Description of reference numerals is as follows:
1-resin holds unit, 2-acid solution tank, 3-alkali liquid tank, 4-acid solution pipe, 5-alkali liquor pipe, 6-fluid pump, 7-drainpipe and 8-fluid cushion container.
Detailed description of the invention
Hereinafter, online form ion exchange resin regenerating unit of the present utility model will be described in detail in conjunction with exemplary embodiment and accompanying drawing thereof.
As shown in Figure 1, in an exemplary embodiment of the present utility model, online form ion exchange resin regenerating unit comprises: resin holds unit 1, acid solution memory cell 2, alkali lye memory cell 3, acid solution pipe 4, alkali liquor pipe 5, fluid pump 6, drainpipe 7, fluid cushion container 8 and rinse water feed unit (not shown).
Wherein, it can be tank body or a body with entrance and exit that resin holds unit (such as, resin cartridge), is contained with hydrogen type cation exchange resin in this tank body or body.Such as, resin holds unit can be the pitch tube of hydrogen conductivity measuring instrument.Resin holds the vertical setting of unit, namely with its entrance be positioned at top and its outlet below mode arrange.
Store acid soak in acid solution storage element, it has acid solution outlet.Such as, acid solution storage element can for storing the acid solution tank of acidic liquid.Acidic liquid in acid solution tank can be watery hydrochloric acid (HCl) solution, such as, can be the HCl solution of 5%.
Alkali storage element memory contains alkaline soak, and it has alkali lye outlet.Such as, alkali storage unit can for storing the alkali liquid tank of akaline liquid.Akaline liquid in alkali liquid tank can be sig water (as NaOH solution), such as, can be the NaOH solution of 2%.
The entrance that the outlet of the acid solution of acid solution storage element and resin hold unit is communicated with by acid solution pipe, thus the acid soak in acid solution storage element can be held unit to resin and provide.The entrance that the outlet of the alkali lye of alkali storage unit and resin hold unit is communicated with by alkali liquor pipe, thus the alkaline soak in alkali storage unit can be held unit to resin and provide.Discharging tube and resin hold the outlet of unit, to discharge soaking the acid soak of hydrogen type cation exchange resin or alkaline soak or rinse water.In addition, online form ion exchange resin regenerating unit also can comprise the waste liquid barrel for containing acid pickle or the spent lye of discharging in discharging tube.
Fluid cushion container to be arranged on acid solution pipe and/or alkali liquor pipe and to be positioned at resin and holds on the entrance of unit.Fluid cushion container can enter before resin holds unit at acid soak or alkaline soak, plays cushioning effect to fluid.Rinse water feed unit and fluid cushion reservoir to fluid cushion supply for receptacles rinse water, the resin that rinse water is used for cleaning resin holds in unit cleans.
Fluid pump 6 (such as, vavuum pump) is arranged on acid solution pipe and/or alkali liquor pipe, and fluid pump is positioned at fluid cushion vessels upstream.That is, fluid pump is between fluid cushion container and acid solution memory cell or alkali lye memory cell.
In addition, as shown in Figure 1, the tract of alkali liquor pipe and the tract of acid solution pipe can merge into same pipeline by triple valve.
The online hydrogen type cation exchange resin regenerating unit of this exemplary embodiment can be used for carrying out regeneration process to new hydrogen type cation exchange resin; Also may be used for the hydrogen type cation exchange resin after to inefficacy and carry out regeneration process.
The process new hydrogen type cation exchange resin being carried out regenerating to process can be: pending resin is loaded resin and holds in unit by (1), with low discharge flushing water, the resin that resin holds in unit is rinsed, in production of resins process, the impurity be mixed in the surplus materials of reaction and manufacture process is not participated in, till backwash is limpid with draining with removing.(2) soak resin 4 hours with the HCl solution of 5%, then rinse to neutral, to remove the inorganic impurity in resin with flushing water.(3) soak resin 4 hours by the NaOH solution of 2%, bleed off alkali lye afterflush resin to draining close to neutral, to remove the organic matter in resin.
Process hydrogen type cation exchange resin after inefficacy being carried out regenerating to process can be: rinsed well by resin flushing water, then soaks clean resin 4 hours with the hydrochloric acid solution of 5%, is rinsed well by resin rear for subsequent use with pure water.
Preferably should note following item when regenerating: A, new resin should be avoided it dewater before pre-processing, otherwise not directly process it, for the new resin normally do not dewatered can directly colourless to draining with water flushing, carry out pretreatment again without after hardness.The volume of B, soak generally gets 2 times to the volume of resin, in the hope of fully being soaked by resin.C, for marginally changing resin, can to carry out in outside anticorrosion container, not pretreated new resin should be avoided directly to dose in interchanger.D, for carrying out the pretreated interchanger of new resin, before regeneration, must big reverse washing be carried out, and should small reverse washing be carried out before big reverse washing.
