The invention relates to the technical field of ships, and discloses a ship double-circulation heating system which comprises a heating device, an inner circulation pump and a mixing barrel which are sequentially arranged and communicated through a pipeline to form an inner circulation loop of a heating medium. The heating device and the internal circulating pump are arranged in a marine engine room; the ship double-circulation heating system further comprises an outer circulation pump and an energy consumption part, the mixing barrel, the outer circulation pump and the energy consumption part are communicated through a pipeline to form an outer circulation loop for medium circulation, and the mixing barrel, the outer circulation pump and the energy consumption part are arranged outside a ship engine room. When the outer circulation loop breaks down, the inner circulation loop can also operate normally, and therefore operation of the heating device is safe. In the using process, the heated chemicals generate toxic and harmful gas, due to the fact that the inner circulation loop and the outer circulation loop operate independently, the toxic and harmful gas can be prevented from entering a cabin, and therefore the safety performance is improved.

    本发明涉及船舶技术领域,公开了一种船舶双循环加热系统,船舶双循环加热系统包括依次设置的加热装置、内循环泵及混合筒,加热装置、内循环泵及混合筒通过管路连通形成加热介质的内循环回路,加热装置和内循环泵设置于船舶机舱内;船舶双循环加热系统还包括外循环泵及耗能部件,混合筒、外循环泵及耗能部件通过管路连通形成介质流通的外循环回路,混合筒、外循环泵和耗能部件设置于船舶机舱外。当外循环回路发生故障时,内循环回路也可以正常运行,这样对于加热装置的运行来说比较安全;使用过程中加热的化学品产生有毒有害气体,由于内循环回路和外循环回路单独运行,能够避免有毒有害物质进入到机舱内,从而提高了安全性能。
