Description

The two chambers of high flow rate ion-exchanger

Affiliated technical field

The utility model belongs to the Water Treatment equipment technical field, relates to a kind of two chambers of high flow rate ion-exchanger water treating equipment that are used for the chemical deionization water treatment.

Background technology

Two chambers fixed bed (abbreviation lifted bed, double) is the novel ion exchange water treatment equipment of development at the beginning of the eighties in last century, its appearance has solved in the past by the double bunk of Japanese's invention and the multinomial defective that is existed by two chambers floating bed that the fritz invents, advantage such as have that effluent characteristics is good, the medicine consumption is low, operation is simple is compared with other class ion-exchanger and to be had clear superiority.Lifted bed, double obtains using comparatively widely in various fields such as electric power, chemical industry, oil, metallurgy, iron and steel at present.

But lifted bed, double yet has the some shortcomings part in actual engineering operation, mainly be that its flow velocity is lower, generally has only 20～30m/h, cause its single system water yield less and occupation area of equipment is bigger, because the operation stream scooter 40m/h of two chambers floating bed, therefore requiring to make under the bigger situation of the water yield, producer can be more prone to select two chambers floating bed, and this will have influence on applying of lifted bed, double undoubtedly.In addition, be filled in the Archon that indoor strong type resin top is used as water distribution under the lifted bed, double in the prior art and adopt the soft Archon of plastics, the regeneration back is because the expansion of strong type resin, the soft Archon compression of plastics is followed the string, regeneration can make down the chamber water subfill occur once more, cause down disorderly floor of chamber resin easily, influence regeneration effect, make the water quality variation of water outlet, cycle reduces with the system water yield, has influenced the performance of lifted bed, double performance, and furthermore the soft Archon of plastics is stronger to the adsorptivity of alkali lye, also make the time of just the washing lengthening of cloudy lifted bed, double, the water consumption increases.

The utility model content

The purpose of this utility model is to overcome the existing in prior technology defective, so provide that a kind of device structure is simple, easy to operate, operation flow velocity height, regenerate at present the chamber resin not disorderly floor, the resin supplementary rate is low, the regenerated liquid consumption is low, effluent quality good, exert oneself greatly, floor space is little, install and debug high flow rate pair chambers ion-exchanger easily.

Be used to realize that the technical solution of foregoing invention purpose is such: the two chambers of the high flow rate that is provided ion-exchanger has the cylinder body of establishing chamber and following chamber in one, porous plate by a band double speed water cap between two Room separates, at last chamber and following indoor weak type resin and the strong type resin that particle diameter is 0.45～1.25mm that be filled with respectively, the resin effective size of grain is 0.60mm, the loading height of last chamber resin is 0.5～2m, the filling of following chamber resin highly is 0.8～2m, total filling of two Room resins highly is 2.5～3.5m, is filled with the inertia duroplasts Archon that the high granularity of 0.2～0.3m is 1.5～2.5mm above the resin of following chamber.

The utility model reduces running resistance for improving the operation flow velocity, has adopted the method that increases resin particle diameter and porosity; In order to prolong the periodic duty time of interchanger, increased resin height; The random floor of resin, reduced water and consumes the time of just washing of the cloudy lifted bed, double of effective simultaneously shortening when the mode of filling inertia duroplasts Archon can prevent to regenerate above the resin of following chamber in addition.Operation flow velocity according to the two chambers of the high flow rate ion-exchanger of above technical scheme development can be up to 45m/h, when device diameters is 3m, single device is exerted oneself and can be reached 315t/h, therefore, when exerting oneself of requiring is identical, compare with existing lifted bed, double, floor space of the present utility model is very little, so promptly make the area of whole factory building reduce, cost reduces, and simultaneously the gross investment of equipment is reduced, and, because the bottom adopts double speed water cap as water-distributing device, equipment installation and debugging work load are greatly reduced, serviceability strengthens.Except that have above-mentioned flow velocity height, big, the advantages such as floor space is little, reduced investment of exerting oneself, the utility model also has regenerate at present chamber resin not disorderly floor, advantage such as the regenerated liquid consumption is low, water production in periodic mode is big, effluent quality is good, flow is adjustable simultaneously.

Embodiment

Referring to accompanying drawing, the body of the two chambers of high flow rate described in the utility model ion-exchanger is divided into chamber 19 and following chamber 20, last chamber 19 filling weak type resins 2, following chamber 20 filling strong type resins 6, a band of being made by carbon steel line with rubber or acid-resistant stainless steel material is housed between upper and lower two

Room

19,20 twists the porous plate 4 of double speed water cap 3, in order to the liquid stream of linking up upper and lower chamber and make weak, strong two kinds of unlikely mixing of resin.Filling inertia duroplasts Archon 5 between porous plate 4 and the strong type resin 6.Top water inlet distribution device and regenerated liquid discharge equipment unite two into one, for mother manages arm water distribution pumping equipment 1; Resistance when moving for reducing equipment, the utility model does not adopt traditional quartzy bed course water-distributing device, but by be provided with the mode of the porous plate 22 of being with double speed water cap 21 in interchanger body bottom, bottom discharge device and regenerated liquid distribution device is united two into one.In addition, be provided with peep hole 9, the manhole door 17 that is used to overhaul that is used to observe, the mouth 10 that is used to adorn the mouth 8 of resin and unloads resin on the interchanger body, the member that links to each other with apparatus body has water intaking valve 11, outlet valve 14, backwash water intaking valve 12, backwash draining and regenerated liquid bleed valve 16, regenerated liquid feed liquor valve 13 and emptying tracheae 18.

In concrete the enforcement, the weak type that loads respectively in upper and

lower chamber
