In order to make the above and other objects, features and advantages of the present invention more obvious and understandable, the preferred embodiments of the present invention are described below in detail with the accompanying drawings: Please refer to Figure 1. It is an embodiment of the marine power plant of the present invention, which includes a wind pipe 1, a seawater desalination assembly 2, an electrolytic cell 3, a wind power generator 4, and a fuel cell 5. The seawater desalination assembly 2 is respectively connected to the wind The tube 1 and the electrolytic cell 3, the wind power generator 4 is located in the wind pipe 1 and is electrically connected to the electrolytic cell 3, and the fuel cell 5 is connected to the electrolytic cell 3.

Please refer to Figures 1 and 2 together. The air duct 1 includes an air inlet 1a and an air outlet 1b. The air duct 1 is a tube with a non-equal inner diameter and is based on the difference in the inner diameter of the air duct 1. , Can be divided into an air inlet section 11, a low pressure section 12 and a buffer section 13 from the air inlet 1a to the air outlet 1b in order; due to the influence of the change of the inner diameter of the air pipe 1, the airflow passes through the air pipe 1 The flow rate will be changed in different sections, so that the airflow has different temperature and pressure in different sections.

In detail, the low pressure section 12 is reduced in diameter relative to the air inlet section 11 and the buffer section 13, that is, the inner diameter of the low pressure section 12 is smaller than the inner diameters of the air inlet section 11 and the buffer section 13, so There is a relative pressure difference between the low-pressure section 12 and the air inlet section 11, and between the low-pressure section 12 and the buffer section 13, and the speed of air flowing through the low-pressure section 12 is faster than that when flowing through the air inlet section 11 and The buffer section 13 is fast, so that the airflow in the low pressure section 12 maintains a low temperature and low pressure state.

Please refer to Figures 1 to 3, the seawater desalination assembly 2 includes a flashing part 21 and a condensing part 22. The flashing part 21 is connected to the outside by a seawater inlet pipe T1 to facilitate the introduction of a seawater for distillation; The steaming member 21 can be connected to a seawater drain pipe to discharge the residual high-concentration seawater after distillation, which should be easily understood by those with ordinary knowledge in the art, and will not be repeated here. The flashing element 21 is connected to the condensing element 22 by a vapor tube T2, and the condensing element 22 is surrounding the low pressure section 12, so that a low pressure environment can be formed inside the flashing element 21 and the condensing element 22, After the seawater is introduced into the flashing member 21, the boiling point of the seawater decreases due to the pressure drop, so that the seawater can instantly evaporate to produce a water vapor with low salinity, and the water vapor continues to enter the condensation along the steam tube T2 Piece 22 and condense.

The condensing element 22 is arranged around the low-pressure section 12. Since the low-pressure section 12 is in a low temperature state, a low-temperature environment is formed inside the condensing element 22. The water vapor enters the condensing element 22 and condenses into a fresh water. The seawater desalination assembly 2 may further have a plurality of heat conducting elements 23, each of the heat conducting elements 23 is located in the condensing element 22, and preferably penetrates the low pressure section 12 of the air duct 1, whereby the condensing element 22 and the The gas in the air duct 1 can exchange heat through the plurality of heat-conducting members 23 to maintain the low temperature of the condensing member 22 and help the water vapor to condense.

Please refer to Figures 1 and 2 again. The electrolytic cell 3 is connected to the condensing element 22 by a fresh water pipe T3. The fresh water condensed in the condensing element 22 can be led to the electrolytic cell 3 and used in the electrolysis. The tank 3 is electrolyzed to form hydrogen and oxygen.

The wind power generating element 4 is located in the wind pipe 1, and the wind power generating element 4 may be A fan driven by the airflow, when the airflow passes through the wind pipe 1, can also drive the wind power generator 4 to run and generate electricity; the wind power generator 4 is preferably located in the buffer section 13 of the wind pipe 1 to avoid the wind The power generating element 4 slows down the flow rate of the airflow passing through the low pressure section 12. The wind power generator 4 is electrically connected to the electrolytic cell 3 to provide power for electrolysis of the fresh water in the electrolytic cell 3.

The fuel cell 5 is connected to the electrolytic cell 3 with a first hydrogen tube T4 and an oxygen tube T5, respectively, so as to utilize the hydrogen and oxygen generated by the electrolysis of the fresh water to generate electricity. For example, but without limitation, the fuel cell 5 can be a zinc-air fuel cell. Oxygen oxidizes the metallic zinc in the zinc-air fuel cell. The metallic zinc can generate electricity while forming zinc oxide. On the other hand, hydrogen can reduce oxidation. Zinc restores zinc oxide to the form of metallic zinc so that it can react with oxygen again, thereby eliminating the need to repeatedly replace the reacted zinc oxide with metallic zinc, which can reduce power generation costs and save ship storage space.

The marine power plant of this embodiment may further include a pressurizing component 6 and a heat generating element 7. The pressurizing element 6 is used to pressurize an air into a high-pressure air, and the heat generating element 7 can be used for the high-pressure air. The energy contained is converted into heat. The pressurizing assembly 6 may include a rotating pressurizing member 61, an air duct T6 connecting the rotating pressurizing member 61 and the outside, and an exhaust pipe T7 connecting the rotating pressurizing member 61 and the low pressure section of the air duct 1 12. Since the low pressure section 12 is in a low pressure state, a pressure difference is formed between the inside of the rotary pressurizing part 61 and the low pressure section 12, which drives the air to flow from the outside into the rotary pressurizing part 61, and then further flows to The low pressure section 12.

Please refer to Figures 4a and 4b, the rotating pressing member 61 is formed with a housing 611, the rotating pressing member 61 further includes a rotating shaft 612 and a rotating body 613, the rotating shaft 612 is preferably fixed to the shell At the center of the body 611, the rotating body 613 is located in the housing 611 and relatively rotates around the rotating shaft 612. It is worth noting that the rotating body 613 can divide the interior of the housing 611 into several spaces, and the rotating body 613 preferably rotates eccentrically with respect to the rotating shaft 612, so that when the rotating body 613 rotates, the volume of each space can be Changes; in detail, as shown in Figure 4a, the swivel 613 and the A compression space S may be formed between the casings 611. Then, as shown in Figure 4b, when the rotor 613 is pushed by the air, the volume of the compression space S is reduced due to the eccentric rotation of the rotor 613, thereby The air in the compression space S is compressed.

Please refer to Figures 5a and 5b again. The pressurizing assembly 6 may further include at least one swing pressurizing member 62. The swing pressurizing member 62 has a cylinder 621 and a piston 622, and the piston 622 is located in the cylinder. The body 621 fits the inner wall of the cylinder body 621 to divide the space in the cylinder body 621 into a first compression chamber 621a and a second compression chamber 621b; This causes the piston 622 to reciprocate in the cylinder 621, causing the volumes of the first compression chamber 621a and the second compression chamber 621b to continuously change, and the total volume of the first compression chamber 621a and the second compression chamber 621b is equal to That is, when the piston 622 moves to reduce the volume of the first compression chamber 621a, it will also cause the volume of the second compression chamber 621b to increase, and vice versa.

The swing pressurizing member 62 also has an air storage tank 623, and each of the compression chambers 621a and 621b has an intake valve and an exhaust valve respectively. The two intake valves can communicate with the outside, and the two exhaust valves are connected The gas storage tank 623; the two intake valves and the two exhaust valves are all one-way valves, so that gas can only enter the cylinder 621 from the outside, or can only enter the gas storage tank 623 from the cylinder 621 . As shown in Figure 5b, when the piston 622 tilts to one side due to the swing of the ship, it will compress the air in the second compression chamber 621b and force the air in the second compression chamber 621b to flow to the air storage tank 623 ; At the same time, the air pressure in the first compression chamber 621a decreases because of the increase in the volume of the first compression chamber 621a. At this time, the outside air pressure is higher than the first compression chamber 621a, so that the air from the outside to the first compression chamber 621a Flowing in the compression chamber 621a, in this way, air can be continuously replenished and compressed.

The ship power plant of this embodiment may include one or several swing pressurizing members 62. When the ship power plant includes several swing pressurizing members 62, the multiple swing pressurizing members may be shown in Figure 5a. 62 are connected in series to connect the inlet valve of the swing pressure member 62 installed later The air storage groove 623 of the swing pressurizing member 62 installed first, and the air storage groove 623 of the swing pressurizing member 62 installed last is connected to the heat generating member 7, thereby allowing air to pass through the Several oscillating pressurizing members 62 are gradually pressurized to an appropriate pressure and then sent to the heat generating member 7.

Please refer to Figures 1 and 2, the heat generating element 7 is connected to the rotating pressurizing element 61 and the swing pressurizing element 62 by a high-pressure air tube T8 respectively, so as to introduce the high pressure air into the heat generating element 7 Work, so that the internal energy originally existing in the high-pressure air is released in the form of heat energy. The fresh water pipe T3 connecting the condensing element 22 and the electrolytic cell 3 can pass through the heat generating element 7, so that the fresh water flowing to the electrolytic cell 3 can be heated, and the relatively high-temperature fresh water has a higher efficiency during electrolysis , Can increase the production rate of oxygen and hydrogen.

The marine power plant of this embodiment may further include a carbon dioxide capture component 8 for capturing carbon dioxide in the air. The carbon dioxide capture assembly 8 may include a carbon dioxide absorbing member 81 to communicate with the air pipe 1. An alkaline solution may flow through the air pipe 1 through the carbon dioxide absorbing member 81 and contact the airflow in the air pipe 1, resulting in Carbon dioxide is dissolved in the lye; the carbon dioxide absorbing member 81 is preferably connected to the buffer section 13 of the air pipe 1, so that the airflow with a slower flow velocity contacts the lye, and the contact time between the airflow and the lye is prolonged to increase the carbon dioxide The amount of dissolution. The carbon dioxide absorber 81 may be a lye pipe passing through the air pipe 1, and the portion of the lye pipe in the air pipe 1 may be provided with a plurality of vent holes 811, and each vent hole 811 is only used in the air pipe 1. The airflow flows into the lye tube and prevents the lye from leaking from the lye tube. For example, but without limitation, the vent holes 811 can be pores with a gas-permeable membrane, thereby achieving Breathable and prevent liquid leakage.

The carbon dioxide capture assembly 8 further includes a lye tank 82 connected to the carbon dioxide absorbing member 81 for the lye with carbon dioxide to release carbon dioxide in the lye tank 82 to collect carbon dioxide. Specifically, the lye tank 82 is connected to the carbon dioxide absorber 81 through an inlet pipe T9 and a discharge pipe T10 respectively, and the lye flows from the lye tank 82 to the two through the inlet pipe T9. The carbon oxide absorber 81, after absorbing carbon dioxide in the carbon dioxide absorber 81, flows back to the lye tank 82 along the drain pipe T10, and discharges the carbon dioxide from the lye tank 82, so that it can be reused The lye.

The drain pipe T10 preferably passes through the heat generating member 7 to heat the lye with carbon dioxide in the drain pipe T10, reduce the solubility of carbon dioxide in the lye, and help the carbon dioxide to be discharged; or, the lye tank A lye heater 821 can be additionally provided in 82, and the lye heater 821 can be electrically connected to the wind power generating element 4 to heat the lye by electric power, which can be understood by those with ordinary knowledge in the art, so it will not be repeated .

The carbon dioxide captured by the carbon dioxide capture assembly 8 can be sent to a fuel generating tank 9 through a carbon dioxide pipe T11, and the fuel generating tank 9 is connected to the first hydrogen pipe T4 by a second hydrogen pipe T12. Accordingly, the carbon dioxide And part of the hydrogen generated by the electrolysis of the fresh water can enter the fuel generation tank 9 and react in the fuel generation tank 9 to obtain a fuel containing components such as methanol or dimethyl ether, which can be used as a backup fuel for ships.

The marine power plant of this embodiment may further include a spare power generating element E, and the electric energy generated by the spare power generating element E can be used for components that require electricity such as the electrolytic cell 3 or the lye heater 821. The standby power generating element E may be a solar power generating element E1, a power generating mechanism E2, or both. The solar power generating element E1 may be a conventional solar panel and other equipment that converts solar energy into electrical energy; the power generating mechanism E2 may It is a hybrid gas power generation mechanism that uses the shock wave energy of a metal gas at high pressure and high temperature to ionize the metal gas to generate electric current. A similar mechanism has been disclosed in the ROC Publication No. 201326552 "Hybrid Gas Power Generation Device" patent In the case, the operation principle of the power generation mechanism E2 will not be repeated here.

It is worth noting that the power generation equipment E2 may have a heat exchanger E21, and the carbon dioxide tube T11 may pass through the heat exchanger E21, thereby transferring the excess heat of the carbon dioxide captured by the carbon dioxide capture assembly 8 to the power generation equipment E2 The metal gas can not only add By heating the metal gas, the temperature of carbon dioxide can be maintained appropriately to prevent the carbon dioxide and hydrogen from reacting too quickly and causing danger.

According to the foregoing structure, the ship power plant of this embodiment can be installed on a ship, wherein the wind pipe 1 preferably extends vertically upward from the ship to prevent the ship body from blocking the airflow into the wind pipe 1, and The air inlet 1a of the air duct 1 preferably faces the windward side of the ship, so that the airflow can enter the air duct 1 more easily. When the ship starts to travel, the airflow can enter the air duct 1 from the air inlet 1a and blow from the air inlet 1a to the air outlet 1b. When the airflow passes through the low pressure section 12 of the air pipe 1, it will be affected by the flow velocity. The low-pressure section 12 is in a low-temperature and low-pressure state, and a low-pressure environment is formed inside the seawater desalination assembly 2 connected to the low-pressure section 12, so that a seawater introduced into the desalination assembly 2 can be flashed and evaporated. Condensed into a fresh water, the fresh water continues to enter the electrolytic cell 3 along the fresh water pipe T3 and is electrolyzed into hydrogen and oxygen in the electrolytic cell 3.

When the airflow passes through the buffer section 13, the wind power generating element 4 located in the buffer section 13 can be pushed, thereby generating electricity for electrolyzing the fresh water. In addition, the rotary pressurizing member 61 and the swing pressurizing member 62 use air flow and ship shaking motion as power to pressurize the air, and the heat generating member 7 uses the pressurized high-pressure air to generate heat and heat The fresh water to be electrolyzed further improves the efficiency of the fresh water being electrolyzed.

The oxygen formed by the electrolysis of the fresh water reaches the fuel cell 5 through the oxygen tube T5, and is used to oxidize a battery material in the fuel cell 5 to generate electricity. The generated electricity is used to drive a propeller of the ship (Figure (Not shown), and the hydrogen formed by electrolysis reaches the fuel cell 5 through the first hydrogen pipe T4, and is used to reduce the oxidized battery material to reuse the battery material; thereby, the fuel cell 5 can The use of wind power or sea water obtained during navigation to generate electricity does not need to rely on ports or rely on supply ships to supply fuel, which greatly reduces the navigation time and energy costs for navigation.

On the other hand, when the airflow passes through the air duct 1, it can touch the buffer section 13 The carbon dioxide absorbing member 81 is provided to dissolve carbon dioxide into an lye in the carbon dioxide absorbing member 81, thereby capturing carbon dioxide in the airflow. The captured carbon dioxide and the hydrogen generated by the electrolysis of the fresh water can be reacted in the fuel generating tank 9 to obtain the fuel containing methanol or dimethyl ether as a backup power source for the ship.

In summary, in the marine power plant of the present invention, the wind pipe and the wind power generator can provide energy to desalinate a sea water into a fresh water, and electrolyze the fresh water into hydrogen and oxygen. The fuel cell uses the hydrogen and Oxygen undergoes oxidation-reduction reactions, so that the battery materials in the fuel cell can be reused, reducing the number of times that the ship replenishes fuel or battery materials while sailing, thereby reducing the cost and time of sailing.
