Provided with tank, the tank horizontally extending bottom to front chamber is provided with dividing plate between front chamber and rear chamber, under dividing plate
Leave gap between horizontal plane in portion and tank, the air in front chamber enters rear chamber through the gap；
Step 3, water pump is opened, the sewage in tank is circulated with water treatment system.
Blower fan in the step 2 drives the air-flow in air main to be flowed towards one end away from blower fan, and rear chamber passes through one
Connection tracheae is connected with the center section of air main, and connection tracheae is obliquely installed with air main, and connects tracheae away from air main
One end be located at nearly blower fan side.
The spray nozzle in rear chamber is opened, the air in rear chamber circulates from the bottom up, vaporific steam caused by spray nozzle
Spray from top to bottom.
Water screen generator is provided with front chamber, inwall of the current along front chamber flows from top to bottom caused by water screen generator
It is dynamic, and converge into tank.
Open the second blower fan, high pressure draught caused by the second blower fan from the import position of front chamber towards front chamber in
Injection, for driving waste gas to enter front chamber.
It is provided with above tank and stirs rod, the bottom for stirring rod contacts with the water surface in tank, when stirring rod rotation, stirs
Rod flows with the greasy dirt on the water surface in dynamic water tank from front chamber position towards rear chamber position.
After above structure, the gas recovery method of spraying coating line of the invention is compared with prior art with following excellent
Point：First, it is not easy to be infected with coating on the blade of blower fan, therefore service life is grown, maintenance cost is low, secondly, waste gas maximum journey
Degree is deposited on the water surface, therefore recovering effect is good.

Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
The present invention provides a kind of gas recovery method of spraying coating line, and it includes
Step 1, by the nozzle on spraying coating line towards the position of import 1.1 of front chamber 1, produce nozzle spraying workpiece
Waste gas enter front chamber 1；
The blower fan 3 that step 2, unlatching connect with rear chamber 2, for detaching the air in rear chamber 2, the rear chamber 2
Bottom is provided with tank 4, the horizontally extending bottom to front chamber 1 of tank 4, dividing plate is provided between front chamber 1 and rear chamber 2
5, gap 6 is left between the horizontal plane in the bottom and tank 4 of dividing plate 5, after the air in front chamber 1 enters through the gap 6
Chamber 2；
Step 3, water pump is opened, the sewage in tank 4 is circulated with water treatment system.
Above-mentioned waste gas refers to the coating particles of the discarded mist formed in spraying process after nozzle spraying workpiece.
Blower fan 3 in the step 2 drives the air-flow in air main 7 to be flowed towards one end away from blower fan 3, and rear chamber 2 is logical
Cross a connection tracheae 8 to connect with the center section of air main 7, connection tracheae 8 is obliquely installed with air main 7, and it is remote to connect tracheae 8
One end from air main 7 is located at the nearly side of blower fan 3.When producing swiftly flowing air-flow in air main 7, due to connecting gas
Pipe 8 is obliquely installed with air main 7, therefore the air connected in tracheae 8 can be carried over the air-flow in air main 7, be reached
