Folded plate type demister for treating flue gas desulfurization waste gas

Abstract

The invention discloses a folded plate type demister for treating flue gas desulfurization waste gas. The folded plate type demister comprises a protective shell, two demisting cavities are formed in the side wall of the protective shell, air inlet pipes are arranged at the inner tops of the demisting cavities, and first separation plates are rotationally connected to the inner bottoms of the demisting cavities; a second separation plate is rotatably connected to the upper end of the first separation plate, a supporting plate is fixedly connected to the upper end of the second separation plate, a sliding groove is formed in the bottom in the demisting cavity, and a driving device for driving the supporting plate to move up and down is installed in the sliding groove. By alternately blowing entrainment-containing airflow into the two demisting cavities, the two supporting plates can be sequentially driven to move up and down under the action of the driving device, so that the included angle between the first separation plate and the second separation plate is continuously changed, the entrainment gathered at the corner is guided into the interception tank, the washing difficulty can be greatly reduced, and meanwhile, the consumption of water resources for cleaning can be saved.

Description

technical field [0001] The invention relates to the related technical field of flue gas desulfurization equipment, in particular to a folding-plate mist eliminator for treating waste gas from flue gas desulfurization. Background technique [0002] In the waste gas treatment process of wet desulfurization, the pollutants in the flue gas are often sprayed into slurry through the spray tower, and the mist eliminator captures the mist particles and slurry droplets entrained in the flue gas. [0003] Among them, the folded plate demister is through the gas containing mist flowing into the demister, and the mist collides with the corrugated folded plate, its kinetic energy is reduced, the speed is reduced, and it is trapped on the surface of the folded plate. However, due to the bent structure of the folded plate, a large amount of trapped mist often gathers at the corner of the folded plate. When the demister is cleaned, the amount of water directly flushed by the high-pressure w...

Problems solved by technology

However, due to the bent structure of the folded plate, a large amount of trapped mist often gathers at the corner of the folded plate. When the demister is cleaned, the amount of water directly flushed by the high-pressure water flow to the corner is less, and the cleaning of a large amount of mist Limited effect and therefore tend to consume huge water resources
