Description
Technical field
The present invention relates to petroleum refining and separation technology field, more particularly to one kind obtaining pitch and for building from oil-sand
Husky system.
Background technology
Oil-sand is a kind of unconventional energy resource risen in recent years, because it contains bitumen therefore is also designated as pitch
Sand.Oil-sand is mostly black or grey black, is a kind of mixture by material compositions such as sand grains, pitch, clay particles, mean containing
The sedimentary rock of pitch or other mink cell focuses.World economy to energy demand be continuously increased and the continuous consumption of conventional oil resource
Non-conventional oil resource is set to receive more and more attention；In addition International Petroleum Price is hovered in a high position for a long time, oil-sand will be in future
It will be occupied an important position in energy resource structure.China's oil-sand resource is abundant, and oil-sand geological resources are 59.7 hundred million tons, mining resources
Amount is 22.58 hundred million tons.China's oil-sand is widely distributed, oil content is medium, oily preferable, and exploration prospect is very considerable.Have in China
For a little area oil-sand oil contents 12% or more, oil product is preferable, and in-depth study, rational development and utilization are carried out to oil-sand resource,
There is important strategic importance to Chinese energy safety.
There are two types of methods for oil-sand exploitation：For the oil-sand mine that underground is buried, typically to underground inject steam or hot-air,
Even solvent makes oil-sand viscous crude reduce viscosity, have mobility, can be separated from gravel (solid mineral grain), then use
It is pumped to ground, this extracts viscous crude technique on the spot for the underground of oil-sand.Oil-sand mine close to earth's surface be typically have an opencast mining of it is fuel-displaced
Sand, then detached viscous crude and gravel using oil-sand separation technology on ground.The main of pitch is extracted from opencast oil-sand
Method has thermokalite washing process, solvent extraction technology, thermal cracking process etc. several,（Application number 201510999342.3, Yi Zhongqin
The method of aqueous reversible solvent assisting oil-sand separation；A kind of oil-sand continuous separation technologies of 201410699046 .7 of application number；Application
A kind of number oil-sand Atmospheric vacuum destructive distillation complex solvent extraction device and methods of 201510245619 .3）.Industrial use is compared at present
Ripe is thermokalite WATER-WASHING METHOD, which first crushes oil-sand, be re-fed into heat alkali liquid and be mixed, then into mixed serum
Being passed through gas makes in pitch flotation, after collecting pitch and alkane dilution being added to reduce its viscosity, is sent to refinery and is refined
Obtain various oil products.The technical operation is simple, but has the disadvantage that and technical bottleneck：Water consumption is big, at high energy consumption, tailing
Manage that extremely difficult, environmental pollution is serious.The method for finding separation pitch in the slave oil-sand of environmental protection, economy, sustainable development is compeled
In the eyebrows and eyelashes.

A kind of groundwork process of system obtaining pitch and construction sand from oil-sand of the present invention is as follows：Oil-sand
Grain passes through screw conveyor（1）Deliver into extraction kettle（2）, come from material-compound tank（16）Proportion liquid with come from original fluid container（10）'s
Enter extraction kettle after stoste mixing（2）；Carry out flash-pot（12）Indirect steam first part enter extraction kettle（2）Chuck layer
Pass through chuck heating extraction kettle（2）, second part enters extraction kettle（2）Interior to be used to directly heat material, Part III is gone
Water heating tank（19）For the clear water in heating tube；In extraction kettle（2）Stirring action and chuck heating and steam it is direct
Under the action of heating, pitch falls off to form the suspension of pitch, Sha Heshui from oil-sand particle surface；Suspension passes through centrifugal pump
（3）It is delivered to floatation cell（5）, air passes through air pump（4）Blast floatation cell（5）Interior formation air bubble, air bubble is to suspension
In pitch carry out flotation, air bubble floats up to floatation cell（5）Top rupture release exhaust gas, exhaust gas passes through floatation cell（5）Top
The exhaust outlet in portion removes exhaust treatment system, and pitch is in floatation cell（5）Pass through floatation cell after the aggregation of top（5）Overflow port overflow go
Crude asphalt storage tank（7）；Floatation cell（5）Interior suspension is after flotation in floatation cell（5）Form husky water slurry（Still contain a small amount of
Pitch）, husky water slurry passes through centrifugal pump（6）It is delivered to three-phase centrifuge（8）Pitch, sand are obtained after three phase centrifugation detaches
And stoste（Stoste is the system containing a large amount of alkali and salt）, wherein pitch enters crude asphalt storage tank（7）, husky to enter husky water blending tank
（9）, stoste enters original fluid container（10）；Original fluid container（10）In stoste pass through centrifugal pump（11）Conveying, a part enter evaporator
（12）Evaporation forms indirect steam and concentrate, and another part enters extraction kettle（2）；In evaporator（12）The concentrate of middle formation
Pass through centrifugal pump（13）It is delivered to crystallization kettle（14）The crystal of upper layer saturated solution and bottom is formed after cooling, crystallization, precipitation,
Saturated solution is through centrifugal pump（15）It is delivered to material-compound tank（16）, crystal is from crystallization kettle（14）Bottom discharge is basic salt as solid
Useless processing；Extract kettle（2）Chuck layer in steam condensation after obtained condensed water be discharged into clean water tank（17）, from originally water system
The clear water of system is also discharged into clean water tank as supplement clear water（17）, thus clean water tank（17）In water be clear water, clear water by from
Heart pump（18）Deliver into water heating tank（19）Pass through centrifugal pump after being heated by steam（20）Convey and with from crude asphalt storage tank
（7）Crude asphalt mixing after enter pitch water washing tank（21）Pass through centrifugal pump again（22）It is delivered to two-phase centrifuge（23）Through centrifugation
Smart pitch and pitch wash water are obtained after separation；Smart pitch enters smart asphalt storage（24）, pitch wash water enters husky water blending tank（9）
With from plate and frame filter press（26）Wash water together in tank sand mix after obtain husky water mixed liquid；Cut off the tenth pipeline and
13 pipelines, husky water mixed liquid is through centrifugal pump（25）Deliver into plate and frame filter press（26）Filtering, cake layer as once wash it is husky,
Filtrate is discharged into waste water tank as waste water（27）；Centrifugal pump is cut off after the completion of band filtering（25）The pipeline at place and the 14th pipe
Line, clean water tank（17）Middle clear water passes through centrifugal pump（18）Deliver into plate and frame filter press（26）It washs, obtains to once washing sand
Husky and wash water is washed to secondary, secondary wash husky is that construction sand goes to stockyard, wash water to enter husky water blending tank（9）And with pitch wash water
It is used to once wash sand together；Waste water tank（27）In waste water through centrifugal pump（28）Conveying rear portion removes material-compound tank（16）With from
Crystallization kettle（14）Saturated solution be made into proportion liquid with alkali and surfactant together, another part enters neutralizing tank（29）With hydrochloric acid
Row outside middle water is obtained after neutralization to handle.
Compared with the prior art, the advantages of the present invention are as follows：1, pitch and construction sand are obtained simultaneously from oil-sand, improved
The level of resources utilization；2, by the comprehensive utilization of water, especially with the wash water of pitch wash water and plate-frame filtering, for husky one
It is secondary to wash sand, while stoste being recycled, the comprehensive utilization ratio of water greatly improved in above-mentioned design.
