Electric-bag Composite Dust Collector
By using a high-voltage direct current electric field, the dust particles in the dusty gas are charged, and under the action of the electric field force, they deposit on the surface of the settling electrode. Then, under the action of the vibration force, the flaky dust falls into the ash hopper, which purifies the flue gas passing through the electrostatic precipitator and meets the environmental protection emission standards. It is an ideal equipment for purifying industrial waste gases such as thermal power generation, metallurgy, papermaking, building materials, and non-ferrous metals.

By using a high-voltage direct current electric field, the dust particles in the dusty gas are charged, and under the action of the electric field force, they deposit on the surface of the settling electrode. Then, under the action of the vibration force, the flaky dust falls into the ash hopper, which purifies the flue gas passing through the electrostatic precipitator and meets the environmental protection emission standards. It is an ideal equipment for purifying industrial waste gases such as thermal power generation, metallurgy, papermaking, building materials, and non-ferrous metals.
The Electric-bag Composite Dust Collector is a new type of high efficiency dust collectolwhich combines the electrostatic precipitator and the bag filter. lt combines two different types ofdust removal methods, fully exerts the advantages of two kinds of dust removal methodsachieves the best dust removal effect and the reliability of the equipment, and can overcome theelectrostatic precipitator and the bag filter in the same time. Their own shortcomings The dustcollector has the advantages of high efficiency, stable dust removal efficiency, low filter bagresistance, long life, small equipment investment,low running cost and small occupied area.
Technical Description
A、The airflow passageway is smooth, the rotation angle and the contraction change are small, and theflue gas flow rate changes smoothly to avoid sudden enlargement or sudden reduction, and themechanicalresistance of the dust collectoris small.
B、Since the front-stace electrostatic precipitator has captured most of the dust and charged the finedust, the wav to the surface of the filter bag is short, This reduces the filter load on the bag filter, and onthe other hand, the fine particles are arranged in an orderly manner on the surace of the filter bag afteibeing charged, which reduces the resistance of the dust layer and reduces the resistance of the filterbag.
C、The internal space is large, electric and bag is connected reasonably, effectively ensuring thedistribution of the electric field section, and maximally exerts the efficiency of the dust removal in theelectric field area: the flow velocity in the periphery of the bag is low, and the balance of the flue gas flow is good.
D、The structure is simple and compact, which is very suitable for the efficiency improvement of ESP.
E、Compared with theconventional bag filter， theamount of dust deposited inthe same bag area per unittime is small.and thecleaning period of the filterbag can be lO times higherthan that of the conventionalbag filter. The ash removalfrequency and the ashremoval number arereduced,and the service lifeof the filter bag and the pulsevalve is greatly prolonged.
