Dust removal equipment is the equipment to separate dust from flue gas, also known as dust remover or dust removal equipment. Dedusting equipment is to use underground dedusting water pipes and pressure pipes, add certain additives into the water, introduce wind pressure, and complete a series of process flow through special equipment to produce foam, and spray through the distributor and sprinkler bracket components to the dust source. Dust removal equipment will also have air leakage.

If this phenomenon occurs, it will cause a series of serious consequences. When the dust removal equipment works normally, it needs the pulse valve to control. If there is air leakage, all the pulse valves will stop working because the pressure can not reach, thus making the whole dust removal equipment in a paralyzed state. The dust removal research on this phenomenon has found some common problems The reasons are as follows;

1. The diaphragm in the electromagnetic pulse valve is damaged. If this is the reason, we need to replace it.

2. There is a problem with the gasket in the pulse valve, which can not contact with the end face very well. It may be that there is rust or some other debris in the production process of the end face. When we install the dust removal equipment, we must remove the dust on the surface of the end face in advance, and after removing the rust, we can solve the problem in the installation.

3. Some of the dust removal equipment use submerged pulse valve. If the injection pipe in the device is damaged, the compressed air will be discharged directly and cannot enter the next cycle. The solution is to replace the Populus euphratica.

Dust removal equipment is a hot product, the importance of pulse valve has been fully reflected in these years, although its production technology has been very mature, there are still some problems in practice.
