Description
Technical field
This utility model relates to a kind of dual-fuel diesel engine blender, is specifically related to the blender of a kind of LNG/ diesel dual-fuel diesel engine.
Background technology
Natural gas, at China's rich reserves, is a kind of low price, efficient, the fuel of cleaning.But what present natural gas engine was commonly used is static mixer, although its simple in construction, but there are disadvantages that, such as processing difficulties, relatively costly, charging efficiency is low, cause mixed gas mixing uneven, burn insufficient, which not only adds the discharge of atmosphere pollution, and cause the waste of resource.As disclosed in CN 204299724U " a kind of marine engine LNG/ diesel dual-fuel blender ", it includes wound packages mixer core and some blender external parts.This blender arranges 32 gas spraying perforations to realize being evenly mixed on sidewall of gas, and natural gas enters annular space by spray-hole and mixes with air.Although this blender simple in construction, with low cost, but this blender mixed effect is undesirable, causes the waste of resource.As disclosed in CN 104564431A " fuel gas mixer of a kind of dual fuel engine ", this blender is made up of spool and cylinder, spool is connected with inwall by support plate, Gas Pipe enters into inner barrel by the circular hole in the middle part of cylinder, some apertures are had on spool, combustion gas enters into spool by the Gas Pipe in the middle part of cylinder, is mixed with air by the some apertures on spool.Although this blender is simple, but mixed effect is unsatisfactory, and during life-time service, owing to the vibrations of diesel engine also can cause blender to reveal, causes potential safety hazard.
Summary of the invention
The purpose of this utility model is the deficiency overcoming mixing uneven, a kind of rectification tube mixer is provided, this rectifier tube drives by having the natural gas of certain pressure, after natural gas is passed through, whole rectifier tube can quickly rotate, mixed gas is played stirring action by atwirl rectifier tube, it is achieved the uniform mixing of mixed gas.This blender is not only simple in structure, and maintenance is convenient, but also can improve the service behaviour of electromotor, reduces the discharge of pollutant.
This utility model realizes the technical scheme of above-mentioned purpose: include blender cylinder, air inlet system and exhaust system, rectifier tube, rectification arm, ring flange, rectifier tube support, bearing block.Rectifier tube passes on left boss and rectifier tube support connects, and right side is connected by bearing block and rectifier tube support, is fixed on blender cylinder inner wall.Rectification arm is connected with rectifier tube by screw thread.The natural gas air inlet pipe of air inlet system and exhaust system is connected by boss and rectifier tube.
By such scheme, described air inlet system and exhaust system include natural gas air inlet pipe, air flow channel, gaseous mixture runner.Air flow channel is located at blender cylinder side, and mixed gas runner is located at blender cylinder opposite side, and natural gas air inlet pipe is located at below blender cylinder.The diameter of air flow channel is more than the diameter of natural gas air inlet pipe, and the centrage of air flow channel and mixer centerline overlap.
By such scheme, described rectification arm side has aperture equably
This utility model changes the blender of traditional static mixing.By the rotation of air rectifier tube, mixed gas is played stirring action, it is possible to realize the uniform mixing of two kinds of gases, improve the combustion conditions of diesel engine, decrease the discharge of pollutant.Having different operating modes in working process of diesel engine, it passes through electromagnetic valve for adjusting, changes the combustion vapour amount spraying into blender, to adapt to different operating modes, it is ensured that diesel engine can realize fully burning under any operating mode.Having simple in construction, maintenance is convenient, it is possible to increase the service behaviour of electromotor, reduces the feature of the discharge of pollutant.

Detailed description of the invention
For of the present utility model 26S Proteasome Structure and Function is expanded on further, below in conjunction with accompanying drawing, this utility model is elaborated.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, this utility model includes blender cylinder 1, air inlet system and exhaust system, rectifier tube 8, rectification arm 9, ring flange 3, rectifier tube support 6, bearing block 7.Air inlet system and exhaust system include air flow channel 2, natural gas air inlet pipe 4, mixed gas runner 5.Air flow channel 2 is connected through the air intake duct after turbocharging by ring flange 3, and mixed gas runner 5 connects air inlet pipe of diesel engine by ring flange 3.Natural gas air inlet pipe 4 is located at below blender cylinder 1.Air flow channel 2 is identical with mixed gas runner 5 diameter, and their centrage and mixer centerline overlap.In order to realize best combustion needs, enough air need to be provided, therefore the diameter of air flow channel 2 is more than natural gas air inlet pipe 4 diameter.Natural gas air inlet pipe 4 is connected by boss 11 and rectifier tube 8.Boss 11 is used for fixing bearing.Rectifier tube 8 passes on left boss 11 and rectifier tube support 6 connects, and right side is connected by bearing block 7 and rectifier tube support 6, is fixed on blender cylinder 1 inwall.Rectification arm 9 is connected with rectifier tube 8 by screw thread.Rectification arm 9 has aperture 10 on side equably, and natural gas is injected to air flow channel 2 by these apertures 10, mixes with air.When the natural gas with certain pressure is flowed into rectifier tube 8, then it is injected to air flow channel 2, meanwhile rectifier tube 8 quick rotation from jet apertures 10, mixed gas is played the effect of stirring.Discharge at mixed gas runner 5 after mixed gas mix homogeneously.
As a example by Fig. 5, LNG/ diesel dual-fuel diesel engine 22 air supply system principle is expanded on further.LNG air accumulator 12, is used for laying in liquefied natural gas, and in work process, liquefied natural gas flows in carburator 13 from LNG air accumulator 12, is vaporized.Owing to now gas pressure is higher, therefore reducing to suitable pressure through one-level pressure relief valve 14, gas pressure now is the most unstable, so natural gas is carried out buffering through surge tank 15 being stabilized to certain pressure.Natural gas via filter 16 after voltage stabilizing carries out being filtered to remove impurity, with blockage resisting natural gas line.Natural gas flow after filtering becomes a mandarin in gauge 17, and effusion meter 17 carries out statistical summaries to the flow velocity of natural gas, flow etc., it is simple to understand some parameters in diesel engine combustion.After effusion meter 17 flows out, pressure does not still meet combustion requirements, therefore is reduced pressure by second depressurized valve 18 again.After pressure meets combustion requirements, being injected in blender 21 by electromagnetic injection valve 19, uniformly mixing in case fully burning with the air after turbocharging.In order to burn in preventing blender body, it be flowed in gas pipeline, therefore between blender 21 and electromagnetic valve, be provided with spark arrester 20.
