[0061] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0062] The following is for reference. Figures 1-25 The test apparatus 100 according to an embodiment of the present invention is described.

[0063] like Figure 1 , Figure 6 and Figure 7 As shown, the testing device 100 according to an embodiment of the present invention is used to test the processing effect of the gas processing device 200, and includes: a housing 1, a gas collection device 2, and a detection device 3.

[0064] Specifically, the testing device 100 is used to test the treatment effect of the gas treatment device 200. The outer casing 1 has a circulation channel 14 and an inlet 15 and an outlet 16 connected to the circulation channel 14. The circulation channel 14 has a treatment area 18, in which the gas treatment device 200 is disposed. The gas collection device 2 is connected to the outer casing 1 and has a collection chamber connected to the circulation channel 14 through the inlet 15. The detection device 3 is connected to the outer casing 1 and has a detection chamber connected to the circulation channel 14 through the outlet 16. It can be understood that the testing device 100 creates a closed circulation system to simulate actual working conditions, thereby accurately measuring the changes in gas composition before and after treatment, and thus judging and quantifying the treatment effect of the gas treatment device 200.

[0065] Reference Figure 6 and Figure 7 As shown, the outer casing 1 forms the basic frame of the testing device 100. A circulation channel 14 is formed within the outer casing 1, guiding gas to circulate within it. The inlet 15 and outlet 16 are connected to and communicate with the circulation channel 14. The inlet 15 serves as the entrance for untreated gas into the circulation channel 14, and the outlet 16 serves as the exit for treated gas leaving the circulation channel 14. A processing zone 18 is part of the circulation channel 14 and is located within it. The processing zone 18 is suitable for placing the gas processing device 200 to be tested. A processing channel is formed within the gas processing device 200, extending along the airflow direction. Both ends of the processing channel are connected to the circulation channel. Channel 14 is connected, and gas enters the gas treatment device 200 through the treatment channel for gas treatment. Gas collection device 2 is connected to the outer shell 1 and has a collection chamber. The collection chamber is connected to the circulation channel 14 through the air inlet 15. The gas collection device 2 collects raw gas samples for introducing a certain amount of untreated gas samples into the circulation channel 14 at the beginning of the test. Detection device 3 is connected to the outer shell 1 and has a detection chamber. The detection chamber is connected to the circulation channel 14 through the air outlet 16. The treated gas enters the detection device 3 through the air outlet 16 for gas analysis to determine the change in pollutant concentration and thus evaluate the effect of the gas treatment device 200.

[0066] Before starting the test, it is necessary to ensure that there are no residual pollutants in the circulation channel 14. The gas processing device 200 is placed in the processing area 18, and the outer casing 1 is sealed to reduce the influence of external factors on the test results. Then, the gas sample containing odor pollutants is collected from the test environment by the gas collection device 2 or a sample of odor gas with a specific concentration is prepared in advance. The sample gas is introduced into the circulation channel 14. After being processed by the gas processing device 200, the sample gas reaches the detection device 3, which analyzes its composition or concentration to determine the effectiveness of the gas processing device 200.

[0067] According to the test device 100 of this utility model embodiment, by comparing the difference between the original sample collected by the gas collection device 2 and the processed sample obtained by the detection device 3, the working efficiency of the gas processing device 200 is quantitatively evaluated, realizing a rapid and accurate evaluation of the processing effect of the gas processing device 200 under the condition of unique variables, thereby improving the accuracy of the test results.

[0068] In some embodiments of this utility model, switching valves are provided at both the air inlet 15 and the air outlet 16 to control the connection and disconnection between the collection chamber and the circulation channel 14, as well as between the detection chamber and the circulation channel 14. It is understood that the switching valves can open or close the corresponding airflow passages. For example, the switching valve at the air inlet 15 can open or close the airflow passage between the gas collection device 2 and the circulation channel 14, and the switching valve at the air outlet 16 can open or close the airflow passage between the gas collection device 2 and the circulation channel 14. The switching valve at the air inlet 15 allows or prevents gas from entering the circulation channel 14, and the switching valve at the air outlet 16 allows or prevents gas from leaving the circulation channel 14. By closing the switching valves at the air inlet 15 and the air outlet 16, the circulation channel 14 can be completely sealed during testing to prevent external air from mixing in and maintain the stability and purity of the internal environment.

[0069] Before starting the test, it is necessary to ensure that there are no residual pollutants in the circulation channel 14. Place the gas processing device 200 in the processing area 18 and ensure that the outer shell 1 is sealed to reduce the influence of external factors on the test results. Then, collect gas samples containing odor pollutants from the test environment through the gas collection device 2 or prepare odor gas samples with a specific concentration in advance. Open the switch valve at the air inlet 15 to introduce the sample gas into the circulation channel 14. After the sample gas is introduced, close the switch valve at the air inlet 15. After the sample gas is processed by the gas processing device 200, open the switch valve at the air outlet 16 to allow the sample gas to reach the detection device 3. The detection device 3 analyzes its composition or concentration to determine the effectiveness of the gas processing device 200.

[0070] In other embodiments, the switching valve can also be used to adjust the gas flow rate to suit different types of testing needs.

[0071] In some embodiments of this utility model, the testing device 100 further includes a heating element 7, which is disposed within the circulation channel 14 to heat the gas within the circulation channel 14, such as... Figure 6 and Figure 11 As shown. It is understood that the heating element 7 is disposed within the circulation channel 14 to heat the gas therein. When it is necessary to simulate the gas treatment effect under different temperature conditions or under constant temperature conditions, it not only expands the application range of the test device 100, but also allows researchers to more accurately evaluate the performance of the gas treatment device 200 at various temperatures. The heating element 7 is mainly used to maintain or adjust specific temperature conditions within the circulation channel 14. Alternatively, in some cases, appropriately increasing the temperature can accelerate the reaction rate, thereby shortening the test cycle. Or, within the optimal operating temperature range of the gas treatment device 200, the highest activity and stability of the reactants or adsorbates within the gas treatment device 200 can be exhibited.

[0072] In other words, the heating element 7 ensures a constant temperature within the circulation channel 14, or the heating element 7 can simulate the gas treatment effect under different temperature conditions, or the temperature can be increased to accelerate the processing rate and shorten the test cycle.

[0073] Before introducing the untreated gas sample, the heating element 7 is activated to bring the circulation channel 14 to the set initial temperature (which can be room temperature or the desired target temperature). Once the target temperature is reached, the heating element 7 is turned off or its power is maintained at the current value to ensure that the temperature fluctuates within a narrow range and does not affect the experimental results. If it is necessary to test the performance of the gas processing device 200 under different temperature conditions, the output power of the heating element 7 can be gradually adjusted during the test to achieve temperature gradient changes. After sufficient data collection at each temperature point, the test continues at the next temperature point to ensure that there is enough data for analysis under each condition.

[0074] In some embodiments of this utility model, the circulation channel 14 has a receiving area 17, the heating element 7 is disposed in the receiving area 17, and the receiving area 17 is also provided with a driving element 6, which is used to drive the airflow within the circulation channel 14, such as... Figure 6 and Figure 11 As shown. It can be understood that the receiving area 17 provides installation space for the heating element 7 and the driving element 6, ensuring precise control of the temperature and flow rate of the airflow in the circulation channel 14. The driving element 6 is used to drive the airflow in the circulation channel 14, ensuring sufficient mixing of the gas in the processing area 18 and effective contact with the processing device.

[0075] In other embodiments, the drive unit 6 ensures that the gas flow velocity within the circulation channel 14 remains consistent. Alternatively, the drive unit 6 can also adjust the gas flow within the circulation channel 14 to a target flow velocity desired by the user. This can be used to control the effect of gas flow velocity on the processing effect of the gas treatment module (given a specific temperature Ts, a specific initial concentration C0, and a specific isothermal operating time t, the power of the drive unit 6 is changed to regulate the gas flow velocity, and an anemometer is installed before the gas enters the processing zone 18).

[0076] In some embodiments of this utility model, such as Figure 6 As shown, the cross-sectional area of ​​the containment zone 17 is larger than that of the circulation channel 14. Understandably, the larger cross-sectional area of ​​the containment zone 17 provides more physical space, allowing for a more rational arrangement of the heating element 7 and the driving element 6, reducing interference between them. The larger cross-sectional area also facilitates pre-treatment of the gas flow before it enters the processing zone 18, such as through heating or preliminary mixing, ensuring more stable and uniform gas conditions entering the processing zone 18. Within the containment zone 17, the increased cross-sectional area leads to a corresponding decrease in airflow velocity, extending the residence time of the gas within the containment zone 17. The lower flow velocity helps improve the heat exchange efficiency between the gas and the heating element 7, ensuring the gas is sufficiently heated to the required temperature. The larger cross-sectional area reduces the resistance encountered by the driving element 6 when propelling the airflow, allowing the driving element 6 to maintain the necessary airflow velocity with lower energy consumption. This promotes smooth flow and effective mixing of the airflow within the circulation channel 14, improves heating efficiency, and enhances the reliability and accuracy of experimental data.

[0077] In some embodiments of this utility model, such as Figure 6 As shown, the two ends of the receiving area 17 are connected to a first connecting segment 171 and a second connecting segment 172, respectively. The cross-sectional area of ​​the first connecting segment 171 gradually decreases in the direction away from the receiving area 17, and the cross-sectional area of ​​the second connecting segment 172 also gradually decreases in the direction away from the receiving area 17. It can be understood that one end of the receiving area 17 is connected to the first connecting segment 171, and the other end is connected to the second connecting segment 172. The cross-sectional area of ​​the first connecting segment 171 gradually decreases in the direction away from the receiving area 17, meaning the cross-sectional area of ​​the portion of the first connecting segment 171 closest to the receiving area 17 is larger than the cross-sectional area of ​​the portion of the first connecting segment 171 furthest from the receiving area 17. Similarly, the cross-sectional area of ​​the second connecting segment 172 gradually decreases in the direction away from the receiving area 17, meaning the cross-sectional area of ​​the portion of the second connecting segment 172 closest to the receiving area 17 is larger than the cross-sectional area of ​​the portion of the second connecting segment 172 furthest from the receiving area 17. This not only promotes smooth airflow and effective mixing but also improves heating efficiency and enhances the reliability and accuracy of experimental data.

[0078] In some embodiments of this utility model, such as Figure 1 As shown, the outer casing 1 includes a first shell 11, a second shell 12, and a third shell 13 connected end to end in sequence. A first connecting segment 171 is formed at the end where the first shell 11 connects to the second shell 12. A receiving area 17 is formed inside the second shell 12. A second connecting segment 172 is formed at the end where the third shell 13 connects to the second shell 12. It can be understood that the outer casing 1 includes a first shell 11, a second shell 12, and a third shell 13, which are connected end to end in sequence. That is, the two ends of the first shell 11 are respectively connected to the second shell 12 and the third shell 13, the two ends of the second shell 12 are respectively connected to the first shell 11 and the third shell 13, and the two ends of the third shell 13 are respectively connected to the second shell 12 and the third shell 13. A circulation channel 14 passes through the first shell 11, the second shell 12, and the third shell 13. As shown in the figure, the air inlet 15 and the air outlet 16 are both formed on the first housing 11, and the receiving area 17 is formed inside the second housing 12. The heating element 7 and the driving element 6 are both disposed in the receiving area 17 inside the second housing 12. Thus, the segmented housing 1 allows each part to be manufactured and disassembled independently, reducing the complexity of production and maintenance, improving the structural flexibility of the testing device 100, and facilitating disassembly and maintenance.

[0079] In some embodiments of this utility model, such as Figure 19 and Figure 20 As shown, both ends of the first housing 11 are formed with first flanges 111, as... Figure 14 and Figure 15 As shown, both ends of the second housing 12 are formed with second flanges 121, such as... Figure 17 and Figure 18 As shown, both ends of the third housing 13 have third flanges 131. The first housing 11 and the second housing 12 are connected by the first flange 111 and the second flange 121, the second housing 12 and the third housing 13 are connected by the second flange 121 and the third flange 131, and the third housing 13 and the first housing 11 are connected by the third flange 131 and the first flange 111. It can be understood that the flanges at both ends of the first housing 11, the second housing 12, and the third housing 13 increase the contact area between the housings 1, improve the structural strength of the testing device 100, and provide installation positions for the seals, thereby effectively preventing gas leakage within the circulation channel 14.

[0080] Optionally, the first housing 11 and the second housing 12 can be connected by fasteners passing through the first flange 111 and the second flange 121. Alternatively, the first housing 11 and the second housing 12 can be connected by welding the first flange 111 and the second flange 121. The connection methods of the first housing 11 and the second housing 12 include the two methods mentioned above, but are not limited to them. The second housing 12 and the third housing 13 can be connected by fasteners passing through the second flange 121 and the third flange 131. Alternatively, the second housing 12 and the third housing 13 can be connected by welding the second flange 121 and the third flange 131. The connection methods of the second housing 12 and the third housing 13 include the two methods mentioned above, but are not limited to them. The third housing 13 and the first housing 11 can be connected by fasteners passing through the third flange 131 and the first flange 111. Alternatively, the third housing 13 and the first housing 11 can be connected by welding the third flange 131 and the first flange 111. The connection methods of the third housing 13 and the first housing 11 include the two methods mentioned above, but are not limited to them.

[0081] Furthermore, a sealing ring is provided between the first flange 111 and the second flange 121 to seal between the first housing 11 and the second housing 12, thereby improving the sealing performance between the first housing 11 and the second housing 12. A sealing ring is provided between the second flange 121 and the third flange 131 to seal between the second housing 12 and the third housing 13, thereby improving the sealing performance between the second housing 12 and the third housing 13. A sealing ring is provided between the third flange 131 and the first flange 111 to seal between the third housing 13 and the first housing 11, thereby improving the sealing performance between the third housing 13 and the first housing 11.

[0082] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, a temperature measuring element 4 is provided in the processing zone 18. The temperature measuring element 4 is used to measure the temperature of the gas flowing through the processing zone 18. It can be understood that setting the temperature measuring element 4 in the processing zone 18 to measure the temperature of the gas flowing through the gas processing device 200 helps to monitor the temperature changes in the processing zone 18 in real time and ensure that the set temperature conditions are maintained throughout the experiment.

[0083] In some embodiments of this utility model, such as Figure 9As shown, the processing area 18 has an opening 181 that communicates with the processing area 18. A cover 19 is provided at the location of the opening 181, and the cover 19 is detachably positioned over the opening 181. It is understood that the opening 181 in the processing area 18 facilitates quick assembly or disassembly of the gas processing device 200 by the user. During assembly or disassembly, it is not necessary to disassemble the entire testing device 100; the gas processing device 200 can be assembled or disassembled from the opening 181. This saves the user's testing time and effort and facilitates cleaning of the processing area 18. The cover 19 is used to seal the opening 181 and, together with the first housing 11, defines the circulation channel 14.

[0084] Furthermore, a seal is provided between the cover plate 19 and the opening 181 to prevent gas leakage and maintain stable pressure and temperature conditions within the circulation channel 14.

[0085] Furthermore, a locking element is provided between the cover plate 19 and the opening 181 to prevent the cover plate 19 from being opened or loosened accidentally, thus ensuring the stability and reliability of the testing device 100 and ensuring the accuracy of the test results.

[0086] In some embodiments of this utility model, such as Figure 9 As shown, a bracket 5 is provided in the processing area 18. The bracket 5 is snap-fitted to the gas processing device 200. This simplifies the installation and disassembly of the gas processing device 200, providing greater flexibility and convenience for test operations. The bracket 5 ensures the stability and reliability of the gas processing device 200 during the test process. The snap-fit ​​connection allows the gas processing device 200 to be easily removed and placed, facilitating regular maintenance, inspection, or cleaning, and reducing equipment downtime.

[0087] Optionally, the bracket 5 can be connected to the first housing 11 by fasteners, or the bracket 5 can be connected to the first housing 11 by welding. The connection methods between the bracket 5 and the first housing 11 include, but are not limited to, these.

[0088] In some embodiments of this utility model, such as Figure 10 As shown, the second housing 12 has a first through hole 122, which is used to install the heating element 7, such as... Figure 17As shown, the third housing 13 has a second through hole 132 for mounting the drive shaft 61 of the drive component 6. It is understood that the first through hole 122 ensures the correct installation and use of the heating element 7 and facilitates its disassembly and assembly. Here, the heating element 7 can be securely installed into the first through hole 122 via threaded connection, flange, or other mechanical fixing methods. The second through hole 132 ensures the correct installation and use of the drive component 6 and facilitates its disassembly. Since the drive shaft 61 of the drive component 6 may cause gas leakage during rotation, a dynamic seal (e.g., an oil seal) is provided around the second through hole 132 to improve airtightness while allowing the drive shaft 61 to rotate freely. A drive shaft 61 bearing is installed at the position of the second through hole 132 to support the drive shaft 61 of the drive component 6 and reduce friction. This improves the reliability and accuracy of the experimental data.

[0089] In some embodiments of this utility model, the outer peripheral surface of the housing 1 is provided with a heat insulation layer. The heat insulation layer not only helps to maintain the temperature stability in the circulation channel 14 and reduce heat loss, thereby reducing the workload of the heating element 7, improving energy utilization efficiency, and ensuring the consistency of test conditions, but also protects the external environment and operators from the effects of high temperature, improving operational safety. Furthermore, the heat insulation layer also reduces the noise generated by gas flow in the test device 100.

[0090] Alternatively, the insulation layer may be an aerogel coating, a nano-ceramic coating, a silicate coating, a polyurethane insulation coating, a vacuum glass microsphere insulation coating, etc.

[0091] To ensure good thermal insulation performance, the thickness of the insulation layer should be 3mm-8mm. Specifically, the thickness of the insulation layer can be any value between 3mm and 8mm, for example, the thickness of the insulation layer can be 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, 5.2mm, 5.4mm, 5.6mm, 5.8mm, 6mm, 6.2mm, 6.4mm, 6.6mm, 6.8mm, 7mm, 7.2mm, 7.4mm, 7.6mm, 7.8mm, 8mm, etc.

[0092] In some embodiments of this utility model, the testing device 100 further includes a control module, which is electrically connected to the drive component 6, the heating component 7, and the temperature measuring component 4. It is understood that the control module, as the core controller, can centrally manage and coordinate the operation of the drive component 6, the heating component 7, and the temperature measuring component 4, ensuring coordinated operation among the components. The control module can collect parameter data from the temperature measuring component 4 and anemometers, and send electrical signals to the heating component 7 and the drive component 6, thereby starting or stopping the heating component 7 or the drive component 6, reducing the need for manual operation and improving testing efficiency.

[0093] In some embodiments of this invention, the detection device 3 includes a detection module electrically connected to a control module. The detection module transmits the detection results and data of the sample gas to the control module. Based on the real-time data provided by the detection module, the control module dynamically adjusts the power of the heating element 7 and the speed of the driving element 6 to ensure the consistency and stability of experimental conditions. Furthermore, based on feedback from the detection module, the control module can automatically optimize experimental parameters, finding the most suitable temperature, airflow speed, and other conditions to improve experimental efficiency and the reliability of results.

[0094] In some embodiments of this invention, the testing device 100 further includes an analysis module, which is electrically connected to both the detection module and the control module. It is understood that the analysis module can receive data streams from the detection module in real time, perform rapid processing and analysis, provide immediate feedback, and employ advanced data analysis algorithms, such as machine learning or statistical models, to extract valuable information from large amounts of data, helping researchers better understand the test results of the gas processing device 200. Furthermore, the analysis module can simultaneously process multiple parameters (such as temperature, airflow velocity, gas composition, etc.) and identify the correlations and potential patterns between them.

[0095] In some embodiments of this utility model, the testing device 100 further includes a display module, which is electrically connected to both the control module and the analysis module. That is, the display module can display key parameters such as temperature, airflow velocity, and gas composition from the detection module in real time, providing comprehensive monitoring information. The display module can generate real-time updated charts and trend graphs to intuitively display parameter changes, thereby determining the test results of the gas processing device 200.

[0096] Optionally, the outer casing 1 is formed of metal, which has high mechanical strength and can withstand large pressure and temperature changes, ensuring the equipment remains stable in any environment; the drive component 6 is an axial fan, which has low noise, small size, and high energy efficiency; the temperature measuring component 4 is a thermocouple wire, which can provide accurate temperature measurement over a wide temperature range and has a fast temperature response speed. Thus, the testing stability and reliability of the testing device 100 are ensured.

[0097] The following will refer to Figures 1-25 A test apparatus 100 according to a specific embodiment of the present invention is described.

[0098] Reference Figures 1-25 The testing device 100 includes a housing 1, a gas collection device 2, a detection device 3, a heating element 7, a driving element 6, and a temperature measuring element 4.

[0099] Specifically, a circulation channel 14 is formed inside the outer casing 1, and a heat insulation layer is provided on the outer peripheral wall of the outer casing 1. The outer casing 1 has a circulation channel 14 and an air inlet 15 and an air outlet 16 connected to the circulation channel 14. Switch valves are provided at the positions of the air inlet 15 and the air outlet 16. The circulation channel 14 has a processing area 18 and a receiving area 17. The heating element 7 and the driving element 6 are located in the receiving area 17. The temperature measuring element 4, the bracket 5 and the gas processing device 200 are all located in the processing area 18. The bracket 5 is connected to the outer casing 1, and the gas processing device 200 is located on the bracket 5. The processing area 18 has an opening 181, and a cover plate 19 is provided at the position of the opening 181. The cover plate 19 is detachably placed at the position of the opening 181. The outer casing 1 includes a first casing 11, a second casing 12, and a third casing 13, which are connected sequentially end-to-end. Specifically, the two ends of the first casing 11 are connected to the second casing 12 and the third casing 13, the two ends of the second casing 12 are connected to the first casing 11 and the third casing 13, and the two ends of the third casing 13 are connected to the second casing 12 and the third casing 13, respectively. A circulation channel 14 extends through the first casing 11, the second casing 12, and the third casing 13. Each end of the first casing 11, the second casing 12, and the third casing 13 has a flange, which increases the contact area between the connections of the outer casing 1 and improves the structural strength of the testing device 100.

[0100] Before starting the test, it is necessary to ensure that there are no residual pollutants in the circulation channel 14. The gas treatment device 200 is placed in the treatment area 18, and the outer shell 1 is sealed to reduce the influence of external factors on the test results. Then, a gas sample containing odor pollutants is collected from the test environment through the gas collection device 2, or a sample of odor gas with a specific concentration is prepared in advance. The switch valve at the inlet 15 is opened to introduce the sample gas into the circulation channel 14. The temperature of the sample gas and the gas treatment device 200 is controlled at a preset constant temperature by the cooperation of the heating element 7 and the temperature measuring element 4. After the sample gas is introduced, the switch valve at the inlet 15 is closed. After the sample gas is processed by the gas treatment device 200, the switch valve at the outlet 16 is opened and the sample gas reaches the detection device 3. The detection device 3 analyzes its composition or concentration and compares the concentration of pollutants in the sample gas with the concentration of pollutants in the sample gas before treatment to determine the effect of the gas treatment device 200. Finally, the calculated treatment effect is output in the form of quantitative data.

[0101] Specifically, the gas collection device 2 contains initial odor gas with a target concentration. The inlet valve 15 is opened, and the axial fan is turned on (with the target voltage set to maintain the target speed), driving the odor gas to circulate within the circulation channel 14 of the entire testing device 100. After a certain period, the circulation channel 14 is filled with the initial concentration of odor gas, and the inlet valve 15 is closed. The heating element 7 is turned on, and the target power is set to rapidly heat the gas in the circulation channel 14. After a certain period, under the continuous driving circulation of the axial fan, the gas in the pipe is heated to the target temperature Ts (monitored by the thermocouple wire), and then this constant temperature is maintained. Subsequently, the outlet valve 16 is opened, and the initial concentration of odor gas pollutants C0 (T = Ts) is measured by the detection device 3, the data is recorded, and the outlet valve 16 is closed. Subsequently, quickly open the treatment cover 19 (the cover 19 can be installed and fixed to the outer casing 1 by clips or screws), snap the gas treatment device 200 onto the bracket 5, and quickly seal the cover 19 to the open position 181. Then, at the set temperature and the fan speed of the drive shaft 61, drive the odor gas to circulate in the circulation channel 14. After constant temperature operation for a certain time t, open the switch valve of the outlet 16, measure the concentration C1 (T = Ts) of the odor gas pollutants after treatment according to the detection device 3, record the data, and then close the outlet 16 valve. Calculate the treatment effect at temperature Ts based on C1 and C0, and the following calculation method can be used for simple quantitative evaluation:

[0102] η=(C1-C0) / C0

[0103] Example 2,

[0104] At different temperatures, the above-mentioned test device 100 can be used to test the treatment effect of the same gas treatment device 200 at different constant temperatures (during the test, the initial gas pollutant concentration C0 is kept basically the same, the constant temperature operation time t is kept the same, and the voltage and speed of the axial flow fan are kept the same) to study the influence of temperature on the treatment effect of the gas treatment device 200.

[0105] Example 3,

[0106] The aforementioned testing device 100 can also be used to study the change in the treatment effect of the gas treatment device 200 with treatment time (given the target temperature Ts and the initial concentration C0, detect the trend of the treatment effect with time).

[0107] Example 4,

[0108] The aforementioned test device 100 can also be used to study the effect of gas flow rate on the treatment effect of gas treatment device 200 (given target temperature Ts, initial concentration C0, constant temperature operation time t, the gas flow rate is adjusted by changing the voltage of the axial fan motor, and an anemometer is set before the gas enters the treatment zone 18).
