[0001] The utility model relates to the technical field of air scrubbers, in particular to a secondary steam air scrubber. Background Art
[0002] The scrubber is a device used to purify waste gas, mainly used to remove pollutants and harmful substances in the waste gas. Its working principle is to pass the waste gas through the packing layer in the tower, and use the surface area of the packing and the effect of the liquid to make the pollutants in the waste gas contact with the liquid and adsorb on the surface of the liquid, so as to achieve the purpose of purifying the waste gas.
