Abstract

The invention relates to a folding air purification filter for a heating and ventilating air conditioner. The folding air purification filter comprises a frame and a composite gradient fiber filter screen, wherein the composite gradient fiber filter screen consists of a first non-woven filter material arranged on an outer layer and a second non-woven filter material arranged on an inner layer; and the first non-woven filter material and the second non-woven filter material are subjected to gradient combination to be folded and fixed in the frame. In the folding air purification filter, the conventional single-layer folding filter material is changed into a composite folding filter material with gradient, so that granules with a large size in air can enter the inside of the filter material to solve the problem of blocking in the process of forming filter cakes on the surface of the filter material, reduce the resistance of airflow and prolong the service life of the filter while the dust containing capacity is increased and the efficiency level of the filter is improved.

Description

technical field [0001] The invention relates to the field of gas purification in HVAC, in particular to a folded air purification filter for HVAC. Background technique [0002] Most of the existing gas purification filters for HVAC use single-layer filter material pleated air filters, and the filtration efficiency is generally classified as G3-M5 (coarse and medium-efficiency) according to the current European standards, and generally no second filter is arranged. device. Due to the use of single-layer pleated filter material, the fiber fineness and porosity of the filter material used in a filter are the same, so it can only capture particles in a certain particle size range. In addition, the V-shaped arrangement structure of the folded filter material deflects the airflow velocity into the filter material, and the particles affected by inertia in the gas tend to gather at the bottom of the V-shaped filter material, and gradually form an upwardly extending dust cake on the...
