The pulse cleaning machine is commonly used in dust removal systems, especially in bag filters or cartridge filters. Its cleaning principle relies on compressed air pulses to remove dust accumulated on the filter media. Here are how it works:
Cleaning Principle:
Dust Accumulation:
Dust-laden air passes through filter bags/cartridges, leaving dust particles on the surface.
Over time, a dust cake forms, increasing pressure drop and reducing filtration efficiency.
Pulse Jet Cleaning:
A solenoid valve releases high-pressure compressed air (0.4~0.6 MPa) into a blow pipe with nozzles.
The air is directed into the filter elements, creating a shockwave that dislodges dust.
Reverse Airflow Effect:
The sudden air pulse causes a rapid expansion inside the filter, generating a reverse airflow.
This dislodges the dust layer, which falls into the hopper for disposal.
Cyclic Operation:
Cleaning is performed automatically in intervals (time-based or differential pressure-triggered).
Each pulse targets a specific section (sequential cleaning) to maintain continuous filtration.
Key Components:
Solenoid Valve: Controls compressed air release.
Diaphragm Valve: Ensures quick air blast.
Blow Pipe & Nozzles: Directs air into filters.
Filter Bags/Cartridges: Capture dust while allowing clean air passage.
Control System: Manages pulse timing and sequence.
Advantages:
✔ Efficient Cleaning: Removes dust without stopping operations.
✔ Low Energy Consumption: Short bursts of air minimize compressed air use.
✔ Extended Filter Life: Reduces wear compared to mechanical shaking.
✔ Automated Process: Requires minimal manual intervention.
Applications:
Industrial dust collectors (cement, steel, woodworking, etc.)
Power plants, chemical plants, food processing
Any system using baghouses or cartridge filters
