Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a power generator,
In particular, the present invention is effective when applied to a case where power is supplied to an underwater vehicle such as an underwater robot or a submarine, or an underwater base.

[0002]

2. Description of the Related Art The following conditions must be satisfied in a power generating apparatus for generating power using an underwater vehicle such as an underwater robot or a submarine, or an underwater base. (1) Since there is no air, an oxygen generator is required. (2) It is necessary to make a closed cycle so as not to be affected by the depth pressure. (3) No generation of exhaust gas and the like.

[0003] For this reason, it has been considered to apply a fuel cell in which electric power is obtained by electrochemically reacting hydrogen and oxygen to a power generator used in water or the like.
As shown in FIG. 4, a fuel cell-applied power generation device is configured such that the oxygen 1 in an oxygen cylinder 11 is adjusted to an operating pressure by an oxygen pressure control device 12 while the temperature is adjusted by an oxygen temperature control device 13, and then the fuel cell 31 While the hydrogen 2 in the hydrogen cylinder 15 is temperature-adjusted by the hydrogen temperature controller 17 while being adjusted to the operating pressure by the hydrogen pressure controller 16, the fuel cell 10
The oxygen 1 and the hydrogen 2 are electrochemically reacted with each other to generate electric power and water 3 by being supplied to the inside 1, and the electricity is stored in the secondary battery 102 and used for the load 103 of various electric systems, The water 3 is stored in the water tank 104.

[0004]

However, the above-described power generator has the following problems.

[0005] (1) Since oxygen 1 and hydrogen 2 are stored in gas, if a sufficient power generation capacity is to be obtained, the space required for storing these raw materials 1 and 2 becomes very large. There was a limit to the improvement of Therefore, although it is conceivable to improve the storage density of these raw materials 1 and 2 by using liquefied oxygen 1 and hydrogen 2, liquid hydrogen has a large spontaneous evaporation amount and is difficult to store for a long time. For this reason, it is practically difficult to apply liquid hydrogen to actual equipment.

(2) In order to improve the efficiency of the electrochemical reaction, oxygen 1 and hydrogen 2 are heated to a predetermined temperature (generally around 100 ° C.) by the respective temperature control devices 13 and 17 and then supplied to the fuel cell 101. There is a need. The energy required for this heating is several percent of the power generation energy, and there is a great waste of energy.

(3) The water 3 generated by the reaction is transferred to a water tank 104
Since it is stored as it is in a space, there is a waste in space. If the water 3 is discharged to the outside when applied to an underwater vehicle, the buoyancy will be increased by the discharged weight, and the buoyancy balance will be lost or the center of gravity will be shifted, This is because attitude control becomes difficult.

In view of the above, an object of the present invention is to provide a power generation device which is compact, has high energy efficiency and can be used for a long time.

By controlling the temperature and pressure of these gases 1 and 2 so as to supply them to the fuel cell 101, power is generated by the fuel cell 101 (from the control limit, the oxygen 1 and hydrogen 2 Although the supply amount may be temporarily unbalanced, the consumption of oxygen 1 and hydrogen 2 in the fuel cell 101 depends on the equivalence ratio, so that oxygen 1 and hydrogen 2 accumulate unreacted. Is not.) Since an equivalent reaction is performed in the fuel cell 101, the reaction product is only water 3 (see the following chemical formula).

[Formula 1] H ₂ + 1 / 2O ₂ → H ₂ O

The oxygen gas generator 110 includes a storage container 11
Liquid oxygen 1 is stored in the heat exchanger 112, and the oxygen 1 is stored in the heat exchanger 112.
Is vaporized and supplied into the system. Oxygen gas generator 1
10 and the heat exchangers 112 and 12 of the oxygen pressure regulator 120
The heat required for the second heat medium 6 uses the heat of reaction between the water 3 and the metal fuel 4 in the holding container 151 of the hydrogen gas generator 150 by the heat exchanger 152, so that the output of the fuel cell 101 is Heating power, which requires several% of the above, becomes unnecessary.

On the other hand, the hydrogen gas generator 150 holds the metal fuel 4 in a molten state in the holding container 151 and injects the water 3 from the injection nozzle 155 into the holding container 151, so that the water 3 and the metal fuel 4 and react with each other to generate hydrogen 2 and supply it into the system. Since the water 3 and the metal fuel 4 cause an exothermic reaction, the internal temperature of the holding container 151 increases (locally reaches 1000 ° C. or higher). Therefore, by collecting the reaction heat in the heat exchanger 152, the temperature rise in the holding vessel 151 is suppressed, and the oxygen gas generator 110 and the oxygen pressure controller 12
0 is used as a heat source of the heat medium 6 of the heat exchangers 112 and 122.

The oxygen 1 and hydrogen 2 supplied through the respective temperature control devices 130 and 170 are electrochemically reacted in the fuel cell 101 to generate electric power and water 3. The amount of water 3 generated in the fuel cell 101 corresponds to the consumption of hydrogen 2 required for the output of the fuel cell 101 at that time. Therefore, the same amount of water 3 as the water 3 generated in the fuel cell 101 is fed into the holding container 151 of the hydrogen gas generator 150 to supply the metal fuel 4.
By reacting with water, the required amount of hydrogen 2 can be generated, and at the same time, there is no need to store extra water 3.

That is, since the amount of water 3 generated from the fuel cell 101 is equal to the amount of water 3 containing hydrogen 2 required for the equivalent reaction, hydrogen 2 is separated from this water 3. This is the basic idea of the present invention.

When aluminum is applied to the metal fuel 4, in the holding container 151 of the hydrogen gas generator 150,
The reaction shown in the following chemical formula occurs.

[Formula 2] 2 / 3Al + H ₂ O → 1 / 3Al ₂ O ₃ + H ₂

That is, the present invention relates to the oxygen gas generator 11
It can be considered as a system that generates electric power in the process where oxygen 1 from 0 moves to the hydrogen gas generator 150.
Therefore, the phenomenon that the amount of water 3 in the system increases does not occur.

The oxygen 1 and hydrogen 2 generated from the generators 110 and 150 are supplied to the pressure regulators 120 and 160, respectively.
Then, via the respective temperature control devices 130 and 170, the conditions required for use in the fuel cell 101 are adjusted. Since the oxygen 1 and the hydrogen 2 supplied to the fuel cell 101 are consumed in an equivalent amount according to the output of the fuel cell 101, they may be supplied at a pressure corresponding to the output (the temperature is substantially constant regardless of the output). Is.). Therefore, each control device 140, 1
According to 80, the amounts of generated oxygen 1 and hydrogen 2 are controlled so that oxygen 1 and hydrogen 2 can be supplied at a predetermined pressure.

According to the power generator of this embodiment, the following effects can be obtained.

(1) The water 3 generated by the fuel cell 101 is
Since the water 3 is reused in the hydrogen gas generator 150, the stored water 3 does not increase.

(2) The metal fuel 4 for generating hydrogen 2
Because it is solid at room temperature, it is excellent for long-term storage,
At a high temperature, hydrogen 2 easily reacts with water 3 to generate hydrogen 2, so that the generation density of hydrogen 2 is extremely high. For this reason, it is possible to achieve weight reduction and space saving as compared with a system that generates hydrogen 2 by gasification from a liquefied state, and high-efficiency power generation and long-time power generation are possible.

(3) Since the generation amount of hydrogen 2 and the supply amount of water 3 are in a proportional relationship, the generation amount of hydrogen 2 can be easily adjusted by controlling the supply amount of water 3.

(4) Since the liquid oxygen 1 is vaporized by utilizing the heat of reaction between the metal fuel 4 and water, the power consumption in the system can be reduced and the power generation efficiency can be improved.

(5) Since aluminum and liquid oxygen are inexpensive, running costs such as operating costs can be reduced.

As shown in FIG. 3, the hot pipe 217 is connected to the feed pump 213 at one end with its axial center directed in the horizontal direction, and is open at the other end to form a plurality of hot pipes at the upper side.

24).

<Operation / Effect> The power generation device of the present embodiment is significantly different from the power generation device of the above-described embodiment in that oxygen generator 5 is heated and decomposed by oxygen gas generator 210 to generate oxygen 1. ing.

Specifically, the oxygen generating agent 5 heated to the melting point by a heater (not shown) or the like in the holding container 211 is supplied by the feed pump 213 to the pipe body 217 of the hot pipe 217.
a from one end of the pipe main body 217, and is heated and decomposed by the starting heater 217c to generate oxygen 1 and generate the pipe body 217.
The liquid is sent out from the through hole 217aa and the other end side of a, and is sent out through the filter 216 while being decelerated by being detoured by the splash prevention plate 218.

The reason why the through-hole 217aa is formed in the pipe main body 217a of the hot pipe 217 is that, in the process of thermally decomposing the oxygen generating agent 5, the generated oxygen 1 causes the oxygen generating agent 5 which is being decomposed to pass through the other end. This is to prevent the material from being pushed out from the outside (that is, a "release hole").

When lithium perchlorate is used as the oxygen generating agent 5, the following reaction occurs in the hot pipe 217.

[Formula 3] LiClO ₄ → LiCl + 2O ₂

Lithium perchlorate has a decomposition temperature of 440 ° C.
For this reason, when heated above this temperature, it decomposes to generate oxygen 1 and generates heat up to 800 ° C. or more. Therefore, when the decomposition reaction starts to some extent in the hot pipe 217, the temperature above the decomposition temperature can be maintained without supplying power to the starting heater 217c. Also,
The pipe body 217a of the hot pipe 217 is
7b, the inside of the pipe main body 217a can be easily maintained at a temperature equal to or higher than the decomposition temperature, and the power consumption of the starting heater 217c can be reduced.

a (lithium chloride in the case of using lithium perchlorate as the oxygen generating agent 5) flows out of the other end of the pipe body 217a of the hot pipe 217 in a liquid state (melting point: 608 ° C.) and drops into the holding container 211. I do. At this time, since the melting temperature of the oxygen generating agent 5 is sufficiently different from the decomposition temperature, the oxygen generating agent 5 in the holding container 211 does not cause a decomposition reaction.

In the above-described embodiment, the oxygen 1 generated by the oxygen gas generator 110 is
In the present embodiment, since the temperature of the oxygen 1 generated from the oxygen gas generator 210 reaches several hundred degrees Celsius, the heat exchanger 222 of the oxygen pressure regulator 220 is used.

According to the power generator of this embodiment, the same effects as those of the above-described embodiment can be obtained, and the following effects can be obtained.

(1) Oxygen generator 5 for generating oxygen 1
Since is a solid at room temperature, it is excellent in long-term storage and has an extremely high oxygen 1 generation density. For this reason, it is possible to reduce the weight and space in comparison with a system that generates oxygen 1 by gasification from a liquefied state, is excellent in volumetric efficiency, and enables high-efficiency power generation and long-time power generation.

(2) Since the amount of generated oxygen 1 is proportional to the amount of thermally decomposed oxygen generating agent 5, the amount of oxygen generating agent 5 supplied to hot pipe 217 is controlled (feed pump 21).

a to form the pipe body 2 of the oxygen generating agent 5.

(5) Most of the oxygen generating agent 5 is water-soluble, and the holding container 211 of the oxygen gas generator 210 can be reused only by washing with water, which is excellent in cost. .

And heating means for heating and evaporating the liquid oxygen inside the system, (1) power consumption in the system can be reduced, and power generation efficiency can be improved. (2) Low-cost liquid oxygen can be used, and running costs such as operating costs can be reduced.

Further, the oxygen gas generating means includes a holding means for holding an oxygen generating agent that generates an oxygen gas by being thermally decomposed, and a heating means for heating the oxygen generating agent. A compact power generator with high energy efficiency and long-term use can be provided.

Further, the heating means of the oxygen gas generating means is provided in the holding means with a feed pump for feeding the oxygen generating agent in the holding means, and has an axial center along the horizontal direction. A pipe main body having the feed pump connected to one end thereof and opened at the other end thereof, and having a plurality of through holes formed on an upper side thereof, and a starting heater for heating the pipe main body. Therefore, (1) the amount of generated oxygen and the amount of thermal decomposition of the oxygen generating agent have a proportional relationship, and the amount of oxygen generated by controlling the supply amount of the oxygen generating agent to the pipe body (adjusting the feed pump) is controlled. The amount of generation can be easily adjusted. (2) The contact time of the oxygen generating agent with the pipe main body can be increased, and the efficiency of thermal decomposition of the oxygen generating agent supplied to the pipe main body can be increased.

Further, since the heating means of the oxygen gas generating means is provided with a heat insulating material surrounding the pipe body, the heat generated by the decomposition reaction of the oxygen generating agent can be kept warm, and a short stop state can be achieved. Then, oxygen can be generated without restarting the starting heater.

Further, since the metal fuel is made of any one of aluminum, magnesium, lithium, lithium hydride, sodium and sodium hydride or a combination thereof, it is excellent in long-term storage because it is solid at normal temperature. At the same time, when the temperature is increased, the hydrogen easily reacts with water to generate hydrogen, so that the generation density of hydrogen is extremely high. For this reason, it is possible to reduce the weight and space compared to a system that generates hydrogen by gasification from a liquefied state,
High-efficiency power generation and long-term power generation are possible.

Further, since the oxygen generating agent is a perchlorate or an inorganic peroxide, since it is a solid at normal temperature, it is excellent in long-term storage and has a very high oxygen generation density. For this reason, it is possible to achieve weight reduction and space saving compared to a system that generates oxygen by gasification from a liquefied state, is excellent in volumetric efficiency, and enables high-efficiency power generation and long-time power generation.

Further, since the power generation device is a fuel cell, the above effects can be more effectively exhibited.
