Description

A kind of method that bio-fuel is prepared using oily sludge
Technical field
The invention belongs to sludge treatment field, and in particular to a kind of method that bio-fuel is prepared using oily sludge.
Background technology
Oily sludge is the solid waste of generation during oil exploitation, transport, refining and oily waste water treatment, main Ingredient is crude oil, water and mud, and oil content is usually between 10 ~ 50%.It is estimated that China produces nearly 3,000,000 tons of oily sludge per year, In the crude resources that contains be about 600,000 tons or so.The objects such as crude oil, wax, colloid in oily sludge in addition to containing a large amount of agings Outside matter, also containing poisonous and harmful substances such as a large amount of benzene homologues, phenols, also contain a large amount of pathogen in oily sludge in addition, post It is infested, as without being rationally effectively treated, can not only wasted petroleum resources, but also environment can be caused seriously to pollute.Closely Nian Lai, with the continuous improvement that national environmental protection statutory standard requires, law enforcement for environmental protection dynamics continues to increase, the pollution control of oily sludge System and recycling, it has also become perplex the problem of petroleum and petrochemical industry.
The processing for the oily sludge that Petroleum Production and process generate, is a global problem, many engineerings Technical staff and experts and scholars did unremitting effort thus, had also issued many fruitful achievements, but never Find a kind of relatively good processing mode.So the oily sludge generated at present for Petroleum Production and process, Duo Shuoqi Industry is still handled by the way of landfill, also has indivedual enterprises to carry out burning disposal；Enterprise also introduces or exploitation is new The pyrolysis oil removing of type, the method for then remanufacturing building materials.These above-mentioned methods, for the place of the oily sludge for the purpose of environmental protection For reason, pollutant transfer, the pollution problem without fundamentally solving oily sludge are actually belonged to.In recent years, exist Also there is very big progress, but be all confined to after oily sludge is dehydrated in terms of carrying out microbial fermentation processing to oily sludge, add Add and carry out solid fermentation processing after promoting fermentation preparation, the oily sludge petrochina class generated due to Petroleum Production and process Substance and other organic component contents are excessively high, are handled by simple disposable microbe fermentation method, are extremely difficult to preferably locate Manage effect.
The method of existing processing oily sludge domestic at present, has been summed up：Burning method, landfill method, pyrolysismethod and life Object improvement etc..Oily sludge has higher calorific value and preferable combustion characteristics, therefore can make because it contains a large amount of organic matter For the raw material of fuel, and apply in Industrial Boiler, but in practical application there is also it is certain the problem of：（1）Due to containing greasy dirt Mud contained substance type is more, and viscosity is very big, and the easy adhesion of body refuse that convection drying is formed is glued with coal dust auxiliary fuel etc. Bulk is easily formed during conjunction, granulating and forming is difficult, and fuel stability is poor, not only leverages its firing efficiency, but also inconvenient In transport and preserve.（2）A large amount of petroleum substance is remained in oily sludge, these substances are discharged into environment to environment It pollutes, even landfill is also inevitably caused because of leakage with the passage of time to local underground to fixed place The pollution of water can also cause the volatilization of a part of petroleum substance and pollute air because of the variation of weather and temperature.So Landfill disposal is actually a kind of irresponsible processing method that What the eye doesn't see, the heart doesn't grieve for；（3）Using microbiological treatment sludge all It is focusing on the disposal of oily sludge after being carried out dehydrating research, it is intended to dewatered oily sludge be carried out micro- Biofermentation, some opinion aerobic fermentations, some opinion anaerobic fermentations, but treatment effect are not fine, because greasy dirt is contained It ferments after mud dehydration, either using aerobic fermentation still using anaerobic fermentation, all because being needed in microbial life activity The exchange for the matter and energy wanted smooth can not carry out, and cause fermentation processes difficulty big, the reaction interval of oily sludge fermentation Spend low, treatment effect can not be played normally.
The practical mainly biomass molding fuel of biomass fuel（Biomass Moulding Fuel）, it is that agricultural are given up By crushing, mixing, squeezing, the techniques such as drying, various moldings are made as raw material in object（Such as blocky, graininess）, it can A kind of Novel clean-fuel directly to burn.High-grade energy form conversion is carried out using biomass as raw material, it is possible to reduce Dependence to energy such as oil and natural gas, and then Optimization of Energy Structure improve the degree of self-sufficiency of the energy, slow down the row of greenhouse gases It puts, reduces environmental pollution.Biomass fuel generally be mainly agriculture and forestry organic waste material, poultry manure, city organic solid castoff, Sanitary sewage and industrial organic waste water, the main distinction in fossil fuel, by special equipment under specific process conditions the system of processing Into the biomass fuels such as powdery, rodlike, blocky or graininess, the combustibility of agriculture and forestry organic waste material can be effectively improved, mating Special combustion device on apply, it can be achieved that cleaning, efficient burning.
Invention content
The technical problems to be solved by the invention：For current all process for treating oil-containing sludge, all there are certain environment The problem of polluting, and can not making full use of oily sludge, provides a kind of method that bio-fuel is prepared using oily sludge.
