The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1: a kind of oil removal water trap, comprises that described housing 26 is divided into filtration chamber's part, separation chamber's part and water seal return passage part by dividing plate I 25 and dividing plate II 27 with the housing 26 of inlet short pipe 5 and outlet short tube 7.Described filtration chamber part comprises filtration chamber 1, and inlet short pipe 5 entrance point places are provided with suction flange 6, and the filter basket 8 with filter basket handle 10 is installed on the inwall communicating in inlet short pipe 5 and filtration chamber 1, in dividing plate I lower end, offers inlet 9; Described separation chamber part comprises separation chamber 2,2 bottoms, separation chamber are provided with the solid conical 12 of handstand, solid conical 12 upper ends connect the hollow ball 11 with filling tube 15, hollow ball 11 is provided with main buoyancy aid handle 16, main buoyancy aid pallet 13 with soft seal ring 14 is installed on separation chamber's 2 inwalls, solid conical 12 drops on the main buoyancy aid pallet 13 of 2 bottoms, separation chamber, offers pod apertures 18 and liquid outlet 17 in dividing plate II; Described water seal return passage partly comprises the water seal return passage 3 with outlet short tube 7, connects the mozzle 19 of pod apertures 18 in the interior installation of water seal return passage 3, and mozzle 19 other ends are connected with ball valve 20, control lever 21 and small floating ball 22 in turn.In described housing 26 upper ends, the upper cover plate 4 with peep-hole 23 and cover plate handle 24 being installed, make operator can observe ball float and indoor oil-containing situation.

The course of work: during oil leak accident, stop oil product outflow, oil removal process.When a large amount of leakage occurs in tank area petroleum liquid product, leak oil product and enter into oil removal water trap through the sewage vent line under fire wall.First, oil product progresses into filtration chamber 1 through inlet short pipe 5, and along with the continuous increase of oil product, the liquid level of oil product in filtration chamber 1 constantly raises, and when arriving inlet 9 position, oil product can flow in separation chamber 2 by inlet 9; Secondly, along with the liquid level of oil product in separation chamber 2 constantly raises, due to hollow ball 11 and 12 two main buoyancy aids that partly form of solid conical, the gravity in oil product is greater than its suffered buoyancy, main buoyancy aid can steadily drop on main buoyancy aid pallet 13, the soft seal ring 14 of main buoyancy aid and main buoyancy aid pallet 13 keeps excellent sealing, therefore oil product can not flow into main buoyancy aid tray bottom, but when oil product rises to certain altitude, can flow in mozzle 19 by the pod apertures 18 on separation chamber's 2 inwalls, and then oil product is entered in water seal return passage 3; Finally, the oil product flowing in water seal return passage 3 can be back to interior entity taper 12 bottoms, separation chamber 2 by liquid outlet 17, make to be full of oil product in winner's buoyancy aid pallet 13 lower space, when oil product rises to certain altitude in water seal return passage 3, ball valve 20 can be closed automatically, thereby oil product cannot be flowed in water seal return passage 3 by mozzle 19, thereby stop oil product to leak in a large number, realized and stoped oil product to outflow, prevent that oil product is through the wandering effect of blow-off line.

Process the not drainage procedure of oil-polluted water.Not oil-polluted water in the fire wall of tank field enters filtration chamber 1 when interior through inlet short pipe 5, and the impurity in sewage can be isolated in filter basket 8 inside, and the liquid level in Shui filtration chamber 1 raises gradually, when rising to inlet 9 position, can flow in separation chamber 2.Along with water level slowly raises, the main buoyancy aid consisting of hollow ball 11 and solid conical 12 is still because gravity reason stops to main buoyancy aid pallet 13.Main buoyancy aid and soft seal ball 14 keep good contact, and water can not leak.Water level in separation chamber 2 gradually rising can make water flow into mozzle 19 and ball valve 20 by pod apertures 18, finally flow to water seal return passage 3 bottoms.In water seal return passage 3, rising along with water level, small floating ball 22 gravity can be less than suffered buoyancy of water, float at leisure, thereby make control lever 21 drive small floating balls 22 to rise, water can be back to main buoyancy aid pallet 13 bottoms by liquid outlet 17 simultaneously, when this space is full of water, main floating body gravity in separation chamber can be less than its suffered buoyancy, thereby makes main buoyancy aid automatically separated with main buoyancy aid pallet 13, and main buoyancy aid floats; The gap of the water in separation chamber 2 between solid conical 12 and main buoyancy aid pallet 13 portion into its next now, flows into the bottom of water seal return passages 3 through liquid outlet 17, when water level is elevated to a certain degree, ball valve 20 is closed automatically, and water cannot be from the interior outflow of pod apertures 18.Thereby make water enter water seal return passage 3 by the bottom of solid conical 12 and main buoyancy aid pallet 13, then through the normal draining of outlet short tube 7.

Oil removal drainage procedure while processing oil-polluted water.When oil-polluted water is after inlet short pipe 5 enters filtration chamber 1, after filtering because oil ratio water is light, in filtration chamber, 1 interior liquid level can slowly raise oil water mixture, oil is all the time on top, interior bottom, Shui filtration chamber 1, finally by inlet 9, enter in separation chamber 2, main buoyancy aid does not float, in separation chamber, 2 profits when interior are still stratification state to profit, oil in the above, water below, when profit reaches pod apertures 18 position, in profit, most water can be through mozzle 19, ball valve 20 enters in water seal return passage 3, along with water refluxes and is full of separation chamber 2 this process of interior solid conical 12 bottom spaces through liquid outlet 17, main buoyancy aid can float gradually, separation chamber 2 flow channels is from down to up slowly open-minded, upper water in separation chamber 2 can enter water seal return passage 3 bottoms through liquid outlet 17 by the passage between solid conical 12 and main buoyancy aid pallet 13, small floating ball 22 rises gradually, ball valve 20 when last water level reach a certain height under mozzle 19 is closed.At this moment overwhelming majority oil is at the upper space that is isolated in separation chamber 2, in separation chamber 2, passage is from top to bottom drainage channel, when the water in sewage conduct is after 7 emptyings of outlet short tube, once the lower space that oil enters solid conical 12, main buoyancy aid can close, and oil can not flow out.Thereby realize oil resistance drainage procedure.

Stop drainage pipe flame propagation process.When having enough water gagings by oil removal water trap, in water seal return passage 3, will keep certain water level, little buoyancy aid 22 floats, and ball valve 20 is in closed condition, and middle and lower part pod apertures 18 these flow-guiding channels that separation chamber 2 arrives water seal return passage 3 are in closed condition; Water seal return passage 3 is water abrim to the return flow line, bottom between separation chamber 2; When the water yield continues to increase again, the water level in water seal return passage 3 can arrive the position of outlet short tube 7.Flame cannot enter in tank field by water seal layer of the present utility model through outlet short tube 7 adverse currents, thereby guarantees oil product storage safety, plays the flame propagation effect that stops.

Line service.Whether operating personnel can have oil product in filtration chamber 1, separation chamber 2 and water seal return passage 3 by peep-hole 23 observation oil removal water traps, if there is oil product, should ascertain the reason in time.Filter basket 8 in finding filtration chamber 1 is crossed when dirty, can mention cover plate handle 24, thereby open upper cover plate 4, mention filter basket handle 10, filter basket 8 can be proposed to filtration chamber 1, after cleaning treatment is clean, again put back to again, twist the associated bolt on good upper cover plate 4.
