A typical hydrogen energy power generation device is a hydrogen energy power generation vehicle, and a fire safety system suitable for the hydrogen energy power generation vehicle is described below as an example of the fire safety system.
The hydrogen energy power generation vehicle is a novel emergency power generation vehicle, is popular among people due to the fact that the energy conversion efficiency is high, the generated noise is low, no environmental pollutants are generated in the power generation process, and can be widely applied to places such as major political activities, hospitals and engineering emergency rescue.
The existing hydrogen energy power generation vehicle generally comprises a hydrogen fuel cell power generation system, a voltage transformation system, an energy storage system, a chassis vehicle and a compartment. The hydrogen fuel cell power generation system generates electric energy by consuming hydrogen fuel, the energy storage system can store the electric energy generated by the hydrogen fuel cell power generation system, the voltage conversion system converts the electric energy generated by the hydrogen fuel cell power generation system and the voltage provided by the power supply circuit of the hydrogen energy power generation vehicle so that the electric energy can be used by the hydrogen energy power generation vehicle and electric equipment or stored by the energy storage system, and the chassis vehicle enables the hydrogen energy power generation vehicle to move.
Because the power generation process of the hydrogen fuel cell power generation system is the combustion process of the hydrogen fuel, the combustion process of the hydrogen fuel can release more heat, the voltage conversion system, the energy storage system, the chassis car and other electrical structures can also emit heat in the working process, in order to keep the normal working environment temperature in the carriage, the normal work of the hydrogen energy power generation car is prevented from being influenced by the overhigh environmental temperature in the carriage, and a carriage ventilation system for exchanging gas between the gas environment in the carriage and the atmospheric environment and maintaining the working environment temperature in the carriage is generally arranged on the carriage of the hydrogen energy power generation car.
In one example, carriage ventilation system sets up exhaust fan, the shutter and sets up the air conditioner in the carriage including the intercommunication, and exhaust fan, shutter and air conditioner are electrically controlled device, and the cooperation through exhaust fan and shutter can realize the gaseous interaction of gaseous environment and atmospheric environment in the carriage to make the interior airflow of carriage take away the interior heat of carriage, the air conditioner can reduce the interior operational environment temperature of carriage, further maintains comparatively normal operating temperature in the carriage.
The above-mentioned hydrogen fuel power generation vehicle is an example for illustrating the above-mentioned fire safety system, and the hydrogen energy power generation vehicle is a mature technology in the prior art, and its representation form is not limited by the above description, it should be understood that the above-mentioned fire safety system can be applied to any hydrogen fuel power generation vehicle.
The fire safety system comprises a fire detection subsystem 1, a fire processing subsystem 2 and a fire management subsystem 3. The fire detection subsystem 1 is used for detecting whether a fire exists in a carriage of the hydrogen energy power generation vehicle or not, the fire processing subsystem 2 is used for processing the fire existing in the carriage, and the fire management subsystem 3 controls the action of the fire processing subsystem 2 and the action of the hydrogen energy power generation vehicle according to the detection result of the fire detection subsystem 1 so as to inhibit the spread of the fire in the carriage and process the fire in the carriage.
The fire detection subsystem 1 includes one or more fire detectors disposed in the vehicle compartment to detect the presence of a fire in the vehicle compartment. The fire detector is a device for detecting and finding a fire, which determines whether a fire is occurring according to a change in environmental parameters before and after the fire is occurring. The fire detector can be set as a smoke detector, a temperature-sensitive detector, a flame-sensitive detector or a combustible gas detector in the prior art, and it should be noted that the fire detector can be applied to the fire detection subsystem 1 and can detect the fire, and the fire detector in the prior art is numerous and cannot be exhaustive.
In practical use, in order to comprehensively and quickly detect the fire, the fire detection subsystem 1 generally detects the fire in the carriage by combining a plurality of fire detectors, and the fire detectors are generally arranged at positions corresponding to the application principle of the fire detectors to detect the fire, and if the smoke detectors sense whether smoke exists, the fire detectors judge whether the fire exists, so the fire detectors are generally arranged at the positions where the smoke is easy to diffuse, such as the top in the carriage; the temperature-sensing detector judges whether the fire exists by sensing whether the ambient temperature in the carriage has the risk of fire, so the temperature-sensing detector is generally arranged beside a part which is easy to generate the fire, such as an electrical structure in the carriage; a flame detector, that is, a flame detector, which judges whether a fire occurs by detecting visible or invisible light radiation that is generated when a fire occurs in a vehicle compartment or not, and is generally disposed beside a portion where a fire easily occurs, such as an electrical structure in a vehicle compartment; the combustible gas detector judges whether enough combustible gas for supporting fire occurs in the carriage or not by detecting the concentration of the combustible gas in the carriage, and the combustible gas is generally dispersed hydrogen fuel in the leaked carriage.
The fire detection subsystem 1 also responds to the fire output alarm signal in the carriage, namely the fire detection subsystem 1 comprises a fire detector, and further comprises an alarm device which outputs the alarm signal, the alarm device can be a warning lamp, a buzzer, a light emitting diode and the like, and can prompt the operator of the hydrogen fuel power generation vehicle to generate the fire in the carriage through sound or light.
The fire treatment subsystem 2 is the fire extinguishing system that handles the condition of a fire in the carriage promptly, and it can set up to arbitrary fire extinguishing system among the prior art, including but not limited to automatic sprinkler system, fire water supply system, gaseous fire extinguishing system, fire hydrant system, fire extinguisher, only need set up in the carriage and can handle the condition of a fire in the carriage promptly to put out the action can. Of course, the structure of the hydrogen fuel power generation vehicle itself cannot be damaged by considering the fire extinguishing principle when the fire processing subsystem 2 is actually arranged, if the electric structure in the carriage can be damaged by adopting water spraying for fire extinguishing, and if the dry powder fire extinguisher is adopted, the carriage can be cleaned after being extinguished, and is inconvenient to repair quickly and put into use again, so the fire processing subsystem 2 is preferably a gas fire extinguishing system in the example.
The fire-fighting management subsystem 3 is a control center of the whole fire-fighting safety system, is connected with the fire detection subsystem 1 and the fire processing subsystem 2, and is connected with a compartment ventilation system of the hydrogen energy power generation vehicle through the ventilation control subsystem 4, the ventilation control subsystem 4 comprises an exhaust fan controller, an air conditioner controller and a shutter controller which are respectively used for controlling the opening and closing of the exhaust fan, the air conditioner and the shutter of the compartment ventilation system, and the exhaust fan controller, the air conditioner controller and the shutter controller are connected with the fire-fighting management subsystem 3. The fire management subsystem 3 processes the fire in the carriage by controlling the carriage ventilation system and the fire processing subsystem 2 according to the detection result of the fire detection subsystem 1, so that the spread of the fire is inhibited, the speed of extinguishing the fire is increased, and the possibility of igniting and exploding the hydrogen fuel is reduced.
When a hydrogen energy source electric power generation vehicle is actually installed, it is common to keep the hydrogen fuel cell electric power generation system as far as possible from other electric structures in the vehicle cabin for safety reasons. However, the hydrogen fuel is hydrogen gas, the density of the hydrogen fuel is only 7% of that of air, the hydrogen fuel has high buoyancy in the air and high diffusivity and volatility, once the hydrogen fuel leaks, the hydrogen gas can be rapidly diffused into a carriage, and the diffusion speed is increased according to the increase of the airflow speed in the carriage; if the electric structure in the carriage produces sparks due to line faults or other reasons, the sparks can be ignited and generate fire when meeting hydrogen, the airflow flowing in the carriage can provide combustible hydrogen for the fire and combustion improver oxygen for the fire, and once the hydrogen reaches 4% -75.6% of the volume content in the carriage, explosion can be generated when the hydrogen is ignited. Therefore, when a fire occurs in the carriage, the gas flow in the carriage is inhibited, so that the fire spreading can be effectively inhibited, and even the fire is automatically extinguished because of no enough combustible substances and combustion-supporting substances.
The fire control management subsystem 3 carries out the action of putting out a fire promptly based on above-mentioned principle promptly and handling promptly, the action that the fire control management subsystem 3 control carriage ventilation system and the action of putting out a fire of the cooperation work of fire processing subsystem 2 is carried out in response to receiving above-mentioned alarm signal action, when the fire control management subsystem 3 received above-mentioned alarm signal, control carriage ventilation system to close earlier promptly, the air discharge fan, the air conditioner, the shutter all closes, with the gaseous flow in suppression carriage of the closed effect through carriage itself, then control the action of fire processing subsystem 2 and put out a fire, in order to realize high-efficient, quick fire extinguishing, reduce the fire and handle the degree of difficulty, reduce the time that the fire processing process consumed, reduce the possibility that hydrogen fuel was lighted and is exploded.
Furthermore, the fire management subsystem 3 is also connected with a hydrogen fuel cell power generation system and an energy storage system of the hydrogen energy power generation vehicle through a power generation system controller and an energy storage system controller respectively, and the fire management subsystem 3 further comprises a main incoming line switch controller and a main outgoing line switch controller which control the on and off of a main incoming line switch and a main outgoing line switch of the hydrogen energy power generation vehicle respectively.
The fire control management system responds to the received alarm signal and controls the closing of the hydrogen fuel cell power generation system and the energy storage system through the power generation system controller and the energy storage system controller, the closing of the hydrogen fuel cell power generation system can reduce the possibility of further leakage of hydrogen fuel, the possibility of continuous increase of combustible substances, namely the hydrogen fuel, in the carriage is reduced, the spreading of fire is restrained, and the possibility of explosion is reduced, the closing of the energy storage system can stop the power supply of the energy storage system to an electric structure in the carriage, so that the possibility of power supply, repeated electric spark generation, fire growth or extinguishment of the fire existing in a circuit part of the electric structure is reduced. So as to further reduce the difficulty of fire treatment, improve the speed of fire treatment and reduce the possibility of hydrogen fuel explosion.
The general incoming line switch hydrogen energy power generation car is connected with the power supply circuit, the general outgoing line switch hydrogen energy power generation car is connected with the electric equipment, the electric connection state of the power supply circuit and the hydrogen energy power generation car and the electric connection state of the hydrogen energy power generation car and the electric equipment can be changed through the general incoming line switch controller and the general outgoing line switch controller, and whether the power supply circuit supplies power to the hydrogen energy power generation car or not and whether the hydrogen energy power generation car supplies power to the electric equipment or not are controlled. The electrical switch modules in the example are preferably the main inlet switch and the main outlet switch of the hydrogen energy power generation vehicle. The fire control management subsystem 3 is in response to receiving alarm signal control hydrogen energy power generation car's total incoming line switch and total outgoing line switch action with disconnection hydrogen energy power generation car and consumer, the electricity between the supply circuit is connected, when the electrical switch module moves, the electrical switch module cuts off hydrogen energy power generation car and supply circuit, the electricity of consumer is connected, can make the whole state that does not have the external power supply of hydrogen fuel power generation car, it has the electric energy supply to reduce electric structure circuit part, the repeated electric spark that produces, help the condition of a fire or make the possibility of the condition of a fire that puts out reburning. So as to further reduce the difficulty of fire treatment, improve the speed of fire treatment and reduce the possibility of hydrogen fuel explosion.
Considering the actual use situation, preferably, the fire management subsystem 3 controls the car ventilation system to be closed when receiving the alarm signal, then controls the fire processing subsystem 2 to be started and the hydrogen fuel power generation system and the energy storage system to be closed at the same time, and finally controls the electrical switch module to be disconnected. Namely, the gas flow in the carriage is inhibited to inhibit the fire from spreading, then the fire is treated, and finally the risk of the reignition and further expansion of the fire is reduced.
Particularly, the hydrogen fuel power generation system and the energy storage system are closed firstly, then the power supply circuit is disconnected with the electrical connection of the hydrogen energy power generation car, the electric arc generated by the large current generated by the disconnection of the electrical switch module can be avoided, the possibility that the hydrogen fuel cell power generation system and the energy storage system discharge to the electrical structure of the hydrogen energy power generation car after the power supply circuit stops supplying power to the hydrogen energy power generation car is simultaneously prevented, the electrical structure of the hydrogen energy power generation car is not supplied with electric energy, and the possibility that the fault circuit has electric energy supply, encourages the fire or enables the extinguished fire to be reburned is further reduced.
The fire management subsystem 3 further comprises a manual control key, and an operator can input a starting signal and/or a set time length signal to the fire management subsystem 3 through the manual control key. When receiving the starting signal, the fire management subsystem 3 also performs a series of fire processing actions after receiving the alarm signal without repeated description; the set time length signal enables the fire management subsystem 3 to carry out the series of fire handling actions after the time delay set time length of the starting signal/alarm signal is received.
The manual control key is convenient for an operator to actively start a series of fire processing actions of the fire safety system on one hand, the process of artificially controlling the fire processing is more flexible and convenient, the operator can find the fire in the carriage before the fire detector actively processes the fire, and the speed of processing the fire is further improved; on the other hand, because the compartment is required to be relatively closed in the fire handling action, if an operator is in the compartment, the operator is trapped in the compartment, personal safety is caused to the operator, and through setting the time delay, enough time for evacuating the compartment is reserved for the operator in the compartment when receiving the alarm signal or when keying in the starting signal, so that the personal safety of the operator is favorably ensured.
In addition, the fire fighting system may include a fire prevention operation when only the fire detection subsystem 1, the fire management subsystem 3, and the ventilation control subsystem 4 are present.
Specifically, the fire detection subsystem 1 comprises one or more fire detectors, the one or more fire detectors are also connected with the fire management subsystem 3, the fire detectors comprise combustible gas detectors, when the combustible gas detector detects that the environmental concentration of the combustible gas in the carriage reaches the condition of fire, namely when the concentration of the hydrogen fuel in the carriage reaches the combustion concentration environment, the fire-fighting management subsystem 3 controls the ventilation control subsystem 4 to work so as to control the ventilation system of the carriage to be opened, the carriage is ventilated, the hydrogen fuel concentration in the carriage is reduced, on one hand, the probability that the combustible with lower concentration meets the electric spark is reduced, on the other hand, the combustible with lower concentration can not be ignited or is not easy to ignite even if meeting the electric spark, thereby reducing the possibility of fire in the carrying box and reducing the possibility of explosion caused by the ignition of the leaked hydrogen fuel.
Of course, when actually deploying the fire safety system, the fire safety system is generally required to have both the function of preventing the occurrence of a fire and the function of handling the existing fire, and the system structure of the fire safety system having the function of handling the fire includes the fire safety system having the function of preventing the occurrence of a fire, that is, when actually deploying the fire safety system, the system structure is generally directly deployed as a complete subsystem structure of the fire safety system having the function of handling the fire.
In the fire safety system of the complete subsystem structure, the fire detection subsystem 1 has the detection capability of the concentration environment of the combustible materials in the carriage and the detection capability of whether the fire exists in the carriage, and the fire detection subsystem 1 is set to send a preprocessing signal to the fire management subsystem 3 when the fire detection subsystem 1 detects that the concentration environment of the combustible materials in the carriage reaches the condition of fire occurrence but the fire does not exist in the carriage, so that the fire management subsystem 3 can perform the process of preventing the fire occurrence.
The implementation principle of the embodiment is as follows:
under the automatic control state, when the fire detection subsystem 1 detects that no fire occurs in the compartment of the hydrogen fuel power generation vehicle but the hydrogen fuel concentration reaches the condition of supporting the occurrence of the fire, the fire management subsystem 3 controls the compartment ventilation system to be opened to ventilate the compartment, so that the hydrogen fuel concentration in the compartment is reduced, and the risks of the occurrence of the fire and the explosion are reduced; when the fire detection subsystem 1 detects a fire in the carriage of the hydrogen energy power generation vehicle, the fire management subsystem 3 controls the carriage ventilation system to be closed firstly after the time delay is set, and then controls the fire processing subsystem 2 to be started and the hydrogen fuel power generation system and the energy storage system to be closed simultaneously, and finally controls the electrical switch module to be disconnected. Namely, the gas flow in the carriage is inhibited to inhibit the fire from spreading, then the fire is treated, and finally the risk of the reignition and further expansion of the fire is reduced. Is beneficial to improving the fire processing speed and reducing the possibility of hydrogen fuel explosion.
Under the manual control state, an operator actively discovers the fire in the carriage, inputs a starting signal into the fire management subsystem 3 through a manual control key, and after the fire management subsystem 3 sets time delay, the fire management subsystem controls the ventilation system of the carriage to be closed, and then controls the fire processing subsystem 2 to be started, the hydrogen fuel power generation system and the energy storage system to be closed, and finally controls the switch module of the electric appliance to be disconnected. Namely, the gas flow in the carriage is inhibited to inhibit the fire from spreading, then the fire is treated, and finally the risk of the reignition and further expansion of the fire is reduced. Is beneficial to improving the fire processing speed and reducing the possibility of hydrogen fuel explosion.
Of course, the automatic control state and the manual control state of the fire management subsystem 3 can be switched, and the switching mode is the prior art and is not specifically disclosed.
It can be understood that, in addition to the system composition of the fire safety system itself, the above disclosure also describes a specific arrangement mode of applying the fire safety system to a hydrogen energy power generation vehicle, so that those skilled in the art can form not only the fire safety system itself but also a hydrogen energy power generation vehicle with the fire safety system according to the above disclosure.
