To generate the air stream along flow path；Corona ionization ionizes the air stream flowed through, generates precharge particulate matter；Polarization one
A fabric filter improves purification efficiency as carrier, that is, is acted on precharge particulate matter, and guide air stream stream
Included this fabric filter of precharge particulate matter, to enhance its ability for removing particulate matter, it is characterised in that make to polarize
The step of fabric filter polarizes can generate the potential difference between upstream insulating electrode and the conductive electrode of opposite downstream, under
It swims conductive electrode and fibrous filter media and is uniformly dividing multiple position physical connections with entire filter media surface.This is specially
Benefit could not provide CONSTRUCTED SPECIFICATION information, casting distance, CADR and similar information.
Patent US6364,935B1A, Blueair AB, 6.5.1997 describe a kind of particulate matter cleaned in gaseous fluid
Equipment.The equipment includes: a permanent just or permanently negative high voltage power source；One filter separated with the power supply, it is described
It is about 1 micron by diameter or fine filtering medium that the fiber greater than 1 micron forms that filter, which includes one, and the fiber
Between average distance be about ten times of the fibre diameter, the fiber is easily polarized when encountering power plant's charge；For inciting somebody to action
The fluid flows through the component of the high voltage power supply and the filter；Other than the particulate matter passes through the filter,
The filter is not necessarily to external charging component.
The prior art fails to describe the importance of air cleaner equipment and technology problem, such as: the replacement and dimension of corona ionization needle
Shield is difficult and corona ionization needle is easily contaminated with grounding electrode.
Summary of the invention
The main purpose of the utility model is to provide the replacement and maintenance that can overcome or at least reduce corona ionization needle
A kind of difficult and corona ionization needle and grounding electrode problem easily easy to pollute corona discharger, and include the corona discharger
