Low-medium temperature heat energy recovery power generation device

Abstract

The invention discloses a low-medium temperature heat energy recovery power generation device which comprises a heat exchanger, a turbine generator, a condenser and a refrigeration agent pump, wherein the heat exchanger is provided with a heat source outlet, a heat source inlet, a refrigeration agent outlet and a refrigeration agent inlet, wherein the refrigeration agent outlet is connected with the turbine generator; the turbine generator, the condenser and the refrigeration agent pump are sequentially connected with one another; an outlet of the refrigeration agent pump is connected with the refrigeration agent inlet; the heat exchanger can be used for driving turbine generator to generate electricity by vaporizing the liquid refrigeration agent by using heat of a heat source flowing through the heat source inlet; the condenser is used for condensing the refrigeration agent after the refrigeration agent pushes an impeller to rotate, and then outputting the condensed refrigeration agent to the refrigeration agent pump; and the refrigeration agent pump is used for sending the condensed refrigeration agent back to the heat source inlet. The low-medium temperature heat energy recovery power generation device can be used for generating electricity by utilizing waste low-medium temperature heat energy, and has the advantages of high energy conversion rate, good applicability and stable output.

Description

technical field [0001] The invention relates to the energy field, in particular to a device for recovering hot water energy and generating electricity in the industrial field. Background technique [0002] Energy is an indispensable resource for human survival and development, especially because the discovery, development and utilization of electricity has greatly promoted the progress of human civilization. Since then, human production and life have become increasingly inseparable from electricity, and the lack of Electricity and power shortages occur at any time in industrially developed areas. In addition to coal, oil, natural gas and other non-renewable high-level resources that can generate electricity, how to fully develop and utilize recyclable low-level energy to generate electricity has become one of the important research topics in the world today. [0003] However, existing central air-conditioning, steel, cement, petrochemical and other industrial enterprises us...

Problems solved by technology

The energy carried by these waste heat resources belongs to medium and low temperature waste heat, which is not widely used at present. In order to meet the emission standards, some of them must be cooled by blowers or water spraying, which not only wastes energy in vain, but also wastes a certain amount of electric energy and water resources.
