What is the dust removal efficiency of bag filter? Bag filter has high working efficiency, generally speaking, the dust removal efficiency is above 99%; the use is very flexible, and the dry material recovery is also very convenient; bag filter is operable. Therefore, bag filter has been widely used in many industries, such as food metallurgy, ceramics, chemical cement and other fields in China.

Bag filter is one of the most efficient and dust removing equipment among all dry dust removing equipment, which is a device to separate dust from exhaust gas. Boiler control dust collector is a commonly used auxiliary equipment in the production of boilers and industrial enterprises, and its role is to remove the particulate dust in the boiler fuel and combustion flue gas, thus greatly reducing the amount of dust discharged into the atmosphere. In recent years, with the rise of new filter media and pulse backblowing dust removal technology, bag filter and pulse dust collector development is rapid.

Bag filter is a kind of dry dust collector, the filter bag is made of woven filter or non-woven felt, dusty gas can be filtered by the way of filtering action of fiber fabric. When the dusty gas enters the bag filter, the dust with large particles and large specific gravity will settle down and fall into the dust hopper. When the gas containing fine dust passes through the filter material, the dust will be blocked and the gas can be effectively purified.

Generally speaking, the mesh size of the filter material that comes with the bag filter is larger, so the dust removal efficiency level of the new bag filter is lower, only about 40%. Compared with the cartridge material, the dust removal efficiency of the porous primary layer is much higher. The conditions for the formation of the initial layer are: the dusty gas passes through the filter material, because the cartridge material itself contains fibers, and the gas passes through the process of fiber interception, screening and so on, and the dust is retained on the filter material. Therefore, with the help of the initial layer and the gradually accumulating dust layer, the bag filter finally realizes the filtering function. At the time of actual filtration, the number of filtrations made is relatively high. With more and more solid particles, the dust removal efficiency decreases to varying degrees. Therefore, once the bag filter is used for a long time, it should be cleaned from time to time to remove solid particles in time, which can further improve the efficiency of the bag filter.

Bag dust collector is very suitable for capturing fine dust, according to the needs of different enterprises, dust concentration, the main distribution of various particle sizes, dust conductivity size can be changed, and can be selected at the same time according to the market demand for analyzing the size of the treatment system air volume. Pulse dust collector is a new type of dust collector improved on the basis of bag dust collector, summarizing the strengths of various different pulse blowing dust collectors with compartmentalized blowback, overcoming the compartmentalized clearing strength is not good, uneven distribution of inlet and outlet air and other defects, expanding the scope of application of dust collector technology. Pulse bag filter has the advantages of strong processing capacity, high purification efficiency, long bag life, stable performance, easy operation and small workload of maintenance personnel.

Due to the rise of new filter media and pulse reverse blowing dust removal technology, the bag filter has developed rapidly. Today, baghouse dust collectors are available in a variety of standards, with a high degree of automation and easy maintenance. At present, bag filter can be used to purify various kinds of dusts, such as sticky dust, dust in high temperature gas, dust in high humidity gas and air containing ultra-fine dust.
