. Summarization of operation principle of bag type dust collector

1. Operation

Dirty air moves into duster, cross it through bags. Because vacuum is built by exhaust fan, so, clean air can enter bags, but dusts remain outside.

Clean air goes upward, across bags, at the same time, dust falls onto the screw conveyor and exit. The screw conveyor is a mechanic structure, and opens to atmosphere.

2. Cleaning cycle

During the running of screw conveyor, clean air from atmosphere is allowed to enter baghouse through its top, causing bend to bags, and causing dust to fall to collecting hopper.

3. Startup procedure

start discharging system, and rotary valve.

check and run the screw conveyor of duster.

start exhaust fan, and set air door to shut-off.

start burner and keep low flame 10 minutes, and only when the thermocouple indicate that the exhaust temperature reaches 120 , start aggregate feeding system.

4. Important clew

To prevent fibre from being damaged by high temperature, the warm-up cycle is remarkable.

Avoid too high temperature with director, when it reaches 120 , the cold-wind valve will open automatically; when it reaches 160 , computer will provide overheating alarm.

Ensure that burner control system, along with flame, can keep exhaust temperature under the highest value for fibre.

5. Stop procedure

brief stop(reach 5 minutes):

Keep all functional components running normally.

Metaphase stop (over 5 to 60 minutes)

cut off flame, then keep exhaust fan and dryer running.

only burner needs to be started, when start the facility anew.

Longer stop (over 60 minutes):

after flame cut off, before the facility stop sending out abundant dust, keep fan, counterblow, and discharging system running for at least 20 minutes.

restart facility according to primary start-up procedure.

Dust filter Maintenance
Check	open cover board, check counterblow system for running. The inlet air cylinders should be in-phase to counter-blowing period.
	are the bags of duster dry? Are all parts clean?
	check whether dusts has been discharged from duster with eyes.
	check coping airtight pad of each cover board for installation.
	check ventilation board on each bag jugular for air tightness.
	check dust-collecting pipe for dust status.
Weekly check	check dust-collecting pipe with eyes.
	check counterblow system.
	check clutch.
	check screw conveyors, gear case, chain, and middle bearing for lubrication.
Primary maintenance	bags The life of bags lie on many factors. Such as operating cycle, corruption, dust abrasion, high temperature and etc. We have discovered, due to various factors, the life will change between 3000 to 8000 hours. Except those near entry bags burning out for high temperature, the usual cause in common is, fibre loses intensity gradually or be abraded, and whole set bags have to be replaced.
Primary maintenance	installing and replacing of bags. Be sure to shut off facility, especially rotator valve, screw conveyor, and counterblow system. Take apart one steel cage, clean and check it for any damage, replace it if necessary.
