specific Embodiment

[0052] 1. Processing method:

[0053] The present invention adopts the following method to carry out electrostatic electret or charged treatment to new or cleaned electret or dielectric filter material;

[0054] 1. Discharge treatment method:

[0055] (1) Dielectric barrier discharge:

[0056] In industrial production, the charging of most electret filter materials is realized by corona discharge to a single wire, so the total charge is large, and in the present invention, the woven electret filter material is , or multilayer filter materials made of cotton yarn, organic fiber cotton, activated carbon, etc., are placed in an electric field for treatment, so a specially designed high power density electric field is required;

[0057] Considering that electret and many non-conductive filter materials are dielectric materials, placing the dielectric material between two high-voltage electrodes for treatment is essentially a dielectric barrier discharge treatment method, which i...

Abstract

The invention discloses a dielectric filtration material charged regeneration device and method. The method comprises putting an electret or other dielectric filter material finished products as barrier mediums in a voltage alternative electric field so that dielectric barrier discharge is formed, or putting the electret or other dielectric filter material finished products in a corona field under high direct voltage so that corona-dielectric barrier discharge is formed. Through discharge, electrostatic electret charging and / or electrostatic charging is realized so that filter or finished product performances are improved, and the cleaned filter material or product is re-charged and is subjected to disinfection. The dielectric filtration material charged regeneration device comprises a filter material, a positive electrode plate, a negative electrode plate, an AC or DC high voltage generator and a power supply. Through the device and method, filter material or finished product performances are improved, the cleaned filter material or product is re-charged and the disposable product can be recycled. The method has simple processes, is convenient for operation, reduces material and resource wasting and realizes filter material recycle.

Description

technical field [0001] The invention belongs to the technical field of air filter materials, and in particular relates to a charging regeneration device and method for dielectric filter materials. Background technique [0002] The deteriorating air environment has seriously endangered human health. Modern society requires high-efficiency and low-resistance air filter materials. Traditional filter materials either have unsatisfactory filtration performance or are too expensive. Commonly used fiber filter materials mainly rely on Brownian diffusion, Interception, inertial collision and direct interception and other mechanical blocking effects are used to capture dust. For particles with a particle size of less than a few microns, the filtering effect is very poor. If the filter fiber has a strong electrostatic charge, in addition to the original mechanical blocking effect, Relying on Coulomb force to directly attract charged particles in the gas phase and capture them, or indu...
