Abstract

The invention discloses a closed eddy current radial gas flotation oil removal method. The method is characterized in that: oil-containing sewage in which gas is dissolved tangentially enters a closed vertical circular cylinder-shaped container to directly produce eddy current rotation or enters an eddy current component in the closed container to produce the eddy current rotation, oil gas is moved toward an inner circle through centrifugal force generated by the eddy current rotation and is gathered at the inner circle, then oil is upward floated to the top of the container by gas buoyancy and is taken out for recovery by gas from an oil receiving port on the top, and the sewage enters the next stage for treatment after the oil is removed. The radial gas flotation oil removal method has the advantages of small volume, low gas consumption and good oil-removing effect, and can be widely used for oil removal in various oil-containing sewage treatment devices.

Description

Airtight eddy current is the oil removal by air bubbling method entad
Technical field
The present invention relates to the entad deoiling method of oil removal by air bubbling method, especially oil field and refinery oily water treatment of a kind of airtight eddy current.
Background technology
The method that big jar of sedimentation, sewage lagoon sedimentation, oil removal jar, oil trap, dispersion air supporting and air-dissolving air-float are arranged at the oil removal plant of usefulness in oil field and the refinery oily water treatment, above method exists that volume is big, floor space is big, add that dose is big, working cost is high, weak effect, oil gas volatilization contaminate environment, all can not place in other water treatment device and together use.
Be head it off, China has announced the utility model patent (patent No.: 200620086735.1, patent name: air flotation turbo) though in solved the big problem of floor space, this patent still exists dosing working cost height, oil gas volatilization contaminate environment, Yi Yichi, weak effect and can not be placed in other oil-contained waste water treatment device the problem of together using and do not solve.
Summary of the invention
The objective of the invention is to provide entad oil removal by air bubbling method of a kind of airtight eddy current, to dwindle the oil removal plant volume, reduce the air supporting gas consumption, improve the oil removal by air bubbling effect, also solve dosing working cost height, oil gas volatilization contaminate environment, Yi Yichi, weak effect effectively simultaneously and can not be placed on the technical barrier that together uses in other oil-contained waste water treatment device.
For achieving the above object, technical scheme of the present invention is: give the molten gas of oily(waste)water earlier on the water inlet pipe of container tank, oily(waste)water tangent line behind the molten gas enters the interior directly generation of airtight vertical rounded cylindrical container tank eddy current rotation or enters in the interior eddy current member of encloses container jar, produce the eddy current rotation by the eddy current member, the centrifugal force that rotates generation by eddy current is with together inwardly circle migration of oil gas, oil gas is after interior circle is assembled, by the buoyancy of gas with the oil tank deck that floats, take oil out of recovery from the top receiving port by gas, sewage after the oil removing advances next stage to be handled, this airtight eddy current entad oil removal by air bubbling method both can use separately, also can be placed in other oil-contained waste water treatment device together to use.
As a further improvement on the present invention, on the barrel tangent line of airtight vertical rounded cylindrical container, be provided with water-in, oily(waste)water behind the molten gas entered directly produce the eddy current rotation in the container tank.
Further improve as of the present invention, the eddy current member is housed in the encloses container jar, molten gas oily(waste)water enters in the interior eddy current member of encloses container jar, and the eddy current member makes molten gas oily(waste)water produce the eddy current rotation in container tank.
The volume that the invention has the advantages that device is little, floor space is few, not dosing, working cost is low, the air supporting gas consumption is little, deoiling effect good, oil gas easily reclaims, receive that oily purity is highly easily utilized, the gaseous volatilization amount is little, effective to the protection of environment, for oily water treatment provides entad oil removal by air bubbling method of a kind of new eddy current.
Embodiment
Airtight eddy current of the present invention is the oil removal by air bubbling method entad, the steps include:
(1) start lift pump oily(waste)water is promoted, the water inlet pipe by container tank supplies water to container tank.
(2) after supplying water normally, the molten gas port of opening on the container tank water inlet pipe is given the molten gas of oily(waste)water.
(3) the oily(waste)water tangent line behind the molten gas enters the oily(waste)water that directly produces in the airtight vertical rounded cylindrical container tank behind eddy current rotation or the molten gas and enters in the eddy current member in the encloses container jar and produce the eddy current rotation.
(4) molten gas oily(waste)water is migrated the gentle inside circle of oil by the centrifugal force that the rotation of the eddy current in container tank produces.
(5) at the gentle buoyancy by gas of interior round accumulative oil with the oil tank deck that floats, take oil out of recovery from receiving port by gas, finish entad oil removal by air bubbling of airtight eddy current.
In the said step (1), with lift pump the oily(waste)water of handling is promoted pressurization and supply water for the encloses container jar by water inlet pipe.
In the said step (2), after water supply was normal, connection source of the gas line was opened the molten gas port molten gas in oily(waste)water on the water inlet pipe.
In the said step (3), directly produce in the tangent line water-in of oily(waste)water behind the molten gas by airtight vertical rounded cylindrical container tank enters jar in the eddy current member of eddy current rotation or the molten gas oily(waste)water water inlet pipe by the encloses container jar in entering jar, in the encloses container jar, produces eddy current by the eddy current member and rotate.
In the said step (4), molten gas oily(waste)water rotates the centrifugal force of generation with inwardly circle migration of oil gas by the eddy current in container tank, finish oil gas and water sepn.
In the said step (5), interior round accumulative oil gas is taken oil out of recovery from the tank deck receiving port by gas at the buoyancy float downward tank deck of gas, and sewage advances the next stage processing after the oil removing, finishes entad oil removal by air bubbling of airtight eddy current.
Airtight eddy current entad oil removal by air bubbling method is characterized in that: molten gas oily(waste)water tangent line enters the interior directly generation of airtight vertical rounded cylindrical container tank eddy current rotation or molten gas oily(waste)water enters generation eddy current rotation in the interior eddy current member of encloses container jar, the centrifugal force that rotates generation by the eddy current in container tank is with inwardly circle migration of oil gas, interior circle accumulative oil gas is at the buoyancy float downward tank deck of gas, take oil out of recovery from the tank deck receiving port by gas, the sewage after the oil removing advances next stage to be handled.This method have volume little, take up an area of less, few, the not dosing, effective of gas consumption, can be widely used in oil removing in the various oil-contained waste water treatment devices.
