Description

A kind of oil-gas mixer
Technical field
The utility model belongs to a kind of oil-gas mixer, more particularly to a kind of diesel engine aftertreatment regeneration system oil gas Blender.
Background technology
Can be that diesel engine installs tail gas particle catcher additional to reduce the particulate matter of diesel engine exhaust emission. Particle supplementary set device needs to be aoxidized by combustion adjuvant when regenerating, and prior art is mostly to be sprayed after being carried out by fuel injector to provide Atomized fuel is realized that difficulty is big, bad adaptability, only may be used, it is necessary to rely on Engine ECU control electric-controlled fuel injector to carry out multi-injection Suitable for high pressure co-rail system;The fuel injector research and development manufacture that multi-injection can be achieved controls grasp by international vendor, should With cost, high and application is restricted;Injection increases to the vehicle demarcation difficulty increase cycle and easily causes vehicle after fuel injector is carried out Comfortableness reduces.
The content of the invention
The shortcomings that in order to overcome prior art, the utility model provide a kind of oil-gas mixer.It is simple in construction, cost It is low, service life length.
The technical scheme in the invention for solving the technical problem is:The upper end sealing fixed weir of fuel oil seat Seat, the fixed mixing seat of lower end sealing, overflow seat, fuel oil seat and mixing seat have the inner chamber communicated respectively;It is solid on described overflow seat Determine overflow snap joint, fixation pressure overflow valve in the inner chamber of overflow seat, Pressure relief valve communicates with overflow snap joint sealing; The fixed fuel oil snap joint communicated with fuel oil seat inner chamber is sealed on described fuel oil seat;Sealed on described mixing seat it is fixed with The compressed air quick coupling and mixing snap joint that mixing seat inner chamber communicates, fuel oil seat with mix seat between sealing fix oil spout Metering device, oil spout metering device communicate with the inner chamber of the fuel oil seat, mixing seat.
The utility model has following advantages:1), do not limited by engine flat, be applicable to all delivery temperatures and meet Engine, vehicle and the system for needing progress particulate regeneration of condition;2), easily realize, it is only necessary to using engine fuel and Vehicle compressed air, it is the stable pressure of sustainable output and realization by controls such as steady pressure of system valve, return valve, hybrid channels Good atomizing effect;3), cost declines to a great extent compared with electric-controlled fuel injector, and only single branch heavy-duty diesel vehicle electric-controlled fuel injector is very One of price;4), fuel oil injection opportunity is not influenceed by engine body circulation, passes through independent Fuel Tanking Unit and interiors of products Fuel oil fluctuation of oil storage space when can engine be worked minimize;5), by independent measurable injector to combustion Oil spurts amount carries out quantitative control, and independently of engine fuel oil system, system calibrating is realized easy;6), device is all aluminium alloy Material is process, and is not corroded by fuel oil and environment, without being contacted with high-temperature gas in cylinder, service life length.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model right view.
Embodiment
As shown in figure 1, the upper end sealing fixed weir seat 2 of fuel oil seat 5, the fixed mixing seat 7 of lower end sealing, overflow seat 2, combustion Font 5 and mixing seat 7 have the inner chamber communicated respectively;Fixed weir snap joint 1 on described overflow seat 2, the inner chamber of overflow seat 2 Middle fixation pressure overflow valve 3, Pressure relief valve 3 communicate with the sealing of overflow snap joint 1;Seal and fix on described fuel oil seat 5 The fuel oil snap joint 4 communicated with the inner chamber of fuel oil seat 5;The fixed pressure communicated with mixing seat 7 inner chamber is sealed on described mixing seat 7 Contracting air snap joint 8 and mixing snap joint 12, fuel oil seat 5 seal fixed oil spout metering device 6 between seat 7 with mix, sprayed Oil measurement device 6 communicates with the inner chamber of the fuel oil seat 5, mixing seat 7.
The interior intracavitary of the mixing seat 7 is stretched into the described port of export of oil spout metering device 6 sealing, oil spout metering device 6 with There is long annular groove 10 between the inner chamber of mixing seat 7.Ensure the uniformity of mixing.
The described entrance point of mixing snap joint 12 is horn mouth 11.
Described overflow snap joint 1 is screwed with overflow seat 2 by sealing ring;Described fuel oil snap joint 4 with Fuel oil seat 5 is screwed by sealing ring;Described compressed air quick coupling 8, mixing snap joint 12 seal with mixing seat 7 It is fixed.
Fixed check valve 9 is sealed between gas circuit of the described compressed air quick coupling 8 with mixing the inner chamber of seat 7, prevents bavin Oily gaseous mixture flows backwards.
Fixation pressure sensor 14 on described fuel oil seat 5, the probe of pressure sensor 14 is in the inner chamber of the fuel oil seat 5 It is interior.The inner chamber intermediate fuel oil pressure of fuel oil seat 5 can be monitored and whether reach preset standard, and feedback control system carry out injection control or Person's fault alarm.
There are fuel oil seat fixing hole 13 and mixing seat fixing hole 15 respectively on described fuel oil seat 5 and mixing seat 7.To fix The utility model.
