Abstract
The utility model relates to a self-top-pressure counter flow regenerating ion exchanger. Ion exchange resin which is arranged in a tank body is divided into an upper layer and a lower layer, and the middle of the upper layer and the lower layer is separated by middle water discharging equipment. Regenerating liquor is divided into two channels, one channel flows upward and then flows forward and downwards from the top of the upper layer of resin, the other channel flows downwards and then flows conversely and upwards from the bottom of the lower layer of the resin, and the combination and the regeneration of forward flow and counter flow are carried out. Upper regenerating liquor flow and lower regenerating liquor flow are controlled to flow upwards, and the combination and the regeneration of the forward flow and the counter flow are carried out. The flow quantity Q1 of upper regenerating liquor and the flow quantity Q2 of lower regenerating liquor are controlled, and the relation of Q1/Q2=h1/h2=0.25-0.35 exists among the flow quantity Q1 of the upper regenerating liquor, the flow quantity Q2 of the lower regenerating liquor, the layer height h1 of an upper resin layer and the layer height h2 of a lower resin layer. The utility model and a forward flow regenerating apparatus both have simple structure, convenient operation and little consumption of the regenerating liquor, and the water quality of water discharge achieves the standard of the water quality of counter flow regeneration water discharge.
Description
The utility model relates to a kind of equipment of the ion-exchanger regeneration of losing efficacy.
Ion-exchanger comprises sun (the moon) ion-exchanger of demineralization plant and the Na-ion exchanger of softening equipment.After ion-exchanger lost efficacy, need regenerate, for example to cation exchanger, the reaction equation that adopts Hc1 to regenerate is:
R
2 
＋HCL＝2RH＋
Adopt at present the mode of regeneration that co-current regeneration and counter-current regeneration are arranged, co-current regeneration is that regenerated liquid is flowed downward above the tree layer, though its operation is simple, effluent quality is bad, and therefore regeneration specific consumption height only adopts during good especially or polyphone regeneration at raw water quality.And the counter-current regeneration effluent quality is good, and the regeneration specific consumption is low, so employing is more general.
Counter-current regeneration is from the upwards operation of resin bed bottom, from the water outlet of resin bed top with regenerated liquid.Counter-current regeneration is divided into roof pressure and two kinds of no roof pressure modes again.Adopting the roof pressure mode is to add a compressed air or water with being top pressing system, and establishes a packed resin layer on resin bed top,, occurs disorderly layer system complex, troublesome poeration though it can prevent that resin is loosening.And adopt no roof pressure mode random layer very easily to occur, and plant phenomenon here for anti-, have only the flow velocity of control regenerated liquid, will certainly prolong the recovery time like this.
The purpose of this utility model is the different shortcomings that exist according to above-mentioned various regenerations, be intended to design a kind of following current, the counter-current regeneration mode is the regenerant ions interchanger of one, adopt this capable again ion-exchanger effluent quality good, simple to operate, the regenerated liquid consumption is low.
The purpose of this utility model realizes in the following manner, from roof pressure counter-current regeneration ion parallel operation, is contained in ion exchange resin 4 in the tank body 6 and is divided into upper and lower two-layerly, middle discharge water equipment 5 arranged between two-layer.Middle device for transferring 5 is made up of with the arm 11 that is arranged in person in charge both sides a person in charge 10, has apopore 12 on the arm.Regenerated liquid is divided into two-way through valve 1, and one the tunnel through valve 2, restricting orifice 3, leads to last resin bed top; One the tunnel leads to resin bed bottom down through valve 9, bed course 8 by tank base.Regeneration liquid waste therefrom discharge water equipment arm 11, be responsible for 10, discharge through valve 7.The ratio of upper and lower resin bed floor height h1, h2 equates with the ratio of liquid measure Q1, the Q2 of the upper and lower resin bed regenerated liquid of flowing through, promptly
=
=0.25～0.35
Below in conjunction with description of drawings the utility model content.

With reference to accompanying drawing, open valve 1,2,9,7, regenerated liquid respectively from the top of ion exchange resin and bottom following current and adverse current through exhausted resin, to its regeneration, regeneration liquid waste enters arm 11 from many holes 12, then flows into to emit after being responsible for 10 again.
Key of the present utility model is flow velocity Q1, the Q2 of suitable, counter-current regeneration liquid and determining of upper and lower resin bed floor height h1, h2.According to dynamics of ion exchange and resin swelling water mechanics, for making regeneration specific consumption minimum, and the tree purport does not flow, then can calculate Q1 according to the resistance of resin resistance and water distribution system equates with h1/h2 with the ratio of Q2, then need by restricting orifice 3 controls, i.e. the main regulation flow velocity of restricting orifice through hole 13 of flowing through.The computing formula that the utility model is taked is:
Resin resistance calculation formulae: △ P=0.05
(MPa)
V kinematic viscosity L resin floor height in the formula
Dep resin average diameter ω regenerated liquid flow velocity
Restricting orifice via area computing formula: S=
△ P in the formula
2Restricting orifice is pressure reduction up and down
K constant-get 6.2
According to different resins, through experiment repeatedly, calculate, the utility model is determined
=
=0.25～0.35
Ion exchange resin state after the utility model regeneration as shown in Figure 5, the resin RH of figure empty part 14 after for regeneration gets the resin of part 15 for not being reproduced ready, as seen from the figure, effluent quality is good, can reach the effluent quality of counter-current regeneration equipment.
The utility model is integrated following current, counter-current regeneration, the same with following current equipment, simple in structure, easy to operate, do not need packed resin layer, small investment, and the regenerated liquid consumption is saved about 50%-100% than following current, and effluent quality is much higher than the following current effluent quality, has reached the requirement of counter-current regeneration effluent quality.
