Description

Technical Field

[0001] This utility model relates to the field of soot blowing technology, specifically a flame deflector array soot blower. Background Technology

[0002] The bottom of the flue at the flame deflector of the horizontal flue often accumulates a large amount of fine ash and coke residue. Not only does the ash accumulate rapidly, but the thickness of the ash at the flame deflector can reach 1 to 1.5 meters, forming an ash wall. If this ash wall is not removed in time, when it reaches a certain thickness and height, it will reduce the cross-sectional area of ​​the flue gas flow at the furnace outlet, resulting in a decrease in flue gas flow, an increase in furnace pressure, and a reduction in the heat absorption of the boiler's tail heating surface. Therefore, it is necessary to use a soot blower intermittently for cleaning.

[0003] Existing flame deflector array sootblowers, when optimized, mostly feature the ability to adjust the blowing airflow size according to the amount of dust. For example, Chinese utility model patent application number CN202120051640.0 discloses "A Flame Deflector Array Sootblower". In this device, a pipe is included, a connecting pipe is fixedly installed on the lower side wall of the pipe, and a sootblower is fixedly installed at the lower end of the connecting pipe. The sootblower has a cavity inside, and symmetrical air outlets are opened on the side wall of the cavity. A lead screw is rotatably installed inside the cavity via a bearing. Symmetrical limiting plates are fixedly installed at both ends of the lead screw. A slider is threadedly connected to the rod wall of the lead screw. Both limiting plates have strip-shaped openings on their side walls. Symmetrical extrusion blocks are fixedly installed at both ends of the sliders. Adjustment mechanisms are fixedly installed at both ends of the extrusion blocks. A protective cover is installed on the outside of the sootblower, and symmetrical mounting blocks are fixedly installed at both ends of the protective cover. This allows for adjustment of the blowing airflow size according to the amount of dust accumulation, increasing the practicality of the sootblower.

[0004] While the aforementioned flame deflector array sootblower has certain advantages in adjusting the sootblowing airflow according to the amount of dust, it still has some drawbacks: the sootblower usually only has one nozzle to spray gas to achieve the effect of cleaning dust, and different flame deflectors have different area areas. If cleaning a longer flame deflector, personnel need to constantly adjust the position of the sootblowing nozzle, which consumes manpower and takes a long time to clean. Utility Model Content

Through the set drive component 21, when the output end of the speed reducer 26 drives the ring frame 23 to rotate, the limit block 212 cooperates with the limit of the ring frame 23, allowing the soot blowing pipe 211 to rotate with the ring frame 23. The soot blowing nozzle 1 is installed above the soot blowing pipe 211 through the mounting plate 214, which facilitates the rotation of the soot blowing nozzle 1, and the gas can be input into the interior of the soot blowing nozzle 1 through the connecting column 213.

The front end of the electric telescopic rod 32 is connected to the lower part of the soot blowing nozzle 1 through the hanging part 31. The rotating plate 33 can move along the limit rail 35 in a circular trajectory under the drive of the rotating wheel 34, so that the electric telescopic rod 32 can rotate with the rotation of the soot blowing nozzle 1. At the same time, the telescopic deformation of the electric telescopic rod 32 can be adjusted, so that the electric telescopic rod 32 can drive the soot blowing nozzle 1 to move back and forth, thereby making the soot blowing nozzle 1 flexible enough to rotate and move back and forth, increasing the soot blowing area for the flame deflector angle, without the need for the operator to constantly change the position of the entire device to adjust the soot blowing position of the soot blowing nozzle 1.
