是在袋式除尘器的基础上改进的新型脉冲除尘器，综合了分室反吹各种脉冲喷吹除尘器的优点，克服了分室清灰强度不够，进出风分布不均等缺点，扩大了应用范围。 Pulse precipitator is a new type of pulse precipitator improved on the basis of a bag type precipitator. It combines the advantages of various types of pulse jet dust collectors with reverse blowing in the compartment, overcomes the shortcomings of insufficient ash removal intensity in the compartment, and uneven distribution of inlet and outlet air. The scope of application.
The working principle of pulse bag type dust collector: Dust-containing gas enters the filter room from the ash hopper (or the wide open flange at the lower part), and coarse particles fall directly into the ash hopper or ash bin. The dust gas is filtered by the filter bag, and the dust is retained in On the surface of the filter bag, the clean air passes through the mouth of the bag to the clean room and is discharged into the atmosphere by the fan. When the dust on the surface of the filter bag continues to increase, causing the resistance of the equipment to rise to the set value, the time relay (or differential pressure controller) outputs Signal, the program controller starts to work, open the pulse valve one by one, so that the compressed air is blown through the nozzle to clean the filter bag, the filter bag suddenly expands, and the dust attached to the surface of the filter bag quickly leaves the filter under the action of reverse airflow. The bag falls into the ash hopper (or ash bin), and the dust is discharged by the unloader. After all the filter bags have been sprayed, the dust collector resumes normal operation.
Features and uses of pulse bag type dust collector: Because the dust collector adopts pulse spray cleaning method. It has the advantages of good ash cleaning effect, high purification efficiency, large air volume, long filter bag life, small maintenance workload, and reliable operation. It is widely used in various industrial and mining enterprises such as metallurgy, building materials, machinery, chemicals, and mines. Industrial dust removal and purification, this series of dust collectors have a total of 6 specifications, each specification can be divided into two types with standard ash bucket type A and open flange type (without ash bucket) B, the structure is mainly composed of filter , Filter bag, clean room, ash bucket, ash discharge valve, pulse injection device, electric control box, etc., the box body is all welded structure, the maintenance door is sealed with foam rubber strips to ensure that the dust collector is tight and does not leak.
