Specific embodiment
Describe the present invention below in conjunction with the accompanying drawings, the description of this part is only exemplary and explanatory, there should not be any restriction effect to protection scope of the present invention.
As shown in Figures 1 to 6 a kind of possesses sump oil storage and the soft bellows of advanced treating function enclose oily weir, is mainly made up of following sections：Bunker is removed in eddy flow oil skimmer 11, sump oil storage silo 12, one-level aeration storehouse 14, swash plate（It is multistage）15th, the part such as two grades of aeration storehouses 17, fine filtering storehouses 16 is constituted.Main body each unit（Except eddy flow oil skimmer 11）Outward appearance and general morphology are essentially identical, each deoiling function storehouse in oily weir 18, middle part, bottom weight area are mainly enclosed by the wave resistance at top and is constituted.
Oily weir is enclosed during inoperative, mode is stored up using close-coupled, on the premise of rapid deployment operation is easy to, is practiced every conceivable frugality and take up room, that is, realize larger companding ratio.
During operation, by associated construction specification, weir body first is carried out enclosing ring washer around greasy dirt leak point and is closed, i.e., be fully connected from beginning to end, it is to avoid sump oil overflows in junction.After enclosing oily weir integral arrangement in place, other low-pressure gas sources that the general air compressor machine 6 or ship that the general operations ship 7 coordinated using emergency area is provided can be provided, be inflated to enclosing oily weir Jing after pressure regulation is stable so as to rapid expanding to expected working morphology, and arrange it is vertical it is floating with when accident waters.Charge operation is divided into two parts：Top wave resistance encloses the inflation of oily weir 18 and main body bin inflation at different levels.The inflation on oily weir 18 is enclosed to top wave resistance, the shortest time can realize that weir is body formed, provide buffer time for follow-up main body bin inflation, it is ensured that preferably enclose the realization of oily non-proliferation function in the early stage.
After the body global formation of weir, in the presence of bottom weight ballast 21, even if under a certain degree of wind wave action, weir body also can keep substantially founding floating form, and this is to ensure that the premise that follow-up deoiling function is realized.The airlift load outline of counterweight ballast 21 is less than ideal value, in this case, it is possible to using reserved each tune weight preformed hole 19 according to the additional tune weight ballast 22 of actual condition, so as to realize ideal poised state.
The external resource needed during oil spilling process mainly has：General operations ship 7, mobile Oil sucking device 2（The small boat operation that live utilizable energy is coordinated）, oil suction connection flexible pipe 3, oil suction membrane pump 4, general air compressor machine 6 and other interim pipeline, valves etc..Above resource is easier to coordinate in place in each production platform or oil product ships that transport workspace.
After related preparation is ready, start oil suction membrane pump 4, ordered collection is carried out by interim ship operation movement Oil sucking device to enclosing the oil slick in oily weir trap, in the presence of oil suction membrane pump 4, sump oil, substantial amounts of seawater (or other Natural Waters), the mixture of partial air are transported to first order oil removing unit-eddy flow oil skimmer 11, and beginning order carries out the water-oil separating operation of each functional unit.
The first order：Eddy flow oil skimming technique
Oil mixture enters storekeeper 8 and enters in eddy flow oil skimmer 11 by sump oil, because fluid is through the supercharging of oil suction membrane pump 4, there is certain flow velocity, by the regulation to the oil phase outlet pipe road of eddy flow oil skimmer 10 and the water phase export pipeline valve opening of eddy flow oil skimmer 13, make fluid and progressively slowed down flowing with comparatively stable eddy flow state.Lightweight oil phase in mixture is under the synergy of buoyancy, entrained air bubbles carrying, eddy flow centrifugal force etc., quick narrow conduit wall displacement to top and nearby, most sump oil progressively shifts to the oil phase near exit of eddy flow oil skimmer 10, some is centrifuged to neighbouring channel wall, because its material is soft material preparation, possesses certain oil suction effect, the tiny oil droplets being centrifuged out can be made to be trapped in wall certain hour, during this period more little oil droplets are assembled successively, can be with the bigger oil droplet of the formation of more maximum probability.According to the fundamental characteristics of oil, in metastable flow field, bigger oil droplet is more conducive to the separation of water-oil phase.Through the process of this one-level, to most sump oil, especially in type oil droplet more can be separated sufficiently, the oil phase of high concentration sump oil mixture Jing eddy flows oil skimmer 10 outlet isolated goes to sump oil storage silo 12 and treats subsequent treatment.The water phase export pipeline of sewage Jing eddy flows oil skimmer 13 of preliminary de-oiling goes to one-level aeration storehouse 14 and further processes.
It should be added that, if scene satisfies the requirements, it is also possible to import compressed gas all the way before sump oil enters storekeeper 8, the suitable gas liquid ratio of control, on the basis of above oil removing effect, stable, reinforcing oil removal by air bubbling effect reaches and the akin efficient degreasing of cyclone air-flotation.
The second level：One-level oil removal by air bubbling technique
One-level aeration storehouse 14 is entered into through the water phase export pipeline of sewage Jing eddy flows oil skimmer 13 of the preliminary oil removing of the first order.In the relative narrow space formed by weir plate 25 in the silo wall and air supporting storehouse, the air with pressure imported by aeration pipe valve 5 enters into microbubble and makes in vesicle 24, compressed gas through it is micro- it is ventilative make blister wall after be dispersed into fine and closely woven micro-bubble, after being sufficiently mixed with sewage, float in approximate boiling-like.In the process, by detached less oil droplet larger oil droplet it is not easier and is polymerized to and under the rolling action of absorption minute bubbles thereon, floating upward quickly, so as to reach higher oil removal efficiency.
Sewage containing high concentration afloat gas continues to flow, after the deceleration unhurried current and flow field formalism of the oil skimming swash plate group 28 after, remaining being taken be able to sufficiently go up lift-off analysis in the current stabilization flow field in relatively large space after gas and oil is dropped in, and the dregs of fat progressively float, and form preferable oil removing gradient.For the oil droplet for having floated, Intercepting effect becomes apparent from oil skimming swash plate, can largely reduce caused by mixed flow oil slick back-mixing again, and improves the adaptability to surge interference.
The oil slick for having separated out will be deposited in the storehouse liquid level upper strata, extend with the operating time, and oil reservoir will be gradually thickening.Realize expected oil removing effect.
Consider to carry out liquid gassiness, be to ensure each storehouse level balance, in adjacent two silo roofs portion the anti-overflow oil balance tube 29 of gas phase is devised.Balance pipe is in " n " type, in the case that total liquid level arrive and pushed up in the storehouse, can avoid or slow down the oil spilling between storehouse, it is ensured that subordinate's treatment effect is stablized.
The third level：Swash plate oil removing process
The water port 30 that is connected enters into swash plate except bunker between the sewage Jing storehouses after the oil removal by air bubbling PROCESS FOR TREATMENT of the second level, as fluid enters more and more, in whole filling process, sewage is substantially at low speeds flow state, plus the technique swash plate except bunker series is a lot, there is provided the more sufficient sedimentation separation time.
The effect of oil removing is settled for reinforcing and slow down disturbance of the surge to fluid, being provided with each storehouse can promote the oil skimming swash plate group 28 of water-oil separating, more reasonably utilize this section of time of staying.
According to the requirement of marine oil overflow emergency processing, the built-in weir plate in each storehouse, swash plate are software material, will not increase substantially during storage and enclose oily weir integral thickness too much.After inflation or filling sea water shaping, swash plate, weir plate launch with the abundant expansion molding of warehouse, play its due effect.This point is innovative.
According to oily weir overall product requirement specification is enclosed, the product of various length can be customized to, in the case where Qian Hou two sections of specifications finalize the design almost, mainly meet actual demand by changing swash plate except the series of bunker.In follow-up explanation, will be according to liquid flow direction be carried out, by this section of swash plate except bunker is described as respectively（15-1）、（15-2）、…、（15-n）.All swash plates are essentially identical except bunker internal structure, are easy to industrialized production.To improve the flexibility of product design, quick links pipe valve structure can be designed with to be often separated by some units in the section.Illustrate, often save swash plate except bunker is assumed to 4 meters long, design per 5 sections and quickly connect at one, i.e., standard block segment length is 20 meters.In the case where other segment length are not considered, the series of products with 20 meters of length as gradient can be combined, such as 20 meters, 40 meters, 60 meters ... 200 meters.
For not expected oil spill accident scene, rational arrangement and method for construction can be formulated by making overall plans and coordinate resource, according to incident area diameter to be controlled, match suitable totality and enclose oily weir length, for field accident process more operable spaces are provided.
The fourth stage：Secondary air-floatation oil removing process
The segment process and one-level oil removal by air bubbling technique basic simlarity, main difference is that the process at different levels before processed sewage process, and its oil content has already decreased to relatively low degree.The oil product not now being precipitated yet is substantially with the presence of solubilised state, emulsification state and fine drop.Proceed normal temperature sedimentation, effect is very weak.It is to remove these remaining sump oils, reaches in the water in row sea containing oil standard, need to carry out secondary air-floatation, the water-oil separating of depth is carried out using more tiny flotation bubble and suitable gas liquid ratio.
Level V：Fine filtering oil removing process
In ideal conditions, oil removing process before should can reduce oil-containing value in water reaching or the extra large critical field of the row of being close to.But to improve the security of technique and avoiding indirect impact, spy increased fine filtering storehouse 16.
The storehouse is divided into into two relatively independent bins by separation layer 33 in fine filtering storehouse 16：Treat filter chamber 32 and strainer chamber 34.Separation layer 33 is water proof material, is to increase filter area, improves sewage treatment capacity, with form of uniform arrays perforate on separation layer 33, the taper filter bag of each perforate sewing one lengthening of connection.
The sewage of front-end processing is first into treating filter chamber 32, flows from the interior strainer chamber 35 of accurate filter bag 34 that the impurity such as sump oil drop and suspension is retained by filter bag, it is ensured that the higher water quality of strainer chamber 35.Reach the purpose for closing rule discharge.
The part-structure is designed as the quick type of attachment of single-stage, is easy to the filter element quick-replaceable to saturation absorption or series connection to increase level intensive filtration, it is ensured that dirty effect and ability at the totality of whole system.
Weir phosphor bodies part is designed as soft compression bin capsule by the present invention on the basis of tradition encloses oily weir, after inflating expanded, encloses oily weir in the case where basic mechanical enclosing is realized, has also been additionally provided huge appearance dirt space, creates looser operating condition.By the appropriate design to enclosing You Yan storehouses capsule internal structure, on the basis of soft material, wound new applications of the various oil-containing sewage treatment techniques in the field are realized.Sump oil water under settlement action, the sewage with oil after process can be reduced under row's seamark standard in the high efficiency oil-water centrifugation through the system and length, realize harmless row sea on the spot.Even if its treatment effect is not reaching to arrange seamark standard, the floating dust storage cabin that bottom line also can provide big volume for accident rescue provides huge cushion space to accident final process.
If the invention product can be popularized, emergency stock is standardized in each platform, ship, just can effectively control the diffusion of oil spill accident, reduce incident classification and pollution level, be that safety and environmental protection production escorts.
In the present invention, it is contemplated that oil spilling area by overall enclosing, do not possess it is extensive it is excessive in the case of, even if the water quality for processing above is not reaching to standard, trap inner side contaminated area can also be discharged into, the degree of contamination accident will not be changed, with higher operability.
It is such as temporarily below standard, it is also possible to pressurize exhaust is carried out by pressurize air bleeding valve 37 in tail end in the case of strict control discharge standard, emission control pipe valve 36 is closed, keep front end continuously to collect the paramount limit liquid level of sump oil water.The connected nozzle valve of all profits is closed, whole thoroughly envelope storehouse, all contaminants are entered and seal armed state up for safekeeping, it is ensured that scene carries on accident rescue and works.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
