Method for preparing salt by atomizing seawater with natural energy source and collecting distilled water

Abstract

The invention relates to a method for preparing a salt by atomizing seawater with a natural energy source and collecting distilled water. The method is characterized in that a salt preparing facility is arranged in a solar wind power station; pneumatic impellers are arranged on the lower part of the wind drum of the power station; the pneumatic impellers are connected with a centrifugal spray slinger; the upper part of the wind drum is provided with an arc-shaped wind brim; multiple arc condensation sheets and a loudspeaker-shaped draft tube are arranged under the wind brim; the pneumatic impellers drive the slinger to rapidly rotate, brine is atomized so as to rapidly remove water, and a part containing salt falls in a brine pool; the evaporated water together with hot air enters the wind drum to synthesize fast-ascending air current; on the one hand, the air current passes through the pneumatic impellers and multiple wind driven generators and then flows out of the wind drum; and onthe other hand, because external air current flows through the wind brim, flow velocity is accelerated, pressure is reduced, the air current flowing out of the wind drum is pumped to ascend and then flows out from gaps among the condensation sheets, and one part of steam is condensed by contacting the condensation sheets to be condensed so as to form distilled water. By using the method, the salt-preparing efficiency is improved, and distilled water is collected.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering, in particular to a method for producing salt and distilled water by using natural energy. Background technique [0002] Salt production methods include boiling salt, solar evaporation, freezing, vacuum evaporation, and hot-press evaporation. In addition to solar evaporation of salt, the rest of the methods almost all consume a lot of energy. Since sun-dried salt uses solar and wind energy to evaporate water and concentrate brine, it is the most economical and environmentally friendly traditional method of salt production. However, although the current sun-dried salt adopts a more advanced step-by-step concentration method to improve production efficiency, it still relies on the principle of gradually concentrating the brine by natural evaporation of the water surfaces of the brine pools at all levels. The disadvantage is that the evaporation of water is slow, and it is almost...

Problems solved by technology

[0003] The purpose of the present invention is to propose such a salt production method in view of the current situation that salt drying mainly utilizes the natural evaporation of the water surface of brine pools, the efficiency is low, and the evaporated water cannot be collected: first, without changing the brine pools of all levels In the case of large area and no energy consumption, expand the area of ​​water evaporation, increase the temperature and air velocity of water evaporation, and improve the efficiency of water evaporation
