Description

Technical Field

[0002] In the hydrogen production process, a set of 1000NM3 / H alkaline electrolyzer hydrogen production device produces hydrogen at a pressure of 1.6MPa. After the hydrogen passes through the hydrogen separation skid and hydrogen purification skid (drying and purification), the hydrogen purity exceeds 99.999%, and the hydrogen is transported to the buffer tank. The hydrogen compressor increases the hydrogen pressure from the buffer tank from 1.6MPa to 20MPa, and then transports it to the filling device through the outdoor underground hydrogen transmission pipeline. The filling device filters it again and fills the hydrogen into the hydrogen bundle truck.

[0003] However, during the transportation of hydrogen, due to the poor environment of outdoor underground pipelines, dust, moisture and other impurities will be added to the hydrogen, affecting the purity of the hydrogen and thus the product quality. In addition, when the filter device of the filling device is blocked or the moisture content of the hydrogen exceeds the standard, the filling device will automatically trip, but the electrolyzer, hydrogen compressor and other devices will still operate normally. At this time, the hydrogen generated is directly discharged, causing great waste and creating great safety hazards. Utility Model Content

[0032] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0033] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0034] The following refers to Figures 1 to 3 to describe an automatic filling device for a tube bundle vehicle according to some embodiments of the present utility model.

[0035] Some embodiments of the present application provide an automatic filling device for a tube bundle vehicle.

[0036] As Figures 1 to 3 shown, the first embodiment of the present utility model proposes an automatic filling device for a tube bundle vehicle, which is arranged between a hydrogenation device and a filling and releasing device, and includes a differential pressure testing unit, a filtering unit, and an alarm protection device;

[0037] The differential pressure testing unit includes a first pressure testing unit and a second pressure testing unit. The first pressure testing unit is connected to the hydrogenation device, and the first pressure testing unit is used to obtain the first pressure value and the first flow rate value at the inlet of the hydrogenation device. The first pressure testing unit is connected to the inlet end of the filtering unit, and the output end of the filtering unit is connected to the second pressure testing unit. The second pressure testing unit is used to obtain the second pressure value and the second flow rate value at the output end of the filtering unit.

[0038] The filtering unit is used to screen the gas to be filled. The first pressure testing unit and the second pressure testing unit in the differential pressure testing unit can measure the gas to be filled respectively upstream and downstream of the filtering unit, and can obtain the flow rate values and pressure values before and after filtering. By measuring the flow rate values and pressure values before and after filtering, it is judged whether the pressure and flow rate fluctuations of the gas are within the normal fluctuation range. In the present application, the gas to be filled is taken as hydrogen as an example for illustration. An automatic filling device for a tube bundle vehicle can improve the gas quality of filling hydrogen into the tube bundle vehicle.

[0039] The alarm protection device is respectively connected to the second pressure test unit and the hydrogenation device. When the first pressure value and the second pressure value exceed the set pressure threshold, or the first flow rate value and the second flow rate value exceed the set flow rate threshold, the alarm protection device releases alarm information. That is to say, when the first pressure value and the second pressure value exceed the safety value, the alarm protection device will release alarm information for warning. The safety value is the set pressure threshold. Similarly, it is also possible to judge whether the flow rate value exceeds the safety value through the first flow rate value and the second flow rate value. At this time, the safety value is the set flow rate threshold.

[0040] When the alarm protection device releases alarm information, it will also close the intake port of the hydrogenation device or the filling port of the filling release device, that is, stop the filling process. Herein, the alarm information may be at least one of a sound element, an odor element, a visual element, and a text element. It is easy to understand that the sound element can be understood as an alarm sound effect, the odor element may include a safety gas with an irritating odor, the visual element may include a signal indicator light, and the text element includes text alarm information.

[0041] It improves the degree of automated operation of the equipment, improves the operation reliability of the equipment, reduces the equipment failure rate, reduces the operation energy consumption of the equipment, shuts down an automatic filling device for a tube bundle vehicle through automatic interlock, increases the operation reliability of the equipment, reduces the loss of direct external discharge of hydrogen in the case where the filling device shuts down while the electrolytic cell does not shut down, and improves the economy.

[0042] More specifically, in a preferred embodiment, an automatic filling device for a tube bundle vehicle includes at least two of the filtering units, and at least one of the two filtering units remains in a startup state. During normal production operation, to ensure the uninterrupted production process, the two filtering units can be in a one-use-one-backup state. When one of the filtering device fails, it automatically switches to the other filtering device to ensure that the equipment does not shut down.

[0043] More specifically, the filtering unit includes a primary filtering mechanism and a secondary filtering mechanism, and the primary filtering mechanism and the secondary filtering mechanism are arranged in sequence along the gas inlet direction to the gas outlet direction. The primary filtering mechanism is at least used to screen out particulate impurities, and the secondary filtering mechanism is at least used to screen out gaseous impurities. In this way, the screening process can simultaneously achieve the screening of solid particles and gaseous impurities of hydrogen. Of course, the primary filtering mechanism and the secondary filtering mechanism in each filtering unit can also be set to multiple, and also adopt a one-use-one-backup state to ensure the normal operation of production.

[0044] Further, the filtering unit further includes a detection device, which is arranged at the gas discharge end of the filtering unit, and the detection device is used to detect the content of particulate impurities and the content of gaseous impurities in the gas at the gas discharge end. Specifically, during normal operation, the moisture and dust in hydrogen can be detected. The detection device can also be adjustably connected to the primary filtering mechanism and the secondary filtering mechanism. By controlling the screening intensity of the primary filtering mechanism and the secondary filtering mechanism, the filtering depth can be increased, the screening effect can be improved, the dryness and cleanliness of hydrogen can be ensured, and the quality of the filled hydrogen can be improved.

[0045] More specifically, since common filling devices are placed outdoors and are connected to outdoor underground pipelines, they are outdoor open-air devices and are greatly affected by dust, rain, etc. The operating environment is poor, which affects the use accuracy, service life, and use quality of the equipment. Therefore, an automatic filling device for an infusion vehicle provided in this application further includes a protection mechanism, and the differential pressure test unit, the filtering unit, and the alarm protection device are arranged in the protection mechanism. Preferably, the differential pressure test unit, the filtering unit, and the alarm protection device are detachably arranged in the protection mechanism, and the three can be adjusted, maintained, and replaced according to the actual production situation, making the operation more convenient.

[0046] More specifically, the protection mechanism includes a box body 2 and a cover body 1. The cover body 1 is detachably connected to the cover body 1, and the projection of the box body 2 in the vertical direction completely falls within the range of the cover body 1. As Figure 2 shown, the cover body 1 can cover the upper part of the box body 2. The differential pressure test unit, the filtering unit, and various devices such as the alarm protection device are placed in the box body 2. The cover body 1 can protect the various devices in the box body 2, prevent them from contacting the external environment, and reduce the influence of environmental factors on the service life of the device.

[0047] In a preferred embodiment, a water guide body 3 is further arranged on the periphery of the cover body 1, and the extending direction of the water guide body 3 forms an angle with the extending direction of the length or width of the cover body 1. As Figure 3 shown, the water guide body 3 is arranged at an angle, which can guide the water dripping on the cover body 1 to flow down quickly, reduce the residence time, and at the same time guide its dripping. The water guide body 3 arranged on the periphery of the cover body 1 can also protect the periphery of the cover body 1, prevent rainwater from entering the gap between the cover body 1 and the box body 2 from the side, and play a shielding effect.

[0048] In a preferred embodiment, the water guiding body 3 includes a convex water guiding portion 31 disposed away from the box body 2, and an extension portion 32 connected to the convex water guiding portion 31. The extension portion 32 is disposed away from the top of the cover body 1, and at least a part of the extension portion 32 is arc-shaped. It is easy to understand that the convex water guiding portion 31 can enable water droplets to quickly gather and guide the water droplets to flow down in a stream. The extension portion 32 can be disposed at an angle or in a straight line with the convex water guiding portion 31. The extension portion 32 with a partial arc shape can enable water droplets to gather at the arc-shaped convex position, making it more concentrated.

[0049] An automatic filling device for a tube bundle vehicle further includes a cleaning device. The cleaning device is disposed in the protection mechanism, and the cleaning area of the cleaning device covers the differential pressure testing unit, the filtering unit, and the alarm protection device. It can clean the space of the box body 2. Specifically, the cleaning device can include an electric blowing device and a drying device to ensure the dryness and cleanliness inside the box body 2.

[0050] In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiments or examples. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0051] Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
