A grid is laid at the mouth of the water pool 1, and an operator can spray paint on the grid. An air pipe 2 is laid between the liquid level of each water pool 1 and the grid, and the air pipes 2 are connected with an air exhaust duct positioned outside the paint spraying workshop.
According to the factory building paint spraying waste gas treatment system provided by the embodiment of the invention, the water pools 1 are respectively arranged below the paint spraying area, and the water pools 1 are connected with each other to form a water flow circulating system; and air pipes 2 are laid between the water pool 1 and the grating, and the air pipes 2 are connected with an external air exhaust duct to form an air exhaust system. Wherein, exhaust system and water circulation system all are located the below of the station of spraying paint, can directly discharge the waste gas that produces when the operation of spraying paint, can also directly discharge the residue that the production of spraying paint into water circulation system simultaneously and carry out the sediment operation.
Wherein, when the painting area is arranged in a row along the length direction of the painting workshop, the plurality of water pools 1 are connected end to end through the laid pipelines. As shown in fig. 1, two rows of paint spraying areas are arranged in the paint spraying workshop, each row is provided with three paint spraying areas distributed at equal intervals, and the six paint spraying areas are sequentially connected to form a water flow closed loop. Be equipped with dykes and dams between pond 1 and the pond 1, set up on the dykes and dams with flexible room slide rail 15 of flexible room adaptation, flexible room is installed and is gone back and forth to slide along the extending direction of slide rail on flexible room slide rail 15. The dam is provided with a water passing channel 13 so as to be communicated with two adjacent water pools 1, and two ends of the water passing channel 13 are arranged right opposite to the middle parts of the water pools 1.
Wherein, can lay a plurality of flexible rooms in the workshop of spraying paint, form a plurality of spray paint regions in the workshop of spraying paint with the help of a plurality of flexible rooms. In addition, a plurality of partition boards may be disposed in the painting shop, and a plurality of painting areas may be formed in the painting shop by the partition boards, which is not limited in the embodiment of the present invention.
The two adjacent water pools 1 are communicated through water passing channels 13, and the depth of each water passing channel 13 is larger than that of the two water pools 1 connected with the water passing channel. When water flows between the water pools 1, the water passing channel 13 which is slightly deep between the two water pools 1 is filled, and the water which overflows the water passing channel 13 enters the next water pool 1. In order to clean the paint slag deposited in the water channel 13, the front end of the water channel 13 is provided with a slag settling tank 4. It should be noted that the front end of the water passage 13 refers to the end of the water passage 13 that passes through first along the water flow direction, and the end of the water flow that flows out of the water passage 13 along the water flow direction is the rear end of the water passage 13. The depth of the water passage 13 can be deep to supply water to each pool, and the water passage 13 also has the function of a water well. The depths of the water pools 1 can be consistent, and a water pump is arranged in each water pool 1 for pumping water; of course, the depth of each basin 1 can be different, and a water pump can still be installed in each basin 1.
In order to reduce the number of water pumps and reduce the cost, the depths of the plurality of pools 1 are sequentially increased along the water flowing direction. As shown in fig. 2, the pool 1 with the deepest depth is a first pool 11, the pool 1 with the shallowest depth is a second pool 12, a water collecting well 3 is arranged in the water passing channel 13 between the first pool 11 and the second pool 12, and the depth of the water collecting well 3 is formed by a groove dug deeply in the water passing channel 13 and is deeper than the depth of other water passing channels 13. A water pump is arranged in the water collecting well 3. Under the action of the water pump, water in the water collecting well 3 enters the second water pool 12 and then flows to the next water pool gradually under the action of gravity, and the water pump is not needed to be involved, so that the closed-loop circulation of water flow can be realized only by arranging the water pump at the starting end of water flow circulation.
Specifically, in the embodiment of the invention, the depth difference between two adjacent pools 1 is 25cm, 30cm or 35 cm. In this regard, the embodiment of the present invention is not particularly limited as long as it can ensure that the water flows toward the next water pool 1 under the action of gravity. In order to ensure smooth flow of water, the bottom of the pool 1 may be inclined in a direction along the flow of water.
In addition, in order to prevent the water depth in the water pool from being too deep to affect the normal operation of the air pipe, an overflow dam 14 is further arranged on one side of the water pool 1, and the overflow dam 14 is arranged along the width direction of the water pool 1.
In the embodiment of the present invention, the duct 2 includes a main duct 21 and a plurality of branch ducts 22. The branch pipes 22 are arranged in parallel, the same side ends of the branch pipes are connected with the main pipe 21, and the main pipe 21 is laid on one side of a paint spraying area and connected with an air exhaust duct. Each branch pipe 22 is provided with a plurality of air suction openings 23. Therefore, the factory painting waste gas treatment system provided by the embodiment of the invention forms negative pressure in a painting area by virtue of the air exhaust duct, the exhaust inlets 23 absorb waste gas generated in the painting operation, and the plurality of branch pipes 22 are arranged, so that the exhaust inlets 23 arranged on the branch pipes are arranged at each position of the painting area, and the exhaust effect of the waste gas is improved. An air duct groove 5 is further formed in the dam between every two adjacent water ponds 1, an exhaust pipe is laid in the air duct groove 5, one end of the exhaust pipe is communicated with the main pipeline, and the other end of the exhaust pipe is communicated with an external exhaust air duct. As shown in fig. 2, the air duct groove 5 may be opened at an upper side of the water passing passage 13, thereby reducing damage to the floor in the painting shop.
Specifically, the branch pipes 22 include six branch pipes 22, and the extending directions of the six branch pipes 22 are all parallel to the extending direction in the jig frame 6. Wherein, bed-jig 6 includes two pole settings and sets up the horizontal pole in two pole settings, and the extending direction of bed-jig 6 refers to the length direction of horizontal pole in the bed-jig. Six branch pipes 22 are arranged at regular intervals in the tank 1 in the painting area in order to discharge the exhaust air all over the painting area. The number of branch pipes 22 can be three, four or other number, depending on the size of the pool and the need.
Wherein, the grid upper berth is equipped with the bed-jig 6 that is used for settling the piece of waiting to spray paint, and the extending direction of main pipeline 21 is perpendicular with the extending direction of bed-jig. When the region of spraying paint is separated by flexible room and is formed, the flexible direction in the flexible room of direction perpendicular to of laying of trunk line 21, bed-jig 6 extends along the flexible direction in flexible room, and trunk line 21 is laid and is extended at the flexible end in flexible room and along the width direction of door. When painting, the piece to be painted is placed on the jig frame, so that the operator can paint.
Wherein, install the exhaust fan on the wind channel of airing exhaust, can form the negative pressure in the area of spraying paint with the help of the exhaust fan, need not to lay other fan structures in the workshop of spraying paint.
