Description
Technical field
The present invention relates to a kind of plasma purifier, the air purification channel of specifically a kind of plasma purifier.
Background technology
The air purification channel of common plasma purifier, radio pole and collector are mostly pulled formula using line or are adopted
With spool formula, but the effect is unsatisfactory, and the better radio pole of effect and collector, use rack-and-pinion, but rack exists at present
Installation in air purification channel is often vertical, and rack and the direction that air flows are parallel, and since rack has width,
Radio point is at the crown end on rack both sides, therefore, a purification blind area band is just will produce on rack width face, is especially flowed through
Wind speed it is higher when, the air of pollution is possible to escape from this blind area band；When having the vertical installation of rack again and air
Flow direction is parallel, and the insulator for mentioning a screw rod is to be transversely mounted, and in order to extend insulation distance, the insulator at screw rod both ends must be stretched
Enter purification channel a distance, in this way, the distance that both ends insulator stretches into purification channel adds up, just accounts for air purification channel
The diameter of nearly half, and rack cannot be installed below insulator, the space of vertical direction above and below that non-both ends insulator has added
Account for the space of the nearly half in gross decontamination channel, this space distal end again far from radio pole, therefore, this space there is
Prodigious loophole, the clean-up effect of air has been seriously affected.
In view of drawbacks described above, creator of the present invention obtains this creation finally by prolonged research and practice.
