Abstract
The invention relates to a harmless treatment method of oil sludge through extraction assisted by dry distillation. The method comprises the steps of auxiliary extraction process of oil sludge and dry distillation process, and comprises the following specific steps: mixing an extraction agent with oil sludge according to the weight ratio of (0.5-1): 1; stirring and mixing for 10 minutes at the temperature of 20-80 DEG C; carrying out standing for 10-20 minutes to obtain upper oil phase and a lower extraction residue sludge mixture; separating out upper oil; distilling lower residue sludge; drying to obtain sludge powder; introducing the sludge powder into a rotation type dry distillation furnace for dry distillation. According to the harmless treatment method, dry distillation is the core, but when dry distillation is directly carried out on oil sludge, a coking phenomenon is caused due to the situation that oil sludge easily adheres to the furnace wall, and the normal operation of the dry distillation furnace is influenced; oil sludge subjected to auxiliary extraction avoids coking, and the dry distillation furnace can continuously runs; besides, in the method, other chemicals are not added except a small amount of the extraction agent, so that secondary pollution is avoided, and the extraction agent can be recycled.
Description
Technical field
The present invention relates to oil-sludge treatment field, be specifically related to a kind of greasy filth method for innocent treatment extracting auxiliary destructive distillation.
Background technology
Greasy filth refer to oil exploitation, collect defeated, the oil-containing black solid, the semisolid waste that produce in refining and oily water treatment process, its main component is crude oil, Ni Heshui.At present, both at home and abroad for the process of greasy filth, Preliminary Exploitation goes out a series of technology.Existing oil-sludge treatment technology respectively has relative merits, and the scope of application having it certain, and mostly there is Technical comparing complexity, thus and be not exclusively applicable to the resource utilization of distillation system's greasy filth and innoxious economic treatment oily resource recycling rate in the high and greasy filth of long flow path, cost is low or obtain the defects such as high-quality oil product is more difficult.
More typical, apply more process for treating oil-containing sludge and have several as follows: one, modified-dehydration: this technique is simple, processing condition are gentle, recyclable part crude oil, but after process, the oleaginousness of mud cake is still higher, do not reach emission standard, need to process further.Two, solvent extraction: this technological process selectivity is high, is easy to continuous operation, requires that solvent usage ratio is comparatively large usually, though recyclable most of solvent, but generally in operating process solvent loss larger.Three, solidification method: simple, but the mud after solidification is stacked and is taken big area soil, and add organic curing agent and may bring secondary pollution.Four, burning method: the multiple harmful substances in mud almost all removes, decreases the harm to environment, but cost and process cost higher, can not crude oil be reclaimed, and burn the sulfurous gas, carbon monoxide and the dust that produce and easily secondary pollution is produced to air.Five, biological process: easy to operate, final product is carbonic acid gas and water, and non-secondary pollution, does not need heat, and processing cost is low.But the treatment time is longer, can not crude oil be reclaimed, cause the waste of resource.
Summary of the invention
The object of the present invention is to provide a kind for the treatment of process of oily sludge.This technique has used for reference feedstock hydrocarbon dry distillation reactor device and method for destructive distillation, in order to meet the requirement of destructive distillation device to raw material, adopt solvent pre-treatment, effectively reduce greasy filth viscosity, avoid coking in retort process, reclaim the part crude oil in greasy filth, the quantity of solvent used in process, much smaller than the solvent-extracted solvent load of greasy filth of routine, effectively avoids solvent loss simultaneously.Greasy filth after pre-treatment, send into rotary retort and carry out low-temperature pyrolysis, destructive distillation obtains remaining water, oil and residue.Residue oil length is extremely low, can reach the emission standard (oil length <0.3%) of regulation.
The technical solution adopted in the present invention is: a kind of greasy filth method for innocent treatment extracting auxiliary destructive distillation, comprise the following steps: the extraction pre-treatment of (1) greasy filth: extraction agent is joined in greasy filth, the extraction agent wherein added and the weight ratio of greasy filth are 0.5-1:1, stirring and evenly mixing at 20-80 DEG C, standing 10-20min, obtains upper oil phase after leaving standstill and lower floor extracts residual mud; (2) extract the low-temperature pyrolysis process of residual mud: will extract the distillation of residual mud dry, and obtain dry mud powder, send into rotary retort and carry out destructive distillation, destructive distillation temperature rise rate is 5 DEG C/min, destructive distillation final temperature 500-550 DEG C.By the oil after destructive distillation, Water Sproading, gained destructive distillation body refuse meets emission standard.
