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 technology
In the petrochemical industry of oil field, many links in technological process 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. and all contains largely
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 experiment and research of amount have accumulated state in some common waste water.（1）Free state.This fluid floats rapidly when stopping.
（2）The fluid of mechanical dispersion.This fluid diameter is weighed with micron, can be electrolysed.（3）The fluid of dissolved state.This oil
Liquid is very small, and conventional method can not possibly separate this fluid.（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, fluid distribution, coalescence material and collection device
Many new constructions.Form for the feed liquor distribution structure of container and angle of inclination, the GregoryGmong in the U.S. is deeply
Research, and has obtained relevant test result, and in a variety of angles of inclination, when angle of inclination 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：The above is tablet, and 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 blocking, dish-style entrance structure part, centrifugal inlet device, the box entrance dress in upper hole selected on the basis of studying carefully
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 is used in experiment（Particle
Image）, it is different to the coverage of container flow field according to container inner structure, comprehensive simulated experiment is carried out, it is final right
It is shown than analysis of experiments result, the box inlet part of lower opening not only has preferable mobility, also has higher pre-separation dress
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
Preferably, it is a kind of combination that existing flow behavior also has preferable pre-separate device to act on.Structure is disperseed 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, contrast test obtains：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 wanted to entrance structure part
It asks, is become a reality using efficient entrance structure part pre-separation.
