Power circulation system for power generation

Abstract

The invention relates to a power circulation system for power generation. An implementation method of the power circulation system comprises the following steps of: with power generated by a low-temperature heat source and wind energy as a power source, pumping water in a bottom water pool to a head water pool by using a piston type water pump driven by the power source, and carrying out power generation by virtue of a hydroelectric generator when the water in the head water pool flows into the bottom water pool, and therefore the problem of incapability of network access because multiple energy sources are used for generating power together and power generation of some energy sources are uncontrollable is solved. The technical problem that the low-temperature heat source generates power is solved, the structures of an evaporation chamber, a condensation chamber and a piston are optimized by using a low-temperature evaporation theory; and therefore the power circulation system is suitable for occasions with low-temperature heat sources, such as solar energy, optothermal, terrestrial heat and waste heat of waste gases, and allows heat source power generation about 100 DEG C.

Description

[0001] 1. Technical field: [0002] The present invention relates to a power cycle system for generating electricity. 2. Background technology: [0003] In the case of a heat source, the commonly used power generation method is the Rankine cycle, which consists of four main devices: a water pump, a boiler, a steam turbine and a condenser. The water in the Rankine cycle is compressed and boosted in the water pump; then it enters the boiler to be heated and vaporized until it becomes superheated steam, and then enters the steam turbine to expand and do work, and the low-pressure steam after work enters the condenser to be cooled and condensed into water. Return to the water pump to complete a cycle. This method requires the temperature of the heat source to be relatively high, usually above 500°C. When the temperature is lower than this temperature, the efficiency will drop. At this time, the Karina cycle is generally used. This method is technically the same as the Rankine c...
