Purification process:
When motor 2 does not start, the rotating shaft of motor 2, band electric axis 11, conductive ring 15 are motionless, and one end combined electrical polar curve 14 be fixed on conductive ring 15 is in the state of naturally drooping (all not charged) under Gravitative Loads.After motor 4 starts, the rotating shaft of motor 2 drives band electric axis 11 high-speed rotation (can also high speed and low speed to hocket through shaft coupling 1, the rotating speed of described High Rotation Speed is that 600-100 turns/min, the rotating speed of described low speed rotation is that 100-500 turns/min, High Rotation Speed duration is 5-15s, low speed rotation duration is 50-100s), high-voltage power-line powers (4-10 ten thousand volts of voltages) through brush assembly of electric 6 to band electric axis 11 simultaneously, band electric axis 11 drives and rotates together with conductive ring 15, also the conductive disc 8 on conductive ring 15 is made to rotate together, High Rotation Speed makes the many combined electrical polar curves 14 originally naturally drooped open in umbrella under centrifugal action, umbrella electrostatic layer is formed under the effect of high-pressure electrostatic.Now the free end of combined electrical polar curve 14 still ensures with the Inner wall of cylindrical shell 3 gap being not less than 5cm.Because conductive ring 15, conductive disc 8 are conductor, if the high voltage source of therefore access is positive electricity, then the combined electrical polar curve 14 of rotation finally can be made with positive high voltage electrostatic, otherwise be then negative high voltage electrostatic; Owing to having two layers of electrostatic assembly in the present embodiment, therefore can form the umbrella electrostatic layer that two-layer difference is electrical, lower floor is negative high voltage electrostatic, upper strata is positive high voltage electrostatic, if electrostatic component be two-layer more than, then by that analogy, ensure that adjacent phase layer electrostatic component accesses electrically contrary.
The rotation of the band electric axis 11 in orlop electrostatic component also drives the rotation of air inducing impeller 10, air inlet 16 local is made to produce negative pressure, by the air (before purification gas) in the external world by air inlet 16 suction cylindrical shell 3, before purification, gas is entered in cylindrical shell 3 by air inlet 16 and is risen afterwards by the water smoke humidifying (described humidification degree is that the airflow humidity entering cylindrical shell is added to more than 90%) that water inflow nozzle 9 sprays, gas after humidifying is introduced into the umbrella electrostatic layer corresponding to lower floor's electrostatic component with negative high voltage electrostatic, when gas is through this umbrella electrostatic layer, bacterium is killed, part fine particle in gas and droplet charged, these were adsorbed by barrel by throwing to an inwall under centrifugal action that is charged and that originally produce at the combined electrical polar curve rotated with the droplet of negative electricity and fine particle major part, simultaneously, under high-pressure electrostatic effect, remainder in gas not by charged and originally with the fine particle of positive electricity and droplet be then attracted to combined electrical polar curve surface or its around, subsequently under the effect of the centrifugal force of combined electrical polar curve 14 generation rotated, glide after being thrown to an inwall after being adsorbed on combined electrical polar curve 14 surface or droplet around it and fine particle landing to the free end of combined electrical polar curve 14, finally, all dirt mud on barrel flow to mud dirt outlet 7 under the washing away of flushing water, and under high-pressure electrostatic effect, bacterium in gas is also effectively killed, on the other hand in the tangential direction, the fine particle/droplet in gas and the speed of related movement of combined electrical polar curve 14 are up to tens of rice to hundreds of rice, and its inertial collision effect is higher than common inertia demister tens times.So the fine particle/droplet in air-flow more easily strikes in spin line and is captured, consequently inertial dust collection/mist efficiency significantly promotes.Simultaneously, the combined electrical polar curve 14 of High Rotation Speed makes neighbouring gas also create rotary motion at a high speed, flow rotation speed is close to the speed of combined electrical polar curve 14, square being directly proportional, so the centrifugal force that the present invention produces is than common centrifugal dedusting/day with fog high hundreds of times of the centrifugal force and the rotary speed that produce due to swirling eddy.Certainly, the high velocity impact of combined electrical polar curve 14 and drop, likely smash drop and form thinner water smoke, but because litzendraht wire 14.1 has water sorption (capillarity), the drop bumping against combined electrical polar curve surface 14 can infiltrate litzendraht wire 14.1 inside, avoids drop and comes off for 14 2 times from the combined electrical polar curve surface of High Rotation Speed.In addition, the turbulence diffusion that combined electrical polar curve 14 produces is huge, and this turbulent diffusion effect is very beneficial for very thin mist vapour and fine particle is attached to combined electrical polar curve 14 surface and is captured.Liquid on combined electrical polar curve 14 gets rid of the internal face to cylindrical shell 3 along the free end of combined electrical polar curve 14 under centrifugal action, then glide along barrel, flushing water the washing away wall coordinating flooding nozzle 4 to spray, makes muddy water export 7 by mud dirt after mud guard 12 is collected and discharges;
After the umbrella electrostatic layer of lower floor, gas continues to rise and enters the umbrella electrostatic layer on upper strata, gas is when having the umbrella electrostatic layer of positive high voltage electrostatic through this, under the effect of positive high voltage electrostatic, in gas, the unsegregated fine particle with negative electrical charge and droplet are adsorbed to combined electrical polar curve 14 surface with positive high voltage electrostatic, its absorption and separation process same as above, make to be captured with the fine particle of negative electrical charge and droplet, throw to barrel and glide along barrel, exporting 7 by mud dirt after finally being collected by mud guard 12 and discharge.After two-layer charged opposite polarity umbrella electrostatic layer, the droplet in gas and fine particle major part separated, finally achieve gas cleaning be separated, purified gas continue rise discharged by the gas outlet 17 at top.
Experiment proves: the arresting efficiency of the present invention to the fine particle (pM2.5, pM10 and aerosol etc.) in gas reaches more than 60%, and demisting efficiency reaches more than 96%, and sterilization effect can reach more than 90%.
