How to choose dust removal accessories of shot blasting machine correctly?
 
First, spray mist or foam dust removal is used as auxiliary.
On the one hand, for the flue gas with high temperature, the direct spray can realize evaporation cooling, which can cool the flue gas with a small amount of water, shrink the volume and reduce the speed, which is also conducive to dust removal. On the other hand, it can make the dust particles adhere to each other, solidify and grow up after wetting, and then they can be easily separated from the atmosphere. Therefore, from the perspective of emission reduction, energy saving and cost reduction, the unpowered dust removal and direct spray dust removal must be considered first.
Second, no power dust, dust.
For example, adding a chute during loading and unloading and belt operation can greatly reduce the processing capacity of dust and smoke; when handling bulk materials, local sealing should be adopted to make the generated dust and dust circulate and consume in it, and the dust will basically precipitate naturally. This kind of mechanical dust and dust removal accessories of shot blasting machine is called unpowered dust removal in foreign countries, and it is suitable to adopt unpowered dust removal in most places; or it is necessary to carry out unpowered dust removal pretreatment first, and prevention is always more cost-effective than treatment.
 
Ventilation and dust removal
When using the ventilation and dust removal system, first consider the low energy consumption of electrostatic precipitator, and finally consider the bag filter. Almost most of our country adopt ventilation dust removal, and use dust removal accessories, so the emission reduction problem is solved, but the operation cost is very high. Of course, the efficiency of some shot blasting machine dust removal accessories is also a practical problem to be solved
