Efficient desulfurizing tower

Abstract

The invention discloses an efficient desulfurizing tower which comprises a desulfurizing tower body (1), wherein a gas inlet pipe (2) is connected to the desulfurizing tower body (1); the desulfurizing tower body (1) is connected with a first spraying pipe (3); a plurality of first nozzles (4) are connected to the first spraying pipe (3); a first demister (5) is connected above the gas inlet pipe(2) in the desulfurizing tower body (1); a second spraying pipe (6) is connected to the position, located above the first demister (5), of the desulfurization tower body (1); a plurality of second nozzles (7) with downward openings are connected to the second spraying pipe (6), a plurality of drainage plates (8) are connected to the position, located above the second spraying pipe (6), in the desulfurization tower body (1), and an exhaust port (12) is formed in the top of the desulfurization tower (1). Compared with the prior art, the desulfurization device has the advantages of simple structure, reasonable design, good desulfurization effect and greener and more environment-friendly effects.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to a high-efficiency desulfurization tower. Background technique [0002] The desulfurization tower is a tower-type equipment for desulfurization treatment of industrial waste gas. The desulfurization tower was originally built with granite masonry and was the most widely used. It uses the principle of water film desulfurization and dust removal. Desulfurization dust collector. The advantage is that it is easy to maintain, and the effects of dust removal and desulfurization (denitrification) can be achieved at the same time by preparing different dust removers. With the development of FRP technology, desulfurization towers are gradually made of FRP. Compared with granite desulfurization towers, FRP desulfurization towers are low in cost, easy to process, stainless and non-rotten, and light in weight. Therefore, they will become the development trend of desulfurization tower...

AI Technical Summary

Problems solved by technology

[0003] However, the structure of the existing desulfurization tower is complicated, the cross-sectional area of ​​the tower is equal everywhere, and the flow velocity of the flue gas is also equal everywhere in the tower. Although the flue gas and the spray liquid flow in reverse, the contact between the flue gas and the spray liquid is stable. , the amount of evaporated water is reduced, and the amount of water carried by solids in the flue dust is also reduced. The flue gas cannot be fully mixed with the spray water. The traditional desulfurization tower has a low absorption rate of sulfur dioxide and dust in the flue gas. The desulfurization effect is not good, and it is easy to have residues. Discharge into the air will not only endanger human health, but also pollute the environment, which is not conducive to environmental protection
