Detailed description of the invention
For ease of understanding, below in conjunction with the drawings and specific embodiments, the invention will be further described.
Shown in Fig. 1, this dehydration device includes: 1-rectifier power source, 2-anode cable, 3-cathode cable, 4 storage mud tanks, 5,6,7-check valve, 8-frame, 9-negative electrode conduction filter screen, 10-anode copper bar, 11-negative electrode copper bar, 12-mud cake, 13-membrane filter plate, 14-positive plate, 15-filter cloth, 16-Hydraulic Station, 17-material conveyor, 18-squeezes water pipe, 19-press pump, 20-air compressor machine, 21-mud screw pump, 22-mud passage；23-handle, 24-squeezes water channel, 25-barrier film cavity, and 26,26-drainage channel, 27-diaphragm plate, 28-solid slab, 29-cathodic electricity nose.
Fig. 1, electro-osmosis diaphragm filter press structural representation, anode cable 2 and 3 connects on rectifier power source 1 respectively, anode cable 2,3 is connected with anode copper bar 10, negative electrode copper bar 11 respectively simultaneously, mud is pumped, through storage mud tank 4, the sludge pipe sending into pressure filter through check valve 5 by mud screw pump 21, and mud passage 22 and sludge pipe communicate.Squeeze water is squeezed pump 19 by squeezing water pipe 18, pumps into membrane filter plate 13 through squeezing water channel 24.
The each handle of mid-positive plate about 14 of Fig. 2 and 3, is supported in frame 8, and positive plate 14 is connected on anode copper bar 10, is connected on rectifier power source 1 by anode copper bar 10.Special cathode conduction filter screen 9, is arranged on both sides shown in membrane filter plate 13 Fig. 6, draws cathodic electricity nose, forms combination filter plate, as shown in Figure 6, is connected on negative electrode copper bar 11 by cable, is connected on rectifier power source 1 by negative electrode copper bar.By positive plate 14 between double; two membrane filter plates, being divided into 2 homogeneous spaces, when being full of mud, filter cake 12 is by cathode filter screen 9 filter cloth 15, and positive plate 14 clips, and is similar to and regards resistance as, forms uniform electric field.Mud is charged colloidal particle, and resistance sizes is determined by mud self-conductance rate.
Fig. 4 and Fig. 5 is structural representation and the sectional view of the membrane filter plate of the present invention, is made up of the barrier film cavity 25 of an opposing seal two diaphragm plates 27, and solid slab 28 is placed in the centre of barrier film cavity 25, and barrier film cavity 25 is divided into two parts；Barrier film cavity 25 with squeezing water channel 24 be connected, the centre of membrane filter plate is provided with mud passage 22, membrane filter plate be all around provided with drainage channel 26.
Fig. 6 is membrane filter plate assembling diagram, and wherein the size fit of filter cloth 15, positive plate 14 and diaphragm plate 27, is in particular 630 × 630；The depressed area size fit of negative electrode conduction filter screen 9 size and diaphragm plate, is specially 530 × 530；The mud cake ultimately formed is sized to 530 × 530, and thickness is about 35.
Wherein membrane filter plate is prepared from by RPP.
Rectifier power source 1 is by pre-set programs, and according to pressure transmitter feedback signal, timing sends time variant voltage electric current.Multistage loadings conducts electricity on filter screen 9, positive plate 14 to negative electrode.Resting on mud cake generation electro-osmotic effects between anode and negative electrode filter cloth 15, in mud cake, Bound moisture is separated.Plus high-pressure press pump 19 is full of barrier film and carries out mechanical expression, and mud cake die cavity reduces further and reaches more than 50%, reaches dehydration purpose.
During work, Hydraulic Station 16 is to oil cylinder pumps hydraulic oil, and oil cylinder pushing compresses a series of membrane filter plates 13.In storage mud tank 4,80% water content sludge is pumped by mud screw pump 21, is entered by check valve 5 and combines in filter plate 13 in frame 8, shown in mud cake 12 Fig. 2 of formation, is between negative electrode and anode, it is possible to being similar to and regard resistance as, resistance sizes is determined by mud electrical conductivity.Owing to mud is charged colloidal particle, under electric field action, mud granule is assembled to anode, and moisture is assembled to negative electrode.Continue charging in advance, until pressure reaches 1.2Mpa, close mud screw pump 21.Then rectifier power source 1, startup press pump 19, electro-osmosis simultaneously and squeezing operation are started.Squeeze water is squeezed pump 19 by squeezing water pipe 18, pump into membrane filter plate 13, barrier film tympanum, mud cake 12 die cavity is forced to diminish further, under autoclave diaphragm machinery continues to squeeze, in mud, more than 60% water flows out from negative electrode conductive mesh 9 through filter cloth 15, discharges through membrane filter plate 13 water channel, reaches dehydration purpose.
In the electro-osmosis later stage, autoclave diaphragm machinery stops squeezing, and air compressor machine 20 starts, and pressure-air quickly enters feed pipe, and blowout major part enters mud pipeline mud, is pressed onto on anode plate, carries out secondary electroosmotic dewatering.When machine no longer water outlet, the internal squeeze water emptying of barrier film, pressure-air quickly enters binding face between filter cloth 15 and mud cake 12, blows mud cake, is forcibly separating mud cake and filter cloth.After plate left by machine, mud cake departs from filter cloth 15, anode plate 14 by gravity automatically, falls on material conveyor 17, and mud cake is transported outward.
This sludge electroosmotic saturating dehydration apparatus structure is simple, reliable, it is possible to realizes moisture percentage in sewage sludge and is reduced to less than 50%, improves 2-3 times of dewatering efficiency than diaphragm filter press.
A kind of change as the present invention, the cathode and anode conduction filter screen lining of the membrane filter pressing unit of the present invention at the described filter cloth back side and is connected with cathode and anode pole copper bar respectively, and membrane filter pressing unit is made up of two above-mentioned membrane filter plates arranged side by side and constitutes the storage mud cavity with electroosmosis of an opposing seal.
Although what above detailed description of the invention was told about is that squeeze water is squeezed pump 19 by squeezing water pipe 18, pump into membrane filter plate 13 through squeezing water channel 24；Simultaneously the present invention comprise that the barrier film cavity etc. that special cathode conduction formed between the membrane filter plate of filter screen 9, membrane filter plate constitutes membrane filter plate unit, the membrane filter plate filter-pressing device that is made up of several membrane filter plate unit completely can on other pressure filter of the pressure strip of prior art and cylinder body external force squeezing dehydration device (such as Chinese patent CN202860204U, CN102527114A).
The above; being only the present invention preferably detailed description of the invention, but scope is not limited thereto, any those skilled in the art of the present technique of being familiar with are in the technical scope that the invention discloses; change can be readily occurred in or replace, all should be encompassed within scope.Therefore, scope should be as the criterion with claims protection domain.
