Abstract

The invention discloses a pump-free Rankine cycle and liquid metal combined power generation system which comprises an adsorption-Rankine cycle power generation cycle module and a liquid metal magnetofluid power generation cycle module. The adsorption-Rankine cycle power generation cycle module comprises a generator, an expansion machine, an adsorption bed a, an adsorption bed b and an aeration pipe; and the liquid metal magnetofluid power generation cycle module is composed of an annular channel structure and liquid metal. The adsorption beds alternately work to replace a working medium circulating pump, the input power of the working medium circulating pump can maximally account for 45% of the output power of the expansion machine, the working medium circulating pump is eliminated, the energy consumption of the system is reduced, and the net output power of the system is improved. The outlet pressure of the expansion machine in the adsorption-Rankine cycle is reduced through the adsorption process of the adsorption beds, and the net output power of the system is further improved. The temperature of the liquid metal in the annular channel structure is more uniform, and the flow ofthe liquid metal is facilitated.

Description

technical field [0001] The invention belongs to the technical field of waste heat power generation, in particular to a combined power generation system of a pumpless Rankine cycle and liquid metal. Background technique [0002] With the increasing energy crisis and environmental pollution, low-grade energy utilization technology has attracted more and more attention. Chinese patent CN205558983U discloses "A Combined Power Generation System of Rankine Cycle and Liquid Metal Natural Circulation", which can convert various forms of heat energy into electrical energy. However, the system uses a working fluid circulation pump to complete the circulating flow of the working fluid, which reduces the net output power of the system. This greatly affects the economics of the system. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention is to design a pumpless Rankine cycle combined power generation system with liq...
