Shut-Down
If the scrubber is to be shut-down for inspection, cleaning, or for any other reason the
sump should be flushed with fresh water several times to remove any chemical residues.
The make-up water should be isolated and the sump drained through the drain valve. The
pump should not be allowed to run dry.
The lid of the scrubber can then be removed and any remaining deposited solids
removed.
6.
Maintenance
Other than the maintenance of the pump, refer to appendix 2, the scrubber will need little
regular maintenance.
The internal assembly is simple and strip down for inspection straight forward.
•
Turn off and drain the scrubber tank.
•
Remove the recirculation pipe by splitting the unions at the venturi and above the
pump.
•
Unbolt the two pairs of metal flanges and remove the venturi.
•
Unbolt the tank lid and lift out.
•
Lift out the upper mist eliminator grid and eliminator pad.
•
Re-assembly is reverse of removal – carefully ease the inlet pipe through the
eliminator pad.
The unit should be regularly checked for leaks and these should be rectified immediately.
Inspect the internals on an regular basis to check for any damage or deterioration.
Should the spray nozzle become blocked it is removed by unbolting the flanges above
and below the venturi, disconnecting the recirculation pipe and removing the venturi
assembly. The nozzle is unscrewed using a box or basin spanner from the lower end of
the venturi throat.
