Compared with the prior art, the effect of filtering harmful gas and water in the air can be improved, meanwhile, air inlet resistance can be effectively reduced, and the service life of the filter element is prolonged.
Description
Technical field
The utility model relates to the air-filtering technical field, specifically a kind of non-woven fabric air filter material and filter core.
Background technology
In order to make the air-conditioning filter core have multiple function, such as: remove pernicious gas in the air, dehumidifying etc. make the cleanliness factor of environment higher; Present stage is generally adopted the means of in air filter material, filling additive, such as interpolation, and dehumidizer such as silica-gel desiccant, calcium carbide; Ion exchange resin, medical stone, bentonite, montmorillonite; Charcoal, bamboo charcoal, zeolite etc.And the adding of additive often causes air filter material thickness to increase, and air inflow sharply reduces under the equal admission pressure, and crushing increases, and causes problems such as equipment power dissipation is big, the shortening in service life of filter core, air-filtering decrease in efficiency.For this reason, we have proposed following invention.
Summary of the invention
The utility model is to the deficiency that exists in the prior art; Propose a kind ofly can effectively remove pernicious gas such as sulfur dioxide, toluene in the air; Dust granule in simultaneously can filtered air; Reduce air humidity, and can under lower power consumption, significantly reduce the air filter material and the filter core of air inlet resistance, prolongation service life of equipment.
The utility model can reach through following measure:
A kind of air filter material; Comprise nonwoven filter course and filtering additive layer; It is characterized in that being provided with the two-layer nonwoven filter course, filtering additive layer is fixed between the two-layer nonwoven filter course, and filtering additive layer is made up of the filtering band that is parallel to each other more than two.
The distance range of two above filtering band each intervals in the additive of filtering described in the utility model layer is less than 300 mm.
The thickness range of the filtering band in the additive of filtering described in the utility model layer is less than 2 cm, to be implemented under the less air inlet resistance effect that improves dehumidifying and dispel pernicious gas.
The band of filtering described in the utility model can be made up of activated carbon granule; Adding man-hour through duster isolation dusting zone; Make the parallel distribution of filtering band of adopting active carbon powdered carbon particle to process; Active carbon powdered carbon grain fineness scope will be fixed between the two-layer nonwoven filter course by the filtering additive layer that the filtering band that is parallel to each other more than two constitutes through heating, compacting less than 2mm then, and the filtering band also can be by dehumidizer such as silica-gel desiccant; Perhaps calcium carbide, ion exchange resin, medical stone, bentonite, montmorillonite, one or several particles process in charcoal, bamboo charcoal, the zeolite etc.
A kind of air-filtering filter core; Comprise that longitudinal folding by air filter material is undulatory body; And the skeleton that is used for supporting body; The filter material that it is characterized in that said body employing is made up of two-layer nonwoven filter course and filtering additive layer; Wherein filtering additive layer is fixed between the two-layer nonwoven filter course, and the filtering additive layer is made up of the filtering band that is parallel to each other more than two, and the distance of two above filtering band each intervals is less than 300 mm
.
A kind of air-filtering filter core that proposes in the utility model; Wherein longitudinal folding by air filter material is undulatory body; Because it adopts the air filter material of the filtering additive layer that is provided with to process; And the filtering additive layer of this air filter material is made up of the filtering band that is parallel to each other more than two, two above filtering bands each other at interval distance less than 300 mm
, Thereby make on the body that folds after processing and to form zebra shape striped, and then in the cleaner course of work, effectively reduce the air inlet resistance, to reach purposes such as reducing crushing, raising air-filtering efficient, prolongation service life of equipment.
The utility model compared with prior art can effectively be removed airborne pernicious gas and moisture under the situation that does not increase crushing.
