Abstract

The utility model provides a high-efficient static electricity fibre filter which has the advantages of high efficiency, low noise, and low drag force. The high-efficient static electricity fibre filter is characterized in that a plurality of plain conductors and insulated conductors adhere to fibre filter material, the two conductors are respectively joined to a grounding end and a high voltage end of a high voltage power supply, so a fibre filtering layer builds a stronger and inhomogeneous electric field. The filter is matched with an air cleaning device composed of a low pressure fan, which is capable of realizing cleaning with indoor high cleanliness.

Description

High-efficient static electricity fibre filter
The utility model relates to the high efficiency electrostatic fiber-bed filter of using in a kind of air cleaning system.
High efficiency electrostatic fiber-bed filter (claiming static HEPA air cleaner abroad) is the external a kind of filter that occurred in recent years.It is by means of the electrostatic force between particle and the fiber, realizes traditional mechanical high efficiency particle air filter inaccessiable lower resistance of institute and filtration efficiency.This filter is formed with control of dust two parts by particle is charged, and air makes dust particle charged by corona discharge region earlier, and charged particle enters the fibrage that is added with electric field again and is captured.The dust particle dust arrester structure of this filter has various ways, generally be that nonmetal ripple dividing plate in the mechanical filter is changed metal partion (metp), simultaneously the whole ground connection of inlet air side dividing plate, the air side dividing plate all connects the high-pressure side of DC high-voltage power supply, makes and sets up stronger electric field in the fibrous filter layer.Owing to only every a filter material thickness (general 0.2-0.4 millimeter), therefore when voltage upwards fluctuates, cause two interpolar spark discharges easily between inlet air side and the air side dividing plate, puncture filter material.In addition, the filter material conductance increased when air humidity was higher, and insulaion resistance descends between ground connection pole plate and the high-pressure polar plate, and power supply can't partly be powered to particle collection.How to realize reliable insulation system, guarantee that the reliability of filter is the key issue of electrostatic fibre layer filter.Japanese kokai publication sho 58-114752, spy open in the clear 58-64145 patent documentation and have proposed result of the above problems, but complex structure, the processing and fabricating trouble has increased the filtration device structure resistance simultaneously.
The utility model provides a kind of better simply electrostatic fibre layer of structure filter that can overcome above-mentioned deficiency.
This filter is: vertically equidistant parallel adheres to some bare conductors and insulated conductor , And is folded to filter material in the framework on the plane of fibrous filter, is pasting the resilient double-sided tape of some hard between the filter material crease, and adhesive tape and lead do not overlap.One end of each bare conductor and insulated conductor accumulates two lead-out wires respectively, a ground connection, and another connects positive high voltage.Two interpolars apply and are lower than 5 kilovolts DC voltage, make and set up very strong inhomogeneous field in the fibrous filter layer.In this electric field, particle also is subjected to the polarization force from the height inhomogeneous field except that the Coulomb force that is subjected to producing owing to charged back.By means of these electrostatic force, improved the arresting efficiency of fiber greatly to particle.Simultaneously, deflection obviously increased after surface of filter medium adhered to lead, thereby reduced because the structural drag that the filter material deflection causes inadequately.
The utility model is described in further detail below in conjunction with embodiment.
