Description

Technical Field

[0001] The utility model relates to the technical field of demisters, in particular to a desulfurization tower demister capable of alleviating dirt blockage. Background Art

[0002] The desulfurization tower demister is a device used in the flue gas desulfurization system, mainly used to remove particulate matter and droplets in the flue gas during the desulfurization process. In the flue gas desulfurization process, the commonly used desulfurization method is wet desulfurization, among which the limestone-gypsum method is a common wet desulfurization process. In this process, when the flue gas passes through the desulfurization tower, it will come into contact with the limestone slurry injected into the desulfurization tower, so that the sulfur dioxide in the flue gas is absorbed and converted into gypsum.

[0003] The Chinese utility model patent with application number 202221333247.1 discloses a desulfurization tower demister that reduces dirt blockage. Although the utility model rotates the disc seat through the turntable handle so that the disc seat and the inner wall of the cylinder are perpendicular to each other, the disc seat cooperates with the sealing ring to block the output end of the cylinder, and then the water pump, valve pipe and high-pressure fan are turned on in sequence, and the air duct body can pass high-pressure airflow into the cylinder. The high-pressure airflow can impact the blocked parts inside the demister, which can quickly reduce the blockage degree of the demister. The nozzle sprays cleaning liquid toward the demister, and with the high-speed airflow, the foreign matter inside the demister can be quickly cleaned, achieving the purpose of simple cleaning method and good cleaning effect. However, the utility model rotates the disc seat through the turntable handle, and the disc seat cannot be fixed. When the flue gas passes through the cylinder, there is a situation where the disc seat rotates and blocks the cylinder, affecting the normal passage of the flue gas; and after the disc seat blocks the cylinder, when the high-speed airflow enters the cylinder, the disc seat will be flushed open, reducing the cleaning effect.
