Abstract
The present invention utilizes the air-flow that tangentially enters this catcher to rotate, wash away and realize continuous automatic ash removing (regeneration), and prevents secondary fly-up by the inhibition utmost point.Compare with the porcelain filter of present application, arresting efficiency improves 10-20%, and oil consumption reduces 1.5-2%, and operating cost is low, has overcome the insoluble regeneration problem of porcelain filter.Be applicable on the various diesel-oil vehicles and use, and can be generalized to capture various diesel machine discharging particulate.
Description
This invention belongs to the external existing emission of diesel engine particulate equipment for after-treatment of emission of diesel engine particulate equipment for after-treatment and mostly is ceramic honeycomb filter, the domestic ceramic foam filter (identifying in 89 years) of having succeeded in developing.The charcoal cigarette catcher arresting efficiency of this filtering type heals high-drag more greatly.Therefore, its economic line efficiency 50%-60%, and make vehicle fuel consume increase 1.5-2.0%; Along with the increase of the charcoal cigarette that is captured, resistance increases to certain value will remove these carbon granules promptly usually with the realization of burning way, and complicated mechanism and the control apparatus of a cover be arranged, since burning, ceramic element requirement periodic replacement.Capturing with electrostatic precipitation technology that the charcoal cigarette eliminates smoke is that a typical case of electric precipitation uses, but electric cleaner is bulky, and shake is beaten deashing etc. and is difficult to be used on the automobile.IEEEVoL.IA-19.No.-6 report Masuda etc. propose the imagination of mobile belt automobile electrostatic smoke devices, wipe realization (regeneration) with receiving after charcoal cigarette on the line belt is with the roller compacting off with scraping blade.Complex structure can't be used.
It is that the composite dedusting technology that basic static combines with whirlwind has improved the efficient that captures the charcoal cigarette that the present invention adopts with static, washes away real automatically continuous deashing (regeneration) with automobile exhaust.
The present invention mainly utilizes electrostatic principle that the charcoal cigarette is captured, and has improved arresting efficiency and has been up to more than 95%; Utilize exhaust self kinetic energy to wash away and realize continuous automatic ash removing, solution insoluble in filter " regeneration " (deashing) problem has reduced resistance (energy-conservation), the complete machine no-rotary part, the reliability that improved simple in structure: removed as easily damaged partss such as filter cores, improved the preprocessor life-span.

This invention is by following scheme implementation
The exhaust of diesel engine enters smoke-reducing device by tangent air inlet [10], by [11], rotates in the ring-like electric precipitation space that [4] constitute.The electrostatic high-pressure power supply [14] of car accumulator [15] power supply is high voltage supply prickle discharging pole [5], and air-flow carbon granules when the corona field between [5] and [4] is charged and driven to collector [4] by electric field force.Pressurized air in the automobile compressed pneumatic pump [13] enters in the cavity of insulator [3] by conduit [9], to keep the insulation of high-field electrode [11] [5] and grounding shell [4].Being deposited on carbon granule on the collector [4] is rotated air-flow and pushes cone to and go forward side by side into ash bucket.Form in tapered inhibition electrode [7] and the cone [12] and suppress electric field and suppress in carbon granule and the ash bucket carbon granule and fly upward again among gas and get rid of from inner core.Clean air is discharged from outer pipe [1], realizes the purification to automobile exhaust.
