The hydrogen supply method provided in the embodiment of the application has the implementation main body of a controller.
The following describes the technical scheme provided by the embodiment of the application in detail through the attached drawings.
Fig. 2 is a schematic diagram of a hydrogen supplying method according to an embodiment of the present application. As shown in fig. 2, the hydrogen supply method provided by the embodiment of the application mainly includes the following steps:
step S101, in response to receiving a hydrogen supply request instruction, controlling the hydrogen oil module to input the pre-stored hydrogen oil into the heat exchange module and controlling the dehydrogenation reaction kettle to start a heating mode.
The triggering conditions of the hydrogen supply request instruction are as follows: when the controller detects that the storage amount of the hydrogen in the fuel cell is lower than a preset storage value, a hydrogen supplementing request instruction is sent to a user, and when the user performs an operation corresponding to starting hydrogen supply, the controller receives the hydrogen supply request instruction. The preset storage value can be any feasible value. The hydrogen oil module is used for storing hydrogen oil and comprises a hydrogen oil tank, an oil pump and a liquid level sensor, wherein the oil pump is used for transmitting the hydrogen oil in the hydrogen oil tank. Here, the hydrogen oil level sensor in the hydrogen oil module detects hydrogen oil level data in the hydrogen oil tank in real time and feeds the data back to the controller. When the controller detects that the hydrogen oil level data is smaller than a preset threshold value, corresponding prompt information for supplementing hydrogen oil to the hydrogen oil tank is sent to the user terminal. The dehydrogenation reaction kettle is used for heating the hydrogen oil in the dehydrogenation reaction kettle so as to thermally decompose the hydrogen oil into hydrogen and dehydrogenation oil. And, the heat exchange module includes: the first heat exchanger, the second heat exchanger, the third heat exchanger and the fourth heat exchanger, and each heat exchanger comprises a first pipeline and a second pipeline.
Specifically, after the controller receives a hydrogen supply request instruction generated based on the operation of a user, a start instruction is sent to the oil pump, and meanwhile, the input end of the first pipeline of the first heat exchanger is switched to be in an open state, so that the oil pump inputs hydrogen oil in the hydrogen oil tank to the input end of the first pipeline of the first heat exchanger of the heat exchange module. It should be noted that, as shown in fig. 1, the first heat exchanger also receives high-temperature hydrogen from the dehydrogenation reactor. Thus, when the hydrogen oil in the hydrogen oil tank is inputted to the first pipe of the first heat exchanger of the heat exchange module, the hydrogen oil will be heated due to heat transfer. Then, the controller switches the output end of the first pipeline to be in an open state so as to input hydrogen oil of the first pipeline of the first heat exchanger into the first pipeline of the second heat exchanger; the second heat exchanger also receives high-temperature dehydrogenation oil from the dehydrogenation reactor. Thus, when the hydrogen oil of the first pipe of the first heat exchanger is inputted to the first pipe of the second heat exchanger, the hydrogen oil will be heated again due to heat transfer.
In addition, the controller also switches the operation state of the dehydrogenation reaction kettle to a heating mode, and at the moment, the dehydrogenation reaction kettle starts to heat the hydrogen oil in the kettle. The dehydrogenation reaction kettle comprises a pressure sensor and a safety valve; the pressure sensor is used for detecting the gas pressure in the dehydrogenation reaction kettle. The controller receives pressure data in the dehydrogenation reaction kettle uploaded by the pressure sensor in real time; when the pressure data is detected to be larger than a preset pressure value, the controller controls the safety valve to be switched into an open state so as to reduce the gas pressure in the dehydrogenation reaction kettle. It should be noted that the preset pressure value may be any feasible data, and a person skilled in the art may determine a specific value of the preset pressure value through multiple experiments.
In step S102, in response to the temperature of the hydrogen oil in the heat exchange module being higher than the heating temperature threshold, the input end of the dehydrogenation reaction kettle is controlled so that the dehydrogenation reaction kettle receives the hydrogen oil from the heat exchange module.
It should be noted that the heating temperature threshold may be any feasible number, and those skilled in the art may determine the specific value of the heating temperature threshold through multiple experiments.
Specifically, a temperature sensor is preset in the first pipeline of the second heat exchanger, and the temperature sensor sends the temperature of the hydrogen oil in the first pipeline of the second heat exchanger to the controller in real time. When the controller detects that the temperature is greater than the heating temperature threshold, the controller switches the input end of the dehydrogenation reaction kettle from a closed state to an open state so that the dehydrogenation reaction kettle receives the heated hydrogen oil transmitted from the output end of the first pipeline of the second heat exchanger.
Step S103, controlling the hydrogen output end of the dehydrogenation reaction kettle so that the hydrogen in the dehydrogenation reaction kettle is input into the heat exchange module, and cooling the hydrogen by the heat exchange module.
Specifically, a temperature sensor is preset in the dehydrogenation reaction kettle, the temperature sensor transmits detected temperature data to the controller in real time, and when the controller detects that the temperature data is greater than 200 ℃, the controller switches a hydrogen output end of the dehydrogenation reaction kettle from a closed state to an open state so that high-temperature hydrogen in the dehydrogenation reaction kettle is input into a second pipeline of the first heat exchanger. It should be noted that, the first heat exchanger also receives the hydrogen oil from the hydrogen oil module, so, after the high-temperature hydrogen enters and exits the second pipeline of the first heat exchanger, the high-temperature hydrogen is cooled by the hydrogen oil of the hydrogen oil module due to heat transfer.
Then, the controller switches the output end of the second pipeline of the first heat exchanger from the closed state to the open state so that the hydrogen of the second pipeline of the first heat exchanger is input into the first pipeline of the third heat exchanger. It should be noted that the controller may control the cold water pump to transfer the water in the water tank to the heat dissipation module. The heat dissipation module consists of a cold water radiator and is used for cooling input water and transmitting the cold water to the input end of the second pipeline of the third heat exchanger through the output end of the heat dissipation module. It should be noted that, when the second pipe of the third heat exchanger receives cold water, the cold water cools the hydrogen passing through the third heat exchanger due to heat transfer.
In addition, it should be noted that when the controller detects that the temperature data is greater than 200 ℃, the controller also switches the dehydrogenation oil output end of the dehydrogenation reaction kettle from the closed state to the open state, so that the high-temperature dehydrogenation oil in the dehydrogenation reaction kettle is input into the second pipeline of the second heat exchanger. It should be noted that, the second heat exchanger also receives the hydrogen oil from the first heat exchanger, so, after the high-temperature hydrogen enters and exits to the second pipeline of the second heat exchanger, the high-temperature hydrogen will be cooled by the hydrogen oil from the first heat exchanger due to heat transfer.
Then, the controller switches the output end of the second pipeline of the second heat exchanger from the closed state to the open state so that the dehydrogenation oil of the second pipeline of the second heat exchanger is input into the first pipeline of the fourth heat exchanger. It should be noted that the controller may control the cold water pump to transfer the water in the water tank to the heat dissipation module. The heat dissipation module consists of a cold water radiator and is used for cooling input water and transmitting the cold water to the input end of the second pipeline of the fourth heat exchanger through the output end of the heat dissipation module. It should be noted that, when the second pipe of the fourth heat exchanger receives cold water, the cold water cools the dehydrogenated oil passing through the fourth heat exchanger due to heat transfer.
Step S104, controlling an air inlet electromagnetic valve of the fuel cell so that the fuel cell receives the cooled hydrogen.
The fuel cell is used for combusting hydrogen and providing kinetic energy for external equipment, and the air inlet solenoid valve is used for controlling the hydrogen to enter the fuel cell.
Specifically, the controller may further purify the hydrogen gas before inputting the hydrogen gas into the fuel cell, mainly comprising the steps of: the controller switches the output end of the first pipeline of the third heat exchanger from a closed state to an open state so as to transmit the hydrogen in the first pipeline of the third heat exchanger to the oil-water separation module. The oil-water separation module is formed by connecting a plurality of oil-water separators in series and is used for purifying hydrogen; and the number of the oil-water separators is at least two. The controller controls the input end of the oil-water separation module to be switched from a closed state to an open state and is used for receiving the hydrogen from the first pipeline of the third heat exchanger; and the controller switches the output end of the oil-water separation module from the closed state to the open state so as to transmit the hydrogen purified by the oil-water separation module to the buffer module. The controller controls the input end of the buffer module to be switched from the closed state to the open state so as to receive the hydrogen purified by the oil-water separation module; it should be noted that the buffer module is composed of a plurality of buffers connected in series for performing secondary purification on the hydrogen. And the controller controls the cold water input end of the buffer module to be switched from the closed state to the open state so as to acquire cold water from the water tank, thereby realizing the re-cooling of the hydrogen in the buffer. The controller switches the output end of the control buffer module from a closed state to an open state, and controls the air inlet electromagnetic valve of the fuel cell from the closed state to the open state, so as to transmit the hydrogen purified again by the buffer module to the fuel cell.
According to the method provided by the embodiment of the application, the flow conditions of hydrogen oil, hydrogen and dehydrogenation oil are controlled by the controller, and the low-temperature hydrogen oil is used for cooling high-temperature hydrogen by controlling the hydrogen oil and hydrogen to flow through the first heat exchanger; and heating the low-temperature hydrogen oil by the high-temperature hydrogen; by controlling the heated hydrogen oil and the dehydrogenation oil to flow through the second heat exchanger, the temperature of the low-temperature hydrogen oil to the high-temperature dehydrogenation oil is reduced, and the secondary heating of the high-temperature dehydrogenation oil to the low-temperature hydrogen oil is realized. The hydrogen and cold water after cooling are controlled to flow through the third heat exchanger, so that the hydrogen is cooled for the second time; the secondary cooling of the dehydrogenated oil is realized by controlling the cooled dehydrogenated oil and cold water to flow through the fourth heat exchanger. The hydrogen after the secondary cooling is controlled to flow through the oil-water separation module and the buffer module, so that the purification of the hydrogen is realized. The third cooling of the hydrogen is realized by controlling the hydrogen and cold water to flow through the buffer module.
