The resin regeneration method of a kind of condensate polishing treatment high tower separation technique regenerative system comprises the following steps:
Step one: resin separation regenerative process
In precision processing mixed bed, exhausted resin is admitted in knockout drum, first carry out primary air scouring, make separated from contaminants heavier on exhausted resin out, knockout drum is discharged with current, then upper cone body portion water is emptied, with the high-velocity flow of 44 ~ 50m/h from knockout drum bottom by resin bed holder to collecting region, top.
Reduce water flow velocity (substantially dividing 46m/h, 23m/h, 12m/h, 6m/h, 3m/h several stage), to positive resin critical dropping velocity, maintain a period of time, most positive resin is made to gather the boundary of cone and direct tube section, reducing water flow velocity again makes positive resin settle down, and forms positive resin layer; Continue to reduce water flow velocity to negative resin critical dropping velocity, maintain a period of time, make negative resin assemble, reduce water flow velocity again, make negative resin settle down, form negative resin layer, finally the flow velocity of backwash water is gradually decrease to zero, makes that anterior resin is old at leisure lowers. (for making resin to settle in order, sedimentation velocity difference controls between 20 ~ 40m/h).

Step 2: the conveying of resin
First carrying negative resin, the delivery port of negative resin is positioned at above hybrid resin bed boundary about 250-500mm place, in order to stay certain positive resin as compound tree lipid layer, it is therefore an objective to prevent from carrying secretly in negative resin positive resin;
Carrying positive resin again, positive resin is sent to sun tank by the positive resin delivery port bottom knockout drum; The same compound tree lipid layer retaining 250-500mm, it is prevented that carry negative resin in positive resin secretly;
Step 3: resin is cleaned, regeneration
After positive resin and negative resin are respectively delivered to sun tank and cloudy tank, intake to resin bed height, air bump rinse operation, impurity is made to separate from resin surface, clean water while continuing to enter from sun tank and cloudy pot bottom captation, make the past rising of water in sun tank and cloudy tank, resin bed expands, when resin bed expands about 50% water level, close sun tank and cloudy tank to idle discharge air valve, thus forming an air chamber having pressure in sun tank and cloudy tank, stop water inlet and air, open Regenerant apparatus valve and sun tank and cloudy pot bottom captation valve simultaneously, due to air chamber quick pressure releasing, impurity and broken resin is made quickly to go out with water. operation is made to may be repeated, until resin is cleaned.
The gap-ratio shredded resin of Regenerant apparatus and underdrain device is big and less than granulate resin, so can discharge broken resin in rinse stage, retain whole resin, can guarantee that again regenerated liquid even into. Structure and rinsing step on this equipment eliminate impurity and broken resin, can prevent the delay of impurity and shredded resin in resin bed from destroying separation process and affecting regeneration effect. Because the precipitative properties of broken positive resin is similar to positive resin, remains in above resin bed when separating, be blended in positive resin, contact alkali during regeneration and be transformed into Na+Type resin, leaks Na in a large number in the mixed bed ammonia type stage after putting into operation+And make mixed bed be not normally functioning, it is greatly shortened cycle of operation.
