Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of desulfurization, more particularly, it relates to an automatic adjusting type mist capturing device for a desulfurization pipeline. BACKGROUND

[0002] Currently, in the power industry, in order to reduce the emission of sulfur dioxide, the wet desulfurization process is generally used. This process treats harmful substances in coke oven gas through a desulfurization tower, but a large amount of dust and water mist is generated in this process. Although the existing mist capturing device can capture water mist to some extent, in long-term operation, a large amount of dust will accumulate on the surface of the mist capturing plate, which significantly affects the mist capturing effect and the operation efficiency of the system. These accumulated dust reduces the precision of mist capturing and even blocks the mist capturing plate, which negatively affects the stability of the system.

[0003] Common cleaning methods include spray cleaning and airflow blowing. Although these methods can theoretically remove dust from the surface of the mist capturing plate, due to the multi-layer arrangement of the mist capturing plate, dust on the upper mist capturing plate often falls onto the lower mist capturing plate, resulting in limited cleaning effect. Therefore, although the dust accumulation problem can be alleviated to some extent, dust cannot be completely removed, which affects the overall performance of the mist capturing device.

[0004] In view of the problems existing in the prior art, the present application provides a device that can effectively solve the problem of serious dust accumulation on the surface of the mist capturing plate. This not only improves the overall performance of the desulfurization equipment, but also reduces the maintenance frequency and cost of the system, further promoting the development of environmental protection technology.
