The invention discloses a desulfurization wastewater chloride ion removal regeneration agent supersaturation crystallization device and method, the device comprises a configuration box, an agent storage tank and a discharge port, one side of the configuration box is provided with a transport pump, one end of the transport pump is provided with a transport pipeline, and a sealing gasket is embedded in one end of the transport pipeline; a clamping block is arranged on the surface of the sealing gasket, a clamping hoop is connected to the surface of the clamping block, and a bolt is connected to the interior of the clamping hoop. According to the desulfurization wastewater chloride ion removal regeneration agent supersaturation crystallization device and method, the regeneration agent is prepared in the preparation box and inputted into the agent storage tank through the conveying pump, the stirring device is started for stirring, and the stirred solution is inputted into the crystallization tank through the water pump; the remaining high-concentration chloride liquid serves as a solvent, fresh tap water is inputted through a water injection opening to prepare a regeneration agent again, and finally the prepared regeneration agent is injected into a storage tank so that the regeneration agent solution can be purified more efficiently.
Description
technical field [0001] The invention relates to the technical field of desulfurization wastewater treatment equipment, in particular to a supersaturated crystallization device and a method thereof for desulfurization wastewater to remove chloride ion regeneration agents. Background technique [0002] Impurities in desulfurization wastewater from thermal power plants come from flue gas and limestone for desulfurization, mainly including suspended solids, supersaturated sulfite, sulfate and heavy metals: many of them are the first category of pollutants that are required to be controlled in the national environmental protection standards. Particularity, the treatment of desulfurization wastewater is difficult; at the same time, due to the strong pollution of various heavy metal ions to the environment, desulfurization wastewater must be treated separately, and dechlorination treatment of desulfurization wastewater is a very important step , with the development of science and ...
