The fabric and design of the filter bag filter bag should be as far as possible to seek the effect of filtering, easy dust stripping and use. The selection of filter bag filter bag is very important, it directly affects the dust removal effect of the filter bag, and the filter bag filter bag is selected from the following aspects: gas temperature, humidity and chemical properties, particle size, dust content Factors such as concentration, filter wind speed, and dust removal method.

Generally, the dust removal power of the new filter material is not high enough. After the filter material has been used for a period of time, due to the effects of sieving, collision, retention, dispersion, static electricity, etc., a layer of dust accumulates on the surface of the filter bag. This layer of dust is called the primary layer. The main filter layer of the filter material depends on the effect of the primary layer, and the filter material with larger mesh can also obtain higher filtration power. With the accumulation of dust on the surface of the filter material, the power and resistance of the filter bag filter will increase accordingly. When the pressure difference between the two sides of the filter material is large, some fine dust particles that have been attached to the filter material will be squeezed. .

When using the filter bag filter, we will find that the general filter bag filter is used in a high temperature environment, and it often encounters various problems such as incineration, corrosion, wear, and high concentration. Protective measures must be taken first when the dust collector is used.

The flue gas sometimes reaches 550 degrees in an instant, and many dust collectors cannot adapt to this environment, so a cooling method should be used for the dust collector. The medium of the bag filter gas to cool the high-temperature flue gas can use low-temperature air or water to generate some coolness. Whether it is cold air or water cooling, it can be directly cooled or indirectly cooled. These are the cold air that can help the flue gas. Cool, then drop the duster to be warm.

A variety of cooling methods are available on a scale and feature dust collectors with varying temperatures and uses. Some low-temperature flue gas can be added appropriately, if the temperature of the gas is inconsistent in the same dust removal system.
