Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dry desulfurization equipment, specifically a dry desulfurization equipment with high desulfurization efficiency. Background Technology
[0002] Dry desulfurization is a flue gas desulfurization technology that does not require water or solution treatment. It primarily purifies the flue gas by reacting solid adsorbents or catalysts with sulfur dioxide (SO2) in the flue gas to form solid sulfides or sulfates. Dry desulfurization is suitable for small and medium-sized boilers, industrial furnaces, or areas with scarce water resources, offering advantages such as simple equipment, no wastewater discharge, and easy treatment of byproducts. However, existing dry desulfurization equipment uses activated carbon to adsorb sulfur dioxide from the flue gas. During adsorption, once the surface layer is saturated, the adsorption efficiency of the activated carbon below decreases, and cleaning the activated carbon after it has reached a certain adsorption level is inconvenient. Therefore, improvements to the existing technology are needed. Utility Model Content

[0023] The specific implementation process of this utility model is as follows: In use, flue gas is introduced into the desulfurization tower 1. Inside the desulfurization tower 1, the activated carbon inside the carbon barrel 2 adsorbs sulfur dioxide in the flue gas. At the same time, the motor 12 is started, and the motor 12 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the stirring rack 11 to rotate, which can disturb the activated carbon inside the carbon barrel 2. At the same time, the rotating shaft 10 drives the gear 13 to rotate. The gear 13 drives the gear 15 to rotate through the gear 2 14. The gear 15 drives the carbon barrel 2 to rotate in the opposite direction to the stirring rack 11 through the internal gear ring 16, which can increase the disturbance speed of the activated carbon, thereby effectively improving the adsorption efficiency of the activated carbon.
[0024] When activated carbon needs to be cleaned, a mixture of water vapor and oxygen is injected into the inside of the diversion pipe 8 through the steam pipe 7. The gas is sprayed into the activated carbon inside the carbon barrel 2 through the nozzle 9. During the disturbance, the sulfur dioxide on the surface of the activated carbon can catalyze the production of sulfuric acid with water vapor and oxygen. The sulfuric acid accumulates at the bottom of the desulfurization tower 1. After the treatment is completed, the pull ring rod 52 is pulled, which drives the sealing plug 55 to move. At the same time, the spring 54 is compressed by the fixing plate 51. When the sealing plug 55 is disengaged from the drain pipe 4, the sulfuric acid produced during the cleaning can be discharged.
