The application scope of bag filter is introduced

Bag filter is more common in our daily life, the application scale is very wide, let's have a comprehensive understanding of its use scale.

1. The advantages of bag filter are moderate and can be used in all walks of life. For example, in the crude oil range of the chemical plant, lubricating grease, aviation kerosene and other refined oil can be directly filtered out by the bag filter, but also can recover the metal catalyst, before the finished product canning security personnel can filter out the debris on the edge of the refined oil. In the edge of the coating industry, you can paint, phosphating agent body filtration. In sewage treatment and membrane industry production, the application rate is also appropriately high, can comb the dirt and other things in the water. Sewage treatment chemicals can also be combed.

2. Bag filter is closely related to our daily life and industrial production. The water we eat, the oil we use for our cars, the paint we use for our decorative designs. The filters will be used in building paints and other things. All because of its powerful practical effects. The characteristics of bag filter have shown great practical effect in many fields. At this stage, industrial production and many other places are essential. In the near future, the bag filter is the focus of the staff's research and development, and continue to develop towards the direction of higher technical content, in order to make more selfless dedication for us. Long history, earn a better future.

How to deal with bag filter clogging?

Nowadays, bag filters are used in the pharmaceutical industry. Food materials and other fields are widely used. According to the case differences, the bag filter can be divided into stainless steel plate bag filter, pp bag filter, PVDF bag filter and so on. The industry shows that bag filters are also contradictory due to the advantages and disadvantages of materials, so customers need to choose the right product for The Times according to their individual needs. Only at this stage to choose the right filter, many customers in the process of using feedback some problems, among which the relatively rare problem is: bag filter blocked, how to do? Is it a mechanical problem? According to the main principle of the bag filter, it is applicable to the external metal filter pipe, the liquid flows from the inlet to the inlet, the filter bag is filtered and then put into the inlet, the residue is blocked in the filter bag, and the replacement of the filter bag can continue to use. According to statistics, the customer's reaction to the bag filter blockage is indeed caused by the bag blockage, so what is the cause of its blockage? The industry suggests that there are many reasons for the filter bag blockage, the reason is that the filter speed is too high, the dust is too fine, the dust is sticky, the filter bag is not good, the filter bag paste bag, condensate, agglomeration and so on. For this matter, Xiaobian lists four rare and their coping points.

1. Filter bag cleaning is not good

According to statistics, if the bag filter often remove dust, in the case of dust removal may be too long, resulting in the setting of weapons equipment pressure is too large, it is easy to loose the chemical fiber structure of the filter bag, and then increase the fine dust in the dust, blocking the filter bag. In addition, if the dust removal time is too long, the original powder layer on the appearance of the filter bag will continue to be removed together, resulting in reduced filtering accuracy of the filter bag. However, the dust removal time is too short, and the dust on the appearance of the filter bag is not cleaned in detail, and then the filtration begins. Smoke and dust gradually accumulate on the appearance of the filter bag, which can also cause blockage. In dealing with the above problems, the industry advocates negotiating the blowback controller after a few trial runs.

2. Contain moisture

Water is the key reason for filter bag blockage. The reason of water is condensation caused by continuous high temperature, especially when dealing with ultra-low temperature dust. In this case, the following points are acceptable: avoid improper startup; Avoid starting the dust collector when the friction resistance is too large; Start at low leak point. The dust collector operates at a low leakage point, causing problems at will. If the air inlet dispersion is not uniform, it will lead to partial corrosion of the dust collector shell, so the dust collector should be avoided at the leakage point as follows. If Fucheng avoids continuous high-temperature startup, heat preservation installation such as steam insulation or electric heater insulation should be adopted.

3. The atmosphere seeps in

It is understood that the flannel of dust collector often appears atmosphere penetration. Detection door or dust collector action installation, if the seal is not tight, the internal structure atmosphere into the dust collector, in the treatment of ultra-low temperature dust, will produce high temperature area outside the dust collector, leading to continuous high temperature condensate, corrosion of the dust collector, resulting in filter bag paste bag or agglomerate.

4. High filter wind

According to statistics, if the dust collector operation of the filter wind exceeds the idea of the filter bag standard, the fine dust in the dust will enter the chemical fiber outside the filter bag, resulting in the bag plug, friction resistance is reduced. In this case, coated filter material, coated filter material or pre-coated ash treatment on the appearance of the filter bag may be accepted. But for the dust with large viscosity, it is necessary to reduce the filter wind, or increase the monopulse back blowing pressure, or accept the yoga layout of the monopulse ash cleaning filter bag. The industry shows that the key to better is to increase the total filter area, reduce the filter wind, and extend the life of the filter bag.
