Description

BWTS electricity supply system{CURRENT SUPPLY SYSTEM FOR BALLAST WATER TREATMENT SYSTEM}

This technology relates to the BWTS electricity supply system.

In particular, a dedicated generator is installed on a steam-powered turbine to operate the cargo pump on ships where the cargo pump is installed, thereby producing extra electricity supplied to the BWTS, so there is no need to install additional generators and engines for the operation of the BWTS. It is about the electricity supply system.

VLCC refers to a very large crude oil carrier and is defined as over 175,000 DWT (dead weight ton: a value measured only by the weight of crude oil, excluding the weight of the ship itself) and under 300,000 DWT. These ships are equipped with ballast tanks that store or discharge seawater for a certain period of time to maintain balance.

However, it has been consistently pointed out that when seawater is stored and discharged from ballast tanks to balance the ship, new marine life is introduced into the new ocean, destroying the ecosystem.

To solve these problems, the International Maritime Organization (IMO) established the Ballast Water in 2004 to prevent and minimize risks to the environment, human health, property and resources arising from the movement of harmful aquatic organisms and pathogens. The International Convention for the Control and Management of Ships Ballast Water and Sediments was adopted, making it mandatory to install BWTS by 2017.

BWTS uses physical and chemical treatment methods to treat marine life, and electrolysis is typically used. That is, as an example, a method of destroying the cell nucleus by generating radicals (OH, HCO, O ₂ , etc.) using an electrolytic device, destroying the cell membrane through redox potential, and performing sterilization treatment, or generating oxygen or ozone Marine life is treated in a variety of ways, including injection into tubes.

BWTS is configured in various ways as above, and although the methods are different, the common feature is that electricity is inevitably required when BWTS operates.

As the installation of BWTS became mandatory, problems arose, such as having to install a separate generator to operate the BWTS or replacing the existing generator with a small capacity with a generator with a large capacity.

Here, the control switch unit includes a logic unit that is connected to the recognition supply unit to determine the amount of electricity produced by the second generator, and a switching unit that stops the operation of one of the plurality of generator engines by the logic unit. The logic unit uses the amount of electricity received by the recognition supply unit as a reference amount of electricity and operates the switching unit to stop operation of a generator engine that produces the reference amount of electricity among the plurality of generator engines.

The BWTS electricity supply system of the present invention, formed with the above configuration, produces extra electricity by utilizing a turbine that operates for the operation of the cargo pump, which is inevitably operated when the ship is at anchor, and uses the extra electricity applied to the BWTS. Since it can be produced, there is no need to replace the existing generator even if BWTS is installed.

Additionally, since at least one of the plurality of generator engines does not need to be operated due to the extra electricity produced by the turbine, maintenance time can be secured.

Figure 1 shows the BWTS electricity supply system of the present invention.

Hereinafter, an embodiment of the present invention will be described in detail through exemplary drawings. However, this is not intended to limit the scope of the present invention.

When adding reference numerals to components in each drawing, it should be noted that identical components are given the same reference numerals as much as possible even if they are shown in different drawings. Additionally, in describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

Additionally, the size or shape of components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, terms specifically defined in consideration of the configuration and operation of the present invention are only for describing embodiments of the present invention and do not limit the scope of the present invention.

Figure 1 shows the BWTS (50) electricity supply system of the present invention.

The BWTS (50) electricity supply system of the present invention produces electricity by utilizing the rotation of the turbine (30) that operates the cargo pump (40) installed on a large ship and supplies the produced excess electricity to the BWTS (50). As a result, the BWTS (50) can be operated with an existing generator, so there is no need to replace a small-capacity generator with a large-capacity generator, and when the ship is at anchor, it is not a problem even if at least one of the plurality of generator engines (70) does not operate. By doing so, it is possible to secure time to maintain the resting generator engine 70 and the generator.

The BWTS (50) electricity supply system of the present invention includes a generator engine (70), a first generator (80), a turbine (30), a cargo pump (40), a second generator (20), and a control operation unit (60). It is composed.

In the present invention, for convenience of explanation, the number of generator engines 70 will be described as three. The three generator engines 70 will be named the first generator 80 engine 71, the second generator engine 72, and the third generator engine 73, respectively.

However, it will be natural that the number of generator engines 70 is not limited to the above and can be changed depending on the user and situation.

In addition, the description will be made with three first generators 80 installed to correspond to the plurality of generator engines 70. The three first generators (80) will be named the first A generator (81), the first B generator (82), and the first C generator (83).

A plurality of generator engines 70 produce electricity by operating the first generator 80 connected to each other. Here, the generator engine 70 is an engine that can be operated with diesel, gasoline, etc.

The plurality of first generators 80 are operated according to the operation of the plurality of generator engines 70 as described above to produce electricity. The electricity produced in this way is moved to the control operation unit 60. The control operation unit 60, as will be described later, plays the same role as a switchboard and moves the supplied electricity to the BWTS (50).

BWTS (50) consists of a ballast tank, a filter, a pump through which seawater is moved, an electrolysis device, a neutralization treatment device, a control PC, a valve, an ECU (Electro-Chamber Unit), a TRO sensor unit, etc., which are integrated and interconnected. It is a device that installs seawater biological treatment equipment, temporarily stores and discharges seawater.

The control operation unit 60 is connected to each component of the BWTS 50 and serves to supply electricity, which is a power source for operating each component.

The cargo pump 40 is a plurality of pumps installed in the cargo pump room 41. The cargo pump 40 serves to unload stored crude oil when the ship is anchored.

Here, the cargo pump 40 requires an operating source to operate. The cargo pump 40 is installed on a large ship and operates by being connected to a turbine 30 driven by steam through a shaft.

The turbine 30 is operated according to the operating source to drive the cargo pump 40, or is connected to the second generator 20 to operate the second generator 20 to produce extra electricity.

In FIG. 2 of the present invention, only one second generator 20 is shown, but the present invention is not limited thereto, and a plurality of them may be installed.

Therefore, when the turbine 30 is operated, the cargo pump 40 is operated to unload the crude oil, and at the same time, the second generator 20 is operated to produce extra electricity, which is moved to the control operation unit 60 and then distributed again. and can be supplied to the BWTS (50).

The operating source of the turbine 30 may be operated for various reasons, but in the present invention, the turbine 30 is operated by steam gas.

That is, the turbine 30 receives heat energy from the boiler 10 and receives steam gas with sufficient energy supplied through the steam pipe 100, and the turbine 30 rotates by the force of the steam gas hitting the blades. It is operated by a blade that guides the turbine 30 to move from the center to the outside in the following direction.

The control operation unit 60 is connected to a plurality of first generators 80, second generators 20, and BWTS (50) and transfers electricity supplied by the first generator (80) and second generator (20) to BWTS. Power is distributed and supplied to (50), but when the second generator (20) is operated, it serves to control the operation of at least one of the plurality of generator engines (70) to stop operation.

The control operation unit 60 is more precisely composed of a recognition supply unit 61 and a control switch unit 62, and the control switch unit 62 is again composed of a logic unit 63 and a switching unit 64.

The recognition supply unit 61 is connected to the 1A generator 81, the 1B generator 82, and the 1C generator 83, receives electricity from each first generator 80, and operates the turbine 30. In this case, extra electricity generated by the second generator 20 is also supplied.

In addition, the recognition supply unit 61 supplies the supplied electricity to the BWTS (50) and distributes it to each component of the BWTS (50).

When the recognition supply unit 61 receives electricity produced from the second generator 20, it outputs a signal to the logic unit 63.

The logic unit 63 is connected to the recognition supply unit 61, and when a signal is output to the recognition supply unit 61, the switching unit 64 is operated to stop the operation of at least one of the generator engines 70. .

As an example, when the second generator 20 is operated, the logic unit 63 operates the switching unit 64 to stop the operation of the third generator engine 73 to stop the operation of the first C generator 83. Let it stop.

Through this, the third generator engine 73 and the first C generator 83 can secure maintenance time.

The logic unit 63 allows the switching unit 64 to operate using various logics.

The engine 71 for the first generator 80, the engine 72 for the second generator, and the engine 73 for the third generator may each produce different amounts of electricity.

For example, the engine 71 for the first generator 80 produces electricity in an amount equal to 10, the engine 72 for the second generator produces electricity in an amount equal to 8, and the third power generator 72 produces electricity in an amount equal to 8. If the engine 73 can produce an amount of electricity equal to 6, the logic unit 63 considers the amount of electricity supplied to the BWTS 50 and generates the engine 71 for the first generator 80, the second The switching of the generator engine 72 and the third generator engine 73 can be operated through the switching unit 64.

That is, when the ship is in operation, the BWTS (50) operates the second generator engine (72) and only needs 8 of the amount of electricity produced by the first B generator (82), and the logic unit (63) operates the first generator (82). The switching unit 64 can be operated so that the engine 71 for (80) and the engine 73 for the third generator are turned off.

In addition, if the hull is anchored and the cargo pump 40 is operated and the second generator 20 is supplying electricity in the amount corresponding to 6, the logic unit 63 receives the signal from the recognition supply unit 61. Then, the amount of electricity produced by the second generator 20 is measured, and when it is recognized that the measured amount of electricity corresponds to 6, the switch of the generator engine 70 that produces the corresponding amount of electricity uses the amount of electricity corresponding to 6 as the standard electricity amount. It can be operated to turn OFF. That is, the logic unit 63 turns off the engine 73 for the third generator through the switching unit 64, and the engine 71 for the first generator 80 and the engine 72 for the second generator The switch can be turned on to continue operating.

Through the above method, the logic unit 63 switches on the engine 71 for the first generator 80, the engine 72 for the second generator, and the engine 73 for the third generator as needed. Maximize efficiency by turning the switch off.

Although the present invention has been shown and described in relation to specific embodiments, it is known in the art that various improvements and changes can be made to the present invention without departing from the technical spirit of the present invention as provided by the following claims.
