Description

ENERGY SAVING SHIP WITH POWER GENERATION SYSTEM USING ORC}

The present invention relates to an energy-saving vessel equipped with a power generation device using a temperature difference, and more particularly, to install an organic Rankine cycle device, which is to produce power by heat exchange with the cooling water and sea water of the ship heat engine. The present invention relates to an energy-saving vessel equipped with a power generator using a temperature difference.

In general, a ship converts thermal energy generated by burning fossil fuel in a main engine into rotational kinetic energy of a propeller-mounted propulsion shaft.

For example, a container vessel of about 8,000 TEU class consumes 15 tons of fuel for propulsion in the main engine, and the heat generated by burning such a large amount of fuel oil is considerable.

Part of this heat energy is converted into kinetic energy and used for propulsion of ships, but the part not converted into kinetic energy is usually discharged to the outside of the engine by operating a cooling system using fresh water and sea water. It prevents overheating.

Therefore, since the cooling system is always operated during ship navigation, in the case of medium or large ships, a large amount of hot water and cold water circulate inside the hull.

Looking at the circulation process of the cooling system of the ship main pipe 11, as shown in Figure 1, in this cooling system to absorb the heat of the main pipe 11 by using the cold and fresh water flowing through the cold and clean water line (14). By absorbing heat and discharging warmed water, the temperature of which is high, is discharged to the heat exchanger 12 through the warm water water line 13, and heat-exchanged with the seawater introduced through the cold sea water line 15 in the heat exchanger 12. The engine 11 is cooled.

At this time, the warm sea water absorbed heat from the warm water and the temperature is high is discharged to the sea through the warm sea water line (16).

In addition to the main engines used for the propulsion of ships, auxiliary engines for producing electric power supplied to various electric devices used in ships, such as various pumps in the hull, various facilities within the residential area, cranes used for loading and unloading cargo, etc. In the case of a facility such as a boiler, a cooling system having the same circulation process as the main engine 11 as shown in FIG. 1 is operated to prevent overheating of the mechanical device due to the use of a large amount of fuel oil.

However, in such a circulation process, a large amount of heat is not reused, and there is a problem in that it is discarded at sea.

In recent years, even when the global GHG regulation is not free, ships can save energy by using the energy resources available in the hull and reduce the use of fossil fuels to reduce greenhouse gas emissions. Development is urgently required.

In order to solve the problems as described above and to meet the requirements of the present situation, the present invention is easily vaporized at the same temperature as the cooling water of the main engine, auxiliary engine and boiler drain cooler, and the temperature such as room temperature or sea water temperature Equipped with an organic Rankine cycle device that generates power by repeating evaporation and liquefaction by repeatedly circulating the evaporator and condenser using a working fluid that is easily liquefied in the ship. The purpose is to provide an energy-saving vessel equipped with a power generator using a temperature difference that can be recycled to save fuel oil and reduce greenhouse gas emissions.

In particular, the present invention comprises a power generator using a temperature difference with the cooling water of the main engine, the auxiliary engine and the boiler drain cooler as the high heat source and the seawater as the low heat source as the high heat source, The purpose is to provide an energy-saving vessel equipped with a power generation device using a temperature difference that can maximize energy recycling efficiency.

Through the problem solving means as described above, the present invention is to continuously maintain the turbine by repeating the vaporization and liquefaction of the working fluid in the evaporator and condenser using the high temperature cooling water and the low temperature seawater to drive the overheating of the vessel heat engine. By driving the power generated there is an advantage that can be recycled resources released from the system of the existing ship.

Especially in the case of medium and large ships, the flow rate of hot and cold water circulated for the operation of the cooling system is considerable, and the cooling system must be operated at all times. The gas emission reduction effect also has the advantage that can be expected.

As shown in FIG. 2, the organic rankine cycle device 20 absorbs heat from an external heat source in the evaporator 21 (static pressure heating process), and when the working fluid is vaporized, the pressure in the cycle device 20 is increased. Due to the rapid increase, the increased pressure causes the turbine 22 installed in the cycle to rotate, whereby power is produced by converting rotational kinetic energy of the rotating turbine 22 into electrical energy (thermal insulation expansion). process).

Then, the turbine 22 drives and passes the gas back into the condenser 23 and loses heat through heat exchange with an external heat source (static pressure dissipation process) and condenses (insulation compression process). The pump 24 is recycled to the evaporator 21 to continuously produce power.

The organic Rankine cycle device 20 is characterized in that the higher the temperature of the external heat source (high heat source) on the high temperature side and the lower the temperature of the external heat source (low heat source) on the low temperature side, the higher the efficiency.

The present invention produces the power by installing the organic Rankine cycle apparatus 20 as shown in Figure 2 in the cooling system of various heat engines 11, such as the main engine, auxiliary engine, boiler of the ship as shown in FIG. I did it.

As the seawater is discharged to the outboard-> cold seawater line (15)-> heat exchanger (12)-> warm seawater line (16)-> outboard, fresh water and seawater The heat exchanger 12 is to heat exchange.

In the present invention, as described above, the organic Rankine cycle apparatus 20 is provided to generate electric power while the working fluid circulates through the evaporator 21, the turbine 22, the condenser 23, and the pump 24. Here, the evaporator 21 of the organic Rankine cycle device 20 is configured to be heat-exchanged with the warm and clean water line 13, the condenser 23 of the organic Rankine cycle 15 and the cold sea water line 15.
