Device for desulfurization and recovery of seawater by industrial flue gas

Abstract

The invention discloses a desulfurizing seawater restoring device of industrial flue gas seawater, which comprises the following parts: pool (1), distribution region (2) interconnected by several separated transverse baffles, blending region (16), aeration region (3) and discharge region (5), wherein the fresh seawater inlet (6) is set in the distribution region (2); the desulfurizing seawater input pipe (7) is set in the blending region (16); the seawater drainage (8) is set in the discharge region (5); the aeration pipe (9) is set on the aeration region (3), which connects aeration fan (10) and several branch-pipes (11) with each end of branch-pipe (11) lying at aeration head (12) with vent hole (13) on the bottom of pool.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an industrial flue gas seawater desulfurization water quality recovery device. Background technique [0002] Exhaust gas from boilers and kilns commonly used in electric power, chemical industry, metallurgy and other industries contains a large amount of sulfur dioxide, which causes serious pollution to the atmosphere and is the main source of pollution for the formation of acid rain. Due to the needs of environmental protection, some or most of the SO must be removed from the flue gas emitted by industrial combustion devices before being discharged into the atmosphere. 2 , usually called flue gas desulfurization process, that is, FGD (flue gas desulphuration) process. At present, the lime / limestone-gypsum method commonly used at home and abroad uses the characteristics that lime or limestone can react with sulfur dioxide to perform wet desulfurization and scrubbing of flue gas to ac...

AI Technical Summary

Problems solved by technology

At present, the lime / limestone-gypsum method commonly used at home and abroad uses the characteristics that lime or limestone can react with sulfur dioxide to perform wet desulfurization and scrubbing of flue gas to achieve the purpose of purifying flue gas; but this method has its shortcomings For example, the final desulfurization by-product of the lime / limestone-gypsum method is gypsum. These gypsums are restricted by technology and market, and often cannot be commercialized. They can only occupy land for dumping and stacking, resulting in secondary pollution. These shortcomings are largely Restricted the development of desulfurization and environmental protection industry
