Pulse bag filter

 Pulse bag filter is a new type of pulse bag filter improved on the basis of bag filter. In order to further pulse bag dust collector, the reformed pulse bag dust collector retains the advantages of purification, large capacity of processing body, stable performance, convenient operation, long life of filter bag and small maintenance workload.

And reform from the structure and pulse valve, solved the problem of open-air placement and low pressure of compressed air source.

   Working principle of pulse bag filter

   Pulse bag filter consists of dust hopper, upper box, middle box, lower box, etc. The upper, middle and lower boxes are divided into chambers. When working, the dusty gas enters into the dust hopper from the inlet duct, the coarse dust particles fall into the bottom of the dust hopper directly, the fine dust particles enter into the middle and lower box with the airflow turning upwards, the dust accumulates on the outer surface of the filter bag, the filtered gas enters into the upper box to the clean gas collection pipe - exhaust duct, and then discharged to the atmosphere by the exhaust fan. Cleaning process is to cut off the clean gas outlet duct of the room first, so that the bag in the room is in the state of no airflow through the state (room air cleaning). Then open the pulse valve with compressed air pulse blowing cleaning, cut off the valve closure time is enough in the blowing from the filter bag on the stripping of dust settling to the dust hopper, to avoid the dust in the surface of the filter bag from the filter bag and then with the airflow attached to the neighbouring filter bag surface of the phenomenon of the dust bag cleaning, and by the programmable programmable control instrument on the exhaust valve, the pulse valve and the ash removal valve, etc., for fully automatic control.

Features of pulse bag dust collector

1、 Pulse bag dust collector adopts the technology of clearing the dust by pulse blowing in a separate chamber and stopping the wind, which overcomes the shortcomings of the conventional pulse dust collector and the separate chamber reverse blowing dust collector, clearing the dust, removing the dust, with low concentration of emission, small air leakage rate, less energy consumption, less steel consumption, less occupying area, stable operation, and good economic benefits. It is suitable for purification of dusty gas and material recovery in metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry.

2、Because of the use of a chamber stop pulse blowing cleaning, blowing once can achieve the purpose of cleaning, so the cleaning cycle is prolonged, reducing the cleaning energy consumption, pressure gas consumption can be greatly reduced. At the same time, the fatigue degree of the filter bag and pulse valve is also reduced accordingly, so as to improve the life of the filter bag and valve piece exponentially.

3, maintenance and bag change can be carried out without stopping the system fan, the system under normal operating conditions in separate rooms. The bag mouth of the filter bag adopts elastic ring, with good sealing performance and firmness. The filter bag keel adopts polygonal shape, which reduces the friction between the bag and the keel, prolongs the life of the bag, and facilitates the unloading of the bag.

4、Using the upper part of the bag extraction method, after extracting the skeleton when replacing the bag, the dirty bag is put into the grey hopper in the lower part of the box, and taken out by the manhole, which makes it easy to change the bag operation conditions.

5、The box adopts airtight design with good sealing, the inspection door is made of excellent sealing material, and the leakage rate is very low due to paraffin leakage check during the production process.

6、Inlet and outlet ducts are compactly arranged, with small airflow resistance.
