Description

Technical Field

[0001] This utility model relates to the technical field of flue gas flow rate and velocity monitoring, specifically a device for monitoring flue gas flow rate and velocity in complex pipelines. Background Technology

[0002] Flue gas flow rate and velocity monitoring refers to the process of measuring and monitoring the flow velocity and flow rate of flue gas in the flue. It is calculated by the flue gas flow rate and the cross-sectional area of ​​the flue. Monitoring devices are required to monitor the flow rate and velocity of flue gas.

[0003] As disclosed in CN206339269U, a gas flow monitoring device includes a differential pressure generator. The generator has an inlet on one side and an outlet on the other. A first differential pressure generator interface is located in a first cavity, and a second differential pressure generator interface is located in a second cavity. Pressure acquisition and analysis units are connected to both interfaces via wires, and pressure sensors are electrically connected to the pressure acquisition and analysis units. In this gas flow monitoring device, when the gas to be measured enters the differential pressure generator through the inlet's guide tube, the gas flow generates a Venturi effect, producing a pressure difference related to the airflow velocity. This pressure is collected by the pressure sensor, and the pressure analyzer processes the collected pressure to obtain the gas flow rate per unit time. Only one measurement is required, achieving low error and high accuracy.

[0004] However, existing technologies have problems such as inconvenience in quickly connecting and installing the device with the gas pipeline, the need to improve the sealing of the connection, and the inconvenience in adjusting the gas flow rate when the gas flow rate is too high. For example, the comparative patents listed above have this problem.

[0005] To address these issues, we propose a complex pipeline flue gas flow rate and velocity monitoring device. Utility Model Content

[0035] 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.

[0036] Please see Figures 1-9 The present invention provides the following technical solution.

[0037] Example 1: To address the problems in existing technologies, such as the inconvenience of quickly connecting the device to the gas pipeline 4 and the need to improve the sealing at the connection point, this example provides a complex pipeline flue gas flow rate and velocity monitoring device. The device includes a monitoring cylinder 1, a gas pipeline 4, a sealing ring 5, a fixing mechanism 6, a movable plate 9, a positioning plate 10, and a fixing bolt 11. The gas pipeline 4 on the left is the inlet pipe, and the gas pipeline 4 on the right is the outlet pipe. The gas pipelines 4 are respectively fitted onto the left and right sides of the monitoring cylinder 1, and a sealing ring 5 is fitted between the gas pipeline 4 and the monitoring cylinder 1. The gas pipeline 4 and the monitoring cylinder 1 are fixed by the fixing mechanism 6, and the fixing mechanism 6 drives the gas pipeline... The gas pipeline 4 and the monitoring cylinder 1 form a detachable structure. The fixing mechanism 6 includes a fixing sleeve 7 and a connecting plate 8. The fixing sleeve 7 is slidably connected to the left and right ends of the outer side of the monitoring cylinder 1, and the connecting plate 8 is hinged at an equal angle to the outer side of the fixing sleeve 7. The connecting plate 8 forms a flipping structure on the outer side of the monitoring cylinder 1, and the connecting plate 8 is engaged with the gas pipeline 4. Movable plates 9 are fixedly connected to both the upper and lower ends of the fixing sleeve 7, and the movable plates 9 are fitted with the positioning plates 10. The positioning plates 10 are hinged to the upper and lower ends of the monitoring cylinder 1, and the positioning plates 10 and the movable plates 9 are fixed by fixing bolts 11. The fixing bolts 11 and the positioning plates 10, as well as the fixing bolts 11 and the movable plates 9, are all threaded connections. Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, firstly, gas pipes 4 are respectively fitted onto the left and right sides of the monitoring cylinder 1, and the gas pipes 4 are tightly fitted with the sealing rings 5. The sealing rings 5 ​​improve the sealing effect at the connection. Then, by flipping the connecting plate 8, the connecting plate 8 rotates on the fixing sleeve 7. After the connecting plate 8 is flipped, it aligns with the gas pipes 4. Then, the fixing sleeve 7 is pulled towards the side closer to the vertical central axis of the monitoring cylinder 1, and the fixing sleeve 7 slides between the monitoring cylinder 1, thereby driving the connecting plate 8 to engage with the gas pipes 4, which facilitates the pressing and fixing of the gas pipes 4. Then, the positioning plate 10 is flipped, and the positioning plate 10 rotates on the monitoring cylinder 1, engaging with the movable plate 9. Then, the fixing bolt 11 is rotated to limit the position between the positioning plate 10 and the movable plate 9, fixing the fixing sleeve 7 and the monitoring cylinder 1. This allows for very quick docking and installation of the gas pipes 4 and the monitoring cylinder 1, with good sealing and fastening.

[0038] Example 2: To address the problems existing in the prior art, this example provides a complex pipeline flue gas flow rate and velocity monitoring device, comprising a monitoring cylinder 1, blades 2, and a display device 3. The blades 2 are rotatably mounted inside the monitoring cylinder 1, and the display device 3 is fixedly mounted on the upper end of the monitoring cylinder 1. Figure 1 , Figure 2 and Figure 3 As shown, the flue gas enters the monitoring cylinder 1 through the gas pipe 4 on the left and then exits through the gas pipe 4 on the right. The flue gas drives the blade 2 to rotate in the monitoring cylinder 1. By monitoring the speed and number of rotations of the blade 2 in the monitoring cylinder 1, the gas flow rate and velocity can be monitored. Moreover, the entire monitoring result can be displayed on the display device 3 for easy observation.

[0039] Example 3: To address the problem in existing technologies where it is inconvenient to adjust the gas flow rate when it is too high, this example provides a complex pipeline flue gas flow rate and velocity monitoring device. The device includes an adjustment mechanism located on the left side of the monitoring cylinder 1. The mechanism consists of a hollow plate 12, a connecting bolt 13, and a baffle 14. The hollow plate 12 is fixedly connected to the upper left end of the monitoring cylinder 1, and the upper end of the hollow plate 12 is threadedly connected to the connecting bolt 13 for adjustment. The lower end of the connecting bolt 13 is rotatably connected to the baffle 14, which is slidably connected to the middle of the hollow plate 12. The baffle 14 is telescopically connected within the monitoring cylinder 1, and a sealing gasket is fitted between the baffle 14 and the inner side of the monitoring cylinder 1. Figure 1 and Figure 9As shown, when the gas flow rate is too high, the connecting bolt 13, which is threadedly connected to the upper end of the hollow plate 12, can be rotated. The lower end of the connecting bolt 13 rotates with the baffle 14, thereby pushing the baffle 14 to slide in the hollow plate 12. The baffle 14 can move in the monitoring cylinder 1, which can control and adjust the flow rate of the flue gas.
