HEMS
2013 9th High Energy Materials
ECOLOGICAL THREATS
o Industrial dusts
o Nanodust
o Smoke of fires
2
HEMs 2013
PROBLEM and DESISION
One of decision – to add a liquid
aerosol for acceleration of a
coagulation and sedimentation of the
harmful smoke
3
PROBLEM: difficult sedimentation
of small particles
smoke The less are particles of the additional
aerosol, the better is the effect
HEMs 2013
REQUIREMENTS for SPRAY High speed of the creation, superfine
dispersion, autonomous, low energy expenses
4
HEMs 2013
Ultrasonic nebulizer:
+ Superfine,
- LOW speed,
- Demands an electricity
Pneumatic sprayer:
- TOO large particles,
+ HIGH speed,
+ Autonomous
Destruction of liquid streams: Cavitation:
+ HIGH Speed (< 1 sec),
+ HIGH dispersion (< 10 μm),
+ Autonomy,
+ Low energy (~ 150 J/g).
Decision is to use HEMs:
MODEL of EXPLOSIVE ATOMIZER • Usage of energy of HEM;
• Hydrodynamic cavitation;
• Ddrop~ 1…10 μm depending
on shock wave pressure.
