Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As Fig. 1, Fig. 2 and shown in Figure 3, embodiment according to gs-oil separator of the present utility model, comprise outer cylinder body 2, be arranged on the centrifugation section 1 in the outer cylinder body 2 and seal outer cylinder body 2 to form the end cap 3 of inner space, centrifugation section 1 is connected outer cylinder body 2 inboards, and is formed with independent annular housing, centrifugation section 1 also have make annular housing and extraneous inlet communicating portion and towards end cap 3 so that the export department 16 that annular housing communicates with the inner space.As shown in Figure 1, centrifugation portion 1 comprises the inner barrel 11 with outer cylinder body 2 coaxial settings, and the left shrouding 12 and right shrouding 13 that connect outer cylinder body 2 and inner barrel 11, and export department is arranged on left shrouding 12 or the right shrouding 13.Inlet portion has admission line 4, and admission line 4 is arranged on outer cylinder body 3 one sides, and makes gas mixture enter centrifugation section 1 along the center circle tangential direction of the horizontal cross-section annulus of the annular space of centrifugation section 1.The admission line 4 of arranged tangential makes the gas mixture that enters along inboard tangential the flowing of cylindrical shell, can reduce the resistance of gas flow to greatest extent, makes it obtain the good mobility energy.Gas mixture enters in the annular housing of centrifugation section 1, because annular housing is an individual cavity, only have with extraneous inlet communicating portion and towards end cap 3 so that the export department 16 that annular housing communicates with the inner space, therefore, the gas that enters can only flow out from export department 16, export department 16 is arranged on gas mixture along the end of toroidal cavity after the mobile week, because gas mixture tangentially direction flows into, even export department 16 is nearer apart from air inlet, the gas mixture that enters also can't flow out along export department 16 under effect of inertia and pressure effect, perhaps only having seldom, a part can flow out from export department 16, majority of gas and can flowing along with gas flow direction, thus, gas mixture will obtain bigger mobile stroke, can have comparatively sufficient centrifugal effect, bigger oil droplet is separated under the action of the centrifugal more fully.
As a kind of optimal way of present embodiment, centrifugation section 1 also comprises dividing plate 14, is arranged in the annular housing, is positioned at a side of inlet portion, and inlet portion and export department 16 are kept apart.Dividing plate 14 makes admission line 4 and export department 16 keep apart, and has also just got rid of fully from air inlet pipe phenomenon of directly flowing out from export department 16 of 4 gas mixtures that enter all, and the gas that enters just can be flowed out from export department 16 after annular housing flows a week.Preferably, dividing plate 14 next-door neighbour's admission lines 4 are provided with, and are positioned at the low-pressure area that gas mixture enters back formation, and export department's 16 next-door neighbour's dividing plates 14 are provided with.
As shown in Figure 1, for the centrifugal action of utilizing gas mixture to be had in annular housing is more fully separated bigger oil droplet, centrifugation section 1 also comprises hydraulic barrier 15, is arranged in the annular housing, in order to be from upstream to the flow direction that the downstream continuously changes gas mixture along annular housing.Hydraulic barrier 15 in the annular compartment of centrifugation section comprises first group of hydraulic barrier that circumferentially is provided with along external annulus and the second group of hydraulic barrier that circumferentially is provided with along internal ring wall, and each hydraulic barrier in each hydraulic barrier in first group and second group is crisscross arranged one by one.The existence of hydraulic barrier 15, make the gas mixture that flows in the annular housing in process of flowing, continuously change the flow direction, because gas is lighter, oil droplet density is bigger, under the double action of effect of inertia and centrifugal action, because stopping of hydraulic barrier 15, gas continues to move along annular housing, oil droplet then is deposited on the hydraulic barrier 15, perhaps be attached on the barrel, and form big oil droplet drippage, gas mixture all can experience the separation of an oil droplet at every turn through a hydraulic barrier 15, in the whole flow process of gas, oil droplet can be separated fully.
In order to make gas have more stable flowing, to avoid forming sinuous flow or turbulent flow, the caused fluctuation of influence owing to hydraulic barrier 15 should be less in flow process for gas, in order to make hydraulic barrier 15 both have oil droplet centrifugation preferably, flowing gas is flowed through still have stable fluidal texture and correct flow direction after the hydraulic barrier 15, in the present embodiment, hydraulic barrier 15 adopts the word of falling V structure, most advanced and sophisticated center circle setting towards the horizontal cross-section of annular housing annulus, preferably, the tip is arranged on the center circle.Because hydraulic barrier 15 is crisscross arranged one by one along internal ring wall and external annulus respectively, therefore, can make full use of centrifugal action in the gas mixture flow process, and hydraulic barrier 15 tips of V word structure are arranged on the center circle of horizontal cross-section annulus of annular housing, can guarantee that gas has flow direction conversion stably when flowing through hydraulic barrier 15, under the folding retaining of next hydraulic barrier 15, form sinuous flow after one of them hydraulic barrier 15, influence the centrifugal action of annular housing and be unlikely to make gas to be flowed through.
