dust removal is used in the dust removal of woodworking machinery production line, which has the characteristics of economy, practicality and aesthetics, which does not affect the production operation, but also achieves the ideal dust removal effect. Bag filter is a high efficiency dust collector, and the dust removal effect can reach 99%. It is suitable for collecting dust of solid wood particleboard, artificial board particles and fiber. The pulse bag filter of air box uses filtration method to keep dust particles in dust containing gas on fabric of fabric fabric, so as to purify the gas. Compared with the general dust collector, the dust removal efficiency can be more than 99%, and the particles about 1 micron can be removed. The dust collector has the advantages of simple structure, low investment cost, simple operation, reliable management and maintenance technology.

In order to meet the requirements of more and more strict labor protection, environmental protection and product processing accuracy, woodworking manufacturing enterprises deal with the dust produced in the production process. A large number of micro dust and sawdust generated in the production process of woodworking industry will not only adhere to the surface of equipment and workpiece, affect the processing quality, cause workpiece scrap or frequent equipment failure, but also pollute the working environment, leading to silicosis. Therefore, the workshop ventilation, timely discharge of dust, and the dust air purification, in order to keep the equipment and workpiece surface clean.

 

 

4.Woodworking bag filter

Woodworking bag dust collector adopts the way of dust collection and treatment, which can purify and collect the dust generated by woodworking machinery operation. It is divided into two types: internal filter type and external filter type, usually according to different filtering methods. In order to avoid the direct impact of dust on the bag, the woodworking bag dust collector optimizes the air inlet system, adds the baffle plate, splitter plate and swirl plate, prolongs the service life of the bag, which is your choice.

Woodworking bag filter is an important part of: woodworking dust without three devices, piping system, fan system, filtration system. In these three systems, the structures and functions of different configurations are different, but the basic principles are the same, just like people wearing masks. The pipeline is connected with woodworking machinery and filtration system, and the fan works to generate negative pressure dust. The main ones are the configuration of fans and the performance of filter bags. The fan configuration is calculated according to the number of machines in the production workshop and the arrangement of machines, which requires the personnel to calculate the configuration, so that the air volume of the filter interface of each machine can reach the same, and then the dust can be removed effectively. Dust filter bag should be selected according to different environment, and the nature of dust produced in different woodworking workshops is different.

Working principle of woodworking bag dust collector: the woodworking bag dust collector is mainly composed of ash hopper, filter chamber, clean air chamber, support, lifting valve, injection cleaning device, etc. When working, the dusty gas enters the ash hopper through the air duct. Large particles of dust directly fall into the bottom of the ash hopper, small particles of dust with the air flow turning upward into the filter chamber, and are blocked in the outer surface of the filter bag, purified flue gas into the bag, and through the bag mouth and the clean air chamber into the air outlet, and discharged by the exhaust outlet. With the continuous filtration, the dust on the outer surface of the filter bag increases, and the resistance of the equipment increases. When the resistance of the equipment rises to the maximum value, the ash cleaning operation shall be carried out to prevent the accumulation of ash on the surface of the filter bag. Woodworking dust collector is composed of three parts: cyclone, ash hopper and volute (or air collecting cap). According to the number of cylinders, there are five combinations of single cylinder, double cylinder, three cylinder and six cylinder. Each combination has two kinds of air outlet forms: type I horizontal air outlet and type II (upper air outlet). For type I double cylinder combination, there are two combination forms of central air inlet and side air inlet and outlet, The type I single cylinder and three cylinders only have side air outlet, while the combination of four cylinders and six cylinders only has middle air inlet and outlet. For the type II combination, any one of the above type I air inlet positions can be used. This kind of dust removal equipment has the characteristics of small resistance, high dust removal efficiency, large air handling capacity, stable performance, small floor area, simple structure, practical and cheap, It is suitable for all kinds of mechanical processing, metallurgical building materials, mining dust coarse, intermediate purification.

Technical features of woodworking bag filter:
