High-CADR EMF filtering system and air purifying equipment

Abstract

The invention relates to a high-CADR EMF filtering system and air purifying equipment. The high-CADR EMF filtering system comprises an EMF assembly and a filtering frame assembly; the EMF assembly comprises a cylindrical ion net; and the filtering frame assembly comprises sleeve-shaped HEPA filter paper arranged outside the EMF assembly in a sleeving mode and a cylindrical external discharge net located on the outer side of the HEPA filter paper. A sleeve-shaped HEPA filter paper structure is used, air enters from the external discharge net, particulate matters and microorganisms in the air are intercepted by the HEPA filter paper after the air enters the external discharge net, a large number of charged ions exist in an HEPA space due to the electric field action of the external discharge net and the ion net, the charged ions are pulled by the action of electric field force after being adsorbed to the surfaces of the microorganisms and are destroyed so as to kill pathogenic bacteria, the air passes through the HEPA first, for mahcine design, such that the area of the HEPA can be substantially improved, such that the wind resistance of a machine can be reduced, the CADR can be increased, the noise and the power can be reduced, and the CADR can be improved by 50%, the noise can be reduced by 12 DB, the power can be reduced by 23 W, and the ozone can be reduced by 40% compared with an existing structure under the same size condition according to the actual measurement condition at present.

Description

technical field [0001] The invention relates to the technical field of air purification, more specifically, to a high CADR EMF filter system and air purification equipment. Background technique [0002] The existing EMF structure is usually composed of three parts arranged side by side from bottom to top: the lower discharge network (negative pole), the ion network (positive pole), and the upper discharge network (negative pole); during work, the air enters from the lower discharge network and passes through the lower discharge network successively, and the ions Grid, upper discharge grid, HEPA is between the ion grid and the upper discharge grid, and close to the upper discharge grid; between the lower discharge grid and the ion grid, a high-voltage grid is composed of positive and negative electrodes to discharge the air, so that the particles in the air are carried The charge is then adsorbed by HEPA when it passes through HEPA; due to the interaction between charge and e...
