In view of this, the present invention provides a horizontal oil-gas separation device for an engine test stand, and fig. 1 to 7 show a specific embodiment of the horizontal oil-gas separation device for an engine test stand according to the present invention.
Referring to fig. 1 to 2, the horizontal oil-gas separation device of the engine test bench provided by the present invention is used for oil-gas separation of a mixed gas exhausted from an exhaust pipeline of the engine test bench. The horizontal oil-gas separation device of the engine test bench comprises a separation tank body 1, a centrifugal assembly 2 and a turbulence assembly 3, wherein the separation tank body 1 is provided with a gas inlet 11 and a gas outlet 12 which are arranged at intervals along the transverse direction, the gas inlet 11 of the separation tank body 1 is used for being connected with a gas outlet of the engine test bench, and the separation tank body 1 comprises a first cavity 14 and a second cavity 15 which are sequentially communicated along the gas flow direction; the centrifugal assembly 2 is arranged in the first chamber 14 and is used for centrifugally filtering the mixed gas entering the first chamber 14; the turbulence component 3 is arranged in the second chamber 15 and is used for colliding and filtering the mixed gas entering the second chamber 15.
In the technical scheme provided by the invention, the air inlet 11 and the air outlet 12 which are transversely arranged are more suitable for a horizontal exhaust pipeline of an engine test bed, and the space occupation of the separation tank body 1 is reduced; the centrifugal assembly 2 throws the oil out of the inner cavity wall of the first chamber 14, so that the oil flows and is accumulated along the inner cavity wall of the first chamber 14 towards the bottom, and the oil is easier to collect; the turbulent flow component 3 further adsorbs residual oil in the gas through collision gas, and oil-gas separation is facilitated to be completely carried out.
The design does not limit the concrete representation form of the separation tank body 1, and in different embodiments, the cross-sectional shape of the separation tank body 1 can be circular, oval, polygonal or other special shapes; however, for the sake of understanding, in the present embodiment, the separation tank 1 is uniformly provided in a cylindrical shape and has a circular cross-sectional shape, and the central axis direction of the separation tank 1 corresponds to the horizontal direction and the radial direction of the separation tank 1 corresponds to the vertical direction.
It is understood that the separation tank 1 has opposite ends in the transverse direction, on which the air inlet 11 and the air outlet 12 are respectively provided; the inner cavity of the separation tank 1 is divided into the first chamber 14 and the second chamber 15 by a partition plate, and the partition plate may be provided with one or more communication ports, so that the mixed gas flows along the airflow direction entering the first chamber 14 from the gas inlet 11, flowing to the second chamber 15 through the communication ports, and then discharging from the gas outlet 12. Compared with the technical scheme that the air inlet 11 and the air outlet 12 are arranged in the vertical direction, the separation tank body 1 in the embodiment can be suitable for butt joint with the horizontal exhaust pipe of the engine test bed, and additional connecting pipelines are avoided, so that the whole experimental system is compact in structure.
Because the first chamber 14 is arranged closer to the gas inlet 11 of the separation tank body 1, the oil content of the mixed gas entering the first chamber 14 is higher; by providing the centrifugal assembly 2 in the first chamber 14, the oil in the gas mixture is more easily centrifugally thrown out to the inner cavity wall of the first chamber 14, flows along the inner cavity wall of the first chamber 14, and finally collects at the bottom of the separation tank 1, based on the fact that the oil has heavier mass than the gas and the centrifugal force is proportional to the mass. Then, the mixed gas entering the second chamber 15 after the action of the centrifugal assembly 2 may still contain part of the oil; through set up in the second cavity 15 vortex subassembly 3, vortex subassembly 3 is right gas mixture carries out relative collision for remaining fluid in the gas mixture is attached to vortex subassembly 3 is last, after the accumulation to certain quality, flows equally and assembles the bottom of the knockout drum body 1.

Further, in order to accelerate the oil discharge of the separation tank 1, in this embodiment, the bottom wall of the separation tank 1 is inclined downward gradually in the direction close to the oil outlet 13, so that a guide surface can be formed at the bottom of the separation tank 1, and the guide surface guides the oil collected at the bottom of the separation tank 1 to the oil outlet 13 uniformly, which is favorable for the oil to be discharged quickly and completely.
Further, in the present embodiment, referring to fig. 1, fig. 2 and fig. 7, the horizontal oil-gas separation device of the engine test stand further includes an oil storage assembly 4, where the oil storage assembly 4 includes an oil storage tank 41 and an oil level indicator 42, where the oil storage tank 41 has an oil inlet pipe 411, and the oil inlet pipe 411 of the oil storage tank 41 is detachably connected to the oil outlet 13 of the separation tank 1; the oil level indicator 42 is provided in the oil reservoir 41 to indicate the amount of oil in the oil reservoir 41.

So set up for the knockout drum body 1 is big in the middle of being said, the little spindle shape in both ends. Since the flow area is inversely related to the flow rate when the flow rate is constant, when the separation tank body 1 is arranged in a spindle shape, after the mixed gas enters the inner cavity of the separation tank body 1 from the gas inlet 11 at a higher speed, the flow speed of the mixed gas is reduced under the influence of the increase of the flow area, so that the mixed gas has enough time to stay in the first chamber 14 and the second chamber 15 for sufficient filtration; the filtered gas is influenced by the reduction of the flow area and is discharged from the gas outlet 12 at a high flow rate.
Referring to fig. 1 to 3, in the present embodiment, the centrifugal assembly 2 includes a rotating shaft 21 and a rotating blade 22, wherein the rotating shaft 21 is rotatably installed in the first chamber 14 along a transverse axis; the rotating blades 22 are convexly arranged on the rotating shaft 21, a plurality of rotating blades are arranged at intervals along the axis direction of the rotating shaft 21, and the rotating blades 22 are used for centrifugally throwing oil in the mixed gas out when being driven by the rotating shaft 21 to rotate. It will be appreciated that the rotary shaft 21 may be directly rotated by manual operation of the operator, but in view of reducing the dependence on manual operation and the requirement for rotational speed and rotational time, the rotary shaft 21 may alternatively be driven by a drive member, such as an electric motor, having a rotary output shaft drivingly connected to the rotary shaft 21. The separation tank body 1 is cylindrical and has a circular cross-sectional shape, so that the rotating shaft 21 can be collinear with the central axis of the separation tank body 1, and the rotating radius of the rotating blade 22 can be selected to be equal to or slightly smaller than the radius of the separation tank body 1, so that an action area as large as possible can be formed during rotation, more mixed gas can be centrifugally filtered, and the separation efficiency can be improved.
