3 enter region 2 402, enter region 4 404 along its bottom behind region 1 into region 1 along region 6 201
Bottom, gas, which passes through, enters region 5 405 from its top discharge along region 8 203 behind region 4 404, after from 5 405 bottom of region
Portion is discharged into region 3 403, and region 3 403 is connected to region 7 202, directly 1 row of air outlet from 7 202 top of region
Out；
It is equipped with water pump 1 in water tank 1, connects spray piping 11 on water pump 1, by water pump 1 by water tank 1
Interior water extraction is sent into region 1 and region 2 402 along spray piping 11, carries out spray process to gas；It is set in water tank 26
There is water pump 2 23, connect automatically cleaning pipeline 14 on water pump 2 23, is extracted the water in water tank 26 along automatically cleaning out by water pump 2 23
Pipeline 14 is sent into region 5 405, carries out cleaning treatment to electrostatic precipitation module；
Entire process flow is as follows:
After gas containing dust is from equipment air inlet 3 into spray bucket 1, due to special closed Duct design, so that
Air-flow can only move to from bottom to top spray bucket 1 from the bottom of spray bucket 1 and be connected to chamber with above spray bucket 2 33, i.e.,
Region 6 201 have passed through the once flushing of the water mist in spray bucket 1；Then, air-flow is after being connected to chamber, from spray bucket two
33 top enters, and passes through spray bucket 2 33, by the secondary flushing of the water mist in spray bucket 2 33；By this two
After road rinses, the big dust particles in air-flow in conjunction with water mist, fall to the bottom of uncovered water tank 4, and dust has obtained one
Secondary primary purifying is only left subtle particulate matter, at this point, airflow humidity increases very much；
Air-flow after spray is reached under unpowered tornado evaporator 20 by spraying the bottom air duct of bucket 2 33
Side is entered by the lower section of unpowered tornado evaporator 20, from bottom to top by unpowered tornado evaporator 20, air-flow out
Humidity is reduced to relative humidity 90% or so, and such air-flow enters electrostatic precipitation module, subtle powder using region 8 203
Dirt particle is constantly collected by the collecting plate of electrostatic field under the action of powerful high-voltage electrostatic field, leaves electrostatic precipitation module
Gas in dust collect clean by complete, be discharged through region 3 403 and region 7 202 along top outlet inlet 1 after
Equipment thereby realizes being fully cleaned up for dust；
Furthermore the air-flow of relative humidity 90% or so generates the negative oxygen ion beneficial to human body by electrostatic field energy, so that from
The air that air outlet comes out becomes especially pure and fresh.
It is (general when the Dust Capacity of collection reaches certain thickness since electrostatic precipitation module constantly collects dust particles
It is 8-10 hours), the dedusting module of electrostatic must be just rinsed, at this moment PLC control system is by blower and electrostatic precipitation mould
Block simultaneously closes off, and starts water pump 2 23, water flow flows into the spray head above electrostatic precipitation module by automatically cleaning pipeline 14, to quiet
Electric precipitation module is got express developed, and after 15s, flushing terminates, and at this moment blower is again started up, using air-flow to electrostatic precipitation module
It carries out strength to air-dry, the electrostatic precipitation module after air-drying, which is again turned on, to be worked normally.
The water that whole equipment uses is recirculated water, is pulled water out by water pump 1 and water pump 2 23 and carries out spray and cleaning
Reason, after return to uncovered water tank 4, uncovered water tank 4 is connected to water tank 1 and water tank 26 by waist-shaped hole 30, keep inside and outside water
Face height is consistent.
The bottom of uncovered water tank 4 is equipped with drain valve 9, arrives after a certain period of time in equipment work, by opening drain valve 9 come more
Water in exchange device.
One critically important parameter of dust is exactly the specific resistance value of dust, this parameter directly affects dust by electrostatic
The complexity of field absorption, dry dust specific resistance value is larger, so that dust is not easy after being collected by the collecting plate of electrostatic field
Charge-conduction is gone out, so that there is certain repulsive interaction to later dust, influences efficiency of dust collection；So being removed electrostatic is flowed into
The relative air humidity of dirt module maintains 90% or so, reduces the specific resistance value of dust, greatly improves efficiency of dust collection.
Influence of the relative air humidity to efficiency of dust collection known to following table:
| Relative humidity | 70% | 80% | 85% | 90% | 95% |
| Gas concentration (mg/m is discharged3) | 0.54 | 0.43 | 0.01 | 0.14 | 0.29 |
As seen from the above table, for relative air humidity when 85%, efficiency of dust collection highest, concentration is up to 0.02mg/m3,
Well below national normal value 0.6mg/m3；This list data is counted since 70%, because relative air humidity is too small, can be led
Dust specific resistance value is caused to increase, efficiency of dust collection is not high；Relative humidity is too big, will affect the absorption property of electrostatic field, efficiency of dust collection
Also not high, so the relative humidity between 75%-95% is taken to be compared, by data it is found that relative humidity 85%-90% it
Between efficiency of dust collection highest.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those skilled in the art within the technical scope disclosed by the invention, can without the variation that creative work is expected or
Replacement, should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be limited with claims
Subject to fixed protection scope.
