Problems solved by technology

The spray method consumes a lot of power and the spray hole is easy to block. Although the use of carbon nanotubes can increase the evaporation rate of seawater by about 30%, it is very difficult to treat, separate and recycle the carbon nanotubes. If the carbon nanotubes are not treated , carbon nanotubes are easily blown away by wind

Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0028] see figure 1 The device for bubbling and sunning salt in seawater shoals provided by the embodiment of the present invention is arranged for use in existing salt pans, and includes bubbling tube arrays, air pipes 32, blowing equipment 31, and an automatic environmental monitoring and control system (Fig. Not shown in), at least one layer of anti-seepage black film 1, fillers, etc., the above components will be described one by one below.

[0029] The anti-seepage black film 1 is laid on the bottom of the salt pan to prevent seawater from seeping into the salt pan and improve the utilization rate of light. It can be laid in multiple layers, such as two or three layers. In this embodiment, the anti-seepage black film 1 is a black high-density polyethylene anti-seepage film...

Abstract

The invention provides a bubbling baysalt device applied to a seawater shoal. The device comprises a bubbling unit arranged in a salt pan, so that bubbles are continuously generated on the surface of seawater in the salt pan. By adopting the device provided by the invention, the baysalt period can be shortened, the yield of the salt pan is improved, the adaptive capacity of the salt pan to severe climates is enhanced, and the speed of conventional seawater baysalt is improved by 2-4 times. In addition, the device can be distributed in an existing salt pan and the original salt pan is slightly modified. The device is easily automatically operated and controlled, and has strong feasibility.

Description

technical field [0001] The present invention relates to the field of salt drying by seawater evaporation, in particular to a device for bubbling salt drying in seawater shoals. The method applies the traditional bubbling operation process to concentrated seawater drying salt, and a large number of micro-bubbles are blown out and the bubbles are broken. Many tiny liquid droplets ejected during the process increase the contact area between the air and seawater, thereby accelerating the rate of seawater evaporation and drying of salt. Background technique [0002] my country has a long coastline, and sea salt drying in coastal areas is a traditional industry. Salt is not only an important living substance necessary for people's lives, but also an important raw material for the chlor-alkali industry, which is used to produce bulk chemical raw materials such as caustic soda, soda ash, and chlorine. Minerals such as potassium, bromine, and magnesium can also be extracted from bitt...
