Industrial Pulse Bag Filter Powder Dust Collector

Working mechanism:

pulse bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. It is composed of ash bucket, upper box, middle box, lower box and so on. The upper, middle and lower box are divided into chambers. When working, the dusty gas enters the ash bucket from the inlet air duct, the coarse dust particles directly fall into the bottom of the ash bucket, the fine dust particles enter the middle and lower boxes upward with the airflow turning point, the dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean gas collection tube - exhaust air duct, and is discharged to the atmosphere by the exhaust fan. The cleaning process is to cut off the chamber's clean air outlet duct first, so that the cloth bag of the chamber is in a state of no air flow through (separate chamber to stop the air cleaning). Then the pulse valve is opened and the compressed air is used for pulse spray cleaning. The closing time of the cut-off valve is enough to ensure that the dust removed from the filter bag after spraying will settle to the ash hopper, so as to avoid the dust from the surface of the filter bag and then attached to the surface of the adjacent filter bag with the air flow, so that the filter bag can be cleaned. In addition, the automatic control of the exhaust valve, pulse valve and ash discharge valve is carried out by the programmable controller.

Features:1, the use of separate chamber air stop pulse jet dust cleaning technology, overcome the shortcomings of the conventional Pulse Dust Collector and separate chamber backblowing dust collector, strong dust removal capacity, high dust removal efficiency, low emission concentration, small air leakage rate, less energy consumption, less steel consumption, less land area, stable and reliable operation, good economic benefits. Suitable for metallurgy, building materials, cement, machinery, chemical, electric power, light industry dust gas purification and material recovery. 2. Due to the use of separate chamber air stopping pulse injection for cleaning ash, the purpose of cleaning ash can be achieved in one time, so the cleaning period is extended, the energy consumption of cleaning ash is reduced, and the pressure gas consumption can be greatly reduced. At the same time, the fatigue degree of the filter bag and pulse valve is reduced, which increases the life of the filter bag and valve disc exponentially. 3. Maintenance and bag changing can be carried out in separate rooms without stopping the system fan and under the condition of normal operation of the system. The filter bag mouth adopts elastic coil, good sealing performance, firm and reliable. The filter bag keel adopts the polygonal shape, which reduces the friction between the bag and the keel, prolongs the life of the bag, and is easy to unload the bag. 4. The upper part of the bag is pumped. After the skeleton is pulled out during bag changing, the dirty bag is put into the ash bucket at the lower part of the box and taken out from the manhole to improve the operating conditions of bag changing. 5, the box adopts air tightness design, good sealing, inspection door with excellent sealing materials, the production process with kerosene leak detection, air leakage rate is very low. 6, inlet and outlet air duct layout is compact, small airflow resistance.
