Abstract

The invention discloses a solid-liquid phase transition brine concentration method which comprises the following steps: preparing a plurality of cold storage containers, wherein cold storage agents with the solidifying point of 0 DEG C or lower are stored in the cold storage containers; placing the plurality of cold storage containers in a cold storage pool, wherein the temperature inside the cold storage pool is reduced by a refrigerating system; placing the plurality of cold storage containers in a freezing pool, and introducing brine to be concentrated into the freezing pool; taking out the cold storage containers of which the surfaces are frozen from the freezing pool after the surfaces of the cold storage containers in the freezing pool are frozen, and putting the taken cold storage containers with frozen surfaces into a deicing pool; and taking the cold storage containers out of the deicing pool after ice on the surfaces of the cold storage containers placed in the deicing pool is melted or drops, and putting the cold storage containers into the cold storage pool. The invention aims to provide a solid-liquid phase transition brine concentration method; and according to the method, the production process is simple, scales, corrosion and other problems difficultly occur in the brine concentration process, the service life of equipment is long, the brine concentration cost is low, the efficiency is high, and the energy-saving effect is very outstanding.

Description

technical field

[0001] The invention relates to a solid-liquid phase conversion brine concentration method. 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 ...

Embodiment Construction

[0024] The solid-liquid phase conversion brine concentration method of the present invention comprises the steps of:

[0025] A. Prepare a plurality of cold storage containers, and store a cold storage agent with a freezing point below 0°C in the cold storage containers;

[0026] B. Place a plurality of cold storage containers in the cold storage pool, the cold storage pool lowers the temperature inside the cold storage pool through the refrigeration system, and the temperature of the cold storage agent in the cold storage container from the frozen cold storage container is lower than 0 °C;

[0027] C, placing a plurality of cold storage containers obtained by step B in the freezing pool, introducing the brine that needs to be concentrated into the freezing pool, and allowing the cold storage containers to be immersed in the brine that needs to be concentrated;

[0028] D. When the surface of the cold storage container in the freezing pool is frozen, take out the cold storage ...
