Description
Technical field
The present invention relates to a kind of oily-water seperating equipment of handling oily(waste)water; especially when sewage emulsification is serious; can carry out second-stage treatment,, make discharge water reach the Chinese government and the IMO-MEPC107 of the international maritime Environmental Protection Committee (49) resolution emission standard through absorption and membrane sepn.
Background technology
At present, known oily-water seperating equipment is made up of one-level water-and-oil separator, spiral pump (ram pump), oil content concentration alarm record instrument, electric control box, magnetic valve, secondary oil in water emulsion separator etc., but make generally have only 150 hour the work-ing life of secondary oil in water emulsion separator like this, not only improve cost, and safeguarded inconvenience.
Summary of the invention
In order to address the above problem, the invention provides a kind of oily-water seperating equipment, this device adopts bag type filtering to separate the mode that combines with the vacuum membrane type, sewage by vacuum inhalation device body after, pass through gravity separation, pass through filter bag and membrane sepn more respectively, finally discharge water quality and can reach tap water quality.
The present invention has adopted following technical scheme: a kind of oily-water seperating equipment, it comprises strainer, the one-level water-and-oil separator, spiral pump, oil content concentration alarm record instrument, magnetic valve, secondary oil in water emulsion separator, strainer) inside with the one-level water-and-oil separator is connected, the one-level water-and-oil separator comprises the gathering room at top and the coalescer of bottom, bottom at the one-level water-and-oil separator communicates with the screw rod pump intake, be provided with T-valve in the spiral pump exit, first valve port of T-valve is connected with the spiral pump outlet, the spiral pump outlet is connected with oil content concentration alarm record instrument by second valve port, it also comprises filter bag oily-water seperating equipment, the screw rod pump outlet is connected with the import of filter bag by the 3rd valve port, be connected with secondary oil in water emulsion separator on the filter bag, the lower inlet of oil in water emulsion separator and the outlet of filter bag are joined, and the outlet on the top of oil in water emulsion separator is connected with oil content concentration alarm record instrument.
Be provided with the high precision fiber filter cloth in the described filter bag, fiber filter cloth is connected with filter bag by screw thread, also is provided with electric contact pressure in filter bag.
The invention has the beneficial effects as follows: the present invention adopts filter bag to make sewage enter the processing of secondary oil in water emulsion separator then by filter bag earlier, can farthest prolong the work-ing life (extending to 2500 hours) of secondary oil in water emulsion separator like this by original 150 hours, and filter bag only need take out to clean and need not to change, and reduces cost, non-secondary pollution.The present invention can not only handle the lighter sewage of emulsification (one-level is handled qualified sewage and no longer changed second-stage treatment over to) with not wasting energy automatically, also can discern and effectively handle the serious sewage of emulsification (one-level is handled the serious sewage of underproof emulsification and changed the processing of secondary oil in water emulsion separator automatically over to) automatically.

Embodiment
As shown in Figure 1, the present invention 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, the present invention also comprises filter bag 4, be provided with the high precision fiber filter cloth in the filter bag 4, fiber filter cloth is connected with filter bag 4 by screw thread, in filter bag 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 filter bag 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 filter bag 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.Secondary oil in water emulsion separator is made up of oil in water emulsion separator and electro connecting pressure gauge that high precision fiber core and inner chamber are assembled with the micro-filtration element.Primary separator is made up of top gathering room and bottom coalescer.Bottom connecting screw rod pump inlet.
As shown in Figure 2, work of the present invention is as follows: in the drainage procedure of spiral pump 3 after primary separator 2 relief outlet place suction process, make and produce vacuum in the primary separator 2, limber water enters separator 2 internal divergence spouts through strainer 1 top suction/draining valve, carry out gravity separation, larger oil droplet is floating to the top gathering room, and 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 6 after filter bag 4 filters and proceed the micro-filtration separating treatment.The oily water that contains superfine small oil droplet and small suspended solid is after filter bag 4 filters, the clearance of the suspended substance in the sewage is reached more than 98%, and make filtered sewage enter oil in water emulsion separator 6 bottoms, by importing after several distribution openings in the oil in water emulsion separative element, after a small amount of sump oil is stopped by the element micropore, blowdown variable valve by 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 6 handling properties lost efficacy (more than 2500 hours), 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 primary 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.
