[0024] In order to better understand the present invention, the present invention is preferably described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 4 As shown, the present invention discloses an air film type high-efficiency dynamic centrifugal composite oil fume purifier 100, comprising a smoke hood 1, a solution chamber 2, a flow equalizing plate 3, a dynamic interception component 4, a fan 5 and an air pump 6; the solution chamber 2, the flow equalizing plate 3, the dynamic interception component 4, the fan 5 and the air pump 6 are arranged in the smoke hood 1; the solution chamber 2 is located at the bottom of the smoke hood 1, and the solution chamber 2 is filled with an active foaming solution; the flow equalizing plate 3 is arranged at the air inlet of the smoke hood 1; the dynamic interception component 4 is arranged behind the flow equalizing plate 3, for purifying the oil fume entering from the flow equalizing plate 3; the fan 5 is arranged on one side of the dynamic interception component 4, providing exhaust power for the oil fume purifier 100; the air pump 6 is arranged on the upper side of the interior of the smoke hood 1, providing gas to the solution chamber 2, so that the foaming solution generates bubbles on the dynamic interception component 4.

[0026] The oil fume purifier 100 of the present invention comprises a smoke hood 1, a solution chamber 2, a flow balancing plate 3, a dynamic interception component 4, a fan 5 and an air pump 6. The smoke hood 1 is arranged on the outer surface of the oil fume purifier 100 to form a shell. The solution chamber 2, the flow balancing plate 3, the dynamic interception component 4, the fan 5 and the air pump 6 are arranged inside the smoke hood 1. The solution chamber 2 is located at the bottom of the smoke hood 1. The solution chamber 2 is filled with a foaming solution. The air pump 6 is arranged in the smoke hood 1 to provide gas to the solution chamber 2, so that the foaming solution in the solution chamber 2 generates bubbles. The bubbles are transported to the dynamic interception component 4, which breaks the bubbles and converts them into water films that are adsorbed on the dynamic interception component 4. At the same time, the oil smoke entering from the equalizing plate 3 is intercepted by the dynamic interception component 4 to intercept the grease and particulate matter. The water film adsorbed on the dynamic interception component 4 is mixed with the grease and particulate matter. The centrifugal force of the dynamic interception component 4 throws out the mixture of water film, grease and particulate matter, thereby achieving the effect of purifying the oil smoke and cleaning the dynamic interception component 4. The purified smoke is extracted by the fan 5, thereby completing the effect of purifying and exhausting smoke. The fan 5 provides exhaust force in the smoke hood 1, and the equalizing plate 3 is used to adjust the oil smoke entering the smoke hood 1 so that the oil smoke enters the smoke hood 1 evenly, so that the dynamic interception component 4 in the smoke hood 1 can purify the oil smoke evenly.

[0027] Among them, the air pump 6 includes a foaming tube 61 and an air pipe 62. The foaming tube 61 is arranged in the solution chamber 2. One end of the air pipe 62 is connected to the air pump 6, and the other end is connected to the foaming tube 61. The solution chamber 2 also includes a bubble spraying tube 24. One end of the bubble spraying tube 24 is connected to the solution chamber 2, and the other end is close to the center of the dynamic interception component 4. In order to generate bubbles in the foaming solution in the solution chamber 2, the air pump 6 is connected to the air pipe 62, and a foaming tube 61 is arranged in the solution chamber 2. The foaming tube 61 is connected to the air pipe 62, and the gas provided by the air pump 6 is filled into the foaming tube 61. The surface of the foaming tube 61 is provided with fine air outlets. The gas is discharged into the solution chamber 2 through the air outlets. The foaming solution produces a large number of bubble films with a diameter of 1.5mm-3mm. A large number of bubble films are continuously sprayed from the bubble spraying tube 24 on the solution chamber 2 to the center of the dynamic interception component 4, through the dynamic The dynamic interception component 4 is hit at high speed and broken into a water film. Under the action of centrifugal force, the air film flows from the center to the surrounding area and adheres to the surface of the dynamic interception component 4. The surface of the mesh is stably covered with an active water film for a long time. Since the dynamic interception component 4 rotates at a high speed of 2500-3000r / min, and a large amount of water film is attached to the surface of each mesh of the dynamic interception component 4, and contains a large amount of active ingredients, the surface tension of the bubbles is reduced, and the adsorption amount and efficiency of the air film are greatly enhanced; the surface area of ​​the water film mesh * number of revolutions * time = total purification efficiency.

[0028] The smoke hood 1 of the present invention includes a bubble partition plate 11, a first partition plate 12, a second partition plate 13 and multiple third partition plates 14; the bubble partition plate 11 is arranged above the solution chamber 2, and the bubble partition plate 11 and the smoke hood 1 form a solution chamber 2; a first chamber 15 is formed between the first partition plate 12, the dynamic interception component 4, the bubble partition plate 11 and the smoke hood 1, and the first chamber 15 is located above the solution chamber 2; a second chamber 16 is formed between the first partition plate 12, the dynamic interception component 4, the second partition plate 13 and the smoke hood 1, and the second chamber 16 is located above the first chamber 15; the second partition plate 13, the smoke hood 1 and multiple third partition plates 14 form a left chamber 17 and a right chamber 18, and the left chamber 17 and the right chamber 18 are arranged above the second chamber 16, and the air pump 6 is located in the right chamber 18.

[0029] The dynamic interception assembly 4 further includes an air guide 41 and an oil guide cover 42. The air guide 41 is disposed below the dynamic interception assembly 4 and is used to connect the first chamber 15 and the second chamber 16. The oil guide cover 42 is disposed on the periphery of the air guide 41 and is used to intercept grease thrown out of the dynamic interception assembly 4. An oil drain port 7 is disposed at the bottom of the oil guide cover 42, and the oil drain port 7 is disposed corresponding to the return plate 21. The solution chamber 2 includes a return plate 21, which is disposed above the right side of the solution chamber 2 and is provided with a return hole 22. The return plate 21 is used to receive the mixture of smoke oil and foaming solution thrown out of the dynamic interception assembly 4.

[0030] In order to discharge the mixture of water film, grease and particulate matter thrown out by the dynamic interception component 4, an oil guide cover 42 and an air guide tube 41 are set on the periphery of the dynamic interception component 4. The air guide tube 41 is used to pass the oil smoke. The oil guide cover 42 surrounds the air guide tube 41. The smoke contains a large amount of grease, particulate matter and VOC gas. After the oil smoke flow plate 3 enters the smoke collecting hood 1, when the smoke passes through the dynamic interception component 4, the grease in the smoke is effectively impacted and intercepted, changing the direction of the particles. At the same time, it is thrown into the oil guide cover 42 by centrifugal force, so that the oil smoke dry particles with smaller particle size are caught by the mesh surface. The active water film collides and adheres with the sticky particles, and at the same time, they are thrown into the oil guide cover 42 by centrifugal force; most of the VOC gases in the oil smoke are hydrophilic gases, which are intercepted and adsorbed by the active water film on the mesh, and at the same time, they are thrown into the oil guide cover 42 by centrifugal force. An oil drain hole 43 is provided under the oil guide cover 42, and the mixture of water film, grease and particles flows to the return plate 21 through the oil drain hole 43. The return plate 21 guides the mixture of water film, grease and particles to the reflux hole 22, and flows into the solution chamber 2 through the reflux hole 22 for separation and storage.

[0031] After the mixture of water film, grease and particulate matter flows into the solution chamber 2, the mixture of water film, grease and particulate matter is separated by the oil-water separation component 23 arranged in the solution chamber 2. The oil-water separation component 23 is arranged in the solution chamber 2; the oil-water separation component 23 includes an oil separator 231, a slag separator 232 and a liquid separator 233.

An oil storage chamber 234 is arranged between the oil separator 231 and the solution chamber 2. The oil storage chamber 234 stores grease. The reflux hole 22 is arranged above the oil storage chamber 234. The grease and particulate matter are separated in the oil storage chamber 234 through the oil separator 231, the slag separator 232 and the liquid separator 233. The grease floats to the top of the solution, the particulate matter settles to the bottom of the cavity, and the solution flows back to the right side of the solution chamber 2 for reuse.

[0032] The oil fume purifier 100 also includes an oil drain port 7 and a liquid drain port 8; the oil drain port 7 is arranged at the bottom of the solution chamber 2 and is connected to the oil storage chamber 234. After the oil in the oil storage chamber 234 is filled with oil, the oil is discharged through the oil drain port 7; the liquid drain port 8 is arranged at the bottom of the solution chamber 2. When the solution in the solution chamber 2 loses its activity and stops foaming, the inactivated foaming solution is discharged through the liquid drain port 8.

[0033] Furthermore, the smoke hood 1 includes a fan access panel 19, which is arranged above the second chamber 16 and is connected to the outlet of the fan 5. A fan 5 access port is provided on the side of the fan 5 to facilitate maintenance of the fan 5 in the smoke hood 1.

[0034] The oil fume purifier 100 also includes an electrical control box 9, which is arranged at the front end of the fume hood 1. The electrical control box 9 includes multiple control switches 91 and multiple lighting lamps 92. The control switches 91 are arranged on the electrical control box 9, located on the side of the electrical control box 9 away from the fume hood 1; the lighting lamps 92 are arranged at the bottom of the electrical control box 9 to illuminate the oil fume purifier 100 when it is in use.

[0035] To sum up, the solution chamber 2 of the present invention is provided with an oil-water separation component 23, which reduces the frequency of solution replacement and reduces the user's usage cost; the air film generated by the solution with active decontamination ingredients is intercepted by the dynamic interception component 4, and the grease and particulate matter on the dynamic interception component 4 are also adhered and adsorbed and then fall off by centrifugal force, which greatly reduces the cleaning frequency of the equipment; at the same time, the oil fume purifier 100 of the present invention has an efficient fire prevention function, and the high speed of the dynamic interception component 4 can shield the flames. The efficient purification efficiency makes the smoke hood 1 have no obvious oil stains during long-term use, and there is no oil in the flue and no secondary combustion materials; the cleaning frequency of the fan 5 in the smoke hood 1 is reduced, the exhaust system is fully protected, and the fan 5 can achieve a stable exhaust effect for a long time; and the efficient purification makes the three pollutants meet the emission standards in a long-term and stable manner, thereby realizing that small-scale catering, residential catering, and night market catering can meet the emission standards without disturbing the public with oil smoke, effectively promoting the development of food culture to food economy.
