Description

1. Technical field [0001] The invention belongs to the technical field of ecological engineering, and specifically relates to a method for making full use of wind energy and solar energy to greatly improve the efficiency of drying salt. 2. Background technology [0002] Salt can be mainly divided into sea salt, lake salt and well salt. China has used seawater to produce salt more than 5,000 years ago, lake salt has been produced more than 4,000 years ago, and wells have been drilled to extract underground natural brine to produce salt more than 2,000 years ago. The methods of making salt include boiling salt, solar evaporation (solar salt), freezing method, vacuum evaporation and hot pressing evaporation. Boiling salt is not only inefficient but also consumes a lot of energy; although electrodialysis, vacuum evaporation and hot-press evaporation salt production have improved efficiency, they still consume a lot of energy; freezing method is only suitable for salt production ...

AI Technical Summary

Problems solved by technology

At present, although the sun-dried salt has adopted the method of concentrating step by step in the evaporation pond, the intermediate adjustment pond, and the crystallization pond to improve the production efficiency, this salt production method still relies on the principle of gradually concentrating the brine by the natural evaporation of the water surface of each level of pond water. The water surface of the pool is low, the effective evaporation surface area is small, the solar energy utilization efficiency of the wind energy river is low, the water evaporates slowly, and the salt production cycle is long, which makes the production efficiency and production benefit low, which seriously restricts the development of solar salt enterprises.
