Abstract

The invention discloses a distributed energy island system. The system comprises a waste heat recovering system, a heat storing system and a waste heat utilizing system, wherein heat transferring oilcircularly flows through the waste heat recovering system to realize heat recovering, and thus temperature increasing is achieved; the heat is stored into a heat storing tank through the heat storingsystem; an outlet of the waste heat recovering system is connected to a heat source inlet of the heat storing system through a control valve I; a heat source outlet of the heat storing system is connected to the waste heat utilization system through a control valve III; the waste heat recovering system directly communicates with the waste heat utilization system through a control valve II. According to the system, a heat storing device is additionally arranged and used for recovering the intermittently-discharged waste heat resource and storing surplus heat and utilizing the recovered intermittently-discharged waste heat resource and the stored surplus heat to realize peak load regulation of the system and supply a stable heat source, thus a power generation system can run in a stable condition, and the system running efficiency is improved; a waste heat recovering system integrating recovering function, storing function and utilizing function is formed, and cold, heat and electricitytri-generation is realized; and a distributed energy island is formed to maximum the utilization of the waste heat resource.

Description

technical field [0001] The invention relates to an energy island system, in particular to a distributed energy island system. Background technique [0002] At present, industrial waste heat resources are abundant and have great potential for recovery. However, there are many types of waste heat sources, wide temperature ranges, scattered and unstable resources, and problems such as intermittent fluctuations and corrosion, which make the recovery of waste heat resources more difficult and the resource recovery rate is low. . Scientific use of energy refers to "use of energy according to quality and cascade utilization". In order to ensure the full and effective use of waste heat resources and ensure the continuous, stable and reliable operation of the recovery system, it is necessary to measure the heat transfer waste heat of gases and liquids at different temperature intensities according to the quantity and quality. Classify, match the best heat exchange equipment, realize...
