High temperature efficient ground solar steam generating set

Abstract

The invention discloses a high temperature efficient ground solar steam generating set, comprising a water pump, a water tank component, a steam turbine, a generator and a system control circuit. The generating set is characterized by also comprising a condenser component, a heat exchanger component, a thermal storage box component, an oil pump, a temperature control valve, a water level control water tank component and a base component. The generating set in the invention has the advantages of reasonable structure, low carbon, environment protection, high temperature and high efficiency, low cost, convenient installation and maintenance, safety and reliability, greatly saves land resources, and can be built in the areas at the classes of 1-5 in which national solar resources are distributed.

Description

technical field [0001] The invention relates to a steam power generation device, in particular to a high-temperature and high-efficiency solar steam power generation device on the ground. Background technique [0002] Because the higher the temperature, the higher the heat has the higher utilization value. In thermodynamics, we call the thermal energy with higher temperature as "high-grade" energy. Example: Pentane (C 5 h 12 ), gasoline, hydrogen, electricity, friction energy, etc., the common feature of these energy sources is that they can reach extremely high temperatures when they are applied; on the contrary, for those heat energy with very low temperature, they are called "low-grade" energy, or " "Waste heat" (for example, the heat recovered from the cooling water of the cooling tower of the electric heating plant can only be used for domestic hot water), and its use is limited. Conventional solar water heaters produce hot water below 100°C for heating, but cannot...

Problems solved by technology

[0009]In recent years, thin-film batteries such as cadmium sulfide, gallium arsenide, and copper indium selenide have been developed, which will save the cost of monocrystalline silicon manufacturing and reduce power consumption, but the photoelectric conversion efficiency is only 6 %---10%, and the cost of its production environment is too high (grain is relatively scarce; arsenic is poisonous, and the production investment is large; the photoelectric conversion efficiency of cadmium sulfide is low by about 3.5%)
