Description
Technical field
The invention belongs to the solid waste process field, be specifically related to recycling treatment method of oil-bearing sludge.
Background technology
China is as maximum in the world developing country and oil production big country, and working condition, Pollution control technology are backward relatively.A large amount of oily sludges have been produced Oil extraction, defeated the reaching in the refining process of collection.According to estimates, China produces nearly 3,000,000 tons of oily sludge per year, and the oily sludge of only grand celebration, triumph, the annual output of the Liaohe River three elephants just reaches more than 2,000,000 tons.And the most of oil fields of China have all entered high moisture, high oil recovery rate, high recovery percent of reserves " three height " stage in period, and along with the increase of water injection rate, the oily sludge growing amount also increases thereupon.
Oily sludge also contains a certain amount of crude oil except that containing silt particle and water, the existence of this part crude oil not only makes greasy filth have environmental hazard, is classified as Hazardous wastes; And make greasy filth have the potentiality of recycling.But oily sludge has that to form fluctuation big, and heavy components content is higher in the oil content, makes this part oil separating reclaim very difficulty.
The thermal desorption technology is as a kind of heat treatment technics, have recyclable resource, adaptability strong, handle thoroughly, the little characteristics of secondary pollution.When it is applied to oily sludge and handles, can realize separating of oil content and silt particle.But the processing cost of thermal desorption is higher, and the oil content that obtains is based on heavy component, and quality is lower, and the economy that has caused the oily sludge thermal desorption to handle thus is relatively poor.
Therefore, a kind of not only economy of exploitation but also can reclaim the process for treating oil-containing sludge that obtains high-quality oil content and have important economy and social effect.
Summary of the invention
Oil that exists at present process for treating oil-containing sludge and silt particle inferior separating effect, the problem that the refiltered oil quality is low the invention provides a kind of convenience, energy-conservation, efficient, economic process for treating oil-containing sludge.
Process for treating oil-containing sludge provided by the present invention comprises the steps: that earlier oily sludge being carried out thermal desorption under oxygen free condition handles, and obtains the oil content in the described oily sludge; Then described oil content is carried out catalyse pyrolysis under oxygen free condition, the gas of separating out carries out oil, gas, water sepn after condensation, collects oil and gas.
Wherein, the temperature that described thermal desorption is handled can be 500 ℃～550 ℃, and the treatment time can be 30min～45min.The temperature of described catalyse pyrolysis can be 450～550 ℃, and the time can be 1s～10s.
When described oil content was carried out catalyse pyrolysis, the catalyzer of use can be siliceous and material aluminium.In order further to reduce the oily sludge processing cost, can select solid waste such as flyash, the slag etc. of generation silicon-aluminum containing big, that obtain easily, as the catalyzer of above-mentioned catalyse pyrolysis.
With aforesaid method oily sludge is handled, be rich in CH in the gas that obtains
4With H
2, calorific value is higher, can be used as the fuel of heat supply of thermal desorption and catalyse pyrolysis, is system's heat supply by the burning release of heat, realizes the internal recycling utilization of system capacity; The refiltered oil that obtains (resource utilization product) can be used as the oil fuel product of high value and sells.
The concrete steps that the present invention handles oily sludge are as follows:
(1) oily sludge thermal desorption: oily sludge carries out thermal desorption, the solid product of generation at anaerobic, 500 ℃～550 ℃ 30min～45min of the following residence time of condition---and solid residue is discharged system.
(2) oil content catalyse pyrolysis: the oil content that steams is carried out catalyse pyrolysis, and pyrolytical condition is: 450 ℃～550 ℃ of anaerobic, temperature, catalyzer are a kind of solid waste based on silicoaluminate, and reaction contact time is 1s～10s.
(3) condensation and oily water separation: the gas that catalyse pyrolysis produces obtains pyrolysis liquid and combustible gas after condensation.Pyrolysis liquid is oil-water mixture, obtains the higher refiltered oil of quality after oily water separation.Contain a spot of water-soluble mineral oil in the isolated water, enter sewage work and handle.
(4) combustible gas utilization and gas cleaning: the combustible gas calorific value height that catalyse pyrolysis produces, can be used as the thermal source of thermal desorption and catalyse pyrolysis, enter atmosphere after the gas cleaning processing that combustible gas burning back produces.
Through this technology, the oily sludge thermal desorption is effectively separating oil and silt particle not only, realizes the innoxious of greasy filth processing; And catalyse pyrolysis produces combustible gas and realizes utilizing in internal system again, obtains the refiltered oil of high added value simultaneously, and aggregate resourceization is utilized the level height, and process economy is good.
Compared with prior art, the present invention's method of handling oily sludge has following beneficial effect:
(1) oily sludge method provided by the present invention is carried out thermal desorption to greasy filth earlier, again the oil content that steams is carried out catalyse pyrolysis, both guarantee effectively the separating of oil and silt particle in the greasy filth, can obtain costly refiltered oil again, realized resource utilization, the innoxious and minimizing of oily sludge;
(2) method of the present invention has obviously promoted the quality of refiltered oil, has improved the economy of handling;
(3) treatment process of the present invention as system's fuel of heat supply, has realized that save energy is recycled in the inside of system capacity with product-combustible gas;
(4) after the inventive method was handled, the oil content in the oily sludge was removed through thermal desorption, and bottoms product reaches the harmless treatment requirement;
(5) this treatment process is to carry out SO under oxygen free condition
x, NO
xLow with HCl pollutent generation, the lifting capacity that follow-up flue gas is handled is low, causes that the possibility of secondary pollution is little, belongs to environmentally friendly technology.
To sum up, the present invention adopts thermal desorption and the treatment process of catalyse pyrolysis two-stage to oily sludge, not only brought into play thermal desorption handle recyclable resource, adaptability strong, handle advantage completely, and solved reclaim the oil content quality low, be worth low problem, thereby reduced oily sludge treatment process cost, improved the economy of handling.This method is a kind ofly can realize resource and energy recovery utilization, the oily sludge resource treatment technique that is worthy to be popularized simultaneously.
