Description

Technical Field

[0001] The utility model relates to the field of tail gas detection, in particular to a boiler tail gas monitoring device. Background Art

[0002] In industrial production, boilers are key equipment for heat conversion, and monitoring their exhaust emissions is crucial for environmental protection. However, traditional exhaust monitoring devices often face numerous challenges when working with different boiler chimneys, especially when chimneys vary in slope, size, and shape, making mounting and monitoring particularly challenging.

[0003] First, the varying slopes of chimneys make the installation of traditional monitoring devices inconvenient. The slope not only increases the difficulty of angle adjustment during installation, but can also affect the stability of the monitoring device during long-term use. When the chimney slope is large, the monitoring device is prone to displacement or tilt, leading to inaccurate monitoring results.

[0004] Secondly, the diversity of chimney sizes and shapes is also a problem that traditional monitoring devices are difficult to overcome; the chimneys of different boilers have significant differences in diameter, height, curvature and branch structure, which makes the design, customization and installation of fixed monitoring devices complicated and costly; for chimneys of special shapes or sizes, traditional monitoring devices may not be able to be installed directly, and complex modifications or customization are required, which increases the difficulty and period of installation.

[0005] Therefore, it is necessary to provide a new boiler exhaust gas monitoring device to solve the above technical problems. Utility Model Content

[0029] The working principle of the boiler exhaust gas monitoring device provided by the utility model is as follows:

[0030] Initial fixation of the connecting ring 2: First, according to the installation position of the chimney 1, the connecting ring 2 is placed on the outside of the chimney 1; then, by rotating the main threaded rod 10, the principle of thread transmission is used to make the multiple connecting seats 4 move relative to each other in the connecting ring 2 (either away from each other or closer to each other) to adapt to the change in the diameter of the chimney 1; in this way, the connecting ring 2 can be initially fixed on the chimney 1, laying the foundation for subsequent precise adjustment;

[0031] Slope adjustment: To accommodate variations in the slope of the chimney 1, the device is designed with a slope adjustment mechanism 7. The operator inserts a wrench into the hexagonal wrench hole and applies a rotating force. This rotational action drives the C-shaped rod 73 to rotate, which in turn drives the slide bar 74 to slide within the slide groove 71. Because the slide groove 71 is fixedly connected to the connecting seat 4, and the slide bar 74 is connected to the intermediate stop 5, the sliding of the slide bar 74 changes the angle between the intermediate stop 5 and the connecting seat 4. Through fine adjustment, the intermediate stop 5 can be closely attached to the slope of the chimney 1, ensuring the stability of the device on the sloped chimney 1.

[0032] Bending degree adjustment: For the bent chimney 1, this device adapts by adjusting the relative positions of the side abutting block 6 and the middle abutting block 5; First, by operating the installation ejector rod 84, the moving teeth inside it are separated from the fixed teeth two 86, thereby releasing the rotational locking of the side abutting block 6; Subsequently, the operator can freely rotate the side abutting block 6 to adjust the relative angle between it and the middle abutting block 5; Since the middle abutting block 5 is already closely attached to the inclined surface of the chimney 1 through the slope adjustment mechanism 7, the rotation of the side abutting block 6 will cause it and the middle abutting block 5 to jointly form an arc structure matching the bending degree of the chimney 1; In this way, the entire fixing system can closely adhere to the bent chimney 1, ensuring the stability of the monitoring device and the accuracy of the monitoring data;

[0033] Comprehensive adjustment and fixation: After completing the slope adjustment and bending degree adjustment, the operator needs to check the fastening conditions of each component again to ensure that all connections are firm and reliable; At the same time, adjust the position and angle of the monitoring probe as needed to ensure that it can accurately capture the tail gas emission data; Finally, lock all the adjustment mechanisms 7 to complete the final fixation of the monitoring device on the chimney 1.

[0034] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
