Desulfurization wastewater treatment device adopting efficient clarifier

Abstract

The invention discloses a desulfurization wastewater treatment device adopting an efficient clarifier. The device comprises a wastewater cyclone, the efficient clarifier, an outlet water tank, a drug adding treatment box, a secondary clarifier and an outlet water pump. The wastewater cyclone is communicated with the efficient clarifier through a pipeline, the overflow port of the efficient clarifier is communicated with the outlet water tank through a pipeline, and a liquid level difference exists between the overflow port of the efficient clarifier and the outlet water tank. The outlet water tank is communicated with the drug adding treatment box through a pipeline, which is provided with the outlet water pump. The water outlet of the drug adding treatment box is communicated with the secondary clarifier. A liquid level difference exists between the water outlet of the drug adding treatment box and the secondary clarifier. And the outlet water tank is internally equipped with an outlet water tank liquid level measurement meter. According to the invention, the absorption tower slurry chloride ion concentration is ensured in a scope of design, and long-term, safe and stable operation of the desulfurization system is guaranteed.

Description

technical field [0001] The invention relates to the field of desulfurization wastewater treatment and environmental protection chemical industry, in particular to a desulfurization wastewater treatment device using a high-efficiency clarifier. Background technique [0002] Wet desulfurization process is the most widely used desulfurization process in my country. The absorption tower mainly adopts spray tower, and there are also types such as swirl plate tower and packed tower. The absorption process is mainly through spraying gypsum slurry with a certain pH value and flue gas. The gas is fully scrubbed and contacted to achieve the removal of SO in the flue gas 2 the goal of. on SO 2 During the absorption process, HCL, dust and other substances carried in the flue gas are absorbed together and dissolved into the gypsum slurry, which will cause the concentration of chloride ions in the gypsum slurry of the absorption tower to rise rapidly and the accumulation of fine particle...
