Description
Technical field
The invention belongs to water-treatment technology field, refers in particular to a kind of efficiently waste water degreasing unit.
Background technology
With the development of society, oils gradually invades water body, oily waste water is formed.The amount of industrial oily waste water is big, and
And complicated component, such as the oil exploitation and processing of oil product, refinement and transport, steel rolling water, cooling and lubricating in machine-building
Liquid etc., wherein oil exploitation oily waste water is as main source.In the present age, the exploitation of oil more and more frequently, is produced
Raw oily waste water water is also bigger, if leaving the discharge of these oily waste waters, certain harm can be not only caused to environment, together
When waste a big chunk resource.Processing for oily waste water, is considered as recycling oil therein as far as possible first, so as to weight
Multiple or recycling, secondly it is also conceivable to carrying out purified treatment to waste water, then can obtain utilizable water resource.
Oiliness sewage treatment equipment and its shortcoming common at present is as follows：
(1) API types oil-water separation tank.API type oil-water separation tanks are the devices by developing.Flat flow pond, simple structure, sinks
Shallow lake effect is good, and swinging oil collecting pipe is added in order to recycle the oil of suspension.This type device is adopted in water treatment plant at present
With.Waste water in sedimentation basin the residence time for 1-3 it is small when, for oil removal efficiency up to 50~70%, this oil separator floor space is larger,
Current dead time is longer.
(2) PPI types oil-water separation tank.PPI type oil-water separation tanks are that the more tilt flat plate of installation number is based on flat flow
Water (flow) direction in oil separator, is the ramp type oil-water separation tank developed in nineteen fifty by the Shell Oil Company.It is
On the basis of parallel flow intercepter, the tilt flat plate of many quantity is installed on the inside of it along water (flow) direction, not only increases rectification
Effect, and increase effective separation area.Inclined plate spacing is 100mm, and inclination angle is 45 °.By it is separated oil in inclined plate along
The inclined-plane of inclined plate and rise, become trapped in catch in oil overhold lid afterwards, then flowed out from the overflow pipe of head cover one end, then recycled original
Oil droplet in water.This device is adapted to remove the oily waste water that oil bead diameter is more than 80 μm.
(3) CPS coalescing-plates separator.CPS coalescing-plate separators, coalescing element therein are a folded V-type plate, coalescing-plate by
Glass fibre is made, and has taphole on plate, it is allowed to coalesces oil droplet and passes perpendicularly through plate.The equipment is mainly suitable for processing oil content and exists
The sewage of 200-1000mg/L, outlet water quality is in 50mg/L or so.
(4) Performax plate coalescers.The plate coalescer of Performax is a kind of cross-flow equipment.Its agglomerated form
Be by inclined plate multiple-layer overlapped, with individual layer in contrast, the separative efficiency of coalescing-plate is greatly improved, this device
It is also less prone to block.Coalescence portion of material is usually made of different materials, such as carbon steel, polypropylene and stainless steel.Identical
Under service condition, the disposal ability of the device is more much bigger than separator before, becomes water-oil separating to miniaturization, high efficiency
The key technology of development.
(5) hydrocyclone.Water conservancy cyclone is to remove the materials such as coarse granule silt particle heavier in sewage for separating
Equipment.Sometimes it is also used for slurry dewatering.Two kinds of partial pressure formula and gravity type, frequently with circular cylinder structures or metal control
Make.Water depended on pressure or gravity are tangentially entered by structures (or metal tube) top, under the action of the centrifugal force, coarse particles material
Thrown to wall and rotate the dope downwards and formed and discharged together.With secondary after less particulate matter rotation to a certain extent
Upper bumpy flow discharge.Hydrocyclone movement-less part, simple structure；The production capacity of unit volume is larger, and it is small to account for area；Point
Stage efficiency is high (up to 80%~90%), and partition size is thin；Low cost, material consumption are few.
In conclusion these waste-oil scavengers realize oil separation to a certain extent, but deoiling effect is generally relatively low.
The content of the invention
It is an object of the invention to overcome the universal relatively low, sewage effluent pair of oil removal efficiency of existing degreasing unit generally existing
The shortcomings of environment has an impact and a kind of efficiently waste water degreasing unit developed, the device have that oil removal efficiency is high, after reduction processing
Influence of the sewage discharge to environment, the advantages that structural behaviour is good.
To achieve these goals, the technical solution adopted in the present invention is：
