Problems solved by technology

[0005] At present, although the sun-dried salt has adopted the method of condensing the evaporation pool, the intermediate adjustment pool, and the crystallization pool step by step to improve the production efficiency, this method of salt production still requires the natural evaporation of the water surface of the ponds at all levels to gradually concentrate the brine.
[0006] The water surface of the salt pond is low, the effective evaporation area is small, the solar energy utilization rate is low, the water evaporation is slow, the salt production cycle is long, the production efficiency and production benefit are low, which seriously restricts the development of solar salt enterprises

Abstract

The invention relates to a method for accelerating sun-dried salt making by a hydrophilic material and a device. The device comprises a buoyancy layer, a water supply layer and a light absorption layer, wherein the buoyancy layer is cylindrical, the water supply layer wraps the periphery of the buoyancy layer, the light absorption layer wraps the periphery of the water supply layer, and thus, a device body can be cylindrical; and both the water supply layer and the light absorption layer have hydrophilicity. According to the method and the device, the device achieves rapid sun-dried salt making through accelerating moisture evaporation by using a hydrophilic optothermal material. The device is cylindrical, and one face, located above a water surface, of the device is arc-shaped, so that the surface of the device can be thoroughly irradiated by sunlight from various angles, and the light absorption area is increased. Heat is generated and is conducted to the surface of the water supplylayer after the light absorption layer absorbs light energy, so that a layer of water film between the light absorption layer and the water supply layer is heated, and the flash evaporation of moisture is achieved.

Description

technical field [0001] The invention relates to the technical field of solarization of salt, in particular to a method and a device for accelerating the drying of salt by hydrophilic materials. Background technique [0002] There are many types of salt, such as sea salt, pool salt, well salt, rock salt, etc. Sea salt has the longest history of development in my country. As early as 5,000 years ago in the Xia Yu period, there was a record of "cooking the sea into salt"; more than 4,000 years ago, my country began to produce pool salt; Salt wells have been dug in the Chengdu Plain to extract brine and fry salt; [0003] The development of rock salt in modern times has made great progress, and rock salt deposits with large reserves have been proved in Hebei, Shanxi, Jiangsu and other places. The methods of making salt include boiling salt, solar evaporation (solar salt), freezing method, vacuum evaporation and hot pressing evaporation. However, the above methods not only have...
