Volatilization kiln desulfurization equipment for waste steel slag treatment and using method thereof

Abstract

The invention discloses volatilization kiln desulfurization equipment for waste steel slag treatment and a using method of the volatilization kiln desulfurization equipment, the volatilization kiln desulfurization equipment comprises a tank body, an ash deposition plate is arranged in the tank body, and a scraping plate is arranged on the ash deposition plate to automatically clean the ash deposition plate; a pull ring and an impact block are arranged on the side wall of the tank body to vibrate off dust particles attached to the inner wall to the ash deposition plate, so that the dust particles are prevented from being accumulated due to inconvenience in cleaning to influence the working efficiency of desulfurization equipment; a spiral water pipe and a fin plate are arranged to recover heat of sulfur-containing flue gas fed into the tank body, meanwhile, a partition plate is arranged to separate an inner cavity of the tank body, so that the sulfur-containing gas is separated from thedust particles, sulfur-containing substances in the sulfur-containing gas are oxidized and dissolved through hydrogen peroxide, and byproducts such as dilute sulfuric acid are generated; the whole equipment is compact in structure and reliable in performance, resources are saved while the environment is protected, the labor intensity of workers is relieved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a desulfurization equipment, in particular to a volatilization kiln desulfurization equipment used for waste steel slag treatment and a use method thereof. Background technique [0002] Sulfur dioxide is an acidic gas that causes acid rain and an indirect greenhouse gas that causes the greenhouse effect, causing extensive harm to the environment and significant economic losses. Flue gas desulfurization is recognized as the mainstream and fundamentally effective technical control means. [0003] A large amount of sulfur-containing flue gas will be produced during the treatment of waste steel slag. If these sulfur-containing flue gases are directly discharged into the atmosphere, it will cause serious environmental pollution; However, it is inconvenient to clean the inside of the desulfurization equipment, and a large amount of heat in the sulfur-containing flue gas is wasted. Due to the pollution of dust in the flue gas, the ex...

AI Technical Summary

Problems solved by technology

[0006] (1) How to automatically clean the ash plate by setting the ash plate inside the tank, and setting a scraper on the ash plate, and setting a pull ring and an impact block on the side wall of the tank to attach it to the inner wall The dust particles are shaken to the ash accumulation board, which solves the problem of inconvenient cleaning inside the desulfurization equipment in the prior art;

[0007] (2) How to recover heat from the sulfur-containing flue gas sent into the tank by setting spiral water pipes and fin plates, so as to solve the problem of heat loss and waste of sulfur-containing flue gas in the desulfurization equipment in the prior art;
