Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly industrial waste gas purification, in particular to an environmentally friendly industrial waste gas purification device. Background Art

[0002] Energy conservation, emission reduction and the development of green economy are receiving more and more attention. However, in the current industrial production and daily chemical processing, wastewater, waste gas and waste residue are inevitably generated. In particular, the waste gas in the industrial production process contains a large amount of fatty alcohols, aldehydes and ketones, which makes the tail gas have obvious odor, and through air convection, the odor will soon spread over a large area, affecting the surrounding environment. When treating the waste gas, the waste gas is usually mixed with the purification liquid for reaction, and then the waste gas is desulfurized, denitrated and deodorized. However, when treating the waste gas, the waste gas usually passes through the treatment device in a straight line. Due to the linear behavior of the waste gas, the waste gas stays in the treatment chamber for a short time during treatment, which affects the treatment effect of the waste gas. Especially when the waste gas in the pipeline is discharged in a concentrated manner, the gas in the second half is difficult to fully contact with the purification liquid, which affects the treatment effect of the waste gas. For this reason, we propose an environmentally friendly industrial waste gas purification device. Utility Model Content
