Abstract

The invention discloses a biomass heat energy power system based on working medium circulation condensation. The biomass heat energy power system comprises a gasification device, a turbine, a condensing unit and a one-way hydraulic pump which circularly communicate with one another sequentially through circulating pipelines. The circulating pipelines internally contain a circulating working medium. A heat collection device is installed outside the gasification device and communicates with a biomass furnace. The gasification device comprises a gasification cavity and a preheating cavity pipe. A pre-condensation cavity is arranged at the exhaust port position of the turbine, and the preheating cavity pipe makes parallel contact with the pre-condensation cavity. The biomass heat energy power system based on working medium circulation condensation can accelerate condensation, improve the efficiency of the turbine and reduce the heat energy exhaust amount, and therefore the heat energy conversion efficiency is improved.

Description

technical field [0001] The invention belongs to the field of energy utilization equipment, in particular to a biomass thermal energy power system based on working medium circulation condensation. Background technique [0002] Energy is an important material basis for the survival and development of human society. Throughout the history of the development of human society, every major progress of human civilization is accompanied by the improvement and replacement of energy. The development and utilization of energy has greatly promoted the development of the world economy and human society. [0003] However, with the continuous development and consumption of energy, non-renewable energy sources such as petroleum, coal mines, and natural gas are gradually reduced, and energy conservation and recycling are gradually being valued. The basic content of my country's current energy strategy is: adhere to the priority of conservation, based on domestic, diversified development, r...
