A desert hot air circulation power generation device

Abstract

The invention discloses a desert hot wind cycle power generation device. A heat reservoir is ellipsoidal and is fixed to an arc heat gathering board through a fixing frame; light reflecting materials are laid on the inner wall of the arc heat gathering board; the arc heat gathering board is fixed in sand through a support; the surface of the heat reservoir is made of a black wrapping iron sheet; the two ends of the heat reservoir are connected with a cold reservoir through an upper air pipe and a lower air pipe; the cold reservoir is in a prolate ellipsoid shape and is laid in the position 3 meters below the surface sand; generator sets are arranged in the upper air pipe and the lower air pipe and in the positions, located in the sand, of the upper air pipe and the lower air pipe. The desert hot wind cycle power generation device is simple in structure, low in manufacturing cost, and capable of emitting high-quality stable current in a harsh desert environment; as the power generation device is closed, the influence of the outer variable windy and dusty environment on the interior is small relatively; the temperature of the heat reservoir is higher through the additional arrangement of the arc heat gathering board; the cold reservoir is laid in the sand and the sand has the good heat dissipation effect, so that the situation of a big up and down temperature difference is formed very easily, larger wind cycle drives the generator sets to operate, and the energy utilization rate is effectively increased.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a desert hot air circulation power generation device. Background technique [0002] The development and utilization of new energy has been paid more and more attention by the society, especially the development and utilization of wind energy, solar energy and other renewable meteorological energy with large energy storage capacity, pollution-free and renewable is receiving a new round of attention. [0003] my country has many large deserts dominated by temperate desert climates, with a total area of ​​about 600,000 square kilometers, of which the Taklamakan Desert accounts for half of China's desert area, which is 337,600 square kilometers. At noon in the desert, the ground temperature often reaches 70°C. And such a high temperature can be achieved only by relying on strong solar radiation. In desert areas, the sun shines for more than 3,000 hours a year, and in many ...

Problems solved by technology

However, the conversion rate of photovoltaic power generation is low, the equipment production process consumes high energy, and the pollution is large; wind power generation is greatly affected by wind instability and seasons, the utilization hours are not high, storage is difficult, and it will also face peak and frequency modulation in actual transmission problems and issues affecting power system stability
