Problems solved by technology

For example, in the traditional low-temperature flue evaporation, due to the fast flow rate of the flue gas, a large number of waste water droplets are brought into the desulfurization tower by the flue gas before the evaporation is complete, resulting in low efficiency of the evaporation system, and the incomplete evaporation of waste water droplets It is also very easy to cause corrosion and dust accumulation in the downstream flue

Abstract

The invention relates to the technical field of desulfurization wastewater treatment, in particular to a high-salinity wastewater low-temperature concentration treatment device which comprises an adjusting tank 1, a clarification tank 2, a buffer tank 3 and a flue 4, wherein the regulating tank 1, the clarification tank 2, the buffer tank 3 and the flue 4 are sequentially communicated. The flue 4comprises a flue body, a plurality of water distributors 5 and a plurality of drainage parts; the buffer pool 3 is communicated with the water distributor 5; a plurality of water inlets 7 are formed in the top wall of the flue body; wherein all the water distributors 5 are movably arranged on the outer side of the flue body, all the drainage components are arranged in the flue body, and the drainage components penetrate through the water inlet 7 and are connected with the water distributors 5 through a water inlet pipe 8. The device effectively solves the problems that the efficiency of an evaporation system is low and the interior of a flue 4 is corroded and scaled due to the fact that the flow speed of flue gas is high and wastewater droplets are brought into a desulfurizing tower 15 when not evaporated completely.

Description

technical field [0001] The invention relates to the technical field of desulfurization wastewater treatment, in particular to a low-temperature concentration treatment device for high-salt wastewater. Background technique [0002] With the rapid development of my country's economy, a large amount of wastewater is produced every day, among which the treatment of high-salt wastewater has received more and more attention. [0003] Among them, the desulfurization wastewater discharged from the wet desulfurization system of coal-fired power plants has complex components and many types of pollutants, and is one of the most difficult wastewater to treat in coal-fired power plants. At present, the chemical precipitation method is mainly used in China to treat desulfurization wastewater. The wastewater is directly discharged after neutralization, sedimentation and flocculation to remove heavy metal impurities. However, due to the presence of a large amount of sulfate and chloride in ...
