Abstract
The utility model provides an efficient ion exchanger. The efficient ion exchanger comprises a tank body, a vertical partition board, an ion exchange resin, a filter plate, water caps, a water inlet pipe and a water outlet pipe, wherein the tank body is divided into two parts by the vertical partition board, the filter plate is mounted in the hollow cavity of the tank body, the water caps are mounted on the filter plate, the hollow cavity of the tank body is filled with the ion exchange resin and the ion exchange resin is positioned below the filter plate, and the water inlet pipe and the water outlet pipe are arranged on the two sides of the vertical partition board and at the upper part of the tank body; when the ion exchanger is in normal operation, raw water flows to the upper layer space of the ion exchange resin through the water caps and the filter plate from the water inlet pipe, the water flowing manner in the ion exchange resin is that the water is pressed downwards firstly, and then returned back for rising, and the raw water flows out of the tank body through the water caps, the filter plate and the water outlet pipe after flowing through the ion exchange resin. According to the efficient ion exchanger, the problems that the water inlet and the water outlet of the exchanger are easy to block and the resin is easy to harden are solved; meanwhile, the efficient ion exchanger has the advantages that the water preparing amount can be increased greatly, the design is reasonable, and the ion exchanger is convenient and practical.
Description
Technical field
The utility model is a kind of high-efficiency ion exchanger, and particularly a kind of high-efficiency ion exchanger for heavy metal wastewater thereby suite of equipment belongs to the renovation technique of high-efficiency ion exchanger.
Background technology
Process for treating heavy-metal waste water is a lot, mainly contains chemical precipitation method, ion exchange method, iron replacement method and ferrite process etc.Wherein chemical precipitation method use is the most general, and the metal being worth containing higher reclamation, as the wastewater treatment of nickel, chromium etc., the ion exchange methods that adopt more.
Apply the form that comparatively general ion-exchanger generally adopts co-current regeneration formula fixed bed, counter-current regeneration formula fixed bed and backhaul ion-exchanger.In co-current regeneration formula fixed bed, the flow direction of regenerator is identical with flowing to of processed water, and when regeneration, from front end to rear end, resin saturation ratio and regenerated liquid concentration all reduce gradually, cause rear end resin regeneration weak effect, and system regeneration liquid consumption is large.Its recovery stream of counter-current regeneration formula fixed bed, to contrary with the operation flow direction, has favorable regeneration effect, the advantage that regenerated liquid consumption is few.But disorderly layer phenomenon of resin easily occurs counter-current regeneration formula fixed bed, for avoiding it to occur, need to adopt pneumatic jack, water top or reduce the methods such as operation flow velocity, thereby occurring equipment and complicated operation, the problem such as water loss is large, plant factor is low.
Return stroke type softener is to have set up vertical partition plate in the middle of cylindrical body, by rounded section in two.Fluid enters and flows downward from a upper lateral part, turns to opposite side upwards to flow again from the lower partition, flows out from the top of this side, is so backhaul form by resin layer, and its regeneration is counter-current regeneration.Push down resin because current enter top, thereby can not produce disorderly layer phenomenon.Return stroke type softener has been inherited all advantage of counter-current regeneration formula fixed bed, has overcome again the easily shortcoming of random layer of resin, easy and simple to handle, needn't strictly control regeneration velocity, and body height is little, simple in structure.
The inlet tube and outlet tube of traditional return stroke type softener and small reverse washing water inlet pipe all use filter screen wrapping, and than the form of filter plate+water cap of fixed bed, its flow area greatly reduces.In the time that water inlet contains more suspended substance and silt, impurity, easily there is the problem of stopping up.Tiny silt and mud easily enters in interchanger by filter screen simultaneously, and forms piece with resin, because water flow mode is for first pressing down, then upper punch, backwash intensity is difficult for promoting, and while causing backwash, mud cannot depart from from resin surface.In the course of time, resin layer resistance is increased, discharge reduction processed because mud is wrapped in resin, makes resin regeneration incomplete simultaneously, has not only wasted a large amount of regenerators, and has shortened water production in periodic mode.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and high-efficiency ion exchanger that a kind of easy blockage problem of intake-outlet that has solved interchanger is provided.The utility model can increase the water yield processed greatly, reasonable in design, convenient and practical.
The technical solution of the utility model is: high-efficiency ion exchanger of the present utility model, include tank body, vertical partition plate, ion exchange resin, filter plate, water cap, water inlet pipe, rising pipe, tank body is separated into two portions by vertical partition plate, filter plate is installed in the hollow cavity of tank body, water cap is installed on filter plate, ion exchange resin is installed in the hollow cavity of tank body, and be positioned at the below of filter plate, the top of tank body is respectively equipped with water inlet pipe and rising pipe in the both sides of vertical partition plate, when normal operation former water from water inlet pipe through water cap, filter plate enters the upper sheaf space of ion exchange resin, water inlet is first to press down the rising of turning back again in the mistake stream mode of ion exchange resin, former water flows through after ion exchange resin again through water cap, filter plate and rising pipe flow out tank body.
Above-mentioned water inlet pipe in the time of back flushing as back flushing rising pipe, rising pipe in when recoil as back flushing water inlet pipe, back flushing feed water flow to former water feed water flow to contrary, flow into tank body from rising pipe, flow out from water inlet pipe.
Compared with prior art, tool has the following advantages the utility model:
1) the utility model has improved traditional return stroke type softener, intake-outlet has adopted filter plate to install the form of water cap additional, with respect to the form of traditional filter screen wrapping water inlet pipe and water outlet pipe, flow area increases mutually greatly, and sheaf space is larger on filter plate, impurity and silt are had to certain carrying capacity, and when back flushing, impurity and silt are easily discharged, thereby the intake-outlet that has solved traditional return stroke type softener holds susceptible to plugging problem;
2) back flushing water inlet pipe is set up in interchanger of the present utility model bottom, with respect to first pressing down of traditional return stroke type softener, the water flow mode of upper punch again, backwash intensity lift-rising greatly, thereby can effectively clean suspended substance and the mud of resin surface deposition and cut-off filter, thereby solve that influent turbidity is high, silt and impurity is when many, the problem that resin easily hardens.
The utility model is that a kind of design is ingenious, excellent property, convenient and practical high-efficiency ion exchanger.
