Several Dust Removal Methods of Bag Filter

The bag filter is a widely used dust removal equipment, which can treat all kinds of industrial dust with high dust removal efficiency. The use of this equipment can reach the specified dust concentration emission standard.

There are several dust removal methods for bag filter, but the specific dust removal method still needs to be selected according to the specific dust removal conditions, then how to choose the dust removal method of the bag filter? The following editor will explain in details.

1. Manual beat

This method of cleaning dust mainly relies on manual or mechanical vibration to produce high-frequency vibration. Although this method of cleaning dust is relatively simple and convenient, it wastes manpower and time cost, and is also prone to uneven vibration, which may cause damage to the filter bag.

2. Gas cleaning

This kind of dust removal method mainly relies on outdoor or circulating air passing through the filter bag in the opposite direction of the dust-containing air flow, and then the dust on the filter bag is dropped. The cleaning gas can be supplied by the main fan, or a separate blowback (suction) fan can be set up.

This method of cleaning dust can make the gas distribution more even when passing through the filter bag, but pay attention to the wind speed not too high.

3. Sonic cleaning

This kind of dust cleaning method mainly uses a sound wave cleaner to make the dust bag vibrate to achieve the purpose of dust cleaning. This ash cleaning method has low power consumption and relatively small loss of dust removal equipment, but it is too expensive.

4. Pulse cleaning

This kind of dust removal method is mainly based on the compressed air guiding the surrounding air into the filter bag in a relatively short time, so that the dust will fall off when the filter bag generates pulse expansion and vibration.

This kind of dust removal method has strong dust removal ability and good effect. The wind speed of the filter is relatively high, and the dust can be removed while working. It is the current cleaning method with better dust removal effect. However, since the pulse cleaning adopts high-pressure compressed air, it is easy to cause certain loss to the dust removal bag. Therefore, when choosing this dust removal method, it is best to choose the dust removal bag that is thick and wear-resistant.

Whether the dust removal effect is good or not will affect the resistance of the filter bag. If the dust is not cleaned, the resistance of the filter bag will also increase, thereby affecting the dust removal effect. Therefore, in order to achieve a good cleaning effect, different cleaning methods must be selected according to different working conditions.
