Abstract
The utility model relates to a preseparating hydroclone for combination oil-field production liquid, which is novel water treating equipment. A plurality of preseparating hydroclones with monomer structures for combination oil-field production liquid are assembled and fixed in a casing of a pressure vessel according to the definite proposal, and some unique designs are adopted on the interior structure of the pressure vessel to increase the treating capacity of the hydroclone and improve the separating effect of the hydroclone. The preseparating hydroclone for combination oil-field production liquid has the advantages of high efficiency, energy saving, no moving component, easy operation, easy maintenance, etc. the application of the preseparating hydroclone for combination oil-field production liquid can simplify the existing technological process and technological equipment.
Description
The utility model relates to oil-water separation technology, specifically is used for the hydrocyclone of oil field mining liquid pre-separation.
At present the comparatively desirable equipment that oil field mining liquid is carried out pre-separation is the oil field mining liquid pre-separation hydrocyclone of monomer structure, and the patent No. is ZL96210084.6.Its separation principle is to utilize two kinds of immiscible liquid density of medium poor, makes liquid produce centrifugation.Its weak point is that treating capacity is little, has only 100～200m
3About/d; Because its treating capacity is little, the influence of the fluctuation that is stressed is bigger simultaneously, thereby separating effect also is subjected to certain influence.Increase along with the field produces scale, the hydrocyclone of monomer-type can not meet the needs of production, if improve treating capacity by increasing its full diameter merely, the overall length of hydrocyclone is strengthened thereupon, separative efficiency will reduce significantly simultaneously.
The purpose of this utility model provides the combined type oil field mining liquid pre-separation that a kind for the treatment of capacity is big, treatment effect is stable hydrocyclone exactly for overcoming above-mentioned deficiency.
For reaching above purpose, the technical solution adopted in the utility model is that the oil field mining liquid pre-separation hydrocyclone with many monomer structures makes up, is fixed on a vessel shell inside by certain scheme, adopts some unique design to improve the pre-separation effect of hydrocyclone simultaneously on container inner structure.The utility model combined type oil field mining liquid pre-separation hydrocyclone comprises three cavitys, i.e. in the middle of entrance cavity, underflow chamber and spill cavity, entrance cavity are positioned at.Separate with dividing plate between each cavity, and have several holes at two corresponding positions of dividing plate, so as bleed off pipe and underflow pipe to the oil field mining liquid pre-separation hydrocyclone that is installed in some monomer structures in the entrance cavity to support, fixing, make the overflow mouth of pipe and the underflow mouth of pipe point to spill cavity and underflow chamber respectively, other two cavitys are many greatly relatively for entrance cavity, promptly adopt big as far as possible entrance cavity length under the prerequisite that does not strengthen monomer hydrocyclone entire length; In the entrance and the inner close monomer hydrocyclone inlet side design of entrance cavity that end facing to entrance cavity the flow-stopping plate assembly is arranged in addition, make oil-water mixed liquid earlier through the flow-stopping plate assembly, in entrance cavity, make wherein oil carry out to a certain degree coalescent and annex, and a sedimentation takes place.
The combined type hydrocyclone that the utility model provides compared with prior art has the following advantages: at first, owing to adopt the parallel connection of many monomer hydrocyclones on the structure, improved treating capacity greatly, and, make treatment effect more stable along with the increase for the treatment of capacity can reduce the degree of fluctuation of pressure effectively; In addition, the utility model shell adopts airtight pot type structure, adopts big entrance cavity design, and be provided with flow-stopping plate in the entrance of entrance cavity, it is coalescent fully in entrance cavity to make oil in the liquid to enter before the cyclone like this, annexs and sedimentation, helps the raising of separative efficiency.The utility model is a kind of desirable oil field mining liquid treatment facility, can replace the separation equipment of present routine fully, and its successful Application will greatly be simplified existing processes flow process and process equipment, produce huge economic benefit and social benefit.The do not dissolve each other separation of medium of the two-phase that this equipment also can be applicable to industries such as chemical industry, metallurgy, printing and dyeing, food.
Fig. 1 is the structural representation of combined type oil field mining liquid pre-separation hydrocyclone;
Fig. 2 is the A-A sectional drawing of combined type oil field mining liquid pre-separation hydrocyclone.
Introduce the structure of the present utility model and the course of work in detail below in conjunction with accompanying drawing.
The utility model combined type oil field mining liquid pre-separation hydrocyclone, be that oil field mining liquid pre-separation hydrocyclone with many monomer structures makes up by certain scheme, be fixed on a vessel shell inside, pressure vessel inside is divided into three cavitys by two dividing plates 2, it is entrance cavity 6, underflow chamber 7 and spill cavity 1, in the middle of entrance cavity 6 is positioned at, and have several holes at two corresponding positions of dividing plate, so that bleed off pipe 8 and underflow pipe 10 to the oil field mining liquid pre-separation hydrocyclone 3 that is installed in some monomer structures in the entrance cavity 6 support, fixing, make the overflow mouth of pipe and pipe underflow opening point to spill cavity 1 and underflow chamber 7 respectively, entrance cavity 6 relative other two cavitys are big as far as possible, in addition, in the entrance that faces entrance cavity 6 and the inner tangential inlet 9 one sides design of entrance cavity 6 near monomer hydrocyclones 3 flow-stopping plate assembly 4 is arranged.
During work, oil-water mixture is through coming the liquid pipeline from 5 entrance cavities 6 that enter the utility model combined type oil field mining liquid pre-separation hydrocyclone that enter the mouth, through the flow-stopping plate assembly 4 that is welded by two boards, carry out the coalescent of oil droplet and merger, and through after of short duration sedimentation and stablizing, tangential inlet 9 through each monomer hydrocyclone 3 enters monomer hydrocyclone 3, carries out the pre-separation of oil-water two-phase therein.Separate back bleed off pipe 8 discharge liquid and enter spill cavity 1, underflow pipe 10 is discharged liquid and is entered underflow chamber 7, enters the subsequent technique flow process respectively.
