Cyclone cylinder is mounted in support device.
The cyclone cylinder includes straight tube and cone cylinder, and the wide mouth part of the cone cylinder connects straight tube, and the slot end of cone cylinder connects collection
Dirt bucket.
The upper pipe end of the contraction type exhaust pipe is higher than the top barrel of cyclone cylinder, the lower pipe end of the contraction type exhaust pipe
Whirlwind tube inner chamber is extended to, and the lower pipe end is concordant with the lower edge of the volute air-inlet mouth.
Barb type corona discharge electrode one end is fixed in contraction type exhaust pipe, and the other end is extending vertically under the straight tube
Portion.
The support device includes hanging support and bracket, and the cyclone cylinder is installed on bracket by hanging support.
The cradle top is equipped with several hanging supports, several described hanging supports are distributed along straight tube even circumferential,
It is supported on straight tube middle and lower part.
The hanging support includes backing plate, gusset and support foot plate, the backing plate and link of boards, the link of boards stabilizer blade
Plate, the support foot plate are equipped with threaded connection hole.
Electrostatic cyclone provided by the invention, the beneficial effect is that: 1, air inlet is using the spiral case for rotating 180 °
Air inlet, the influence to internal gas flow is smaller, advantageously reduces interfering with each other for air-flow, substantially reduces the machine that short circuit occurs in air-flow
Meeting, strikes the large dust particle of tube wall after can effectively trapping into deduster inside, while can reduce 20%-30%
Resistance, shorten the mobile distance of particle, increase efficiency of dust collection；2, using contraction type exhaust pipe, lower end is by common straight tube
Formula is changed to contraction type, and this design neither influences efficiency of dust collection, and can reduce resistance, is suitable for separating thinner dust
Grain；3, the lower pipe end of contraction type exhaust pipe is concordant with the lower edge of the volute air-inlet mouth, can reduce the micro cyclone of annular space
Air-flow, the pressure loss are smaller；4, the high-efficiency dust remover that collection electrostatic technique and cyclone technology combine, electrostatic technique can be effective
It solves the problems, such as that dust of the single cyclone dust collectors for partial size less than 5 μm is not easy the drawback trapped, efficiency of dust collection is low, is removed with height
Dirt efficiency and the characteristics of be capable of handling high gas flow, the dust particles for partial size greater than 5 μm remove it using cyclonic principle
Dirt, and the dust for partial size less than 5 μm then uses electrostatic principle to its dedusting；And combine cyclone technology can be to avoid installation vibration
Deashing device is beaten, realizes automatic continuous deashing function using internal swirling eddy, reduces manufacturing cost, it is easy to maintenance, for electricity
Deduster overcomes back corona phenomenon to provide new approach, efficiently solves the problems, such as secondary fly-up；5, in the case of good seal, tool
There is higher efficiency of dust collection, it is advantageously ensured that air cleaner, meets environmental requirement.
