Description

A kind of water softening device

Technical field

The utility model relates to a kind of device that utilizes the resin softening water, belongs to the water treating equipment technical field.

Background technology

In water treating equipment commonly used, all have the preparation storage vessel of regenerant solution, regenerant solution mostly is sodium chloride aqueous solution, and common preparation storage vessel mostly is cement pit.The blending process of solution is comparatively simple, and its method is that solid particle of sodium chloride is put into cement pit, and being dissolved in water then gets final product.But discovery is in operation: 1. inhomogeneous with the concentration of salt solution of this container and method acquisition, this can directly have influence on the regeneration effect of ion-exchanger; 2. the container of constructing with cement is influential to salts solution; 3. the impurity that is deposited at the bottom of the pond is not easy to remove.In addition, in this water treating equipment, its ion-exchange jar is except bearing the task that softening water is provided, and the regeneration of its ion-exchanger is also carried out in jar, therefore, around tank body many valves can be set, and makes this device seem too complicated numerous and disorderly.

Summary of the invention

Provide a kind of improved water softening device thereby the utility model is used to overcome the defective of prior art, the regenerant solution concentration that this device makes preparation evenly, favorable regeneration effect.

It is as follows to solve the problems of the technologies described above the technical scheme that is adopted:

A kind of water softening device, it comprises ion-exchange jar and regenerant solution case, and the regenerant solution case is made of casing 14 and regenerator storage tank 11, and regenerator storage tank 11 is sleeved on the top of casing 14, and its bottom land is provided with filter screen 12.

Above-mentioned water softening device, the aperture of said filter screen 12 are Φ 1-Φ 5mm.

Above-mentioned water softening device, said regenerator storage tank 11 perisporiums are provided with filter opening.

Above-mentioned a kind of water softening device, the volume of said casing 14 are the 30-2000 liter.

Water softening device provided by the utility model, its regenerant solution case adopt solute last, solvent under frame mode, can make solute dissolving gradually under solvent soaking like this, and because of solution proportion spreads solution downwards greater than solvent, thereby the uniform regenerant solution of concentration obtained.Regenerate with it, effect can be better.In addition, a jar mouthful place adopts novel compound reversing valve (as disclosed technical products among the Chinese patent ZL02257746.7) to replace original a plurality of common valves on the ion-exchange jar of the present utility model, can make whole plant become compact. simple in structure, can significantly reduce the device fabrication cost, and convenient and reliable operation becomes more satisfactory water softening device.This device can be made series product according to user's needs, and the output of softening water is from 0.5T/h～20T/h.

Description of drawings

Fig. 1 is a kind of embodiment synoptic diagram of the utility model.

Each label is among the figure: 1. ion-exchange jar, 2. ion exchange layer, 3. pipe core, 4. waste pipe, 5. manually operated directional valve, 6. soft water outlet, 7. liquid case water compensating valve, 8. water service pipe, 9. regeneration valve, 10. feedwater valve, 11. the regenerator storage tank, 12. filter screens, 13. salt liquid pumps, 14. casings.

Embodiment

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Referring to accompanying drawing, regenerant solution case of the present utility model is made of casing 14 and regenerator storage tank 11.Casing 14 and storage tank 11 all adopt the moulding of organic polymer material time processing, and macromolecular material can adopt the PE material.Regenerator storage tank 11 is sleeved on the top of casing 14, the wall and the bottom of storage tank 11 are contained in the casing 14, like this, solvent just can be immersed in the storage tank by the filter screen 12 (so-called filter screen is exactly the uniform filter opening of bottom land in fact) of storage tank 11, makes the regenerator solute be dissolved as solution.Solvent preferably adopts softening water.

The size of casing 14 should be selected according to the size of the ion-exchange jar of its configuration, and the size of casing 14 is generally selected between the 30-2000 liter capacity.The pore size of being located at the filter screen 12 of storage tank 11 bottoms or wall should be looked the size of the regenerator solid particulate that is adopted and determine that generally its hole should be selected between Φ 1-5mm.

The workflow of this water softening device is described as follows:

Normal operation: hard water enters in the ion-exchange jar 1 through feedwater valve 10, water service pipe 8, manually operated directional valve 5, is softened during hard water process ion exchange layer 2, discharges through pipe core 3, reversing valve 5, soft water outlet from the bottom to top then.

Backwash: when the soft water of discharging is defective, carry out this program and program afterwards thereof.In this program, at first reversing valve operated 5, hard water is entered in the ion-exchange jar 1 in pipe core 3 through reversing valve 5 from top to bottom along water pipe 8, the water in entering jar from bottom to top through ion exchange layer 2 and reversing valve 5 after from waste pipe 4 discharges.In this process, the resin ion-exchanger is rinsed, and impurity is rushed out, and makes resin loosening, is commonly called as the pine bed.

Regenerant solution preparation: earlier quantitative solid NaCl is put into regenerator storage tank 11, open feedwater valve 10 and liquor box water compensating valve 7, after making the extremely suitable height of water level in the casing 14, close liquor box water compensating valve 7, the NaCl in the storage tank 14 are dissolving automatically in one hour.

Regeneration: start salt liquid pump 13, regenerant solution is from top to bottom entered in the ion-exchange jar 1 in pipe core 3 through regeneration valve 9, water service pipe 8, reversing valve 5, enter into jar interior regenerant solution from the bottom to top by resin ion exchange layer 2, discharge from waste pipe 4 through reversing valve 5 afterwards, through after the regenerative process, the resin ion excretes adsorbed a large amount of calcium, magnesium ion, has regained the adsorptive power to calcium, magnesium ion.

Displacement: rotate feedwater valve 10 (half-open), feedwater is from top to bottom slowly entered in the ion-exchange jar 1 through reversing valve and through pipe core 3.Enter into jar 1 interior water and pass through from the bottom to top after the ion exchange layer 2, discharge from waste pipe 4 through reversing valve 5, the purpose of this program is that the abraum salt liquid of keeping somewhere in ion-exchange jar 1 is discharged from outside the jar.

Just wash: reversing valve operated 5, and thoroughly open feedwater valve 10, make feedwater through reversing valve 5 and enter in the ion-exchange jar 1 from top to bottom, through behind the ion exchange layer 2, behind pipe core 3 and reversing valve 5, discharge from bottom to up from waste pipe 4.In this course, remaining salinity is also discharged by cleaning down in the resin ion exchange layer 2.Afterwards, can enter into the normal operating condition of next cycle.
