The advantages of dust filter bag in stone factory

The advantages of the dust bag with the dust collector in the stone factory are close to zero emission and can meet the strict environmental protection standards; Good ash cleaning, can provide high ventilation, or can reduce the pressure difference; The extension of filter bag life, the reduction of cleaning times, so that equipment maintenance costs are reduced; High gas cloth ratio, small dust collector can be designed, and the energy consumption is reduced when the pressure difference is reduced; The reduction of investment and operating costs brings good economic benefits to users.

Coated polyester needled felt dust bag is made by non-woven needled process and heat setting and other treatment methods. It is widely used in industrial dust collection and dust control. Polyester needle felt filter material has good permeability, after heat treatment, the surface is smooth and smooth, not easy to deform, easy to clean.

The surface of the coated polyester needle felt dust bag is compounded with a layer of multi-microporous polytetrafluoroethylene (PTFE) film, which has the characteristics of smooth surface, air permeability, easy cleaning, filtration, low running resistance, less energy consumption, long service life, and realize "surface filtration".

Bag filter bag material, dust collection bag,dust collector bag is an efficient collection of dust particles in the dust gas products, but in different working conditions the material is not the same, and different materials of dust bags are also used in different industries, choose a suitable dust bag to make the dust removal efficiency of the dust collector twice the result with half the effort. Otherwise, not only the dust removal effect is not good, the life of the dust removal bag will be greatly shortened. There are many kinds of dust bag materials, various materials of dust bag use is not the same, the advantages are not the same, the applicable working conditions are not the same, so in the selection of dust bag filter bag, need to choose the size and quantity of filter bag according to the actual working conditions of the user, if there is no suitable it needs to be tailored according to the actual working conditions.

Cloth bag filter bag material

1. Room temperature cloth bag: The main material of room temperature cloth bag is polyester. Polypropylene fiber. High fiber raw materials such as acrylic do not need to be woven. The textile method is manufactured and has excellent penetration. The appearance is neat and elastic. The size is fixed. Easy removal of dust and other high-quality capabilities. It is mainly used for the removal of dust pollution industries and the treatment of normal temperature flue gas in general industrial companies.

2. Medium temperature bag: In recent years, with the development of bag dust collection level, China has used imported fiber synthesizers, and developed high-performance filter materials that can adapt to the harsh working environment and ultra-long life. The more common medium and temperature filters on the market have polymer fibers. PPS series polymer impregnation. Dust proof. Prevent pollution. The anti-erosion process can obtain the ideal filtration effect.

3. High-temperature cloth bags: the high-temperature cloth bags commonly used in the market are mainly P84. Glass fiber and other high temperature resistant fiber materials by textile. Non-woven fabric processing, which is characterized by good thermal stability. High filtration efficiency. Long service life and other characteristics. It is mainly used for dust removal equipment under various high temperature flue gas conditions, for the outdoor temperature of the interior must use DWD raw materials caused by high temperature cloth bags, and the general dust collection method can use polyester cloth bags.

The dust bag of the industrial dust collector should be replaced on time, otherwise it will harm the actual filtration effect of the dust collector and increase the friction resistance of the dust collector. So how often does the bag dust collector replace the bag?

How often the dust bag is replaced, the dust bag is like the air filter of the car, it should be replaced on time, otherwise it will harm the actual effect of the dust collector and improve the friction resistance of the dust collector operation.

The problem of how often to replace the bag is the same as the problem of how many years a mobile phone can be used and how many years a car can run. In addition to the quality of the product itself, it also has a lot to do with your correct use and careful maintenance.

1, first of all, how often to replace the bag dust collector is related to the quality of the bag dust collector you use, there is no doubt that the use time of good quality dust bags is higher than the quality of dust bags, so you want to use longer, please try to choose high-quality dust bags. Do not inspect cheap bags, we always believe that a price is a price.

Due to the fierce competition in the industry, some low-quality businesses use shoddy goods, and some enterprises covet cheap, purchased low-quality dust bags, resulting in reduced dust bags, which is also one of the keys to shorten the service life of dust bags.

2. In addition, how often the dust collector bag is replaced also depends on the operation time of the dust collector and the dust concentration value. Dust collector operation time eight hours a day and 24 hours a day the service life of dust collector bag is not the same.

3, filter wind speed: the filter wind speed of the dust collector is usually 0.8~1.2, too high wind speed will increase the pressure of the dust collector, the dust bag is too late to clean the dust, resulting in the dust bag clogging, too high filter wind speed will reduce the dust removal efficiency of the dust bag, but also cause damage to the dust bag.

4, low temperature condensation: when the smoke exhaust temperature is lower than the dew point, there will be condensation phenomenon, which makes the characteristics of the filter bag decline, and in serious cases, it will cause the ash plate on the surface of the filter bag or even fall off with the filter bed, which seriously affects the service life of the filter bag. In addition, the northern region is cold in winter, which is easy to cause the phenomenon of sticking cake on the inner wall of the ash bucket, so that the ash can not flow out normally.

The dust concentration value harms the service life of the dust collector bag, as the car walks the urban road and walks the rural dirt road, the same use time, their filter element dirty level is undoubtedly different, so the dust with high concentration value is replaced frequently.

The dust collector bag inside the dust collector that works for eight hours a day is generally replaced once every 2-3 years.

More harsh environments and more than eight hours of daily work in the dust collector internal dust collector bag is generally not replaced once every two years. The temperature, humidity, concentration, corrosiveness and particle size of the treated flue gas dust are all factors that directly affect the service life of the dust bag, so when selecting the dust bag, a special dust bag should be selected according to the characteristics of the flue gas.

The time to replace the dust bag can be referred to according to the theoretical data information, but also according to the specific application situation, in theory, the dust bag can be replaced after 2 years of application, but in the usual work, the different working conditions of the dust bag caused by the level of damage is not the same, therefore, sometimes it will be used 1 year to replace once. Especially in the high temperature, strong corrosion of the natural environment, the dust bag is more easily destroyed, then the replacement time will be shorter. We have 3-month ones, we have 6-month ones, we have 8-month ones. In the practical application of the dust collector bag, the environment of the dust collector bag will also change with the frequent change of the working condition, and even beyond the requirements of the design performance of the dust collector bag, such as the abnormal increase in the concentration of dust and the abnormal rise in the temperature of the smoke exhaust will shorten the service life of the dust collector bag.

Dust bag is slowly damaged by dust, and cause such damage is the recreational power of dust, sometimes high temperature and the acidity of dust will lead to mold filter material, if the dust increases, it will cost more dust bag use period, then the replacement time may be shorter than 1 year.
