In the hydrogen supply method provided in the embodiment of the application, the execution main body is a controller.
The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 2 is a hydrogen supply method according to an embodiment of the present disclosure. As shown in fig. 2, the hydrogen supply method provided in the embodiment of the present application mainly includes the following steps:
and S101, in response to the received hydrogen supply request instruction, controlling a hydrogen oil module to input pre-stored hydrogen oil to a heat exchange module and controlling a dehydrogenation reaction kettle to start a heating mode.
It should be noted that the triggering conditions of the hydrogen supply request command 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 after the user performs an operation corresponding to hydrogen supply starting, the controller receives the hydrogen supplying request instruction. The preset storage value can be any feasible value. The hydrogen oil module is used for storing hydrogen oil, and contains hydrogen oil tank, oil pump and level sensor, and wherein, the oil pump is used for going out the hydrogen oil transmission in the hydrogen oil tank. Here, it should be noted that the hydrogen oil level sensor in the hydrogen oil module detects the hydrogen oil level data in the hydrogen oil tank in real time and feeds the data back to the controller. And when the controller detects that the liquid level data of the hydrogen oil is smaller than the preset threshold value, sending corresponding prompt information needing to supplement the hydrogen oil to the hydrogen oil tank to the user terminal. The dehydrogenation reaction kettle is used for heating the hydrogen oil in the dehydrogenation reaction kettle so as to heat and decompose the hydrogen oil into hydrogen and dehydrogenation oil. And, the heat exchange module includes: the heat exchanger comprises a first heat exchanger, a second heat exchanger, a third heat exchanger and a fourth heat exchanger, wherein each heat exchanger comprises a first pipeline and a second pipeline.
Specifically, after the controller receives a hydrogen supply request instruction generated based on user operation, 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 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. Therefore, when the hydrogen oil in the hydrogen oil tank is input 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 output end of the first pipeline is switched to be in an opening state by the controller, so that the hydrogen oil of the first pipeline of the first heat exchanger is input into the first pipeline of the second heat exchanger; it should be noted here that the second heat exchanger also receives high-temperature dehydrogenated oil from the dehydrogenation reactor. Therefore, when the hydrogen oil in the first pipe of the first heat exchanger is input 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; wherein, 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 detected pressure data is larger than the preset pressure value, the controller controls the safety valve to be switched to an open state so as to reduce the gas pressure in the dehydrogenation reaction kettle. It should be noted that the preset pressure value can be any feasible data, and a person skilled in the art can determine a specific value of the preset pressure value through many experiments.
And S102, responding to the condition that the temperature of the hydrogen oil in the heat exchange module is higher than a heating temperature threshold value, and controlling the input end of the dehydrogenation reaction kettle 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 value, and a person skilled in the art may determine a specific value of the heating temperature threshold through many 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 value, 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 a hydrogen output end of the dehydrogenation reactor so that hydrogen in the dehydrogenation reactor is input into the heat exchange module, and the heat exchange module cools the hydrogen.
Specifically, the dehydrogenation reactor is preset with a temperature sensor, 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 the hydrogen output end of the dehydrogenation reactor from a closed state to an open state so that high-temperature hydrogen in the dehydrogenation reactor is input into the 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 that, after the high-temperature hydrogen gas enters and exits the second pipeline of the first heat exchanger, the high-temperature hydrogen gas 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 is composed of a cold water radiator and 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, after the second pipe of the third heat exchanger receives the cold water, the cold water may cool 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 degrees celsius, the controller may further switch the dehydrogenated oil output end of the dehydrogenation reactor from a closed state to an open state, so that the high-temperature dehydrogenated oil in the dehydrogenation reactor 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 that after the high-temperature hydrogen enters and exits the second pipeline of the second heat exchanger, the high-temperature hydrogen is 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 dehydrogenated oil in 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 is composed of a cold water radiator and 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, after the second pipe of the fourth heat exchanger receives the cold water, the cold water may cool the dehydrogenated oil passing through the fourth heat exchanger due to heat transfer.
And step S104, controlling an air inlet electromagnetic valve of the fuel cell so that the fuel cell receives the cooled hydrogen.
It should be noted that the fuel cell is used for burning hydrogen and providing kinetic energy for external devices, 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 the hydrogen gas is input to the fuel cell, and the main steps are: 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 hydrogen from the first pipeline of the third heat exchanger; and the controller switches the output end of the oil-water separation module from a closed state to an 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 a closed state to an 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 and is used for secondary purification of hydrogen. And the controller controls the cold water input end of the buffer module to be switched from a closed state to an open state so as to obtain cold water from the water tank, and further, the hydrogen in the buffer is cooled again. 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 to switch 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 flowing conditions of the hydrogen oil, the hydrogen and the dehydrogenated oil are controlled by the controller, and the hydrogen oil and the hydrogen flow through the first heat exchanger are controlled, so that the cooling of the high-temperature hydrogen by the low-temperature hydrogen oil is realized; heating the low-temperature hydrogen oil by the high-temperature hydrogen; the hydrogen oil and the dehydrogenation oil after being heated are controlled to flow through the second heat exchanger, so that the low-temperature hydrogen oil is cooled to the high-temperature dehydrogenation oil, and the high-temperature dehydrogenation oil is secondarily heated to the low-temperature hydrogen oil. The secondary cooling of the hydrogen is realized by controlling the cooled hydrogen and cold water to flow through the third heat exchanger; the secondary cooling of the dehydrogenated oil is realized by controlling the cooled dehydrogenated oil and the cooled 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 hydrogen is purified. Through controlling hydrogen and cold water to flow through the buffer module, the third cooling of hydrogen is realized.
