Embodiment
In Fig. 1, the utility model is a kind of oily-water seperating equipment, it comprises strainer 1, one-level water-and-oil separator 2, spiral pump 3, oil content concentration alarm record instrument 5, magnetic valve, strainer 1 is connected with the inside of one-level water-and-oil separator 2, one-level water-and-oil separator 2 comprises the gathering room at top and the coalescer of bottom, the top of one-level water-and-oil separator 2 is provided with the oil level detection device, be connected with magnetic valve on the oil level detection device, bottom at one-level water-and-oil separator 2 communicates with the suction port of spiral pump 3, be provided with T-valve 7 in spiral pump 3 exits, first valve port of T-valve 7 is connected with spiral pump 3 outlets, spiral pump 3 outlets are passed through second valve port and are connected at oil content concentration alarm record instrument 5, it also comprises secondary filter 4, be provided with the high precision fiber filter core in the secondary filter 4, fabric filter element is connected with secondary filter 4 by screw thread, in secondary filter 4, also be provided with electric contact pressure, the outlet of spiral pump 3 is connected by the import of the 3rd valve port with secondary filter 4, be connected with secondary oil in water emulsion separator 6 on the secondary filter 4, the top that secondary oil in water emulsion separator 6 is provided with is provided with the micro-filtration element, be provided with some distribution openings and oil in water emulsion separative element successively in the bottom, the lower inlet of secondary oil in water emulsion separator 6 and the outlet of secondary filter 4 are joined, and the outlet on the top of oil in water emulsion separator is connected with oil content concentration alarm record instrument 5.Primary separator is made up of top gathering room and bottom coalescer.Bottom connecting screw rod pump inlet.
According to Fig. 2, work of the present utility model is as follows: in the drainage procedure of spiral pump 3 after the relief outlet place of one-level water-and-oil separator 2 suction process, make and produce vacuum in the one-level water-and-oil separator 2, limber water enters one-level water-and-oil separator 2 internal divergence spouts through coarse filter 1 and top suction/draining valve, carry out gravity separation, larger oil droplet is floating to the top gathering room, the sewage that contains the small-particle oil droplet enters special coalescer downwards, carry out coarse separation in inside, form than larger oil droplet and continue come-up to the top gathering room.Sewage after the separation is discharged by spiral pump 3 through the separator bottom, qualified discharge water row outboard.When discharge water was not up to standard, oil content concentration alarm record instrument 5 sent signal, and 7 actions of crossover tee valve make first grade discharging water enter secondary oil in water emulsion separator and proceed the micro-filtration separating treatment.The oily water that contains superfine small oil droplet and small suspended solid is after secondary filter filters, enter secondary oil in water emulsion separator 6 bottoms, by importing after several distribution openings in the oil in water emulsion separative element, after sump oil is stopped by the element micropore, blowdown variable valve by secondary oil in water emulsion separator 6 tops with partial reflux sewage reboard at the bottom of, most of sewage is accumulated clean water up to standard by millipore filtration and discharges outboard.When secondary oil in water emulsion separator handling property lost efficacy, secondary discharges when defective, and oil content concentration alarm record instrument 5 sends signal once more, and the reboard magnetic valve is opened, at the bottom of the treating water reboard.Sump oil after the separation gathers to a certain degree at the top of one-level water-and-oil separator 2, and the oil level detection device sends signal, enters separator by the solenoid control clear water and carries out back flushing, and the sump oil that is collected at the top is arranged automatically to wiper tank.
