The invention relates to a non-azeotropic working medium organic Rankine cycle system with the component dynamic state being adjustable. The non-azeotropic working medium organic Rankine cycle systemcomprises an evaporator, an expansion machine, a condenser, a working medium storage tank and a working medium pump which are connected cyclically and sequentially in the working medium flowing direction. A gas-liquid separation branch with a main gas-liquid separator is further connected between the evaporator and the expansion machine in parallel. A bottom liquid outlet of the main gas-liquid separator is further connected into a pipeline between the expansion machine and the condenser through a pipeline. A component separation branch is further lead behind an outlet of the condenser and isconnected between the working medium storage tank and the working medium pump. The component separation branch comprises a component separation device and a subcooler. A feeding opening of the component separation device is connected with the outlet of the condenser and an inlet of the subcooler through a light component outlet, and a heavy component outlet is further connected into a pipeline between the condenser and the working medium storage tank. Compared with the prior art, according to different operation working condition characteristics, the components of a non-azeotropic mixed working medium in the system can be adjusted in real time, and the temperature matching effect of two heat exchanger sides is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of power engineering and relates to a non-azeotropic organic Rankine cycle system with dynamically adjustable components. Background technique [0002] The sharp increase in energy consumption worldwide has drawn more and more attention from governments and all walks of life to efficient utilization technologies of various renewable energy sources and medium and low temperature waste heat. Organic Rankine Cycle (ORC) is one of the important technologies for utilizing medium and low temperature heat sources, which can be effectively applied in geothermal energy, biomass energy, medium and low temperature solar heat collection, industrial waste heat recovery and other fields. From the perspective of technological innovation, since the ORC system uses low-boiling-point organic working fluid instead of water / steam for thermal cycle, it can not only significantly reduce the final discharge temperature of waste he...
