4 Product Description
4.1 Intended Use
The
Easyzon D
on-site chlorine dioxide generation
system is intended for the following purpose: Automatic
generation of a <0.2% diluted chlorine dioxide solution
using sodium chlorite, hydrochloric acid and cool water.
The resulting solution can be used as a disinfection
agent for a wide range of applications.
4.2 Design and Function
The
Easyzon D
is a fully automated batch skid
system, with the output ranging from 100 to 500g/hr
of ClO
2
. The system can be configured with a
standalone reaction vessel to produce 100g/hr, or two
vessels in series to produce 200g/hr. Higher
concentration precursors can be used to gain 250g/hr
and 500g/hr respectively.
The
system
uses a plastic cabinet to mount its
instrumentation and house its reaction vessel
/’s, these
are protected by a cover which can be secured shut
by a padlock on a toggle latch.
Chemical precursors are safely drawn into the reaction
vessel
/’s
[19] at a 1:1 ratio from a drum/tank by the
means of a vacuum created by a venturi [12] . Each
reactant is precisely measured and controlled via
individual flowmeters
[6 & 7] and solenoid valves [8 &
9] , which allow the reaction to
produce a ≈2 wt% ClO
2
solution (Or
≈5 wt% ClO
2
with higher strength
precursors) . A predefined cycle time enables the
system to batch the necessary number of times to
generate the desired g/hr. After a reaction time of 15
minutes the product enters a level-controlled product
tank
[17] . Any excess gas created in the reaction
process passes through the carbon filter [21] and into
the atmosphere. This process continues until
the ‘Tank
F
ull’ level is reached, where the system waits for an
adjustable set time before restarting generation (see
section 8.5.3).
