Problems solved by technology

[0007] However, the common problems of existing thermal power generation equipment are: a. The temperature requirements for high-temperature heat sources are high, generally above 200°C, and the thermal energy conversion efficiency is low, and the thermal energy conversion efficiency is generally 15% to 35%; b. The heat displacement of the condensing device is large, and the waste of heat energy is large. The condensation speed through the natural condensation method is slow, and the active condensation method (fan air cooling or liquid pump water cooling) requires additional power consumption; c. The turbine is prone to leakage of working fluid Problems; d. Turbine speed is unstable, and it is prone to stuck problems; e. The heat collection effect of the heat collector is not good, and the external waste heat absorption rate is small; f. The gasification temperature of the working medium is unstable, and the condensation effect of the working medium is not good , the working medium is easy to deteriorate or appear impurities; g. The existing equipment is relatively large

Abstract

The invention discloses a fuel gas heat energy power system based on pressurizing condensation. The fuel gas 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 fuel gas heat supplying furnace. The fuel gas heat supplying furnace comprises a fuel gas inlet, an air inlet, a mixed gas combustion chamber and an igniter. The condensing unit comprises a condenser pipe, a heat dissipation fan and a pressurizing mechanism. The pressurizing mechanism is installed at the middle end of the condenser pipe. The pressurizing mechanism comprises a pressurizing turbine and a turbine pressure regulator, and the turbine pressure regulator is connected with the pressurizing turbine in a control manner. The fuel gas heat energy power system based on pressurizing condensation has a high condensing rate, can reduce the condensing exhaust energy and improve the heat energy conversion efficiency and is stable in running and adjustable in power.

Description

technical field [0001] The invention belongs to the field of energy utilization equipment, in particular to a gas heat energy power system based on pressurized 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, rely on science and tec...
