A solar thermal power generation heat absorption system

Abstract

The invention discloses a heat absorption system for solar thermal power generation, comprising: a support platform; a floating device filled with gas with a density lower than air; a heat absorption device fixedly connected to the bottom surface of the floating device; a lifting device for controlling the heat absorption device The ascent and descent of the heat absorber; the ascending pipe connected to the inlet of the heat absorber; the descending pipe connected to the outlet of the heat absorber. Wherein, both the ascending pipe and the descending pipe are telescopic parts; the rising buoyancy of the floating device is at least greater than the sum of the gravity of the floating device, the gravity of the heat absorbing device, the gravity of the lifting device, the gravity of the ascending pipe, and the gravity of the descending pipe. Because the floating device is used to hang the heat absorbing device in the air, and then the rising height of the floating device is adjusted through the upgrading device, the heat absorbing device can be installed at high altitude without the support of the heat absorbing tower, and the height of the heat absorbing device can be adjusted according to the actual situation Height, not affected by the structure of the absorber tower.

Description

technical field [0001] The invention belongs to the design field of solar thermal power generation, in particular to a solar thermal power generation heat absorption system. Background technique [0002] While the economy continues to develop, energy is increasingly in short supply, traditional non-renewable energy is increasingly exhausted, and economic development is increasingly constrained by the development and utilization of energy. The utilization of renewable energy has attracted widespread attention, especially the utilization of solar energy has attracted more attention from the world. [0003] Solar thermal power generation is a major way of utilizing solar energy at present. At present, solar thermal power generation can be divided into tower solar thermal power generation, trough solar thermal power generation, and dish solar thermal power generation according to the solar energy collection method. [0004] In the field of solar thermal power generation, tower-...

AI Technical Summary

Problems solved by technology

As we all know, the large mass at the top is very detrimental to the lateral performance of the structure, and due to the requirements of the process, there are strict requirements for the control of the displacement of the top of the heat absorbing tower, which cannot be treated according to ordinary towering structures

The heat absorption tower technology of the existing tower solar thermal power generation system generally adopts the heat absorption tower of the steel frame structure, the concrete structure or the mixed structure of the concrete and the steel frame structure, and its height is limited by the structure and cost of the heat absorption tower, so it is difficult to achieve very high
