Abstract

Both a counter-current regeneration fixed bed and a floating bed ion exchanger fail to thoroughly solve the problem of resin random layer. The utility model is composed of two cylinders with different diameters and coincident axial centers, and water distributing devices which are totally arranged at the upper part in the cylinders, wherein, the distance between the lower end of an inner cylinder and the lower seal head of an outer cylinder is 1/4 the diameter of the inner cylinder. The operation procedure has nothing but running, minor back wash, regeneration, replacement cleaning, and conventional wash. Since the utility model is equivalent to the structural characteristic of a U-shaped communicating device and the property of resin fluidization so that the resin presents a moving or motionless piston form in the operation process without translocation or random layer. The utility model has the advantages of convenient operation, convenient maintenance, low exchanger height, and properly low workshop.

Description

Telescopic ion-exchanger

Telescopic ion-exchanger is a kind of water treatment facilities that ion-exchange is carried out in aspects such as water demineralization, desalination, chemical industry, medicine that are used for.

Be used for the countercurrent regenerating fixed bed ion-exchanger of water treatment, regenerated liquid enters from the ion-exchanger bottom during regeneration, the top discharging.The random layer of resin has been taked low flow velocity regeneration or roof pressure measure in order to prevent to regenerate.But regenerative operation is improper, and resin is layer disorderly.And the random layer of resin rises effluent quality reduction, cycle of operation shortening, regenerative agent consumption and the auxiliary water ratio of ion-exchanger, has also increased the weight of environmental pollution.Countercurrent regenerating fixed bed will carry out big reverse washing to resin behind the operation some cycles.Big reverse washing has destroyed the distribution of resin bed.Floating bed ion exchanger former water of when operation enters from the bottom, and flow out on top, and when the flow velocity of water is low to can not holding up resin, but can make the resin fluidization time, resin also can be disorderly layer.Floating bed ion exchanger will be cleaned resin behind the operation some cycles, the resin level is thoroughly destroyed.

The purpose of this utility model is to solve countercurrent regenerating fixed bed, the floating bed ion exchanger disorderly layer problem of the resin that thoroughly solves of failing.

The purpose of this utility model is achieved in that with two different upright cylinder and water-locators of diameter and is assembled into ion-exchanger.Make two cylinder axis coincidings, it is long-pending that the cross-sectional area of inner core equals interlayer between the inner/outer tube (hereinafter to be referred as " interlayer ") circular cylindrical cross-section, and inner core lower end and low head distance are 1/4 of inner diameter of steel flue, and water-locator is the top in ion-exchanger all.The utility model is because there are two cylinders that are nested together, so be telescopic ion-exchanger.

Telescopic ion-exchanger is made up of inner core water-locator (1), urceolus water-locator (2), small reverse washing water-locator (3), inner core (4) and urceolus (5).Water-locator (1), (2), (3) are the top in interchanger [Fig. 1] all.

Operating procedure has: operation, small reverse washing, regeneration, displacement are cleaned and are just being washed.

Former water entered interlayer by urceolus water-locator (2) when 1. operation moved, and through inner core lower end baffling upwards, flowed out from inner core water-locator (1) downwards.It is out of service when resin lost efficacy.2. the small reverse washing clear water is entered by small reverse washing water-locator (3), cleans the suspension in the upper strata resin bed in the interlayer, discharges from urceolus water-locator (2).3. the resin after regeneration regeneration was lost efficacy makes it recover exchange capacity.Regenerated liquid is entered by inner core water-locator (1) during regeneration, upwards enters interlayer through inner core lower end baffling downwards, discharges from urceolus water-locator (2).4. displacement is cleaned the displacement water for cleaning and is entered inner core by inner core water-locator (1), upwards enters interlayer through inner core lower end baffling downwards, discharges from urceolus water-locator (2), washes out waste regeneration liquid.5. just washing former water and entering interlayer, upwards entering inner core through inner core lower end baffling downwards, discharging from inner core water-locator (1) by urceolus water-locator (2).Just washing and putting into operation after qualified or standby.

The design feature that is similar to the U-shaped linker according to fluidization character and the utility model of resin makes the utility model resin in operating process be that piston-like moves or is static, can not transposition random layer.Respectively the suspension that is deep into inner core and the fine suspension below the resin of interlayer top layer and accumulate in the resin bed of top layer is being played cleaning action in the process of water inlet and regenerated liquid the other way around repeatedly, resin at inner core lower end baffling has been played scrubbing action, so do not need resin is carried out big reverse washing or scouring, thoroughly solved disorderly layer problem of resin.Suspension content in the water is required and can relax.The interchanger height is low, floor space is little, and water-locator all overhauls at the interchanger internal upper part.Simple to operate, the operation flow velocity is changeable, but intermitten service, the not random layer of resin.
