Technology for efficiently separating solute from solvent

Abstract

The invention belongs to the field of chemical solute extraction, and discloses a technology for extracting a solute from a solution and application. The solute extraction method comprises the following steps: placing one fourth of the height of a heating core below the liquid level of a solution, placing three fourths of the heating core above the liquid level of the solution, and generating bubbles in the solution at the bottom of the heating core through a microporous aerator, and after the heating core is electrified and heated for a period of time, the solute is continuously separated out from the heating core above the liquid level and continuously climbs upwards, so that the purpose of extracting the solute is achieved. The extraction technology does not need to completely evaporate the solution, so that the energy loss is low, the extraction process is simple and convenient, and the extraction speed is higher than the traditional speed; the method has a good prospect when being applied to the field of chemical solute extraction.

Description

Technical Field

[0001] The invention belongs to the field of chemical engineering and relates to the discovery and application of a technology for extracting solutes from a solution. Background Art

[0002] In the chemical industry, the extraction of solutes from solutions usually involves directly heating the solution to evaporate, concentrate and crystallize it, which is often extremely energy-intensive, or using time-consuming methods such as sunlight and natural wind drying. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method and application for extracting a substance from a solution in a simple manner.

[0004] The purpose of the present invention can be achieved by the following technical bills:

[0005] The heating core makes the small amount of solution adsorbed on the surface of the heating core not completely evaporate while precipitating solutes, turning into a high-temperature, high-concentration solution; the high-temperature, high-concentration solution attracts the low-concentration solution at room temperature below to overcome its own gravity and climb upward, turning into a high-temperature, high-concentration solution and continuing to precipitate solutes on the surface of the heating core. Using an exhaust fan at the top of the heating core to remove the steam generated in this process will improve the efficiency of solute precipitation.

[0006] In this preferred technical implementation, the invention includes the following components: 12V heating core, 12V air pump, microporous aerator, exhaust fan, 12V power supply, high temperature resistant hose. (The reason for choosing the heating core instead of the semiconductor cooling sheet is that the heating core is not easily damaged by high temperature during operation, has higher heating power and lower market price than the semiconductor cooling sheet.)

[0007] The present invention provides a solute extraction technology, which comprises:

[0008] (1) Part of the heating element is below the liquid surface, and part of it is above the liquid surface.

[0009] (2) The solution is heated by a heating element to evaporate or partially evaporate.

[0010] (3) The steam generated during the heating process is extracted to improve the solute precipitation efficiency.

[0011] (4) The solution at the bottom of the heating core has a microporous aerator to produce bubbles. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below in conjunction with the examples. These examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. The process, conditions, experimental methods, etc. for implementing the present invention, except for the contents specifically mentioned below, are all common knowledge and common common sense in the art, and the present invention is not particularly limited.

[0017] Specifically, the elements are assembled.

[0018] Take 6 heating cores and arrange them vertically downward in a regular hexagon. Put a high-temperature resistant hose with suitable aperture and thickness vertically in the middle of the regular hexagon and fix it with high-temperature resistant tape. Connect the 6 heating cores in parallel to a 12V power supply, and connect the bottom of the hose to a microporous aerator; the other end of the hose is connected to a 12V air pump, and the air pump is connected to a 12V power supply.

[0019] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents. Without departing from the spirit and scope of the inventive concept, the changes and advantages that can be thought of by those skilled in the art should be included in the scope of the technical solution for which protection is requested by the present invention.

Claims

1. This technology is characterized by: Before heating begins, since there is adhesion between the surface of the heating core and the solution liquid, and the adhesion is greater than the mutual attraction between the liquid molecules, a small amount of solution will overcome its own gravity and the mutual attraction between the liquid molecules at the vertical intersection of the heating core surface and the solution surface, and adhere to the heating core surface above the solution surface; for example: the liquid in the measuring cylinder usually forms a concave liquid surface.

2. The bubbles generated by the microporous aerator will continue to push the small amount of solution described in claim 1 along the surface of the heating core.

3. When the power is turned on for heating, the heating core will first heat and evaporate the small amount of solution that is above the solution surface and attached to the heating core surface. Then, the solute will precipitate out and stick to the surface of the heating core at this position. As the temperature of the solution at this point increases, the solute concentration will also increase. The concentration of this part of the solution will be higher than the solution below the liquid surface, so that this small amount of high-temperature and high-concentration solution will not evaporate completely, and can attract the room-temperature and low-concentration solution below to overcome gravity and climb upwards, becoming a high-temperature and high-concentration solution. This is similar to the transpiration of plants.

4. At this time, an exhaust fan can be used to extract the steam generated in the process as described in claim 3, which is more conducive to the extraction efficiency of the solute.

5. As the heating element heats the surface of the solution, the temperature will increase the solubility of the solvent for the solute, and the solute at the bottom of the solution will move to the surface of the solution.

6. The solute solid that has been precipitated on the surface of the heating core has a porous structure, which can absorb more solution and facilitate evaporation and concentration to further precipitate the solute.

7. Since the liquid level of the solution will drop as the solvent in the solution evaporates during the process as described in claim 2, if the solute separator is fixed on the ground, the separator will eventually not be able to contact the liquid surface of the solution. This problem can be solved if the separator floats on the surface of the solution by a buoy.
