The oil skimmer is mainly used for skimming oil in the water-sealed tank of a flare system in oil refining and chemical enterprises.
Description
Technical field
The utility model relates in oil refining and chemical enterprise for a kind of water sealed tank skimming plant of flare system water sealed tank.
Background technology
The flare system of most domestic oil refining and chemical enterprise adopts the mode of water sealed tank fluid-tight to stop flare system tempering, avoids the equipment of flare system discharge pipe network and connection thereof to wreck.Flare system water sealed tank is after operation after a while, and flare discharge gas is due to reasons such as temperature drops, and part heavy constituent can separate out formation condensed oil from flare discharge airsetting.Because the proportion of condensed oil is less than water, will swim on the water seal liquid level of water sealed tank, when torch generation tempering, easily there is burning and blast.Therefore the condensed oil, gathering on the timely skim water sealed tank water surface seems particularly important.
The water sealed tank skimming plant adopting is at present that the several fixedly liquid levels at water sealed tank arrange oil skimming opening, and each oil skimming opening is connected with an oil skimming pipe, and oil skimming pipe is provided with valve.This device only can exist oil skimming dead band between adjacent two oil skimming openings in several fixing liquid level oil skimmings, is difficult to realize in the liquid level of differing heights, carry out continuously oil skimming operation.Therefore the condensed oil that existing water sealed tank skimming plant accumulates on skim water sealed tank liquid level in time; When flare system tempering, exist the danger of burning and blast.
Summary of the invention
The purpose of this utility model is to provide a kind of water sealed tank skimming plant, to solve the problem of the condensed oil accumulating on the existing skim in time of existing water sealed tank skimming plant water sealed tank liquid level.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of water sealed tank skimming plant, it is characterized in that: it comprises oil skimming standpipe, floating thing, oil skimming broken pipe and oil skimming transverse tube, floating thing at least arranges 4 around oil skimming standpipe on horizontal plane, each floating thing is connected with oil skimming standpipe by a connecting plate, the top of oil skimming standpipe is oil skimming mouth, between the entrance of the outlet at bottom of oil skimming standpipe and oil skimming broken pipe, be connected by swivel coupling respectively between the outlet of oil skimming broken pipe and the entrance of oil skimming transverse tube, oil skimming transverse tube is provided with valve.
Adopt the utility model, there is following beneficial effect: when (1) the utility model is worked in water sealed tank, can select as the case may be the quantity of floating thing, make the own wt of oil skimming standpipe, floating thing, connecting plate and the oil skimming broken pipe buoyancy suffered with it in poised state, and utilize condensed oil, sealing water to have the principle of difference in specific gravity, make oil skimming standpipe with the variation of liquid level in the water sealed tank lifting of floating, the oil skimming mouth of the oil skimming riser top when various height of the liquid level in water sealed tank can be all the time in oil-water interfaces place.Condensed oils more than oil-water interfaces can enter oil skimming mouth continuously, in time, by oil skimming standpipe, oil skimming broken pipe, oil skimming transverse tube, discharges water sealed tank, thus the danger of the burning existing while effectively preventing flare system tempering and blast.(2) of the present utility model simple in structure, invest littlely, oil skimming operating process is easy and safe and reliable.
The utility model is mainly used in the oil skimming of torch system water sealed cans in oil refining and chemical enterprise.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.The drawings and specific embodiments do not limit the claimed scope of the utility model.
Accompanying drawing explanation
Fig. 1 is that the utility model water sealed tank skimming plant is installed on the schematic diagram in water sealed tank.
Fig. 2 is the top view (amplification) of oil skimming standpipe, connecting plate and floating thing in the skimming plant of water sealed tank shown in Fig. 1.
In Fig. 1 and Fig. 2, same reference numerals represents identical technical characterictic.
The specific embodiment
Referring to Fig. 1 and Fig. 2, water sealed tank skimming plant of the present utility model comprises oil skimming standpipe 7, floating thing 5, oil skimming broken pipe 8 and oil skimming transverse tube 9.Oil skimming standpipe 7 is one section of short tube vertically arranging; Floating thing 5 at least arranges 4 around oil skimming standpipe 7 on horizontal plane, and each floating thing 5 is connected with oil skimming standpipe 7 by a connecting plate 6.The top of oil skimming standpipe 7 is oil skimming mouth; Between the entrance of the outlet at bottom of oil skimming standpipe 7 and oil skimming broken pipe 8, be connected by swivel coupling 12 respectively between the outlet of oil skimming broken pipe 8 and the entrance of oil skimming transverse tube 9.Oil skimming transverse tube 9 is horizontally disposed with, and which is provided with valve 10.
Described floating thing 5 is generally floating drum or ball float, around oil skimming standpipe 7,4～8 (what shown in Fig. 2, arrange is 8) is evenly set.The oil skimming mouth at described oil skimming standpipe 7 tops is preferably provided with screen cloth 70, to avoid foreign material to enter oil skimming standpipe 7.
On described oil skimming transverse tube 9, be preferably provided with and observe visor 11, to observe the flow condition of oil skimming transverse tube 9 interior condensed oils.
Referring to Fig. 1, the utility model is arranged in existing water sealed tank 1 in use.Water sealed tank 1 can be horizontal tank (as shown in Figure 1) or vertical tank (figure slightly), which is provided with flare discharge gas inlet duct 2 and flare discharge gas outlet conduit 3, and sealing water (Reference numeral 4 in Fig. 1 represents oil-water interfaces) is housed in tank.The entrance of flare discharge gas inlet duct 2 is connected with process unit, and the outlet of flare discharge gas outlet conduit 3 is connected with torch.The utility model when mounted, should be as far as possible away from flare discharge gas inlet duct 2, and between other inner member in assurance and water sealed tank 1, leaves safe spacing, avoids collision.Oil skimming transverse tube 9 is generally the position in water sealed tank 1 bottom and stretches out from water sealed tank 1; Valve 10, observe visor 11 and be installed on the pipeline section that oil skimming transverse tube 9 stretches out from water sealed tank 1.
The utility model is when water sealed tank 1 interior work, can select as the case may be the quantity of floating thing 5, make the own wt of oil skimming standpipe 7, floating thing 5, connecting plate 6 and oil skimming broken pipe 8 buoyancy suffered with it in poised state, and utilize condensed oil, sealing water to have the principle of difference in specific gravity, make oil skimming standpipe 7 with the variation of the water sealed tank 1 interior liquid level lifting of floating, the oil skimming mouth at oil skimming standpipe 7 tops when various height of the liquid level in water sealed tank 1 can be all the time in oil-water interfaces 4 places.More than 4 condensed oil of oil-water interfaces enters oil skimming mouth continuously, in time, by oil skimming standpipe 7, oil skimming broken pipe 8, oil skimming transverse tube 9, discharges water sealed tank 1, enters airtight condensed oil system.
