Vapour flows back to machine oil after bottom case is assembled inside engine and re-uses, and steam flow to engine and rekindles, prevent directly into
Enter atmosphere, cause atmosphere pollution, gs-oil separator is broadly divided into two kinds at present, labyrinthine separator and spiral vortex type separator.
And the common oil return baffle majority of labyrinthine separator is the structure of surfacing at present, can only play letter to mist of oil
Single barrier effect, separative efficiency are general.
Application No. is 201410703045.5 domestic patents of invention to disclose a kind of gs-oil separator, including is mounted on gas
Shell, setting on the cover of door room in the intracorporal S-shaped mixed gas passage of shell, setting in the intracorporal labyrinth structure of shell and cyclone structure,
Be characterized in that: the gaseous mixture entrance of the mixed-gas channel is located at the bottom of shell one end, and gaseous mixture entrance is equipped with
Block machine structure, for labyrinth structure between gaseous mixture entrance and mixed gas passage, cyclone structure is located at the end of mixed gas passage,
Mixed gas passage bottom and cyclone structure bottom are equipped with oil return control valve, the exhaust end of cyclone structure be respectively equipped with check valve and
Pcv valve.Block machine structure is equipped in this structure, this block machine body structure surface is smooth, simple barrier effect can only be played to mist of oil, point
It is general from efficiency, and this structure is complicated, easily cause failure, and higher cost, be unfavorable for for enterprise save cost.
Application No. is 201310474199.7 domestic patents of invention to disclose a kind of gs-oil separator, including is tightly connected
It is equipped on the connecting end surface of oil separator case on crankcase, oil separator case and crankcase and oil droplet is kept off into Hui Qu
Gas mixture is formed in the oil baffle of axle box, the edge of oil baffle and the connecting end surface of oil separator case between to enter
Channel, oil separator case include integrally formed Oil-gas Separation section and the fillter section for tilting upward setting, Oil-gas Separation section
Bottom surface be gradually obliquely installed upwards outward from the connecting portion of crankcase, the inner cavity of Oil-gas Separation section is filter chamber, mistake
The inner wall of filter chamber be equipped with to filter chamber convexity into and drive gas mixture in filter chamber at least one piece of curve negotiating every
Plate, fillter section are provided with filter core, and the up extension end portion of fillter section is equipped with upper capping, exhaust pipe is housed in upper capping.It is set in this structure
There is block machine structure, this block machine body structure surface is smooth, and Oil-gas Separation rate is low.
Application No. is 201510514931.8 domestic patents of invention to disclose a kind of Oil-gas Separation tooling, plane oil return gear
Plate is evenly distributed in the vertical inner wall of the external shell two sides in a manner of cross-distribution, the plane oil return baffle
One end is fixedly connected with the vertical inner wall of the external shell；Mist of oil enters Oil-gas Separation from air inlet after engine discharge
Tooling moves ahead according to the maze path being made of plane oil return baffle, and during traveling, mist of oil impinges upon plane oil return gear
On plate, oil droplet is gradually accumulated, under gravity, oil droplet is deposited on tube wall and assembles in reflux line, flows back to oil
Bottom case.
Mist of oil impinges upon on plane oil return baffle, gradually accumulates oil droplet, and plane shuttering panels and mist of oil contact area are small, collect
Oil droplet ability is poor.
Utility model content
In view of the deficiency of the prior art, it is simple to provide a kind of structure for the utility model, improves mist of oil and oil return is kept off
Plate contact area improves the gas and oil separating plant with oil return apparatus of oil gas separation.
Technical solution adopted in the utility model is:
A kind of gas and oil separating plant with oil return apparatus, including external shell, oil return baffle, inside the external shell
Equipped with Oil-gas Separation chamber, the external shell upper end is provided with gas vent and connects exhaust pipe, and the external shell lower end is opened
Have air inlet and connect reflux line, the oil return baffle at least there are two, the oil return baffle is equal in a manner of cross-distribution
Even is distributed in the vertical inner wall of the external shell two sides, and one end of the oil return baffle is vertical with the external shell
Inner wall is fixedly connected, between the other side vertical inner wall of the other end of oil return baffle and the external shell there are cross gas channel,
The oil return baffle indention (corrugated type)；Planar ends with vertical inner wall fixed connection end, zigzag oil return baffle it is convex
It is stupefied parallel with horizontal plane；Oil return baffle is welded by 8-12 block trapezoidal plate, and adjacent trapezoidal plate angle is 20-30 degree；With
The trapezoidal plate surface area that vertical inner wall is connected is greater than coupled trapezoidal plate surface area；To be connected with vertical inner wall
The surface area of one piece of trapezoidal plate is one piece of largest surface area in all trapezoidal plates, and the surface area of trapezoidal plate is sequentially reduced；Up and down
The cross-sectional area for the ventilation cavity that two adjacent oil return baffles are constituted is cross-section.
