A harmful gas treatment device used for environment protection engineering

Abstract

The invention relates to the technical field of harmful gas treatment devices, and discloses a harmful gas treatment device used for environment protection engineering. The device includes a gas treatment device main body inside which an absorption bin is disposed. Stirrers are disposed in the absorption bin. One end of the main body is provided with a liquid discharging pipe, and the lower end ofthe main body is provided with roller wheels. The inside of the main body, close to the upper part of the absorption bin, is provided with a drying bin in which a dehumidifier is disposed. The external surface of the front end of the main body, close to the upper part of the drying bin, is provided with a control panel. The device enables harmful gas absorption with a liquid firstly with a high gas absorption efficiency. The device is environmentally friendly, low in cost, convenient to operate during gas drying, and capable of rapid replacement of activated carbon, and substances of energy sources in treated gas can be recovered and utilized.

Description

technical field [0001] The invention relates to the technical field of harmful gas treatment, in particular to a harmful gas treatment device for environmental protection engineering. Background technique [0002] Common toxic and harmful gases can be divided into: Irritant gases——gases that irritate the eyes and mucous membranes of the respiratory tract. It is a poisonous gas that is often encountered in the chemical industry. There are many types of irritating gases, the most common ones are chlorine, ammonia, nitrogen oxides, phosgene, hydrogen fluoride, sulfur dioxide, sulfur trioxide, and dimethyl sulfate. Toxic gas asphyxiating gas can be divided into simple asphyxiating gas, blood asphyxiating gas and cell asphyxiating gas. Such as nitrogen, methane, ethane, ethylene, carbon monoxide, nitrobenzene vapor, hydrogen cyanide, hydrogen sulfide, etc., irritating gases exist in many industrial production processes, such as electric welding, electroplating, smelting, chemica...

AI Technical Summary

Problems solved by technology

[0003] Traditional tail gas treatment devices generally use chemical reaction methods for treatment. This method will waste a lot of resources, and the treatment effect is not good. After using activated carbon to absorb harmful gases, the activated carbon is not easy to replace, and the activated carbon cannot be reused. Some gas It contains a lot of water vapor and dust. If these substances are not disposed of at the beginning, it will affect the subsequent treatment of harmful gases. In addition, many gases are also very important resources after conversion. These gases will pollute the environment and damage human health when they are discharged into the air. , such as carbon monoxide can be used as water gas after reaction, but the traditional treatment method is direct absorption or burning, which is not only not environmentally friendly but also causes a lot of waste of resources and increases investment costs. In order to solve the above problems, we propose this Harmful gas treatment device for environmental protection engineering
