Solid block line focused solar heating heat transfer system

Abstract

The utility model aims to provide a solid grain block line focusing solar energy heating and heat transmitting system. A group of solar energy focusing heat energy acquisition system consists of a line focusing solar energy lens, a light transmitting tube, transmission devices, solid grain blocks, a heat accumulator and a power unit, wherein the light transmitting tube is arranged at a solar energy irradiating part of the line focusing solar energy lens; a heat-insulating tube is arranged at a non-irradiating part of the line focusing solar energy lens; the light transmitting tube is connected with the heat-insulating tube; the transmission devices are arranged in the light transmitting tube or the heat-insulating tube; the solid grain blocks are arranged on the transmission devices, and driven by the power unit to move inside the light transmitting tube; the solid grain blocks are heated by the solar energy focusing heat energy acquisition system; and the heated solid grain blocks are transmitted to the heat accumulator arranged on the ground through the transmission devices so as to finish the heat energy acquisition and heat transmission. The solid grain block line focusing solar energy heating and heat transmitting system can realize heat acquisition and transmission with high temperature, large scale, low cost and high efficiency, and is suitable for work at the temperature of 10 to 1500 DEG C.

Description

technical field [0001] The invention relates to the utilization of solar thermal energy, especially the heating, heat transfer and utilization of line-focused solar energy. Background technique [0002] In the field of solar energy, molten salt is used to store heat. Although molten salt can achieve high temperature storage, it needs heat energy to heat it because it needs to be transformed from solid to liquid. At the same time, there are problems with the toxicity, economy, and safety of molten salt. , so the use of molten salt heat storage is limited. [0003] In the field of solar energy, air or other gases are also used for heat storage, but their thermal fusion is small, and large-scale thermal energy storage cannot be realized.
