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 o

Embodiment Construction

[0012] (1) Production of moisture evaporation curtain system: Cut white cotton gauze with a width of 80cm into blanks with a length of 3m each, fold the length of each blank in half, merge, fold and sew the two free ends to form a double-layer In the shape of a curtain, the suture end is used as the top of the curtain, and a convenient hook is fixed at both ends of the top of the curtain, and a convenient hook is fixed at every 26cm between the two ends; the two layers of cloth of the curtain are sewed horizontally at a distance of 20cm from the top Together, form a horizontal channel surrounded by double-layer cloth between the top and the suture, that is, the solution distribution tube channel, and at the other end of the curtain, wrap a plastic rope with a length of 80 cm in the interlayer at the bottom of the curtain and connect it with the other end of the curtain. The bottom ends of the curtains are fixed together to form a moisture evaporation curtain; then 41 evaporatio...

Abstract

The invention relates to a method for fully utilizing wind and solar energy and substantially improving the efficiency of solar salt, pertaining to the technical field of ecological engineering. The invention comprises a water evaporation system, a suspension device of the evaporation system, a solution regular transmission system and a solution regular distribution system. By adopting the invention, full and sustainable use of the wind energy and the solar energy can be realized so as to speed up water evaporation, reduce energy consumption, shorten the cycle of solar salt and greatly improve salt production and the original production and design capacity on the basis of not increasing the area of a saltern.

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 ...
