Abstract
The utility model relates to an improved water treatment device, which eliminates salt with ion-exchange. The improved water treatment device comprises a water inlet device, a water discharge device, a casing component, a middle discharge device, a weak acid (alkalis) resin layer, a strong acid (alkalis) resin layer, and a positive discharge device which is newly increased. Since the increase of the heights of the positive discharge device and the resin layers, the utilization rate of the space is increased; the periodic water manufacturing quantity of the improved water treatment device is increased; the water usage rate is lowered; the water manufacturing quality is also improved; the cost is lowered, and the operating operation and the maintenance are simple and practical.
Description
The utility model relates to a kind of improved water treating equipment with ion-exchange demineralization.
Double bunk are improved by the original individual layer bed of ion-exchange water treating device, promptly have the two-layer same sex and don't same resin (strong acid/weak acid or highly basic/weak base) carries out combined utilization.Old double bunk have advantages such as alkaline consumption is few, but because two kinds of same sex resin wet true density differences are too little, are difficult to layering preferably, thereby limited the performance of double bunk superiority; Shortcomings such as in addition, old double bunk also have space availability ratio low, and the time of just washing is long.And take the mechanical means separation resin, and need increase peripheral equipment again, make system and complicated operationization, increase investment cost, and the repair and maintenance trouble.Therefore, concerning the individual layer fixed bed unit, limit because of being subjected to the place, in fact mechanical stratified scheme is difficult to carry out.
The purpose of this utility model provides a kind of improved double bunk, can utilize new demixing technology preferably, increases water production in periodic mode, improves the system quality, water saving; And, avoid the shortcoming of mechanical process, reduce cost, operating maintenance is simple and easy to do.
The purpose of this utility model is achieved through the following technical solutions:
A kind of double bunk ion-exchange water treating device comprises into, water-freeing arrangement, housing, intermediate drain installation and strong acid/weak acid resin layer or highly basic/weak base resin layer, and characteristics of the present invention are to be provided with intermediate and positive water-drainage apparatus at resin separation surface place, housing inner chamber middle and lower part.The high 0.4-2.0 rice of strong acid or weak base resin, the high 0.6-2.2 rice of strong acid or strong alkali resin.
Intermediate and positive water-drainage apparatus can be a female pipe tubular type, is installed in the resin boundary of the above 200-2200mm of bottom quartz sand thickness.Pipe leads to outside the housing, is controlled by valve.
Introduce concrete technical scheme of the present utility model (embodiment) below in conjunction with accompanying drawing.
Accompanying drawing Fig. 1 is the primary structure sectional view of the utility model double bunk, and Fig. 2 is a K-K intermediate and positive water-drainage apparatus vertical view.
Wherein: 1-water inlet pipe, the anti-comb of 2-, the 3-distribution device of intaking, the 4-hand-hole, 5-intermediate drain installation, 6-housing, 7-weak acid (alkali) resin layer, 8-intermediate and positive water-drainage apparatus, 9-strong acid (alkali) resin layer, 10-quartz sand thickness, the vaulted porous plate of 11-, 12-advance acid (alkali) liquid pipe, the 13-rising pipe, comb at the bottom of the 14-, the female pipe of row (in just arrange) among the 15-, the 16-arm, the 17-aperture.
Embodiment: cloudy double bunk: specification φ 2500mm.
The double bunk top is provided with water feed apparatus, comprises water inlet pipe 1 and water inlet distribution device 3, and water inlet pipe 1 links to each other with housing 6 interior water inlet distribution devices 3.Housing 6 is for carbon steel is welded, the liner rubber layer.Intermediate drain installation 5 is important component parts of prior art double bunk, is positioned at the about 200mm of the lower face place of weak base resin layer 7 in this novel double-layer bed, and water shoot leads to housing 6 outsides.Weak base resin layer 7 high 1.20m are strong alkali resin layer 9 under it, high 1.90m.Separation surface place between weak base resin layer 7 and strong alkali resin layer 9, (be positioned at quartz sand thickness 10 upwards 2000mm place) is provided with intermediate and positive water-drainage apparatus 8, and this is not available in the double bunk of prior art.In row 5 and in just arranging 8 devices and be a female pipe tubular type, femalely manage 15 and lead to outside the housing 6, arm 16 is managed 15 with mother and is linked to each other, and many apertures 17 are arranged on arm 16 walls.The double bunk bottom is a water-freeing arrangement, comprise vaulted porous plate 11, rising pipe 13 and end comb 14, its vaulted porous plate 11 is provided with quartz sand thickness 10, advance acid (alkali) liquid pipe 12 by the bottom during regeneration and introduce regenerating acid (alkali) liquid, washing fluid can be discharged housing by the anti-comb 2 at top during big bounce.
Enter from the bottom with water purification during general recoil, therefrom arrange 5 or the anti-comb 2 in top discharge.When just washing the water on flushing top can therefrom arrange 5 or end comb 14 discharge.During regeneration, regenerating acid (alkali) liquid advances from the bottom upwards discharges after acid (alkali) liquid pipe 12 enters housing.Regeneration and recoil rear lower resin are cleaner, and after just washing, the upper resin layer is also clean, but the resin of middle part working lining is difficult to obtain cleaning down, and the utility model has added intermediate and positive water-drainage apparatus 8, has just remedied this defective.Adopt the utility model, just arranging in can utilizing and taking substep just to wash, just wash at first for a short time, therefrom arrange 5 after will the flushing of the regeneration waste liquid in the above packed resin layer of middle row to discharge, and then continue the dirtier resin in water inlet flushing middle part, therefrom positive comb is discharged.So just guaranteed the degree of cleaning of middle part resin, can prevent effectively old double bunk clean after still dirtier middle part resin pollute the bottom once more through the clean resin of regenerated, prevented the reduction of regeneration degree.Thereby improved product water quality, also shortened simultaneously and just washed the time that reaches product hydration lattice, saved positive scouring water amount (can save 30%); Also simplified operation, made maintenance easier.In addition, because the unique design of the utility model resin layer height thickens the resin working lining, can improve the space availability ratio of double bunk, thereby reduce equipment manufacturing cost.From original 57.8%, bring up to 68.5% as the space availability ratio of the utility model embodiment.When using identical equipment, adopt the utility model can improve the equipment periodic system water yield, reduce auxiliary water ratio.The system water yield can improve 20-80%.
Because innovative design of the present utility model makes new double bunk keep good switching performance, can utilize new demixing technology to increase water production in periodic mode, and improve the system quality, also reduced auxiliary water ratio, saved water.In addition, also reduced cost compared with mechanical process, operation is easy, and maintenance is easily gone.
