In this embodiment, polluted industrial gases are generated during daily processing in chemical plants. These gases cannot be discharged directly, otherwise they will pollute the air, and a fume scrubber 1 is required.

First, fill the water tank 12 with alkaline washing liquid. After filling, operate the control panel 9 to start the flue gas washing machine 1. The first blower 4 rotates to exhaust air, and the industrial gas to be washed is drawn from the smoke inlet pipe 2 into the box body 7, and enters the washing area 71 through the guide baffle 16. The guide baffle 16 can effectively place the washing liquid into the smoke inlet pipe 2. At the same time, the second blower 5 works to draw the industrial gas out of the smoke outlet pipe 3. In this process, the industrial gas will pass through the washing area 71, and the washing area 71 will wash the industrial gas and filter out pollutants.

First, the industrial gas will pass through the filter layer 17, which will effectively filter out large particles of toxic impurities, and will be washed by the washing device 6 after passing through.

The washing device 6 draws washing liquid from the high-pressure water pump 13 and transports it to the connecting block 61 through the water pipe 132. The connecting block 61 diverts the washing liquid and transports it into the spray pipe 62. Then the washing liquid is atomized and sprayed out from the atomizing head 63 and sprayed out from the spraying head 64 at the same time. The spraying head 64 can effectively remove impurities remaining on the wall edge. Under the influence of gravity, the washing liquid will carry away the impurities in the industrial gas when it drips downward. At the same time, the alkali in the washing liquid can effectively remove the remaining chemicals in the industrial gas.

While the washing liquid is sprayed, the driving motor 11 drives the driving shaft 18 to rotate, and the driving shaft 18 drives the bevel gear 19 to make gear matching movements, thereby driving the rotating shaft 20 to rotate, and the rotating shaft 20 drives the rotating block 65 to rotate, and the rotating block 65 drives the spray pipe 62 to rotate, thereby achieving dead-angle washing of the industrial gas below.

After washing, the liquid will flow into the water storage area 72. The filter 15 can effectively filter out heavy metals and impurities in the liquid, effectively preventing the suction pipe 131 from being blocked, while ensuring that the recycled washing liquid is still very clean. The liquid in the water storage area 72 is pumped out from the suction pipe 131 and then enters the high-pressure water pump 13 for recycling.

While washing, the rotating motor 10 is turned on, and the rotating motor 10 drives the fan device 14 to work. The fan device 14 can effectively cool down the hot industrial gas.

During washing, the internal washing situation can be observed through the visual window 8, and the quality of the washing liquid can be observed at the same time, and the washing liquid can be replaced in time if it is not clean.

In the utility model, when washing industrial gas, alkaline washing liquid can be used. The rotatable washing device 6 ensures that the industrial gas can be washed without dead angles. The washing range is more comprehensive, and impurities attached to the inner wall of the box body 7 can be effectively washed away, effectively improving the gas quality of the industrial gas after washing. At the same time, the water storage area 72 ensures that the washing liquid can be recycled, reducing the use of washing liquid and effectively saving the processing cost required for washing.

The fan device 14 works while washing, which can effectively cool down the hot industrial gas. The internal washing situation can be observed through the visual window 8, and the quality of the washing liquid can be observed at the same time. If the washing liquid is not clean, it can be replaced in time.
