Description

Technical Field

[0001] The utility model relates to the technical field of flue gas monitoring, in particular to a continuous flue gas emission monitoring device based on multi-point matrix flow measurement technology. Background Art

[0002] The existing continuous flue gas emission monitoring devices face many challenges in practical applications. First of all, due to the different heights of industrial emission sources, traditional monitoring devices often have difficulty flexibly adapting to the flue gas collection requirements at different heights. This results in that during the monitoring process, it may not be possible to comprehensively and accurately collect flue gas samples at a specific height, thus affecting the representativeness and accuracy of the monitoring results. Secondly, during the process of the sampling device moving to adjust the height, the existing device design often lacks an effective sealing mechanism. This allows flue gas at other heights to easily enter the sampling system through the intake pipe during the movement of the sampling device, causing pollution to the sampling structure and affecting the accuracy of subsequent flue gas component analysis. Therefore, a continuous flue gas emission monitoring device based on multi-point matrix flow measurement technology is proposed to solve the above problems. Content of the Utility Model

The driving mechanism 7 includes a placement box 2 installed on one side of the top surface of the support plate 6, and a motor 701 is installed on the inner bottom wall of the placement box 2. The output end of the motor 701 is installed with a rotating cylinder 702, a connecting rope 703 is arranged on the outer wall of the rotating cylinder 702, a moving plate 704 is slidably sleeved on the outer wall of the support plate 6, a first hanging ring 705 is installed in the middle of the top surface of the moving plate 704, a second hanging ring 706 is sleeved on the outer wall of the first hanging ring 705, and the second hanging ring 706 is fixedly connected with the connecting rope 703. A fixing mechanism 8 is arranged on the top surface of the moving plate 704, and the fixing mechanism 8 is used to fix the moving plate 704 and the placement box 2 together. The fixing mechanism 8 includes limiting rods 801 symmetrically installed on the top surface of the moving plate 704, fixing plates 802 are symmetrically installed on the top surface of the placement box 2, and a connecting hole is opened on one side of the top surface of the fixing plate 802. The end of the limiting rod 801 away from the moving plate 704 penetrates through the connecting hole and a nut 803 is installed at the end. An air outlet is opened on the top surface of the placement box 2, and a sealing cover 10 is threadedly connected to the outer wall of the air outlet. Anti-slip plates are annularly arranged on the outer wall of the sealing cover 10. A bearing plate 9 is installed on the bottom surface of the support plate 6, and through holes are symmetrically opened on the top surface of the bearing plate 9. The closing mechanism 5 includes a motor 501 installed on one side of the inner wall of the installation box 1. The output end of the motor 501 is installed with a rotating rod 502, the end of the rotating rod 502 away from the motor 501 penetrates through the intake pipe 3 and a gear 503 is installed at the end. An installation plate 504 is slidably connected to the inner wall of the end of the intake pipe 3. A movable rod 505 is installed on one side of the outer wall of the installation plate 504. Connecting plates are symmetrically installed on both sides of the outer wall of the movable rod 505, and a limiting ring 506 is installed at the end of the connecting plate away from the movable rod 505. A connecting groove is opened on one side of the outer wall of the movable rod 505, and a rack 507 is installed on the inner wall of the connecting groove. The gear 503 is meshed with the rack 507.

A limiting groove is opened on the inner wall of the intake pipe 3, and the limiting groove is slidably connected with the limiting plate 508.

[0025] During the working process, the staff can turn on the motor 701, so that the motor 701 drives the rotating cylinder 702 to rotate. As the rotating cylinder 702 rotates, the connecting rope 703 starts to wind or unwind, thereby applying a tensile force or releasing a tensile force to the second lifting ring 706. The second lifting ring 706 transmits the tensile force to the moving plate 704 through the first lifting ring 705, causing the moving plate 704 to slide up or down on the support plate 6. Since the placement box 2 is fixed on the moving plate 704, the placement box 2 also moves up or down with the moving plate 704, so that the position of the installation box 1 can be adjusted. Since the air inlet pipe 3 is installed on one side of the outer wall of the installation box 1, the height of the air inlet pipe 3 can be adjusted to collect flue gas at different heights. The specific operation of the collection is as follows. The staff can turn on the air pump 401, so that the air inlet of the air pump 401 transports the flue gas through the air inlet pipe 3 and the first connecting pipe 402 to the inside of the second connecting pipe 403, and then enters the inside of the placement box 2 through the second connecting pipe 403 to achieve the collection of the flue gas. In addition, in order to prevent flue gas at different heights from entering the air inlet pipe 3 during the movement of the installation box 1 and causing pollution to the sampling structure, the present invention is provided with a sealing mechanism 5. During the movement of the placement box 2, the mounting plate 504 is located inside the air inlet pipe 3, which can prevent the flue gas from entering the inside of the air inlet pipe 3 along the port of the air inlet pipe 3. After reaching the specified height, the staff can turn on the motor 501, so that the output end of the motor 501 drives the rotating rod 502 to rotate. When the rotating rod 502 rotates, it drives the gear 503 to rotate. Since the rack 507 meshes with the gear 503, the gear 503 drives the movable rod 505 to move horizontally during rotation. When the movable rod 505 moves away from the motor 501, it gradually disengages from the air inlet pipe 3, so that the flue gas can enter the inside of the connecting pipe along the gap between the movable rod 505 and the air inlet pipe 3. With the setting of the air pump 401, the flue gas can be transported to the inside of the placement box 2. Then, after the collection is completed, the staff can drive the motor 501, so that the output end of the motor 501 drives the rotating rod 502 to rotate in the reverse direction, thereby driving the gear 503 to rotate in the reverse direction. When the gear 503 rotates in the reverse direction, it drives the rotating rod 502 to move towards the motor 501, thereby driving the mounting plate 504 to move towards the motor 501 until the mounting plate 504 is located inside the air inlet pipe 3, and the air inlet pipe 3 can be blocked by the mounting plate 504 to prevent flue gas at other heights from entering the inside of the air inlet pipe 3 during the upward movement of the air inlet pipe 3. Finally, when the installation box 1 moves up to the uppermost position, the staff can rotate the nut 803 to disengage the nut 803 from the limit rod 801, and then can lift the installation box 1 upward, so that the placement box 2 can move upward and the placement box 2 can be disengaged from the limit rod 801. Since the installation box 1 is fixedly connected to the placement box 2, the placement box 2 and the installation box 1 can be disassembled. After taking them out, they can be sent to the laboratory for inspection. The staff can rotate the sealing cover 10, through the air outlet,Use a syringe to suck the flue gas inside the placement box 2, which is convenient for the laboratory to analyze the composition of the flue gas.
