Abstract
The utility model relates to a U-shaped combined ion-exchanger, comprising a U-shaped ion exchange column, an exterior pipeline system and a regeneration liquid system which are integrated into one body. The inner surface end of the U-shaped ion exchange column is respectively provided with a water inlet liquid draining apparatus, a liquid inlet water draining apparatus and a local backwashing water inlet apparatus. Exchange resins in the U-shaped ion exchange column are respectively fixed by three partition boards, and the utmost upper part of the exchange resins is fixed by a resin pressing layer. The novel combined ion-exchanger adopts a counter-current regeneration mode, but the water and liquid inlets and outlets are all arranged on the upper part, so that the advantages of a co-current regeneration and counter-current regeneration exchanger and a floating bed type exchanger are centralized.
Description
The utility model belongs to water treatment facilities.
For the former water that contains Ca, Mg is softened, mainly adopt the sodium ion exchange process, so ion-exchanger is the indispensable water treatment facilities of boiler, cooling device.Existing ion-exchanger is generally and can bears the 4-6 kilograms per centimeter
2The cylinder of steel of pressure, inner filling ion exchange resin.Difference according to its traffic direction, be divided into co-current regeneration ion-exchanger and countercurrent regenerating ion exchanger, the former is meant former water and regenerated liquid respectively from top to bottom with the same direction ion-exchanger of flowing through, and the latter is meant that former water and regenerated liquid flow to opposite ion-exchanger.The counter-current regeneration interchanger can be saved regenerative agent than the co-current regeneration interchanger, improves effluent characteristics, but equipment is complicated, and operating procedure is many, and former water is had relatively high expectations.And occur disorderly layer of exchanger easily, and need the roof pressure measure.Existing a kind of floating ion exchanger also adopts the counter mode, but the water (flow) direction of its operation and regeneration is opposite with counter-current regeneration just, when promptly moving, current are from bottom to top, simultaneously resin bed are held up, during regeneration, the regenerated liquid flow direction is from top to bottom, this kind interchanger has more made full use of the interchanger volume than co-current regeneration and counter-current regeneration interchanger, and resistance to water-flow is little, does not have backwash process, save backwash water, also can not cause disorderly layer of exchanger.But influent turbidity is required height, and will set up external back-washing equipment.More than the ion exchange column of various ion-exchangers separate with the regenerated liquid system.
At the defective of existing ion-exchanger, the utility model is a strong point of wanting comprehensive various ion-exchangers, designs a kind of novel combination type ion-exchanger.
This U type combined ionic interchanger is made up of U type ion column-programming, external pipeline system and regenerated liquid system, and the three combines as a whole, U type ion column-programming both ends open place is provided with into water, row's regenerated liquid device respectively and advances regenerated liquid, drainage arrangement, and a side of water, row's regenerated liquid device is provided with local backwash water feed apparatus having into.More than the two ends exchange resin surface packed resin layer is arranged in the U type ion exchange column, the exchanger resin in the middle of the U type ion-exchange column bottom separates with dividing plate.External pipeline system by water inlet pipe, outlet pipe, advance the regenerated liquid pipe, go out the regenerated liquid pipe, local backwash water inlet pipe, local backwash outlet pipe, just wash out water pipe and form; The regenerated liquid system by dissolved salt post, saline solution Filter column, brine tank, regenerative pump and between connecting line form.
This U type combined ionic interchanger is owing to adopt U type ion exchange column, and employing counter-current regeneration mode in service has so not only been concentrated the advantage of co-current regeneration, counter-current regeneration and floating bed formula ion-exchanger, and overcome the shortcoming of pot type ion-exchanger in the past.Specifically, following characteristics are arranged: (1) former water and regenerated liquid are imported and exported all on top, therefore do not need quartz sand thickness, have avoided the silico-calcium pollution; (2) owing to combine fixed bed and floating bed, the random problem of waste regenerative agent when layer and co-current regeneration of exchanger when having solved counter-current regeneration; (3) the water inlet flow velocity there is not strict boundary; (4) hydraulics is good, and resin does not have the dead angle in the post; (5) because water inlet, feed liquor is all on top, the suspension that water body carries can not amass in the resin bed bottom, therefore only needs clean surface, does not need big reverse washing; (6) equipment is simple, easy to operate, easily grasps.Because U type ion exchange column and regenerated liquid system combine as a whole, install and operate more convenient simultaneously.
