Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] figure 1 Shown is the solid particle packed bed air heat absorber of the present invention. The heat absorber is composed of quartz glass tube bundle 1, solid particles 2, cold air header 3, hot air header 4, cold air inlet 5 and hot air outlet 6. The quartz glass tube bundle 1 is composed of a plurality of quartz glass tubes. The diameters of the quartz glass tubes can be the same or different, and the arrangement of the quartz glass tubes can be sequential or crossed. The arrangement form and quantity of the quartz glass tube bundles 1 are determined by the characteristics of the input concentrated radiation energy flow 7, and the principle is to ensure that all the concentrated radiation energy flows 7 put into the heat absorber are composed of solid particles 2 and composed of quartz glass The multiple quartz glass tubes of tube b...

Abstract

The invention relates to a solid particle accumulation bed-type air heat absorber for a solar thermal power station, which consists of a quartz glass tube bundle (1), solid particles (2), a cold air collection box (3), a hot air collection box (4), a cold air inlet (5) and a hot air outlet (6). The quartz glass tube bundle (1) consists of a plurality of quartz glass tubes; the solid particles (2) are accumulated inside the quartz glass tubes of the quartz glass tube bundle (1), and keep a stationary state in the working process; the cold air collection box (3) is positioned in the lower part of the quartz glass tube bundle (1) and is in sealed connection with the lower part of the quartz glass tube bundle (1); the hot air collection box (4) is positioned in the upper part of the quartz glass tube bundle (1) and is in sealed connection with the upper part of the quartz glass tube bundle (1); the cold air inlet (5) is positioned on the cold air collection box (3); and the hot air outlet (6) is positioned on the hot air collection box (4). According to the invention, high temperature air at the temperature of 700 DEG C to 1,300 DEG C and the normal pressure or the pressure of over 1MPa can be obtained, and meanwhile, sensible heat per se is used for heat accumulation.

Description

technical field [0001] The invention relates to an air heat absorber for a solar thermal power station. Background technique [0002] Solar energy is an inexhaustible renewable energy source. Today, as fossil fuels are decreasing year by year and the international energy situation is becoming increasingly severe, the development and utilization of solar energy is one of the important ways to realize the diversification of energy supply and ensure energy security. The basic principle of the tower thermal power generation device is to use many heliostats to reflect solar radiation to the solar receiver placed on the tower, and generate superheated steam or high-temperature air with the help of heating medium to drive the generator set to generate electricity. The high temperature solar heat absorber is the core component of the tower thermal power generation system. Many studies have been carried out on this technology abroad, mainly in the United States, Spain, Germany, Isra...
