Description

Technical Field

[0001] The utility model relates to the technical field of wet desulfurization systems, in particular to a wet desulfurization tower door device that is convenient for slag cleaning. Background Art

[0002] Wet desulfurization refers to the desulfurization process before the flue gas is discharged after combustion. It is one of the important technical measures to prevent and control air pollution. The desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. The flue gas enters the wet absorption tower of the desulfurization device and contacts with the alkaline limestone slurry droplets sprayed from top to bottom in countercurrent. The acidic oxide SO2 and other pollutants such as HCL and HF are absorbed, and the flue gas is fully purified; the slurry after absorbing SO2 reacts to generate CaSO3, which is generated by forced oxidation and crystallization in situ to generate CaSO4·2H2O. After dehydration, the commercial grade desulfurization byproduct - gypsum is obtained, and finally the comprehensive treatment of sulfur-containing flue gas is achieved; however, after the byproduct gypsum is formed in the desulfurization tower, it is easy to precipitate and scale in the desulfurization tower.

[0003] Scaling is one of the main reasons that affect the safe and stable operation of lime and gypsum wet flue gas desulfurization systems. To address this problem, stable process control, stable slurry parameter control, and reasonable control of important parameters such as slurry density and pH value can alleviate the scaling problem of the tower body. However, after a long period of operation, scaling always exists at the bottom of the desulfurization tower. It is difficult to deal with the scaling problem at the bottom of the desulfurization tower. Many manufacturers shut down the tower for manual cleaning, resulting in high labor intensity, difficult cleaning, and long downtime. An inspection door is set at the bottom of the desulfurization tower. Due to the large size and height of the desulfurization tower, the design of the inspection door is very important.
