Description
Technical field
The utility model relates to a kind of tank cleaning treating apparatus, relates in particular to a kind of cleaning processing apparatus that is used for large oil tank.
Background technology
For the storage tank of storing oil product; In the storage of oil product long period, heavy oil property components such as all kinds of small amount of impurities, the grains of sand, earth, heavy metal salt and paraffin, pitch can be accumulated in tank bottom because of the difference in specific gravity natural subsidence, form not only black but also thick colloid substance layer; Be called the oil tank bed mud; Generally need when the regular oil tank in 5 to 6 years cleans at interval, it to be gone out clearly outside the jar, its quantity generally can be up to 1%～2% of this tank capacity.The oil tank bed mud is different from general oily sludge, has very high hydrocarbons content, is a kind of resource of good recyclable utilization; Find through long-term investigation test, contain inorganic matter such as the silt particle of have an appointment 25% water and 5% etc. in the oil tank bed mud, all the other 70% for hydrocarbon (wherein asphalitine accounts for 7-8%; Paraffin accounts for 6%; Ash accounts for 48%), contain contents of many kinds of heavy metal ion and poisonous and hazardous organic matter in the greasy filth simultaneously, if the oil tank bed mud is not taked efficient resourceization, minimizing and harmless treatment; With causing a large amount of petroleum resources to run off, simultaneously environment is polluted.
China's oil tank bed mud is removed main artificial removing of adopting at present, also has minority to adopt mechanical removal.But along with a large amount of construction of Chinese large-sized petroleum storage tank and the needs of safety in production, and to the pay attention to day by day of environmental protection problem, artificially remove the objective requirement that the oil tank bed mud has not met environment and development.
The artificial oil tank bed mud of removing mainly comprises slack tank, steaming jar, ventilation, gas inspection, advances people, release, the other treatment and other steps of greasy filth.When oil tank reaches clearly jar, in limited time, at first oil product in the jar is as far as possible all extracted, inject proper amount of clear water then and feed steam; Promptly so-called " steaming jar "; After being heated to uniform temperature, the part oil product just floats to the top layer from the emulsus bed mud, with pump the top layer oil product is extracted then; Accomplish once " steaming jar " like this and handle, adopt usually twice or twice above " steaming jar " processing; After " steaming jar " processing, open manhole and carry out gravity-flow ventilation or forced ventilation, simultaneously tank bottom is flushed clean-out hatch and open; Let the profit and the part bed mud that can flow flow into the other storage mud groove of oil tank certainly; After treating that gravity flow finishes, from jar, gather gas appearance again, surveying quick-fried qualified back operating personnel can get into from manhole; Carry out the clear mud of manual work, handle jar interior all deposits as the dregs of fat.The shortcoming of artificial clear mud is: removing bed mud because of manual work all is to adopt manually-operated, and construction period is longer, cleans one 50,000 side's oil tank, generally needs 45～50 days, and manual work has high input, labour intensity is big; Poor stability, crude oil recovery rate are low; The bottom settlings thing is all handled as the dregs of fat, caused ample resources waste and environmental pollution.
In 1997, China Petroleum Pipeline Bureau introduced the first cover oil tank machinery cleaning equipment (C0W equipment), has from then on opened the crude oil in China storage tank and has carried out the precedent that machinery cleans.As shown in Figure 1; Mechanical removal oil tank bed mud is to utilize the cleansing medium of washer jet with uniform temperature, pressure and flow, is ejected into the surface that is cleaned in the oil tank, removes the coagulation and the stasis of blood slag of surface to be cleaned; Make and form the husky bed mud of profit at tank bottom; Utilize such as aspirators such as elevator pumps then the bed mud in the oil tank is pumped out, enter into subsequently and reclaim the sand that oil tank filters out bed mud, remaining profit carries out water-oil separating through scavenging pump: sewage is driven into heat exchanger and heats; Be ejected in the oil tank by washer jet again, use as cleansing medium; Profit is driven into the oil skimming pipe, further precipitated and separated, and upper strata oil is recovered, and the sewage of bottom is passed into scavenging pump and carries out water-oil separating once more.With respect to artificial blue mud, mechanical blue mud has certain advantage, but still has following shortcoming: 1, the cleansing medium consumption is big, promptly causes energy loss, also causes the subsequent treatment liquid measure to increase; 2, cleansing medium employing hot water or diesel oil, reasonably cleaning temperature is confirmed difficulty, the too high jar interior emulsification of crude oil that causes easily, crossing to hang down influences cleaning performance again, and the greasy dirt of tank skin can't be dispeled fully; 3, oil tank still has the part dead angle thoroughly to clean, and needs artificial the entering to clean; 4, the sand that goes out does not clearly separate jar end, can't reclaim hydrocarbon; 5, it is moisture very high to efflux bed mud, and environmental pollution is serious.
At present crude oil in China storage tank machinery cleaning technique is in the starting stage with equipment research, and state's inner storage tank machinery cleaning only limits to the profit slag in the jar etc. is cleared out, and it is not done further processing.How storage tank machinery being cleaned to handle with the profit slag and combine, reach and efflux or reclaim requirement, is the emphasis of the mechanical Development for Cleaning Technique of storage tank after China.
