Description

Ion exchanger

The utility model discloses a kind of ion-exchanger, belong to the water treatment facilities field.

At present, ion-exchanger has polytype, main adopt fixed-bed ion exchanger, thermopnore ion-exchanger and floating bed formula ion-exchanger arranged, wherein, floating bed formula ion-exchanger has many advantages, but, when backwash, because its expansion space is little, big reverse washing need be provided with special syringe, cause the construction cost height, complicated operation.

The purpose of this utility model provides a kind of novel ion-exchanger, and it has and need not special syringe is set, and is simple to operate, the characteristics that construction cost is low.

The purpose of this utility model is achieved in that a kind of ion-exchanger, it is made up of housing, import, outlet, last porous plate, following porous plate, regenerated liquid distributor, ion exchange resin, last porous plate, regenerated liquid distributor place in the housing upper cavity, following porous plate places in the lower housing portion cavity, between porous plate, import was in lower housing portion about ion exchange resin was contained in, and outlet is on housing top, wherein, the housing middle part has and gives a water inlet.

Wherein, housing is to go up greatly, descend the reducing cylinder body structure little, that the middle part is progressive;

Wherein, water-locator is equipped with at progressive body place, housing middle part;

Wherein, have charging aperture and discharging opening on the housing.

The utility model has the advantages that: give a water inlet because the middle part of ion-exchanger housing has, prevented the appearance of resin random layer phenomenon when becoming bed, the sufficient resin of guaranteeing to regenerate can enter the top of floating bed; That housing adopt to be gone up is big, little, reducing cylinder body structure that the middle part is progressive down, has changed the one-tenth bed mechanism of present floating bed formula ion-exchanger, and it is when passing ion-exchanger by fluid, in different barrel dliameters, the characteristics that flow velocity is different hold up ion exchange resin, the formation floating bed; During running status, the resin overwhelming majority in the small diameter portion of bottom is rushed out, and enters top, forms enough thick floating bed, has guaranteed the effect of ion-exchange; During shut down condition, a part of resin is got back in the minor diameter tube, makes the top major diameter that enough spaces partly be arranged, usefulness for the expansion of backwash resin has realized that ion exchange resin can carry out abundant backwash in operational outfit, cancelled special-purpose backwash device, reduced construction cost, and simple to operate; Simultaneously, give a water inlet can also doublely do the backwash water inlet; In addition, when regenerated liquid flow into the bottom minor diameter by the top major diameter, the regenerated liquid utilization was more abundant, and discharge opeing concentration is low.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a running status schematic diagram of the present utility model;

Below in conjunction with accompanying drawing the utility model is done further to discuss in detail:

Embodiment 1:

A kind of ion-exchanger, it by housing 5, import 4, outlet 1, give a water inlet 9, charging aperture 2, discharging opening 3, go up porous plate 6, porous plate 12, ion exchange resin 7, water-locator 8, regenerated liquid distributor 11 are formed down;

Housing 5 is to go up greatly, descend the reducing cylinder body structure little, that the middle part is progressive, the diameter ratio of major diameter and minor diameter, be proportion, conditional decision such as operation flow velocity etc. according to institute's spent ion exchange resin, the utility model major diameter can be selected 3.2 meters～0.8 meter for use, minor diameter can be selected 0.4 meter～2.8 meters for use, the conical surface at reducing place and the angle of cylindrical shell can be selected 30 °～45 ° for use, and the height of upper and lower cylindrical shell can be according to the length of the cycle of operation and water quality and selected arbitrarily; The present embodiment major diameter is selected 2.0 meters, and minor diameter selects 1.4 meters, and the height of top cylindrical shell selects 4 meters, and the height of bottom cylindrical shell selects 2.6 meters, and the conical surface at reducing place and the angle of cylindrical shell are selected 45 ° for use, and present embodiment is selected strong acid cation resin for use, and consumption is 12.1 cubic metres;

Import 4 is in housing 5 bottoms, outlet 1 is on housing 5 tops, give an import 9 at housing 5 middle parts, have charging aperture 2 on housing 5 tops, the bottom has discharging opening 3, in last porous plate 6 and regenerated liquid distributor 11 fixed installation housings 5 upper cavity, on the last porous plate 6 water cap 10 is housed, following porous plate 12 fixed installation housings 5 bottoms, water cap 10 also is housed on it, ion exchange resin 7 is contained in 12 of porous plate 6 and following porous plates, and water-locator 8 is weldingly fixed on by supporting leg in the middle cavities of housing 5 according to conventional method;

Wherein, it is water inlet that import 4 is connected to three the tunnel, the one tunnel,, water intaking valve A1 is housed on it, another road is the regenerated liquid outlet, and regenerated liquid dump valve A8 is housed on it, the one tunnel is just to wash discharge outlet again, is equipped with on it and just washes draining valve A9; To be connected to three the tunnel, the one tunnel be delivery port in outlet 1, outlet valve A4 is housed on it, another road is a discharge outlet, draining valve A5 is housed on it, the one tunnel is just to wash import again, and Valve for washing A3 is housed on it; But give a water inlet 9 double as backwash water inlets, be equipped with on it and give a valve A2; Charging aperture 2 also connects two-way, and one the tunnel is the regenerated liquid import, regenerated liquid inlet valve A7, another road are housed are anti-row mouthful on it, and backwash draining valve A6 is housed on it; Bleeder valve A10 is housed on the discharging opening 3.
