Abstract

The invention relates to a salt-manufacturing method from bittern in a solar greenhouse. The method comprises the steps of preparing brine, filling a pool, crystallizing and harvesting the salt. The method is characterized in that brine is employed as raw material; the solar greenhouse is used as a salt-manufacturing device; processes of brine evaporation, crystallization and salt harvest are finished in the solar greenhouse; and natural salt such as high-quality industrial salt, insolation refined salt, insolation curing salt, low sodium salt and the like can be produced throughout the year. The produced salt has high quality; items of the insolation natural salt are various; and the method is fast in evaporation and crystallization speed; is not influenced by natural environment, and has high yield. Simultaneously, the old brine can be used comprehensively; and fresh water can be received. The method saves land and energy, and is environment-friendly.

Description

technical field [0001] The invention relates to a method for producing salt from brine, in particular to a method for producing salt from brine in a solar greenhouse. Background technique [0002] Our country has a long history of using seawater to make salt. As early as 4000 BC when Emperor Yan, there was a Susha family who boiled seawater into salt, that is, decocted salt with stew. In the struggle to understand nature and choose nature, after a long history, sea salt production has finally made a breakthrough, which is to change frying to drying. At the end of Ming Dynasty and the beginning of Qing Dynasty, people began to use mud ponds to dry salt, which is called natural salt. The evaporation pool is composed of neatly arranged salt fields. After being exposed to wind and sun, the brine is gradually concentrated to saturation, and then crystallized into salt. This is the first innovation in sea salt production. [0003] In the 1970s and 1980s, plastic thatch pond crys...
