Description
Technical field
The invention belongs to technical field of motorcycles, specifically, particularly a kind of motor exhaust cleaning system.
Background technique
Motorcycle exhaust discharges, and major pollutants have solid aerosol, carbon monoxide, carbon dioxide, hydrocarbon, oxynitrides, lead and oxygen sulfur compound etc.The composition of solid suspended particle is very complicated, and has stronger adsorptive power, can adsorb various metallic dust, strong carcinogen BaP and pathogenic microorganism etc.Solid suspended particle enters human lung with breathing, and to collide, to spread, the mode such as deposition is trapped in the different parts of respiratory tract, causes respiratory disease.When suspended particulate runs up to critical concentration, just formation malignant tumour can be excited.In addition, suspending particulate matter can also directly contact skin and eyes, blocks hair follicle and the sweat gland of skin, causes dermatitis and eye conjunctivitis, even cause corneal injury.Therefore, the solid suspended particle discharge reduced in motorcycle exhaust is most important.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of motor exhaust cleaning system that effectively can reduce solid suspended particle discharge.
Technological scheme of the present invention is as follows: a kind of motor exhaust cleaning system, comprise outlet pipe (11) and silencing apparatus (13), the import of silencing apparatus (13) front end is connected with outlet pipe (11), in the top of described silencing apparatus (13), double purification cylinder (2) is set, one end of double purification cylinder (2) is sealed by sealing cover (3), at the other end of double purification cylinder (2), end cap (4) is installed, this end cap (4) is provided with offgas outlet (5), filter core (6) is provided with in described double purification cylinder (2), this filter core (6) is straight tube structure, the endoporus of filter core (6) is communicated with described offgas outlet (5), and form annular cavity (7) between the inwall of filter core (6) and double purification cylinder (2), first separation cylinder (1) is fixed in the below of described double purification cylinder (2), this first separation cylinder (1) is up big and down small taper, in the bottom of first separation cylinder (1), there is liquid storage room (9), the sidewall of first separation cylinder (1) upper end offers inlet exhaust gas, this inlet exhaust gas is connected with the one end of bend pipe (12), and be provided with spiral vane at inlet exhaust gas place, the other end of described bend pipe (12) is connected with the outlet of silencing apparatus (13) rear end, air pipe (8) is provided with in described first separation cylinder (1), the top of this air pipe (8) and the diapire of double purification cylinder (2) fix, and the endoporus of air pipe (8) is communicated with described annular cavity (7) by the vent on double purification cylinder (2) diapire.
Adopt above technological scheme, the tail gas of discharging from silencing apparatus flows to first separation cylinder through bend pipe, air-flow produces strong rotation under the guiding of spiral vane, air-flow is entered downwards in first separation cylinder twist, the grit that density is large is thrown toward first separation cylinder inwall under centrifugal action, and fall to liquid storage room along barrel under gravity, adsorbed by the machine oil of splendid attire in liquid storage room; The air-flow rotated shrinks to center flow in first separation cylinder, upwards formation secondary vortex flow flow to the annular cavity in double purification cylinder through air pipe, enter filter core endoporus after falling the less grit of density by filter element filtering, finally discharge from the offgas outlet end cap.
The present invention removes grit larger in tail gas by first separation cylinder, grit less in tail gas is removed by double purification cylinder, under twice catharsis, effectively can reduce the discharge of solid suspended particle in motorcycle exhaust, provide possibility for motorcycle realizes zero-emission.Tail gas forms eddy flow in first separation cylinder, can also play the effect of heat radiation, cooling, make the exhaust temperature flowing to filter core enough low, thus avoid the filter core that to ignite because exhaust temperature is too high; Meanwhile, flow in the tail gas of filter core and there is no large grit, filter core blocking can be reduced, make exhaust more smooth and easy, thus it is flame-out to prevent motor to occur.
Described filter core (6) forms by multilayer waveform filter paper is coated successively.Above structure on the one hand structure is simple, and be easy to processing and fabricating, cost is low; On the other hand, filter the effective of little grit, the effect of tail gas clean-up can be improved further.
One end and the sealing cover (3) of described filter core (6) offset, sealing cover (3) is placed on double purification cylinder (2) admittedly, the other end of filter core (6) is inserted in the annular boss (4a) of end cap (4) end, and this end of filter core (6) and end cap (4) abut against, described end cap (4) is sleeved on double purification cylinder (2), and by being welded and fixed.Above structure is not only simple, reliable, be easy to processing and fabricating, and filter core is good in double purification cylinder inner position, can not loosen, and more renew cartridge is not only convenient but also quick to remove sealing cover.
Conveniently arrange on vehicle frame, and it is firm to guarantee that double purification cylinder lifts on vehicle frame, is welded with near the position at middle part on described double purification cylinder (2) top and hangs journal stirrup (10).
The diapire of described liquid storage room (9) has oil drain out, and this oil drain out is sealed by oil extraction lid; The roof of described liquid storage room (9) has filler opening, and this filler opening is sealed by feed cover; The sidewall of described liquid storage room (9) has viewing window, in this viewing window, is embedded with glass sheet.The machine oil of liquid storage room and the solid suspended particle adsorbed can be discharged by opening oil extraction lid by above structure, and open feed cover and can to annotate clean machine oil, make the machine oil in liquid storage room keep absorption vigor; The situation in liquid storage room can be observed at any time, so that hold the opportunity changing machine oil by viewing window.
Beneficial effect: the present invention is by cyclonic separation and filter absorption twice purification, effectively can reduce the discharge of solid suspended particle in motorcycle exhaust, and can smooth in exhaust be guaranteed, and there is the features such as design is ingenious, structure is simple, cost is low, all applicable on various types of motorcycle.
