Abstract

The invention discloses a solar water-working-medium cavity-type heat absorber, and belongs to the technical field of light-condensation solar thermal power generation devices. The heat absorber comprises a gas supplying unit, a heat exchanging unit and a cavity. The gas supplying unit comprises a CO2 gas storage tank connected with the cavity, a gas pump is further arranged on a pipeline connected with the cavity, a first valve is arranged at an exhausting opening of the CO2 gas storage tank, and a second valve is arranged at a gas inlet of the cavity. The heat exchanging unit comprises a heat exchanger connected with the cavity, the heat exchanger is communicated with an exhausting pipeline of the CO2 gas storage tank through a bypass pipeline, and a bypass valve is arranged on the bypass pipeline. An air discharging valve and a CO2 gas discharging valve are arranged at the top of the cavity. Greenhouse gas is sufficiently utilized, a novel utilization mode which saves energy and reduces emissions is adopted, and the heat absorber is reasonable in structural arrangement and easy to obtain and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of concentrating solar thermal power generation devices, and in particular relates to an improved solar hydraulic mass cavity heat absorber. Background technique [0002] Due to the continuous consumption of fossil fuels and the improvement of national environmental awareness, solar thermal power generation has attracted global attention. At present, there are mainly three types of concentrating solar thermal power generation (CSP), tower type, trough type and dish type thermal power generation. Among them, the tower type solar thermal power generation system is favored because of its high focusing ratio, large-scale power generation and high power generation efficiency. Wide attention at home and abroad. The basic principle of the tower solar thermal power generation system is to use the heliostat matrix to focus the solar energy into the heat absorber placed high in the sky, and the working medium absorbs...
