Method and device for accelerating salt-making brine evaporating by using vertical plate water absorption photo-thermal material array

Abstract

The invention discloses a method and a device for accelerating salt-making brine evaporating by using a vertical plate water absorption photo-thermal material array. The invention belongs to the technical field of salt production, seawater can be absorbed by utilizing the water absorption photo-thermal material on the basis of capillary action; under the action of light absorption heating balls embedded in the surface, efficient light absorption and utilization of solar energy are realized, conversed heat energy is transferred through a built-in heat conduction framework net to evaporate seawater; only the lower part of the water absorption photo-thermal material is inserted into a water body, the contact area with water surface is small, the loss of photo-thermal energy to the water bodyis greatly reduced, energy utilization rate is enhanced, meanwhile, the water absorption photo-thermal material is vertically placed on the water surface;, the evaporation area of seawater can be directly doubled, it is beneficial for utilization of wind energy, the evaporation area in contact with wind is enlarged, and the evaporation rate is increased; the flapping effect of water waves can be fully utilized to keep the surface of the water absorption photo-thermal material to be wet, the problem of salt precipitation on material surfaces is effectively solved, rapid evaporation of seawateris realized, the salt-making brine evaporating period is greatly shortened, and the salt-making brine evaporating amount is increased.

Description

technical field [0001] The invention relates to the technical field of salt production, and more specifically relates to a method and a device for accelerating the drying of salt by a vertical board water-absorbing photothermal material array. 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 draw brine and decoct salt; great progress has been made in the development of modern rock salt, and large reserves of rock salt deposits have been proven 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. [...

AI Technical Summary

Problems solved by technology

[0004] At present, although the sun-dried salt has adopted the method of step-by-step concentration in the evaporation pond, the intermediate adjustment pond, and the crystallization pond to improve the production efficiency, this method of salt production is still a The natural evaporation of the water surface at all levels should make the brine gradually concentrate

Due to the low pool water surface, small effective evaporation area, low solar energy utilization rate, slow water evaporation, long salt production cycle, low production efficiency and production benefits, it seriously restricts the development of sun-dried salt enterprises
