Description
Technical field
The present invention relates to a kind of hot gas floating deoiler for removing oil from oil-contained sewage, belong to technical field of petrochemical industry.
Background technique
In the petrochemical industry of oil field, many links in process flow can all generate oily waste water, in oil recovery factory
Crude oil, petrochemical industry oil refining process, product oil storage transport and the other industry generation of the pumping unit extraction operated daily contain
Oily waste water is machined in the waste water of the coolant liquid used, Rolling Steel in Steel Works water and agricultural and sideline food processing etc. all containing a large amount of
Oil.It discharges it into natural environment and the ecosystem and natural environment can be caused seriously when waste water does not carry out water-oil separating
It influences.As mixed liquor flow to generated in lake can oil slick, water surface generate it is a kind of hinder air reaeration oil film after, every
The source of oxygen absolutely in water body, so that the planktonic organism and fish in water can not survive.Oily waste water is discharged into municipal drainage net
Network can all impact drainage equipment and municipal sewage plant, so must be pocessed to oily waste water, reach country
It could be discharged after water quality discharge standard.
Waste water quality situation becomes more complicated at present, and the method for the processing waste water according to actual conditions is different, by big
The test and research of amount have accumulated state in some common waste water.(1) free state.This oil liquid floats rapidly when stopping.
(2) oil liquid of mechanical dispersion.This oil liquid diameter is measured with micron, can be electrolysed.(3) oil liquid of dissolved state.This oil
Liquid is very small, and conventional method can not separate this oil liquid.(4) it is attached to the grease on surface.Contain in waste water
The grease of solid matter surface absorption.Currently, wastewater treatment is mainly with the chemistry side of the physical method of Gravity Separation, addition medicament
The methods of method and biological decomposition.But in actual process.Sewage composition is more and more harsher, also constantly there is new separation side
Method.
Recent years, domestic and international scientific research personnel carry out a large number of experiments to directly affecting separation equipment flow behavior and grease point
Interior arrangement from characteristic is researched and developed.It is emerged on the components such as inlet device, oil liquid distribution, coalescence material and collection device
Many new constructions.For the form and tilt angle of the feed liquor distribution building of container, the GregoryGmong in the U.S. is deeply
Research, and has obtained relevant test result, and in a variety of tilt angles, when tilt angle is 45 °, liquid flows when installation
Extremely steady, liquid flow range is suitable with container inner width in this case, and the sky at vessel head is utilized well
Between, so that the effective rate of utilization of the water-oil separating of device is greatly improved.The dress that U.S. GregoryGmong is researched and developed
Setting structure is: being plate above, here is that the structure of corrugated plating is laminated, board group slant setting, and the olesome that oil slick rises is poly-
Collection along transverse slat planar movement and falls off on the crest location of corrugated plating, and the silt sand of sedimentation reaches upper panel and slides, effectively
It avoids the defect-in conventional corrugation plate structure and is easy precipitated silt particle obstruction dispersion liquid hole.
This field at home, Lu Yaojun et al. have carried out experimental study to the inlet location component of container, experiment have been ground
The board-like entrance structure part of the blocking selected on the basis of studying carefully, dish-style entrance structure part, centrifugal inlet device, the box entrance dress in upper hole
It sets, the simulation test that five kinds of resulting structures such as the box inlet device of lower opening carry out.Advanced velocity measuring technique (particle is used in test
Image), it is different according to coverage of the container inner structure to container flow field, comprehensive simulated experiment is carried out, it is final right
Than analysis of experiments the results show that the box inlet part of lower opening not only has preferable mobility, pre-separation dress also with higher
The effect set.It compares better than dish-shaped entrance member and baffle-type entrance structure part, centrifugal inlet device, pre-separation function and effect
It preferably, is a kind of combination that existing flow behavior also has preferable pre-separate device to act on.Structure is dispersed to container internal liquid
Part, coalescence material and fluid collection device are selected by experiment, are orifice plate type cloth liquid respectively by testing the result obtained
In three kinds of part, grid type cloth apparatus and grating type filler cloth liquid part cloth liquid knot parts, comparative test is obtained: in Gravity separate equipment
Arrival end use cloth liquid structure appropriate, to improve equipment flow behavior, reinforce stalling characteristic all have very much application, wherein with
The overall performance of dumped packing formula cloth liquid part is optimal, in addition, the introducing of liquid distributor reduces itself and wants to entrance structure part
It asks, is become a reality using efficient entrance structure part pre-separation.
Summary of the invention
Present invention mainly solves the technical issues of: the oil-water separation having for existing oil expeller is poor, sewage discharge
The high problem of oil content, the present invention provides a kind of hot gas floating deoiler for removing oil from oil-contained sewage.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention:
A kind of hot gas floating deoiler for removing oil from oil-contained sewage, including oil groove, separating tank and sink, the oil groove are arranged the bottom of at
Seat left side, oil groove right side connect separating tank, are connected between oil groove and separating tank by contaminated-oil pipeline, the separation trench bottom
It is provided with air-floating apparatus, is connected on the left of air-floating apparatus with blower, blower and air-floating apparatus junction are provided with electric heater unit,
It is provided with greasy dirt water inlet on the right side of air-floating apparatus, greasy dirt water inlet is connected with the greasy dirt waterpipe of chassis interior, and separating tank is right
Side is sink, and drainage pipeline is provided between sink and separating tank.
A kind of application method of hot gas floating deoiler for removing oil from oil-contained sewage is: greasy dirt waterpipe is connected with discharge of wastewater pipeline
It connecing, oily water enters in separating tank through greasy dirt water inlet, and then blower works, to air blast inside air-floating apparatus, while electric heating
Device heats gas, and the gas after heating is entered in separating tank in a manner of minute bubbles through air-floating apparatus, micro-bubble
The oil droplet being blended in oily water is driven to move upwards when rising in oily water, oil droplet is brought to the upper surface of oily water, together
