Plate, the support foot plate are equipped with threaded connection hole.
Electrostatic cyclone provided by the utility model, advantage are：1, air inlet, which uses, rotates 180 °
Volute air-inlet mouth, the influence to internal gas flow is smaller, advantageously reduces interfering with each other for air-flow, substantially reduces air-flow and short circuit occurs
Chance, the large dust particle of tube wall is struck after can effectively trapping into deduster inside, while 20%- can be reduced
30% resistance shortens the distance of particle movement, efficiency of dust collection is made to increase；2, using contraction type exhaust pipe, lower end is by common
Straight barrel type makes contraction type into, and this design neither influences efficiency of dust collection, and can reduce resistance, is suitable for detaching thinner dust
Particle；3, the lower pipe end of contraction type exhaust pipe is concordant with the lower edge of volute air-inlet mouth, can reduce the small rotation of annular space
Vortex air flow, the pressure loss are smaller；4, the high-efficiency dust remover that collection electrostatic technique and cyclone technology are combined, electrostatic technique can be effective
Solve the problems, such as that single cyclone dust collectors are not easy the drawback trapped, efficiency of dust collection is low for grain size less than 5 μm of dust, there is height
Efficiency of dust collection and the characteristics of high gas flow can be handled, for dust particles of the grain size more than 5 μm using cyclonic principle to it
Dedusting, and the dust for grain size less than 5 μm then uses electrostatic principle to its dedusting；And combine cyclone technology can be to avoid installation
Ash removal equipment for flapping realizes automatic continuous deashing function using internal swirling eddy, reduces manufacturing cost, easy to maintenance, is
Electric precipitator overcomes back corona phenomenon to provide new approach, efficiently solves the problems, such as secondary fly-up；5, in the case of good seal,
With higher efficiency of dust collection, it is advantageously ensured that air cleaner, meets environmental requirement.
