During the design of an efficient dust collection system for any application either
to control the air pollution or to prevent the dust posing accidents in the industries, it
is wise to control or minimize their emission at the source itself. In case of industrial
dust, this can often be achieved by investigating various approaches at an early
stage of process design and development and selecting those methods which do
not contribute to undesirable dust generation. These are known as source correction
methods. Application of these methods to existing plants is difficult, but still some
of these correction methods could be applied without severely upsetting economy of
the operation. Control of the dust at the source can be accomplished in several ways
of source correction methods as follows:
• Raw material changes
• Operational changes
• Modification/replacement of the existing process equipment
• More effective utilization of existing equipment.
Prioritzing all necessary key considerations required for safe handling of explosive
dust a collection system is designed in analytical approach by assuming a suction
air mover instead of a positive air mover. With the suction air mover, the tendency
of accidents is very less during the handling of the hazardous dusts.
Event tree analysis (ETA) is quantitative risk control technique that is applied to
the designed system and verified the safety adequacy of the system throughout and
of entire operating conditions applicable for the explosive machining process [4, 5].
It is inferred that the designed system is adequate to cater to the safety requirement
of dust collection system during explosive grain machining in aerospace as well as
defence applications.
4 Basic System and Components
Explosive dust collection system is freezed to be a group of (i) Gravitational settling
chamber, (ii) Cyclone separator, (iii) Wet scrubber and (iv) Bag hosing filter. In
addition to that systems, diving system (Vacuum air mover), Computer numerical
control to have automatic interface with the dust collection system with the machine
tool in order to operate it in a non-local mode to comply with the safety requirement
of potentially hazardous material machining.
5 System Life Cycle Verification
The system is verified for its safe performance under the appropriate conditions and
recorded the benefits that manual intervention is avoided by adapting a mechanical tilting arrangement of gravitational settling chamber as it is the major quantity
collecting chamber almost of 300 kg material as per the designed size. L/D ratio at
