Technical Field

[0001] This application relates to the field of gas detection technology, and in particular to a gas detection chamber and a gas detection device. Background Technology

[0002] With increasing industrialization and environmental issues, the detection of toxic and hazardous gases is becoming increasingly critical, as leaks and accumulations in environments such as grain silos and industrial settings pose significant risks. Conducting large-scale, long-term gas detection experiments in the field is slow to respond, costly, and may disrupt normal production operations.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] Therefore, it is necessary to provide a gas detection chamber and gas-liquid separation system to address the problems of slow response, high cost, and potential interference with normal production operations when conducting large-scale and long-term gas detection experiments in the field.

[0005] Firstly, a gas detection chamber includes:

[0006] The container body is provided with a receiving cavity;

[0007] An air intake structure is connected to the chamber and located outside the receiving cavity. The air intake structure is provided with an air intake channel for communicating with the receiving cavity.

[0008] A liquid storage structure, connected to the container body and located within the receiving cavity, the liquid storage structure having a liquid storage tank communicating with the receiving cavity; and

[0009] A connector, which is connected to the chamber body, is used to connect to a gas detector.

[0010] In one embodiment, the gas detection chamber further includes an exhaust structure connected to the chamber body and located outside the receiving cavity. The exhaust structure is provided with an exhaust channel for communicating with the receiving cavity.

[0011] In one embodiment, the gas detection chamber further includes an exhaust switch connected to the chamber body and located outside the receiving cavity, the exhaust switch being electrically connected to the exhaust structure.

[0012] In one embodiment, the gas detection chamber further includes a gas-driven structure, which includes a power component located outside the receiving cavity and a movable component located inside the receiving cavity. Both the power component and the movable component are connected to the chamber body, and the driving end of the power component is connected to the movable component. The power component is used to drive the movable component to move.

[0013] In one embodiment, the gas detection chamber further includes a gas-driven switch connected to the chamber body and located outside the receiving cavity, the gas-driven switch being electrically connected to the gas-driven structure.

[0014] In one embodiment, the gas detection chamber further includes a pressure detection structure, which includes a housing, a display, a motherboard with a pressure sensor, and a battery. The motherboard is electrically connected to the display and the battery. The housing has a placement cavity and a window and a gas detection channel communicating with the cavity. The battery and the display are located inside the placement cavity, with the display facing the window. The motherboard is located inside the gas detection channel. The pressure detection structure is located outside the chamber, and the housing is connected to the chamber. The gas detection channel communicates with the cavity.

[0015] In one embodiment, the chamber includes a first plate, a second plate, and a third plate connected to each other. The first plate and the third plate are disposed opposite each other along the height direction of the chamber, and the second plate is disposed between the first plate and the third plate along the height direction of the chamber. The first plate, the second plate, and the third plate enclose the receiving cavity. The air inlet structure, the liquid storage structure, and the connector are disposed in any one of the first plate, the second plate, and the third plate.

[0016] In one embodiment, the compartment further includes a fourth plate that is movably connected to any one of the first plate, the second plate, and the third plate, and the fourth plate is used to cover the receiving cavity.

[0018] In a second aspect, there is a gas-liquid detection device, wherein the gas detection device includes a gas detection chamber as described in the first aspect.

[0019] The aforementioned gas detection chamber is a relatively independent and compact space. Compared to the tens of thousands of square meters of space in a real-world environment, the time required for gas to diffuse within the smaller chamber is significantly reduced. For example, when simulating a localized environment in an industrial plant, the distance from a corner of the actual plant to the detection point is long, resulting in prolonged gas diffusion. However, within the chamber, the shorter distance allows for uniform gas distribution, reaching the required stable state for detection much faster. The gas detection chamber integrates gas intake, liquid storage, and detection connection functions into one unit, eliminating the need for dispersed supporting facilities across a vast field and greatly reducing initial construction costs.

Detailed Implementation

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] Please see Figure 1This application provides a gas detection chamber 100, including a chamber body 1, an air inlet structure 2, and a liquid storage structure 3 (see [link to application]). Figure 2 4. Connector 5. Exhaust structure 6. Exhaust switch 7. Gas drive structure (see also) Figure 2 8. Gas-driven switch; 9. Gas pressure detection structure.

[0027] Please see Figure 1 and Figure 2 In some embodiments, the chamber 1 is provided with a receiving cavity 17. An air intake structure 2 is connected to the chamber 1 and located outside the receiving cavity 17. The air intake structure 2 has an air intake channel for communicating with the receiving cavity 17. A liquid storage structure 3 is connected to the chamber 1 and located inside the receiving cavity 17. The liquid storage structure 3 has a liquid storage tank that communicates with the receiving cavity 17. A connector 4 is connected to the chamber 1 and is used to connect to a gas detector. The air intake structure 2 can introduce toxic and harmful gases into the chamber 1, and the liquid storage structure 3 can collect easily volatile toxic and harmful liquids to adjust the humidity inside the gas detection chamber 100, thereby enabling the gas detection chamber 100 to simulate specific spaces such as grain silos and industrial plants. After the connector 4 is connected to the gas detector, the gas detector detects the types of toxic and harmful gases inside the gas detection chamber 100.

[0028] The aforementioned gas detection chamber 100 is a relatively independent and compact space. Compared to the tens of thousands of square meters of space in a real-world environment, the time required for gas to diffuse within the smaller containment chamber 17 is significantly reduced. For example, when simulating a localized environment in an industrial plant, the distance from a corner of the actual plant to the detection point is long, resulting in prolonged gas diffusion. However, within the chamber 1, the gas can be evenly distributed over a short distance, reaching the stable state required for detection more quickly. The gas detection chamber 100 integrates gas intake, liquid storage, and detection connection functions into one unit, eliminating the need for scattered supporting facilities across a vast field. The chamber 1 and its supporting components can be constructed in a single investment, greatly reducing upfront construction costs.

[0029] In optional embodiments, the gas detector may be an infrared gas detector, an electrochemical gas detector, an absorption gas detector, etc.

[0030] In an optional embodiment, the air intake structure 2 can be a valve, an air intake pipe, etc. The air intake structure 2 can be connected to a gas source such as a gas cylinder or a gas supply pipeline. The gas source can control the flow rate and regulate the pressure of toxic and harmful gases through the valve, thereby enabling the gas source to introduce a fixed amount of toxic and harmful gases into the chamber 1.

[0031] In an optional embodiment, the liquid storage structure 3 is used to collect easily volatile toxic or harmful liquids. The required liquid volume is calculated based on the mass concentration after evaporation. This can be calculated using a mass concentration formula. Where c is the mass concentration of the toxic and harmful gas, m is the mass of the toxic and harmful liquid, and V is the volume of the cavity 17 of the storage tank 1. This allows control over the concentration of the toxic and harmful gas after it evaporates from the liquid storage structure 3.

[0032] To accelerate the evaporation of toxic and hazardous liquids, in an optional embodiment, the liquid storage structure 3 includes a heater and a heating platform, with the heating platform having a liquid storage tank. The heater heats the heating platform, thereby causing the toxic and hazardous liquids to evaporate rapidly.

[0033] In alternative implementations, a resistance heater, an infrared heater, or an induction heater may be used.

[0034] In an optional implementation, the connector 4 may be a threaded connector plug, a bayonet connector plug, or the like.

[0035] Please see Figure 1 In some embodiments, the exhaust structure 5 is connected to the chamber 1 and located outside the receiving cavity 17. The exhaust structure 5 is provided with an exhaust channel for communicating with the receiving cavity 17. The exhaust structure 5 enables the discharge of toxic and harmful gases after the test is completed.

[0036] Please see Figure 1 In an optional embodiment, the exhaust structure 5 includes an exhaust fan 51 and an exhaust pipe 52. The exhaust fan 51 is fixed to the chamber 1 and located outside the receiving cavity 17, and the exhaust pipe 52 communicates with both the exhaust fan 51 and the receiving cavity 17. By activating the exhaust fan 51, toxic and harmful gases inside the chamber 1 are transported out through the exhaust pipe 52.

[0037] Please see Figure 1 In some embodiments, the exhaust switch 6 is connected to the chamber 1 and located outside the receiving cavity 17, and the exhaust switch 6 is electrically connected to the exhaust structure 5. By providing the exhaust switch 6, it is easy to open or close the exhaust structure 5. In an optional embodiment, the exhaust switch 6 is electrically connected to the exhaust fan 51, and the exhaust switch 6 can control the opening and closing of the exhaust fan 51.

[0038] Please see Figure 3 In some embodiments, the gas-driven structure 7 includes a power component 71 located outside the receiving cavity 17 and a movable component 72 located inside the receiving cavity 17. Both the power component 71 and the movable component 72 are connected to the chamber 1. The drive end of the power component 71 is connected to the movable component 72, and the power component 71 is used to drive the movable component 72 to move. The gas-driven structure 7 accelerates the flow and circulation of gas within the chamber 1, speeds up the evaporation of toxic and harmful liquids, and ensures that the test conditions within the chamber 1 remain consistent and stable.

[0039] In optional embodiments, the power component 71 may be a drive fan, a drive pump, etc. The movable component 72 may be a blade, an impeller, etc. The movable component 72 may rotate around its own axis, or the movable component 72 may swing left and right. The embodiments of this application do not limit the movement mode of the movable component 72.

[0040] Please see Figure 1 In some embodiments, the gas-driven switch 8 is connected to the chamber 1 and located outside the receiving cavity 17, and the gas-driven switch 8 is electrically connected to the gas-driven structure 7. The gas-driven switch 8 facilitates control of the gas-driven structure 7, enabling easy control of its opening and closing.

[0041] In an optional implementation, the gas-driven switch 8 can control the opening and closing of the drive fan or drive pump.

[0042] In some embodiments, the pressure detection structure 9 includes a housing, a display, a motherboard with a pressure sensor, and a battery. The motherboard is electrically connected to the display and the battery. The housing has a placement cavity and a window and a gas detection channel communicating with the placement cavity. The battery and the display are located inside the placement cavity, with the display facing the window. The motherboard is located inside the gas detection channel. The pressure detection structure 9 is located outside the chamber 1, and the housing is connected to the chamber 1. The gas detection channel communicates with the receiving cavity 17. It is understood that when the pressure detection structure 9 is connected to the chamber 1, the gas detection channel communicates with the receiving cavity 17 of the chamber 1. Toxic and harmful gases in the receiving cavity 17 enter the gas detection channel, and the pressure sensor on the motherboard detects the pressure of the toxic and harmful gases. The pressure value is displayed on the window by the display. The pressure detection structure 9 facilitates the control of the pressure inside the chamber 1.

[0043] In an optional implementation, the pressure detection structure 9 may be a pressure gauge or the like.

[0044] In optional embodiments, the container 1 can be a spherical container, a square container, or other shapes.

[0045] In an optional embodiment, the volume of the receiving cavity 17 of the compartment 1 is 0.5m³. 3 1m 3 2m 3 3m 3 wait.

[0046] Please see Figure 1In some embodiments, the chamber 1 includes a first plate 11, a second plate 12, and a third plate 13 connected together. The first plate 11 and the third plate 13 are arranged opposite each other along the height direction of the chamber 1, and the second plate 12 is disposed between the first plate 11 and the third plate 13 along the height direction of the chamber 1. The first plate 11, the second plate 12, and the third plate 13 enclose a receiving cavity 17. An air inlet structure 2, a liquid storage structure 3, and a connector 4 are disposed on any one of the first plate 11, the second plate 12, and the third plate 13. The air inlet structure 2, the liquid storage structure 3, and the connector 4 can be mounted on any plate, and the first plate 11, the second plate 12, and the third plate 13 provide a large area of ​​mounting surface. Compared with a complex-shaped chamber 1, a flat plate is easier to drill, weld, rivet, or fix various components with screws, reducing installation difficulty, improving installation accuracy and efficiency, and reducing the risk of gas leakage due to installation errors. The first plate 11, the second plate 12, and the third plate 13 can form a stable frame, supporting and restraining each other, which can enhance the overall rigidity of the silo body 1.

[0047] In an optional embodiment, the air intake structure 2, the liquid storage structure 3, and the connector 4 are all located on the second side plate.

[0048] Please see Figure 1 In some embodiments, the chamber 1 further includes a fourth plate 14, which is movably connected to any one of the first plate 11, the second plate 12, and the third plate 13. The fourth plate 14 is used to cover the receiving cavity 17. The fourth plate 14 can be opened flexibly, providing a direct and unobstructed operating entry for staff, thereby improving operational convenience.

[0049] In an optional embodiment, the fourth plate 14 may be movably connected to the first plate 11, or movably connected to the second plate 12, or movably connected to the third plate 13.

[0050] In an optional embodiment, the chamber 1 further includes a seal 18 disposed between the fourth plate 14 and the first plate 11, the second plate 12 and the third plate 13, and the seal 18 is used to seal the receiving cavity 17 when the fourth plate 14 is closed.

[0051] In an optional embodiment, the seal 18 may be a sealing strip or a sealing ring, etc., and the seal 18 is fixed on the fourth plate 14.

[0052] Please see Figure 1 In some embodiments, the gas detection chamber 100 further includes a chamber support 15 and rollers 16. The chamber support 15 is located at the bottom of the chamber 1 along its own height direction, and the rollers 16 are located at the bottom of the chamber support 15. The chamber support 15 increases the placement height of the gas detection chamber 100, facilitating operation. The rollers 16 facilitate the movement of the gas detection chamber 100.

[0053] Secondly, embodiments of this application also provide a gas detection device, which includes the gas detection chamber 100 of the first aspect. The gas detection device also includes a gas detector.
