Dust Collectors

One of the primary means of controlling particles released from an expansion chamber
Is. The gas velocity in this chamber is reduced to some extent by using particles
The force of gravity is capable of settling.

Used in various industries and mainly for the removal of coarse particles
The flow of air is applied to a range of 60-40 μm.
The main mechanism for separating particles in this dust collector is based on the gravity of the earth
While in other dust collectors, particle separation with this mechanism has a small contribution
Collecting particles.
The pressure drop of these chambers is low and usually less than g.w.in 2.
Benefits: Simple structure, low cost and low maintenance, low pressure drop and simple disposal
Particles taken
Basically, there are two types of gravel precipitators that are: Expansion chamber
Simple and multi-level sedimentation chamber
An expansion chamber resembles a long horizontal box consisting of an input, an outlet and
Hopper. The air flow through the entrance of the machine into an expanded chamber
And there the speed of the air flow decreases.
Decreasing the airflow to 10-1 s / ft causes the coarse particles to settle
It is affected by the gravity of the earth.
Theoretically, an unlimited length cavity can collect particles
Too small (μm 10>).
The effective sedimentation rate of the particles decreases with increasing flow turbulence
The gas flow rate in this chamber should be as low as possible. High speed
It also causes the resinous particles to rise again. On the other hand, very slow speeds also increase the size of the chamber.
