Organic Rankine cycle system experimental device

Abstract

The invention provides an organic Rankine cycle system experimental device. The organic Rankine cycle system experimental device takes organic matter as cycle fluid to absorb heat of a heat source, and a generated high-temperature high-pressure gas working medium acts by means of mechanical expansion so as to drive an electric generator to generate electricity. The organic Rankine cycle system experimental device comprises a pressurizing device, a heating device, an electricity generating device and a cooling device which are in pipeline connection sequentially. The organic Rankine cycle system experimental device has the advantages that the device is small, movable and convenient to mount and demount; since a small-sized vortex expander is adopted, pipeline connection is improved and relevant parameter setting is optimized, the device can be used for teaching experiments and fills the gap of teaching experiments and practical training of a domestic ORC (organic Rankine cycle) system.

Description

technical field [0001] The invention relates to a teaching experiment device, in particular to an organic Rankine cycle system experiment device. Background technique [0002] At present, the root cause of my country's grim energy situation lies in the low energy efficiency. my country's output efficiency per ton of standard coal is only equivalent to 10.3% of Japan's and 28.6% of that of the United States. Nearly 60-65% of industrial energy in my country is transformed into waste heat resources, among which low-temperature waste heat below 350°C accounts for about 60% of the total waste heat. Efficient recycling. [0003] Organic Rankine Cycle (Organic Rankine Cycle, ORC) is a Rankine cycle with low-boiling point organic matter as the working medium. It is mainly composed of waste heat boiler (or heat exchanger), turbine, condenser and working medium pump. The organic working medium absorbs heat from the waste heat flow in the heat exchanger to generate steam with a certa...

Problems solved by technology

The research in Part 3 is currently more focused on component modeling and experimental verification, and the introduction of related objects is relatively small. At the same time, there has always been a situation where theories are divorced from reality in teaching research. Students only know the theoretical knowledge of the ORC cycle, and there is no suitable one at present. Teaching experimental device to do corresponding experiments for students
