Problems solved by technology

[0005] The tower system is a solar focused alkali metal power generation system that uses a solar mirror as a heliostat and focuses multiple solar reflectors on an alkali metal power generation device. The utilization time of the solar mirror is only 4-6 hours. For example, the solar mirror on the east side of the tower is basically unusable in the morning and can only be used after noon or afternoon, so the efficiency of solar energy collection is low. This technical solution can realize high-temperature collection , but usually its size is large, not suitable for small or home systems

Abstract

The invention relates to solar focusing utilization, and particularly adopts point focusing solar lenses to collect solar energy and be applicable to a fixed point array solar focusing alkali metal power generation system. The system comprises at least one or a group of point focusing solar lenses, at least one alkali metal power generation device and a tracking control device, wherein the solar lenses are arranged on a solar lens support, the alkali metal power generation device is arranged in a dotted area which is focused by the solar lenses and above or below the solar lenses, the focal lengths of the solar lenses are varied in a solar tracking process and kept in the dotted area of the alkali metal power generation device all the time; and the tracking control device controls the solar lenses to focus sunlight on at least one alkali metal power generation device when the sunlight varies, the solar photovoltaic cell panel does not move with the solar lenses and is maintained statistic relative to the ground when the solar lenses track the solar energy, so that the solar tracking and focusing utilization is achieved.

Description

technical field [0001] The invention relates to the utilization of solar energy, in particular to a point-focused solar mirror to realize solar energy collection, and a point-focused converter to realize the focus tracking and focus alkali metal power generation system of solar energy. Background technique [0002] Alkali metal thermoelectric conversion is a new technology for direct conversion of thermoelectric energy using the ionic conductivity of Al2O3 solid electrolyte, using sodium or potassium as the working medium, and using the process of thermally regenerated concentration difference battery as the working principle. Alkali Metal Thermal to Electric Converter (AMTEC) is an area-type power generation device. It has no moving parts, no noise, and no maintenance. The heat sources are combined to form a modular combined power generation device, which can meet the requirements of different capacity loads, and the thermoelectric conversion efficiency can exceed 30%.
