TECHNICAL FIELD
[0001] The utility model relates to pulse dust collector technical field, concretely relates to a compressed air treatment device for pulse dust collector. BACKGROUND
[0002] Pulse dust collector is a new type of high efficiency pulse dust collector improved on the basis of bag type dust collector, which combines the advantages of various pulse jet dust collectors in divided chamber and overcomes the shortcomings of insufficient dust removal intensity and uneven distribution of air in and out of the chamber. In the use process of the pulse dust collector, the dust accumulated on the filter bag increases with time, which increases the resistance of the filter bag and reduces the processing air volume. In order to work normally, the resistance must be controlled within a certain range (140-170 mm of water column). Once the range is exceeded, the filter bag must be cleaned. When cleaning, the pulse control instrument sequentially triggers each control valve to open the pulse valve. The compressed air in the air pocket is injected into each corresponding filter bag through the nozzles and the venturi tube. The filter bag expands sharply at once, causing the dust accumulated on the surface of the filter bag to fall off. The filter bag returns to its original state, and the dust falls into the ash bucket and is discharged from the body through the ash removal system.
[0003] At present, when the compressed air enters the pulse dust filter, the water in the compressed air will adhere to the surface of the dust filter bag. In addition, if the temperature of the compressed air is too low, the temperature of the dust filter bag will also be reduced. As a result, the impurities in the flue dust are easy to stick to the inside of the dust filter bag due to the temperature difference and moisture, which reduces the cleaning effect of the pulse dust collector on the dust stuck on the filter core and affects the filtering effect of the flue dust.
