So, on the one hand can the heat in the fast transmission oil smoke waste gas reach the cooling effect, and on the other hand can reach good gas-carried liquid drop striking effect and form oil in water liquid drop, because oil in water liquid drop is electric charge, can be in the regional (dynamic adsorption plate 40) entrapment of rear end electrostatic adsorption.
Through combining atomizing nozzle subassembly and atomizing corona rotary part 30', can realize atomizing corona and produce plasma, contain free electron, active group in the plasma system, can effectively get rid of VOCs and foul gas pollutant.
The particle size of the fog drops sprayed by the atomizing nozzle is between 2 and 50 mu m, so that the sprayed fog drops are fine and uniform, and a better effect is realized.
The spray angle of the atomizing nozzle 34 is at an angle of 25-150 ° relative to the centerline of the housing 60. It can be understood that the spray angle, the spray pressure and the flow rate are adjusted according to the air volume of the treated oil fume waste gas, the spray angle is 25-150 degrees, and the optimal humidification and atomization effect is achieved.
It should be noted that the atomization nozzle assembly and the dynamic stranding cage (horizontal) discharge corona component are used for realizing atomization corona, and the atomization corona plasma technology has the technical advantages of both electrostatic deposition and plasma, so that the synergistic control of various pollutants in the oil fume waste gas can be realized.
The dynamic stranding cage (horizontal) discharge corona component includes a discharge electrode 33. The discharge electrode 33 generates negative corona discharge under the action of a negative high-voltage direct-current power supply. In the corona discharge process, the atomization water supply system continuously supplies water to the discharge electrode 33 through the atomization nozzle 34, so that an electrohydrodynamic atomization film is formed on the surface of the discharge electrode 33, and meanwhile, atomized water droplets are highly charged by free electrons and ions and fly to the shell 60 at a high speed under the action of an electric field to purify oil smoke and particulate matters. The atomization corona plasma technology has a wet electrostatic precipitation mechanism, and atomization corona discharge increases power coagulation of high-speed water drops, electrostatic coagulation of charged water drops, purification mechanisms such as electron charging of tiny dust and the like, so that the atomization corona plasma technology has higher removal efficiency on the tiny dust.
Because can continuously carry out discharge electrode 33 water supply atomizing, avoid oil droplet to glue dirty discharge electrode and the electrode that gathers dust, ensure that the device is stable for a long time and high-efficient operation, VOCs and elimination stink in the oil smoke can be got rid of to atomizing corona plasma. In addition, the atomized corona plasma can purify the circulating water at any time, and the sewage discharge is reduced to the maximum extent.
In the corona discharge process, air breakdown instantaneously generates plasma which contains free electrons, high-energy particles and active particles, wherein water mist can further react with the plasma to generate high-activity free radicals such as OH, O and the like and O 3 Isostrongly oxidizing molecules, highly active radicals such as OH, O and the like, and O 3 The equal strong oxidizing molecules can react with VOCs in the oil fume waste gas and gas phase molecules with stink odor to generate CO 2 、H 2 And O and other non-toxic harmless small molecular substances.
In use, the particle size of the soot particles to be purified (herein referred to as the first soot particles) is between 0.01-2 μm, and when the first soot particles in the soot exhaust gas pass through the electrocoagulation component 20, the first soot particles are electrically coagulated and agglomerated to form the second soot particles, and the particle size of the second soot particles is larger than that of the first soot particles.

The discharge electrode 33 can be made of burs, tungsten wires, molybdenum wires or stainless steel wires, and the like, and the discharge electrode 33 is corrugated and has a width of 5-15mm.
The discharge electrode 33 is laterally inclined at a predetermined angle with respect to the axis of the central shaft 31', and the discharge electrode is obliquely arranged with respect to the axis of the central shaft 31', specifically 10-80 degrees (e.g., 30-60 degrees), or 100-170 degrees (e.g., 120-150 degrees).
The central shaft 31 'is driven by a motor to rotate, so that the discharge electrode 33 is driven to rotate, a power-on tube is arranged in the central shaft 31', and a negative high-voltage direct-current power supply supplies power to the discharge electrode 33. The material of the discharge electrode 33 is preferably burs, because burs are used as the discharge electrode material, the corona onset voltage is low, and discharge points are densely distributed in various parts of the bur material. The prickle electrode can be made of at least one of bristles, nylon wires, steel wires and copper wires; the center shaft 31' may be made of at least one of iron wire and stainless steel wire, whereby a lower cost may be achieved.
The rotating speed of the discharge electrode 33 or the central shaft 31' is between 60 and 300r/min, and the corrugated discharge electrodes and the lateral inclined arrangement mode enable the gas to be treated to generate vortex in the central area of the discharge stranding cage (namely, the space formed by the rotation of the discharge electrode 33) in the high-speed rotation process of the discharge electrode 33. The vortex can improve oil smoke particulate matter electric charge probability on the one hand, on the other hand can make the less oil smoke particulate matter of particle size adhere each other and form the great oil smoke particulate matter of particle size, and under above-mentioned two aspects effect, oil smoke particulate matter purification efficiency can show and improve.

The rotating shaft 41 can be driven to rotate by an external driving device (such as a motor), and the adsorption pole plate 42 is driven to rotate by the rotating shaft, and the rotating speed is 500-1500r/min.
It will be appreciated that rotation of the discharge electrode 33 will cause a vortex in a certain direction, and for better treatment, it is preferable that the rotation direction of the rotating shaft 41 is set to be opposite to that, so that greater disturbance of the air flow can be achieved and the adsorption plate 42 can be exposed to a greater flow rate of the soot exhaust gas. Of course, the discharge electrode 33 and the adsorption plate 42 may be set to rotate clockwise or counterclockwise in the same direction, and their reverse rotation is not necessary, and those skilled in the art can select them according to actual needs.
