Influence of Injection Pressure of Electromagnetic Pulse Valve on Dust Removal Efficiency of Precipitator

The function of the electromagnetic pulse valve is to produce a gas pulse that meets the standard injection requirements to achieve excellent cleaning effect. How to judge high-quality electromagnetic pulse valve? High-quality electromagnetic pulse valve should meet three conditions, 1 good switching characteristics; 2 good flow characteristics 3 reliable service life.

  The electromagnetic pulse valve injection gas volume and injection pressure are important factors that determine the cleaning effect of pulse bag filter bag filter. The volume of the air bag matched with the electromagnetic pulse valve and the pressure of the air bag gas during the injection are also decisive for the size of the pulse valve injection. In order to ensure the cleaning effect of the filter bag , it is very important that the air bag guarantees a certain volume and air supply.

  Adsorbed on the surface of dust when the dust bag filter dust bag filter, by electromagnetic pulse valve injection system periodically to the amount of air within the bag and blowing compressed air through the venturi induced, the filter cut off the gas flow, the rapid expansion of the bag instantaneously , Shrinkage and counter-blowing and other counter-blowing effects are cleaned. At the inlet of the dust collector, the concentration of gas dust, dust particle size and the filtration wind speed have been timed. The greater the injection pressure, the greater the amount of air injected into the filter bag and via the venturi tube, the greater the formation of anti-air blowing speed, The better the cleaning effect, the pressure loss of the dust collector will be significantly reduced. On the contrary, the injection pressure is low, the injection effect is not good, and the drop in the pressure loss of the dust collector is not significant. Although the high injection pressure can increase the filtration speed or the dust concentration, it can also bring about other adverse consequences when it is too high. If the blowing pressure is too high or too low, the dust removal effect of the dust collector will be affected.
