◆Working Principle
When the dust-laden flue gas enters the ash hopper from the air inlet, some coarse dust particles fall into the ash hopper here due to the principles of inertial collision and natural sedimentation. , the dust particles are blocked outside the filter bag, the purified flue gas enters the box from the inside of the filter bag, and then is discharged into the atmosphere through the valve plate hole and the air outlet to achieve the purpose of dust collection and purification. When the dust accumulation on the outside of the filter bag gradually increases, the running resistance of the dust collector also gradually increases. When the resistance increases to the preset value (1245-1470Pa), the dust cleaning controller generates a signal, and first controls the lifting The valve closes the valve plate hole, cuts off the filtered flue gas flow, stops the filtering process, and then opens the electromagnetic pulse valve to spray compressed air with a pressure of 0.5-0.7MPa in a very short time (0.1-0.15S). The box expands rapidly, and when it pours into the inside of the filter bag, the filter bag will be deformed and vibrated, coupled with the effect of reverse airflow, the dust outside the filter bag will be removed and fall into the ash hopper. After the dust is cleaned, the poppet valve will be opened again , the dust collector enters the filtering state again.
The above-mentioned working principle only shows the case of one working room. In fact, the air box pulse dust collector is composed of multiple working rooms. When cleaning dust, each working room is carried out sequentially. This process is the off-line cleaning of separate rooms. Its advantage is that the cleaning room and the working room being filtered do not interfere with each other, realizing continuous operation and improving work efficiency.

◆Equipment Advantages
1. Structure. Pulse Type Self Cleaning Inlet Air Filters.
The theme is composed of four parts: the box body, the bag room, the ash hopper, and the air inlet and outlet.
2. Cabinet
It is small in size and has a manhole inspection door on the top. It is very convenient to install and replace filter bags and bag cages here.
3. Bag room
Good sealing performance. It is divided into several rooms according to different specifications and separated by steel plates to prevent mutual interference between the rooms during cleaning.
4. Hopper
The dust cleaning effect is good. In addition to storing the collected dust, it is also used as the main intake pipe (bottom air intake type).
