Abstract

The invention discloses a solar-optothermal-groove-type large-opening double-layer parabola high-efficiency collector. The collector comprises a tripod main beam, a plurality of condenser units and a heat-collecting pipe, wherein the plurality of condenser units are fixed on the tripod main beam side by side, and the light-gathering focal point of each condenser converges on the heat-collecting pipe; each condenser unit comprises a pair of outside condenser and inside condenser which are mutually arranged at interval, and an airflow channel is formed between the outside condenser and the inside condenser. The collector provided by the invention mainly utilizes the techniques such as, a parabola light-gathering principle, strong torsibility of a tripod welding frame main beam, high precision of a parabolic mould pressing and improvement on the wind resistance grade of the collector through changing the wind loading somatotype coefficient of the collector, so that the collector provided by the invention has the advantages of high light-condensing precision, high heat collection efficiency, strong wind resistance capability and low power station whole construction cost.

Description

technical field [0001] The invention relates to a solar photothermal trough-type large-opening double-layer parabolic high-efficiency heat collector. Background technique [0002] At present, as a new type of clean energy, solar energy has been widely used in various industries. Among them, the use of solar energy for power generation has become a new energy hotspot due to its green and pollution-free advantages. Following the mature development of photovoltaic power plants, solar thermal power plants are now becoming more mature and gradually entering the market. Parabolic trough collectors have been maturely used in photothermal power stations. However, most of the opening lengths of parabolic trough collectors are 5770mm and 6770mm for medium and high temperature power plants. If the size of the parabolic opening of the heat collector is increased, the temperature of the heat collecting tube in the heat collector will be higher, which is more conducive to improving the...
