Description

Air storage tank for starting main engine and generating engine of ship}

The present invention relates to an air storage tank, and more particularly, to an air storage tank installed in a ship and used for starting a main engine and a generating engine.

There are various ways to start a large engine, for example an engine used for driving a generator or a ship. As one example, there is a starting method of directly compressing and storing air in an air storage tank having a predetermined capacity, and then directly driving an output shaft of an engine using the compressed air.

This air storage tank plays an important role in the initial engine start-up by operating until the fuel supplied to the engine and the engine to increase the rotation speed by magnetic force.

Such an air storage tank may be installed so as to correspond to each engine, but in general, it is applicable to a system in which one air storage tank is connected to two or more large engines. In addition, the air storage tank installed in the engine body in relation to the starting air and control air of the main engine maintains pressure and also serves to supply control air and safety air.

In other words, the air storage tank plays an important role in storing and supplying the safety air and control air of the ship's engine. Especially, the air storage tank is a device that assists the engine starting and reversing operation and helps the engine operation and various solenoid valve functions. It will serve as a station and a reservoir for supplying

Hereinafter, an air compression and supply system to which a conventional air storage tank is applied to a ship will be described with reference to FIG. 1.

1 is a view illustrating an air compression and supply system to which an air storage tank connected to a main marine engine and a generating engine is applied.

As shown, the vessel is conventionally provided with a compressor 20 for compressing air, the main air storage tank 10 is connected to receive the compressed air from the compressor 20, and the main air storage The main engine 30 and the generating engine 40 which are connected to receive air from the tank 10 are provided.

As shown in the drawing, the generating engine 40 may be connected to the main air storage tank 10.

Then, the air is supplied to the main air storage tank 10 through the compressor 20 to store air at a predetermined pressure, and then the generator engine 40 and the main engine 30 are driven using the air. do.

On the other hand, there may be a deadship situation in which both the main engine 30 and the generating engine 40 are temporarily stopped while the ship is in operation.

Conventionally, when such a deadship situation occurs, predetermined air is compressed and stored in the main air storage tank 10 to operate the main engine 30 or the generating engine 40. In addition, in an emergency, after supplying air using the compressor 20 to the auxiliary air storage tank 50 provided separately, the generator engine 40 is operated to temporarily supply power to supply electric power such as a ship. This was working.

However, in the related art, the capacity of the main air storage tank 10 is small, and thus, it is difficult to operate both the main engine 30 and the generating engine 40 in the above-mentioned deadship situation. In addition, as shown in FIG. 1, even when the auxiliary air storage tank 50 is applied separately, air is supplied from the compressor 20 to supply the selected engine to the selected engine. There was a problem that was difficult.

Furthermore, in order to operate the auxiliary air storage tank 50, the crew goes through the operation of connecting the auxiliary air storage tank 50 and the compressor 20 to the field by hand and by manual method, as well as the Also, a problem arises in that a plurality of pipes (1) structure and a predetermined space in a ship are required separately for the installation of the auxiliary air storage tank.

In recent years, design constraints have also come into force in these compressed air systems under separate SOLAS (International Convention for the Safety of Life at Sea) legislation. Its main content is that if power is needed to restore propulsion, the capacity should be started with other engine devices, and the ship's propulsion should be restored within 30 minutes after the loss of power supply in the deadship. It is a provision that two or more compressed air storage tanks having a capacity that should be able to be started at least 12 times without starting the compressor during start-up.

Accordingly, in order to satisfy the SOLAS regulations as well as the above-mentioned conventional problems, it was urgent to develop an air storage tank and an air compression and supply system using the same that are easy to manage and operate.
