The air inlet of the smoke pump 12 is connected with a smoke inlet cylinder 11 through a pipe body. The inside of the smoke inlet cylinder 11 is provided with a dust concentration sensor 15. The heat exchange pipe 9 and the straight pipe 10 are both communicated with one end of the smoke inlet cylinder 11 away from the three-way electromagnetic valve 8. The inner wall of the smoke inlet pipe 3 is provided with a temperature sensor 13.

[0023] In use, flue gas enters the three-way electromagnetic valve 8 through the smoke inlet pipe 3. The three-way electromagnetic valve 8 can control the opening and closing of the straight pipe 10 or the heat exchange pipe 9, so that the high-temperature flue gas can pass through the straight pipe 10 or the heat exchange pipe 9 and then enter the smoke inlet cylinder 11. In the smoke inlet cylinder 11, the dust concentration sensor 15 collects the concentration data of fine particulate matter in the flue gas, and the smoke pump 12 continuously extracts the flue gas to ensure stable flow.

[0024] Further, the inner wall of the shell 1 is provided with an internally threaded cylinder 14, the outer wall of the smoke inlet pipe 3 is provided with external threads, and the outer wall of the smoke inlet pipe 3 is threadedly connected to the inner wall of the internally threaded cylinder 14. The smoke inlet pipe 3 can penetrate the internally threaded cylinder 14 and be connected to the air inlet of the three-way electromagnetic valve 8. When connected, the smoke inlet pipe 3 is rotated to connect the external threads of the outer wall to the internal threads of the inner wall of the internally threaded cylinder 14, thereby fixing the position of the smoke inlet pipe 3.

[0025] In this embodiment, as shown in the drawings, Figure 1 The outer wall of the shell 1 is provided with a controller 6. The temperature sensor 13 is signal connected to the controller 6. The controller 6 is electrically connected to the smoke pump 12 and the three-way electromagnetic valve 8. The temperature sensor 13 in the smoke inlet pipe 3 monitors the temperature of the flue gas in real time. When the temperature of the flue gas is detected to be higher than the preset value, the controller 6 controls the three-way electromagnetic valve 8 to close the straight pipe 10 and open the heat exchange pipe 9, so that the high-temperature flue gas first passes through the heat exchange pipe 9 and then enters the smoke inlet cylinder 11, preventing the high-temperature flue gas from directly affecting the measurement accuracy and service life of the sensor.

[0026] It should be noted that the heat exchange pipe 9 is a serpentine copper pipe, and the serpentine structure of the copper pipe can increase the flow length of the high-temperature flue gas and improve the cooling effect.

[0029] Specifically, two connecting plates 7 are symmetrically installed at the bottom of the shell 1, and the shell 1 can be fixed in the flue gas discharge area by penetrating the connecting plate 7 with a fixing member.

[0030] According to the above technical scheme, the working steps of the present scheme are summarized and combed: when the present application is used, the flue gas enters the three-way electromagnetic valve 8 through the smoke inlet pipe 3, wherein the temperature sensor 13 in the smoke inlet pipe 3 monitors the flue gas temperature in real time, when the flue gas temperature is detected to be higher than the preset value, the controller 6 controls the three-way electromagnetic valve 8 to close the straight pipe 10 channel and open the heat exchange pipe 9 channel, so that the high-temperature flue gas is cooled first through the heat exchange pipe 9 and then enters the smoke inlet pipe 11, in the smoke inlet pipe 11, the dust concentration sensor 15 collects the fine particle concentration data in the flue gas, at the same time, the smoke pump 12 continuously extracts the flue gas to ensure stable flow, this process can effectively prevent the high-temperature flue gas from directly affecting the measurement accuracy and service life of the sensor, and at the same time ensure the reliability and accuracy of data acquisition.
