Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
A kind of electric flocculation apparatus with swash plate electrode of the present invention, as shown in Figure 1, comprise housing, the top outer of housing is provided with air supporting slag scraper 5, the outside left and right sides of housing is separately installed with water inlet pipe 1 and rising pipe 8, water inlet pipe 1 is serpentine tube, the top of rising pipe 8 is provided with oil slick accumulator tank 6, oil slick accumulator tank 6 is metal sheet welding grooves, air supporting slag scraper 5 scrapes oil slick in this groove, the bottom opening of oil slick accumulator tank 6, tapping welds a pipeline, and oil slick is flow in collection container by pipeline.The side being installed into water pipe 1 in housing is provided with water distribution cloth tank 4.Enclosure interior is provided with swash plate electrode 2, and swash plate electrode 2 is arranged on the battery lead plate before and after described enclosure interior on two side for two or more, is parallel to each other and is the angle of 55 °-60 ° with horizontal direction between battery lead plate.Swash plate electrode 2 is fixed by electrode permanent seat a3 and electrode permanent seat b11, swash plate electrode 2 is 55 °-60 ° with the angle of horizontal direction, swash plate electrode 2 selects iron plate, stainless steel plate, graphite cake or aluminium sheet according to raw water quality, and swash plate electrode 2 adopts high frequency pulse power supply to power.Swash plate electrode 2 and electrode permanent seat a3, the concrete mounting means of electrode permanent seat b11 is: as Fig. 2, shown in Fig. 3, electrode permanent seat a3 and electrode permanent seat b11 welds respectively or is connected to before in housing with bolt, on rear two side, as shown in Figure 4, electrode permanent seat a3 is arranged with several slots a12 in parallel, slot a12 and horizontal direction are the angle of 55 °-60 °, as shown in Figure 5, on electrode permanent seat b11, the position corresponding with slot a12 is provided with slot b13 simultaneously, the vergence direction of slot b13 and angle of inclination and slot a12 match, be fastened by bolts in the slot b13 that each swash plate electrode 2 is inserted into slot a12 and correspondence.Swash plate electrode 2 is the one in iron plate, stainless steel plate, graphite cake or aluminium sheet, and every block swash plate electrode 2 has terminal stud, and compartment of terrain is connected with power positive cathode, that is the polarity of two often adjacent swash plate electrodes 2 is contrary.
Get back to Fig. 1, the top that enclosure interior is positioned at swash plate electrode 2 is provided with water leg 9 near case top place, the below that enclosure interior is positioned at swash plate electrode 2 is provided with perforated sludge discharge pipe 7, and perforated sludge discharge pipe 7 is arranged perpendicular to the front-rear side walls of housing, and the below of perforated sludge discharge pipe 7 is provided with V-type groove 10.Enclosure interior is divided into settling region and clear water zone, and the space of swash plate electrode 2 bottom is settling region, and the space on swash plate electrode 2 top is clear water zone.
Working process of the present invention is specific as follows: according to raw water quality condition and processing requirement, before Yuan Shui enters treatment facility, the medicaments such as filling coagulant aids, flocculation agent, emulsion splitter, make former water reach the inflow requirement for the treatment of facility, inject device of the present invention through water pump.
Former water passes through water circulating pump, through water inlet pipe 1, after entering water distribution cloth tank 4, during water outlet, current become the space that horizontal direction enters swash plate electrode 2 bottom, water distribution cloth tank 4 is grooves that the steel plate being vertically welded in housing inner top surface on the mouth of pipe opposite of water inlet pipe 1 surrounds, and the water (flow) direction that level can be made to enter this electric flocculation apparatus changes 90 degree, becomes downward direction, and then flowing to swash plate electrode 2 from housing bottom, break-in like this can effectively reduce impact when current directly enter.Current can be reduced to the sedimentary impact in settling region, the homogenizing of the medicament that simultaneously contributes to annotating in water through water distribution cloth tank 4 twice break-in.After settling region water is full, current can pass swash plate electrode 2, and after swash plate electrode 2 process, throw out is deposited to after settling region collects V-type groove 10, is discharged in mud recovery system through perforated sludge discharge pipe 7 by residual sea water pump; Suspended substance floats to surface, clear water zone, is recovered in oil slick accumulator tank 6 through air supporting slag scraper 5.The clear water zone that swash plate electricity level 2 top has about 600mm high, clear water flow to subsequent processing device after water leg 9.
Former water after swash plate electrode 2, electrolysis produce Ca 2+, Mg 2+plasma and OH -, CO 3 2-in conjunction with generation throw out, throw out and silt etc. sink to settling region.The electrolysis of swash plate electricity level 2 produces small H 2deng micro-bubble, the suspended substance that promoting flocculates produces and oil stain etc. float to the clear water zone water surface, collect in oil slick accumulator tank 6 through air supporting slag scraper 5.Swash plate electrode 2 combines the advantage of electricity flocculation and sloping plate deposition two kinds of techniques, the Fe that the electrolysis of electricity flocculation cathode plate produces 2+the OH of electrolysis in iron ion final sum water -ionic bond becomes to be insoluble in the Fe (OH) of water 3, increase precipitate density in water, can strengthen the sedimentation effect of swash plate electrode 2, the microbubble that electrolysis produces contributes to the flocculate suspended substance of generation and the ascent rate of greasy dirt, improves processing efficiency.
The present invention in conjunction with two kinds of equipment, substantially reduces treatment facility and takes up room simultaneously, transportation cost when saving equipment manufacturing cost and move.The micro-bubble that electrolytic process produces and the throw out that metal ion is formed can improve sloping plate deposition efficiency simultaneously.The pole plate group of battery lead plate will ensure when connecing electricity that negative electrode is in upside, is convenient to catholyte like this and produces H 2upwards overflow Deng micro-bubble, the Fe of anode electrolysis generation simultaneously 2+settling tank is flowed to along positive plate etc. flocculate precipitate.For ease of replacing and the maintenance of pole plate, pole plate group is made modular form, select unlike material, size, thickness and spacing according to raw water quality, pole plate group is made modular form, easy access and replacing.
