Power generation system using desert temperature difference energy

Abstract

The invention aims to provide a power generation system using desert temperature difference energy. The power generation system comprises a heat storage module, a cold accumulation module, a separator, a turbine and a generator, wherein the heat storage module is built and piled up through heat storage bricks, the heat storage bricks comprise heat storage materials, heat storage brick heat exchange pipes are evenly installed in all the heat storage bricks in the heat storage module in a penetrating and inserting mode, the heat storage bricks are filled with sand, and the heat storage brick heat exchange pipes are in uniform contact with the sand; the cold accumulation module is similar to the heat storage module in structure; the separator, the turbine, cold accumulation brick heat exchange pipes, a medium circulating pump and the heat storage brick heat exchange pipes are sequentially connected; an outlet of each heat storage brick heat exchange pipe is connected with the separator; and the generator is coaxially connected with the turbine. Efficient and reasonable utilization of desert heat can be reasonably achieved according to the change condition of heat resources in a desert area, the heat of sand on the surface layer is absorbed and stored through the heat storage module, the cold energy of a deep desert is stored through the cold accumulation module, the turbine is blown by media to drive the power generator to generate electricity, and reasonable utilization of the desert temperature difference energy is achieved.

Description

technical field [0001] The invention relates to a power generation system, specifically a desert power generation system. Background technique [0002] Areas such as deserts and Gobi have sufficient sunshine for a long time, and the heat resources on the surface of the desert are very rich. During the daytime, the surface temperature of the desert is generally around 50 to 70°C. At present, the main way to utilize solar energy in desert areas is to lay a large number of solar photovoltaic panels in desert areas to convert solar energy in desert areas into electrical energy. Reasonable planning and use is still a problem. [0003] The temperature at a depth of 5 meters underground in the desert is about 10°C, and the underground temperature may even drop below 0°C at night. Therefore, using the sand temperature difference between the desert surface and the deep underground to generate electricity is an effective means of using desert energy to generate electricity.
