This invention relates to a multi-dimensional dynamic jet
soot blowing device for boiler flues, comprising a
flue wall and a
soot blowing device body. The device includes components such as a track, support base,
nozzle,
compressed air tank, and controller. The support base slides along the track, driving the
nozzle to extend and retract. The
nozzle can rotate to adjust the spray angle, achieving
soot blowing throughout the entire
flue without dead angles. The nozzle is connected to a gas delivery hose via a rotating
pipe joint, ensuring a good seal and effectively preventing gas leakage. The equipment employs a gear and rack transmission structure, combined with a
limit switch and
servo motor, to precisely control the nozzle's extension and retraction
stroke, rotation angle, and speed. It also presets three commonly used spray angles for accurate positioning. The device supports both automatic and manual control
modes, offering simple operation and ensuring
personnel safety. A dust baffle is installed at the
flue inlet, and an automatically resetting baffle is provided at the nozzle outlet to prevent dust overflow and
backflow. The inclined design at the nozzle's front end prevents high-pressure
airflow from impacting the flue wall. The overall structure is pressure- and
impact-resistant, and
assembly and maintenance are convenient.
