Demister for desulfurization tower

Abstract

Provided is a demister for a desulfurization tower. The demister is characterized by comprising a supporting ring, a supporting shaft located in the middle of the supporting ring, and a plurality of blades which are distributed around the supporting shaft and fixed between the supporting ring and the supporting shaft. Each blade comprises two blade units connected together and a hook blade body bent towards the lower portion of the outer side, the sections of the blade units are in an upwards-protruding arc shape, and each hook blade body is connected below one of the two blade units of each blade. The blades are inclined upwards from the blade units connected with the hook blade bodies to the other blade units. Compared with the prior art, the demister has the advantages that large-particle solids and small-particle solids can be removed at the same time, meanwhile, resistance losses can be reduced, the number of flushing devices can be reduced, the demisting effect of the desulfurization tower can be improved, and the investment cost and running cost of the desulfurization tower are reduced.

Description

Technical field: [0001] The invention relates to an environment-friendly sulfur removal technology. Background technique: [0002] At present, the demisting section of the desulfurization tower usually adopts the method of connecting multiple demisters in series to remove secondary fine dust and mist droplets. For example, first set up a layer of corrugated plates to remove large particles, and then set up a layer of swirl plates to remove small particles. This method of cascading multiple demisters has the following disadvantages: [0003] 1. The multi-stage demister requires more installation space, which increases the height of the tower and the manufacturing cost; [0004] 2. Multi-stage demisters require more flushing devices for flushing and descaling. For example, the first-level demister requires two-layer flushing devices, and the second-level demister requires three-layer flushing devices, which increases the investment cost; [0005] 3. The increase in the numb...

Problems solved by technology

[0003] 1. The multi-stage demister requires more installation space, which increases the height of the tower and the manufacturing cost;

[0004] 2. Multi-stage demisters require more flushing devices for flushing and descaling. For example, the first-level demister requires two-layer flushing devices, and the second-level demister requires three-layer flushing devices, which increases the investment cost;

[0005] 3. The increase in the number of demisters has resulted in an increase in resistance, resulting in a higher load on the induced draft fan at the front section of the desulfurization tower
