Description
Technical Field
The invention belongs to the field of solar light-gathering and heat-collecting utilization, and particularly relates to a positive displacement solar heat absorber which absorbs heat by adopting transparent grids and spheres and exchanges heat with a gas working medium.
Background
Solar energy is clean, environment-friendly and widely distributed renewable energy, and the development and utilization of solar energy resources are one of important ways for realizing energy structure upgrading and assisting the aims of carbon peak reaching and carbon neutralization in China. For example, solar energy is developed and utilized to perform high-temperature heat supply or thermal power generation, and the technology is generally realized by adopting a condenser consisting of a large-area reflector to gather low-density sunlight into a small cavity heat absorber and absorb the low-density sunlight by a heat absorber in the heat absorber, so that high temperature is generated to heat a heat transfer working medium, and the conversion of solar energy to working medium heat energy is realized; then, heat is supplied to the outside through the hot working mediums, or a heat engine (such as a steam turbine engine) is pushed to do work to drive a generator and produce electric energy. Whether medium-high temperature heat supply or high-grade solar photo-thermal power generation is utilized, the solar heat absorber is always the core device of the system, and the light-heat conversion performance and the operating temperature of the system directly influence the operating efficiency and the economical efficiency of the whole solar photo-thermal utilization system.
Because the working temperature of the air medium is not limited (can be more than 1000 ℃), the air medium does not have the problems of high-temperature decomposition (generally within 500 ℃) and low-temperature freezing and the like fused salt and heat conducting oil for solar photo-thermal, and the air medium is very convenient and cheap to obtain. Therefore, a positive displacement solar heat absorber using air as a heat transfer medium is one of important forms of solar high-temperature heat utilization. In the prior art (such as the publication No. CN103123175B and the patent No. ZL 201610803966.8), the positive displacement solar heat absorber generally comprises an outer cylinder in the shape of a cavity, a heat absorber made of a porous medium material and installed inside the outer cylinder, and a glass cover plate fixed at the front end opening position of the sealed cylinder and used for transmitting sunlight collected by a condenser to form a closed cavity; the heat absorber absorbs the gathered solar energy, air enters the cavity from the air inlet pipe on the side of the sealing cylinder body close to the glass cover plate, and then flows out along the air outlet pipe at the tail end of the sealing cylinder body after being heated by the heat absorber. In actual work, because the penetration distance of sunlight in the porous medium is very small, the main high-temperature areas are on the exposed surface layer, which causes serious infrared radiation heat loss; in addition, the existing porous medium heat absorber has insufficient heat storage capacity, and the heat storage capacity of the heat absorber is limited. Therefore, the traditional porous medium volumetric heat absorber concept is abandoned, and an integrated solar heat absorber with large heat storage capacity, high-efficiency light-heat conversion and low heat loss is invented and created, and is particularly important for improving the economic performance of a solar concentrating thermal power station.
