These waste gases include carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, dust and production dust. Discharged into the atmosphere, they will pollute the air. These substances enter the human body through the respiratory tract in different ways. Some directly cause harm, and some have an accumulation effect, which will more seriously harm human health. In industrial production, industrial waste gas needs to be introduced into an exhaust gas absorption tower for purification and absorption.

The inlet pipe is fixedly installed on the left wall of the absorption tower, and the outlet pipe is fixedly installed on the top of the absorption tower. A water pumping device is fixedly installed outside the right wall of the absorption tower. A water suction pipe is arranged at the bottom of the water pumping device, and the left side of the water suction pipe is inserted into the absorption tower. A liquid infusion pipe is fixedly installed on the front side of the water pumping device, and the left side of the liquid infusion pipe is inserted into the side wall of the absorption tower. The left end of the liquid infusion pipe is fixedly installed with a spray head. A bottom plate is arranged below the inner side of the absorption tower, and several levers are arranged above the bottom plate. The levers are fixedly installed on a rotating shaft. Compared with the prior art, the beneficial effects of the utility model are as follows: by disturbing the air flow through a turbine device, the air flow can fully contact with the mist, increasing the dust removal effect; the turbine device can drive the water pump to operate and provide power for the water pump, thus saving energy and being more energy-efficient. After further retrieval, the "exhaust gas absorption tower for industrial environmental protection" disclosed in the patent application No. "201820347230.9", the main gas pipeline can transmit industrial waste gas to the absorption cylinder through the spray gas pipeline.
