Key points for purchasing dust bags

The filter bag is the core component of the bag dust collector. It is very important that the selected filter material can adapt to the flue gas temperature. If the normal operating temperature of the filter material exceeds the temperature of the flue gas by too much, equipment investment will increase due to the higher cost of high-temperature filter material. If the normal operating temperature of the filter material is lower than the temperature of the flue gas, the bag may be burned, causing great economic losses.
When choosing a dust bag
, you must first understand the temperature of the flue gas to be processed. Filter materials are divided into normal temperature filter materials
℃
or below and medium temperature filter materials
~< br/> ℃
, high temperature filter material
~
℃
. Once you know the flue gas temperature and the operating temperature of the filter material, you can select the filter material.
Then understand the composition of the flue gas, including the dust content, specific gravity, particle size, whether it is sticky, the moisture content of the flue gas and other parameters. The post-treatment methods of filter materials usually include microporous coating, water and oil repellency, antistatic (conductive yarn is added when weaving) and easy cleaning treatment, etc., depending on the situation. By understanding these resolutions, the dust cleaning method of the dust collector, the post-processing method of the filter material and the filtration wind speed are determined. Generally, pulse bag dust collectors are used for working conditions with large amounts of dust, relatively sticky and light dust, and the filtration wind speed is controlled above

in most cases, and below

for a small number of working conditions. . Others, depending on the situation, can use high-pressure backflush dust collectors and cyclone dust collectors.
