Description
Technical field
The present invention relates to a kind of oil containing sewage filters, belong to disposing polluted water in oil technical field.
Background technology
The exploitation later stage has been arrived in major part oil field in China's at present, and moisture content is up to more than 90% in oil well produced liquid, water filling
Developing oneself becomes the major way for improving oil recovery rate and development benefit, with being continuously increased for recovery percent of reserves, oil-field flooding
Measure increasing, oil extraction-generated waste water amount also increases year by year, and how to handle these sewage is exactly a big problem.The each oil field in the whole nation due to
Water quality is different, and the sewage water treatment method taken is also different.But substantially the last one ring of sewage treatment process
Section is all by in-depth filtration, removes the sump oil in water, makes water quality reaching standard, then re-injection or discharge.Filtering is to use filter medium
（Filtrate）Continuous phase is allowed to pass through to being intercepted as the substance of dispersed phase, so as to fulfill the process of two-phase laminated flow.Filtering
Two kinds of situations：It screens out and adsorbs.For larger particle, it is impossible into the runner of filter bed, be intercepted by filter bed on surface；And
Little particle can enter the inside of filter bed with fluid, be removed inside filter bed by suction-operated.
In-depth filtration is mainly suction-operated, and filter bed can adsorb the particle more much smaller than filtrate itself.Particle is in filter bed
It is internal that there are mainly two types of motion morphologies：Migration and attachment.The filtering velocity of in-depth filtration is not generally very high, and filtrate is inside filter bed
Flow pattern be substantially laminar flow, under the action of certain power, the overall flow trend of movement tendency and filtrate occurs inclined particle
It moves, exactly migrates.The particle migrated is contacted with filtering material particle, and is adhered on the surface of filtering material particle, is exactly adhered to.
The Running-water Company of Britain has built first slow filter in the world.In terms of oil field, from 20th century the forties
It rises, water-drive oil recovery starts to develop rapidly.Some companies in the U.S. start to walk relatively early in terms of oil-containing sewage filter, no matter
It is clear water type coarse filter or clear water type fine filter, all achieves many achievements.The each oil field in China uses at present
Filter is substantially pressure filter.For example, Two-layer filter, walnut shell filter and modified fiber ball filtering
Device etc..Two-layer filter is restructured on the basis of original quartz filter.The upper strata of double-layer filter material is
Grain is bigger, and the filtrates such as anthracite or walnut shell of lightweight, lower floor is that particle is smaller, quartz sand, diamond dust, the magnet of heavy
The filtrates such as ore deposit.The arrangement of this filter bed, can be with the particle of the different-grain diameter in layered filtration filtrate, and filter effect is fine.
At present, each oil field and filter on the market are multifarious, but have certain limitation or oil removing not
Thoroughly or backwash is inconvenient or regeneration is difficult or cost is higher or energy consumption is larger, as reinjected water water quality will
A cleaning is developed in the raising asked, efficiently, of low cost and to the filter of environmental beneficial, has great realistic meaning.
Invention content
Present invention mainly solves the technical issues of：For existing filter device, there are filter efficiency is low and consume energy and larger ask
Topic, the present invention provides a kind of oil containing sewage filters.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：
A kind of oil containing sewage filter including housing, is provided with observation panel, enclosure interior is provided with gas above the housing
Buoyancy tank, air buoyancy tank are internally provided with gas pipeline, are provided with fluid pipeline on the right side of air buoyancy tank, bottom passes through pipeline and Rose Box phase
Connection is provided with backwashing water pipeline on the left of Rose Box, and Rose Box is internally provided with filter layer, respectively thick matter filter layer and thin
Matter filter layer, Rose Box bottom are provided with sludge outlet pipeline, and valve is provided on sludge outlet pipeline, is passed through on the right side of Rose Box
Pipeline connects adsorption box, and adsorption box is internally provided with adsorption layer, and bottom is provided with drainage pipeline.
A kind of application process of oil containing sewage filter is：Oily wastewater is entered into air buoyancy tank through fluid discharge of pipes,
By gas pipeline to air buoyancy tank internal discharge gas, risen in oily wastewater using gas, by larger in oily wastewater
The fluid of grain takes liquid surface to and forms oil reservoir, is extracted out oil reservoir by fluid pipeline, and it is larger to remove particle in oily wastewater
Fluid, oily wastewater enters Rose Box through pipeline after tentatively deoiling, and is filtered through thick matter filter layer and thin matter filter layer, after filtering
Sewage enters adsorption box through pipeline, and filter layer is backwashed by Backwash pipeline after filtering, and the filter residue after flushing passes through
Sludge outlet discharge of pipes, the sewage after filtering enter adsorption box, are adsorbed through adsorption layer, reach after emission request through drainage pipeline
Discharge.
Stomata is evenly arranged on the gas pipeline.
The thick matter filter layer uses walnut shell, and thin matter filter layer uses quartz sand.
The adsorption layer uses porous activated carbon.
The beneficial effects of the invention are as follows：
（1）Three kinds of modes are employed in the present invention to handle oily wastewater, are Bubble-floating Method first, using gas containing greasy dirt
Movement in water takes the fluid of larger particles to oily wastewater upper strata and forms one layer of oil film, then oil film is extracted out so as to remove
Larger fluid particle in oily wastewater, second is double medium filtration method, using the different filtering material of two layers of thickness, by oil-containing
Fluid and a part of impurity in sewage are filtered, and oily wastewater is further purified, the third is absorption method, are utilized
The absorption property of porous activated carbon adsorbs a part of chemical substance in oily wastewater, and deep level of processing is carried out to oily wastewater,
Oily wastewater is made to reach discharge standard, by being applied in combination for three kinds of methods, improves the treatment effeciency of oily wastewater, it is ensured that contain
Bilge water discharge reaches standard.
（2）Back purge system is provided in the present invention on filter device, filter layer can be filtered by back purge system
Filter residue afterwards is cleared up, and is prevented from blocking filter layer, is enabled devices to constantly stable operation, improve the filter quality of device,
Increase the service life of device.
（3）The filtering material used in Rose Box in the present invention is walnut shell and quartz sand, and material is inexpensively and filter efficiency
Height reduces the cost of oily waste water treatment, and device operation does not need to excessive energy supply, has saved the energy.
