3.1 principle of dust recovery
The dust will fly to the bag house with airflow and spread around to the surface
of the bag house equaly When the air with dust come from the air pipe or
flange into the dust catcher. The dust will be stay outside of the bag house .and
the air which has passed the bag house will get through the filter gate into the
upside of air purification box .Then it will be atmospheric deposition through
the exit exhaust fan. Some of the accumulation dust which attached to the
outside of the bag house will drop into the ash hopper and some will stay still .
And will make the installations resistance rise up .To make sure the
installations resistance not exceeding 1500 PA . A thorough dust clean should
be taken after few period .
3.2principle of air blast
The drawing for the principle of air blast is as follow. The principle is the A
head joint of the pulse valves will compress by-pass tube and the B head joint
3will blowing the Venturi meter. the pulse valves backpressure house connect
with the air exhaust valves. And the air exhaust valves is controlled by PLC.
The exhaust port will be sealed by
