[0002] Oily fume pretreatment devices are indispensable facilities in waste gas treatment. All waste gas containing oily fumes is equipped with different types of pretreatment devices. These devices treat and remove oil, gas and dust from the oily fume to ensure the stable operation of the subsequent waste gas treatment system.

[0003] Existing oil fume pretreatment equipment uses spray equipment, activated carbon adsorption devices, or electrostatic capture equipment to adsorb impurities in the flue gas. However, when adsorbing different impurities, single filtration devices generally have problems such as low treatment efficiency, oil fume in the treated exhaust gas, which affects the treatment efficiency and service life of subsequent treatment facilities, poses safety hazards, and fails to meet emission standards.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A high-efficiency oily fume exhaust gas treatment device includes a support frame 8. An alkaline solution circulating water tank 7, which supplies alkaline solution to the device, is installed at the bottom of the support frame 8. A cyclone-mixing spray tank 3, which drives the device to spray, is installed on one side of the middle of the support frame 8. The cyclone-mixing spray tank 3 drives the alkaline solution to rotate and spray. An electrostatic adsorption box 4, connected to the cyclone-mixing spray tank 3, is installed at the upper end of the support frame 8. The electrostatic adsorption box 4 adsorbs and filters the exhaust gas. An alkaline washing spray pipe 1, located on the side of the support frame 8 between the electrostatic adsorption box 4 and the alkaline solution circulating water tank 7, is installed. The alkaline washing spray pipe 1 transports the alkaline solution. An oily fume exhaust gas inlet 2, located at the front end of the support frame 8 and on one side of the cyclone-mixing spray tank 3, transports the exhaust gas into the device. An oily fume exhaust gas outlet 5, located at the top of the support frame 8 and above the electrostatic adsorption box 4, discharges the treated gas. The oily fume exhaust gas outlet 5 discharges the exhaust gas.

[0022] refer to Figure 2The top end of the alkaline washing spray pipe 1 is connected to the cyclone mixing spray tank 3. A three-way valve 9 is installed at the top end of the alkaline washing spray pipe 1, and the other end of the three-way valve 9 is connected to the nozzle 10. The upper part of the alkaline washing spray pipe 1 is connected to the bottom end of the electrostatic adsorption box 4. The oily fume exhaust gas enters the support frame 8 through the oily fume exhaust gas inlet 2. The exhaust gas is cross-absorbed with the alkaline solution in the cyclone mixing spray tank 3 in a counter-current flow to remove the smoke and oil mist in the oily fume exhaust gas. The alkaline solution circulating water tank 7 supplies alkaline solution to the cyclone mixing spray tank 3 through the alkaline washing spray pipe 1. After the oily fume exhaust gas passes through this section, the cyclone mixing spray tank 3 sprays the exhaust gas through the nozzle 10. When the exhaust gas enters the interior of the electrostatic adsorption box 4 and is treated, the electrostatic adsorption box 4 adsorbs impurities. The three-way valve 9 is rotated, and the three-way valve 9 drives the liquid to pass through the alkaline washing spray pipe 1 to wash the impurities adhering inside the electrostatic adsorption box 4, thereby improving the cleanliness of the electrostatic adsorption box 4.

[0023] refer to Figure 3 and Figure 4 The electrostatic adsorption box 4 includes an adsorption box 41. Baffles 42, which limit the front and rear ends of the electrostatic adsorption equipment, are installed at the front and rear ends of the adsorption box 41. A cleaning brush 47 is movably sleeved inside the baffle 42. A connecting plate 45 is installed at one end of the cleaning brush 47. Screws 46, which control the extension and retraction of the connecting plate 45, are installed on both sides of the connecting plate 45. A gear 48 is installed at the rear end of the cleaning brush 47. A rack 49 is installed at the rear end of the baffle 42 and on one side of the gear 48. Impurities are adsorbed by the electrostatic collection plate 44. When the screws 46 are activated, the cleaning brush 47 moves up and down in a circular motion. At the same time, the other end of the cleaning brush 47 drives the gear 48 and the rack 49 to mesh. That is, when the cleaning brush 47 moves up and down, it can scrape off the impurities adhering to the surface of the electrostatic collection plate 44, thereby improving the efficiency of impurity removal.

[0024] refer to Figure 5 The electrostatic adsorption device includes an energized plate 43, with an electrostatic collecting plate 44 clamped inside the energized plate 43. A dust removal brush 47 is externally mounted and attached to the outside of the electrostatic collecting plate 44. The electrostatic collecting plate 44 drives the energized plate 43 to be installed inside the adsorption box 41, and the energized plate 43 supplies power to the device, causing an electric field to be formed between the two sets of electrostatic collecting plates 44. At the same time, when dust passes between the electrostatic collecting plates 44, the attraction generated by the electrostatic collecting plates 44 can adsorb and treat the dust.

[0025] refer to Figure 1The flue gas to be filtered is transported to the interior of the support frame 8 through the oil fume inlet 2. At the same time, the cyclone mixing spray tank 3 is in pre-contact with the flue gas. Simultaneously, the flue gas is transported to the interior of the electrostatic adsorption box 4 and discharged through the oil fume outlet 5. After the flue gas is transported to the interior of the equipment through the oil fume inlet 2, the cyclone mixing spray tank 3 drives the alkaline solution to rotate and spray through the alkaline washing spray pipe 1. That is, the exhaust gas and the alkaline solution are cross-absorbed in the cyclone mixing spray tank 3 in a counter-current flow to remove the flue gas and oil mist in the oil fume. At the same time, the treated flue gas is transported to the interior of the electrostatic adsorption box 4. The electrostatic adsorption box 4 adsorbs the impurities in the flue gas through electrostatic adsorption and discharges through the oil fume outlet 5.

[0026] refer to Figure 1 The electrostatic adsorption box 4 is provided with an electrostatic adsorption box inspection port 6 at the front end. An observation window is installed in the middle of the electrostatic adsorption box inspection port 6. The status of the electrostatic adsorption box 4 can be observed through the observation window. At the same time, the electrostatic adsorption box inspection port 6 can be replaced by opening it.

[0027] Working Principle: During operation, oily fumes enter the treatment equipment through the oily fume inlet 2. The fumes are then subjected to counter-current absorption by the alkaline solution in the cyclone mixing spray tank 3, removing fumes and oil mist. The alkaline solution in the circulating water tank 7 is supplied through the alkaline washing spray pipe 1. After this stage of treatment, the oily fumes enter the electrostatic adsorption box 4 at the top of the cyclone mixing spray tank 3. This box contains an electrostatic precipitator plate, which further purifies the oil mist, removing it from the fumes. The oily fumes are then discharged through the oily fume outlet 5 and enter subsequent waste gas treatment facilities. The alkaline solution used in the cyclone mixing spray tank 3 cleans the oil stains on the electrostatic precipitator plate's tungsten wire, facilitating further action to capture oil mist and purify the fumes. The electrostatic precipitator plate can be inspected and replaced through the electrostatic adsorption box inspection port 6.

[0028] 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 to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
