|
OPERATING PRINCIPLE |
|
The feed water (1) enters
the plant after being pre-heated
in counter-flow by the
distillate in the exchanger (2),
by the concentrate in the
exchanger (3) and by the
incondensable gases in the
exchanger (4). Then it passes
through the evaporation column
tube side and is maintained at a
constant regulated level (6).
The steam coil (5) or the
electrical heating element (6)
provides the energy to bring the
water to the boiling point. The
pure steam produced is aspirated
by the compressor (7) and
compressed outside the
condenser tubes (8) where it
condenses as distilled water and
releases its latent heat. The
distilled water is recovered in
the hydrostatic column (9) and
conveyed by pump (10) into the
exchanger (2) where it releases
its sensible heat and exits
under pressure (11) The
concentrate is conveyed by pump
(12) to the exchanger (3) where
it releases its sensible heat to
the feed water.

The
incondensable gases which are
released in the hydrostatic
column are sent to the vent
condenser(4) where they release
their sensible heat to the feed
water. |
|
MAIN COMPONENTS
|
-
Evaporation column with shell
and tube condenser, the large
diameter allows the pure steam
decontamination by simple
gravity. |
|
-
High efficiency volumetric
compressor. |
|
-
Sanitary plate heat exchargers
to recover the sensible heat of
distilled water and concentrate. |
|
-
Hydrostatic column for degassing. |
|
-
Sanitary double tube sheet heat
exchanger to recover the
sensible heat of incondensable
gases |
|
-
Distilled water sanitary
pressurizing pump. |
|
-
Concentrate pump. |
|
-
Sanitary diverting valves on WFI
outlet to discharge the
distilled water in case of high
conductivity. |
|
-
Sample port on WFI outlet. |
|
CONTROL SYSTEM
The Control panel is provided with a
PLC and operator interface terminal.
For industrial stills the operations
are completely automatic with the
following features: |
|
-
Function either by weekly timer
or by level of storage tank |
|
-
Function by level of storage
tank only |
|
-
Regulation system for warm
stand-by of the unit |
|
-
WFI conductivity control with
alarms |
|
-
Sanititazion of the plant at
each start |
