Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-2, an automatic dechlorinating device for desulfurization waste water of power plant comprises a housing and a long tube 4, wherein the housing is internally provided with a distillation chamber 1, a reaction chamber 2 and a settling chamber 3, the distillation chamber 1 is used for distilling waste water to primarily remove chloride, the housing is detachably connected with the long tube 4, the top of the distillation chamber 1 is provided with an evaporation hole, the side surface of the housing is fixedly provided with a storage tank 5 for storing chloride, the evaporation hole is communicated with the external storage tank 5 through a condensation tube 11, and the distillation chamber 1, the reaction chamber 2, the settling chamber 3 and the long tube 4 are all communicated. The distillation chamber 1 is arranged at the top of the shell, and the inner wall of the distillation chamber 1 is provided with a high-temperature heating rod 6 for evaporating chloride in the wastewater; the reaction chamber 2 is arranged below the distillation chamber 1, a replenisher 7 for replenishing a precipitation reagent is arranged in the reaction chamber 2, and the replenisher 7 is fixedly arranged on the side wall of the reaction chamber 2; the bottom of reaction chamber 2 still is equipped with stirring rake 8, and the inside still mosaic of reaction chamber 2 is equipped with motor 9, and this motor 9 passes through gear engagement with stirring rake 8.
