Description
Technical field
The utility model belongs to petroleum refining field, especially the oily sludge drying and other treatment device of petrochemical enterprise.
Background technology
Oily sludge composition is extremely complex, is mainly made up of the mixing such as oil emulsion, water, solid suspension, oily sludge
Resistivity is bigger than general sludge 40 times, and its compressible coefficient is big 20 times, the difficult filterability sludge of category, and because its particle is tiny, is in
Floccule body shape, water content is high, bulky, therefore is difficult to realize the three phase separation of oil-water-mud.Because its property is special, contain
Greasy dirt is dehydrated and treatment technology difficulty is big, high cost, is always the difficult problem of environmental protection for perplexing China's oil refining industry.
Concentration, Chemical Regulation (i.e. quenched), dehydration be traditional disposal of oily sludge system pretreatment link.Concentration is divided into
Natural subsidence is concentrated and two kinds of mechanical agitation sedimentation concentration.The oily sludge of high-moisture can not directly carry out mechanical dehydration behaviour
Make, it is necessary to first carry out quenched.It is quenched generally to be carried out in concentration basin or concentration tank.Sludge dewatering generally uses mechanical dehydration.It is dirty
Mud dewatering machine mainly has drum type vacuum filter, bend-band formula rotary drum vacuum filter, disc type filter, sheet frame pressure
Filter, belt filter press and centrifugal dehydrator etc..Centrifugal dehydrator is used petrochemical enterprise more.
Oily sludge after dehydration also needs to further carry out harmless treatment, generally can using burning method, pyrolysismethod and

Discharge is few, and can reclaim a part of petroleum resources, but its energy consumption is higher, and technique is more complicated, constrains its popularization.Microbial method
Treatment oily sludge is to utilize microorganism in growth metabolism by the sludge petrochina hydrocarbon conversion into CO2And H2O or other are harmless
The process of material, generally take up an area it is big, it is necessary to time it is more long and poor to the Treatment of Sludge effect of oil-containing high.
Oily sludge moisture content is higher, and high-moisture percentage can cause sludge imperfect combustion in incinerator, oily sludge
It is necessarily required to pre-process link by dehydration, desiccation etc. before burning control the moisture content and calorific value of oily sludge.Oil
The oily sludge moisture content such as work enterprise greasy filth, scum silica frost are often 99%, are concentrated through natural subsidence, and moisture content can typically be down to about
97%, 70%~80%, oil content is about 5%~15% to moisture content after mechanical dehydration.Through the sludge after mechanical dehydration also
Need to carry out drying and other treatment, further drying and other treatment, moisture percentage in sewage sludge is reduced, to improve burning disposal efficiency.
