Abstract

The invention discloses a method for secondary transportation of mixed fat in a condensate polishing treatment regeneration system, which includes the following steps: S1. After the cation resin in the cation regeneration tower is acid-regenerated and replaced, the cation resin is converted into a hydrogen-type resin, mixed Some anion resins are transformed into chlorine-type resins; S2, close the No. 4 ball valve, open the No. 1 ball valve, No. 2 ball valve and No. 3 ball valve, start the No. 1 delivery pump, close the other valves, transport for 2 to 4 minutes, and regenerate the anode. The chlorine-type resin in the upper part of the tower is transported to the resin separation tower; S3, continue to transport for 1~3 minutes, and the chlorine-type resin and a small amount of hydrogen-type resin in the upper part of the cation regeneration tower, that is, mixed fat, are sent to the resin separation tower for the second time; S4. Stop the conveying; stop the normal washing; stop discharging the lotion, that is to say, complete the secondary transportation of the mixed fat in the condensate polishing treatment regeneration system. Using the invented secondary delivery method of mixed fat, the mixed fat can be sent to the resin separation tower for the second time, which ensures the regeneration effect of the whole set of resin.

Description

technical field [0001] The invention relates to the field of water treatment methods and equipment, in particular to a method and device for secondary delivery of mixed fat in a condensate polishing treatment regeneration system. Background technique [0002] Condensed water generally refers to the condensed water cooled by circulating cooling water after the steam generated by the boiler does work in the steam turbine. In fact, the condensed water in the hot well of the condenser also includes high-pressure heaters (normal drainage does not reach the hot well), low-pressure heaters and other drainages (drainage refers to the water that enters the heater to heat the feed water and condenses). Due to the inevitable water vapor loss in the thermal system, a certain amount of make-up water (water from the desalinated water tank) needs to be added to the thermal system. Therefore, the condensed water mainly includes: the condensed water after the steam in the steam turbine does...
