Description
Technical Field
The invention relates to the technical field of solar energy storage, in particular to a high-density solar energy storage and continuous energy supply system.
Background
Solar energy is a green and environment-friendly renewable energy source, and is widely applied to the fields of photoelectric energy conversion, light-heat energy conversion, artificial photosynthetic energy conversion and the like by human beings. Generally, due to the difference of solar radiation indexes of different geographical positions of different areas, the solar radiation energy deviation is large under different seasons, and the solar radiation index is far higher than that in winter in summer in the northern hemisphere. And people need to use cold far more than the demand of using heat in summer, under the ordinary condition, can utilize solar energy drive refrigeration cycle to satisfy and use cold demand in summer, but to the winter because solar energy irradiation index is low, hardly satisfy the demand of using heat again. Therefore, a feasible approach to solve the main contradiction is to design a high-density solar energy storage system, which can convert solar energy into heat energy for storage in the whole year. The system is mainly used for storing energy in summer, releasing partial heat energy simultaneously to prepare and meet the demand of cold consumption, and is mainly used for releasing energy in winter to prepare and meet the demand of heat consumption, and simultaneously stores partial solar heat energy, so that the system can continuously operate in the whole year range and realize continuous energy supply.
Solar thermal energy stores three main technical routes: sensible heat storage, latent heat storage, and thermochemical storage. Sensible heat storage due to the difference between the stored heat medium and the ambient temperature, the sensible heat storage must store the heat energy from the sun using buried insulation or thermal insulation material laid down. The Chinese invention patent of patent application publication No. CN105841360A introduces 'a solar medium temperature heating system based on cross-season water body heat storage', the system adopts water body sensible heat storage, because the specific heat of water is lower, the energy density is low and the occupied area is large by adopting sensible heat storage, and buried heat preservation is needed to be adopted to reduce the sensible heat temperature difference loss, and the heat storage unit investment cost is high. Compared with sensible heat storage, latent heat storage has higher storage energy density, and latent heat storage temperature can cover high-temperature, medium-temperature and low-temperature areas, but the temperature range of stored heat is smaller and is mainly limited by a phase change balance point of a heat storage material. In addition, the phase change material for latent heat storage generally has a low thermal conductivity, and the release process of stored energy needs a larger heat transfer area or a heat transfer temperature difference to be realized, thereby reducing the heat transfer efficiency. The Chinese invention patent of patent application publication No. CN103712255B introduces a seasonal solar energy-phase change energy storage graded energy release heating system and a method, the system and the method adopt a phase change heat storage material, solar energy is stored in the phase change material in summer, and solar energy is released from the phase change heat storage device in winter. The system does not introduce a heat dissipation control method of the phase change heat accumulator in detail, and key core technical points such as the energy density of the phase change heat accumulator are mainly characterized by occupying area and heat energy conversion efficiency of the phase change heat accumulator, so that the practical application of the system is limited. Thermochemical storage is the highest energy density, stores and releases energy through chemical reactions among different gas-solid, solid-solid and solid-liquid substances, has almost no heat dissipation loss because the energy is mainly stored in molecular chemical bonds of materials, is a technical route with great commercial prospect in the future, and is still at the research and test stage at present in the maturity of relevant core technologies. Chinese invention patent publication No. CN102705997A describes "a solar thermochemical adsorption seasonal efficient energy storage device and method", which stores solar thermal energy by adsorption chemical reaction in summer and releases stored solar energy by chemical desorption in winter for heating. The technology adopts the adsorption type chemical reaction to store solar energy, has the advantages of high storage density, small heat dissipation loss and the like, the system designs a cooling tower, a high-pressure evaporator/condenser and a low-pressure evaporator/condenser, and the heat of the high-temperature heat storage condenser in winter is used as the heat source of the low-temperature heat release evaporator, so the design really improves the energy storage density at low temperature, but when the system does not use heat in summer, the heat of the high-temperature heat storage condenser needs to be released to the environment through the cooling tower, and the whole energy utilization efficiency is equivalently reduced.

The following describes the functions of the high-density solar energy storage and continuous energy supply system:
first, store the solar energy
After the solar photon energy is converted into heat energy by the vacuum heat pipe type solar heat collector 1, the heat energy is transferred to the adsorbing material in the fixed bed adsorption chemical reaction heat reservoir 2 through the cooling fluid, the adsorbing material is heated and then undergoes desorption chemical reaction, the reaction process is a heat absorption process, one part of the absorbed heat is used for breaking partial chemical bonds in molecules on the original adsorbing material, so that partial atoms in the molecules of the adsorbing material are in an excited state, and the chemical reaction energy barrier of the molecules is in a low-order state, thereby providing a precondition for the next step of energy release; the other part of the heat is stored in the desorbed gas, the desorbed gas is driven by natural pressure difference to enter a condenser in a vacuum state in the integrated condensation evaporator 3, the desorbed gas is cooled by cooling water and then condensed into a liquid from a gas state, and the other part of the absorbed heat energy is released to the cooling water.
When the system is ready to operate in a solar heat storage mode, the heat storage water pump 12 is started in sequence, the vacuum heat pipe type solar heat collector 1 heats circulating water, the water temperature is gradually increased, when the water temperature is increased to 180 ℃, the electromagnetic three-way valve 9 of the water outlet pipeline of the annular heat exchange pipe group of the heat reservoir is opened, the fixed bed adsorption chemical reaction heat reservoir 2 is in a heating state, desorption chemical reaction begins to be carried out in the reaction heat reservoir, the electromagnetic stop valve 11 of the heat storage pipeline of the heat reservoir is opened, the evaporation water pump 13 and the electric stop valve 19 of the condenser inlet are opened, the condenser is started to operate under a cooling working condition, and the water drainage pump 26 of the separator is started to drain water to the evaporator. When the water level in the evaporator is higher, the steam trap pump 16 of the evaporator is started, and simultaneously the water level regulating valve 17 of the evaporator is opened, so that the excess water in the evaporator is conveyed to the water storage heat exchanger 4 of the thermocline. According to the mass transmitter arranged on the fixed bed adsorption chemical reaction heat reservoir 2, when the mass transmission data is stable and unchanged, namely the fixed bed adsorption chemical reaction heat reservoir finishes the heat storage process, the fixed bed adsorption chemical reaction heat reservoir is switched to another fixed bed adsorption chemical reaction heat reservoir 2 according to the operation mode, and the starting control sequence strategy is repeated. After the heat storage process of one fixed bed adsorption chemical reactor is finished, the cooling demand can be provided for users.
Secondly, release energy
Liquid fluid in the evaporator in the integrated condensation evaporator 3 passes through low-temperature water in the thermocline water storage heat exchanger 5, is heated and evaporated under the vacuum condition. Then enters a fixed bed chemical adsorption reaction heat reservoir 2 through a connecting pipeline to perform an adsorption chemical reaction with adsorption material molecules in an excited state in the heat reservoir. The adsorption chemical reaction is a heat release process, a part of released heat is recombined by a part of chemical bonds in the molecules of the adsorption material in the reaction process, after the adsorption material releases energy, a part of atoms in the molecules are in a metastable state, and the energy barrier of the chemical reaction of the molecules is in a high-order state, so that a precondition is provided for the next step of energy absorption. Another part of the heat is the latent heat released by the gaseous sorbents during the sorption process.
