Differences between positive pressure cloth bag dust collector and negative pressure cloth bag dust collector:

Differences between positive pressure cloth bag dust collector and negative pressure cloth bag dust collector:

 

 

(1) bag dust collector negative pressure dust removal system in the negative pressure dust removal system, the dust collector is set before the ventilator. (its features are described below)

 

 

(1) because the dust collector set in front of the fan, the gas has been through the fan dust, dust concentration is low, fan wear greatly reduced, long service life, the treatment of high concentration of dust gas, the general use of negative pressure dust removal system.

 

 

 

(2) dust remover and pipeline in the fan of the negative pressure section, easy to breathe in air, air leakage. The air leakage rate of the negative pressure dust removal system is 5% ~ 10%, which increases the air volume of the ventilator and increases the power consumption.

 

 

 

(3) in the negative pressure dust removal system design should adopt measures to reduce the dust collector and pipe air leakage, to ensure the good operation of the dust collector.

(2) in the positive pressure dust removal system of cloth bag dust collector, the dust collector is set after the ventilator (positive pressure section or pressure out section). Its characteristics are described below.

 

 

 

(1) as a result of the flow of fan dust gas without dust collector purification, fan impeller and shell easy to wear dust. Therefore, the positive pressure dust removal system is only suitable for use under the condition of gas dust concentration below 3g/m3, weak dust grinding and small dust particle size.

 

 

 

The dust collector is in the positive pressure section of the fan. There is no need to consider the additional rate of air leakage of the dust collector.

 

 

 

(3) dust collector envelope structure is simple, such as positive pressure bag filter envelope structure does not need to be sealed, as long as rain can; Equipment manufacturing, easy installation, low cost.

 

 

 

(4) bag dust collector positive pressure dust removal system, the purification of the gas directly from the dust collector into the atmosphere, not set up a chimney; The dust collector has a certain effect of silencing, and the outlet side of the ventilator may not have a silencer. Beneficial to save dust removal system occupation and initial investment.
