Description
Technical field
The utility model relates to technical field of petrochemical industry more particularly to a kind of air bearing to coalesce strong cyclone deoiling equipment.
Background technique
Inside petrochemical industry, a large amount of oily wastewater can be generated in the production processes such as exploitation, processing, refinery.This
It from Produced Liquid oily wastewater discharge to the end or re-injection during a, is carried out by a series of separators, these dresses
It sets including, three phase separator, hydrocyclone, air-floating apparatus, common filter device, film filter etc..
Hydrocyclone (Hydrocyclone, HC) be used for water treatment technology section, be a kind of oil water separator, due to compared with
Gravity Separation, sedimentation acceleration can be improved to 100 times of acceleration of gravity, therefore volume, efficiency have very big advantage.
Air bearing screening device is as a kind of separator in petrochemical industry, due to having removal compared with small size particle
Advantage is widely used.The common air bearing screening device residence time is long, and volume is big, takes up a large area, low efficiency, is applicable in model
It encloses and is very restricted, be not suitable for the occasion taken up little area, such as offshore platform, floating production ship etc..And compact cyclone gas
It is floating, become preferable air-floating apparatus.
Since hydrocyclone is preferable for processing 10um or more oil droplet effect, and not for < 10um oil droplet treatment effect
Add, and compact cyclone air-flotation (Compact Floatation Uint, CFU), wherein microbubble has 10um or less oil droplet poly-
Knot and rolling action, but swirl strength is weak eddy flow, about several times of acceleration of gravity, therefore volume is larger.
Current hydrocyclone HC, even if international state-of-the-art structure, can only also efficiently separate 10um or more partial size
Oil droplet, oil droplet effect below for 10um are bad.But its advantages are 100 times for settling acceleration as acceleration of gravity,
Disengaging time is extremely short (about < 10s), therefore volume is very compact.
Current compact cyclone air-flotation device CFU is touched smaller oil droplet using microbubble (10um to 40um) (such as < 10um)
It hits, coalescence forms that density is lighter, the bigger adherend of partial size, then is separated under cyclonic action.And what its eddy flow generated sinks
The acceleration of gravity that acceleration is several times drops, therefore equipment is reduced with respect to traditional equipment, but then compared with hydrocyclone
It is bigger.On the other hand, to further increase efficiency, the method for increasing the residence time is mainly taken, so that volume is more
(the equipment residence time is about 3min-15min) greatly.
