[0044] When the waste gas needs to be washed twice, the air pump starts working, and the air pump extracts the purified waste gas in the tower body through the second air pipe, and the waste gas enters the spiral cylinder through the first air pipe, so that the waste gas and the liquid are mixed twice in the spiral cylinder. The first rack ring drives the first gear to rotate, the first gear drives the first shaft to rotate, the first shaft drives the second gear to rotate, and drives the spiral roller to rotate. The rotation of the spiral roller improves the efficiency of the secondary mixing of liquid and waste gas, and enhances the washing effect of the waste gas.
