Motor dust extraction

Blower dust extraction

The chemicals are dissolved separately from each other in the dissolving system.
The control valve (44) opens when the starting level in the buffer tank has been
reached. The dissolving water is divided downstream of the motive water pump
(46). The particle stream is ducted via the float regulator valve (32) into the rinsing
tray  (33).  From  there,  it  is  sucked  off  by  the  injector  (35)  together  with  the
chemicals dosed in the rinsing pipe (34). The dissolving cyclone (40) circulates the
calcium hypochlorite granulate until it has completely been dissolved. An optical
sensor (41) detects the chlorine granulate dosed, which can be seen in  the cyclone
shortly after the start of dosing. The controller reports a fault and the dosing is
interrupted  when  no  chlorine  is  measured  8  seconds  after the  start  of  the  2nd
dosing cycle.

The following safety package is installed to ensure that chlorine granulate and acid
cannot mix and react with each other in the open part of the dissolving system:



The dosing of the two chemicals takes place in fixed cycles with pauses between

the dosing steps.

The power supplies of the two dosing motors are interlocked by a relay system
that ensures that

the two motors can never operate at the same time

!



The water supply and the water flow is monitored by pressure switches (31),

level switches (37) and flow switches (39).



Dosing only takes place when the water flow is ensured.



The dosing system is stopped and an appropriate fault message is generated
when a deviation from the set target values occurs.

ATTENTION !
The use of sulphuric acid up to a concentration of 50% is generally
possible. Changes in the dosing performance and/or increased
corrosiveness have to be considered when a higher concentration
