A funnel-shaped oil discharge port is arranged at the lower part of the shell; a gas inlet is located at the lower end of a shell cylinder; a gas inlet pipe is tangential to the shell; a gas outlet is located at the upper end of the shell cylinder; a gas outlet pipe is vertically inserted into the shell; and the part of the gas outlet pipe inserted into the shell is provided with uniformly distributed air vents. The filter element assembly is composed of baffle plates, a stainless steel metal mesh and a composite filter element. The composite filter element is clamped and fixed in the middle by the two baffle plates and is circumferentially fixed by the stainless steel metal mesh to form the filter element assembly; the composite filter element is formed by nonwoven cloth and filter paper; the nonwoven cloth filter element is at the outer layer of the composite filter element; the filter paper filter element is at the inner layer of the composite filter element; and the filter element assembly is installed at the outer side of the gas outlet pipe. The invention has the advantages of the traditional separation mode, good separation effect, high separation efficiency and low cost and improves the oil-gas separation effect of a ventilation system of an engine crankshaft case.
Description
Technical field
The invention belongs to the automobile construction technical field, especially a kind of composite oil-gas separator.
Background technique
Deaerator is one of important spare part of motor, is the key component of oil gas separation in crankcase ventilation system.Especially along with the increasingly stringent of vehicular discharge rules, vehicular engine all begins progressively to have adopted closed crankcase ventilation system.The performance of deaerator will badly influence the engine exhaust emission index.
At present in engine crankshaft ventilation system, deaerator has a lot of structures, and that the most often adopts has three kinds of vortex type, mazy type and filer element types.Labyrinth type oil-gas separates and is comprised of several complicated dividing plates, and separation effect is lower, and the machine oil of separation waiting time in the labyrinth is longer; The Scroll-tupe deaerator is to make by the centrifugal force that the air-flow High Rotation Speed produces that in mixed gas, oil droplet is thrown on the separator wall, affected by air inflow larger; The filer element type deaerator adopts filter element filtering, and traditionally on paper filter core oil resistant water resistence is all undesirable, easily stops up, and working life is not long, and nonwovens filter element filtering efficient is low, and is not easy typing, and novel glass fiber formula filter element filtering is effective, but cost compare is high.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, proposed a kind of composite oil-gas separator.
A kind of composite oil-gas separator comprises housing and filter core assembly.Composite oil-gas separator is cylinder-like structure.Lower housing portion is provided with funnel-like unloading port, and suction port is positioned at housing cylinder lower end, and suction tude and housing are tangent, and the air outlet is positioned at housing cylinder upper end, and steam outlet pipe vertically inserts in housing, and the part that steam outlet pipe inserts housing has equally distributed vent.
Filter core assembly is comprised of dividing plate, Stainless Steel Wire Mesh and composite filter element.Two dividing plates are clipped in the middle composite filter element fixing, and are circumferentially fixed by Stainless Steel Wire Mesh, form filter core assembly; Composite filter element is made of nonwovens and filter paper, and the nonwovens filter core is outer at composite filter element, and paper filter core is at the composite filter element internal layer; Filter core assembly is arranged on the outside on steam outlet pipe.
The invention has the beneficial effects as follows: the deaerator that the present invention is designed, effectively combine two kinds of stripping technique of vortex type filer element type, this combined type separation method is efficiently separated fuel-air mixture.The eddy current that utilizes intake duct and housing to form forms vortex type and separates, then filters by combined filter element, has guaranteed the separation effect of deaerator; Adopt combined filter element, by wire netting filter core, nonwovens filter core, paper filter core multi-filtering, guaranteed the separation effect of deaerator; Combined filter element prevents that by dividing plate and wire netting typing filter core from because of oily wastewater pollution and weak distortion, having guaranteed the using effect of deaerator; Isolated oil droplet during the good recovery operation of energy at the bottom of coming together in the deaerator shell, is discharged by unloading port, prevents the oil droplet secondary pollution, improves the deaerator separation effect; Mixed gas and deaerator housing area of contact are large, are conducive to gas heat radiation, make that in mixed gas, the easier coagulating sedimentation of oil droplet gets off, and have improved the separation effect of deaerator; Can effectively reduce the separator gas flow resistance, improve the utilization efficiency of deaerator.
Description of drawings
Fig. 1 is structural drawing of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of composite oil-gas separator comprises housing 8, filter core assembly.Composite oil-gas separator is cylinder-like structure.Lower housing portion is provided with funnel-like unloading port 1, and suction port is positioned at housing cylinder lower end, and suction tude 2 is tangent with housing, and the air outlet is positioned at housing cylinder upper end, and steam outlet pipe 6 is vertical to be inserted in housing 8, and the part that steam outlet pipe 6 inserts housings 8 is provided with equally distributed vent.
Filter core assembly is comprised of upper clapboard 5, lower clapboard 3, Stainless Steel Wire Mesh 4 and composite filter element 7.Upper clapboard 5 and lower clapboard 3 are clipped in the middle composite filter element 7 fixing, and are circumferentially fixed by Stainless Steel Wire Mesh 4, form filter core assembly; Composite filter element 7 is made of nonwovens and filter paper, and the nonwovens filter core is outer at composite filter element, and paper filter core is at the composite filter element internal layer; Filter core assembly is arranged on outside steam outlet pipe.
After crank case gases tangentially enters deaerator from suction tude 2, at housing 8 guiding current downflow direction turnover 90 degree, form vortex.Be adsorbed on wall after the separated collision of large particle diameter machine oil particle in crank case gases.Mixed gas continues upwards in flow process, and gas is through Stainless Steel Wire Mesh 4, is adsorbed with the oil droplets of electric charge in a large number to settle down.Then gas goes out larger oil droplet by the nonwovens filter element filtering.At last, the filter paper filter core carries out the last degree of depth to be separated, and the gas after separation enters outlet pipe 6 through vent and discharges.Realize machine oil isolation of purified in crank case gases.
