Concentrated desalting device and desalting method for industrial high-salinity wastewater treatment

Abstract

The invention discloses a concentrated desalting device for industrial high-salinity wastewater treatment and a desalting method.The concentrated desalting device comprises a treatment tank, a motor, a heating element, a discharge port and a valve, a liquid inlet is fixed to the top of the treatment tank, a steam outlet pipe is fixed to one side of the treatment tank, and an output shaft of the motor is rotationally connected with a movable cylinder; and a stirring rod is fixed to the end of a connecting shaft, a sleeve block is arranged on the outer side of a fixed block in a sleeving mode, a transmission shaft is connected to the end of a movable cylinder, a heating element is installed in a first valve plate in an embedded mode, and a discharging opening is formed in the lower corner of the treatment tank. According to the concentrated desalting device and desalting method for treating the industrial high-salinity wastewater, the wastewater can be kept in a flowing state all the time in the desalting process of the industrial high-salinity wastewater, and other fixed substances contained in the wastewater can be treated, so that the desalting efficiency is improved; and and meanwhile, salt adhering to the interior of the pipeline can be cleaned, and the blocking phenomenon is avoided.

Description

technical field [0001] The invention relates to the technical field of industrial high-salt wastewater treatment, in particular to a concentrated desalination device and a desalination method for industrial high-salt wastewater treatment. Background technique [0002] High-salt wastewater refers to wastewater containing high salinity, and most of the high-salt wastewater comes from industrial wastewater, and the direct discharge of industrial high-salt wastewater will cause serious pollution to soil and water sources, so it is necessary to treat the salt in industrial high-salt wastewater It can be discharged after treatment. Usually, the desalination of industrial high-salt wastewater adopts a concentrated method, that is, by heating the wastewater, the water contained in the wastewater is evaporated, and then the remaining salt is crystallized and finally discharged. For example, the publication number is CN210457792U Concentration and desalination device for desalination ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a concentrated desalination device and desalination method for industrial high-salt wastewater treatment, to solve the above-mentioned background technology, it is proposed that the existing desalination device heats the wastewater during the desalination process, and the wastewater is mostly in a static state, so The evaporation rate of wastewater is too slow, and some salt will remain in the delivery pipeline of the device, and long-term adhesion will affect the smoothness of wastewater circulation
