Problems solved by technology
[0002] The marine diesel engine will produce a large amount of hot smoke when it is working, and the direct discharge of a large amount of hot smoke will take away a large amount of unused heat energy, which results in the incomplete utilization of the capacity of the marine diesel engine during normal operation
[0003] In addition, in order to ensure the safe operation of diesel engine cylinders, it is necessary to cool them with cooling water, but the cylinder liner cooling water will be discharged directly, and the remaining heat cannot be effectively used. Since the cylinder liner cooling water takes away the heat of the diesel engine system, the The overall efficiency of energy utilization is further reduced

The invention discloses a multifunction device of shipping diesel engine waste-heat utilization. The multifunction device includes a first heat exchanger, a second heat exchanger, a third heat exchanger, a four heat exchanger, a first cooler, a second cooler, a first circulating pump, a second circulating pump, a third circulating pump, an air conditioner system, an under-floor heating system, a sea water desalination device, a first circulation loop, a second circulation loop and a third circulation loop, wherein the second circulation loop sequentially passes a circulation loop formed by a first cool water outlet, a second hot water inlet, a second hot water outlet, a parallel pipeline, a fourth hot water inlet, a fourth hot water outlet, a sixth hot water inlet, a sixth hot water outlet, the second circulating pump and a first cool water inlet in a communication mode; and the third circulation loop sequentially passes a circulation loop formed by a third cool water outlet, the thirdcirculating pump, the sea water desalination device, a third cool water inlet in a communication mode. According to the multifunction device of the shipping diesel engine waste-heat utilization, thesmoke generated by a diesel engine and waste heat of cylinder sleeve cooling water can be effectively utilized, and the fresh water resource, heat supplying and the like which are necessary for livingare provided for workers in a ship.
Description
technical field [0001] The invention relates to the technical field of energy saving of internal combustion engines, in particular to a multifunctional device for utilizing waste heat of marine diesel engines. Background technique [0002] The marine diesel engine will produce a large amount of hot smoke when it is working, and the direct discharge of a large amount of hot smoke will take away a large amount of unused heat energy, which results in the incomplete utilization of the normal working capacity of the marine diesel engine. [0003] In addition, in order to ensure the safe operation of diesel engine cylinders, it is necessary to cool them with cooling water, but the cylinder liner cooling water will be discharged directly, and the remaining heat cannot be effectively used. Since the cylinder liner cooling water takes away the heat of the diesel engine system, the The overall efficiency of energy utilization is further reduced. Contents of the invention [0004] T...
