Description

Automatic day-by-day concentrating photo-thermal reaction device Technical Field The invention belongs to the technical field of photocatalytic reaction devices, and particularly relates to an automatic day-by-day concentrating photo-thermal reaction device. Background The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. With the increasing global demand for clean energy, solar energy is an important energy utilization form of renewable energy, and is widely applied in the fields of photo-thermal power generation, photovoltaic power supply, photochemical conversion, photo-thermal catalysis and the like. The concentrating structure is used as a key component of the solar energy utilization system, and has the core function of concentrating sunlight dispersed in a certain receiving area to a target receiving area (such as a photovoltaic cell, a photo-thermal absorber and a photo-thermal catalytic reactor), so that the light energy density and the irradiation intensity of the target area are obviously improved, and the energy utilization efficiency of the system is further improved. Therefore, the dynamic adjustment capability and the condensation accuracy of the condensation structure directly determine the upper limit of the energy capturing efficiency and the overall operation performance of the solar energy utilization system. At present, the light-gathering structure in the industry is mainly divided into three types, namely a fixed type, a single-axis tracking type and a double-axis tracking type according to the number of motion degrees of freedom, and various structures have certain technical bottlenecks and performance limitations in the aspects of light-gathering efficiency, tracking precision and environmental adaptability. For example, the fixed type light condensing structure has a fixed light condensing angle, and cannot be adjusted along with day-night alternation or seasonal variation of solar azimuth angle (east-west direction) and altitude angle (north-south direction). The solar energy concentrating device has high concentrating efficiency only in short time intervals of fixed solar positions such as noon, the concentrating deviation is large in other time intervals, the efficiency is suddenly reduced, and the solar energy concentrating device can not be used normally almost in high-latitude areas or seasons alternately, so that serious solar energy resource waste is caused, and the application scene is severely limited. Taking the emerging field of solar driven photo-thermal catalysis (such as fuel preparation by hydrogenation of CO 2 driven by solar energy, degradation of organic pollutants, and the like) as an example, the scene has higher requirements on the stability, the light intensity uniformity and the continuous energy supply capability of a light condensing system. The traditional fixed or low-precision tracking system is difficult to maintain the high-temperature and high-light intensity environment required by the reaction, so that the catalytic efficiency is low and the reaction is discontinuous, and the high-cost double-shaft tracking system limits the popularization and application of the light focusing structure in the distributed and mobile photo-thermal catalytic device. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide an automatic sun-by-sun concentrating photo-thermal reaction device, which realizes real-time detection and automatic tracking of solar azimuth by cooperatively controlling a photo-tracking sensor and a servo motor and combining an electric cylinder auxiliary support and a two-axis turntable linkage adjustment mechanism, improves the concentrating efficiency to more than 80%, provides stable and high-strength photo-thermal cooperative input for a photo-thermal catalytic reactor, realizes efficient capturing and utilization of sunlight, reduces the manufacturing cost and maintenance difficulty, and is particularly suitable for photo-thermal catalysis, photo-thermal power generation and distributed solar energy utilization scenes.
