The invention provides a cyclone-floatation integrated oil removal device which comprises a floatation tank, wherein the floatation tank is a vertical pressure vessel; the vertical pressure vessel is connected with an external tangential inlet; the other end of the tangential inlet is connected with an external microbubble generator; the microbubble generator is connected with a gas source inlet and an oily sewage inlet; the top end of the vertical pressure vessel is provided with a gas outlet and an oil outlet; the outside of the top end of the vertical pressure vessel is also provided with a gas reflux pipeline; the other end of the gas reflux pipeline is connected into the side wall of the pressure vessel; the inlet of the gas reflux pipeline is provided with a gas-liquid mixing pump; a sewage outlet on the bottom end of the pressure vessel is divided into two pipelines; and one pipeline is externally connected with the gas-solution mixing pump. When being used for treating oilfield produced water, the treatment device has the advantages of obviously higher oil removal efficiency and small occupied area of equipment.
Description
Technical field
The invention belongs to oil field produced water treatment field, particularly relate to the oily water separation process of recovered water.
Background technology
The process of oil field mining liquid is the major issue during oil-gas field development is produced always, existing treating method is by being then separated the object realizing oily water separation to dosing in recovered water, conventional separation method is that centrifugal point or air supporting realize, two kinds of distributions can not use together, there is the problem that oil removal efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of cyclone air-flotation integrated apparatus that centrifugal and air supporting can be integrated.
The present invention is achieved by the following technical programs: a kind of cyclone air-flotation integrated apparatus, comprise air flotation tank, described air flotation tank is vertical pressure vessel, described vertical pressure vessel is circumscribed with tangential inlet, the external microbubble generator of the described tangential inlet the other end, described microbubble generator is connected to air source inlet and oily(waste)water entrance; Described vertical pressure vessel top is provided with venting port and oil outlet, described vertical pressure vessel tip exterior is also provided with gas return line, the described gas return line the other end accesses described pressure vessel sidewall, and described gas return line ingress is provided with gas-liquid mixing pump; Described pressurized vessel bottom sewage outlet is divided into two pipelines, an external described gas-liquid mixing pump of pipeline.
Described tangential inlet is positioned at more than in the middle part of vertical pressure vessel.
Described gas return line accesses described pressure vessel sidewall bottom.
Low-shear pump is provided with between described oily(waste)water entrance and described microbubble generator.
Described gas-liquid mixed pump discharge is provided with under meter.
Preferably, described microbubble generator is tubular type microbubble generator.
The present invention has following beneficial effect:
Cyclonic separation and dissolved air flotation are integrated, reach 1 eddy flow+2 pneumatically supported treatment effects, processing efficiency significantly improves, and floor space is compared to single eddy flow or airfloat equipment, and area enlarges markedly.
Accompanying drawing explanation
Below in conjunction with specific embodiment, the present invention will be further described.
Fig. 1 is the schematic diagram of cyclone air-flotation integrated apparatus provided by the invention.
In figure: 1. microbubble generator, 2. low-shear pump, 3. tangential inlet, 4. gas-liquid mixing pump, 5,6., 7,8,9,10,11,12 be respectively valve.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is described further.
Embodiment: the processing technological flow of cyclone air-flotation integrated apparatus of the present invention is as follows: first oily(waste)water enters tubular type microbubble generator 1 by valve 5 through the effect of low-shear pump 2, simultaneously source of the gas entered valve 6 and also entered tubular type microbubble generator 1, micro bubble is produced in oily(waste)water, after the disperse phase oil particles collision occurred to a certain degree in micro bubble and oily(waste)water adheres to, vertical pressure vessel is entered from the tangential inlet 3 on top, in container, the disengaging zone of middle and upper part produces weak eddy flow, weak eddy flow makes the oil phase of lightweight and micro bubble migrate to pressurized vessel center on the one hand, also promote that strengthening collision therebetween adheres on the other hand, then there is " an air supporting effect ", the oil particles floating to liquid level can be discharged from pressurized vessel top depended on pressure, also can take gravity drainage, and the oil discharge outlet controlled from valve 12 is discharged, and valve 11 controls exhaust outlet, water after process is discharged from pressure vessel bottom sewage outlet, external two pipelines of sewage outlet, control respectively by valve 9 and 10, the bilge discharge pipe line that valve 9 controls enters gas-liquid mixing pump 4, by the water backflow after partially disposed, utilize the pipeline controlled by valve 7 simultaneously, gas-liquid mixing pump 4 extracts the gas of pressurized vessel headspace, again produce a large amount of micro bubbles, the pipeline controlled by valve 8 with the recirculation water of micro bubble is entered from pressure vessel bottom, the under meter exported by being connected on gas-liquid mixing pump 4 controls the amount of recirculation water, then in pressurized vessel, there is " secondary air supporting effect ".Whole treating processes is equivalent to oily(waste)water and has carried out 1 cyclonic separation and 2 dissolved air flotations.
cyclone air-flotation integrated apparatus described in the embodiment of the present invention by eddy flow and air supporting within one device integrated, be compared to the equipment of existing employing single method process, its plant area area does not have remarkable increase, and oil removal efficiency is improved.
Above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
