In the high velocity mixed bed treatment system, the regenerative cation and anion resin having high exchange capacity are mixed thoroughly with a certain proportion. Then they are put into the in extraneous regenerative high velocity mixed bed to carry on demineralization treatment.
The high-rate mixed bed system of this project has 2×50% treatment capacity. When one exchanger loses efficiency, it will open the 50% bypass automatically, and it will be put into operation again after it has being regenerated. When the pressure difference or water inlet temperature of the mixed bed main pipe is beyond the standard, the 100% bypass will be opened automatically.
For the condensate treatment of this project, one unit is allocated one set of high velocity system, and the resin extraneous regeneration system is communal. Every set of high velocity system is made up of 2 DN2200 extraneous regeneration high-velocity mixed beds and 2 recycle pumps. Resin extraneous regeneration system is mainly made up of resin separation equipment, resin regeneration equipment and electric heating water tank.
System operating mode:
There are two bypasses opened and closed automatically in condensate polishing system (beside regeneration bypass and super temperature super pressure bypass). The capacity of regeneration bypass is 50% of the condensing capacity, and the capacity of regeneration bypass and super temperature super pressure bypass is 100% of the condensate capacity.
When the water outlet conductivity or silica of the condensate polishing mixed bed is over the specified value, the equipment stop and step out, and the regeneration bypass is placed in operation.
When the water inlet temperature of condensate polishing is more than 55℃ or the pressure difference of mixed bed inlet and outlet is over 0.35MPa, all operation unit of the mixed bed stop, and the super temperature super pressure bypass is placed in operation.
The failure resin of stopped mixed bed is sent to regeneration system to be air scrubbing, to be separated, and to be regenerated. Send the regenerated standby resin inside the resin storage tank to high velocity mixed bed.
The startup of mixed bed, shutdown of mixed bed, resin transmission, resin regeneration of condensate polishing system can all be carried on automatically.
