Embodiment
In order to better the intent of the present invention is described, below in conjunction with accompanying drawing, content of the present invention is described further.
With reference to shown in Fig. 1-5, Fig. 1 shows a kind of cyclone type oil-gas separator, it comprises columniform whirlwind urceolus 3, be provided with columniform whirlwind inner core 4 and thin walled cylinder 6 in the inside of whirlwind urceolus 3; thin walled cylinder 6 is arranged on upper half part inside cylindrical whirlwind urceolus 3 and between whirlwind urceolus 3 and whirlwind inner core 4, make to have an appointment between the outer wall of thin walled cylinder 6 and cylindrical whirlwind urceolus 3 internal face the annular gap of 3 ~ 8 millimeters.
Be provided with oil drain out 2 in the bottom of whirlwind urceolus 3, and be provided with entrance 1 in the upper side of whirlwind urceolus 3, be also provided with oil baffle 5 in whirlwind urceolus 3 inner lower.Wherein, entrance 1 is connected with the outer wall of whirlwind urceolus 3 and gas can tangentially be entered in whirlwind urceolus 3.In addition, a pair slot 7 is symmetrically fixed with at cylindrical whirlwind urceolus 3 inner wall lower.
As in Figure 2-4, the wall of thin walled cylinder 6 has some semicircle aperture 6-1, aperture 6-1 is provided with towards the inclination tabs 6-2 of airflow direction; thin walled cylinder 6 top is provided with flange 6-3; wherein, in order to more be conducive to entering of air-flow, the inclination angle of inclination tabs 6-2 is set to 30 ~ 45 degree.As shown in Figure 2, Figure 4 shows; what thin walled cylinder 6 outer wall becomes symmetry is provided with the cutting 6-4 highly identical with thin walled cylinder 6; it matches with two group slots 7 installed symmetrical inside whirlwind urceolus 3; like this; when thin walled cylinder 6 is put into whirlwind urceolus 3 vertically, the cutting 6-4 on thin walled cylinder 6 is corresponding with the slot 7 on whirlwind urceolus 3, along with putting into of thin walled cylinder 6; cutting 6-4 will embed in slot 7 completely, thin walled cylinder 6 circumference can be stoped mobile.
In addition, as shown in Figure 3; thin walled cylinder 6 top is provided with a circle becomes an angle of 90 degrees flange 6-3 with the stack shell of thin walled cylinder 6; after whirlwind urceolus 3 put into by thin walled cylinder 6; flange 6-3 can ride over the upper edge of whirlwind urceolus 3; and then upper cover plate is tightly fixed on the top of whirlwind urceolus 3, like this prevention thin walled cylinder 6 is moved axially.The combination of cutting 6-4 and flange 6-3 will make thin walled cylinder 6 to be steadily fixed in whirlwind urceolus 3, and can not rotate with gas shock movement.In upper half part of whirlwind urceolus 3, flow field cyclonic action is comparatively strong, and the oil film of formation is thicker, therefore the height of thin walled cylinder 6 only needs the upper half part blocking whirlwind urceolus 3, need not run through in whirlwind urceolus 3 from top to bottom completely.
As shown in Figure 4, when using the deaerator in technical solution of the present invention, mixed gas is tangentially entered in deaerator by entrance 1, flow into for avoiding affecting mixed gas, thin walled cylinder 6 inside whirlwind urceolus 3 cuts away the part covering entrance 1, and therefore uncrossed tangentially direction is entered the annular space formed between whirlwind outer cylinder body 3 and whirlwind inner barrel 4 by mixed gas, rotates, can be subject to larger centrifugal force because oil droplet compares to gas, therefore motion is in the outside of radial direction.At this moment, first a part of oil droplet is thrown toward thin walled cylinder 6, and start first time separation, oil droplet sticks on thin walled cylinder 6 internal face and flows downward.Because thin walled cylinder 6 is installed as far as possible near outer cylinder body, after remaining mixed airflow arrives the thin annular space between whirlwind urceolus 3 and thin walled cylinder 6 along the passage formed between the semicircle aperture 6-1 on thin walled cylinder 6 and tabs 6-2, still there is higher kinetic energy, rotational flow will be continued, the same with traditional cyclone type oil-gas separator, oil droplet wherein clashes into whirlwind outer tube inner wall face, and converge on wall and flow downward, but unlike, its oil film formed is due to the stop of thin walled cylinder 5, can not be subject to again " scratch " that swirling eddy is strong, but directly converge into strand and flow downward, thus it is separated.And the little oil droplet of secondary that the oil droplet shock oil film seldom measured produces is also due to the stop of thin walled cylinder 6 surface thereof tabs 6-2, be difficult to flow out from oil drain out 2 along with air-flow is involved in gas phase flow field, these all will effectively improve the separation effect of whirlwind separator again.Thin walled cylinder 6 self also has the effect collecting oil droplet, it also can form very thin oil film, also have the little oil droplet of secondary of seldom amount during gas shock this layer of oil film, but equally due to the stop of inclination tabs 6-2, these little oil droplets are also difficult to be swept away by rotary gas smoothly.And it is all very little that the height that on thin walled cylinder 6, the diameter of aperture 6-1 and tabs 6-2 dig compares to whirlwind outer cylinder body, so the increase of thin walled cylinder 6 will be very little on the impact of rotational flow field uniformity.
Embodiments of the invention are only the descriptions carried out the preferred embodiment of the present invention; not design of the present invention and scope are limited; under the prerequisite not departing from design philosophy of the present invention; the various modification that in related domain, engineers and technicians make technological scheme of the present invention and improvement; protection scope of the present invention all should be fallen into; the technology contents of request protection of the present invention, all records in detail in the claims.
