The rotation of the first bevel gear 7, under the action of the two second bevel gears 63, can drive the two rotating shafts 62 to rotate. The rotation of the two rotating shafts 62, through the cooperation of the cam 61, the overlapping top plate 65, the vertical rods 66 and the springs 67, can drive the guide plate 69 to sway up and down, so that the guide plate 69 can prevent the spray liquid from remaining on it while ensuring the gas is guided and divided. The cooperation between the fixed plate 68 and the vertical rods 66 can limit the movement direction of the guide plate 69. The L-shaped plate 64 can support the rotating shafts 62.
[0024] The operation steps of this utility model are as follows:
[0025] When using this device to spray gas, firstly, an appropriate amount of spray liquid is added to the inside of the spray tank 5 through the water injection pipe 13, so that the height of the liquid surface is higher than the height of the lower end of the air inlet pipe 14. After the spray liquid is added, the motor 12 and pump 3 are started. Then, the gas to be sprayed is transported to the inside of the spray tank 5 through the air inlet pipe 14. At this time, under the action of the spray liquid, the absorption and purification process of harmful substances and particulate impurities in the gas can be initially achieved. During this process, the rotation of the output shaft of the motor 12, under the action of the rotating rod 8 and the stirring blades 16, can drive the spray liquid inside the spray tank 5 to shake, thereby increasing the contact between the gas and the spray liquid when it enters the spray tank 5. The contact area is increased to improve the gas treatment effect of the device. Then, the gas after preliminary treatment moves upward inside the spray tank 5. Then, with the cooperation of the pump body 3, connecting pipe 2 and connecting pipe 4, the spray liquid inside the spray tank 5 can be drawn into the interior of the annular spray block 9 and sprayed out through several nozzles 10. At this time, the gas can be treated again. In the second process, the gas inside the spray tank 5 can be guided and divided by the flow guide plate 69, thereby increasing the contact area between the gas and the spray liquid, further increasing the spray reaction effect of the device on the gas. Finally, the gas after treatment is discharged from the interior of the spray tank 5 through the gas outlet pipe 11.
