Problems solved by technology

[0011] These earlier PSSG systems have certain shortcomings. The most important thing is that these methods require a large amount of precious metals as raw materials, so the cost is very expensive, and it is difficult to prepare on a large scale.

Embodiment 1

[0043] The preparation method of this embodiment is as figure 2 As shown in the diagram, there are two steps in the illustration, namely the fabrication of carbon black transfer plate and the coupling of carbon black and substrate material PVA. The physical picture of the dry sample before and after coupling is as follows Figure 5 , magnified 2500 times the microstructure such as image 3 , Figure 4 . This embodiment 1 will describe the method of using this invention to prepare high-efficiency solar-driven water evaporation.

[0044] Present embodiment is as substrate material with PVA, and candle provides carbon black particle as high-carbon organic matter combustion, and glass sheet comprises five steps as refractory material: (1) cleaning of substrate material PVA; (2) carbon black transfer plate Production; (3) transfer of carbon black powder; (4) drying; (5) water evaporation test.

[0045] The detailed process of each step is as follows:

Embodiment 2

[0062] The preparation method of this embodiment is as figure 2 As shown in the diagram, there are two steps in the illustration, namely the fabrication of carbon black transfer plate and the coupling of carbon black and substrate material PVA. This embodiment 1 will describe the method of using this invention to prepare high-efficiency solar-driven water evaporation.

[0063] Present embodiment is as substrate material with PVA, and benzene provides carbon black particle as high-carbon organic matter combustion, and glass sheet comprises four steps as refractory material: (1) cleaning of substrate material PVA; (2) carbon black transfer plate Production; (3) transfer of carbon black particles; (4) drying; (5) water evaporation experiment.

[0064] (1) Cleaning of substrate material PVA

[0065] Same as Example 1, since organic impurities usually remain in industrially produced PVA materials, cleaning is required, and the cleaning steps are the same as Example 1.

Embodiment 3

[0074] Present embodiment uses sponge as substrate material, and ethylene provides carbon black particle as high-carbon organic matter combustion, and ceramic sheet is as refractory material, comprises four steps: (1) cleaning of substrate material sponge; (2) carbon black transfer plate Production; (3) transfer of carbon black particles; (4) drying.

[0075] (1) Cleaning of substrate material sponge

[0076] Sponge is divided into synthetic sponge and natural sponge. If it is synthetic sponge, it is the same as Example 1, because there are usually residual organic impurities in the synthetic sponge material produced in industry; There will be debris such as fine dust remaining; so it needs to be cleaned, and the cleaning steps are the same as in Example 1.

[0077] (2) Fabrication of carbon black transfer plate

[0078] The source of carbon black in this embodiment is the carbon black particles produced when ethylene is incompletely burned. Since ethylene is a gas under no...

Abstract

A light-heat-steam conversion material and a preparation method thereof, and the preparation method comprises the following steps: selecting a water-absorbing material, to be more specific, selectinga porous, highly water-absorbent and light-weight substrate material, cleaning the substrate material for standby use; preparing carbon black of a carbon black light-heat conversion coating, to be more specific, burning a high carbon organic matter, horizontally placing a refractory material above the high carbon organic matter to collect carbon black particles generated by the burning, and cooling the refractory material after collection of the carbon black particles; transferring the carbon black particles, to be more specific, wiping the surface with a carbon black coating of the refractorymaterial to transfer the carbon black particles to the surface of the water absorbing material until the surface of the water absorbing material is completely covered by the carbon black particles. Asimple desalination system of seawater or other wastewater prepared by the light-heat-steam conversion material is simple in operation, the material is cheap and easy to take, no electric energy is consumed, and the simple desalination system has good stability, and is suitable for large-area low-cost preparation.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and in particular relates to a light-heat-steam conversion material for seawater desalination and a preparation method thereof. Background technique [0002] In recent years, with the growth of the social population, the per capita fresh water resources have dropped significantly. How to obtain a large amount of fresh water has gradually become a hot issue that needs to be solved urgently. However, in current industrial applications, it is not practical to generate heat by burning coal to heat a steam engine equipped with seawater to generate water vapor, because the air pollution and energy consumption caused by coal combustion are not the same as the current energy-saving and environmental protection. The industrial development model deviates from it. [0003] The method of solar-driven water evaporation undoubtedly provides a promising key point for solving this problem. More t...
