Water circulation power generation system for energy recovery

Abstract

A water circulation power generation system for energy recovery includes at least one water circulation power generation system connected to a heat exchange system to obtain required water for a heat exchange process. The water circulation power generation system includes a water tank to store cooling water, a water supply pipeline and a recovery pipeline. The water supply pipeline draws water from the water tank to supply front end water to the heat exchange system. The recovery pipeline guides operational circulation water discharged from the heat exchange system and has a hydraulic power generator installed thereon driven by the operational circulation water to convert kinetic energy thereof to electric power. Thus during the operational circulation water flows to its recovery destination, its kinetic energy drives the hydraulic power generator to produce additional electric power.
