Similar or identical parts are denoted by the same reference numerals in the drawings and descriptions. In actual applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in the present invention are intended only to illustrate the present invention and are not intended to limit its scope. Any obvious modifications or variations to the present invention do not depart from the spirit and scope of the present invention.

[0026] Example 1

[0027] See also Figures 1 to 5 In one embodiment of the present invention, a restaurant cooking fume exhaust gas treatment device includes a first treatment box 1, a second treatment box 2, and a third treatment box 3, which are fixedly installed in sequence, and the first treatment box 1, the second treatment box 2, and the third treatment box 3 are internally connected to each other. An air inlet 4 is provided on the side of the first treatment box 1, and an exhaust fan 5 is provided on the top of the third treatment box 3. After entering the first treatment box 1 through the air inlet 4, the cooking fume exhaust gas passes through the second treatment box 2 and the third treatment box 3 in sequence for purification treatment, and is finally discharged from the device through the exhaust fan 5.

[0028] A reduction motor 6 is fixedly mounted on the bottom end of the first treatment box 1, and a rotating plate 7 is fixedly mounted on the top end of the output shaft of the reduction motor 6. A protrusion 8 is provided on the side of the rotating plate 7, and a groove 9 that matches the protrusion 8 is provided on the inner wall of the first treatment box 1. Three annular clamping plates 10 are fixedly mounted on the upper end of the rotating plate 7, and an oil fume filter layer 11 and an activated carbon filter layer 12 are clamped between two adjacent annular clamping plates 10, respectively. The oil fume filter layer 11 and the activated carbon filter layer 12 are both cylindrical, and the activated carbon filter layer 12 is placed inside the oil fume filter layer 11. An air supply pipe 13 is provided on the top of the first treatment box 1. After the oil fume exhaust gas enters the first treatment box 1 through the air inlet 4, it first passes through the oil fume filter layer 11, and then passes through the activated carbon filter layer 12 before being discharged from the air supply pipe 13 at the upper end of the first treatment box 1. By driving the rotating plate 7 to rotate through the reduction motor 6, the oil fume filter layer 11 and the activated carbon filter layer 12 can be rotated synchronously, so that after the oil fume exhaust gas enters the interior of the first treatment box 1, it enters evenly from the periphery of the oil fume filter layer 11, avoiding the oil fume exhaust gas from entering the oil fume filter layer 11 from a fixed point, resulting in excessive accumulation of oil fume impurities at this fixed point, which affects the subsequent treatment effect.

[0029] The second treatment box 2 and the first treatment box 1 are connected through an air pipe 13. The oil fume exhaust gas is initially filtered and purified by the first treatment box 1 and then enters the second treatment box 2 through the air pipe 13. An annular spraying member 14 is provided at the top of the interior of the second treatment box 2. The annular spraying member 14 includes an annular water outlet pipe fixedly mounted on the inner wall of the second treatment box 2 and water outlet nozzles evenly distributed at the bottom of the annular water outlet pipe. An annular guide block 15 is fixedly provided on the side wall below the annular spraying member 14 inside the second treatment box 2. The annular guide block 15 divides the interior of the second treatment box 2 into a spray chamber and a reflux chamber from top to bottom. A water pump 16 is provided inside the reflux chamber. A reflux pipe 17 is provided on the rear outer wall of the second treatment box 2. One end of the reflux pipe 17 passes through the side wall of the second treatment box 2 and is connected to the annular water outlet pipe of the annular spraying member 14. The other end of the reflux pipe 17 passes through the side wall of the second treatment box 2 and is connected to the water pump 16. A filter frame 18 is fixedly provided on the outside of the water pump 16. After the oil fume exhaust gas enters the second treatment box 2, the annular spray part 14 sprays water mist to merge with the oil fume exhaust gas, so that the spray water carries particulate impurities and falls into the reflux chamber. The water falling into the reflux chamber can be returned to the annular spray part 14 for recycling through the water pump 16 and the reflux pipe 17. The impurities carried in the exhaust gas after spraying treatment can be removed through the filter frame 18, so that the water pumped in by the water pump 16 does not contain impurities, avoiding clogging of the reflux pipe 17 and the annular spray part 14. The second treatment box 2 is provided with an air vent 19 on the side wall at the upper end of the annular guide block 15, and a baffle 20 is provided around the air vent 19. The exhaust gas after spraying treatment inside the second treatment box 2 can be discharged from the box body through the air vent 19. The setting of the baffle 20 can prevent the spray water inside the second treatment box 2 from entering the air vent 19.

[0030] An air inlet 21 is provided on the side wall of the third treatment box 3, and the air inlet 21 is connected to the air vent 19 on the side wall of the second treatment box 2. A plurality of grid plates 22 are fixedly installed on the inner wall of the third treatment box 3 above the air inlet 21, and a first biological filler 23 and a second biological filler 24 are respectively filled between two adjacent grid plates 22. An air outlet pipe 25 is provided on the top of the third treatment box 3, and the other end of the air outlet pipe 25 is fixedly connected to the exhaust fan 5. After the oil fume exhaust gas enters the third treatment box 3 through the air inlet 21, it passes through the first biological filler 23 and the second biological filler 24 between the grid plates 22 in turn for deodorization treatment, and is finally discharged from the device through the air outlet pipe 25 and the exhaust fan 5. At this point, the oil fume exhaust gas has undergone multiple filtration, adsorption and deodorization treatments, and the treatment effect is better.

[0031] Example 2

[0032] See also Figures 6-7 On the basis of Example 1, a cover plate 26 is provided on the top of the first treatment box 1. Threaded holes 27 are provided around the cover plate 26 and around the top of the first treatment box 1. The cover plate 26 and the first treatment box 1 are movably connected through the threaded holes 27 and the studs 28. A lower flange 29 is fixedly installed on the top of the cover plate 26, and an upper flange 30 is fixedly connected to one end of the gas pipe 13. The upper flange 30 and the lower flange 29 are detachably connected by screws 31. A handle 32 is fixedly provided on the upper end of the cover plate 26, and the other end of the gas pipe 13 is rotatably mounted on the top of the second treatment box 2 via a bearing 33. By removing the upper flange 30 and rotating the bearing 33 and the gas pipe 13, the upper flange 30 can be rotated away from the cover plate 26. At this time, the cover plate 26 can be removed again, so that the oil fume filter layer 11 and the activated carbon filter layer 12 clamped inside the first treatment box 1 can be replaced. The device is easy to use, has stronger performance, and better effects.
