Description
Technical field
The present invention relates to a kind of oily bilge water treatment system., relate in particular to the liquefaction of a kind of FLRSU(natural gas liquids and regasify device) the heavy-hydrocarbon oil Sewage treatment systems.
Background technology
To the enhancing of marine environmental protection consciousness, also more and more stricter for the control of sea discharge along with in the world.And FLRSU not only has conventional turbine equipment can produce oily water, carry out in addition the sump oil water that the equipment of gas conditioning can produce, and contain the heavy hydrocarbon composition that can not use conventional oil and water treatment equipment to be processed in this kind of oily water, if utilize conventional oily-water seperating equipment to be separated this class oily water, isolated water can not meet the requirement of MARPOL effluent specification.
Summary of the invention
To the objective of the invention is in order overcoming the above problems, a kind of system that can process this kind of particular oils sewage to be provided, guarantee that discharge can meet code requirement.
The technology of the present invention thinking is: the oily water that distinct device is produced is divided into two to be processed, a kind of is that conventional equipment produces, and by its cabin of releasing, adopts conventional oily water separating equipment to be processed, qualified water after processing is directly arranged outboard, the sump oil dregs of fat cabin of releasing; The oily water that contains heavy hydrocarbon that another compressor unit treatment facility produces, the greasy dirt water tank of releasing and newly increasing, after special separating device separates, qualified water is directly arranged outboard, and isolated heavy hydrocarbon is discharged into the heavy hydrocarbon cabin.
Technical scheme of the present invention is: a kind of FLRSU heavy-hydrocarbon oil Sewage treatment systems comprises oil drain pan, hold well, plumbing for waste water, upperdeck greasy dirt water tank, circulating tube a, circulating tube b, circulating tube c, circulating tube d, circulating tube e, circulating tube f, all be provided with valve on above-mentioned circulating tube, also comprise the upperdeck water-and-oil separator, the heavy hydrocarbon cabin, one end of described plumbing for waste water connects oil drain pan, the other end connects the top of upperdeck greasy dirt water tank, the end of described circulating tube a connects the bottom of upperdeck greasy dirt water tank, the other end is connected with the end of circulating tube b and circulating tube c, the other end of circulating tube b is connected on described upperdeck water-and-oil separator, the other end of circulating tube c is connected in hold well, described circulating tube d is arranged on the bottom of upperdeck water-and-oil separator, the end of described circulating tube e is arranged on the top of upperdeck water-and-oil separator, the other end is arranged on the heavy hydrocarbon cabin, the end of described circulating tube f is arranged on the upperdeck water-and-oil separator, the other end is arranged on the top of upperdeck greasy dirt water tank.
This design has not only solved the problem that general device can not be processed heavy hydrocarbon, again can by heavy hydrocarbon retrieve realize the protection to environment, can also obtain extra economic benefit.
The accompanying drawing explanation
One-piece construction figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
Sewage treatment systems of the present invention, oil drain pan 14 is for collecting the oily water containing heavy hydrocarbon that on main deck, compressor unit 15 produces as high pressure flash vapour pressure contracting unit, low pressure flash vapour pressure contracting unit, reliquefaction installation compressor unit; The oily water that hold well 13 produces and reveals for collecting other equipment; Plumbing for waste water 1 is delivered to upperdeck greasy dirt water tank 2 for the oily water by oil drain pan 14; Upperdeck greasy dirt water tank 2 is for storing containing heavy-hydrocarbon oil sewage; Circulating tube a3, circulating tube b4, circulating tube c5, circulating tube d6, circulating tube e7, circulating tube f8, carry for oily water being managed throughout to equipment room, all is provided with valve on above-mentioned circulating tube, is convenient to control flowing of oily water; Upperdeck water-and-oil separator 9 is for being processed heavy-hydrocarbon oil sewage; The heavy hydrocarbon that separate for collection in heavy hydrocarbon cabin 10; One end of described plumbing for waste water 1 connects oil drain pan 14, and the other end connects the top of upperdeck greasy dirt water tank 2, is arranged on top and is convenient to the greasy dirt cabin and can obtains utilizing the most efficiently; The end of described circulating tube a3 connects the bottom of upperdeck greasy dirt water tank 2, is convenient to discharge oily waters all in the greasy dirt cabin; The other end is connected with the end of circulating tube b4 and circulating tube c5, and the other end of circulating tube b4 is connected on described upperdeck water-and-oil separator 9, and the other end of circulating tube c5 is connected in hold well 13; Described circulating tube d6 is arranged on the bottom of upperdeck water-and-oil separator 9, for the water after processing, discharges outside ship side; The end of described circulating tube e7 is arranged on the top of upperdeck water-and-oil separator 9, and the other end is arranged on heavy hydrocarbon cabin 10, for isolated heavy hydrocarbon is delivered in heavy hydrocarbon cabin 10; The end of described circulating tube f8 is arranged on upperdeck water-and-oil separator 9, the other end is arranged on the top of upperdeck greasy dirt water tank 2, upperdeck water-and-oil separator 9 is provided with the sump oil detection system, the clean water that reaches emission request after processing is directly arranged outboard, and below standard oily water returns upperdeck greasy dirt water tank 2 by circulating tube f8 automatic-discharging.
