Description
The invention belongs to the refining plant of natural water and sewage, more precisely say, is a kind of device with sewage purification.
Known a kind of electrolyser for sewage purification (SU, A, 1112003) be make of an electro-conductive material and garden tubular tank that join with power cathode, the particulate state labor and materials that electro-conductive material is made are housed in this tank, but labor and materials are and the tank insulating to have settled the current input electrode that joins with positive source in the particle labor and materials.Current input electrode is foraminous, its medullary ray and the co-axial metal sleeve of tubular tank on hollow, the wall.After sewage entered tank, the water-soluble anode labor and materials (particulate material) of flowing through entered sleeve pipe by the perforate on the wall again, flow out from electrolyzer along sleeve pipe at last.
In this electrolyzer, the water that purified is embezzled and is being closed the impurity that electrolytic process produces, and when the labor and materials intergranular space of direct current through remaining static, these impurity alluvials form some sloughs in the space.So the work of this electrolyzer need the electric energy of consumption big, and water purification efficient is low.
Also has a kind of electrolyser for sewage purification (SU.A.1104113), it has a tubular tank that join with power cathode, that made by electro-conductive material, settle the tubular box of perforate on the wall in the tank, fill the particulate state labor and materials of conduction in the box, it and positive source (we claim that it is an electrode box) the And that joins is equipped with and can makes electrode box center on the device that symmetry axis rotates, the electrode box outside surface has an insulation interlayer, electrolyzer also has two pipe connectings, a pipe is used for sewage is sent into electrolyzer, and another pipe is used for treated water is sent.Tank and electrode box are coaxial upright placements.The sewage that need purify is sent into the bottom of container, through interelectrode space, just passes through the annular gap between tank and the box, flows out from the top of tank then.The intergranular space of labor and materials is blocked in the box, specially makes box periodically rotate ， And and makes the vertical translational motion that comes and goes.
In this electrolyzer, labor and materials particulate activity (effectively) district only is near those zones the electrode box cylindrical surface with holes, and other labor and materials are to be connected on the positive source as anode in the electrode box, and not aseptic.Pending water, the space mobile between electrolytic tank electrode is carrying dissolved metal ion simultaneously.Liquid and labor and materials remain static in anode cassette down.
The electrode box that labor and materials are housed is made periodical rotation, thereby produces a centrifugal force, if the labor and materials transfixion does not so just have this centrifugal force, is blocked up by drift so just can not prevent the hole in the labor and materials.The eccentric wheel of equipping on the electrode box turning axle makes electrode box carry out vertically coming and going translational motion, and it only works to increase waste concentration.In addition, generate insoluble compound in order to prevent electrolytic process in the hole of labor and materials, in the central zone of box, inject weakly acid soln by axle with holes, it will reduce the active reaction (pH value) of water.But acid solution and labor and materials particle only play a little reactions at the initial stage of injecting acid, and after, the active reaction of processed water (pH value) no longer changes.Therefore, above-mentioned measure can not be avoided the labor and materials alluvial.
In addition, in order to overcome the alluvial phenomenon, and guarantee the certain flow for the treatment of water, must make enough big in pole clearance, thereby must improve the operating voltage of electrolyzer.
The task of this patent, be to make a kind of like this electrolyzer of purifying waste water, the structure formation of its tank and electrode box and relative position, can guarantee when purifying waste water, stirring particles labor and materials effectively, thereby improve the utilising efficiency of labor and materials, And cuts down the consumption of energy when improving electric tank working efficient.
This task is to solve like this, electrolyzer comprises a garden tubular tank that join with power cathode, that made by electro-conductive material, an electrode box with holes that is contained in the garden tubular in the tank, the particle And that makes of electro-conductive material is housed in the box to join by input electrode and positive source, the device that can make the electrode box around its symmetry axis rotation, an interlayer of making of insulating material that wraps in box outside, also comprise sewage sent into the water inlet pipe of electrolyzer and makes sewage disposal after effusive rising pipe.According to this patent, electrode box can be free movable in the tubular tank, but vertical symmetry axis of vertical symmetry axis of box and tank is parallel, and the vertical symmetry axis of tank and the angle of horizontal plane are less than 90 °.
Change easily in order to make electrode, the position that electrode box is laid in tank is such, the outside surface of its garden column can optionally abut on the internal surface of tank, the parts that the electrode box is rotated are rotary actuators, its moment of rotation, at least act on the outside of tubular tank by a pair of rotor, this a pair of rotor is fixed on the output shaft of transmission rig tightly, and And reaches by the interaction of the tubular outer side of the side of rotor and tank and rotatablely moves.
When water electrolytic gas that the needs utilization produces in the purifying waste process (for example being used for flotation), tank adopts ring-type, the axle of ring is parallel with ground level, the inboard of ring-type tank abuts on the tubular outside of electrode box, and the turning unit of electrode box is a rotating actuator, and its moment of rotation acts directly on the turning axle of electrode box.
The advantage of this electrolyzer is, the position relation of above-mentioned tank and tubular electrode box has constituted minimum pole distance, in this case, electrode box simultaneously rotates, one side is rolled along the internal surface of tubular tank, this has just stoped the deposition ， And that produces on the tank internal surface as negative electrode to make to carry out exchange of substance to greatest extent between labor and materials particle and the processed water.The labor and materials particle rolls continuously and has played the effect of self cleaning in electrode box, and this just makes the labor and materials surface have very high chemically reactive.
Because electrode box can move freely in the tank of refining plant, so, in electrolyzer gaps between electrodes change be lower-most point O from device to vertex L, this pole distance is by the difference decision of electrode box diameter and tank diameter.So the current density on this device electrode surface is that uneven ， And changes with pulse mode in the course of the work.The pulsating nature of current density makes the electromotive force on the electrode be subjected to the influence of passivation phenomenon less.
Electrolyzer with this structure design characteristic, expending of its electric energy will be more much lower than the structure of existing electrolyser for sewage purification.
The following describes some specific embodiments of this patent and the schema that suggestion is adopted.But they can not represent whole embodiments of this patent.
These figure are:
Fig. 1 shows the longitudinal sectional drawing according to the electrolyser for sewage purification general assembly drawing of this patent design;
Fig. 2 is the II-II sectional view of electrolyzer shown in Figure 1;
Fig. 3 is the electrolyser for sewage purification general assembly longitudinal sectional drawing according to this patent design;
Fig. 4 is the sectional view of electrolyzer shown in Figure 3 along IV-IV.
The electrolyzer that is shown in Fig. 1 and Fig. 2 comprises a garden tubular tank (1), the negative pole that it makes ， And and power supply by electro-conductive material join (not shown on the figure).Tank (1) is the metal garden tube of a hollow, and its two ends correspondingly are connected to the water inlet pipe (3) and the rising pipe (4) of disposing of sewage by end cap (2) sealing on two end caps.Settle an electrode box (5) in tank (1), fill the particle labor and materials of being done by electro-conductive material (6) (for example, pig scrap, iron filings, graphite bits) in the box, electrode box has conducting plates (7), and it is the plate metal blade that joins with positive source.Electrode box (5) is a hollow cylinder (8) that is drilled with a lot of holes (9), and the insulation interlayer of being done by dielectric material (10) is equipped with in the electrode box outside.There is end cap (11) at the two ends of tube (8).Electrode box (5) can be free movable in the tank of electrolyzer, and its vertical symmetry axis is parallel to vertical symmetry axis of tank (1).The installation of the tank of electrolyzer (1) should become one with horizontal plane less than 90 ° angle.Parallel with horizontal plane in this example.
Electrode box (5) abuts on the inner core face of tank (1) with its urceolus face, and tank (1) itself is with its outside surface and rotation roller (12), and the side of (12 ') interacts, and the moment of rotation of roller acts on the urceolus face of tank (1).One pair roller (12) is securely fixed on the output shaft (13) of transmission mechanism (14), and And passes to tank (1) with the moment of transmission mechanism (14).Another pair roller (12) plays supporting role, prevents that electrolyzer from toppling over.
Different with electrolyzer illustrated in figures 1 and 2 in the electrolyzer embodiment on being shown in figure (3) and scheming (4), tank (15) is the garden cyclic, and the axle of garden ring is parallel with horizontal plane.Tank (15) abuts on the urceolus face of electrode box (5) with its inner core face, and the turning unit of electrode box (5) is to rotate driver (16), and its moment of rotation is applied directly on the turning axle of electrode box (5).In the embodiment of this electrolyzer, the water inlet pipe of processed sewage (3) inserts inner by an end cap (11) of tubular electrode box (5).Water after electrolyzer is handled goes out by the orifice flow on many holes (9) on the garden shape tube (8) in the electrode box and the insulation interlayer (10).
In the embodiment of two kinds of electrolyzers, the maximum value L of pole distance is decided by tank (1) (Fig. 2), the difference of the diameter of the diameter of (15) (Fig. 4) and electrode box (5) (diameter of garden tube (8)) between the two.In the tank (1) of electrolyzer or (15), can place several electrode boxs (5), the processing requirement when the function needs that how much depend on equipment of electrode box number and equipment use.
Under the situation of a plurality of electrode boxs, the structure of electrode box (5) is identical, can exchange De ， And and in tank (1) or (15), all settles in co-axial mode each other.
The electrolyzer that is shown on Fig. 3, Fig. 4 can be equipped suspension bracket (not shown on the figure), and this suspension bracket is fixed on the turning axle of electrode box (5).This electrolyzer can supply water separately and draining (for example, the discharging of electroplating effluent in the Electroplating Production) to each container.
More than be some optimum implementation that we describe, that be used for the explanation this patent, the expert for being engaged in this field work understands certainly, in not exceeding this patent requirement scope of project, can also make many changes to above-mentioned embodiment.
Be shown in the design of the electrolytic cell on Fig. 1, Fig. 2 by following mode work. Sewage (water such as, electroplating workshop cleans contains zinc, nickel, chromium plasma in this water) enters the tank (1) of electrolytic cell through water inlet pipe (3). By the motor of driver (14), the tank of electrolytic cell (1) the ， And that rotates will rotatablely move and pass to electrode box (5), and like this, electrode box just rolls along the inner surface of tank (1). When tank (1) and electrode box conductive plate (7) when adding voltage, the water generates electrolysis of the electrolytic cell of flowing through. At the tank as electric tank cathode hydrogen ion discharge taking place, produces hydroxide ion OH- On anode, just on the metallic particles labor and materials (6) (such as iron filings), ferrous ion is separated out in the iron filings dissolving. Because the concentration diffusion in electric field, ferrous ion moves Tu ， And at gap location from electrode box (5) to electrode gap, ferrous ion and hydroxide ion OH-Interact, generate the iron hydroxide of divalence. The diatomic hydrogen iron oxide enters in the pending current, make hexavalent chrome reduction become trivalent chromium, and itself become the iron hydroxide of trivalent, after this, the iron hydroxide of trivalent just becomes flocculating agent and the sorbent (, for zinc ion and nickel ion) that can remove heavy metal ion from water here. Send into efficient cyclone (for example, filter, thin layer sedimentation basin) by the electrolytic cell treated water, the pollution impurity that And will condense there filters away from water.
Whole processing procedures of water are all carried out in electrolytic cell rotates continuously. Labor and materials particle (6) stirs in electrode box (5), thereby plays a part simultaneously abrasive material ， And and clean passivation layer at self Surface Creation, and this also causes the chemical attack that metallic is very fast.
In the electrolytic cell, interelectrode distance is by the variation of maximum L to O, makes the current density on metallic particles (6) surface of dissolving inhomogeneous. So when electrode box (5) rolled along cathode inner surface, metallic particles (6) was to dissolve under the current density effect of pulsation, this has just been avoided the passivation of metallic particles (6). In addition, the inner surface of tank (1), negative electrode just is because electrode box (5) is to roll in the negative electrode tank, so can constantly dispose issuable deposit on the cathode surface.
Be shown in the operation class of electrolytic cell on Fig. 3, Fig. 4 and above-mentioned electrolytic cell seemingly, their difference only is, when tank (15) when being porous or netted, the gas that produces at negative electrode during electrolysis, can be used for floatation process, because it can not only condense and collect the pollution impurity in the water, and can make impurity become foam-like material, on the floating watermeter face.
Above we have analyzed the scheme of the electrolytic cell of a kind of employing metal labor and materials (6). In the situation when filling with graphite or coke labor and materials (6) in electrode case (5), can make the impurity of polluted water produce anode oxidation process, this is similar to the device with porous anode.
Being equipped with in the situation of mixing labor and materials (for example, graphite and iron), surperficial hardening process may take place, or the deposition (such as copper ion deposition) of the metal in the sewage on negative electrode. If electrolytic cell (Fig. 3) is immersed in the liquid that needs to process, not whole immersions, but part immerses, such as only has 1/3 of tank (15) diameter, so, even in the situation in disconnected power down source, this equipment also can be used for removing succession in the water with the formation of magnetic oxide, and these magnetic oxides are because airborne oxygen makes due to the iron ion oxidation.
The electrolytic cell of purifying waste water can be used for chemistry, electrochemistry, machine-building, the energy, food and other industrial circle. Be specially adapted to those and now remove the sewage purification work of polluting impurity by the soluble metal ion that in processed liquid, adds the electrode labor and materials. This electrolytic cell is best suited for the sewage purification work that produces flocculating agent by electrochemical process, as electroplating the sewage purification work of producing.
