Problems solved by technology

[0007] However, ORC technology also has its inherent disadvantages: since the organic working fluid may have the characteristics of flammability and explosion, when using the residual heat of flue gas to organize ORC in the tail flue of a boiler or industrial furnace, it is necessary to consider the dust in the flue gas, etc. The leakage caused by the wear and corrosion of the heat exchanger in the channel must be considered for the resulting explosion protection and the protection of the environment and the working place.

Embodiment 1

[0036] Such as figure 1 As shown, a steam Rankine-organic Rankine combined cycle power generation device, the device includes a steam Rankine cycle, an organic Rankine cycle system, specific examples are as follows:

[0037] The steam Rankine cycle refers to the saturated steam 2 coming out of the boiler body 1, passing through the heater 3 to form superheated steam 3-1, and sending it into the steam turbine 4 to drive the steam generator 21 to generate electricity; the exhaust steam 5 coming out of the steam turbine 4 enters Condensation evaporator 10 forms condensed water 6, which is sent to boiler body 1 through condensed water pump 6-1, deaerator 7-1, feed water pump 7, and feed water heater 8, and then generates saturated steam to form steam Rankine loop loop.

[0038] The organic Rankine cycle refers to that the liquid organic working fluid 11 passes through the circulating pump 12, the regenerator 15, and the condensing evaporator 10, and the formed lean liquid return...

Abstract

The invention discloses a steam Rankine and organic Rankine combined cycle power generation device. A condenser of a steam Rankine cycle is used as an evaporator of an organic Rankine cycle. The characteristic that an organic Rankine cycle system is higher in efficiency of utilizing medium and low temperature heat sources is utilized. A large amount of latent heat of vaporization released by condensation of steam is used for organic Rankine cycle efficient power generation. More than 50 degree / ton steam can be recovered only by utilization of latent heat of vaporization of steam-Rankine cycle steam, and at the same time safety of recovery of organic-Rankine cycle smoke waste heat can be achieved, smoke discharge temperature is effectively reduced, and low-temperature corrosion of smoke can be avoided. The steam Rankine and organic Rankine combined cycle power generation device can be used for energy-saving improvement of an existing unit, also can be used for design and construction of a newly-built unit, and is remarkable in benefit of economy, society and environment protection.

Description

technical field [0001] The invention relates to a steam Rankine-organic Rankine combined cycle power generation device, specifically belonging to the technical field of thermal power plant power devices. Background technique [0002] A thermal power plant that uses water vapor as a working medium is a large-scale factory that converts thermal energy into mechanical energy, and then converts mechanical energy into electrical energy. The cycle applied in power plants is very complicated, but in essence, it is mainly completed by the Rankine cycle composed of boilers, steam turbines, condensers, water pumps and other equipment. The working principle is: the feed water is first pressurized by the feed water pump and then sent Into the boiler, the water in the boiler is heated and vaporized to form high-temperature and high-pressure superheated steam. The superheated steam expands and does work in the steam turbine and becomes low-temperature and low-pressure exhaust steam. Final...
