Abstract
The invention discloses an oil-gas separator which comprises an engine oil separating tank, a gas inlet pipe, a gas exhaust pipe, and an engine oil discharging hole. A gas inlet is formed in one side of the lower portion of the engine oil separating tank. A cyclone separating tank is arranged outside the engine oil separating tank. The engine oil discharging hole is formed in the bottom of the cyclone separating tank. A collision separating tank is embedded in the cyclone separating tank in a sleeved mode. A gas inlet is formed in the upper portion of the collision separating tank. An oil separating cap is arranged at the gas inlet of the collision separating tank. An engine oil leakage hole is formed at the bottom of the collision separating tank. An exhaust pipe is arranged in the center of the bottom of the collision separating tank and is communicated with the outside. The oil-gas separator is small in size and further reduces the engine oil content of gas carry-over through double oil-gas separating modes.
Description
Technical field
The present invention relates to a kind of deaerator, especially carry out the small volume deaerator of whirlwind and the dual branch oil of collision.
Background technique
As everyone knows, in the motor of automobile, when this engine operation, the gas blowby that contains a large amount of unburned hydrocarbons can be scurried in the crankcase from the gap of piston and cylinder.As this gas blowby is discharged into the atmosphere, then can cause pollution of atmosphere.Be to reduce the pollution to atmosphere, the technical measures of taking are, utilize so-called crank box forced ventilation device to allow this gas blowby turn back to suction system and allow it burn again.Contain the mist of oil that a large amount of lubricant oil such as engine motor oil are formed by corpusculed in the gas blowby, if allow this gas blowby that contains mist of oil directly return suction system, the pipe interior of suction system will be by this oil pollution.So the technical measures of taking are, utilize deaerator from gas blowby, machine oil to be separated after, allow gas blowby return suction system again.
Such as Chinese patent: deaerator (CN 102477882 A), a kind of deaerator is provided, gas inlet tube (13) is arranged on a side of vortex type machine oil separation portion (11), gas outlet pipe (15) is arranged on opposite side.Therefore, do not allowing the gas blowby introduced from gas inlet tube (13) reverse end for end this gas blowby to be discharged outside machine oil separation portion (11) from gas outlet pipe (15) under the rotating situation.In the deaerator that comprises vortex type machine oil separation portion, prevented dispersing again of machine oil.
But above-mentioned deaerator only adopts a kind of separating measure of vortex type, and for the oil droplet inferior separating effect of variable grain size, the slight lifted of separating effect causes the deaerator volume significantly to increase.
Summary of the invention
In order to solve existing deaerator for the oil droplet inferior separating effect of variable grain size, the shortcoming that a spot of lifting of separating effect causes the deaerator volume significantly to increase, the invention provides a kind of deaerator, not only adopt dual Oil-gas Separation mode, and two kinds of gas and oil separating plants are that nested structure further dwindles the deaerator volume.
The technical solution adopted for the present invention to solve the technical problems is: a kind of deaerator, its composition comprises: the machine oil knockout drum, intake duct, outlet pipe, the machine oil tap hole, machine oil knockout drum bottom one side is provided with intake duct, machine oil knockout drum outside is provided with the cyclonic separation jar, the cyclonic separation pot bottom is provided with the machine oil tap hole, the embedded collision knockout drum that is with of cyclonic separation jar, collision knockout drum top is provided with suction port, suction port place in the collision knockout drum is provided with the oily cap of branch, collision knockout drum bottom is provided with the machine oil small opening, and collision knockout drum bottom centre is provided with an outlet pipe and and external communications.
Further described, cyclonic separation jar inner chamber is round table-like, and base diameter is greater than top diameter, and the cyclonic separation pot bottom is lower than level away from oily exhaust port near machine oil exhaust port level.
Further described, the outer contour shape of collision knockout drum is similar to cyclonic separation jar inner chamber and leave the space with cyclonic separation jar inner chamber.
Further described, dividing oily cap side is the conical surface, and suction port and conical surface top distance are the shortest, and conical surface edge is provided with arc Oil-gas Separation face.
Further described, divide the collision knockout drum bottom under the oily cap to be provided with outlet pipe, what collision knockout drum bottom also was provided with machine oil small opening and machine oil small opening is in the hollowest place, collision knockout drum bottom.
The invention has the beneficial effects as follows: volume is little, and dual Oil-gas Separation mode further reduces the machine oil content of gas blowby.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of deaerator sectional view of the present invention.
Fig. 2 is the oily cap sectional view of the branch of a kind of deaerator of the present invention.
1. cyclonic separation jars 2. collide knockout drum, 3. cyclonic separation tank top in the drawings, 4. suction port 5. collides knockout drum top, 6. minute oily cap, 7. inner chamber, 8. intake duct, 9. machine oil small opening, 10. cyclonic separation pot bottom, 11. outlet pipe, 12. collision knockout drum bottom, 13. machine oil tap holes, 14. arc Oil-gas Separation faces.
Embodiment
Below in conjunction with embodiment of accompanying drawing narration, the invention will be further described.
In the drawings, the cyclonic separation jar 1 embedded collision knockout drum 2 that is with, leave the gap between cyclonic separation jar 1 and the collision knockout drum 2,3 joints, cyclonic separation tank top are cambered surface, cyclonic separation jar 1 inner chamber 7 be shaped as round table-like and base diameter greater than top diameter, collision knockout drum 2 appearance profiles and base diameter identical with cyclonic separation jar 1 inner chamber 7 shapes is greater than top dimension.Cyclonic separation pot bottom 10 is the conical surface, and intermediate altitude is than the edge height, and cyclonic separation pot bottom 10 edges are provided with machine oil tap hole 13, and cyclonic separation pot bottom 10 centres are provided with and collide the outlet pipe 11 that knockout drum 2 is connected.Cyclonic separation pot bottom 10 sides are provided with intake duct 8 and intake duct 8 is communicated with cyclonic separation jar 1 inner chamber 7.Collision knockout drum end face is provided with suction port 4, and suction port 4 belows are provided with taper and divide oily cap 6, divide oily cap 6 bottom margins to be provided with the arc Oil-gas Separation face 14 that upwarps.12 neutral positions, collision knockout drum bottom are provided with outlet pipe 11, and 12 edges, collision knockout drum bottom are provided with machine oil small opening 9, and machine oil small opening 9 positions are lower than the relief opening position.
During use, gas blowby is introduced intake duct 8, gas blowby rises along the rotation of inner chamber 7 walls at cyclonic separation jar 1, machine oil is discharged through the machine oil exhaust port at the coalescent inflow cyclonic separation of inner chamber 7 walls pot bottom 10 under action of centrifugal force, gas blowby arrives cyclonic separation tank top 3 and enters the oily cap 6 of collision knockout drum 2 impact branches from suction port 4, machine oil flows to the edge being flocked under the effect of impact force under the oily cap of branch 6 surfaces and the drive at air-flow, when machine oil arrives the Oil-gas Separation face because Oil-gas Separation face marginal existence pressure difference, machine oil separates inflow collision knockout drum bottom surface and enters cyclonic separation jar 1 discharge deaerator through machine oil small opening 9 with gas blowby, gas blowby enters outlet pipe 11 and discharges, and the present invention guarantees that to the separation that gas blowby carries out twice different modes the volume of the higher while separator of gas blowby turbidity test is less.
