Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Preferred embodiment one：
This preferred embodiment discloses a kind of vertical oil separator inner cylinder.As shown in Figures 2 to 4, inner cylinder 1 includes hollow tube-shape
Barrel 11, barrel 11 gradually increases from top to base diameter.Venthole is uniformly offered at the bottom margin of barrel 11
13.Venthole 13 is uniformly distributed, and number is 3 to 20 more suitable, preferably 8.
The too high separative efficiency that can reduce inner cylinder of opening area, it is too low can increase inner cylinder pressure drop, so the height of opening area
Degree needs to be designed according to service condition.Preferably, the height of venthole 13 is h, and the whole height of inner cylinder 1 is H, 0.1H≤
h≤0.5H；It is furthermore preferred that h=0.3H.
The area of venthole 13 can also have an impact to the use of oil eliminator.Specifically, the too small meeting of the area of venthole 13
Cause crushing excessive, the excessive then oil return effect of area is deteriorated.Preferably, the area sum of whole ventholes 13 is SC, barrel 11
On open up venthole 13 the gross area of opening position be SK, 0.2SK≤SC≤0.8SK.It is furthermore preferred that SC=0.6SK。
Preferred embodiment two：
This preferred embodiment discloses a kind of vertical oil separator inner cylinder, and its structure and preferred embodiment one are essentially identical.No
It is with part, as shown in Figure 5 and Figure 6, inner cylinder 1 includes the barrel 11 in frustum, upward in the tip edges of barrel 11
And extend inwardly to form top guiding device 12.
Top guiding device 12 is bigger than the slope of barrel 11, and it is more smooth to ensure that oil droplet falls.In the bottom margin of barrel 11
Place uniformly offers venthole (not shown), the shape of venthole, area equal preferred embodiments one.
Preferred embodiment three：
This preferred embodiment discloses a kind of vertical oil separator inner cylinder.As shown in Figure 7 and Figure 8, barrel 11 includes straight-tube shape
Wall main body 14, the tip edges of wall main body 14 extend upwardly and inwardly to be formed top guiding device 12, in wall main body 14
Bottom edge at downwards and it is outer in extension form bottom guiding device 15.It can be existed in the bottom guiding device 15 of umbrella shape with full weld
Region in contact on housing, to strengthen the intensity of inner cylinder.
Preferred embodiment four：
This preferred embodiment discloses a kind of vertical oil separator inner cylinder, and its structure and preferred embodiment three are essentially identical.No
It is with part：As shown in figure 9, the outer wall of top guiding device 12 is the arcwall face of evagination, oil droplet falls more smoothly, fast
Speed.
Preferred embodiment five：
This preferred embodiment discloses a kind of vertical oil separator.As shown in Figure 10 and Figure 11, the vertical oil separator includes
Housing 2, housing 2 is interior to set described inner cylinder 1 any just like preferred embodiment one to four.After such a structure of inner cylinder 1, pass through
Short transverse be gradually reduced fluid cross section of fluid channel accumulate reach increase fluid velocity purpose, by keep fluid velocity,
Effect of inertia is improved to separate oil droplet.
In order to strengthen the stability of inner cylinder, it is fixedly connected at the bottom edge of inner cylinder 1 on the inwall of housing 2.It is fixed to connect
The mode connect includes but is not limited to weld, and can meet being stably connected between the inwall of inner cylinder 1 and housing 2.
When distance change is larger between the outer wall of the inner cylinder 1 in direction and the inwall of housing 2 from top to bottom, crushing then compared with
Greatly.Maximum secting area between the outer wall of inner cylinder 1 and the inwall of housing 2 is SW(this maximum secting area SWIn being close at upper cover plate
Sectional area between 1 outer wall of cylinder and the inwall of housing 2), the maximum secting area in inner cylinder 1 is SN(maximum is equal to the inwall of housing 2 and cut
Area), preferable number range is 0.5SN≤SW≤SN, to avoid crushing excessive.That is, the top of inner cylinder 1 needs significantly to receive
Hold together.Most extreme situation is that the upper port diameter of inner cylinder 1 is almost nil, and inner cylinder 1 is in coniform.
The method for arranging of the vertical oil separator is unlimited, and preferable method for arranging is that inner cylinder 1 is set relative to the bias of housing 2
Put.As shown in figure 12, shadow region is the axial line region of inner cylinder 1 in figure, and the central point of cross mark is housing 2
Axle center.The change of method for arranging makes the oil eliminator use range wider, and the flowing velocity of fluid in the housing keeps stable,
So as to improve de-oiling efficiency of the oil eliminator to rotating fluid.
Specifically, fluid is set from the region that inlet tube 3 enters between inner cylinder 1 and housing 2 when fluid velocity is more than or equal to
When being worth (concrete numerical value can be depending on real work situation), the axial line of inner cylinder 1 is relative to the axis line location of housing 2 in remote
From the direction of fluid intake, i.e., in A areas or C areas.The fluid course of existing structure (inner cylinder 1 and housing 2 are coaxial) is become
" snail type ", speed will not steeply rise after fluid enters housing 2, avoid the occurrence of the phenomenon of fluid scouring wall.Passing through one section
Fluid can improve flow velocity because of the diminution of cross section of fluid channel product after the motion of time, keep influence of the effect of inertia to de-oiling.
When being less than setting value into fluid velocity, the axial line of inner cylinder 1 flows relative to the axis line location of housing 2 in close
The direction of body entrance, i.e., in B areas or D areas.After inlet tube 3 enters housing 2, the passage between inner cylinder 1 and housing 2 becomes more
Narrow, the speed of fluid is increased, and enhances influence of the effect of inertia to de-oiling, and de-oiling effect is more preferable.
Pay attention to, the technical principle that above are only presently preferred embodiments of the present invention and used.Those skilled in the art can manage
Solution, the invention is not restricted to specific embodiment described here, can carry out various obvious changes for a person skilled in the art
Change, readjust and substitute without departing from protection scope of the present invention.Therefore, although being entered by above example to the present invention
Go and be described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept,
Other more equivalent embodiments can also be included, and the scope of the present invention is determined by scope of the appended claims.
