A common fault analysis of asphalt mixing plant - the fault and solution of the dust collector

1. Dust leakage

Open the upper cover plate of baghouse dust collector, and check for cloth bag, take corresponding measures according to condition. Cleaning dust on the top of upper chamber, check if there is dust into the bag.

2. The problem of bag

a. the temperature of dust gas is too high

The temperature of dust gas must not exceed the maximum allowable temperature. The cloth bag can generally be under 200℃ high temperature, if the inlet temperature more than this value, the damper should be opened for the introduction of cold air cooling.

b. the humidity is too large

The bag is blocked if the climate is wet, so the wet cloth bag should be dried or replaces a new bag.

c. dust accumulation

If the dust accumulates at the bottom of the bag in the dust collector, the bag will accelerate wear. At this time, you shall check the running status of dust discharging device and check for leaks, and take corresponding measures.

d. bag wear

The inside of bag is dirty, because the dust is into the bag, which also caused the wear. In addition, if the dust is accumulated in the powder outlet, in order to prevent bag damage, the powder feeding device of the dust collector should be checked and the dust bag should be replaced.
