Description
Technical Field
The invention belongs to the technical field of photo-thermal power generation, and particularly provides a thermochemical heat storage hot electron power generation device.
Background
With the continuous progress of science and technology and the continuous consumption of earth resources, people are enthusiastically researching various renewable resource utilization methods; among them, solar energy is the most abundant carbon neutral renewable energy source on the earth, and has been the focus of research on renewable energy utilization technologies. Conventionally, existing solar photo-thermal power generation technologies all receive solar radiation through a light collector, and then convert solar energy into electric energy by using a thermoelectric conversion device. Meanwhile, according to different thermoelectric conversion modes, the existing solar photo-thermal power generation technology is mainly divided into three types of traditional thermal cycle power generation technology, thermoelectric power generation technology and thermal electron power generation technology.
Further, the conventional thermodynamic cycle power generation technology is to convert solar energy into mechanical energy and then convert the mechanical energy into electric energy to realize power generation, and mainly comprises three power generation modes of Stirling cycle power generation technology, rankine cycle power generation technology and Brayton cycle power generation technology. The thermal electron power generation technology mainly converts solar energy into electric energy by taking electrons excited by solar energy as an energy transmission medium, and has good continuous power generation capacity, and only needs to perform static movement in the power generation process, so that the thermal electron power generation technology can realize power generation without moving parts. In the thermal electron power generation technology, the electron generation mode mainly comprises a thermal induction thermal electron emission technology and a photon enhancement thermal electron emission technology.
Specifically, the thermally induced thermionic emission technique is capable of directly absorbing focused solar radiation and converting it into thermal energy, such that free electrons in the cathode are thermalized to escape the cathode surface and are emitted into vacuum, and finally overcome the space charge barrier to be received by the adjacent anode, thereby converting solar energy into electrical energy. Compared with the heat-induced electron emission technology, the photon-enhanced thermionic emission technology can more efficiently utilize solar radiation; further, photon-enhanced thermionic emission techniques can employ semiconductors to absorb super-bandgap photons in solar radiation to generate photogenerated electrons, while excess energy and sub-bandgap photons in solar radiation can also be absorbed and converted to thermal energy to thermalize the electrons and cause them to escape from the cathode surface for projection to the anode. However, the use of existing photon-enhanced thermionic emission techniques still has a number of drawbacks; for example, existing power generation devices are susceptible to the intensity of solar radiation when generating electricity using photon-enhanced thermionic emission techniques; in other words, the temperatures of the cathode and the anode in the existing photon enhanced hot electron power generation device are easily affected by the intensity of solar radiation, so that the generation, transportation and reception of electrons are affected, and the stable output of electric energy is seriously affected.
Accordingly, there is a need in the art for a new thermochemical thermal storage thermoelectric power generation device to address the above problems.

The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to the specific circumstances.
The problem that the power generation efficiency of the existing hot electron power generation device is easily affected by the intensity of solar radiation is solved; specifically, in the existing photon enhanced hot electron power generation device, the power generation device can use a semiconductor to absorb super bandgap photons in solar radiation so as to generate photo-generated electrons; at the same time, the surplus energy in the solar radiation can be absorbed and converted into heat energy by the power generation device, so that electrons are thermalized and can escape from the surface of the cathode to be projected to the anode. However, the existing photon enhanced hot electron power generation device has a plurality of defects in the operation process; for example, the power generation device is easily affected by the intensity of solar radiation when generating power by using photon-enhanced thermionic emission technology; further, the intensity of solar radiation affects the temperatures of the cathode and anode in the power generation device, thereby affecting the generation, transportation and reception of photo-generated electrons, and further severely affecting the stable output of electric energy. In order to solve the above problems in the prior art, the present invention provides a new thermochemical heat-storage thermal electron power generation device comprising a thermal electron power generation module and a thermochemical heat storage element connected to the thermal electron power generation module; the thermal electron power generation assembly can convert heat energy into electric energy and output the electric energy, the thermal chemical heat storage element can convert solar energy into chemical energy for storage, and when the intensity of solar radiation changes, the thermal chemical heat storage element can perform heat exchange with the thermal electron power generation assembly, so that the working temperature of the thermal electron power generation assembly is effectively stabilized, and the thermal chemical heat storage thermal electron power generation device can stably output electric energy.
The structure and operation of a first preferred embodiment of the thermochemical thermal-electric power generation apparatus of the invention will be described with reference to fig. 1 and 2; wherein FIG. 1 is a first schematic illustration of a first preferred embodiment of a thermochemical heat-storage thermionic power generation device of the invention and FIG. 2 is a second schematic illustration of a first preferred embodiment of a thermochemical heat-storage thermionic power generation device of the invention. Specifically, the thermochemical heat-storage thermoelectron power generation device of the present invention comprises a thermoelectron power generation module and a thermochemical heat-storage element 2 connected to the thermoelectron power generation module. The thermal electron power generation assembly can convert heat energy into electric energy, so that the thermochemical heat storage thermal electron power generation device can generate electric energy; meanwhile, the thermochemical heat storage element 2 can convert solar energy into chemical energy for storage, when the intensity of solar radiation changes, the thermochemical heat storage element 2 can exchange heat with the hot electron power generation assembly, so that the working temperature of the hot electron power generation assembly is stable, the problem that the power generation efficiency of the traditional hot electron power generation device is easily influenced by the intensity of solar radiation is effectively avoided, and the thermochemical heat storage hot electron power generation device can be further ensured to stably output electric energy to a great extent.
Further, as shown in fig. 1 and 2, in a first preferred embodiment of the thermochemical heat-storage thermoelectron power generation device of the invention, thermochemical heat-storage element 2 is able to absorb solar radiation so that its own temperature is raised in order to convert solar energy into chemical energy for storage. Meanwhile, chemical energy stored in the thermochemical heat storage element 2 can generate heat through reversible reaction and is transferred to the thermal electron power generation assembly in a heat conduction and heat convection mode, so that the working temperature of the thermal electron power generation assembly is effectively stabilized.
