Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 Shown is a tubular solid particle heat absorber with a helically rotating inner insert in Example 1 of the present invention. The heat absorber is composed of an insert fixing structure 1 , a spiral rotating insert 3 , solid particles 4 and a quartz heat absorbing tube 5 . A solid particle inlet 2 is opened above the quartz heat absorbing tube 5 , and a solid particle outlet 6 is opened below the quartz heat absorbing tube 5 . The insert fixing structure 1 is located directly above the quartz heat absorbing tube 5. The spiral rotating insert 3 is connected to the insert fixing structure 1 through a rigid or flexible suspension connection, and its function is to fix the spiral rotating insert 3 on the quartz absorber. The inside of the heat pipe 5. During operation, the solid particles 4 fall freely inside the quartz heat-abso...

Abstract

A tubular solar heat absorber provided with an insert and solid particles comprises a quartz heat absorbing tube (5), the solid particles (4), the insert (3) and an insert fixing device (1), wherein a solid particle inlet (2) is formed in the upper part of the quartz heat absorbing tube (5), and a solid particle outlet (6) is formed in the bottom of the quartz heat absorbing tube (5); the insert fixing device (1) is located right above the quartz heat absorbing tube (5), and the insert (3) is connected with the insert fixing device (1) in a mode of rigid connection or flexible suspending connection and is fixed in the quartz heat absorbing tube (5); the solid particles (4) freely fall off inside the quartz heat absorbing tube (5) during working. According to the tubular solar heat absorber provided with the insert and the solid particles, the retaining time of the solid particles (4) in the quartz heat absorbing tube (5) can be prolonged, so that the high-temperature solid particles (4) are obtained.

Description

technical field [0001] The invention relates to a tower type solid particle heat absorber for solar thermal power generation. Background technique [0002] Due to the increasing depletion and soaring prices of fossil energy such as oil and natural gas, traditional thermal power generation has gradually lost its original status; and with the development of nuclear power technology, there have also been nuclear leaks in places such as Fukushima in recent years, which not only hinder It affects the safety of our electricity use and also threatens the safety of our lives and property. In this case, solar thermal power generation technology is undoubtedly a relatively safe, reliable, energy-saving and environmentally friendly power generation method. [0003] The heat absorber is the key component to realize light-to-heat conversion in solar thermal power generation. The thermal performance of the heat absorber will directly affect the thermal efficiency of the solar heat collec...
