The water mist separating mechanism comprises a heat exchange tube 801, a condensation plate 802, a reflux plate 803 and an exhaust plate 804, wherein the heat exchange tube 801 is fixedly connected to the bottom of a lower connecting pipeline 403, the condensation plate 802 is slidably connected to the surface of the heat exchange tube 801, the reflux plate 803 is fixedly connected to the surface of the condensation plate 802, the exhaust plate 804 penetrates through the inner wall of the reflux plate 803, the surface of the exhaust plate 804 is provided with a reflux waist hole, the reflux plate 803 is obliquely arranged, the surface of the reflux plate 803 is fixedly connected with the inner wall of the cleaning tower 201, the reflux plate 803 is located above the spoiler 502, and water mist inside the cleaning tower 201 can be condensed conveniently by using cold water inside the water curtain groove 401.
In the installation process, an external filter device and an auxiliary filter liquid pump are installed between a liquid inlet pipeline 304 and a waste liquid pipeline 607, a tank cover plate 602 is opened, an electromagnetic valve 306 is closed, modified water is injected into a gas washing tank 601, then the auxiliary filter liquid pump of the external filter device is started to filter the modified water and then pump the filtered water into the modified water storage tank 302, so that the water level in the modified water storage tank 302 and the water level in the gas washing tank 601 reach a certain height, then the electromagnetic valve 306 is opened, a first liquid pump 308 is started, so that the pumping flow rate of the first liquid pump 308 is the same as that of the auxiliary filter liquid pump of the external filter device, the modified water in the modified water storage tank 302 is continuously pressurized and atomized from an atomization nozzle 311 and finally falls into the gas washing tank 601, the modified water in the gas washing tank 601 is continuously pumped and filtered from the waste liquid pipeline 607 and then returns to the modified water storage tank 302 from the liquid inlet pipeline 304, and thus circulation is formed, and an air inlet fan 107 in a paint spraying area is started, The exhaust fan 203 and the second liquid pump 404, the second liquid pump 404 continuously pumps the modified water in the spray booth 601 into the water curtain groove 401, then the modified water overflows from the overflow port 402 and flows downwards along the guide plate 407, thereby forming a water curtain on the surface of the guide plate 407, the downwards flowing water flows into the air guide hopper 603 through the paint spraying bearing plate 604 and finally flows back into the spray booth 601, the air inlet fan 107 in the paint spraying area supplements the processed air into the spray booth 103 during paint spraying, the exhaust fan 203 forms negative pressure to pump the paint mist generated in the spray booth 103 outwards, the paint mist firstly passes through the paint spraying bearing plate 604 and enters the air guide hopper 603, then enters the spray booth 601 and is discharged into the cleaning tower 201 from an exhaust gap on one side of the slag penetrating plate 701 along a gas washing channel between the modified water level and the tank cover plate 602, and at this time, the air guide hopper 603, A slotted cover 602, The venturi tube structure is formed between the slag penetrating plate 701 and the modified water page, paint mist is pressurized and accelerated to be sprayed upwards from the exhaust gap and is impacted with atomized modified water sprayed by the atomization spray nozzle 311, meanwhile, the paint mist is fully impacted with the liquid level of the modified water when passing through the gas washing channel, so that the paint mist is fully mixed with the modified water, oil or other fat is decomposed when meeting the modified water, grease pollutants are in a state of being easier to separate through saponification, the modified water can cut and disperse the grease pollutants through emulsification, so that the grease pollutants are easier to peel off, most pollutant ions have strong negative potential under the action of active hydrogen ions of the modified water, and meanwhile, a plurality of surfaces of objects to be cleaned also have negative charges, repulsive force is generated between the two, so that the paint mist has strong decontamination effect, in addition, the repulsive force can also prevent the surfaces of the objects to be cleaned from being polluted again, and the alkaline electrolyzed water contains abundant dissolved hydrogen, which has a certain effect on pollutant removal, the unabsorbed air and a small part of particle clusters rise along the cleaning tower 201, the rising mixture is firstly blocked by the spoiler 502 to flow back, the rest particle clusters are impacted and fall down, the air continuously passes through the ventilation plate 503 to rise after flowing back, the rising air is gradually cooled by the heat dissipation plate 202 in a heat conduction manner, so that part of water vapor is condensed and flows back, then the other air continuously rises, the rising air is blocked by the reflux plate 803 to flow back again, and is cooled again by the heat exchange tube 801 and cold water in the condensation plate 802, so that the water vapor is condensed and flows back again, then the air continuously rises to be filtered by the silk screen filter 204 and is fully intercepted, finally the water mist is dropped and flows back together with the modified water, the air passing through the wire mesh filter 204 is finally discharged.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
