[0003] However, the existing sulfuric acid waste gas still has certain defects in the purification treatment. Although the existing purification device can purify the sulfuric acid waste gas, because the waste gas discharged from the production of sulfuric acid contains a part of sulfuric acid gas, the sulfuric acid gas dissolves

Embodiment approach
[0034] As an embodiment of the present invention, the diameter of the circular pipe of the separation pipe 11 is gradually reduced, and the pipe wall on the lower side of the separation pipe 11 is provided with a tapered drain hole, and the opening end of the tapered liquid drain hole is located in the separation pipe. 11 inside. The tapered liquid discharge hole is conducive to the accumulation of liquid, which is conducive to the timely discharge of liquid and prevents the gas from taking the liquid away again.
[0035] Further, a separator is installed in the separation pipe 11, and a plurality of separators are arranged at intervals along the separation pipe 11, and the separator is used to separate gas and liquid; the separator includes a water throwing pan 21 and a water throwing motor 22, the The water throwing tray 21 is installed in the separation pipe 11 with the center of the circle. The water throwing motor 22 is used to drive the water throwing tray 21 to rotate. ...

The invention belongs to the technical field of sulfuric acid waste gas treatment, and in particular relates to a sulfuric acid waste gas desulfurization method. The method comprises the following steps: introducing sulfuric acid waste gas into a cyclone dust collector to remove solid particles in the sulfuric acid waste gas; introducing the sulfuric acid waste gas subjected to dust removal into an aerosol chamber, wherein the aerosol chamber contains a great deal of water vapor; dissolving the sulfuric acid gas in the water vapor so as to realize separation of sulfuric acid and the waste gas;introducing the sulfuric acid waste gas discharged from the aerosol chamber into a gas-liquid separator, and removing the liquid in the sulfuric acid waste gas by using the gas-liquid separator; discharging part of the water vapor along with the waste gas, and separating sulfuric acid liquid in the waste gas by using the gas-liquid separator so as to realize the recovery of the sulfuric acid; introducing the sulfuric acid-free waste gas discharged from the gas-liquid separator into a purification tower, purifying the waste gas by means of the purification tower and then directly discharging the purified waste gas into the atmosphere. The method adopts a classification and segmentation treatment way of solid, liquid and gas, realizes effective treatment of the sulfuric acid waste gas, andhas the characteristics of being good in desulfurization effect, little in environmental pollution and less in equipment investment, and the like.
Description
technical field [0001] The invention belongs to the technical field of sulfuric acid waste gas treatment, in particular to a sulfuric acid waste gas desulfurization method. Background technique [0002] Sulfuric acid has a wide range of uses. In the metallurgical industry, sulfuric acid is used in the production and processing of non-ferrous metals. In the petroleum industry, gasoline, lubricating oil and other petroleum products, refining of concentrated sulfuric acid is required to remove sulfur compounds and Unsaturated hydrocarbons and the waste gas produced in the production process of sulfuric acid have a great impact on the environment. The main component of acid rain contains sulfuric acid, so the waste gas produced in the production process of sulfuric acid needs to be purified before being discharged into the air. [0003] However, the existing sulfuric acid waste gas still has certain defects in the purification process. Although the existing purification device c...
