[summary] equipment
yin, yang and mixed ion exchanger (mixed bed) is used for the primary waterfurther refining. general settings in the anion and cation exchange, also can be arranged in series used in the electrodialysis and reverse osmosis, up to the effluent quality silica containing ≤ 0.02 mg / l, the conductive degree ≤ 0.02us/cm.high pure water after treatment for high pressure boiler, electronic, pharmaceutical,paper making, chemical and petroleum industries etc..
working principle.
mixed bed ion exchange method, is placed in the same exchanger anion, cation exchange resin, mixing them, so can be considered as a myriad of yin, yangexchange multi-stage type resin staggered double bed. the water contains salt, yinyang through the exchanger, is resin exchange, and obtain high purity water.
in the mixed bed, due to yin, yang resin are uniform, so the exchange of cations and anions, almost at the same time reaction. or, cation exchange water and anion exchange is multiple interleaved. the h exchange with the h and oh are notaccumulated, basically eliminates the influence of the counter ion, exchange ofthorough.
the mixed bed regeneration method using in vivo. regeneration using two differentresin proportion, with backwashing overcast, cation exchange separation of resin,resin deposition in the next, the anion resin and cation resin floating on top, with hydrochloric acid (sulfuric acid) regeneration, regeneration of anion resin with caustic soda.

1 water inlet device:
a water distribution device at the upper part of the inlet in the exchanger, uniformdistribution.
2 regeneration device:
liquid inlet pipe is arranged above the anion exchange resin, open a small holefluid pipe, tube coated stainless steel trapezoidal wire. anion exchange resin is regenerated with alkali solution from the liquid inlet pipe into the. regeneration of cation exchange resin with acid into the bottom drainage device, regenerated acidalkali wastewater are discharged from the discharge, mouth.
the 3 ranked device:
discharge device is arranged on the interface of yin, yang resin, used forregeneration of acid, alkali waste excretion and washing liquid, type of branch pipetype, hole pipe coated with trapezoidal stainless steel wire.
4 drainage device:
using porous plate is arranged on the drainage cap, porous plate with steel liningrubber.
in addition, in the yin, yang resin interface, resin surface and maximum backwashexpansion height is provided as the endoscope is a, to observe the surface of the resin and the backwashing resin.
the upper part of the cylinder body is provided with a resin inlet, to the lower part of the cylinder near the perforated plate is arranged at the resin discharge outlet,the resin input and unloading by water transport may.
