Description

Technical Field

[0001] This utility model relates to the field of environmental flue gas analysis technology, specifically, to a device for the protection, collection, detection, and early warning of gaseous pollutants for a quick-connect plug in a gas circuit. Background Technology

[0002] Quick-connect gas line connectors enable rapid and convenient connection of pipelines, and are therefore widely used in many experimental devices.

[0003] However, due to their quick-connect nature, quick-connect plugs for gas lines usually require rapid insertion and removal. As the frequency of operation increases, there is a certain risk of local deformation, which can easily lead to leakage. This risk is closely related to the usage environment and the user's skill level.

[0004] When equipment pipelines are connected to harmful gases for experiments, quick-connect plugs pose a certain risk of leakage, which can easily endanger the health of workers. Currently, only environmental gas detectors can provide alarms for specific harmful gases. However, leaks from quick-connect plugs may only cause harm in a localized area, with the concentration dropping significantly after spreading into the environment. Environmental gas detectors are usually installed on ceilings, walls, etc., to monitor the harmfulness of gases in a relatively larger environment. They are not capable of detecting such minor leaks, but workers who are close to the experimental equipment are still at an unknown risk.

[0005] Therefore, there is currently no effective means to detect the leakage risk caused by the high frequency and long service life of this type of quick-connect plug.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a device specifically designed for detecting gas leak risks in quick-connect gas circuits, ensuring the safety of experimental environments, and protecting against, collecting, and detecting gaseous contaminants in quick-connect gas circuits.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a gas pollutant protection, collection and detection early warning device for a gas circuit quick-connect plug, including a protective cover, a suction mechanism, a gas detector and a waste gas treatment device;

[0009] The protective cover includes a cover body, at least two connection ports formed on the cover body, and a hollow cavity formed in the cover body. The hollow cavity is used to house the quick-connect plug for air passage, and the connection ports are used to allow the pipes connected to the quick-connect plug to pass through.

[0010] The suction mechanism is connected to the hollow chamber inside the protective cover through a dedicated pipeline, and is used to extract the gas inside the hollow chamber.

[0011] The gas detector is connected to the outlet end of the suction mechanism to detect the extracted gas.

[0012] The waste gas treatment equipment is connected to the outlet of the gas detector for purifying the gas.

[0013] Based on the above, the protective cover includes a first cover and a second cover, which are detachably connected together, and the hollow cavity is formed inside after the first cover and the second cover are assembled.

[0014] Based on the above, a connection port is provided at each of the two horizontal ends of the first cover, and a connection port is provided on the outer side of the second cover, with the three connection ports forming a T-shape.

[0015] Based on the above, each of the connection ports is provided with a flexible sealing structure and a sealing cover.

[0016] Based on the above, the dedicated pipeline connecting the suction mechanism and the hollow cavity of the protective cover is equipped with a bypass, and the bypass and the dedicated pipeline switch flow directions through a three-way valve.

[0017] Based on the above, the suction mechanism is a peristaltic pump.

[0018] Based on the above, the cover is generally rectangular in shape.

[0019] Based on the above, the waste gas treatment equipment is equipped with a multi-layer filtration structure.

[0020] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model uses a protective cover to cover the quick-connect plug, forming a relatively closed space. Then, an external suction mechanism is connected to draw the airflow inside the protective cover to a gas detector for testing.

[0021] This device can be used for both routine inspections of quick-connect gas lines, ensuring their safety by periodically checking the quick-connect gas lines in use, and routine monitoring of quick-connect gas lines. It is generally used in high-risk experiments to monitor the status of quick-connect gas lines in real time and eliminate potential safety hazards. Attached Figure Description

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0030] like Figures 1-5 As shown, a gaseous pollutant protection, collection, detection and early warning device for a gas circuit quick-connect plug includes a protective cover 1, a suction mechanism 2, a gas detector 3, and a waste gas treatment device 4.

[0031] The protective cover 1 includes a cover body, at least two connection ports formed on the cover body, and a hollow cavity formed in the cover body. The hollow cavity is used to house the quick-connect plug for air passage, and the connection ports are used to allow the pipes connected to the quick-connect plug to pass through.

[0032] In this embodiment, the protective cover includes a first cover 11 and a second cover 12. The first cover 11 and the second cover 12 are detachably connected together and are usually rectangular in shape. After the first cover 11 and the second cover 12 are assembled, the hollow cavity is formed inside.

[0033] The connection ports are set to three, namely the first connection port 21, the second connection port 22 and the third connection port 23. The first connection port 21 and the second connection port 22 are respectively located at the horizontal ends of the first cover 11, and the third connection port 23 is located on the outside of the second cover 12. The three connection ports form a T-shape. This design can meet the shape requirements of most pneumatic quick-connect plugs. Common pneumatic quick-connect plugs include T-shaped, straight, and right-angle shapes.

[0034] The suction mechanism 2 is connected to the hollow chamber inside the protective cover 1 through a dedicated pipeline, and is used to extract the gas inside the hollow chamber. In this embodiment, a peristaltic pump can be used, and in other embodiments, other conventional air pumps can also be used.

[0035] The gas detector is connected to the outlet end of the suction mechanism to detect the extracted gas. The type and model of the gas detector can be determined according to the specific composition of the gas path being tested.

[0036] The waste gas treatment equipment is connected to the outlet of the gas detector to purify the gas. It usually adopts adsorption treatment and is designed with a multi-layer filtration structure, using common adsorbents such as activated carbon.

[0037] Working principle explanation:

[0038] The protective cover completely encloses the quick-connect gas connector to be tested. When the test is started and gas passes through the pipes inside the quick-connect gas connector, the suction mechanism draws the airflow from the protective cover to the gas detector for testing. If a gas leak is detected, the gas detector can identify the gas and determine that the quick-connect connector is leaking, and then notify the staff to replace it in time.

[0039] This device is typically used in two scenarios:

[0040] One function is for pre-use inspection of the equipment. The first cover 11 and the second cover 12 are opened, the quick-connect fitting is placed into the hollow cavity, and then the cover is closed. At the same time as starting the test, the suction mechanism and gas detector are started, and the detection time is set to realize the pre-use inspection of the equipment. The second function is for monitoring during the use of the experimental equipment. During the use of the experimental equipment, the early warning device operates synchronously and continuously monitors the quick-connect fitting. If a leak occurs, it can be detected in time.

[0041] Because toxic gases are harmful, although they are difficult to diffuse into the environment under negative pressure, in order to improve safety, ensure the sealing of the connection ports, and prevent harmful gases from leaking to the outside of the protective cover, in a preferred embodiment, each of the connection ports is provided with a flexible sealing structure and a sealing cover. The flexible sealing structure generally includes a flexible sealing ring, etc., which is wrapped around the outside of the gas path to achieve a seal; the sealing cover is mainly used to close the connection port. When the quick-connect plug of the gas path has only two ends, the connection port of the third end needs to be closed, which can be done by using the sealing cover.

[0042] In two preferred embodiments, a bypass can be provided for the dedicated pipeline connecting the other suction mechanisms and the hollow cavity of the protective cover in a synchronous and intermittent manner. The bypass and the dedicated pipeline switch flow directions through a three-way valve.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
