Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a funnel apparatus and method using an exhaust tank inside a double bulkhead, and a vessel having the double funnel apparatus and method.

[0001] The present invention relates to a funnel device and method using an exhaust tank inside a double bulkhead, and more particularly, to a funnel device and method using an exhaust tank inside a double bulkhead, which can be utilized as an exhaust tank for collecting and discharging exhaust gas, And a funnel device using the exhaust tank inside the double partition wall.

When cargoes such as natural gas, automobiles, containers, and petroleum are transported, they are generally transported by ship considering transportation efficiency such as transportation cost and transportation time.

In order for the ship to move, a propelling device is required. The propeller plays the same role as above, and a diesel engine connected to the propeller and the shaft drives the propeller.

However, since the exhaust gas is generated during the operation of the diesel engine, a discharge pipe for discharging the exhaust gas to the outside of the hull must be formed.

In addition, when the cargo is transported to a ship, it usually takes more than a few months to cross the ocean.

Therefore, boarding passengers of the vessel should settle for accommodation in the ship for several months. In order to solve the problem, a generator for supplying electricity is required to solve the problem of the room and a discharge pipe for discharging the exhaust gas to the outside of the hull because the exhaust gas is generated during operation of the generator.

1 is a side view showing a stern portion of a conventional ship.

An engine room (10) is located below the stern section, and an upper deck (11) is located above the engine room (10). The residence (12) in which the ship 's boarders reside is located on the upper deck (11).

The residence port 12 has a total of six layers including a wheel house 13 which is located at the uppermost position and in which the traveling direction of the ship is controlled. The stern side partition wall of the cargo space 15 located at the rear end, Lt; / RTI >

A radar mast 14 for facilitating communication with the outside is located at an upper portion of the wheel house 13, and the radar mast 14 can be folded. This is to lower the height of the ship when it passes through a bridge or the like.

The engine compartment casing 16 is located on the aft side of the housing 12, and a variety of equipment such as a boiler and an exhaust device may be installed in the engine compartment casing 16.

A funnel casing 20 is disposed at an upper portion of the engine room casing 16 and is discharged from a power supply generator and a diesel engine (or steam turbine) located inside the engine room 10 of the ship at an upper portion of the funnel casing 20 A funnel 21 for discharging the exhaust gas to the outside of the hull is located. The funnel 21 is not vertically positioned but is inclined in the stern direction.

The reason why the funnel 21 is inclined in the stern direction is as follows. Firstly, the exhaust gas does not reach the residence 12 and the wheel house 13 as much as possible, thereby creating a pleasant living environment for the passengers, . Secondly, the height of the ship should be minimized so that the ship can easily pass through the bridge.

Conventionally, the funnel is disposed at the center of the upper part of the hull of the ship or slightly offset to the stern side. In this case, since the funnel is installed at a high height above the hull for smooth discharge of exhaust gas, There is a problem that the space utilization can not be reduced because it can not be stacked.
