BULK BAG/SORBENT DISPENSERS

Our cleanDOSE sorbent dispensing systems are based on dosing reagents using bulk bags.  They all have feeders like the CleanPAC systems, but are larger to accommodate a bulk bag and we have three types:

  • CleanDOSE Base – here the bulk bag is lifted by forklift truck onto a membrane.  The bulk bag bottom spout is opened via a door.  Periodic agitation may be required.
  • CleanDOSE Lid – this version has the capacity to take more than one bulk bag full and has a closing lid.  This is a tidier solution since no further agitation should be needed and it protects the dry powder.  A forklift truck is required to lift the bag.
  • CleanDOSE Lift – this is the same as the lid version but uses an overhead frame and hoist to lift a bulk bag into the dosing hopper.  No forklift is required, only a pallet truck.

These dry powders are usually conveyed into the ducting before the filter system under a negative suction created by the system ID fan, or blown using a smaller fan and lean conveying.

The sorbent feeders can handle all sorbents but our most used sorbents are:

  • Sodium Bicarbonate / Briskarb (Acid gases)
  • Activated Carbon (Heavy metals & dioxins)
  • Pacsocarb (mixture of bicarbonate and carbon)
  • Hydrated Lime (Acid gases)
  • Sorbacal SPS (Acid gases)

Given the system volume and gas composition, we can calculate this in house using our “reagent waste calculator” where we input the gas composition data and this calculates the recommend dosing rates and waste output. In doing this we can recommend the best suited sorbent feeder from any of the above three types, or our cleanPAC “rip and tip” hopper or our cleanSORB silo range.

Our recent Projects

We were contracted to provide 2 small Ceramic filters suitable for a small volume but with a design maximum temperature of 600°C. In addition the filters will be handling a syngas which cannot be mixed with oxygen so an alternative to compressed air would need to be used for the ‘Cleanpulse’ cleaning of the 25 Ceramic element in each of these CPC78 filters. In addition dosing of small amounts of a re-agent is required so the client also opted for a ‘Cleandose’ 25kg bag skid. Find out more about Project CAD below.
