[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a technical solution: an electrostatic oil fume purification device with a cleaning function, comprising: a filter box 1, which is a cavity with openings at both ends; a spray section located on one side inside the filter box 1, the spray section including a spray pipe 4 fixedly connected inside the filter box 1, and a partition fixedly connected inside the filter box 1 for separating the air flow path and forming a water curtain to reduce dust; a heat exchange section located in the middle of the filter box 1, the heat exchange section including a spiral heat exchange tube 9 located inside the filter box 1; and a dust removal box 2 fixedly connected to one end of the filter box 1 and communicating with the filter box 1, the dust removal box 2 having multiple sets of electrode plate assemblies 16 for electrostatic oil fume removal installed inside, and a high-pressure nozzle 15 for cleaning the electrode plate assemblies 16 installed on the side of the filter box 1 corresponding to the position of the electrode plate assemblies 16.

[0023] It should be noted that in this embodiment, a controller and a corresponding operation panel are provided to control various electrical appliances. The exhaust end of the filter box 1 is connected to the dust collection box 2, and an anti-cross-flow air valve is installed at the air inlet end of the filter box 1. The exhaust gas from the setting machine enters the interior of the filter box 1 through the air inlet end. Inside, it is purified, de-haired, de-particulate, and de-oiled by a spray section. Then, the air is expelled by the heat exchange section, where cold water and air exchange heat. The hot water is discharged to the insulation box for heat preservation. The interior of the filter box 1 is equipped with cleaning nozzles for the top and bottom of the spiral heat exchange tube 9, used to rinse the tube and reduce the efficiency of manual cleaning. After heat exchange, the air enters the interior of the dust collection box 2. The electrode plate assembly consists of positive and negative electrodes and generates an electric field through voltage. When the oil fume enters the dust collection box, the oil fume particles are acted upon by the electric field, causing the particles (such as oil mist and particulate matter) in the oil fume to become electrostatically charged. The charged oil fume particles are attracted to the electrode plates with the opposite charge. Similar to electrostatic adsorption, it can effectively capture and filter out oil fume particles in the air. The purified air is discharged from the top. When cleaning the electrode plate assembly 16 regularly, the water pump 12 sprays high-pressure water through the high-pressure nozzle 15. Multiple high-pressure nozzles 15 are used to rinse the electrode plate assembly 16, thereby reducing the number of times manual cleaning is required.

[0024] In one embodiment, the system further includes an oil-water separator 3, with a water pump 12 fixedly connected to the outlet end of the oil-water separator 3, and a water delivery pipe 19 fixedly connected to the output end of the water pump 12. The water delivery pipe 19 is connected to the spray pipe 4 and the high-pressure nozzle 15. A water collection tank 7 is fixedly connected to the bottom of the filter box 1, and a water collection pipe 17 is fixedly connected to one side of the water collection tank 7. A water collection pipe 2 is fixedly connected to one side of the bottom of the dust collector 2, and the water collection pipe 2 and the water collection pipe 17 are connected to the liquid inlet of the oil-water separator 3.

[0025] It should be noted that the structure of the oil-water separator 3 in this embodiment adopts an existing configuration scheme, please refer to the patent document with patent number 202020723995.5 for details. The water sprayed inside the filter box 1 and the cleaned water inside the dust removal box 2 enter the water collection tank 7 and are discharged into the oil-water separator 3 through water collection pipe 17 and water collection pipe 18. The oil-water separator 3 separates the oil and water. After filtration, the water is pumped by the water pump 12 and sent back into the spray pipe 4 through the water supply pipe 19 for recycling. An electromagnetic reversing valve is installed in the middle of the water supply pipe 19 to switch the water supply path between the spray pipe 4 and the high-pressure nozzle 15.

[0026] In one embodiment, the partition includes an inclined plate 5 and a partition plate 6 that are fixedly connected alternately inside the filter box 1. The inclined plate 5 is fixedly connected at an angle to the top inside the filter box 1 to form a water curtain.

[0027] It should be noted that in this embodiment, the inclined plate 5 and the partition plate 6 separate the space inside the filter box 1. After the air is sprayed by the spray pipe 4, it passes through the bottom of the inclined plate 5. The spray pipe 4 sprays water into the top of the inclined plate 5 so that it flows down along the inclined surface of the inclined plate 5 to form a water curtain. The air passes through the water curtain for filtration. Then the air passes out from the top of the partition plate 6 and enters the bottom of the baffle 8. In this way, the air can be sprayed.

[0028] In one embodiment, a baffle 8 for blocking water mist is installed inside the filter box 1, a baffle 10 is fixed to the bottom of the inner wall of the filter box 1, a spiral heat exchange tube 9 is installed on both sides of the baffle 10, a ventilation space is provided between the top of the baffle 10 and the filter box 1, and a fiberglass demister 11 is fixed to one end of the filter box 1.

[0029] It should be noted that in this embodiment, the air, after being washed by water, bypasses the bottom of baffle 8 and comes into contact with the spiral heat exchange tube 9. The bottom of baffle 10 is fixed to the bottom of the inner wall of the filter box 1, thereby separating the spiral heat exchange tubes 9 on both sides. This allows the air to pass between baffle 8 and baffle 10 and then exit from one side of baffle 10. During this process, a corresponding pump inputs cold water from one end of the spiral heat exchange tube 9. After exchanging heat with the air through the spiral heat exchange tube 9, the water is discharged from the other end. This process can cool the air through heat exchange and also condense and dehumidify it. The air blows past the outside of the spiral heat exchange tube 9 and comes into contact with the fiberglass demister 11, which performs a demisting operation on the air.

[0030] In one embodiment, an exhaust pipe 14 is fixedly connected to the top of the dust collection box 2, and a fan 13 is fixedly connected to one end of the exhaust pipe 14.

[0031] It should be noted that in this embodiment, the fan 13 input end draws air from the inside of the dust collector 2 through the exhaust pipe 14, thereby removing negative pressure from the inside of the dust collector 2, so as to facilitate the introduction of air from the filter box 1 into the dust collector 2, and then discharge it through the output end of the fan 13.
