Abstract

The invention relates to a steam turbine and organic Rankine cycle fluid turbine dual-drive combined electricity generation or mechanical working equipment. The equipment is driven by a turbine expander, which distributes two different working media respectively through a converging type cylindrical gear box and cantilever structures for two input shafts, and transmits electricity or directly works through an output shaft. After passing through a steam turbine to enable the steam turbine to run to work, an organic Rankine cycle heat source, namely saturated steam, enters an evaporator to exchange heat with an organic working medium, then the organic working medium enters a working medium turbine to enable the working medium turbine to run to work, and finally the organic working medium returns to a condenser to finish an internal cycle through a working medium pump; and after exchanging heat with the organic working medium in the evaporator, the heat source steam returns to a cooling tower and then passes through a waste heat boiler or directly passes through the waste heat boiler to finish an external cycle. According to the equipment, a steam cycle system not only plays a role in utilizing a high-grade heat source but also plays a role in adjusting hear source parameter and improving the heat exchange efficiency of the evaporator, and an organic Rankine cycle plays a role in further utilizing a low-grade heat source to save energy and protect environment.

Description

technical field [0001] The invention is applicable to the field of waste heat utilization of steam turbine and organic Rankine cycle equipment, specifically relates to power generation or work output of steam turbine and organic Rankine cycle equipment, and is a core power module of steam turbine and organic Rankine cycle equipment. Background technique [0002] At present, the utilization rate of low-quality heat sources in China is not high, resulting in a large waste of energy, which does not conform to the current macroscopical situation of energy conservation and environmental protection at home and abroad; at this stage, the domestic use of low-quality heat sources mainly uses screw expanders and organic Rankine cycle systems to generate electricity. Among them, the core power module of the organic Rankine cycle power generation equipment is also divided into two types, namely the screw machine and the centripetal turbine; due to the structure of the screw machine and t...
