펄스제트 집진기의 최적 분사압력은 얼마입니까??

주입 압력: 펄스밸브가 열려 압축공기가 집진기에 주입되는 압력. 분사압력이 높을수록, 송풍 속도가 빨라지고 청소 효과가 좋아집니다.. 백필터의 압력 강하가 제한된 후, 사출압력이 높을수록, the greater the processing capacity. 하지만, if the injection pressure is too high, the phenomenon of excessive dust cleaning will also occur: the bag filter has an instant “ash” phenomenon, which will affect the purification efficiency. It can be seen that the filtration effect will be affected if the injection pressure is too low or too high.

 

A considerable part of the pressure of the compressed air is consumed in overcoming the resistance of the injection system itself, and its value can reach more than 0.2MPa, of which the resistance of the pulse valve accounts for a large part. 최근에는, several low-resistance pulse valves have appeared, such as straight-through pulse valves and double-diaphragm low-pressure pulse valves. Because its internal resistance is greatly reduced, the injection pressure is also reduced accordingly, and the minimum injection pressure can reach 0.2-0.3MPa.

게다가, increasing the diameter of the air bag and the injection pipe, and replacing the injection hole with a nozzle can reduce the injection pressure.

In addition to considering the resistance of the pulse valve, the injection pressure should also consider the length of the filter bag. The short filter bag should use a low injection pressure, and the long filter bag should increase the injection pressure accordingly.

For a filter bag with a length of 2m and a low-pressure straight-through pulse valve, the injection pressure is generally not greater than 0.45~0.55MPa.

Most of the flat bag dust collectors use high-pressure angle pulse valves, and the injection pressure can be appropriately increased to 0.6MPa.
