Treatment device for industrial waste gas

Abstract

The invention discloses a treatment device for industrial waste gas. The treatment device comprises an annular hollow shell and a cooling box arranged on one side of the shell, an elastic cavity used for storing low-boiling-point evaporation liquid is formed in the shell, an annular cooling cavity is formed in the shell, and the cooling cavity is filled with cooling liquid; and a one-way valve used for limiting flowing of the cooling liquid is fixedly connected to a second communicating pipe. Cooling fins can rotate anticlockwise under the action of gravity, thus, the cooling fins attached to the lower inner wall of the shell in the past are not attached to the inner wall of the shell, heat dissipation is conducted in the cooling liquid, and the process is repeated; and the heat island effect caused by too high external environment temperature due to the fact that high-temperature waste gas is directly exhausted into the surrounding environment is avoided, cloud and fog in the sky of a city cannot be increased, harmful gas and smoke dust are prevented from being accumulated in the sky of the city, and therefore serious atmospheric pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a treatment device for industrial waste gas. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during fuel combustion and production processes in the enterprise factory area. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist) lead mercury, beryllium compounds, smoke and productive dust, which will pollute the air when discharged into the atmosphere. These substances enter the human body through the respiratory tract in different ways, some directly cause harm, and some have a cumulative effect, which will seriously endanger human health. [0003] At present, a large amount of high-temperature exhaust gas produced by some factories is directly discharged...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. Because a large amount of exhaust gas and waste heat are discharged into the air, the temperature of the air near the ground is higher than that of the surrounding suburbs, causing the "heat island effect" to occur. The exhaust gas cannot be diffused and can only be concentrated in the city. The urban air pollution cannot be alleviated, making the urban air quality worse. At the same time, under the influence of the "heat island effect", the clouds and fog over the city will increase, making harmful gases , Smoke and dust accumulate in the urban area, forming serious air pollution, and a treatment device for industrial waste gas is proposed
