Carbon black industry--Dust removal equipment for carbon black industry

1.Carbon black dedusting equipment

Carbon black dust removal equipment is a kind of dust remover equipment, with dust removal efficiency of more than 95%, and the resistance of dust remover body is lower than 900pa. The normal operation of boiler can be ensured by using the existing boiler induced draft fan. The load adaptability of carbon black bag dust remover is good. At 70% load, the dust removal efficiency is over 94%, which has the characteristics of corrosion resistance.

The filtration process of carbon black dust removal equipment is mainly carried out in the stage. Therefore, the dust removal equipment in carbon black industry has high efficiency, mainly by the role of dust layer formed on the filter material. The filter cloth is mainly used to form and support the dust layer. In addition, the primary layer of dust should be kept during the dust cleaning. Excessive ash removal will cause significant reduction of efficiency and accelerate the damage of filter bag.

Because of its high temperature and high corrosion, the production process of carbon black is more complex in the selection of dust remover. According to the advantages of large air volume, small area of dust removal bag, long service period and simple operation of equipment, our company has many years of carbon black bag dust remover.

There are 33 specifications for carbon black dust removal equipment. There are 32, 64, 96 and 128 bags in each room. The filter bags are 2450mm and 3060mm in length. The dust collection efficiency can reach above. The dust concentration of the purified gas is less than 100mg/m3 (standard). If the dust collector is used in cold areas, when the outdoor heating calculation temperature is < - 25 ℃, heat device shall be set.

 

 

2.Dust collector for carbon black plant

Due to the characteristics of high temperature and high corrosiveness, the selection of carbon black bag filter is more complex. Our company has many years of experience in carbon black bag filter, such as large air volume, small floor area, long service life of bag filter, simple equipment operation and so on.

There are 33 kinds of specifications of carbon black plant dust collectors. There are four kinds of bags in each room, including 32, 64, 96 and 128 bags. There are two kinds of filter bag length, 2450 mm and 3060 mm. The dust collection efficiency can reach above, and the dust concentration of purified gas is less than 100 mg / m3 (standard). If this series of dust collectors are used in cold areas, when the calculated temperature of outdoor heating is less than - 25 ℃, heat devices should be set.

The dust remover used in carbon black plant is a new type of dust remover. The dust removal efficiency can reach more than 95%, and the resistance of the dust remover body is lower than 900pa. The normal operation of the boiler can be ensured by using the existing boiler induced draft fan.

At 70% load, the dust removal efficiency is more than 94%, which has the characteristics of high efficiency and corrosion resistance. Carbon black bag filter or dedusting equipment is the equipment to separate dust from flue gas. The black carbon bag filter, also known as the filter type dust collector, is a kind of dry type dust collector. It is a dust removal device that uses the bag filter element made of fiber fabric to capture the solid particles in the dust containing gas. Its working principle is that the dust particles are intercepted when they bypass the filter cloth fiber due to the impact of inertial force with the fiber. Bag filter is a kind of dry dedusting device, which is suitable for collecting fine, dry non fibrous dust.

The filter bag of carbon black plant dust remover is made of textile filter cloth or non-woven felt. The filtering function of fiber fabric is used to filter the dusty gas. When the dusty gas enters the bag dust remover, the dust with large particles and large proportion will settle down due to the action of gravity and fall into the ash hopper. When the gas with small dust passes through the filter material, the dust will be retained and the gas will be purified. Generally, the dust removal efficiency of new filter materials is not high enough. After the filter material is used for a period of time, due to the effects of screening, collision, retention, diffusion and static electricity, a layer of dust is accumulated on the surface of the filter bag, which is called the primary layer. In the later movement process, the primary layer becomes the main filter layer of the filter material. Depending on the role of the primary layer, the filter material with larger mesh can also obtain higher filtration efficiency.

With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the bag filter increase correspondingly. When the pressure difference between the two sides of the filter material is very large, some fine dust particles that have been attached to the filter material will be squeezed to reduce the efficiency of the filter. In addition, the high resistance of the dust collector will significantly reduce the air volume of the dust removal system. Therefore, after the resistance of the dust collector reaches the value, it is necessary to clean the dust in time. The initial layer should not be damaged during ash cleaning to avoid the efficiency decline.
