Description

   The present invention relates to an energization system using an emergency power source that detects that power has been stopped when power is stopped due to a disaster or the like with respect to a device that is energized by a normal AC 100 V power source.

In general, various electrical devices that are energized by an AC100V power supply are used in many offices, and not only office lights but also computer devices and servers are stopped when power supply stops. Will stop the operation.
In addition, elevators, air conditioners, and various electrical equipment such as hospitals will stop operating unless they are energized at all times, for example, the entire system using the devices will be stopped, causing great damage. There are many devices.

In particular, there are things that occur due to disasters, etc. as reasons for stopping these energizations, and it is possible from experience that it will take at least several days from the occurrence of a disaster to the restoration of energization .
In these cases, an emergency power supply is generally used for backup when energization is stopped, and a battery that is often used as an emergency power supply is currently used.

However, a normal battery is energized for several hours and is used as a place to connect while it can be restored. If this time is exceeded, it will stop.
In particular, a general power outage can be used as a backup for recovery even after a few hours of power outage, but it may take about 1 to 2 days to recover in the event of a power outage caused by a disaster or the like.
Furthermore, when the power supply is stopped due to a large-scale disaster or the like, it may take two days or more as a period for the recovery.

For example, vending machines sell beverages on the street, but in the event of a disaster, they can be a very useful source of drinks for evacuees, but in the first place the power supply is stopped If it does, it will not function as any vending machine and will not be able to supply beverages.
For example, if a medical device does not operate at all times, it may become a life and death problem for a person using the device.

In these cases, a very large number of emergency power supply systems such as a power supply system using a very large battery can be used to construct a power supply system that can be energized for 2 to 3 days, but such a system is very large. In general, using such a large power supply system is not practical and cannot be used.
Recently, the use of natural energy has begun to be frequently used, and environmentally friendly energy has begun to be desired.

In particular, effective utilization of resources is desired, and attention is being paid to the utilization of resources that exist in large quantities instead of the scarce resources on the earth.
Therefore, the current magnesium air battery generates power using oxygen as a positive electrode active substance and magnesium as a negative electrode active substance and saline as an electrolytic solution. This magnesium air battery is a battery using natural energy. It is attracting attention as a power source.
For example, JP-A-2015-46312, 2012-15013, JP-A-2015-46368, and JP-A-2014-192157 exist.

JP2015-46312A 2012-15013 JP 2015-46368 JP 2014-192157 A

As described above, it is desired to provide a system that can provide an emergency power supply that can supply power for at least about three days when the power supply is stopped in a disaster or the like.
In particular, since the energized state can be maintained for this period, it is possible to provide a device that can cope with an emergency even in a medical device, for example.
In this case, it is possible to secure a power source for a predictable period until the power source is restored even in the event of a disaster, and it is desired to provide an emergency power source that can be used for at least about three days even in the case of the current disaster recovery.

In this case, if a battery is used as a general emergency power source, a very large amount of equipment is required and the cost thereof is enormous.
Therefore, salt water is placed in a cell having a positive electrode plate made of carbon having a conductivity and a catalyst, and a negative electrode plate containing at least magnesium as a main component. It is possible to energize electrical equipment for a desired time by using an emergency power source having a durability of at least 72 hours or more by using a generator using a circulating magnesium air battery constructed by circulating It is possible to provide a generator.

Therefore, when the energization is stopped, the generator using the circulation type magnesium-air battery can generate power to energize a predetermined device and can be used as an emergency power source.
In particular, a generator using such a circulating magnesium air battery can provide an emergency power source that has a durability of at least 72 hours and can be energized for at least three days.

   Therefore, the power supply system using the emergency power source is a generator using a circulation type magnesium air battery using at least a negative electrode plate made of magnesium and a positive electrode plate made of carbon having at least electrification. There are a number of cells having a negative electrode plate and a positive electrode plate, and the cells are connected to each other, and salt water is put into each cell from a tank containing salt water, and then from one cell to another cell. An emergency power source that is energized when the energized state is stopped by a generator using a circulating magnesium air battery that circulates salt water to generate electricity, a detection means that detects the deenergization, and each cell by detecting the deenergization And a means for injecting salt water into the cell, and detecting the energization stop and injecting the salt water into each cell allows the generator using the circulating magnesium air battery to start power generation and pass through. A current system by an emergency power supply to perform.

   Or you may use the electricity supply system by the emergency power supply with which the generator using the circulation type magnesium air battery is attached to electrical appliances like the invention which concerns on Claim 2.

   With this configuration, there is normally no salt water, so the ionization reaction of the negative electrode does not occur and no power is generated, but this state can be maintained for a long time. On the other hand, when there is a need for an emergency power supply due to a general energization in an emergency, that is, due to a disaster or a sudden power failure, the energization stop is detected, and salt water is injected into the cell by this detection. it can.

An ion reaction occurs by injection of salt water, and power generation is started. Therefore, it can be used as an emergency power source in an emergency.
In particular, by attaching a power source related to the electrical appliance, the electrical appliance is provided with an emergency power source in the first place, and it is possible to restore the energization even when the energization is stopped in a disaster or emergency.

The figure which shows the flow of the electricity supply system by the emergency power supply which concerns on this invention

   First, the present invention is used for an apparatus used as an emergency power source, for example, an electronic device such as an office device or a server using an AC 100V power source, an elevator as an elevator device, a communication device, or a medical device. It can also be used for various electric devices such as vending machines.

In other words, it is used for electrical appliances that are products using electricity, such as electronic devices such as office equipment and servers, elevators that are lifting equipment, communication equipment, and medical equipment.
Accordingly, in the present invention, an electric appliance refers to various products using electricity such as electronic devices such as office equipment and servers, elevators such as elevators, vending machines, communication devices, and medical devices.

   First of all, an electrical appliance including a target electric or electronic device, a device that detects an energized state or a stopped state of energization, at least a positive electrode plate made of carbon and a catalyst having at least electrification, A structure in which salt water is placed in a cell having a negative electrode plate made of magnesium and aluminum, a plurality of such cells are connected in series, and the salt water in the cell is connected to each cell to circulate the salt water. A generator using the circulating magnesium air battery, a pump for injecting salt water into each cell of the generator using the circulating magnesium air battery, and a power source for operating the pump.

   That is, firstly, stoppage of energization is detected, and in response to this detection, a pump for injecting salt water into a generator cell using a circulating magnesium air battery is operated to inject salt water into the cell. By this injection, the positive electrode plate made of carbon having at least electrification and the negative electrode plate made of at least magnesium are immersed in salt water, and power generation is started as a magnesium-air battery.

Therefore, no power is generated in the state where no salt water is contained in the cell, so that the state can be maintained as it is and the storage can be performed for a long time.
Further, when power generation is required, power generation is started by injecting salt water into the cell using a separate pump or the like.
In this case, by using a positive electrode plate made of carbon having at least electrification property and a negative electrode plate made of at least magnesium, it is possible to delay the magnesium hydroxide formation of magnesium, thereby enabling long-time power generation. Is.

FIG. 1 is a diagram showing a procedure of an emergency power supply system according to the present invention. First, a stop of energization is detected by a device that detects an energization state of a predetermined device.
Next, operation of the pump is started by such detection, and salt water is injected into the cell.
Based on this injection, power generation is started to energize a predetermined device.
Therefore, normally, since salt water is not contained, the cell having the positive electrode plate and the negative electrode plate can be stored without generating any power as it is, and can be appropriately generated in an emergency to start energization.

The generator using this circulation type magnesium air battery has many cells, these cells are connected to each other, and salt water can be circulated from one cell to another.
Accordingly, each cell containing salt water can send the salt water to another cell, and the sent cell can generate power more efficiently because salt water flows in the cell.
First, salt water may be injected from a tank, and the injection may be performed using a pump or the like.

For example, it may have a battery or the like, and start operation of a generator using a circulation type magnesium-air battery by operating a pump for injecting salt water with this battery when it is detected that energization has been stopped. .
In this case, each cell is optimally composed of a magnesium electrode as a negative electrode material, and using a negative electrode plate made of AL alloy magnesium of magnesium and aluminum, silicon, iron, and manganese.

Of course, this configuration is only an example, and it is sufficient if magnesium is mainly used as the negative electrode material. A positive electrode plate made of carbon, manganese dioxide, fluorine, toluene, a catalyst, or the like is used as a positive electrode plate for the negative electrode material.
In this case, it is also possible to use carbon having electric properties that are made into carbon fine particles.
This makes it possible to delay the formation of magnesium hydroxide by further shaping the finely divided carbon having electric properties.

Further, as a means for delaying the magnesium hydroxide formation, a positive electrode plate made of manganese dioxide, fluorine, toluene and a catalyst is used for carbon.
Of course, a positive electrode plate mainly composed of electrified carbon may be used.
In addition, the positive electrode plate may be formed by refining carbon or the like, in particular, so that the effect can be enhanced by appropriately mixing the whole.
The catalyst is an additive based on transition elements.

For example, vanadium, gold, copper, chromium, zinc, iron, cobalt, ruthenium, nickel, and molybdenum are applicable. Therefore, at least one of them is used as a catalyst.
It suffices to use at least a positive electrode plate containing carbon and a catalyst having electric properties and having manganese dioxide, fluorine, toluene, or the like as required.

Electricity is generated by circulating salt water in a cell having such a positive electrode plate and a negative electrode plate. For example, salt water is put in a total of 12 cells, and these cells are connected by a pipe for circulating salt water. Then, salt water may be circulated.
In this way, if one unit is configured as one circulation system, and a unit in which a plurality of units or a plurality of units are connected to form one generator as a whole, long-time power generation is possible. It will be a thing.

Therefore, by configuring as described above, it is possible to provide an emergency power source capable of generating power for at least 72 hours.
In addition, regarding the energization generated in this way, the inverter converts the direct current into alternating current and energizes the equipment.
In addition, such an emergency power supply may be used as a power supply for portable devices.

   Since the emergency power source according to this configuration is a very useful invention that can be used even in the event of an emergency, that is, for a long time in the event of a disaster, such as portable devices that are often used in emergencies. It is good also as what can be used also as a power supply regarding such a portable device.

   It should be noted that the electric appliance has a generator using such a circulation type magnesium air battery in the first place, a detection means for detecting the stop of energization, and a means for injecting salt water into each cell by detecting the stop of the energization. Thus, it is possible to provide such an electric appliance, and it is possible to maintain a state in which no power is generated since salt water is not contained in the cell at normal times.

Furthermore, in the case of constant use in such a state, a power failure or the like occurs in a disaster or emergency, and the energization is stopped.
Therefore, these electric appliances do not operate at all and fall into a state where their functions cannot be performed at all.
Especially in the event of a disaster, the use of electrical appliances is particularly expected, but this is not possible.

Therefore, it is possible to detect this energization stop for such an electrical appliance, and when this energization stop is detected, a generator using a circulating magnesium air battery is first prepared by injecting salt water into each cell. Power generation can be started.
This can use an energization system with an emergency power source for energization, and can provide an electrical appliance very usefully.
