Problems solved by technology

[0002] At present, the desulfurization of domestic power plants is mainly based on the purchase of foreign technology use rights. Some enterprises have mastered wet limestone-gypsum flue gas desulfurization through independent development or introduction, digestion and absorption. The form of vertical counter-current spray tower, the height difference between the inlet and outlet of the absorption tower is more than 20 meters, the connecting flue between the equipment is lengthy and complicated, the system layout is loose, the resistance of the flue gas is large, it is necessary to add a desulfurization booster fan, and the flue is large in size, heavy in load, The supporting structure is complicated, which makes the existing technology costly, consumes a lot of power, consumes a lot of steel, and occupies a large area

Abstract

The invention relates to sulfur dioxide pollution control technology which adopts a U-shaped absorption region high speed advection spray tower characterized by a flue gas inlet and a flue gas outlet at a same side and with a same height; a U-shaped absorption region advection absorption tower mainly comprises a flue gas inlet, a flue gas outlet, an absorption tower body, and an inlet-outlet connecting flue; the invention solves the problem of redundant flue systems in the prior art, greatly reduces the flue gas resistance, equipment height, and land occupation, and improves the desulphurization effect of the equipment.

Description

Technical field: [0001] The invention relates to a sulfur dioxide pollution control technology, which belongs to the field of environmental protection of power plants. Background technique: [0002] At present, the desulfurization of domestic power plants is mainly based on the purchase of foreign technology use rights. Some enterprises have mastered wet limestone-gypsum flue gas desulfurization through independent development or introduction, digestion and absorption. The form of vertical counter-current spray tower, the height difference between the inlet and outlet of the absorption tower is more than 20 meters, the connecting flue between the equipment is lengthy and complicated, the system layout is loose, the resistance of the flue gas is large, it is necessary to add a desulfurization booster fan, and the flue is large in size, heavy in load, The supporting structure is complicated, so that the existing technology has high cost, high power consumption, high steel cons...
