Description
Technical field
The present invention relates to the Motor Vehicle air inlet system, especially relate to the Motor Vehicle air inlet dust collection method and the device that adopt the electric power dedusting.
Background technique
In Motor Vehicle, in order to reduce the wearing and tearing of motor, must the air that get in the cylinder be filtered, promptly remove dust in air and impurity, the device of bearing this effect is called air-strainer.
The kind of air-strainer is a lot, but basic principle is identical, promptly extraneous dust laden air behind the filter element filtering of filter cleaner, filtering be prone to make the dust and the impurity of engine producing wearing and tearing.But air-strainer also is a Motor Vehicle, and the easiest inefficacy damages, changes the most frequent parts.
Because the micro channel that has many permission air to pass through in the filter core of air-strainer; Thereby particle diameter is blocked by filter core greater than the dust of micro-pore diameter; Particle diameter then has two kinds of possibilities less than the dust of micro-pore diameter: first; Pass micro channel and get into cylinder, make cylinder produce the part of wearing and tearing and becoming fume in the tail gas; The second, part small particle diameter dust is piled up delay in micro channel, causes the obstruction of micro channel.The obstruction of a plurality of micro channels just makes the filter core resistance increase, and therefore air-strainer just lost efficacy and scrap.Therefore, the dust of small particle diameter is the basic reason that causes air-strainer to lose efficacy and damage, and has only and reduces the little dust quantity that gets into air-strainer, could prolong its working life.
Also there is an other deficiency in air-strainer in addition, and the big particle diameter dust of promptly being intercepted and captured by filter core can't be discharged filter cleaner, does not have the measure of any minimizing dust, needs periodic replacement filter core or whole air-strainer.

Embodiment
Below in conjunction with accompanying drawing, preferred implementation of the present invention is described.
Fig. 1 is the structural representation that is fit to first embodiment of vertical installation; Fig. 2 is the A-A sectional view of Fig. 1.As shown in Figure 1, this electric power dust removal apparatus adopts flange to be connected in the Motor Vehicle air inlet pipeline, comprises tubular dust collecting electrode 10, is positioned at the corona discharge electrode 30 of tubular dust collecting electrode shaft core position and is positioned at the outer high-voltage power 20 of Motor Vehicle air inlet pipeline.
The top and bottom of tubular dust collecting electrode 10 are equipped with porous slab 12 and following porous slab 14 respectively.Upper and lower porous slab 12,14 can be processed by metallic material or insulating material, preferably adopts insulating material, strengthening the insulating effect to high pressure, and has the circular hole that a plurality of permission air-flows or dust pass through on the porous slab.
On the following porous slab 14 supported joint 16 is housed, on the last porous slab 12 wiring joint 18 is housed.One end of high voltage cable 21 connects the negative pole of high-voltage power 20, and the other end passes input adapter 22 and is connected with corona discharge electrode 30 with wiring joint 18.The positive pole of high-voltage power 20 is connected with the shell of tubular dust collecting electrode 10, and reliable ground.This negative high voltage Placement has not only guaranteed Electrical Safety, and helps the electric power dedusting and reduce noise.
And said high-voltage power 20 can be a DC high-voltage power supply; Also can be ac high voltage source, or pulsed high voltage generator, the electric power of said high-voltage power 20 is taken from motor generator or storage battery; Boost through inverter circuit, this is conspicuous to those skilled in the art.
On the shaft core position of tubular dust collecting electrode 10, corona discharge electrode 30 is housed, it is by the wiring joint 18 of upper end and the supported joint 16 common locked positions of lower end.This corona discharge electrode 30 can be made with conductor; Can adopt nonmetallic material such as metal or graphite to process, can process bar-shaped, tubulose or wire, its appearance can be smooth; Also can have projection; Can think prickle shape, zigzag fashion, or stud-shaped, be preferably a coarse thread double-screw bolt that satisfies GB GB193-81 regulation.Adopt the advantage of coarse thread double-screw bolt to be: the first, to be convenient to make, cost is low; The second, thread flexuose triangular in shape according to the point discharge principle, under the effect of high voltage electric field, is easy to generate the required even coronal discharge of dedusting as shown in fig. 1.
First embodiment's working procedure is: ambient air passes through suction port 11 and last porous slab 12 from suction tude (compact car) or intake silencer (large car); Flow into the high-tension electricity place of the generation between tubular dust collecting electrode 10 and the corona discharge electrode 30; Receive the effect of high voltage electric field; Dust in air accumulates on the inwall of tubular dust collecting electrode 10, receives the triple role of Motor Vehicle vibration, gravity and air-flow, and these dusts that gather are through falling into the water of dust collecting tank 40 behind the following porous slab 14.Regularly open dust discharge valve 48, the dust that gathers just is discharged from, and clean air 50 directly gets into engine air passages (when using separately) or gets into air-strainer (when series connection is used) through the air outlet.
