Thermal dynamic power generation device adopting solar pond

Abstract

The invention discloses a thermal dynamic power generation device adopting a solar pond and belongs to renewable energy using equipment. The top of the solar pond is covered with arc-shaped Fresnel lens condensers, inside of the solar pond is divided into an upper cavity, a middle cavity and a lower cavity through an upper sunlight transparent partition board and a lower sunlight transparent partition board, blackened heat absorption layers are arranged on the bottom wall and peripheral side walls of the lower cavity, a Freon annular evaporator and an electric heater are assembled in the lower cavity, the Freon annular evaporator communicates with a steam turbine and a condenser, and the upper cavity, the middle cavity and the lower cavity are fully filled with clear water respectively through water supplementing ports. According to the device, low-temperature thermal energy collected and stored by the solar pond is taken as thermal dynamic to heat Freon which is a working medium with low boiling point, Freon is vaporized, the steam turbine is pushed to drive a generator to generate power, and the device has the characteristics of being simple in structure, low in construction cost and power generation cost, convenient to control, reliable to use and easy to industrialize.

Description

technical field [0001] The invention belongs to renewable energy utilization equipment, and mainly relates to a solar power generation device. Background technique [0002] There are two existing solar power generation methods: one is to use photovoltaic power generation to manufacture solar cells; the other is to use photothermal power generation to build solar power stations. Solar photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to convert sunlight energy into electrical energy. The most basic components of solar photovoltaic power generation are solar cells (sheets), including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. At present, solar photovoltaic power generation has been widely used in various fields, but the cost of photovoltaic power generation is too high to compete with conventional energy generation, and it can only be commercialized with national policy subsidies...

AI Technical Summary

Problems solved by technology

This kind of thermal power generation can be divided into four forms: tower thermal power generation, trough thermal power generation, disk thermal power generation, and strip thermal power generation. The tracking is complicated, the construction investment is large, and the cost of power generation is high. The investment is 5-6 times higher than that of ordinary thermal power plants. It is not economically cost-effective and has not been commercialized so far.
