Method and device for power generating by solar energy and heat energy electricity generator

Abstract

The invention discloses a dynamoelectric method, a device and a thermal energy generator thereof by using solar energy. Liquid refrigerant in a liquid storage tank is transported to a solar energy collector by a pump, making it vaporized by solar energy to drive the thermal energy generator rotor to rotate to generate. The device has a working-circuit composed of a solar energy collector (3), a thermal energy generator (1), a condenser (14), a liquid storage tank (11) and a pump (9). The refrigerant in the circuit is the working medium. The thermal energy generator used in the invention is a double-expansion impeller generator. The refrigerant in the invention is taken as a heat carrier and has less heat released and enthalpy when condensing. The method has the advantages of solar energy utilization rate up to 40-60 percent, simple generating method, less equipment used, high generator efficiency, strong practicability and broad prospect of application.

Description

technical field [0001] The invention relates to a method and device for converting solar energy into thermal energy and then converting thermal energy into electrical energy and a thermal energy generator used in the method. Background technique [0002] Solar energy is an inexhaustible source of energy. It also has the advantages of cleanliness and environmental protection. Therefore, the utilization of solar energy has always been a hot spot in people's research on developing new energy sources. Solar power generation is an important direction of solar energy utilization. At present, there are mainly two ways for solar power generation devices. One is to use the photoelectric effect to convert solar energy into electrical energy. A solar power generation device disclosed in the patent document of Chinese Patent No. 200420015924.0, which It is to convert solar energy into electrical energy through silicon cells. In order to improve the effect, it also has an automatic track...

Problems solved by technology

Since the energy of sunlight per unit area is limited, it is necessary to use a huge concentrating device to gather light, otherwise it is difficult to obtain water vapor that meets the pressure required for the steam engine to work, which will inevitably lead to increased input costs, complex structure, and poor practicability At the same time, due to the large amount of heat released by the condensation of water vapor, the utilization rate of solar energy is low
