It sets.
Background technique
Boiler water process mainly include make-up water (i.e. the supplement water of boiler) processing, condensed water (i.e. steam turbine condensed water or
The condensed water of process flow recycling) processing, 4 parts of feedwater deaeration, water supply ammonification and water treatment processing.Desalination in boiler water
The reason is that with the continuous improvement of boiler parameter and the appearance of direct current cooker, or even require salinity all in boiler feedwater all
It eliminates.At this moment the method that must just use desalination.Ion-exchanger various types used by chemical deionization, use are most common
It is cation exchange resin and anion exchange resin, abbreviation " positive resin " and " negative resin ".In ion-exchanger, brackish water
When flowing through resin, in salinity cation and anion respectively in resin cation (H+) and anion (OH-) become
It is removed after changing.When the basicity of water is higher, in order to mitigate the burden of anion exchanger, the economy of system operation is improved,
Generally require series connection decarbonizer to remove carbon dioxide after cation exchanger.The extra high water of salt content, can also adopt
With reverse osmosis or electrodialysis process, first desalinate water quality, enters back into ion-exchanger and carry out deep desalting.To drum more than high pressure
Boiler or direct current cooker, it is necessary to remove the Trace Silicon in water supply；In, low-pressure boiler then press content situation processing.
Boiler water treatment system generally uses the level-one desalination floating bed method of operation, according to zwitterion in yin and yang resin and water
Exchange reaction principle, the exchange of cation resin exchange bed are to generate strong mineral acid, and mineral acid can ionize out hydrogen ion, this anti-
Ion will affect exchange of the H-type resin to sodium ion in water, it is also possible to remaining sodium-ion type resin carried out from regeneration, so
Cation resin exchange bed water outlet always contains a certain amount of sodium ion, and the sodium ion leaked through causes resin anion (R.A.) to exchange bed again
Water outlet contains sodium hydroxide, and highly basic can ionize out hydroxyl, and this counter ion will affect exchange of the hydroxyl resin to silicate again,
