Description

A multifunctional industrial waste gas emission detection device Technical Field

[0001] This utility model relates to the field of exhaust gas emission detection equipment, and in particular to a multifunctional industrial exhaust gas emission detection device. Background Technology

[0002] With the acceleration of industrialization, the problem of waste gas emissions generated during industrial production has become increasingly serious, causing significant environmental pollution. To effectively control and reduce the environmental impact of industrial waste gas emissions, national and local governments have successively introduced a series of stringent environmental protection regulations and standards. Therefore, developing a device capable of accurately and rapidly detecting industrial waste gas emissions is of paramount importance.

[0003] A search revealed Chinese Patent Publication No. CN217212545U, which discloses a multifunctional industrial waste gas emission detection device, relating to the field of waste gas detection technology. The device includes an outer waste gas chamber, inside which a waste gas detection component is installed. One side of the waste gas detection component is connected to a connecting pipe, and one end of the connecting pipe is connected to a waste gas purification component. Opening a first valve and closing a second valve allows waste gas to enter the inner waste gas chamber through the inlet pipe. A control panel controls the waste gas detection probe to detect the waste gas inside the inner chamber. Closing the first valve at this time ensures more stable detection, smaller error in the results, and more accurate detection of waste gas values. If the waste gas fails to meet standards as detected by the waste gas detection component, it enters the waste gas purification pipe. Three activated carbon filter layers filter small particles and toxic substances in the waste gas to meet emission standards. A connecting rod connects the three activated carbon filter layers for easy replacement.

[0004] The aforementioned device has the following drawbacks: when the sensor detects exhaust gas, the gas is partially generated from the outside of the detection tube in the detection chamber, which prevents the sensor from fully contacting the exhaust gas, resulting in incomplete detection results and reducing the accuracy of the equipment in detecting exhaust gas. Therefore, a multifunctional industrial exhaust gas emission detection device is proposed to solve the above problems. Summary of the Invention

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Referring to Figures 1-3, one embodiment of this utility model provides a multifunctional industrial waste gas emission detection device, including a detection box 1. A control panel 2 is detachably connected to the front surface of the detection box 1. The control panel 2 is used by the operator to control the detection device, such as starting, stopping, and setting parameters. It receives signals from the detection sensor 7, processes, displays, and stores the signals, facilitating the operator's real-time understanding of the industrial waste gas emission status and various detection data. An air inlet assembly 3 is provided on the left surface of the detection box 1, and an air outlet pipe 5 is fixedly connected to the right end of the detection box 1. An air outlet valve 4 is provided on the left end of the air outlet pipe 5. The interior of the detection box 1 is equipped with... The system includes an auxiliary component 6. A detection sensor 7 is fixedly installed on the inner wall of the detection box 1. The signal terminal circuit of the detection sensor 7 is connected to the rear surface of the control panel 2. The detection sensor 7 is used to accurately detect the components and concentrations of various pollutants in industrial waste gas, such as sulfur dioxide, nitrogen oxides, and volatile organic compounds. The detection sensor 7 converts the detected waste gas components and concentration information into electrical signals and transmits them to the control panel 2 through its signal terminal circuit. The control panel 2 processes, displays, and stores the data, providing operators with real-time and accurate waste gas emission monitoring data for effective monitoring and management of industrial waste gas emissions.

[0026] Referring to Figures 2-4, the air intake assembly 3 includes a support plate 32, which is fixedly installed on the left surface of the detection box 1. The support plate 32 provides an installation foundation and support platform for the motor 8 and other related components in the air intake assembly 3, ensuring the stability and robustness of the overall structure of the air intake assembly 3. The motor 8 is fixedly installed at the axis on the left surface of the support plate 32. The motor 8 serves as the power source for the air intake assembly 3, driving the rotating column 33 to rotate through its output shaft, thereby driving the fan blades 34 to rotate and the eccentric wheel 35 to work, providing power for the intake of exhaust gas and the oscillation of the air vane 38. Air intake pipes 3 are provided on both the front and rear sides of the left surface of the support plate 32 near the motor 8. 1. The air inlet pipe 31 is used to introduce industrial waste gas into the detection chamber 1. It is the channel for waste gas to enter the detection device. The output shaft of the motor 8 is fixedly connected to the rotating column 33. The right end of the rotating column 33 is fixedly connected to the eccentric wheel 35. As the rotating column 33 rotates, the eccentric wheel 35 generates periodic centrifugal force that acts on the pad 36, thereby affecting the movement of the elastic telescopic rod 37 and the wind vane 38. This allows the wind vane 38 to swing according to the flow of waste gas and the rotation cycle of the eccentric wheel 35, which guides and adjusts the flow direction of the waste gas entering the detection chamber 1, so that the waste gas can be evenly distributed in the detection chamber 1, improving the accuracy and reliability of the detection.

[0027] Referring to Figures 2-4, a fan blade 34 is fixedly connected to the outer wall of the rotating column 33. A fixed frame 39 is fixedly installed on the left surface of the inner wall of the detection box 1. The fixed frame 39 provides support and positioning for the swing of the wind vane 38, while ensuring that the swing of the wind vane 38 can be carried out stably within a predetermined range. An elastic telescopic rod 37 is fixedly connected to the lower surface of the inner wall of the fixed frame 39. The wind vane 38 is sleeved on the outer wall of the elastic telescopic rod 37. When the eccentric wheel 35 rotates and acts on the pad 36, the elastic telescopic rod 37 can extend and retract under the centrifugal force of the eccentric wheel 35, while driving the wind vane 38 to swing around its rotation axis, ensuring that the wind vane 38 can flexibly and stably adjust the flow direction of the exhaust gas to adapt to the entry of exhaust gas with different flow rates and velocities. To ensure uniform distribution of exhaust gas within the detection chamber 1 and create favorable conditions for subsequent testing, the rotating shaft of the wind vane 38 is rotatably connected to the inside of the fixed frame 39. A pad 36 is fixedly connected to the top of the elastic telescopic rod 37, and the outer surface of the pad 36 contacts the outer wall of the eccentric wheel 35. Under the combined action of the elastic telescopic rod 37 and the eccentric wheel 35, the wind vane 38 can swing, thereby guiding and adjusting the flow direction of the industrial exhaust gas entering the detection chamber 1. This allows the exhaust gas to diffuse evenly into the detection chamber 1, preventing the exhaust gas from directly impacting the detection sensor 7 or other components and affecting the accuracy of the test results. It also helps to improve the contact effect between the exhaust gas and the filter plate 62 and the drying plate 63 in the auxiliary component 6, enhancing the pretreatment effect of the exhaust gas.

[0028] Referring to Figures 3 and 5, the auxiliary component 6 includes a slide rail 61, which is detachably connected to the upper surface of the inner wall of the detection chamber 1. The slide rail 61 provides a track for the installation and support of the filter plate 62 and the drying plate 63. The detachable design of the slide rail 61 facilitates the replacement, cleaning, and maintenance of the filter plate 62 and the drying plate 63, ensuring that the auxiliary component 6 can stably perform its filtering and drying functions for a long time. The structure of the slide rail 61 also facilitates the positioning and fixing of the filter plate 62 and the drying plate 63 inside the detection chamber 1, ensuring the accuracy of their installation position. Filter plates 62 are fixedly installed on both the left and right surfaces of the slide rail 61. The filter plates 62 are used to filter and intercept fine particulate matter, dust, and other impurities in the industrial waste gas entering the detection chamber 1, preventing these impurities from entering the detection chamber 1 and affecting the normal operation and detection accuracy of the detection sensor 7. At the same time, it also helps to extend the service life of the detection sensor 7 and ensure the long-term stable operation of the detection device. The drying plate 63 is slidably connected to the lower surface of the slide rail 61. The drying plate 63 is used to adsorb moisture in the industrial waste gas and reduce the humidity of the waste gas.

[0029] Working principle:

[0030] Industrial waste gas enters the detection chamber 1 through the inlet pipe 31. After the motor 8 starts, it drives the rotating column 33 to rotate, and the fan blades 34 rotate accordingly to generate suction, ensuring that the waste gas can be smoothly drawn into the detection chamber 1 from the inlet pipe 31. The eccentric wheel 35 on the rotating column 33 rotates with the rotating column 33, generating centrifugal force that acts on the pad 36, thereby affecting the elastic telescopic rod 37 and the wind vane 38. Under the combined action of the elastic telescopic rod 37 and the eccentric wheel 35, the wind vane 38 swings, guiding and adjusting the flow direction of the waste gas entering the detection chamber 1, so that the waste gas is evenly distributed in the detection chamber 1, avoiding the waste gas from directly impacting the detection sensor 7 or other components, and at the same time improving the contact effect between the waste gas and the filter plate 62 and the drying plate 63 in the auxiliary component 6, thus enhancing the pretreatment effect of the waste gas.

[0031] After entering the detection chamber 1, the exhaust gas first passes through the filter plate 62. The filter plate 62 is installed on the left and right surfaces of the slide rail 61 to filter and intercept particulate matter, dust, and other impurities in the exhaust gas, preventing these impurities from affecting the normal operation and detection accuracy of the detection sensor 7, and extending the service life of the detection sensor 7. The exhaust gas then passes through the drying plate 63, which is slidably connected to the lower surface of the slide rail 61. The drying plate 63 is used to absorb moisture in the exhaust gas, reducing its humidity and ensuring stable humidity of the exhaust gas entering the detection area, thereby improving the accuracy and reliability of the detection.

[0032] The detection sensor 7 is fixedly installed on the inner wall of the detection chamber 1 to accurately detect the components and concentrations of various pollutants in industrial waste gas, such as sulfur dioxide, nitrogen oxides, and volatile organic compounds. The detection sensor 7 converts the detected waste gas components and concentration information into electrical signals, which are transmitted to the control panel 2 through its signal terminal circuit. The control panel 2 receives the electrical signals transmitted by the detection sensor 7, processes, displays, and stores the signals, providing operators with real-time and accurate waste gas emission monitoring data for effective monitoring and management of industrial waste gas emissions. Finally, the detected waste gas is discharged from the detection device through the exhaust pipe 5. The exhaust valve 4 controls the opening and closing of the exhaust pipe 5 and the flow rate of the discharged waste gas, ensuring that the waste gas emissions meet relevant environmental protection requirements and the needs of the detection process, maintaining the pressure balance inside the detection chamber 1, and ensuring the stable operation of the detection process.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
