Description

Technical Field

[0001] This application relates to the field of gas leak detection technology, specifically to a cabinet, and also to a fuel cell including the aforementioned cabinet. Background Technology

[0002] The gas supply system of a fuel cell needs to pass through a desulfurization system to remove sulfides from the fuel gas, so that the fuel gas is purified before being introduced into the anode side of the fuel cell.

[0003] Desulfurization systems are generally integrated into desulfurization cabinets. However, there are many connecting pipes for the desulfurization system inside the cabinets, and the connection joints are prone to gas leakage, posing a significant safety hazard.

[0004] In addition, when the desulfurization cabinet is used outdoors, the pressure before and after the fan is easily affected by the external wind, which affects the fan flow and thus affects the detection of gas concentration. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a cabinet that can detect gas leaks in a timely manner, thereby reducing safety hazards.

[0006] The purpose of this application is also to provide a fuel cell including the aforementioned cabinet, so as to enable timely detection of gas leaks and thereby reduce safety hazards.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0012] A gas concentration sensor is used to detect the gas concentration in the storage chamber when the fan is working. The gas concentration sensor is disposed in the airflow path from the air inlet to the air outlet.

[0013] Alarm element, used to output alarm signal;

[0014] The controller is capable of triggering the alarm element when the gas concentration in the storage chamber reaches the target gas leakage concentration. The controller is connected to the gas concentration sensor and the alarm element.

[0015] Preferably, the cabinet also includes a pressure detection sensor for detecting the pressure difference between the inlet and outlet air of the fan or the pressure on the inlet side.

[0016] The controller is capable of adjusting the fan speed according to the inlet and outlet air pressure difference or the inlet side pressure to maintain the fan flow at the target flow. The controller is connected to the pressure detection sensor and the fan.

[0017] Preferably, in the above-mentioned cabinet, the pressure detection sensor is a differential pressure sensor, comprising:

[0018] The sensor body is used to detect the pressure difference between the inlet and outlet air of the fan, and the sensor body is installed on the cabinet.

[0019] An air intake side detection tube is connected to one end of the sensor body and extends to the air intake side of the fan;

[0020] An exhaust-side detection tube is connected to the other end of the sensor body and extends to the exhaust side of the fan.

[0021] Preferably, in the cabinet, a gas desulfurization container is provided in the storage cavity, and the gas desulfurization container is connected to an inlet pipe for inputting gas and an outlet pipe for outputting desulfurized gas.

[0022] Preferably, in the above-mentioned cabinet, both the air inlet pipe and the air outlet pipe pass through the bottom of the first side panel of the cabinet body;

[0023] The air inlet is located at the bottom of the first side plate and above the air inlet pipe and the air outlet pipe;

[0024] The air outlet is located at the top of the second side panel of the cabinet, and the first side panel and the second side panel are arranged opposite each other.

[0025] Preferably, in the above-mentioned cabinet, an electromagnetic valve is provided on the air inlet pipe, and the controller can control the electromagnetic valve to close when the gas concentration in the storage cavity reaches the target gas leakage concentration. The controller is connected to the electromagnetic valve.

[0026] Preferably, in the above-mentioned cabinet, the gas desulfurization container includes multiple desulfurization tanks connected in series or in parallel, and each desulfurization tank is equipped with a desulfurizing agent.

[0027] Preferably, in the above-mentioned cabinet, the exhaust side of the fan is arranged opposite to the air inlet side of the air outlet, and the gas concentration sensor is arranged on the air inlet side of the fan.

[0028] Preferably, in the above-mentioned cabinet, the air outlet is provided with a rainproof structure, the rainproof structure comprising:

[0029] Multiple rain shields are provided to shield the air outlet, and the rain shields are inclined downwards from the air outlet toward the outside of the storage cavity;

[0030] A rain cover is provided over the air outlet and extends from the air outlet into the storage cavity, and the fan is located at the end of the rain cover away from the air outlet.

[0031] As can be seen from the above technical solution, the cabinet provided in this application includes: a cabinet body having a storage cavity, with an air inlet and an air outlet connecting the outside to the storage cavity; a gas storage container and / or a gas desulfurization container, disposed within the storage cavity; a fan for driving outside air into the storage cavity through the air inlet and driving gas in the storage cavity out through the air outlet, the fan being disposed on the cabinet body; a gas concentration sensor for detecting the gas concentration in the storage cavity when the fan is working, the gas concentration sensor being disposed on the airflow path from the air inlet to the air outlet; an alarm element for outputting an alarm signal; and a controller capable of controlling the alarm element to sound an alarm when the gas concentration in the storage cavity reaches the target gas leakage concentration, the controller being connected to the gas concentration sensor and the alarm element.

[0032] The cabinet provided in this application has a gas storage container and / or a gas desulfurization container installed in its storage cavity. The gas storage container stores gas, and the gas desulfurization container allows gas to enter and exit. Therefore, there is a risk of gas leakage.

[0033] When the cabinet is in use, the fan is turned on. Driven by the fan, outside air is drawn into the storage chamber through the air inlet, flows through the storage chamber, and then flows out through the air outlet. The airflow path passes through the gas concentration sensor, which detects the gas concentration in the storage chamber and sends a gas concentration detection signal. After receiving the gas concentration detection signal, the controller compares the detected gas concentration in the storage chamber with the target gas leak concentration. When the detected gas concentration in the storage chamber reaches the target gas leak concentration, the controller activates the alarm element to sound an alarm and outputs an alarm signal. This allows for timely detection of gas leaks, enabling timely safety measures to be taken and reducing safety hazards.

[0034] In addition, this application places the gas concentration sensor in the airflow path from the air inlet to the air outlet. The fan can promote the flow of gas in the storage cavity to the gas concentration sensor, which is more conducive to the detection of gas concentration. At the same time, the fan keeps the cabinet in a ventilated state, which also reduces safety hazards.

[0044] This application provides a cabinet and a fuel cell that enable timely detection of gas leaks, thereby reducing safety hazards.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] like Figures 1-5As shown, the cabinet provided in this embodiment includes: a cabinet 1 having a storage cavity, with an air inlet 1-1 and an air outlet 1-2 connecting the outside to the storage cavity; a gas storage container and / or a gas desulfurization container disposed within the storage cavity; a fan 3 for driving outside air into the storage cavity through the air inlet 1-1 and driving gas in the storage cavity to exit through the air outlet 1-2, the fan 3 being disposed on the cabinet 1; a gas concentration sensor 5 for detecting the gas concentration in the storage cavity when the fan 3 is operating, the gas concentration sensor 5 being disposed on the airflow path from the air inlet 1-1 to the air outlet 1-2; an alarm element for outputting an alarm signal; and a controller for controlling the alarm element to sound an alarm when the gas concentration in the storage cavity reaches a target gas leakage concentration, the controller being connected to the gas concentration sensor 5 and the alarm element.

[0047] The cabinet provided in this application has a gas storage container and / or a gas desulfurization container installed in its storage cavity. The gas storage container stores gas, and the gas desulfurization container allows gas to enter and exit. Therefore, there is a risk of gas leakage.

[0048] When the cabinet is in use, fan 3 is turned on. Driven by fan 3, outside air is drawn into the storage chamber through air inlet 1-1, flows through the storage chamber, and then flows out through air outlet 1-2. The airflow path passes through gas concentration sensor 5, which detects the gas concentration in the storage chamber and sends a gas concentration detection signal. After receiving the gas concentration detection signal, the controller compares the detected gas concentration in the storage chamber with the target gas leakage concentration. When the detected gas concentration in the storage chamber reaches the target gas leakage concentration, the controller controls the alarm element to sound an alarm and outputs an alarm signal. This allows for timely detection of gas leaks, enabling timely safety measures to be taken and reducing safety hazards.

[0049] In addition, this application places the gas concentration sensor 5 in the airflow path from the air inlet 1-1 to the air outlet 1-2. The fan 3 can promote the flow of gas in the storage cavity to the gas concentration sensor 5, which is more conducive to the detection of gas concentration. At the same time, the fan 3 keeps the cabinet in a ventilated state, which also reduces safety hazards.

[0050] It should be noted that the aforementioned gaseous gases refer to gases such as hydrogen, natural gas, coal gas, and liquefied petroleum gas, as well as fuels such as methanol.

[0051] The alarm element can output an alarm signal through an audible alarm and / or an alarm light. This application can, after an alarm is triggered, increase the airflow of fan 3 via the controller to promptly reduce the gas concentration in the storage chamber as a preliminary safety measure.

[0052] When the cabinet is used outdoors, the front and rear pressure of fan 3 is more easily affected by the external wind, which affects the flow rate of fan 3, i.e., the air volume. Since the air volume of fan 3 corresponds to the target gas leakage concentration, the external wind will affect the detection of gas concentration.

[0053] Preferably, the cabinet provided in the above embodiment further includes a pressure detection sensor for detecting the pressure difference between the inlet and outlet air of the fan 3 or the pressure on the inlet side; wherein, the controller can adjust the speed of the fan 3 according to the pressure difference between the inlet and outlet air of the fan 3 or the pressure on the inlet side so that the flow rate of the fan 3 is maintained at the target flow rate, and the controller is connected to the pressure detection sensor and the fan 3.

[0054] In this embodiment, a pressure sensor detects the inlet and outlet air pressure difference or the inlet side pressure of fan 3 and sends an air pressure detection signal. After receiving the air pressure detection signal, the controller compares the detected inlet and outlet air pressure difference or the inlet side pressure of fan 3 with the target air pressure difference or the target inlet air pressure. Based on the comparison result, the controller adjusts the fan speed of fan 3 so that the fan flow rate is maintained at the target flow rate, thereby ensuring that the cabinet exhausts air at a certain volume and reducing the impact of external wind on leakage detection.

[0055] like Figure 3-5 As shown in the specific embodiment, the pressure detection sensor is a differential pressure sensor 4, including a sensor body 4-1, used to detect the pressure difference between the inlet and outlet of the fan 3. The sensor body 4-1 is mounted on the cabinet 1; an inlet side detection tube 4-3 is connected to one end of the sensor body 4-1 and extends to the inlet side of the fan 3; and an outlet side detection tube 4-2 is connected to the other end of the sensor body 4-1 and extends to the outlet side of the fan 3.

[0056] In this embodiment, a differential pressure sensor 4, consisting of a sensor body 4-1, an inlet-side detection tube 4-3, and an exhaust-side detection tube 4-2, is used to detect the inlet and exhaust pressure difference across the fan 3. When the outside wind causes a change in the pressure difference across the fan 3 within a certain period of time, the controller adjusts the speed of the fan 3 based on the measured inlet and exhaust pressure difference and the characteristics of the fan 3's speed and flow rate. This ensures that the flow rate of the fan 3 remains within the set target range even when there is outside wind, thus maintaining the detection function for gas leaks of a specific concentration unaffected.

[0057] Alternatively, the pressure sensor of this application can also detect only the air intake pressure of the fan 3 and adjust the fan speed according to the air intake pressure to achieve the same goal of maintaining the airflow of the fan 3 within the set target range.

[0058] In one specific embodiment, a gas desulfurization container is installed inside the storage cavity. The gas desulfurization container is connected to an inlet pipe 7 for inputting gas and an outlet pipe 8 for outputting desulfurized gas. In this way, the cabinet can achieve the desulfurization function. Gas enters from the inlet pipe 7, is desulfurized by the gas desulfurization container, and flows out from the outlet pipe 8, providing purified gas for equipment such as fuel cells. The cabinet structure of this application can promptly detect leaks in the gas desulfurization container and connecting joints, thereby taking timely safety measures and reducing safety hazards.

[0059] Of course, the cabinet of this application can also be used solely for storing gas. If a gas storage container is installed inside the storage cavity, the cabinet structure of this application can detect gas storage container leaks in a timely manner, thereby taking timely safety measures and reducing safety hazards.

[0060] like Figure 3 As shown, the air inlet pipe 7 and the air outlet pipe 8 are both installed at the bottom of the first side panel of the cabinet 1; the air inlet 1-1 is located at the bottom of the first side panel and above the air inlet pipe 7 and the air outlet pipe 8; the air outlet 1-2 is located at the top of the second side panel of the cabinet 1, and the first side panel and the second side panel are arranged opposite to each other.

[0061] Since natural gas is lighter than air, in this embodiment, the air inlet 1-1 of cabinet 1 is positioned close to the upper part of the air inlet pipe 7 and the air outlet pipe 8, and the air inlet 1-1 and the air outlet 1-2 are staggered, with the air inlet lower and the air outlet higher. This facilitates the air carrying the leaked natural gas to the natural gas concentration sensor 5 and expelling it from the air outlet 1-2, while avoiding dead zones where leaked natural gas can accumulate, thus reducing safety hazards. Furthermore, the air inlet pipe 7 and the air outlet pipe 8, which supply natural gas, are located in the same position on cabinet 1 for easy installation and maintenance.

[0062] In a further technical solution, a solenoid valve 6 is installed on the intake pipe 7, such as... Figure 3 As shown, the controller can close the solenoid valve 6 when the gas concentration in the storage chamber reaches the target gas leakage concentration. The controller is connected to the solenoid valve 6. When the gas concentration in the cabinet reaches the target gas leakage concentration, the controller activates the alarm and simultaneously closes the solenoid valve 6 to shut off the gas intake, thus achieving a safety protection function.

[0063] like Figure 2 As shown, the gas desulfurization container includes multiple desulfurization tanks 2 connected in series or parallel, each containing a desulfurizing agent. The cabinet houses these multiple desulfurization tanks 2. Gas enters through the inlet pipe 7, passes through the multiple desulfurization tanks 2, and then flows out through the outlet pipe 8. The multiple desulfurization tanks 2 provide a larger gas processing capacity and better desulfurization effect. However, the large number of desulfurization tanks 2 results in numerous connection joints, posing a risk of gas leakage. The cabinet structure of this application can promptly detect leaks in the gas desulfurization container and its connection joints, allowing for timely safety measures and reducing potential safety hazards.

[0064] To better detect gas leaks, the exhaust side of fan 3 is positioned opposite the inlet side of air outlets 1-2, and the gas concentration sensor 5 is located on the inlet side of fan 3. Figure 3-5 As shown, the gas concentration sensor 5 is arranged near the air inlet side of the fan 3, that is, the air collection position of the fan 3. When the gas leakage exceeds the expected value, the gas concentration reaching the fan 3 will exceed the target gas leakage concentration, and the controller will control the alarm element to sound an alarm. The air volume at this position is relatively large, which is more conducive to detecting gas leakage. Of course, the gas concentration sensor 5 can also be set at other positions in the airflow path from the air inlet 1-1 to the air outlet 1-2, such as in the middle of the line connecting the air inlet 1-1 and the air outlet 1-2.

[0065] To further optimize the above technical solution, a rainproof structure is provided at the air outlet 1-2. The rainproof structure includes: multiple rain-shielding strips covering the air outlet 1-2, the rain-shielding strips sloping downwards from the air outlet 1-2 towards the outside of the storage cavity; a rainproof cover 1-3, covering the air outlet 1-2 and extending from the air outlet 1-2 into the storage cavity; and a fan 3 located at the end of the rainproof cover 1-3 away from the air outlet 1-2. In this embodiment, the fan 3 is fixedly installed on the rainproof cover 1-3. The rainproof cover 1-3 provides fixed support for the fan 3 while increasing the distance between the fan 3 and the air outlet 1-2. Furthermore, the rain-shielding strips at the air outlet 1-2 provide rain protection for the fan 3, improving operational reliability.

[0066] This application also provides a fuel cell, including a fuel cell body and a cabinet for supplying gas to the fuel cell body. The cabinet is the same as the one provided in any of the above embodiments, which enables timely detection of gas leaks, thereby reducing safety hazards.
