Cutting and polishing dust air filter is a new type of Pleated cartridge air filter developed on the basis of conventional short-bag pulse dust collector. It not only combines the advantages of separate back blowing and pulse jet dust removal, but also lengthens the filter bag to give full play to the role of compressed air powerful jet dust removal. It overcomes the disadvantages of the low strength of back-blowing and dust-cleaning in separate chambers, and the shortcomings of pulse-jet dust-cleaning and dust filtration at the same time, and prevents the problem of dust reattachment and out-of-control, thereby increasing the filtration speed, saving energy consumption for dust cleaning and prolonging the life of the filter bag. . The electric control of the dust collector adopts advanced PLC programmable controller.
◆Working Principle
Cutting and polishing dust air filter is composed of ash hopper, upper box, middle box, lower box and other parts. The upper, middle and lower boxes are divided into chambers. When working, the dusty gas enters the ash hopper through the air inlet, the coarse dust falls directly into the bottom of the ash hopper, and the fine dust enters the middle and lower boxes upwards with the airflow turning, and the dust accumulates on the outer surface of the filter bag. The gas enters the upper box to the clean gas collection pipe - the exhaust duct, and is exhausted to the atmosphere through the exhaust fan. The dust cleaning process is to cut off the air outlet duct of the room first, so that the bag in the room is in the state of no air flow through, and stop the air and clean the dust in each room). Then open the pulse valve and use compressed air to carry out pulse jet soot cleaning. The closing time of the cut-off valve is enough to ensure that the dust stripped from the filter bag after blowing settles to the ash hopper, preventing the dust from being attached to the airflow after leaving the surface of the filter bag. The surface of the adjacent filter bag makes the filter bag clean thoroughly, and the exhaust valve, pulse valve and ash discharge valve are fully automatically controlled by the programmable controller.
◆Equipment Advantages
1. Structure. Cutting and polishing dust air filter.
Thickened plate, strong dust removal ability, high dust removal efficiency and low emission concentration.
2. Stability. Cutting and polishing dust air filter.
The operation is safe and reliable, and the maintenance and replacement of bags can be carried out in separate rooms under the normal operating conditions of the system.
3. Efficiency. Cutting and polishing dust air filter.
Long service life, the filter bag keel adopts polygonal shape, which reduces the friction between the filter bag and the keel, and prolongs the service life of the filter bag.
4. Convenience. Cutting and polishing dust air filter.
Air-tight design, good sealing performance, the inspection door is made of excellent sealing material, kerosene leak detection is used in the production process, and the air leakage rate is very low.
