The diameter of graphite fibre stick is micron dimension, is connected to one end of stainless steel bar.This fiber bundle structure can effectively increase in space
Corona discharge density improve efficiency of dust collection so that the more efficient particulate matter by air becomes state-of-charge.
A method of the raising air purification efficiency based on graphite fibre, specifically includes the following steps:
S1: the charged stage: air-flow to be processed sucks clarifier, flows through high-field electrode and makes particulate matter charged；
S2: collection phase: electrically charged particle is moved to collecting board under the action of electric field force and is adsorbed on collecting board；
S3: purified air is blown out by purification system two sides of the bottom, completes purification.
Further, for step S1, cfentrifugal blower sucks air to be clean in air cleaning system, to net
The air of change initially enters charged system.
Further, the charged system includes graphite fibre electrode, stainless steel plate electrode and cross bar, the graphite fibre
Electrode and stainless steel plate electrode gap are alternately fixed on cross bar, and high direct voltage is added between graphite fibre electrode and stainless steel plate electrode
Power supply, while using stainless steel ring as grounding electrode.
Further, the cross bar uses polythene material.
Further, the graphite fibre electrode is made of the graphite fibre of hundreds of micron dimensions, and stepped row
Column, while graphite fibre is uniformly closely packed on metab；Make corona point in space relatively uniform with this, so that
The higher probability of the particulate matter in air flowed through it is charged, so that air purification efficiency can be improved.
Further, the graphite fibre is cylinder.
Further, for step S2, the air stream containing electrically charged particle object is continued sucking and collected by cfentrifugal blower
In the electric field of column and punched-plate composition, punched-plate ring-type, which is uniformly centered around, is collected around column, and punched-plate is connected with column both ends are collected
D.C. regulated power supply radially generates electrostatic field between collection column and punched-plate with this；Charged species in air pass through quiet
It when electric field, is acted in electric field force and is detached from air trajectory, moved to the direction for collecting column, be finally adsorbed on the surface for collecting stick.
Further, for step S3, purified air is sucked bottom from punched-plate by cfentrifugal blower, by bottom
Two sides blowout.
The utility model has the advantages that compared with prior art, it is strong that the present invention by the electrode of graphite fibre Shu Zucheng generates stability
Single-pole, due to graphite Shu Benshen physico-chemical property and its edge shape of sharp solid matter, high with single-pole generation efficiency,
Ozone generation rate is low, erosion-resisting advantage.

Specific embodiment
A specific embodiment of the invention is set forth now in conjunction with attached drawing.
A method of the raising air purification efficiency based on graphite fibre, specifically includes the following steps:
S1: the charged stage: air-flow to be processed sucks clarifier, flows through high-field electrode and makes particulate matter charged；
S2: collection phase, electrically charged particle are moved to collecting board under the action of electric field force and are adsorbed on collecting board；
S3: purified air is blown out by purification system two sides of the bottom, completes purification.
For step S1, cfentrifugal blower 7 sucks air to be clean in air cleaning system, air to be clean
Charged system 3 is initially entered, polyethylene cross bar 11 is installed at the air inlet of charged system 3, large volume foreign matter can be prevented
It falls into purification system device.
The charged system 3 includes graphite fibre electrode 9, stainless steel plate electrode 10 and polyethylene cross bar 11, the graphite
