Description

Technical Field

[0001] This utility model relates to the field of flue gas detection, specifically to an environmental detection device for flue gas emissions. Background Technology

[0002] Flue gas is a mixture of gases and particulate matter, and is a major cause of air pollution in residential areas. The composition of flue gas is very complex. The gases include water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides, while the particulate matter includes fuel ash, coal particles, oil droplets, and high-temperature pyrolysis products.

[0003] Existing environmental monitoring devices for flue gas emissions generate a large amount of particulate matter. This particulate matter directly enters the monitoring device and adheres to some sensors, leading to inaccurate measurement results. Furthermore, traditional flue gas emission monitoring devices lack filtration mechanisms, allowing particulate matter to directly enter the monitoring device, which not only affects the detection effect but also reduces the lifespan of the sensors.

[0004] Therefore, it is necessary to invent an environmental monitoring device for flue gas emissions to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an environmental monitoring device for flue gas emissions. Flue gas enters a filter box containing two sets of filter plates, which filter particulate matter in the flue gas. Long-term use prevents clogging of the filter plate surface. By turning on a micro-motor switch, a transmission rod and two sets of external contact blocks rotate. During rotation, the contact blocks push the filter plates left and right, and the filter plates rebound using an internal connecting rod and an external spring, knocking off surface-clogging particles and collecting them in a collection box. This addresses the problem in existing flue gas emission monitoring devices mentioned in the background art, where flue gas emissions generate a large amount of particulate matter. These particles directly enter the monitoring device and adhere to some sensors, leading to inaccurate measurement results. Furthermore, traditional flue gas emission monitoring devices lack a filtration mechanism, allowing particulate matter to directly enter the monitoring device, which not only affects the detection effect but also reduces the lifespan of the sensors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmental monitoring device for flue gas emissions, comprising a filter box; used for flue gas emission filtration;

[0007] A flange connecting pipe is fixedly connected to the left side of the filter box for connecting equipment pipelines. A first frame is slidably connected inside the flange connecting pipe. Connecting rods are fixedly connected to both sides inside the first frame. A filter plate slides through the outside of the connecting rods. A spring is sleeved on the outside of the connecting rods. A micro motor is fixedly installed above the filter box. A transmission rod is fixedly connected to the output end of the micro motor. A contact block is fixedly connected to the outside of the transmission rod.

[0008] A collection tank, located below the filter box, is used to collect particulate matter, and the collection box is slidably connected inside the collection tank;

[0009] The detection box, installed on the right side of the filter box, is used to detect flue gas. An electrochemical sensor, an infrared sensor, and a temperature and humidity sensor are fixedly installed inside the detection box. An organic box is fixedly installed on the upper right side of the detection box.

[0010] Preferably, a second frame is slidably connected below the filter plate, and the interior of the second frame is hollow.

[0011] Preferably, the contact blocks are provided in two sets, and the two sets of contact blocks are aligned with the upper and lower inner sides of the filter plate, and the contact blocks are oval in shape.

[0012] Preferably, the inner wall of the collection box is fitted with a sealing element, and the external dimensions of the collection box match the internal dimensions of the collection tank.

[0013] Preferably, the housing is equipped with a data acquisition module and a wireless communication module, and an interface is provided on the front of the housing.

[0014] Preferably, the input terminals of the electrochemical sensor, infrared sensor, and temperature and humidity sensor are electrically connected to the output terminals of the housing.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By setting up a filter box, a first frame, a connecting rod, a filter plate, a spring, a second frame, a micro motor, a transmission rod, and contact blocks, the system can filter flue gas during detection, preventing large particles from adhering to the sensor and affecting detection. Flue gas enters the filter box through two sets of filter plates, which filter the particulate matter in the flue gas. Long-term use prevents the filter plate surface from becoming clogged. By turning on the micro motor switch, the transmission rod and the two sets of contact blocks on the outside rotate. During the rotation of the contact blocks, they push the filter plate left and right by pushing back and forth. The filter plate rebounds using the internal connecting rod and the external spring, thereby knocking the clogged particles off the surface and collecting them in the collection box.

[0017] 2. By configuring the detection box, electrochemical sensor, infrared sensor, temperature and humidity sensor, and control unit, the concentration, temperature, and humidity of flue gas can be effectively detected. Filtered flue gas enters the detection box. The electrochemical sensor generates an electric current through the chemical reaction between the gas and the electrode. The magnitude of the current is measured to determine the gas concentration. The infrared sensor utilizes the absorption characteristics of gas molecules for specific wavelengths of infrared light to determine the concentration through spectral analysis. Finally, the temperature and humidity sensor detects the temperature and humidity in the flue gas. The data detected by the electrochemical sensor, infrared sensor, and temperature and humidity sensor are transmitted to the data acquisition module inside the control unit. After analysis by the data acquisition module, the data is transmitted to the wireless communication module, and finally, the wireless communication module transmits the data to the communication device of the testing personnel for viewing.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-7 An environmental monitoring device for flue gas emissions is shown, including a filter box 1 for filtering flue gas emissions.

[0030] Flange connecting pipe 2 is fixedly connected to the left side of filter box 1 and is used to connect equipment pipeline. The first frame 3 is slidably connected inside the flange connecting pipe 2. The connecting rod 4 is fixedly connected to both sides inside the first frame 3. The filter plate 5 slides through the outside of the connecting rod 4. The spring 6 is sleeved on the outside of the connecting rod 4. A micro motor 8 is fixedly installed above the filter box 1. The output end of the micro motor 8 is fixedly connected to the transmission rod 9. The transmission rod 9 is fixedly connected to the outside of each of the transmission rods 9.

[0031] The collection tank 11 is located below the filter box 1 and is used to collect particulate matter. The collection box 12 is slidably connected inside the collection tank 11.

[0032] The detection box 14 is installed on the right side of the filter box 1 and is used to detect flue gas. An electrochemical sensor 15, an infrared sensor 16, and a temperature and humidity sensor 17 are fixedly installed inside the detection box 14. An organic box 18 is fixedly installed on the upper right side of the detection box 14. When flue gas enters the two sets of filter plates 5 in the filter box 1, the filter plates 5 are used to filter the particulate matter in the flue gas. To prevent the surface of the filter plates 5 from becoming clogged with long-term use, the micro motor 8 is turned on, which drives the transmission rod 9 and the two sets of external contact blocks 10 to rotate. During the rotation of the contact blocks 10, they push the filter plates 5 to move left and right. The filter plates 5 rebound by the internal connecting rod 4 and the external spring 6, thereby knocking the particulate matter clogged on the surface off and into the collection box 12 for collection.

[0033] like Figure 2 and Figure 3 As shown, a second frame 7 is slidably connected to the bottom of the filter plate 5. The interior of the second frame 7 is hollow. The filter plate 5 slides outward through the connecting rod 4 inside the second frame 7 via the first frame 3. The bottom of the second frame 7 is hollow to prevent particles that fall after the filter plate 5 is hit from falling into the second frame 7.

[0034] like Figure 2 and Figure 4As shown, there are two sets of contact blocks 10. The two sets of contact blocks 10 are aligned with the upper and lower inner sides of the filter plate 5. The contact blocks 10 are oval. By turning on the micro motor 8 switch, the transmission rod 9 and the two sets of contact blocks 10 are driven to rotate. During the rotation of the contact blocks 10, they push the filter plate 5 to move left and right. The filter plate 5 uses the internal connecting rod 4 and the external spring 6 to rebound, thereby shaking back and forth and knocking the particles that are blocked on the surface into the collection box 12 for unified collection.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, the inner wall of the collection box 12 is inlaid with a sealing element 13. The external dimensions of the collection box 12 match the internal dimensions of the collection groove 11. The collection box 12 is inside the collection groove 11. The sealing element 13 on the inner side of the collection box 12 is attached to the outside of the collection groove 11 to enhance the sealing performance and prevent the internal smoke from drifting out.

[0036] like Figure 1 , Figure 6 and Figure 7 As shown, the housing 18 is equipped with a data acquisition module and a wireless communication module. An interface is provided on the front of the housing 18. Through the data acquisition module and wireless communication module inside the housing 18, sensor detection data can be acquired, and then the acquired data can be transmitted to the communication device of the testing personnel for observation through the wireless communication module.

[0037] like Figure 6 and Figure 7 As shown, the input terminals of the electrochemical sensor 15, infrared sensor 16, and temperature and humidity sensor 17 are electrically connected to the output terminals of the housing 18. When the filtered flue gas enters the detection box 14, the electrochemical sensor 15 generates a current through the chemical reaction between the gas and the electrode, and the gas concentration is determined by measuring the current magnitude. The infrared sensor 16 uses the absorption characteristics of gas molecules to infrared light of a specific wavelength to determine the concentration through spectral analysis. Finally, the temperature and humidity in the flue gas are detected by the temperature and humidity sensor 17. The data detected by the electrochemical sensor 15, infrared sensor 16, and temperature and humidity sensor 17 are transmitted to the data acquisition module in the housing 18. After analysis by the data acquisition module, the data is transmitted to the wireless communication module, and finally transmitted to the communication device of the testing personnel for viewing.

[0038] The working principle of this practical device is as follows: First, the flange connecting pipe 2 on the left side of the filter box 1 is threadedly connected to the exhaust pipe, and the other end of the detection box 14 is threadedly connected to the exhaust pipe. This simple setup of the filter box 1 and collection box 12 is more convenient and environmentally friendly compared to traditional large-scale detection equipment. After installation and connection to an external power source, when the flue gas enters the filter box 1 through the flange connecting pipe 2 and is exposed to the two sets of filter plates 5, the filter plates 5 filter the particulate matter in the flue gas. During filtration, blockage inevitably occurs on the surface of the filter plates 5. At this point, turning on the micro motor 8 switch on top of the filter box 1 drives the transmission rod 9 and the two sets of external contact blocks 10 to rotate. During rotation, the contact blocks 10 push the filter plates 5 left and right, and the two sets of filter plates 5 utilize the internal four connecting rods 4 and the external spring 6 to bounce back, thus shaking the surface of the filter plates. The clogged particles are knocked down and collected in the collection box 12. Then, when the filtered flue gas enters the detection box 14, the electrochemical sensor 15 first generates an electric current through the chemical reaction between the gas and the electrode. The magnitude of the current is measured to determine the gas concentration. Next, the infrared sensor 16 uses the absorption characteristics of gas molecules to infrared light of a specific wavelength to determine the concentration through spectral analysis. Finally, the temperature and humidity sensor 17 detects the temperature and humidity in the flue gas. The data detected by the electrochemical sensor 15, the infrared sensor 16, and the temperature and humidity sensor 17 are transmitted to the data acquisition module in the housing 18. After analysis by the data acquisition module, the data is transmitted to the wireless communication module. Finally, the data is transmitted to the communication device of the testing personnel to view the obtained data. In this way, the use of the environmental monitoring device for flue gas emissions is completed.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
