Description
Technical field
The invention belongs to water-treatment technology field, more particularly to tree in a kind of condensate polishing treatment regenerative system sun regenerator
Fat output system and method.
Background technology
Thermal power plant requires strictly water and steam quality, to ensure that condensate polishing treatment is arranged in water and steam quality, water-steam system
Demineralization plant purifies condensed water, and precision processing demineralization plant can remove the pollutions such as foreign ion and TOC in condensed water
Object improves condensed water purity, it is ensured that water and steam quality.If in precision processing demineralization plant after efficiency lost resin, desalination ability declines,
It needs to carry out regeneration treatment, being delivered to mixed bed after resin regeneration qualification continues to run with.
Thermal power plant condensate polishing treatment regenerative system common at present is divided into high tower regenerative system and cone bucket regeneration system
System.Resin output technique is " Hydraulic transportation-pipe flushing " in cone bucket regenerative system sun regenerator, and flushing water is from mixed bed when conveying
Bottom enters mixed bed so that the resin near the water cap of regenerator bottom can not be exported and be remained in positive regenerator.It is remaining
Contain negative resin in resin, the cross contamination of resin is caused in regenerative process next time so that degree of percent regeneration of resin reduces, and influences
Mixed -bed effluent quality, it is therefore desirable to ensure that the resin in positive regenerator thoroughly exports.
Resin output technique has a disadvantage that in cone bucket regenerative system sun regenerator at present：
Using " Hydraulic transportation " technique, bottom water cap resin nearby can not be loosened, resin output is caused to be not thorough.Such as to use up
Amount improves resin transfer rate, it is necessary to extend time of delivery, water consume is caused to increase.The cone bucket regenerative system sun of 600MW units is again
The flow of flushing water is 60t/h in raw tower resin output technique, extends 20 minutes time of deliveries, then more water loss are 20t.
