Causes and Solutions for Filter Bag Blockage

Cause Analysis:

1. Air leakage or low flue gas temperature causing condensation, pipe leakage, and wet bags leading to dust adhesion.

2. Excessive filtration speed, very fine or coarse dust, sticky dust, and poor filter bag cleaning.

3. Insufficient pulse cleaning time and cycle.

4. Low pulse pressure, weak pulse cleaning.

Solutions:

1. Insulate or heat the dust collector, prevent rain, and avoid air leakage.

2. Pre-collect dust before pulse cleaning, reduce filtration speed, and control the amount of cooling water spray.

3. Observe the pressure difference and adjust the pulse cleaning time and cycle.

4. Adjust the pulse pressure.

Efficient and stable operation of dust removal equipment is crucial. Any malfunction in the equipment directly affects dust removal efficiency and environmental protection.
