Description

Fuel supply device of inert gas generator

(Technology)

The present invention relates to a fuel supply device for an inert gas generator, and more particularly to an inert gas generator for supplying an inert gas to the cargo oil tank to prevent explosion due to the flammable gas present in the cargo oil tank of the ship. It relates to a device for supplying the fuel required for this.

(Background)

In ships with tanks for storing oil, such as drilling vessels or tankers, evaporation gas is generated from oil stored in cargo oil tanks, and the generated evaporation gas remains in the air layer in the tank, where external air enters. This is a dangerous condition with considerable explosives. Therefore, in such ships, a device is used to forcibly fill inert gas to prevent external air from entering the cargo oil tank, thereby eliminating the risk of explosion due to the evaporation gas of the cargo oil.

In such a system, an inert gas for filling a cargo oil tank is produced using exhaust gas generated by combustion of fuel. In other words, after cooling the exhaust gas generated by fuel combustion by spraying water, and removing various impurities contained in the cooled exhaust gas by filtering, the inert gas is often replenished into the cargo oil tank by an inert gas blower. The core device of such an inert gas generator is a scrubber that burns fuel and cools and filters exhaust gases.

2 is a schematic view of a vessel schematically showing a fuel supply device of a conventional inert gas generator. As shown, the scrubber 120 of the inert gas generator is installed in the superstructure 110 of the vessel 100, and the fuel for initial ignition of the scrubber 120 is the fuel installed in the scrubber itself. It is supplied from the fuel tank 131 provided in the engine room 130 using the pump 121.

However, the supply of the fuel for the initial ignition of the scrubber 120 is the fuel tank 131 of the engine room 130 because the fuel pump 121 for this is present inside the scrubber 120 located in the superstructure 110. You can't use it directly up from it. That is, since the height difference between the fuel pump 121 of the scrubber 120 located in the superstructure 110 and the fuel tank 131 located in the engine room 130 reaches approximately 10-20 m in most tankers. , Direct fuel supply is not possible due to the lack of suction power of the screwdriver fuel pump 121.

Therefore, the fuel supply apparatus of the conventional inert gas generator is provided with a separate auxiliary fuel tank 122 in the adjacent portion of the scrubber 120, and primarily by using the large fuel pump 132 of the engine room 130. The fuel is supplied from the fuel tank 131 to the auxiliary fuel tank 122, and the fuel is supplied from the auxiliary fuel tank 122 using the fuel pump 121 of the screwer 120 again. .

As such, the fuel supply device of the conventional inert gas generator is a structure in which the auxiliary fuel tank 122 and the fuel pump 121 of the scrubber 120 itself are required, and thus the device is complex in its entirety. There is a problem that is occupied.

Accordingly, an object of the present invention is to solve the problems of the conventional fuel supply device of the inert gas generator, and to increase the space utilization and cost of the ship by simplifying the components for supplying fuel to the inert gas generator. To achieve savings.

An object of the present invention described above is to supply fuel from a fuel tank of an inert gas generating device to supply fuel to a scrubber installed in a superstructure from a fuel tank installed in an engine room of a ship. A fuel pump is provided in the engine room, and the fuel pump is achieved by a fuel supply device of an inert gas generator, characterized in that for supplying fuel directly to the scrubber from a fuel tank installed in the engine room.

Hereinafter, with reference to the accompanying drawings will be described in detail the fuel supply device of the inert gas generator according to the present invention. The following embodiments are merely illustrative of the fuel supply device of the inert gas generating device according to the present invention, it is not intended to limit the scope of the present invention.

1 is a schematic view of a vessel schematically showing a fuel supply device of an inert gas generator according to the present invention. As shown, the fuel supply device of the inert gas generator according to the present invention, the fuel tank 11 is installed in the engine room 10 of the vessel 1 and the scrubber 30 is installed on the superstructure 20. Applied to inert gas generators.

According to the feature of the present invention, the fuel pump 31 for supplying fuel from the fuel tank 11 of the engine room 10 located in the lower portion to the screwer 30 located in the upper portion is provided in the screwer 30 itself. It is not provided but is separated from it and installed in the lower engine room 10, and does not use a separate auxiliary fuel tank as in the prior art for temporarily storing fuel pumped from the fuel tank 11.

That is, when the fuel pump 31 is installed in the upper screwer 30, even if the fuel cannot be sucked from the lower fuel tank 11, the fuel pump 31 is provided in the lower engine room 10. In this case, the same horsepower pump can push up the fuel sufficiently, thus eliminating the need for an auxiliary fuel tank.

With the configuration in which the auxiliary fuel tank is omitted, the fuel pump 31 for supplying fuel to the scrubber 30 is not directly passed through the auxiliary fuel tank from the fuel tank 11 installed in the engine room 10 without having to go through the screwer 30. ) Fueled.

By omitting the auxiliary fuel tank, it is not necessary to install various measuring devices, valves and actuators related to the auxiliary fuel tank, thereby reducing the related costs and using the space occupied by the auxiliary fuel tank for other purposes. Thus, the space of the ship can be used more efficiently.

According to the fuel supply apparatus of the inert gas generator according to the present invention described above, the component equipment for supplying fuel to the inert gas generator can be simplified to increase the space utilization of the vessel and reduce the cost.
