Problems solved by technology

[0006] The present invention aims at the problem that the existing filter materials mostly use non-woven cotton for filtering, and the filter effect is average. Now that the PM2.5 often exceeds the standard, the original filter materials are difficult to play a role, and provide a filter for the fresh air system. fiber filter material

Abstract

The invention relates to the field of air filtration, and discloses a fibrous filtering material used for a fresh air system. According to the technical scheme, the fibrous filtering material comprises a first layer namely a glass fiber layer, a second layer namely a chemical synthetic fiber layer, a third layer namely a plant fiber layer and a fourth layer namely a bacterial fiber layer from top to bottom; a hot melt adhesive is adhered between the first layer and the second layer; the hot melt adhesive is adhered between the second layer and the third layer; and the hot melt adhesive is adhered between the third layer and the fourth layer. The fibrous filtering material provided by the invention solves the problems of general filtering effect due to usual using of non-woven cotton in a conventional filtering material for filtration, and difficulty of the conventional filtering material in exerting effects under the condition that conventional PM2.5 often exceeds standards.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to a fiber filter material used in a fresh air system. Background technique [0002] The fresh air system is an independent air treatment system composed of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system is composed of a fresh fan and pipe fittings. The outdoor air is purified by the fresh fan and introduced into the room, and the indoor air is exhausted through the pipe; the ductless fresh air system is composed of a fresh fan. The treasure discharges the indoor dirty air. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office areas due to the large amount of engineering, while the ductless fresh air system is more suitable for home use because of its easy installation. [0003] Air pollution has been listed as one of the three ...
