Abstract

The invention relates to a wet chemical oxidation waste gas treatment device which comprises a demisting bed, a catalytic packing bed, packing and a dosing pump. Demisting packing is contained in the demisting bed, the catalytic packing bed is arranged at the bottom of the demisting bed, the packing is contained in the catalytic packing bed, and a solid catalyst is adopted as the packing; one side of the demisting bed and one side of the catalytic packing bed are provided with observation windows respectively, the demisting bed and the catalytic packing bed are both arranged in an oxidation tower, one side of the oxidation tower is provided with a circulating water pump and the dosing pump, the oxidation tower and the circulating water pump are arranged in a water tank which is mechanically connected with a PH meter, and the circulating water pump enters the catalytic packing bed through a water pipe; the bottom of the oxidation tower and the dosing pump are each provided with a tap water supplying device, a medicine liquor backflow device is arranged outside the dosing pump, and the medicine liquor backflow device is provided with a liquid level protection switch; the top of the oxidation tower is provided with an exhaust chimney, one side of the exhaust chimney is provided with a sampling hole, the packing is in the shape of a honeycomb, the appearance of the packing is in a square or circular shape, and no less than eight nozzles are arranged on the water pipe.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a wet chemical oxidation waste gas treatment device, the technical fields of environmental protection technology and air pollution control. Background technique [0002] Volatile organic compounds (VOCs) are a class of pollutants that have attracted much attention in the atmospheric environment. Their sources are extremely extensive and can cause serious harm to human health and the atmospheric environment. Photochemical reactions of oxides lead to serious fine particle pollution, which is one of the "culprits" of frequent haze weather. Research on volatile organic compounds (VOCs) treatment technology has increasingly become one of the important directions in the field of environmental pollution control. [0003] At present, the VOCs treatment technologies that have been applied and are being developed in the world mainly include adsorption method, condensation method, absorption...

AI Technical Summary

Problems solved by technology

However, due to the low gas-liquid mass transfer efficiency, during the use of this method, there are problems such as insufficient contact between the oxidant in the liquid phase and the pollutants in the gas phase, which eventually leads to low pollutant degradation efficiency and insufficient utilization of the oxidant.
