Abstract

The invention discloses a heat exchange separator capable of preparing ice crystals and salt crystals simultaneously by utilizing seawater. The heat exchange separator comprises a closed refrigerant evaporation part, an ice scraping motor, an ice scraping knife, a shell and a salt crystal collecting container, wherein the top of the shell is connected with the refrigerant evaporation part; the lower part of the shell is conical; the lower part of the shell is connected with the salt crystal collecting container through a salt crystal outlet receiving pipe and a salt crystal collecting control valve; the ice scraping knife is arranged on an output shaft of the ice scraping motor; the ice scraping knife is mounted on the top of the shell and is contacted with an ice crystal crystallization part of the refrigerant evaporation part; an ice crystal outlet receiving pipe is arranged on the top of the shell; an ice crystal collecting control valve is mounted on the ice crystal outlet receiving pipe; and a seawater inlet receiving pipe and a fresh seawater outlet receiving pipe are arranged on the shell. According to the heat exchange separator, the temperature of the seawater is reduced by utilizing heat absorption caused by evaporation of the refrigerant; and fresh water is crystallized and separated out of the seawater and the salt crystals are separated out by utilizing the extraction technology principle. The heat exchange separator separately collects the ice crystals and the salt crystals, integrates preparation of the ice crystals and the salt crystals, and increases the effectively utilization ratio of the seawater.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat exchange separator for simultaneously producing ice crystals and salt crystals by using seawater. Background technique [0002] With the increasing shortage of fresh water resources, seawater utilization has gradually become a research hotspot. [0003] At present, the use of seawater is mainly to use seawater to produce dynamic ice slurry. Using the physical and chemical characteristics of seawater and the principle of crystallization technology, fresh water crystallizes from seawater to form particle ice, which is suspended in the solution to form dynamic ice slurry. Dynamic ice slurry is mainly used for temperature control such as preservation and refrigeration. [0004] Because the dynamic ice slurry is a mixture of ice crystals, salt crystals and fresh water, its application range is limited. Therefore, it is an urgent problem to realize the effective separati...
