[0026] To make the objectives, technical solutions and advantages of the present utility model clearer, exemplary embodiments of the present utility model will be described below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. For the sake of clarity and conciseness, not all features of the actual implementation manners are described in the specification.

[0027] Here, it should also be noted that in order to avoid obscuring the present utility model with unnecessary details, only the device structures and / or processing steps closely related to the solutions according to the present utility model are shown in the drawings, while other details less relevant to the present utility model are omitted.

[0028] Embodiments of the present utility model provide a twin outdoor foldable smog chamber, which can be quickly transferred to the experimental area and directly introduce real atmosphere for synchronous simulation research. Specifically, as Figure 1As shown in the figure, the twin outdoor foldable smog chamber includes: a support frame 10 and two identical and independent chambers. Among them, the two chambers are used to conduct atmospheric reaction experiments synchronously; the chambers are detachably supported on the support frame 10, and the two chambers are arranged side by side in parallel on the support frame 10; the chambers are arranged in a foldable structure. When the chambers are supported on the support frame 10, the chambers are in an unfolded state; when the chambers are detached from the support frame 10, the chambers can be folded into a folded state.

[0029] The smog chamber of the present utility model overcomes the limitations of traditional smog chambers. By adopting detachable and foldable twin chambers, it combines portability, foldability and the ability to conduct synchronous simulation experiments, facilitating research on atmospheric photochemical reactions and pollutant changes in different outdoor environments, and enabling flexible and efficient atmospheric environment monitoring and simulation.

[0030] In some embodiments, as Figure 1 shown, the chamber includes a Teflon film cylinder 20 and a flange 30. Openings are formed at both ends of the Teflon film cylinder 20, and the flange 30 is sealingly connected to the openings of the Teflon film cylinder 20. By setting the transparent and flexible Teflon film cylinder 20 in this embodiment, it is convenient to monitor and simulate pollutant changes and photochemical reactions in outdoor atmosphere under light conditions, and it is light and durable. At the same time, the chamber can be folded, facilitating the storage, carrying and transfer of the chamber when not in use.

[0031] Moreover, in this embodiment, the flange 30 is circular, and the Teflon film cylinder 20 is fixedly connected between the two flanges 30, thus forming a cylindrical chamber. The structural design is simple, without the need to set up a complex support structure to support the Teflon film cylinder 20. Only by the flanges 30 at both ends can it be connected to the Teflon film cylinder 20 to form a cylindrical chamber, creating an accommodation space inside, and facilitating the folding and storage of the chamber at the same time. When not in use, overlap the flanges 30 at both ends and fold the Teflon film cylinder 20 to make it in a folded state, then the storage of the chamber can be realized, and the operation is convenient; when in use, unfold the Teflon film cylinder 20 and support the chamber on the support frame 10, then it can be kept in an unfolded state for experiments.

[0032] In some embodiments, the flange 30 can be a polytetrafluoroethylene flange, and the two ends of the Teflon film cylinder 20 are welded to the flange 30 to achieve their fixed connection and sealing.

[0033] As Figure 3 shown, in some embodiments, the flange 30 includes a first flange plate 31 and a second flange plate 32. One end of the Teflon film cylinder 20 is welded to one side of the first flange plate 31, and a circular groove is formed on the other side of the first flange plate 31. The second flange plate 32 is in a disc shape and is sealingly inlaid in the groove.

[0034] In some embodiments, the flange 30 is provided with a gas inlet and outlet, thereby providing a channel for gas to enter the box, so as to introduce the real atmosphere in the experimental environment into the box for monitoring and experimental research.

[0035] Specifically, the first flange 31 is annular, and a through hole is formed at the center thereof. The size of the through hole is smaller than that of the second flange 32. The second flange 32 is used to seal the through hole. At the same time, a gas inlet and outlet are provided on the second flange 32. The gas inlet and outlet are connected to the through hole of the first flange 31. The gas pipeline can be connected to the gas inlet and outlet, so as to realize the gas inlet and outlet of the box. Figure 1 As shown, the gas outlet and the gas inlet are respectively arranged at two flanges 30 at both ends of the box body.

[0036] In some embodiments, the gas outlet may be connected to a gas delivery device through a pipeline, and the gas delivery device is used to control the gas outside the box to enter the box through the gas inlet and flow to the gas outlet. Specifically, the gas delivery device may be an air pump, a fan, etc.

[0037] like Figure 2 As shown, in some embodiments, the support frame 10 has a plurality of support rods 11, and the plurality of support rods 11 are detachably connected and assembled to form the support frame 10. The support frame 10 of this embodiment is easy to assemble and disassemble, and is convenient to carry, transport and store. When in use, the support rods 11 can be assembled and used. At the same time, a foldable box is used, so that the user can quickly set up the experimental environment at different research locations.

[0038] In some embodiments, a portion of the multiple support rods 11 are connected to form a support platform, which is placed parallel to the ground or other plane to ensure the overall stability of the support frame 10; another portion of the support rods 11 are vertically connected to the support platform to facilitate connection with the box to provide support for the box.

[0039] Specifically, Figure 2 As shown, the support frame 10 includes 10 support rods 11, wherein 4 support rods 11 are connected and assembled to form a rectangular frame, and the rectangular frame is placed parallel to the ground or other planes; the other 6 support rods 11 are vertically connected to the rectangular frame to form a support frame 10 with a rectangular frame structure. Among them, 4 support rods 11 are vertically connected to the four corners of the rectangular frame, and the other 2 support rods 11 are vertically connected to the middle of the two opposite sides of the rectangular frame, so that the two sides of the two boxes are supported by the 6 support rods.

[0040] In some embodiments, a connecting member is fixed to the outer surface of the box body. The connecting member is detachably connected to the support frame 10, thereby realizing the installation of the box body on the support frame 10. The support frame 10 is matched with the box body in the unfolded state, so that the box body can be extended and supported on the support frame 10 for atmospheric monitoring and experiments.

[0041] Among them, the connecting member can be a connecting strap. For example, a Teflon film strap is welded to the outer surface of the box body. When installing the box body on the support frame 10, since the box body is light, by bundling the connecting strap on the support frame 10, the assembly of the two can be realized, and the connection structure is simple and the operation is convenient.

[0042] Specifically, as Figure 1 shown, a plurality of connecting straps 21 are symmetrically fixed to both sides of the Teflon film cylinder 20 respectively. The connecting straps 21 are bundled on the vertically arranged support rod 11, thereby realizing the installation and fixation of the two box bodies.

[0043] As Figure 1 shown, the smog chamber further includes a light-shielding component 40. The light-shielding component 40 can selectively cover the surface of the box body. When the light-shielding component 40 covers the surface of one of the box bodies, the two box bodies are used for comparative experiments under light-shielding and illumination conditions simultaneously; when the light-shielding component 40 covers the surfaces of both box bodies at the same time, the two box bodies are used for parallel experiments under light-shielding conditions; when the light-shielding component 40 does not cover the surface of any box body, the two box bodies are used for parallel experiments under illumination conditions.

[0044] The utility model can simultaneously conduct parallel experiments on atmospheric photochemical reactions and pollutant concentration changes under light-shielding conditions or illumination conditions by controlling whether the light-shielding component 40 covers both box bodies at the same time, ensuring the reliability of the experiments; by controlling the light-shielding component 40 to cover one of the box bodies, comparative experiments on atmospheric photochemical reactions and pollutant concentration changes can be conducted simultaneously under two different environmental conditions of illumination and light-shielding conditions.

[0045] In some embodiments, the light-shielding component 40 includes a light-shielding layer and a connecting rope fixed to the light-shielding layer. By manually manipulating the connecting rope, the light-shielding layer can be controlled to cover one or two box bodies.

[0046] In some embodiments, an environmental monitoring sensor (not shown in the figure) is installed on the flange 30 provided with a gas outlet, and the environmental monitoring sensor is installed inside the box body, and the flange 30 provides support for the environmental monitoring sensor. By installing the environmental monitoring sensor, the utility model can monitor the atmospheric conditions inside the box body in real time, providing data for monitoring and simulating atmospheric photochemical reactions and pollutant concentration changes.

[0047] Among them, the environmental monitoring sensors include at least one of a temperature sensor, a humidity sensor, a light sensor, and a gas composition analysis sensor, which are respectively used to monitor the temperature, humidity, light intensity in the box, and the concentration change of the target component in the gas.

[0048] In addition, at least one interface is also provided on the flange 30. The transmission line of the environmental monitoring sensor extends outside the box through the interface and is connected to the data acquisition and data processing device to realize the real-time monitoring of the gas composition and the concentration of the target component in the box.

[0049] The simple twin outdoor folding smog chamber provided by the utility model simplifies the structural complexity and operation difficulty of the traditional smog chamber. Its structural design is simple and intuitive, and the operation is convenient. It can be quickly built and disassembled during use, and is convenient for storage and collection. At the same time, it maintains its function in atmospheric environment monitoring and simulation, enabling users to conduct effective atmospheric simulation research even under limited resources. It is especially suitable for the research of pollutant sampling, photochemical reaction, and pollutant change in the outdoor environment. Especially in the case where rapid deployment and movement are required, it can conduct efficient atmospheric simulation experiments in various outdoor environments, providing a scientific basis for air pollution prevention and control.

[0050] When using the smog chamber of the utility model for atmospheric monitoring experiments, the operation steps specifically include:

[0051] Step S1, assemble the support frame 10, and unfold and connect the two boxes of the smog chamber to the support frame 10;

[0052] Step S2, control the gas to enter each box from the gas inlet of each box and flow to the gas outlet;

[0053] Step S3, real-time monitor the target component and its concentration in the gas at the gas outlet of each box;

[0054] Step S4, after the monitoring is completed, remove the box from the support frame 10, fold and store it, and disassemble the support frame 10.

[0055] When controlling the light-shielding component 40 to completely cover the two boxes or when neither of the two boxes is covered by the light-shielding component, real-time monitor the target component and its concentration in the gas in each box under light-shielded conditions or light conditions to conduct a parallel comparison experiment.

[0056] Specifically, when conducting parallel comparison experiments under light-shielding conditions, the light-shielding component 40 completely covers the two boxes, and dark rooms are formed inside the two boxes. Control the atmosphere in the environment to flow from the gas inlets of each box to the gas outlets respectively. The environmental monitoring sensors located at the gas outlets collect gas samples and conduct detections to perform real-time detection of the target components and their concentrations in the atmospheric environment, and analyze the concentration changes of the target components in the atmospheric environment under light-shielding conditions according to the detection results.

[0057] When conducting parallel comparison experiments under light conditions, there is no need to operate the light-shielding component 40, and the two boxes are both exposed to light, and bright rooms are formed inside the boxes. Control the atmosphere in the environment to flow from the gas inlets of each box to the gas outlets respectively. The environmental monitoring sensors located at the gas outlets collect gas samples and conduct detections to perform real-time detection of the target components and their concentrations in the atmospheric environment, and analyze the concentration changes of the target components in the atmospheric environment and the photochemical reactions that occur according to the detection results.

[0058] When the light-shielding component 40 covers the surface of one of the two boxes, the target components and their concentrations of the gas in the box are monitored in real time under light-shielding conditions and light conditions; and according to the target components and their concentrations under light-shielding conditions and light conditions, the concentration changes of the gas before and after the photochemical reaction are compared.

[0059] Specifically, when conducting comparison experiments under light conditions and light-shielding conditions, the light-shielding component 40 covers the surface of one of the boxes, so that bright rooms and dark rooms are respectively formed inside the two boxes. For the light-shielded box, no photochemical reaction occurs during the period when the gas flows from the gas inlet of the box to the gas outlet. The target components and their concentrations in the gas at the outlet are monitored in real time by the environmental monitoring sensors at the outlet; for the box under light, photochemical reactions occur during the period when the gas flows from the gas inlet of the box to the gas outlet. The target components and their concentrations in the gas at the outlet are monitored in real time by the environmental monitoring sensors at the outlet. By comparing the target components and their concentrations in the gas at the outlets of the two boxes, the concentration changes of the target components in the atmosphere before and after the photochemical reaction can be compared and analyzed.

[0060] As described above, it is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
