Detailed Implementation

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-7 As shown, a purification device for treating spray painting exhaust gas includes a bottom tank 1 and a circulating water supply device 2. A vertical cabinet 3 is mounted on the bottom tank 1. The front of the vertical cabinet 3 is an open structure, and a horizontally arranged water tank 4 is provided on the upper front part of the vertical cabinet 3. The water tank 4 is connected to a water curtain plate 5, which extends to the opening of the bottom tank 1. After water is supplied to the water tank 4, the water overflows from the top of the water tank 4, flows down along the water curtain plate 5, and drips into the bottom tank 1, forming a water curtain between the water curtain plate 5 and the bottom tank 1.

[0024] A duct 6 is provided on the back of the water curtain plate 5. A detachable cyclone panel 61 is installed at the bottom of the duct 6. The cyclone panel 61 includes a sleeve 611 that fits onto the duct 6. A locking mechanism 63 is provided between the sleeve 611 and the duct 6, which allows the sleeve 611 to be detached from the duct 6. There are two locking mechanisms 63, distributed on both sides of the duct 6. Each locking mechanism 63 includes a latching member 631 fixed to the side wall of the duct 6. A lever 632 is hinged to the sleeve 611. The lever 632 is connected to a matching buckle member 633. By levering the lever 632, the buckle member 633 can be engaged with or disengaged from the latching member 631, thus locking or unlocking. A water-receiving plate 612 is provided at the center of the sleeve 611. Multiple inclined guide vanes 613 are connected between the water-receiving plate 612 and the sleeve 611. The guide vanes 613 are blade-shaped. The guide vanes 613 can make the gas passing through the cyclone panel 61 form a cyclone.

[0025] Inside the air duct 6, there is a water spray pipe 62 directly opposite the center of the cyclone panel 61. After water is introduced into the water spray pipe 62, water droplets fall into the center of the cyclone panel 61. At least two air ducts 6 are installed, evenly arranged in a row to enhance purification capacity. A water vapor filtration device 7 is installed above the air duct 6. The water vapor filtration device 7 includes a water vapor separator, a filter cotton layer, and an activated carbon layer arranged sequentially from bottom to top, which can perform water vapor separation and further filter the passing gas.

[0026] The water vapor filtering device 7 is provided with an air extractor 8. The air extractor 8 performs air extraction, so that the spraying exhaust gas enters the cyclone panel 61 through the gap between the water curtain panel 5 and the bottom groove 1, and then passes through the air cylinder 6 and the water vapor filtering device 7 in sequence and is taken out by the air extractor 8. After the water pipe 62 is connected to water, the water drops into the center of the cyclone panel 61. Since the cyclone is formed at the cyclone panel 61, the water vapor mixture is formed in the air cylinder 6. The water combines with the spraying particles in the exhaust gas, and then drops from the cyclone panel 61, thereby playing a role of purifying the spraying exhaust gas.

[0027] The bottom groove 1 is provided with a water receiving area 11, a sedimentation area 12 and a water returning area 13 connected in sequence. The bottom surface of the water receiving area 11 is inclined, and the inclined surface is inclined downward from the front side to the side of the sedimentation area 12, so as to facilitate the flow of sewage in the water receiving area 11 to the sedimentation area 12. The upper portion of the water receiving area 11 is provided with a water receiving plate 14 extending from the lower portion of the water curtain panel 5 to the edge of the sedimentation area 12. The water receiving plate 14 is provided with a convex wall 15 separating the water curtain panel 5 and the water droplets of the cyclone panel 61. The convex wall 15 separates the sewage droplets of the water curtain panel 5 and the cyclone panel 61. The sewage droplets of the water curtain panel 5 are guided into the water receiving area 11, and the sewage droplets of the cyclone panel 61 fall on the water receiving plate 14. The water receiving plate 14 can directly guide the sewage at this position into the sedimentation area 12, so as to avoid the mixing of the sewage into the water receiving area 11 and the stirring of the water in the water receiving area 11 and the mixing of too much sewage, which affects the water circulation effect. The cross section of the convex wall 15 is triangular, and the convex wall and the water receiving plate 14 are integrally bent from the plate material, so as to facilitate the production and manufacturing.

[0028] The sedimentation area 12 and the water returning area 13 are provided with a filter screen 16. The filter screen 16 is provided with two overlapping filter screens. The inner walls of the two sides of the bottom groove 1 are provided with insertion grooves. The two ends of the filter screen 16 are respectively inserted into the insertion grooves, so as to facilitate the replacement of the filter screen 16. When one of the filter screens 16 accumulates a certain amount of sediment, it can be extracted and replaced with a new filter screen 16. The other filter screen 16 can also continuously filter when it is replaced.

[0029] The circulating water supply device 2 is communicated with the water tank 4 and the water pipe 62, so as to supply water to the water tank 4 and the water pipe 62. The circulating water supply device 2 comprises a water pump 21 located in the water returning area 13. The water pump 21 is connected with a water supply pipe 22 connected to the water tank 4 and the water pipe 62. The water pump 21 circulates the water in the water returning area 11 into the water tank 4 and the water pipe 62.

[0030] The above embodiment is a preferred implementation manner of the utility model, and is not a limitation on the utility model. Any obvious replacement without departing from the utility model concept is within the protection scope of the utility model.
