Desulfurization and denitrification treatment device for waste gas purification

Abstract

The invention discloses a desulfurization and denitrification treatment device for waste gas purification, and belongs to the field of waste gas purification. According to the scheme, flue gas can be mixed with an aqueous solution when entering a water tank, the flue gas enters an air bag through a through hole after being mixed, through the indirect oxidation action of thiobacillus deoxidans, thiobacillus deoxidans oxidizes sulfur dioxide in flue gas into sulfuric acid, and the thiobacillus deoxidans expands, so that purification of the aqueous solution on the flue gas is accelerated, and when the flue gas is discharged into the aqueous solution in the water tank, the aqueous solution fluctuates to drive the air bags to shake, so that the air bags collide with one another, and the aqueous solution in the water tank is stirred; the purification of flue gas further is accelerated, when the aqueous solution fluctuates, a baffle plate can float up and down, meanwhile, the water solution on the two sides of the smoke suction pipe and the smoke outlet pipe is pressed down, the fluctuation area of the water solution is concentrated between the smoke suction pipe and the smoke outlet pipe, and the shaking amplitude of the air bag is larger.

Description

technical field [0001] The invention relates to the field of exhaust gas purification, and more specifically relates to a desulfurization and denitrification treatment device for exhaust gas purification. Background technique [0002] Exhaust gas purification mainly refers to the treatment of industrial waste gas such as dust particles, flue gas, odorous gas, and toxic and harmful gases generated in industrial places. Common exhaust gas purification includes factory smoke and dust exhaust gas purification, workshop dust exhaust gas purification, organic waste gas purification, Waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc., the process of removing nitrogen oxides from combustion flue gas, and the importance of preventing environmental pollution have been sharply raised as a worldwide problem, and the mainstream in the world The process is divided into: SCR and SNCR. These two processes are not much different except that t...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, industrial sites will generate waste gas during production, and the waste gas needs to be desulfurized and denitrified. Desulfurization and denitrification are divided into wet desulfurization and denitrification and dry desulfurization and denitrification. Generally, wet desulfurization and denitrification are used for treatment. In the process of flue gas desulfurization and denitrification, it is generally necessary to spray and filter the flue gas to dissolve it in water, but when dissolving in water, the reaction efficiency is slow, which reduces the purification efficiency
