[0002] The salt we often talk about in life mainly refers to sodium chloride, which is the most common condiment in life. Every person and every family cannot do without it. It is one of the most important substances for human survival. Salt is a very important commodity in history. It mainly comes from seawater evaporation and salt mining. Salt is also an important chemical raw material. It can be used to produce chlorine, hydrogen, hydrochloric acid, sodium hydroxide, chlorate, hypochlorite, bleaching powder and metallic sodium, etc. Highly refined sodium chloride can be used to make physiological saline solution for clinical treatment and physiological experiments, such as sodium loss, water loss, blood loss, etc. Salt is mainly produced by concentrating and crystallizing seawater or natural salt lake or salt well water.

[0003] Existing salt production equipment generates hot steam when the product evaporates. First, the hot air rises, causing the humidity in the equipment operating environment to be too high, resulting in low salt evaporation efficiency and shortened equipment service life; secondly, the evaporated hot steam is not recycled, resulting in loss and waste of hot steam; finally, hot steam overflows around the equipment and can easily cause burns, increasing production safety risks.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-temperature brine automatic cooling and recovery system is proposed. Utility Model Content
