Abstract

The invention discloses a device for removing dioxin through catalytic oxidation for waste gas treatment and a using method of the device, and belongs to the technical field of waste gas treatment. The device for removing dioxin through catalytic oxidation for waste gas treatment comprises a mixing container, an inlet flue and an outlet flue which are used for conveying flue gas are arranged at the two sides of the outer wall of the mixing container respectively, the outer wall of the mixing container is further connected with an ozone conveying pipe, adjusting valves are fixedly arranged on the outer wall of the inlet flue and the outer wall of the ozone conveying pipe, a gas mixing mechanism is arranged in the mixing container, the bottom of the mixing container is connected with a shell, the shell is communicated with the mixing container, a secondary mixing mechanism matched with the gas mixing mechanism is arranged in the shell, and a catalyst layer is arranged in the outlet flue. The flue gas and the ozone are mixed for multiple times, so that dioxin in the flue gas is efficiently oxidized by the ozone, the oxidation effect of the ozone is improved, the situation that the ozone is discharged before reacting with the dioxin is avoided, and the comprehensive operation cost of waste gas treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a device for removing dioxins by catalytic oxidation for waste gas treatment and a use method thereof. Background technique [0002] Dioxins usually refer to a group of polychlorinated substituted planar aromatic hydrocarbons with similar structures and physical and chemical properties, which belong to chlorinated oxygen-containing tricyclic aromatic hydrocarbons, and are extremely carcinogenic (rat liver cancer-causing dose 10pg / g) Multiple toxic effects including environmental endocrine disrupting effects at very low doses. Such substances are neither artificially produced nor used for any purpose, but are by-products of combustion and various industrial processes. At present, the main sources of dioxins in the environment are the evaporation caused by the use of chlorophenols for wood preservation and prevention of schistosomes, the discharge of incineration indus...
