Abstract

The utility model provides a gradient carbon shift non woven fabric for filtering and purifying air. Heavy denier terylene fiber and fine denier terylene fiber respectively get through two feed hoppers, to be carded and folded again to be a reticulation. The upper layer surface of the reticulation is the heavy denier terylene fiber, and the lower layer surface is the fine denier terylene fiber, the fiber density from the upper layer surface to the lower layer surface of the reticulation is in a gradient array, namely, the fiber density from the upper layer surface to the lower layer surface is gradually increased, the heavy denier terylene fiber layer has the thickness of 5-7mm, and the largest aperture of 80 to 120 micromter, and the fine denier terylene fiber layer has the thickness of 2 to 3mm, and the largest aperture of 50 to 70 micrometer. The external surface layer of the fine denier terylene fiber layer is coated with mixed liquor of black active carbon and colophony, and has the thickness of 1 to 2mm, and the largest aperture of 50 to 70 micrometer. The mixed liquor is arranged at the exhaust outlet of an air conditioner, and has the functions of dust removal, disinfection and deodorization; thereby the indoor air quality can be greatly improved.

Description

Gradient type carbon shifts nonwoven fabric

Technical field

The utility model relates to a kind of nonwoven fabric of filtering and purifying air of being used to.

Background technology

The device that filters at present and purify air, generally all huger, the cost height.

Summary of the invention

In order to reduce equipment energy consumption, improve the efficient that purifies air, the utility model provides a kind of gradient type carbon to shift the nonwoven fabric filtration and purifies air, it is to pass through two feeding hoppers respectively by coarse denier terylene fiber and fine-denier polyester fiber, carry out combing and folding again be paved into netted, the last aspect of net is the coarse denier terylene fiber, subsurface is a fine-denier polyester fiber, last aspect to the density of subsurface material of net is arranged in gradient, promptly the fibre density from last aspect to subsurface increases gradually, the fibrolaminar thickness of coarse denier terylene is 5-7mm, the maximum diameter of hole is at 80-120 μ m, the thickness of fine-denier polyester fiber layer is 2-3mm, the maximum diameter of hole is at 50-70 μ m, extexine at the fine-denier polyester fiber layer, scribble black activated carbon and rosin mixed liquor, its thickness is 1-2mm, the maximum diameter of hole is at 50-70 μ m, advantage is the exhaust outlet that this nonwoven fabric is placed air-conditioning, and the disinfecting, deodorizing function is arranged, and can improve indoor air quality greatly, also can be arranged at medicine, electronics, workshops such as chemical industry, the laboratory, filter and purify air, cost is low, the efficient height.

Description of drawings

Accompanying drawing is a section structure schematic diagram of the present utility model.

The specific embodiment as shown in drawings, the webbed coarse denier terylene fiber 1 in upper strata, its thickness be greater than the fine-denier polyester fiber 2 of lower floor, from the upper strata to lower floor, the density of material increases gradually, orlop below fine-denier polyester fiber 2, scribbles activated carbon and rosin mixed liquor 3, during filtered air, the one side of coarse denier terylene fiber 1 places air inlet one side, and a side of fine-denier polyester fiber 2 places air outlet one side (purifying air after the filtration).

Claims
