Description

A kind of electric deionizer
Technical field
The utility model relates to a kind of device, especially relates to a kind of electric deionizer that is used for water treatment.
Background technology
Electric deionizer claims filling bed electrodialyzer again, is a kind of device for preparing high purity water.It is in conjunction with the advantage of electrodialytic technique and ion exchange technique, ion exchange and yin, yang ion-exchange membrane by ion exchange resin select to see through effect to the yin, yang ionic, under galvanic effect, realize the ionic directional migration, thereby finish the deep desalting of water.Simultaneously, water molecules is decomposed into hydrogen ion and hydroxide ion under electric field action, and Zeo-karb and anionite-exchange resin are carried out cyclic regeneration, makes ion exchange resin keep reproduced state, can continuously prepare high purity water.Electric deionizer has overcome mixed bed in use needs the interruption shutdown to carry out this shortcoming of chemical regeneration because of ion exchange resin is saturated gradually; do not need acid, alkali regeneration, non-wastewater discharge, running cost is low; convenient operation and management is the equipment of the preparation high purity water of tool development prospect.
The electrodeionization assembly of the electric deionizer that uses mainly is made up of gripping unit, electrode device and membrane stack at present.To forming, each film is to forming filling ion-exchange resin in the diluted gasket by anode membrane, dense water dividing plate, cavity block, diluted gasket by several films for membrane stack.Form utmost point hydroecium, freshwater room, dense hydroecium in the device, can continuously prepare high purity water.
Utility model patent ZL99241918.2 discloses a kind of electric deionizer, mainly comprise membrane stack, electrode device and gripping unit three parts, by designing a kind of light chamber dividing plate, select potting resin density, improve the filling situation, and at dividing plate entrance and exit place, light chamber, the runner of a secret tunnel formula of design, current are evenly distributed, prevent that the film at dividing plate entrance and exit place, light chamber from subsiding, resin leakage and obstruction.This diluted gasket is made up of diaphragm body and cover plate, leaves the gap of 0.1-0.3mm between cover plate and the diaphragm body, is used for the turnover runner of fresh water, prevents the loss of resin.The shortcoming of this structure is that cover plate is thinner, and the point of suppon spacing is bigger, be easy to generate the distortion and cause film to subside, cause the internal leakage of resin and water easily, the major surfaces of diluted gasket is the leakage that optical plane also easily causes water.The length in the gap of cover plate and diaphragm body must be less than the inside casing of diluted gasket simultaneously, and total flow area is less, and resistance to flow is bigger, water distribution is even inadequately, some ribs are arranged in the diluted gasket inside casing, taken the space of ion exchange resin, influence the water treatment effect.
Summary of the invention
The utility model provides a kind of electric deionizer, and the diluted gasket of this device is not yielding, and the flow resistance is little, be evenly distributed the water treatment efficiency height.
The technical solution of the utility model is: a kind of electric deionizer, comprise water circuit system, gripping unit, electrode device, membrane stack, membrane stack by some films to forming, each film is to being made up of anode membrane, dense water dividing plate, cavity block, diluted gasket, diluted gasket is made up of body and inside casing, filling ion-exchange resin in the inside casing, original water inlet, dense water inlet, water outlet, dense water out and utmost point water out are arranged on the body, original water inlet and water outlet communicate with being located at intrinsic hollow flow passage respectively, and hollow flow passage and inside casing junction are provided with water distribution board.
Have several trapezoidal flumes on the described water distribution board, the osculum gap width of trapezoidal flume is less than the diameter of ion exchange resin.
The both sides of described water distribution board and described body are fixed.
Described diluted gasket body is provided with sealing groove.
Described gripping unit is made up of end plate, side plate, by bolt end plate and side plate is fixed, and the dividing plate in the membrane stack is clamped.
The water inlet water route of water circuit system is entered by the end plate below, the parallel membrane stack that runs through, and draw from the top of same end plate in the water outlet water route.
Diluted gasket water distribution board in this device has played two effects, and the one, prevent the loss of resin, another is to carry out water distribution.Water distribution board is fixed in the diaphragm body, has improved the planeness and the rigidity of dividing plate, flow path wall is had booster action, prevent that flow path wall from causing subsiding of film because of distortion, thereby prevented interior leakage effectively.Water distribution slot length direction on the water distribution board is vertical with the principal plane of dividing plate simultaneously, has increased the area of runner, has reduced the resistance of water.The principal plane of diluted gasket is provided with sealing groove, to increase the sealing effectiveness of diluted gasket.
Gripping unit of the present utility model clamps end plate and side plate by bolt, clamps the dividing plate in the membrane stack, prevents leaking outside and the leakage of water of resin in the dividing plate.Side plate plays the transition ligation between the bolts at two ends, and plays the effect of the frame of strengthening diluted gasket and dense water dividing plate, prevents to be subjected to the effect of working pressure in the dividing plate and produces distortion, makes ion-exchange membrane not fragile.
