Abstract

The invention belongs to the field of energy source application and mainly relates to a Rankine cycle power generation system capable of realizing efficient utilization of heat energy. The system is the Rankine cycle power generation system with a reversible Carnot cycle subsystem, namely a heat regenerator is additionally arranged between a Rankine cycle working medium pump and a steam generator, and one reversible Carnot cycle system is composed of the Rankine cycle power generation system, the heat regenerator, a compressor, an expansion valve and a condenser by a heat regeneration medium and a pipeline; the reversible Carnot cycle system has the function of conveying a lot of the heat energy, which is brought away by a cooling medium in the condenser, is discharged and is absorbed by the system in a current Rankine cycle, back to the working medium of the Rankine cycle by the heat regeneration medium, so that the thermoelectric conversion rate is extremely improved.

Description

technical field [0001] The invention relates to a Rankine cycle power generation system with a reverse Carnot cycle subsystem, which belongs to the field of energy application, in particular to the field of new energy application. Background technique [0002] Low-temperature thermal energy below 150 °C widely exists in nature and industrial production processes, such as solar energy, biomass energy, geothermal energy, and industrial waste heat from cement plants, thermal power plants, and chemical plants. Therefore, it is of great significance to use this part of heat energy safely, reliably and efficiently. Compared with the traditional water vapor Rankine cycle power generation system, the organic Rankine cycle (ORC) power generation system using low-boiling organic medium has high power generation efficiency, environmental friendliness, simple structure and high reliability, and has become the first choice for recycling low-temperature heat energy. best choice. Rankin...
