Embodiment Construction

[0022] In conjunction with the accompanying drawings, the invention scheme is described as follows:

[0023]The spent resin in the mixed bed is connected from the bottom of the mixed bed 15 through the pipeline and the inlet valve 1 of the resin separation tank 11, and then transported to the resin separation tank 11 (the first tower, using the patent No. ZL 20052070245.8 equipment), scrubbing and separating with water and wind, The resin is layered, the upper part is anion resin, the lower part is a cation resin, the upper anion resin is connected to the anion resin regeneration tank 12 (second tower) through the valve 3 of the pipeline and the resin separation tank 11, and the lower part cation resin is passed through the pipeline, The lower valve 2 of the resin separation tank 11 and the cation resin regeneration valve 5 are sent to the cation resin regeneration tank 13 (the third tower), and the mixed resin layer with incomplete separation between the anion and yang resins ...

Abstract

The invention relates to a four-tower mixed ion exchanger resin external separation regeneration method. Invalid resin is conveyed to a first tower, i.e. a resin separation tank through a pipeline and a valve from the bottom part of the mixed bed, the invalid resin is cleaned and separated by water power and wind power inside the resin separation tank, the cation and the anion resin is layered, the upper anion resin is conveyed to a second tower, i.e. a anion resin regeneration tank through an upper valve and a pipeline, the lower cation resin is conveyed to a third tower, i.e. a cation regeneration tank through a lower valve and a pipeline, the anion resin is regenerated by excessive alkali liquor inside the second tower, the cation resin is regenerated by excessive acid liquor inside the third tower, after the regeneration, all anion resin is changed to an OH type, all cation resin is changed to an H type, and the anion resin and the cation resin are respectively convened to a fourth tower, i.e. a resin storage tank from the second and the third towers. The method solves the mixed-bed resin external separation and regeneration problems of high-parameter industrial boilers and steam generator condensed water deep treatment (condensed water precise processing) in large-capacity fire plants, nuclear power plants and the like.

Description

technical field [0001] The present invention relates to an ultra-large capacity, high-parameter industrial boiler, a method and device for in vitro separation and regeneration of condensate polishing treatment mixed bed resin in industrial boilers and steam generators. Power plants, nuclear power plants and other high-parameter industrial boilers, steam generator condensate polishing requirements, with the characteristics of energy saving, water saving, saving acid consumption, alkali consumption and fully automatic operation. Background technique [0002] The high-parameter steam of boilers in large-scale thermal power plants and steam generators in nuclear power plants is condensed into condensed water (condensed water) after doing work, which must undergo advanced treatment before it can be recycled. At present, the condensate treatment devices all adopt the ion exchange method, that is, the mixed bed (mixed ion exchanger) is used to conduct advanced treatment of the cond...
