How to deal with the large differential pressure before and after the dust collector

Replace the filter, or clean the filter

Summary. Hello, the reason for the large pressure difference is that the dust collector bag and induced draft fan are not suitable, and the applicable performance of the filter bag is not considered in the early stage of the dust collector design, resulting in the increase of the overall pressure difference of the system.

Hello, the reason for the large pressure difference is that the selection of the dust collector bag and the induced draft fan is not suitable, and the applicable performance of the filter bag is not considered in the early stage of the combustion disturbance of the dust collector Huishan design, which leads to the increase of the overall pressure difference of the system.

Solution: Conduct an overall investigation of the system problem, eliminate and calculate the wind pressure of the induced draft fan and the resistance of the pipeline system, and select the appropriate filter material or replace the fan. Reason 2 for the large pressure difference:

The dust adhesion is strong under the dust working condition condition, and the phenomenon of pasting bags is caused to the dust collector cloth bag, and the existing ash cleaning system can not achieve the ash cleaning effect, and the pressure of the dust collector of the part increases, and the pressure difference is too large. The third reason for the large pressure difference: the configuration of the dust collector system is too low, and the automatic ash cleaning is not timely.

Solution: upgrade the dust collector configuration system, to increase the system timing, muchang constant pressure, manual three cleaning methods, according to the relevant nature of the dust, to adjust the timing time, regularly check the reason for the large pressure difference four: the filter wind speed is too high, the concentration in the dust is too high, and the filter wind speed of the filter bag at this time is also high, resulting in the filter bag pressure difference is too high.

Summary. Hello, glad to answer for you. Kissing, high differential pressure of water dust removal; The differential pressure reading is incorrect, and it is necessary to clean the pressure measurement interface Check the trachea for cracks Check the differential pressure gauge.

Hello, glad to answer for you. Dig the acorn jujube pro, and the water dust removal pressure difference is high; If the differential pressure reading is incorrect, it is necessary to clean the pressure measurement interface, check the trachea for cracks, and check the differential pressure gauge to dismantle.

1. If the temperature of the dust-containing gas is too high, if the bag filter system does not adopt insulation measures, so that there is a large temperature difference between the dust in the bag filter and the outside environment from the pipeline, the heat exchange will be cooled and the precipitation of water vapor will cause condensation in the car, which will increase the humidity and viscosity of the dust.

At this time, insulation measures should be taken for pipelines and bag filter equipment, or pre-cooling of the exhaust gas;

Improper setting of the relevant parameters of the pulse injection system will lead to poor cleaning effect of the bag filter. For example, the time interval between the pulse injection of the filter bag is too long, the pulse injection width is too short, and the compressed air pressure is too low and leaks, resulting in the reduction of the tension of the coarse mold filter bag, and the dust on the filter bag will accumulate too thickly. At this time, the relevant parameters of the pulse injection system should be re-set to make it consistent with the actual dust filtration.
