How to deal with the air leakage phenomenon of GA series air dust remover?

GA series of atmospheric dust bag type dust collector is by manual welding, because there are more or less a flat spot welding, bag room temperature is lower than the dew point of gas and filter bag can be affected with damp be affected with damp, the dust is not loose, but thick paste adhesive on the filter bag, the fabric hole closed, invalidate ash removal, the filter pressure drop is too big, can't continue to run, some paste bag dust removal to the average.

To prevent air leakage, keep the temperature of gas in the dust collector and all parts of the system above its dew point of 25 ~ 35℃ (such as the dew point of kiln grinding machine 58℃, the operating temperature should be above 90℃), to ensure the good use of dust filter bag.

Its measures are as follows:

Act appropriately.If the dust collector is equipped with far infrared electric heater, electric heater, or set up in the bag indoor radiator, the smoke temperature of the host can be appropriately increased.Strengthen the temperature monitoring of dust remover and dust removal system, so as to grasp the use conditions of GA series air dust remover and prevent air leakage.

Heap shelter for raw materials.In cement production, the moisture content of various raw materials, fuels and mixed materials is different. If placed in a fixed storage shed, the moisture content of materials can be greatly reduced to prevent rain, which is an effective measure to reduce the moisture content of materials.In the south of China's cement plant this kind of situation is more common, but the material pile shed some too small, some do not, therefore, to the GA type series air dust cloth bag filter use caused difficulties.

Reduces air leaks.Air leakage from some crevices on the body of ga-type air dust remover should be controlled below 3%.Air leakage of process equipment in the dust collector system, such as the closed dust discharge valve of the discharge port of the ball mill, air leakage of the closed star type discharge device under the dust collector, pipe flange connection, etc.

Dust gas should be evenly distributed in the single-machine pulse dust collector, prevent eddies in the corners so that the amount of gas through here to reduce the formation of local low temperature and air leakage problem.

Do good dust collector, pipes and other relevant everywhere insulation and rain.Practice has proved that good insulation measures can make GA series air dust cleaning cloth bag precipitator inlet and outlet temperature difference is very small, which is an effective measure to prevent air leakage.
