[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-3 The utility model provides a technical solution: a wet fume purification device, comprising a fume hood 1, a connecting shell 2 connected to the top of the fume hood 1, and an exhaust box 3 connected to the top of the connecting shell 2 and having an exhaust fan integrated therein, wherein a smoke exhaust hole is provided in the middle of the plate between the fume hood 1 and the connecting shell 2. A water tank 1.1 is provided horizontally at the bottom end of the rear wall of the inner cavity of the fume hood 1, a water inlet joint 1.4 is provided at the top end of the front wall of the water tank 1.1, and a water replenishment valve 1.2 and a drain valve 1.3 are provided at the top and bottom ends of the rear wall of the water tank 1.1, respectively.

[0029] The purification cylinder 7 comprises a cylinder 7.1 whose top end is fixed to the hole in the middle of the top surface of the inner cavity of the smoke hood 1, an inverted truncated cone-shaped shell 7.2 whose top end is fixed to the top of the inner circumferential wall of the cylinder 7.1, a spherical shell 7.3 connected to the bottom end of the cylinder 7.1 and a sewage discharge joint 7.4 fitted on the bottom end of the spherical shell 7.3. A plurality of smoke inlet holes 7.1.1 are arranged on the top of the side wall of the cylinder 7.1 along the circumferential direction, and a plug hole 7.1.2 is arranged on the side wall of the cylinder 7.1 near the bottom.

[0030] The spray pipe 6 is arranged vertically at the center of the inner cavity of the cylinder 7.1, and a plurality of spray micro holes are arranged on the outer wall of the top of the spray pipe 6 along the circumferential direction.

[0031] The water inlet pipe 5 is fixedly sleeved in the socket 7.1.2, and the inner end of the water inlet pipe 5 is connected to the bottom end of the spray pipe 6. Since the water inlet pipe 5 is a stainless steel pipe, the spray pipe 6 is fixedly supported.

[0032] The water pump 4 is fixed to the rear wall of the inner cavity of the smoke collecting hood 1, and the outer end of the water inlet pipe 5 is connected to the output end of the water pump 4. The input end of the water pump 4 extends to the bottom of the inner cavity of the water tank 1.1.

[0033] The water mist filter 8 is detachably mounted on the top of the cylinder 7.1, and is used to intercept the water vapor in the smoke discharged upward from the inner cavity of the cylinder 7.1. The water mist filter 8 includes a frame 8.1 and a stainless steel mesh inserted through a rectangular hole at the bottom end of the side wall of the connecting shell 2. The front wall of the frame 8.1 is evenly provided with a plurality of strip slots 8.1.1 extending in the horizontal direction and used to insert the stainless steel mesh. The stainless steel mesh is 200 to 500 meshes.

[0034] The input end of the drain pipe 10 is connected to the sewage discharge joint 7.4, and the output end of the drain pipe 10 is connected to the water inlet joint 1.4.

[0035] In summary, when in use, the smoke exhaust fan in the inner cavity of the exhaust box 3 is turned on, so that negative pressure is formed in the cylinder 7.1, so that the oil smoke enters the inner cavity of the smoke hood 1 through the air intake grille on the smoke hood 1, and enters the inner cavity of the cylinder 7.1 through the smoke inlet hole 7.1.1.

[0036] The water pump 4 draws clean water from the water tank 1.1 and pumps it into the spray pipe 6 through the water inlet pipe 5. The top of the spray pipe 6 sprays water mist to all sides. The water mist fully captures the oil particles in the oil smoke. The water droplets with the oil smoke particles fall into the spherical shell 7.3 and flow back to the water tank 1.1 through the sewage connection 7.4, the drainage pipe 10, and the water inlet connection 1.4 in sequence, forming a water circulation system.

[0037] In addition, the flue gas containing water mist continues to be discharged upward. When passing through the water mist filter 8, the multi-layer stainless steel mesh intercepts the water vapor in the flue gas, thereby removing the oil in the flue gas to a large extent, improving the oil fume purification effect, and avoiding the accumulation of oil stains on the inner wall of the subsequent exhaust pipe.

[0038] The two side walls of the inner cavity of the frame 8.1 are provided with sliding grooves 8.1.2 for sliding engagement with the two sides of the stainless steel mesh, and the rear wall of the inner cavity of the frame 8.1 is provided with supporting grooves 8.1.3 for supporting the rear end of the stainless steel mesh at positions corresponding to the strip slots 8.1.1. The outer side wall of the frame 8.1 is fixed with an end plate 8.2, and the outer edge of the end plate 8.2 is fixed to the side wall of the connection housing 2 by screws.

[0039] A grid frame 1.5 is fixed at the front end of the inner cavity of the water tank 1.1, and a sponge 9 is arranged in the grid frame 1.5. The sponge 9 is an oleophilic and hydrophobic sponge, that is, the sponge 9 absorbs and purifies the oil in the oily wastewater refluxed from the inner cavity of the cylinder 7.
