Problems solved by technology

[0006] However, when water-emulsion fuel obtained by mixing C heavy oil (fuel oil) and water is used in a marine diesel engine, the water-emulsion fuel drain discharged from the fuel injection pump device is collected in the fuel drain as described above. When it is in the liquid collection tank, the water-emulsion fuel drainage in the fuel drainage collection tank may be left for a long time, and the water and C heavy oil may be separated and the properties may deteriorate
As a result, there is a problem that the water-emulsion fuel drain discharged from the fuel injection pump device cannot be reused

Embodiment Construction

[0034] Below, refer to figure 1 and figure 2 One embodiment of an engine system (hereinafter, may be simply referred to as an "engine system") equipped with a water-emulsion fuel drain recycling device according to the present invention will be described. Such as figure 1 As shown, the engine system 11 includes a fuel supply device 13 , a diesel engine 14 supplied with fuel through the fuel supply device 13 , and a recycling device 12 for water-emulsion fuel drain.

[0035] The water-emulsion fuel drain recycling device 12 can return the water-emulsion fuel drain (pump drain) discharged from the drain port 16 of the fuel injection pump device 15 included in the diesel engine 14 to the fuel supply device 13. Circulation line 17.

[0036] Such as figure 1 所示,燃料供给装置13可以使贮留在第一燃料箱18内的第一燃料油和贮留在水箱19内的水在混合器20中混合得到的水乳化燃料在循环管路17中循环,并将在该循环管路17中循环的水乳化燃料供给至与该循环管路17连接的柴油发动机14。

[0037] 又,该燃料供给装置13也可以不将贮留在水箱19内的水供给至混合器20,而是仅将贮留在第一燃料箱18内的第一燃料油供给至混合器20,并使该第一燃料油在循环管路17中循环而供给至柴油发动机14。

Abstract

Disclosed is an engine system wherein used water emulsion fuel discharged from a drain port of a fuel injection pump device is returned to a circulation line after being stored for a relatively short period of time, and is reused as water emulsion fuel. An engine system (11) is provided with a circulation line (17) through which water emulsion fuel circulates; a fuel injection pump device (15) having a fuel inlet (32) to which water emulsion fuel is supplied from the circulation line (17), and a fuel outlet (41) through which the water emulsion fuel is returned to the circulation line (17); and an engine main body (29) to which the water emulsion fuel is supplied by the fuel injection pump device (15). The engine system is further provided with a used water emulsion fuel storage tank (52) for storing used water emulsion fuel discharged from a drain port (16) of the fuel injection pump device (15), and a second return line (54) and a drain charging pump (55) for returning the used water emulsion fuel stored in the drain storage tank (52) to the circulation line (17).

Description

technical field [0001] The present invention relates to a water-emulsion fuel recycling device capable of reusing water-emulsion fuel drain discharged from a fuel injection pump device for supplying water-emulsion fuel to a stationary or mobile diesel engine body, especially for ships engine system. Background technique [0002] as NO in the exhaust of internal combustion engines X A weight reduction technology that has a water-emulsion fuel obtained by mixing water with fuel oil and stirring it. This water-emulsion fuel is used as fuel for internal combustion engines to reduce NO in exhaust gas X The composition is generally recognized and may also be suitable for use in marine diesel engines. [0003] Furthermore, in this marine diesel engine, heavy oil C can be used as fuel oil, and when water-emulsion fuel is used, heavy oil C can be used as a base fuel oil. [0004] However, for example, in a marine diesel engine that uses C heavy oil that is not mixed with water as...
