Description

Technical Field

[0001] The present invention relates to the technical field of metal-air batteries, and in particular to an emergency protection device for a water-electric-heat integrated metal-air fuel cell. Background Art

[0002] With the progress and development of human society, in order to avoid the excessive consumption of traditional fossil energy and carbon dioxide greenhouse gas emissions, the upgrading of the energy industry and the use of clean energy have attracted increasing attention. Especially in recent years, with the rapid development of technologies such as new energy vehicles, smart microgrids and 5G mobile communications, human social development has become more and more dependent on electric energy, and human social activities have increasingly higher requirements for power supply and economy. However, existing fuel generators and various chemical power sources (such as lead-acid batteries, lithium-ion batteries, hydrogen fuel cells, etc.) are difficult to fully meet people's diverse needs for power safety, economy and long battery life. In particular, in the military and civilian pain points such as emergency power supply environmental pollution, major disaster water, electricity and heat emergency support, short battery life of power batteries, wartime power supply security and strategic alternative energy, the traditional energy system is difficult to provide a suitable power supply solution.

[0003] Metal-air battery, also known as metal-air fuel cell or metal fuel cell, is a power generation / energy storage device that directly converts chemical energy of light metals such as magnesium and aluminum into electrical energy. It has the advantages of high specific energy density, low cost, high safety, low thermal radiation, low noise, long storage time, long discharge life, wide temperature range, abundant resources and green and pollution-free. In particular, the specific energy density is much higher than other traditional batteries, among which the theoretical energy density of aluminum can reach 8140 watt-hours / kilogram, which is dozens of times that of current commercial lithium-ion batteries. Therefore, it is called "green energy for the 21st century".

[0004] Given the above advantages of metal-air batteries, they are very suitable for solving the pain points of certain military and civilian scenarios as emergency and backup power sources.

DETAILED DESCRIPTION

[0036] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention.

[0037] Example

[0038] like Figure 1-4 As shown, a water-electric-heat integrated metal-air fuel cell emergency protection device comprises:

[0039] The shell 1 includes an openable upper cover 11; the openable upper cover 11 facilitates the metal-air battery stack module 4 to be taken out from the shell 1 and placed on the shell 1. The upper cover 11 can be partially opened or completely opened.

[0040] The cavity 2 is arranged in the housing 1 and is located at a corresponding position below the upper cover 11; the cavity 2 is formed with the housing 1 through a partition 201. The cavity 2 can be used to store the metal air battery stack module 4, and can also be used as an electrolyte box to store electrolyte, thereby reducing the volume of the overall device and increasing the convenience of carrying.

[0041] The water supply unit 3 includes a control component, a filter device and a water cooling pipe 32. The water cooling pipe 32 is laid at the bottom of the cavity 2 and contacts the electrolyte. The control component is electrically connected to the metal air battery stack module 4. The water supply unit 3 is arranged in the shell 1, and a water inlet and a water outlet are arranged on the shell 1. The water source of the water supply unit 3 can be municipal domestic water, or a natural water source such as river water or rain water. The water cooling pipe 32 of the water supply unit 3 can quickly dissipate the heat of the fuel cell electrolyte through the design of the electrolyte tank. In addition, the water flow after absorbing the heat has its own temperature increased, which provides better comfort and convenience for domestic water in bad weather outdoors, and can be used without heating by another heat source. Therefore, on the one hand, the problem of too fast heating when the fuel-air battery generates electricity is solved, and on the other hand, the waste heat generated by the fuel-air battery can be collected and utilized again, killing two birds with one stone, and truly achieving the effect of water, electricity and heat integration.

[0042] The metal-air battery stack module 4 can be movably arranged in the cavity 2 as a whole. The metal-air battery stack module 4 includes a battery stack 41, a buffer tank 42 and a control unit 44. At least part of the opening of the buffer tank is connected to the battery stack 41. A liquid inlet pipe 21 and a liquid outlet pipe 22 are connected between the buffer tank 42 and the cavity 2. The control unit 44 is electrically connected to the battery stack 41. The battery stack 41 is composed of at least two or more metal-air battery cells, and the metal-air battery cells are mainly composed of a cathode plate and an anode plate. The battery stack 41 is placed above the buffer tank 42, so that the circulating inlet and outlet liquids in the battery stack 41 are collected and redistributed by the buffer tank 42, so that each cell can operate smoothly. The control unit 44 is integrated on the stack to manage and control the operation of the entire metal-air battery stack module 4. The liquid inlet pipe 21 and the liquid outlet pipe 22 can be directly connected by hoses, and the metal-air battery stack module 4 does not need to be disassembled when taking it out and putting it into the cavity 2; the liquid inlet pipe 21 and the liquid outlet pipe 22 can also be connected by hard pipes, and the liquid inlet pipe 21 and the liquid outlet pipe 22 need to be disassembled and installed when taking the metal-air battery stack module 4 out and putting it into the cavity 2.

[0043] Wherein, when the device is in a non-working state, the metal-air battery stack module 4 is placed in the cavity 2, and when the device is in a normal working state, the metal-air battery stack module 4 is taken out of the cavity 2 and placed above the upper cover 11, and the electrolyte is injected into the cavity 2 for the battery stack 41 to generate electricity and output electrical energy. The electrolyte is a strong alkaline solution or a neutral salt solution, preferably, the strong alkaline solution is a KOH electrolyte or a NaOH electrolyte, and the neutral salt solution is a NaCl salt solution.

[0044] In one embodiment, the inlet end of the liquid inlet pipe 21 is connected to an infusion pump 23, the infusion pump 23 is arranged in the cavity 2, and the infusion pump 23 is electrically connected to the metal air battery stack module 4. The liquid inlet pipe 21, the liquid outlet pipe 22 and the infusion pump 23 constitute an electrolyte filling circulation unit, which provides electrolyte supplement for the metal air battery stack module 4. At the same time, through the circulation unit, the heat in the battery stack 41 is output through the high-temperature electrolyte, and then heat is exchanged with the water cooling pipe 32, and the low-temperature electrolyte after the heat utilization is completed is recycled into the battery stack 41 for its power generation.

[0045] In one embodiment, the control component includes at least one solenoid valve (not shown), and the solenoid valve is connected to at least one of the water inlet end or the water outlet end of the water supply unit 3. Preferably, the control component also includes a water supply pump (not shown), and the water supply pump is connected to the water inlet end of the water supply unit 3.

[0046] In one embodiment, the filtering device is a primary filtering device 31 , and the primary filtering device 31 is disposed at the water inlet end of the water cooling pipe 32 .

[0047] In one embodiment, the filtering device is composed of a primary filtering device 31 and at least one level of precision filtering device 33 , and the precision filtering device 33 is arranged at the water inlet end or the water outlet end of the water cooling pipe 32 .

[0048] The primary filter device 31 and the precision filter device 33 are arranged in the housing 1. After the ordinary water source is filtered by the primary filter device 31, it is purified by two-stage precision filtration to produce domestic water. Further, if it is purified by three-stage precision filtration, it can produce water suitable for drinking.

[0049] In one embodiment, the metal-air battery stack module 4 further includes at least one radiator 43, which is close to the cathode side of the battery stack 41. The radiator 43 is an air-cooled heat dissipation system, which is attached to the battery stack 41 to fully dissipate the temperature of the battery stack 41.

[0050] In one embodiment, the control unit 44 is a single chip integrated module. The control unit 44 is used to provide power guarantee for the infusion pump 23, water supply pump, solenoid valve, radiator 43 and other electrical devices in different output modes such as constant voltage, constant current or constant power. At the same time, the control unit 44 is used to control the start and stop actions of the infusion pump 23, water supply pump, solenoid valve, radiator 43 and other electrical devices.

[0051] In one embodiment, the device further includes an interface for an external power source. The interface is connected to the external power source, which may be a portable low-power power battery, such as a lithium battery. The external power source activates the infusion pump 23, thereby causing the electrolyte to enter the battery stack 41 to generate electricity.

[0052] The working process of the emergency protection device of the present invention is as follows:

[0053] When the metal-air fuel cell is used, first, the metal-air battery stack module 4 is taken out from the shell 1 and placed above the upper cover 11 of the shell 1; secondly, the electrolyte is prepared in the cavity 2, and the electrolyte filling circulation pipeline is connected. The external power battery is used as the starting power supply to start the infusion pump 23, so that the metal-air battery stack module 4 starts to work and generate electricity. The electricity generated by the battery provides power to the water supply unit 3 to drive the water supply unit 3 to work. The sewage is filtered by the primary filter device 31 and enters the water cooling pipe 32. It is then purified by the secondary or tertiary precision filter device 33 to produce domestic water or direct drinking water. Since the water is heated by the high-temperature electrolyte, the produced water is warm water, which is convenient for daily use. The electricity generated by the battery also provides power for the infusion pump 23 and the radiator 43, so that the radiator 43 works and can continue to work after the external starting power supply is removed.

[0054] When the metal-air fuel cell stops being used, the stop button on the control unit 44 of the metal-air battery stack module 4 is turned off, and the battery stops generating electricity.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
