Description

Technical Field

[0001] The present application relates to the field of operation management, and in particular to a safety management system and method for a vehicle-mounted methanol hydrogen generator. Background Art

[0002] With the urgent global demand for clean energy and the continuous development of hydrogen energy technology, methanol, as a hydrogen source with broad prospects, has become a hot topic in research. Methanol hydrogen production technology can not only achieve large-scale production of hydrogen, but also has the advantages of a wide range of raw materials, renewable and environmentally friendly.

[0003] Existing methanol engines usually use fossil fuels such as gasoline, diesel or natural gas as ignition fuel to solve the problem of methanol engine cold start difficulty. This method requires the vehicle to be filled with two fuels (methanol and others) at the same time, and to be equipped with two sets of fuel supply systems, fuel storage systems, etc., which increases the vehicle's own weight and cost, and the control process is more complicated. For large-displacement engines, each cold start process will consume a large amount of ignition fuel, causing users to need to refill frequently, greatly reducing the convenience of vehicle use and bringing instability to users. In the field of vehicles, methanol hydrogen generators have potential application value. Vehicle-mounted methanol hydrogen generators can not only solve the problem of methanol engine cold start, but also reduce the design difficulty of methanol engines. However, due to the fast combustion speed of hydrogen, the wide explosion range, and the difficulty of leakage, the overall structure and reliability of vehicle-mounted methanol hydrogen generators are challenged.

[0004] Based on the above description, although the on-board methanol hydrogen generator can be used as a new direction to solve the cold start problem of methanol engines, there are no good measures to detect and prevent hydrogen safety management issues, and there are still high safety risks such as hydrogen leakage.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] In an exemplary embodiment, a vehicle-mounted methanol hydrogen generator safety management system is provided. In the embodiment of the present application, Figure 1 As shown, the vehicle-mounted methanol hydrogen generator safety management system includes: a methanol source, a methanol cracking reactor, a control unit, a remote control center, a cloud server and a sensor module;

[0045] The methanol source is connected to the on-board methanol hydrogen generator pipeline; the methanol cracking reactor is arranged inside the on-board methanol hydrogen generator; the methanol cracking reactor, the methanol source, and the sensor module are all electrically connected to the control unit; the control unit exchanges information with the remote control center; the remote control center exchanges data with the cloud server; a large database is implanted in the cloud server; the large database is used to store pressure data of the methanol cracking reaction;

[0046] The sensing module obtains the internal temperature of the methanol cracking reactor. When the internal temperature of the methanol cracking reactor reaches a set temperature value, the control unit generates a methanol delivery instruction; the methanol delivery instruction is used to open the methanol source to supply methanol; the sensing module obtains the pressure of the methanol supply. When the pressure of the methanol supply exceeds a set pressure value, the control unit generates a closing instruction; the closing instruction is used to close the methanol source;

[0047] The sensing module obtains the pressure inside the methanol cracking reactor; the remote control center obtains the pressure inside the methanol cracking reactor through the control unit, and retrieves the pressure data of the methanol cracking reaction stored in the big database, compares the pressure inside the methanol cracking reactor with the pressure data of the methanol cracking reaction stored in the big database, and obtains a comparison result; the remote control center determines whether there is an abnormality in the pressure inside the methanol cracking reactor based on the comparison result, and when there is an abnormality, the remote control center generates a cut-off signal; the cut-off signal is used to cut off the methanol supply.

[0048] Based on the above structure, in actual application, the vehicle-mounted methanol hydrogen generator is connected to the engine to provide power energy for the vehicle.

[0049] In another exemplary embodiment of the present application, in order to further control the methanol supply channel in real time, as shown in FIG. Figure 1 As shown, the methanol source used in the present application may include: a methanol tank and a methanol pump.

[0050] The methanol tank is connected to a vehicle-mounted methanol hydrogen generator (hereinafter referred to as a methanol hydrogen generator or a hydrogen generator) through a pipeline. A methanol pump is arranged on the connecting pipeline between the methanol tank and the vehicle-mounted methanol hydrogen generator. The methanol pump is electrically connected to a control unit. The control unit is used to control the opening and closing of the methanol pump.

[0051] In another exemplary embodiment of the present application, the sensing module includes: a temperature sensor T, a first pressure sensor P1 and a second pressure sensor P2.

[0052] The temperature sensor T, the first pressure sensor P1 and the second pressure sensor P2 are all electrically connected to the control unit. The temperature sensor T and the second pressure sensor P2 are arranged inside the methanol cracking reactor. The temperature sensor T is used to obtain the internal temperature of the methanol cracking reactor. The second pressure sensor P2 is used to obtain the pressure inside the methanol cracking reactor. The first pressure sensor P1 is used to obtain the pressure of the methanol supply.

[0053] In another exemplary embodiment of the present application, in order to be able to detect in real time whether there is a gas leak in the methanol cracking reactor, in this embodiment, the sensor module may also include: an H2 concentration sensor.

[0054] The H2 concentration sensor is electrically connected to the control unit. The H2 concentration sensor is arranged at the top of the interior of the vehicle-mounted methanol hydrogen generator. The H2 concentration sensor is used to obtain the hydrogen concentration inside the vehicle-mounted methanol hydrogen generator. The control unit determines whether there is a hydrogen escape phenomenon inside the vehicle-mounted methanol hydrogen generator based on the hydrogen concentration inside the vehicle-mounted methanol hydrogen generator.

[0055] Based on the above description, in actual application, the working principle of the vehicle-mounted methanol hydrogen generator safety management system provided by this application can be described as follows:

[0056] After the on-board methanol hydrogen generator receives the work instruction, the methanol cracking reactor starts to heat up. After the temperature reaches the set temperature (for example, 250°C is the set temperature. Different temperatures can be set according to the requirements of different OEMs in actual application), the methanol pump is turned on. The methanol pump pumps the liquid methanol in the methanol tank into the methanol cracking reactor. A first pressure sensor P1 is set on the methanol supply pipeline. The main function of the first pressure sensor P1 is to detect whether the methanol supply pressure is normal. A temperature sensor T is set in the methanol cracking reactor. The main function of the temperature sensor T is to detect whether the temperature in the methanol cracking reactor is within the normal range. A second pressure sensor P2 is set in the methanol cracking reactor. The main function of the second pressure sensor P2 is to detect whether the pressure change in the methanol cracking reactor is normal. In addition, an H2 concentration sensor is set above the inside of the hydrogen generator. The main function of the H2 concentration sensor is to detect whether there is H2 escape.

[0057] When the methanol cracking reactor starts working, the pressure inside the methanol cracking reactor is detected by the second pressure sensor P2. This pressure is transmitted to the remote control center through the control unit for real-time monitoring. At the same time, it is compared with the pressure data inside the methanol cracking reactor stored in the big database to observe in real time whether there is abnormal pressure in the methanol cracking reactor.

[0058] If it is detected that the pressure in the methanol cracking reactor is much lower than the pressure in the reaction stage in the big database, the first pressure sensor P1 and the temperature sensor T are synchronously detected to see if they are in the normal range. If the first pressure sensor P1 and the temperature sensor T are in the normal range, it proves that there is a gas leak in the methanol cracking reactor at this time, and the methanol cracking hydrogen production reaction needs to be stopped. At this time, the remote control center will send a signal to the vehicle terminal to switch the methanol pump or stop the engine. If the command signal is sent for a set time (for example, 30S) and still does not stop, the remote control center directly sends a cut-off signal to the control unit to stop the operation of the methanol pump or the engine.

[0059] When the H2 concentration sensor detects the hydrogen concentration and the pressure detected by the second sensor P2 in the methanol cracking reactor is abnormal, the methanol cracking reactor can be checked for leakage. When the H2 concentration sensor detects the hydrogen concentration and the pressure detected by the second sensor P2 in the methanol cracking reactor is within the normal range, the pipeline outside the methanol cracking reactor is checked for leakage.

[0060] Based on the above working principle, in practical application, such as Figure 2As shown, the implementation process of the vehicle-mounted methanol hydrogen generator safety management system provided by this application can be summarized as follows:

[0061] 1) After the methanol cracking reactor starts working, the parameter data of the hydrogen generator (i.e., the vehicle-mounted methanol hydrogen generator) at this time is sent to the remote control center.

[0062] 2) The remote control center integrates the real-time hydrogen generator data received into the big database, and uses the big database to determine whether the status inside the methanol cracking reactor is normal.

[0063] 3) Based on the data comparison results of big data, implement corresponding safety management measures for the hydrogen generator.

[0064] In this application, the big data database mainly collects the relevant important parameters of the entire working process of all methanol cracking hydrogen generators on the market. The big data parameters can be used to judge whether the methanol cracking hydrogen production process is normal. Through the safety supervision function of the remote control center, the vehicle safety can be improved and the risk of hydrogen leakage can be reduced.

[0065] In summary, the on-board methanol hydrogen generator safety management system provided in this application sends the main parameters of the methanol cracking hydrogen production process to the remote control center in real time by adding a remote control center and a big database data comparison, which can improve the monitoring capability and safety capability of the hydrogen status during the methanol cracking hydrogen production process and reduce the safety risks caused by hydrogen leakage.

[0066] Based on the same inventive concept, the embodiment of the present application also provides a vehicle-mounted methanol hydrogen generator safety management method applied to the vehicle-mounted methanol hydrogen generator safety management system involved above. The implementation scheme for solving the problem provided by the method is similar to the implementation scheme recorded in the above system, so the specific limitations in one or more vehicle-mounted methanol hydrogen generator safety management method embodiments provided below can refer to the limitations of the vehicle-mounted methanol hydrogen generator safety management system above, and will not be repeated here.

[0067] In an exemplary embodiment, Figure 3 As shown, a safety management method for a vehicle-mounted methanol hydrogen generator is provided, comprising:

[0070] Step 302: When an abnormal situation occurs in the vehicle-mounted methanol hydrogen generator, the type of abnormal situation is determined, and corresponding safety management measures are taken based on the existing abnormal situation.

The command signal is used to stop the vehicle engine and the methanol pump.

[0077] (5) The working status of the vehicle engine and the methanol pump is obtained in real time. If the vehicle engine and the methanol pump do not stop working within a set time after the command signal is generated, a cut-off signal is generated. The cut-off signal is used to control the methanol pump and the vehicle engine to stop working.

[0078] (6) When the internal temperature of the methanol cracking reactor is not within the set range, it is determined that the methanol cracking reactor is faulty and the operation of the methanol cracking reactor is stopped.

[0083] (2) When the pressure inside the methanol cracking reactor is within the set range, it is determined that there is a gas leak in the pipeline connected to the methanol cracking reactor, and the operation of the methanol cracking reactor is stopped.

[0084] (3) When the pressure inside the methanol cracking reactor is not within the set range, it is determined that there is a gas leak in the methanol cracking reactor, and the operation of the methanol cracking reactor is stopped.
