Solid-liquid phase conversion brine concentration device

Abstract

The invention discloses a solid and liquid phase inversion saline water concentration device. The solid and liquid phase inversion saline water concentration device comprises a cold storage container conveying chain rows which are connected end to end, wherein the cold storage container conveying chain rows are meshed with a driving chain wheel and a plurality of driven chain wheels respectively; the driving chain wheel and the plurality of driven chain wheels are rotationally arranged on a frame respectively; the driving chain wheel is in transmission connection with a driving motor through a driving shaft; a plurality of cold storage containers are arranged on the cold storage container conveying chain rows; a cold storage agent of which the condensation point is below 0 DEG C is stored in the cold storage containers; the cold storage container conveying chain rows pass through a cold storage pool, an icing pool and a deicing pool in sequence, and return to the cold storage pool; the icing pool is provided with an inlet and an outlet of saline water needing to be concentrated; the cold storage pool is used for lowering the temperature inside the cold storage pool by using a refrigerating system. The solid and liquid phase inversion saline water concentration device has the advantages of simple production process, prevention of scaling, corrosion and the like in a saline water concentration process, long service life, low saline water concentration cost, high efficiency and very excellent energy-saving effect.

Description

technical field [0001] The invention relates to a solid-liquid phase conversion brine concentration device. Background technique [0002] A large amount of salty wastewater will be produced in the production field, and the direct discharge of such wastewater will cause pollution and damage to the environment. If salty wastewater seeps into the soil system, it will cause soil organisms and plants to die due to dehydration, causing the disintegration of the soil ecosystem. If it is discharged directly without treatment, it will bring great pressure to the water environment and accelerate the pollution of rivers and lakes. eutrophication process. With the development of industry and the shortage of water resources, the concentration of saline production wastewater produced by some industrial industries is getting higher and higher, and the discharge volume is increasing, which brings more and more environmental pressure. Therefore, the research on the treatment technology of ...
