On the side of the static pressure chamber 13 facing the operation chamber 1, explosion-proof lamps 15 are evenly arranged. The explosion-proof lamps 15 have the functions of lighting and alarming.

[0021] A water tank 4 is provided on the ground of the operation chamber 1. The bottom of the purification chamber 3 is communicated with the water tank 4. The operation chamber 1 and the purification chamber 3 are communicated through the water tank 4. A water pump 5 is equipped in the water tank 4. The water pump 5 is connected to a water supply pipe 10. The water supply pipe 10 is connected to a spiral nozzle 8. Below the spiral nozzle 8, three layers of water baffle plates 7 are provided in the purification chamber 3. The directions of every two adjacent layers of water baffle plates 7 are arranged in opposite directions so as to form layer upon layer of water curtains, enabling the air flow to pass through repeatedly and making the waste gas filtration efficiency more efficient; A water vapor filtration device 11 is provided at the top of the purification chamber 3. The water vapor filtration device 11 includes upper and lower frames, upper and lower baffle plates and hollow balls to intercept water vapor in the air and make the air flow dry; A suction fan is provided at the outlet of the water vapor filtration device 11 to discharge the filtered gas. The suction fan is protected by a suction hood 12. A closed door 6 is provided on one side of the purification chamber 3 to facilitate entry into the interior of the purification chamber 3 for maintenance.

[0022] A water curtain plate 17 is provided on the side of the purification chamber 3 facing the operation chamber 1. An overflow box 9 is provided above the water curtain plate 17. The water supply pipe 10 extends into the overflow box 9; The bottom of the water curtain plate 17 is connected with a serrated plate 18. The serrated plate 18 extends into the water tank 4 so that the water flow can flow into the water tank 4. The serrated plate 18 is serrated to ensure the coverage of the water curtain; A slag leakage box 21 is installed at the bottom of the purification chamber 3. The left side of the slag leakage box 21 is welded to the side plate of the water tank 4, and the right side is folded flat and installed with a water retaining adjusting plate 19. Uniform round holes are opened on the bottom plate of the slag leakage box 21. A water level pipe 22 is welded at the part of the bottom plate of the slag leakage box 21 where the round holes are opened so that the water flow in the purification chamber 3 can flow into the water tank 4 for water storage. The water storage level is preferably higher than the water outlet of the water level pipe 22 and lower than the bottom plate of the slag leakage box 21; The water retaining adjusting plate 19 is an arc-shaped plate. The upper end of the water retaining adjusting plate 19 is connected with a horizontal overlapping plate. The overlapping plate is flatly placed on the slag leakage box 21. The bottom is connected with a stainless steel folding rib 20 to vertically support the water retaining adjusting plate 19 in the water tank 4 to achieve a sealing effect. The overlapping plate can move horizontally on the slag leakage box 21 to adjust the position of the water retaining adjusting plate 19.

[0023] In this embodiment, since the operation chamber 1 is small and the length and width of the static pressure chamber 13 are the same as those of the operation chamber 1, the size of the static pressure chamber 13 can also be reasonably designed according to the actual size of the operation chamber 1 and the size of the operating table 2; The number of the water baffle plates 7 can be set according to the height of the purification chamber 3.

[0024] In this embodiment, a water tank 4 laid for a week is used for water storage. Alternatively, the floor of the operation room 1 can be made into a pool for water storage, and a platform is built above the pool for the use of the painting operation table 2.

[0025] The operation table 2 can be rotated to facilitate painting operations; a pre-operation table 2 can also be set in the area outside the operation table 2 for placing workpieces to be painted.

[0026] Usage method:

[0027] During use, water is stored in the water tank 4 so that the water level in the water tank 4 submerges the water level pipe 22 but does not submerge the slag removal box 21. The water pump 5 is turned on to pump the stored water in the water tank 4 into the water supply pipe 10. A part of the water supply pipe 10 is connected to the position of the spiral nozzle 8. Through the spiral nozzle 8, spray water is formed. The spray water falls on the baffle 7 to form layers of water curtains. The water flow returns to the water tank 4 through the water level pipe 22 at the bottom of the slag removal box 21; another part of the water supply pipe 10 extends deep into the overflow box 9. When the water in the overflow box 9 is full, it overflows and forms a water curtain on the water curtain plate 17. The water curtain flows down along the water curtain plate 17 and the serrated plate 18 and falls into the water tank 4.

[0028] The cold air blower 14 is turned on. The air flow in the workshop is sent to the static pressure chamber 13 through the cold air blower 14, where the dynamic pressure is converted into static pressure, and then enters the operation room 1 through the filter cotton 16, making the air in the operation room 1 flow evenly downward as a whole; under the action of the exhaust fan in the operation room 1, the gas fluidity is enhanced. The air flow passes through the water curtain formed by the serrated plate 18 between the water tank 4 and the water curtain plate 17, initially purifying and absorbing the paint and other harmful gases in the exhaust gas, and then entering the purification chamber 3. Through the turning of the three-layer baffle 7, a centrifugal force is formed. The layers of water curtains adsorb the paint in the exhaust gas, and the turning centrifugal force separates the water vapor in the air flow. After passing through the baffle 7, it simultaneously passes through the spray area formed by the spiral nozzle 8 to adsorb and remove the exhaust gas.

[0029] The gas remaining after being intercepted by the layers of water curtains enters the water vapor filtering device 11. Through the hollow balls in the water vapor filtering device 11, the water vapor in the air flow is effectively removed, and at the same time, the paint adsorbed in the water vapor is removed. The waste residue filtered out in the purification chamber 3 falls into the slag removal box 21 and is taken out after accumulating a certain amount.

[0030] During this process, the position of the baffle adjustment plate 19 can be changed to control the size of the ventilation opening area formed by the serrated plate 18 and the baffle adjustment plate 19, thereby controlling the gas flow rate to reach the optimum, improving the efficiency of the paint mist in the exhaust gas being adsorbed by water, accelerating the purification and ventilation of the exhaust gas in the working environment, and further improving the safety of the working environment. The specific position can be adjusted to the best effect on-site according to the actual situation.

[0031] In this embodiment, the filter material in the water vapor filtering device 11 is selected as hollow balls, and the laying thickness of the hollow balls exceeds 500 mm. Filter materials such as ceramics and fibers can also be used.

[0032] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. Any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
