Fume Less Pickling
time in India, for in process continuous wire pickling operations, this
totally indigenous fumeless acid pickling line offers hassle-free pickling
with no air pollution related problems. This compact, totally covered unit
has built-in wire rinsing sections on each end of the line. There is no need
to install any air pollution control devices as fumes are not allowed to
escape. Made out of FRP and other engineering plastics it offers a long life
coupled with many other advantages for the first time to Indian Wire
Industries using acid for wire cleaning.
- World wide approved technology for wire pickling.
- Better pickling quality due to continuous heavy agitation of acid.
- Line speed can be further increased with acid heating provisions.
- Negligible acid loss.
- Uses no Scrubber, no Blower, no Hoods and no Chimney.
- Neat & clean surroundings of the pickling area.
- Compact unit with no high-rise hoods & no obstruction for
overhead material movement.
- Acid fumes are condensed with in the system.
- Low power requirements.
- Overall a very cost effective answer to all continuous pickling
About FumeLess Pickling
The Shivas Fumeless Acid
Turbulent Pickling System eliminates the need for a Scrubber. In any
pickling system with a scrubber, there is the possibility of escaping acid
fumes due to such factors as:
|Acid Over Temperature
||High Acid Concentration
|Incorrect Water Tray Depth
||Incorrect Fan Pressure or Capacity within the
factors can be caused either by operator error or equipment malfunction. The
release of acid fumes can result in building and property damage and more
importantly environmental code violations.
Fumeless Acid Turbulent Pickling System eliminates all fume concerns.
fumeless acid turbulent pickling system is designed to introduce an
hydraulic jump of acid counter flow against the direction of wire. This
unique technology increases the effectiveness of the pickling acid by
effectively disturbing the laminar flow layer, which normally surrounds the
wire in a static acid pickle and reduces the length of pickling bath.
the introduction of an active turbulent component into the cleaning system,
the "shivas" fumeless acid turbulent pickle can be designed to
offer the following improvements over static acid pickle systems and other
closed systems :
|Shorter pickle length
||Greater cleaning effectiveness
||Greater cleaning efficiency
|Greater possible wire speeds
||Reduced tank cleaning time
Fumeless Acid Turbulent Pickling System disturbs the laminar flow around the
wires and allows the highest concentration of acid to work on the wire scale
overall cleaning system consists of three separate tanks
- A water quench tank
- A fumeless pickling tank
- Complete with water curtain section
- Acid section
- Three (3) rinse sections
- A flux tank.
rinse section follows directly after the acid turbulent cleaning section.
This flood weir and water curtain section ensures that the wire is cleaned
of acid and that the system is fume sealed at the exit end. Fresh water is
added to the last tank of the three (3) rinse tanks on a constant basis at a
rate of approximately 15 liters Per Minute through a ball valve in the fresh
water line The water from the last rinse tank will overflow into the second
tank which, in turn, will overflow into the first tank. The first tank will
overflow into water curtain reservoir and then to drain and /or to the
