Heat-energy recovery unit

热能回收装置

Abstract

The utility model relates to a heat energy recovery device, in particular to a device used for recovering the heat energy in waste hot water. The utility model comprises a sink, a plurality of cavity bodies that are arranged in the sink and pipe coils that is arranged in cavity bodies. Adjacent cavity bodies are mutually communicated, the pipe coils in adjacent cavity bodies are connected in series, a heat resource inlet and a heat source outlet are respectively arranged at the two ends of the sink, a medium outlet is arranged on the pipe coil of the heat resource inlet end, a medium inlet is arranged on the pipe coil of the heat resource outlet end. The utility model divides the sink horizontally into a plurality of mutually communicated areas; pipelines are arranged at the areas for exchanging medium, the flow direction of the medium opposites to that of the waste hot water. Thus, a certain temperature gap forms between the cavity bodies from which the medium enters and the cavity bodies from which the medium leaves, the temperature at the rear end is highest and the temperature at the inlet end is lowest, the medium is heated adequately in every area and is further heated when going into the next area because the environment temperature there is generally higher than the medium temperature and finally flows out the device until the highest temperature is reached. The utility model has the advantages of good heating stability and high heat exchanging efficiency.
热能回收装置。涉及一种回收废热水中热能的装置。它由水槽、设在水槽中的若干腔室、设在腔室中的盘管组成,相邻的腔室连通,相邻腔室中的盘管串接,水槽的一端设热源进口,另一端设热源出口,介质出口设在热源进口端的盘管上,介质进口设在热源出口端的盘管上。本实用新型将水槽横隔为多个相互连通的区域,在各区域内设交换介质的管道,介质流动方向和废热水流向相反;这样,从介质进入的腔室到介质离开的腔室,各腔室间形成了一定的温度差,在尾端的温度最高,进入端的温度最低,介质在每个区域能被充分地加热,到下个区域时,环境温度整体高于介质温度,介质进一步被加热,直至达到最高温度流出本装置。本实用新型的加热稳定性好,换热效率高。
