Rubber-mixing waste gas deodorizing and purifying device and method through dry oxidation

Abstract

The invention relates to a rubber-mixing waste gas deodorizing and purifying device and method through dry oxidation. The purifying device comprises a bag collector, an ozone generator, an oxidation reactor and a gas adsorptive oxidation device, wherein the bag collector is connected to the air outlet of the oxidation reactor through a draught fan; the ozone generator is connected to the air outlet of the oxidation reactor; the air outlet of the oxidation reactor is connected to the gas adsorptive oxidation device through a pipeline; and the gas adsorptive oxidation device is provided with a purified gas exhaust outlet. The purifying method comprises the following steps: introducing the rubber-mixing waste gas into the bag collector to carry out flue gas dust removal; generating ozone through the ozone generator; mixing the gas which is purified by the bag collector with the ozone to perform an oxidation reaction; and adsorptively oxidizing the gas which is subject to the oxidation reaction. The rubber-mixing waste gas deodorizing and purifying method has a simple device, stable operation, high purification efficiency and low cost, and does not have the problem of secondary pollution.

Description

technical field [0001] The invention relates to a purification device and method, in particular to a deodorization and purification device and method for rubber-making waste gas. Background technique [0002] In the production process of rubber tires, processes such as vulcanization and rubber mixing all produce process odorous exhaust gas. Pollution factors are industrial dust and odor pollutants. The pollution components of rubber processing waste gas are more complex and can be roughly divided into the following categories: sulfur compounds: methyl mercaptan, dimethyl disulfide, sulfide, hydrogen sulfide, etc.; dust: carbon black, sulfur; hydrocarbons: such as olefins, Aromatic hydrocarbons; oxygen-containing organic substances: such as phenols, aldehydes, ketones, organic acids, etc. Among them, carbon black and sulfur are inorganic substances, and most other odorous gas pollution components are organic substances. [0003] At present, the common deodorization methods...
