Description
Technical Field
The invention belongs to the technical field of new energy preparation, and particularly relates to a solar thermal coupling hydrogen production device based on photocatalyst self-frequency division.
Background
In recent years, with the development and cooperation of hydrogen-oxygen fuel cell vehicles actively promoted in countries such as japan and korea in the international united states, the development direction of hydrogen energy for vehicles in China is more and more clear, and various industrial policies and plans are also developed by the countries and local governments, and the hydrogen energy is first brought into effect. However, at present, the research and development of core equipment of domestic hydrogenation stations are still in a starting stage, and a high-pressure hydrogen compressor system is imported. The domestic hydrogen compressor production enterprises are more, but the output pressure is below 30 MPa, and the technical requirements of the hydrogenation station cannot be met. Therefore, the development and the promotion of the hydrogen production technology are still necessary, and the solar photo-thermal coupling hydrogen production method based on the self-frequency division of the photocatalyst is one of the hydrogen production paths which are provided by people and can be efficient, low in cost, clean and pollution-free, and the pressure of the domestic hydrogen station construction can be effectively relieved.
The traditional photocatalytic water decomposition method is to irradiate a semiconductor material by sunlightWhen the material is loaded, photons with energy higher than the forbidden band width of the semiconductor are absorbed by the semiconductor, electrons on the valence band of the semiconductor are excited to jump to a conduction band, and holes are formed at the valence band position, which are called photo-generated electrons (e-) and photo-generated holes (h +), respectively. The photo-generated electrons and photo-generated holes can be used for reducing water and oxidizing water to generate H respectively2And O2. However, we notice that the photocatalytic water splitting method only uses most of ultraviolet light and part of visible light of solar energy as an excitation light source, but largely neglects the use of part of energy of solar energy and infrared light, and the conversion efficiency of solar hydrogen production is always in a low level. Based on this, it is desired to enhance the utilization of the infrared part of solar energy, i.e. the idea of producing hydrogen by photothermal coupling, in the reaction device. Since research on photo-thermal coupling hydrogen production is not extensive in universities and research institutes in China and international, and basic reaction devices are not particularly complete, the reactor design is necessary.

The invention aims to provide a solar thermal coupling hydrogen production device based on photocatalyst self-frequency division, which is used for evaluating the hydrogen production performance of a series of photo-thermal coupling catalysts and has the advantages of simplicity, convenience, cleanness, environmental protection and the like.
The invention is realized by adopting the following technical scheme:
a solar photo-thermal coupling hydrogen production device based on photocatalyst self-frequency division comprises a plurality of reflectors, an arc-shaped secondary reflector, and a heat absorption fluid layer, a photo-thermal coupling reaction layer and a vacuum layer which are sequentially arranged from inside to outside; wherein the content of the first and second substances,
the plurality of reflectors are arranged below the vacuum layer side by side, and the opening direction of the circular arc secondary reflector is downward and arranged above the vacuum layer; when the photothermal coupling reaction is carried out, a test catalyst sample is placed in the photothermal coupling reactor, the reflecting mirror collects light sources and reflects the light sources, part of the light sources is directly absorbed through the heat absorption fluid layer, part of the light sources is reflected through the circular arc secondary reflecting device and then further reflects the light sources to the heat absorption fluid layer for absorption, and the vacuum layer is wrapped on the periphery of the photothermal coupling reaction layer so as to prevent convection heat loss with air.
The invention is further improved in that the reflector adopts a linear Fresnel reflector, and the reflecting surface of the reflector can rotate according to different directions of solar radiation light.
The invention is further improved in that the test catalyst sample is placed in the photothermal coupling reaction layer in the middle of the sandwich type cylinder, and two ends of the sandwich layer at two sides are sealed.
The invention is further improved in that the device is wholly in central axis symmetry.
A further improvement of the invention is that the light source is solar radiation that strikes the surface of the earth all the year round.
In a further development of the invention, the catalyst in the test catalyst sample is capable of transmitting the infrared portion of the solar radiation and absorbing the ultraviolet and visible portions thereof.
The invention has the following beneficial technical effects:
the invention aims to provide a safe and feasible testing device for coupling light and heat physical fields for a novel photo-thermal coupling catalyst and provide a reaction site for further researching a coupling mechanism of the photo-thermal catalyst. When the photothermal coupling reaction is carried out, a test catalyst sample is placed in the photothermal coupling reactor, the reflector collects the light source and reflects the light source, part of the light source is directly absorbed by the heat absorption fluid layer, part of the light source is reflected by the circular arc secondary reflecting device and then further reflects the light source to the heat absorption fluid layer for absorption, the vacuum layer wraps the periphery of the photothermal coupling reaction layer to prevent the convection heat loss with air, and the heat absorption fluid layer is placed on the innermost layer of the whole part of the interlayer of the reactor. So that the heat of the infrared light part transmitted through the reaction fluid layer is absorbed for the reverse heating of the reactor. Therefore, in the preparation process of the catalyst, the light absorption characteristic of the catalyst is regulated and controlled by adding a cocatalyst and the like, ultraviolet light or visible light with specific frequency is accurately absorbed, an infrared light region with specific frequency is filtered, heat carried by the infrared part is transferred to a reaction device through a heat absorption fluid medium, and the purpose of experiment photo-thermal coupling hydrogen production is achieved.
Furthermore, the tested catalyst sample is placed in the photothermal coupling reaction layer in the middle of the sandwich type cylinder, and two ends of the sandwich layer at two sides are provided with seals. The reaction fluid layer is surrounded by a uniform and stable endothermic fluid layer, which can prevent the problem of test error caused by local overheating of the reactor.
Further, the linear Fresnel reflector side by side is placed under the whole hydrogen production device through photo-thermal coupling. The linear Fresnel reflector collects solar radiation light and reflects the solar radiation light to the integral part of the reactor interlayer and the arc-shaped secondary reflection device. The arc secondary reflection device further reflects solar radiation light to the upper side of the integral part of the reactor interlayer so as to ensure higher utilization rate of sunlight, and in addition, the linear Fresnel reflector condenser with low cost is adopted to reduce the production cost.
Furthermore, the whole reaction device is symmetrical about a central axis and has a stable structure.
Further, the light source is sunlight which irradiates the earth surface all the year round. Has the advantages of low cost, high efficiency and environmental protection.
In summary, according to the selective frequency division characteristics of the catalyst, the ultraviolet light part directly irradiates the surface of the catalyst through the vacuum layer to induce the semiconductor to perform the photo-catalytic reaction, the infrared light part passes through the reaction vacuum layer and the photo-thermal coupling reaction layer, the heat carried by the infrared light part is absorbed by the heat absorption fluid layer, and then the heat is reversely supplied to the photo-thermal reaction layer, so that the purpose of photo-thermal coupling is achieved. The method is clean, environment-friendly, simple and feasible, and can be stably used for testing the hydrogen production performance of the photo-thermal coupling catalyst with the self-frequency-division effect.

It should be noted that several variations and modifications of the device are possible without departing from the inventive concept. All falling within the scope of protection of the present invention
As shown in fig. 1, the invention provides a solar thermal coupling hydrogen production device based on photocatalyst self-frequency division, which comprises a linear fresnel reflector 1, a vacuum layer 2, a photo-thermal coupling reaction layer 3, a heat absorption fluid layer 4, an arc-shaped secondary reflection device 5 and a light source 6. The whole catalyst evaluation process mainly comprises the steps of firstly, obtaining a catalyst with self-frequency-division characteristics through precise regulation and control means such as a cocatalyst, uniformly mixing the catalyst with a reaction fluid, then placing the mixture on a photo-thermal coupling reaction layer 3, reflecting reflected solar radiation light to a sandwich part of a reactor by using a linear Fresnel reflector 1, absorbing an ultraviolet light region and part of visible light of the solar radiation light by using the catalyst in the reaction fluid layer, then further projecting the ultraviolet light region and part of visible light to a light absorption fluid layer, transferring heat to the heat absorption fluid to convert the heat absorption fluid into heat energy for carrying out reverse heating on the reactor, and realizing quantitative coupling of two physical fields of light and heat.
The direction of the linear Fresnel reflector 1 can be adjusted according to the specific direction at that time, so that the reflected solar radiation light is ensured to be aligned to the whole reactor device.
The precondition of the operation of the reactor is mainly based on the self-frequency-division characteristic of the prepared catalyst, so that the ratio of light to heat units absorbed by the reactor can be obtained only by clarifying the light absorption characteristic of the catalyst before the reaction. The quantitative input of the photo-heat in the photo-thermal reaction is convenient to realize, so that the photo-thermal coupling mechanism is further excavated.
