Rankine cycle device and method thereof

Abstract

The invention discloses a Rankine cycle device comprising a boiler heater, a superheater, a turbine, a liquid storage tank, a working medium pump and a cooling device. A gas outlet of the boiler heater communicates with a gas inlet of the superheater through a gas guide pipe. A gas outlet of the superheater communicates with a gas inlet of the turbine through a gas guide pipe. The condensation device comprises a bottom plate. The top of the bottom plate is fixedly connected with a condensation box. An S-shaped condensation pipe is fixedly connected between the two sides of the inner wall of the condensation box through a fixed frame. The two ends of the S-shaped condensation pipe penetrate through the two sides of the condensation box correspondingly and extend to the two sides of the condensation box. The invention relates to the technical field of electricity generation. By means of the Rankine cycle device and the method of the Rankine cycle device, the condensation effect is greatly enhanced, steam discharged from the turbine is rapidly and sufficiently condensed, the situation that that the water steam which is not completely condensed is discharged into the liquid storage tank is well avoided, and mutual interference of a gas way and a liquid way in the whole Rankine cycle is avoided.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a Rankine cycle device and method thereof. Background technique [0002] The Rankine cycle refers to an ideal cycle process using water vapor as a working medium, which mainly includes isentropic compression, isobaric heating, isentropic expansion, and an isobaric condensation process. It is used in the power cycle of the steam plant. The water in the water pump is compressed and boosted. During the process, the flow through the water pump is relatively large. The heat dissipation of the water pump to the surrounding is equivalent to the unit mass of working fluid, which can be ignored. The reversible adiabatic compression process is called isentropic compression. The process of heating water in the boiler is originally carried out under the condition of a large temperature difference between the external flame and the working medium, and the pressure loss of the working...
