Description
Technical field
The invention belongs to technical field of motorcycles, specifically, particularly a kind of motorcycle exhaust double purification device.
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 motorcycle exhaust double purification device that effectively can reduce solid suspended particle discharge.
Technological scheme of the present invention is as follows: a kind of motorcycle exhaust double purification device, the straight tube structure that double purification cylinder (2) is open at both ends, the front end of this double purification cylinder (2) is sealed by sealing cover (3), at the rear mounting end lid (4) of double purification cylinder (2), 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), double purification cylinder (2) diapire offers vent (1).
Adopt above technological scheme, arrange vortex type a separator in the below of double purification cylinder, the outlet of this vortex type a separator is communicated with the vent of double purification cylinder diapire, and the import of vortex type a separator is connected with silencing apparatus by bend pipe.The tail gas of discharging from silencing apparatus flows to vortex type a separator through bend pipe, the large grit of density is removed by vortex type a separator, tail gas upwards forms the vent of secondary vortex flow bottom double purification cylinder and flow to annular cavity in double purification cylinder, 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 matches with vortex type a separator, grit larger in tail gas is removed by a separator, 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.
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.
Front end and the sealing cover (3) of described filter core (6) offset, front end and the sealing cover (3) of filter core (6) are fixed together, the rear end of filter core (6) is inserted in the annular boss (4a) that end cap (4) front end is integrally formed, and the rear end of filter core (6) and end cap (4) abut against.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 (8).
Beneficial effect: the present invention removes on the basis of larger grit in tail gas at vortex type a separator, grit less for density can be filtered out, thus effectively reduce the discharge of solid suspended particle in motorcycle exhaust, there is the features such as design is ingenious, structure is simple, cost is low, all applicable on various types of motorcycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1 and Figure 2, double purification cylinder 2 is the straight tube structure of open at both ends.The front end of double purification cylinder 2 is sealed by sealing cover 3, and sealing lid 3 is sleeved on double purification cylinder 2, is removably connected between the two by screw thread or other similar mode; Certainly, as equivalent replacement, sealing cover 3 also can adopt welding to fix with double purification cylinder 2.Arrange end cap 4 in the rear end of double purification cylinder 2, this end cap 4 is sleeved on double purification cylinder 2, and is fixed by welding and double purification cylinder 2.Offer manhole at the center of end cap 4, and arrange offgas outlet 5 at the rear side of end cap 4, this offgas outlet 5 is short tube, and is structure as a whole with end cap 4, and offgas outlet 5 is communicated with the through hole at end cap 4 center.
As shown in Figure 1 and Figure 2, filter core 6 is provided with in double purification cylinder 2, this filter core 6 is the straight tube structure of open at both ends, preferably form by multilayer waveform filter paper is coated successively, the shaft axis of filter core 6 and the shaft axis of double purification cylinder 2, form annular cavity 7 point-blank between the inwall of filter core 6 and double purification cylinder 2.Front end and the sealing cover 3 of filter core 6 offset, and the front end of filter core 6 can be fixed together with sealing cover 3.The rear end of filter core 6 is inserted in the annular boss 4a that end cap 4 front end is integrally formed, and the rear end of filter core 6 and end cap 4 abut against, and the endoporus of filter core 6 is communicated with offgas outlet 5.Be welded with near the position at middle part on double purification cylinder 2 top and hang journal stirrup 8, can by double purification cylinder 2 suspended fixing on the vehicle frame of motorcycle by this suspension journal stirrup 8.
