Abstract

PURPOSE: An energy-saving ship is provided to reduce operation costs and fossil fuel consumption by using the propulsion of the ship and the discharge energy of a pump. CONSTITUTION: An energy-saving ship comprises a tunnel, a cooling water pump and a by-pass pipe. The cooling water pump operates while the ship is at sea. The by-pass pipe is installed on the outlet side of the cooling water pump. The tunnel is mounted on both sides of the ship and guides the seawater. A generator(2) is mounted inside the tunnel. Electricity is produced by using the seawater flowing in the tunnel. A propeller(1) and the generator are installed on the by-pass pipe.

Description

Energy Saving Ship {Energy Saving Ship}

선박에서 소비되는 여러 가지 에너지를 수력발전장치를 이용하여 전력으로 변환하여 선박에서 전력 생산에 사용되는 화석에너지의 사용을 감축시키는 기술Technology that reduces the use of fossil energy used to produce electricity in ships by converting various energy consumed in ships into electric power by using hydroelectric generator

관내를 유동하는 유체의 유동에너지를 축류 또는 횡류 수차(1)를 이용하여 회전에너지로 변환하여 축류수자에 연결된 발전장치를 통해 전력을 생산하는 수력 발전기술Hydroelectric power generation technology that converts the flow energy of the fluid flowing in the pipe into rotational energy using the axial or cross-flow aberration (1) to produce electric power through the generator connected to the axial flow water

선박은 대양을 항해하는 동안 필요한 모든 동력을 자체에서 생산하여 소비하여야 한다. 이를 위해 선박에서는 추진력을 얻기 위한 추진장치와 선박에서 사용되는 전력을 생산하기 위한 발전장치를 갖추고 있다. 선박에서 사용되는 추진장치와 발전장치는 다양한 형태가 있지만, 선박에 사용되는 추진장치와 발전장치의 공통점은 석유, 천연가스 등과 같은 화석연료를 연소하여 에너지를 얻는다는 것이다.The ship shall produce and consume on its own all the power necessary during the voyage of the ocean. To this end, ships are equipped with a propulsion device for obtaining propulsion and a power generation device for producing electric power used in the ship. There are various types of propulsion and power generation devices used in ships, but the commonality between propulsion devices and power generation devices used in ships is to obtain energy by burning fossil fuels such as petroleum and natural gas.

화석연료를 연소하게 되면, 이산화탄소와 같은 온실가스가 발생하게 되어 지구온난화의 원인이 된다. 또한 최근의 유가의 급격한 상승으로 인해 선박 운항비용의 상당부분을 차지하는 화석연료의 구입비용을 증가하여 선박의 운항 경제성이 현저하게 떨어지고 있는 실정이다.When fossil fuels are burned, greenhouse gases such as carbon dioxide are generated, which causes global warming. In addition, due to the recent sharp rise in oil prices, the cost of purchasing fossil fuels, which account for a large portion of the operating cost of the ship, has increased, leading to a significant decline in the ship's operating economy.

선박은 일반적으로 시속 30km 내지 50km의 속도로 운항하며, 도2에서와 같이 운항하는 선박의 선체에 선박의 진행방향에 적합한 터널을 형성시키면, 선박의 진행속도와 동일한 속도로 해수가 터널 속으로 유입되게 된다. 도1과 같이 터널 내부에 해수의 속도에너지를 회전에너지로 변환할 수 있는 수차(1)를 설치하고 회전에너지를 전기에너지로 변환할 수 있는 발전장치(2)를 설치하면, 선박의 추진을 위해 소모되는 추진력의 일부를 전기에너지로 회수할 수 있다. 또한 선박의 도3에서 나타낸 바와 같이 선박의 주기관과 발전기관이 운전되는 동안에는 냉각수펌프(3)가 항상 운전되어야 하며, 도4에서와 같이 냉각수펌프(3)의 출구측에 펌프로 부터 토 출되는 해수의 유동에너지를 전기에너지로 변환할 수 있는 수차(1)와 발전장치(2)를 설치하면 냉각수를 순환시키기 위해 소모되는 에너지의 일부를 전기에너지로 회수할 수 있다.The ship generally operates at a speed of 30km to 50km per hour, and if a tunnel suitable for the direction of the ship is formed in the hull of the ship as shown in Fig. 2, seawater flows into the tunnel at the same speed as the ship's traveling speed. Will be. As shown in FIG. 1, if the aberration 1 for converting velocity energy of seawater into rotational energy is installed inside the tunnel, and the generator 2 for converting rotational energy into electrical energy is installed, Part of the thrust consumed can be recovered as electrical energy. In addition, as shown in FIG. 3 of the ship, the coolant pump 3 should always be operated while the main engine and the generator tube of the ship are operated, and as shown in FIG. 4, the pump discharges from the pump to the outlet side of the coolant pump 3. By installing the aberration 1 and the power generation apparatus 2 capable of converting the flow energy of the seawater into electrical energy, some of the energy consumed to circulate the cooling water can be recovered as electrical energy.

선박의 추진력으로 소모되는 에너지와 냉각수펌프(3)와 같이 선박 운항시에 운전되는 펌프를 구동하기 위해 소모되는 에너지를 회수하여 전기에너지로 변환하게 되면, 선박에서 사용되는 전기에너지를 생산하기 위해 운전되는 발전기관의 운전량을 감소시킬 수 있으며, 발전기관의 운전량을 감소시키면 화석연료를 적게 사용하게 되어, 온실가스의 발생량을 감축시킬 수 있으며, 선박 운항비용을 절감할 수 있다.When the energy consumed by the propulsion of the ship and the energy consumed to drive the pump operated during the ship operation, such as the coolant pump (3) is recovered and converted into electrical energy, it operates to produce the electrical energy used in the ship It is possible to reduce the amount of operation of the generator tube, and reducing the amount of operation of the generator tube is to use less fossil fuel, it is possible to reduce the amount of greenhouse gas generated, can reduce the operating cost of the vessel.

도2에서와 같이, 선박의 선수부에 선박의 운항방향에 적합한 터널을 형성시키고 터널내부에 도1에 나타낸 수차(1)와 발전장치(2)를 설치하여 선박의 운항으로 소모되는 추진에너지를 전기에너지로 변환하는 방법과 도4에서와 같이 선박 운항시에 운전되는 냉각수펌프(4)의 출구측에 바이패스(By-Pass)배관을 설치하고, 바이패스배관에 도1에서 나타낸 수차(1)와 발전장치(2)를 설치하여 냉각수펌프(3)의 구동으로 발생되는 유체의 유동에너지를 전기에너지로 변환하는 방법As shown in Fig. 2, a tunnel suitable for the ship's operating direction is formed in the bow portion of the ship, and the propulsion energy consumed by the ship's operation is installed by installing the aberration 1 and the generator 2 shown in Fig. 1 in the tunnel. By-pass pipes are installed on the outlet side of the cooling water pump 4 which is operated at the time of vessel operation as shown in FIG. 4 and the aberration (1) shown in FIG. And a generator 2 to convert the flow energy of the fluid generated by the driving of the coolant pump 3 into electrical energy.

또한 수차(1)는 유체의 유동방향과 수차와 연결된 축의 방향이 평행한 수평축수차, 유체의 유동방향과 수차와 연결된 축의 방향이 직각을 이루는 수직축수차 그리고 유체의 유동방향과 수차와 연결된 축이 일정한 각도를 가지는 사류축수차를 사용할 수 있으며, 유체의 속도, 유량, 사용환경 등을 고려하여 최적화된 수차를 사용하여야 한다.In addition, the aberration 1 is a horizontal axis aberration in which the flow direction of the fluid and the axis connected to the aberration is parallel, a vertical axis aberration in which the direction of the fluid and the axis connected to the aberration is perpendicular to each other, and the axis connected to the flow direction and the aberration of the fluid is constant. Angled quadrilateral aberrations can be used, and optimized aberrations should be used in consideration of fluid velocity, flow rate, and use environment.
