Self-Oscillating Nozzle for Pulse-Jet Cleaning

The single-hole nozzle is segmented into multiple holes arranged in specific patterns (e.g., triangular, square, or hexagonal arrays). This segmentation allows multiple pressure waves to be generated simultaneously during back-flushing, improving cleaning efficiency and uniformity without requiring complex external control systems

The multi-hole nozzle creates periodic pressure waves that propagate through the filtration element in a coordinated sequence. The periodic action ensures comprehensive coverage of the filtration surface, addressing non-uniform cleaning issues while maintaining a relatively simple nozzle structure

Different holes in the nozzle are designed with different diameters, orientations, or flow rates to create localized pressure distributions tailored to specific cleaning needs. This allows effective deashing while distributing thermal and mechanical stress more evenly, reducing vibration and thermal impact on the filtration pipeline

The nozzle design incorporates dynamic flow characteristics where multiple pressure waves are generated in a controlled sequence rather than a single high-pressure impulse. This dynamic approach achieves effective cleaning while reducing peak pressure impacts and thermal shock to the filtration element

The nozzle is segmented into multiple holes with specific geometric arrangements that naturally generate multiple pressure waves. The segmentation is achieved through straightforward structural design rather than complex mechanical or electronic systems, improving regeneration efficiency while maintaining manufacturing simplicity

The nozzle parameters (hole diameter, spacing, arrangement pattern, orientation) are optimized to control the generation and propagation of multiple pressure waves. By adjusting these parameters, efficient cleaning is achieved without requiring complex active control mechanisms
