In the embodiment, the functions of each component in the refrigeration system for methanol water reforming power generation are as follows:
the fuel tank 7 is mainly used for storing methanol water and ensuring normal fuel supply of the equipment, a liquid level detection device 71 is arranged in the fuel tank, and when the liquid level detection device 71 finds that the methanol water is insufficient, an alarm is sent to the integrated control system 4;
the hydrogen production device 1 is mainly used for converting methanol water into hydrogen through reforming reaction, and is internally provided with a set of reactors such as a reformer, a combustion chamber, a heating rod and a filter;
the buffer storage tank 6 is mainly used for storing hydrogen produced by the hydrogen production machine, the stability of the system is adjusted, when the hydrogen production device 1 is in a dormant mode, the hydrogen production efficiency is very low, at the moment, if the fuel charging pump 72 works at the maximum power, the hydrogen production device 1 does not supply gas in the future, at the moment, the buffer storage tank 6 is used for supplementing hydrogen, so that the normal operation of the pile power generation device 2 is ensured, the effect of peak clipping and deficiency supplementing is realized, and the stability of the system is ensured;
the electric pile generating set 2 mainly converts hydrogen into electric energy, and generates water and electric energy by conveying the hydrogen into the electric pile and then performing reverse reaction through a proton exchange membrane;
the integrated control system 4 mainly controls the operation of the whole system and mainly comprises a control mainboard, an air pressure detection device 61, a flow controller 8, a fuel charging pump 72, a liquid level detection device 71 and a plurality of communication lines; the hydrogen production speed of the hydrogen production device 1 is controlled by communicating the communication line with the hydrogen production device 1; the hydrogen control system is communicated with the flow controller 8 through a communication line to control the flow of hydrogen entering the pile power generation device 2 so as to control the refrigeration power; communicating with the air pressure detecting device 61 through a communication line to detect the air pressure state of the buffer tank; communicating with the fuel charge pump 72 through a communication line to pump the methanol in the fuel tank 7 into the hydrogen production apparatus 1; the liquid level detection device 71 is mainly used for detecting the residual amount of the methanol water; meanwhile, the system also comprises other functions, such as starting up, shutting down, alarming for fuel shortage, alarming for hydrogen leakage, detecting working power and other auxiliary functions;
the refrigeration load system 5 mainly comprises a compressor, a condenser, an evaporator, a four-way valve, a one-way valve, a compound valve and an electromagnetic valve, and has the functions of compressing vaporized refrigerant by using the compressor, condensing the vaporized refrigerant into liquid at the condenser, sending the refrigerant to the evaporator, evaporating the refrigerant to absorb heat, and recompressing the vaporized refrigerant by using the compressor;
the electric energy configuration device 3 mainly comprises a DC-DC energy conversion device 31 and a storage battery pack 32, and is mainly used for supplying power for the integrated control system 4 and the refrigeration load system 5, because the electric energy generated by the pile power generation device 2 is unstable, and the output range of the voltage is 75V to 100V (changed according to the air pressure of a pile and the change of the generated power), the unstable power supply can be converted into stable power supply output through the DC-DC energy conversion device 31, then one side of the output end of the DC-DC energy conversion device 31 is connected to the storage battery pack 32, and the other side of the output end of the DC-DC energy conversion device 31 supplies power for the integrated control system 4 and the refrigeration load system 5; the power supply of the refrigeration equipment cannot be met under the condition that the air pressure of the pile power generation device 2 is insufficient, and the storage battery pack 32 can supplement part of electric quantity so as to ensure the normal operation of the system; in addition, if the electric quantity output by the pile power generation device 2 is larger than the electric quantity required by the refrigeration load system 5, the redundant electric quantity is stored in the storage battery pack 32, and the function of peak clipping and vacancy supplementing as the buffer tank is achieved.
In this embodiment, the working principle is as follows:
(1) the buffer storage tank 6 can effectively ensure the smooth operation of the system, and the required working temperature of the hydrogen production device 1 is higher, so that when the equipment just starts to work, the hydrogen production device 1 is in a hot standby state, only a small amount of hydrogen can be produced, and the high power consumption mode of the equipment cannot be ensured, and at the moment, the buffer storage tank 6 needs to be supplemented with proper hydrogen to ensure the normal supply of the hydrogen; meanwhile, if the fuel charging pump 72 stops pumping water suddenly, the hydrogen production device 1 cannot stop producing hydrogen immediately (because redundant methanol mixed gas in the hydrogen production device 1 reacts with the catalyst and cannot stop), so that the produced hydrogen can be stored instead of being simply discharged into the atmosphere to cause pollution, and meanwhile, the hydrogen can be provided for the next starting device;
(2) the output of the electric energy can be reliably and stably obtained through the electric energy configuration device 3, and the equipment needs certain electric power when being started, so that the storage battery pack 32 in the electric energy configuration device 3 can supply power to the hydrogen production device 1, the integrated control system 4 and the refrigeration load system 5; when the heat engine of the hydrogen production device 1 is finished and the pressure in the buffer storage tank 6 is sufficient, the air inlet electromagnetic valve can be opened to enable the electric pile power generation device 2 to work to generate electric energy, and meanwhile, the storage battery 32 is charged, so that the electric quantity of the next start-up is sufficient; meanwhile, the whole machine can also work, and the hydrogen production amount of the hydrogen production device 1 is reduced (caused by insufficient fuel), so that the output power of the pile power generation device 2 is reduced due to insufficient hydrogen, and at the moment, the storage battery pack 32 is required to supplement insufficient electric energy to ensure the operation of the system; conversely, when the cooling load system 5 reaches the cooling temperature, the cooling load system 5 will stop working temporarily, and the power of the stack power generation device 2 cannot be reduced immediately, so that the storage battery pack 32 is required to absorb the surplus electric quantity;
because the electric energy output by the stack power generation device 2 under different conditions is also different, for example, as the output power increases, the voltage will continuously decrease (the variation range is 74V to 100V), and in addition, the hydrogen pressure will also affect the output of the stack power generation device 2, i.e., the higher the air pressure is, the higher the output voltage is, the electric energy conversion device 31 in the electric energy configuration device 3 is required to convert the electric energy to ensure the stability of the output electric energy, and the DC-DC energy conversion device 31 can not only ensure that the electric energy output voltage is maintained at our set value, but also ensure the stable output of the current under the condition that the power of the stack power generation device 2 is sufficient; if the power of the pile power generation device 2 is insufficient, the DC-DC energy conversion device 31 can only maintain the stability of voltage, the current will be reduced, and the storage battery pack 32 is needed to supplement the rest electric quantity at the moment;
(3) the whole system is controlled, scheduled and detected through the integrated control system 4;
firstly, when hydrogen leakage or methanol water leakage occurs, a detection module in the integrated control system 4 detects the leakage, gives an alarm and stops the machine;
starting a refrigeration process, firstly opening a methanol liquid inlet valve by the integrated control system 4, then opening the hydrogen production device 1 by communication control, then detecting the air pressure in the buffer storage tank 6 by the air pressure detection device 61, if the air pressure is greater than the minimum air pressure value for starting the equipment, opening the flow controller 8, otherwise, waiting for the hydrogen production device 1 to work, filling air into the buffer storage tank 6 until the air pressure in the buffer storage tank 6 is greater than the minimum air pressure value for starting the equipment (if the air pressure is insufficient, the pile power generation device 2 cannot work normally, even the service life of the pile power generation device 2 is influenced), and at the moment, supplying power to the refrigeration load system 5 by the storage battery pack 32 until the air pressure condition is met, and starting the pile power generation device 2;
and thirdly, closing the refrigerating function, namely closing the refrigerating system firstly, and then closing the electric pile. The intermediate surplus of electrical energy will be absorbed by the battery. Then, the air pressure in the buffer tank is detected by an air pressure detector, if the air pressure is larger than the minimum air pressure value of the closed equipment (mainly for the convenience of enabling the equipment to have sufficient gas available when the equipment is opened next time), the methanol water inlet pump is closed, and then the hydrogen production machine is closed. The power configuration module need not be shut down because power is also required to power the integrated control system. The power configuration module will only be turned off if the device is completely turned off.
The integrated control system 4 detects the hydrogen amount in the buffer tank through the air pressure detection device 61, if the hydrogen is insufficient, the hydrogen production power of the hydrogen production device 1 is improved, and meanwhile, the upper limit value of the flow controller 8 is set to prevent the hydrogen in the buffer tank 6 from being insufficient; similarly, if the gas in the buffer storage tank 6 is sufficient, the integrated control system 4 will also reduce the hydrogen production power of the hydrogen production apparatus 1, and release the upper limit value of the flow rate of the flow controller 8.
Preferably, because the waste gas generated by combustion of the invention is almost all water and carbon dioxide, and compared with gasoline and diesel oil, the fuel methanol water is cheaper, the fuel of the traditional equipment is inflammable, and the methanol water is very difficult to ignite, and because the refrigeration equipment mainly uses electric power at present, the refrigeration equipment is difficult to use in remote areas, or uses diesel oil and gasoline, and the transportation of the fuel is very troublesome and dangerous, but the fuel of the invention is a non-inflammable substance, the transportation is more convenient, therefore, the invention has the advantages of environmental protection, good economic effect, safe and convenient use and convenient transportation.
Therefore, the refrigeration system for methanol water reforming power generation described in the above figure is implemented, and the problems that the existing refrigeration system pollutes the environment, is high in flammability and explosion hazard, is limited by power grid infrastructure and is inconvenient to transport are solved.
In addition, the implementation of the refrigeration system for methanol water reforming power generation described in the figure has the advantages of protecting the environment, reducing noise pollution and improving power generation efficiency.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures made by using the contents of the present specification and the drawings, or applied directly or indirectly to other related technical fields, are included in the scope of the present invention.
