For pulse bag dust collectors, many people think that the impact of compressed air pulses on the filter bag plays a major role in cleaning the dust.
High-pressure low-gas pulse bag filter will be able to extend the life of the filter bag optimally. Of course, the injection pressure should not be too high, and there should be a “degree” for anything. If the cleaning pressure is too strong, the filter bag may also crack the bag due to severe friction with the bag cage due to the strong oscillation force. Therefore, regardless of the use of high, medium or low pressure air sources, the equipment’s cleaning power and flow rate must be reasonably configured by comprehensively considering the process and site conditions and the nature of the filter material. In actual use, there is no strict boundary between high, medium and low pressure, only in relative terms.
The cleaning pressure is not the only factor that determines the size of the cleaning force (ie, reverse acceleration) of the filter bag. The low-pressure cleaning force on the filter bag is not necessarily smaller than the high-pressure cleaning, and it cannot be filtered from the level of the cleaning pressure. Judgment basis of bag life. Large aperture and low blowing pressure can also make the filter bag generate greater acceleration.
