Abstract
The utility model discloses a needling filtering felt of a Teflon coating which comprises the Teflon coating (1), a high-density fiber layer (2), a middle fiber layer (3), a base fabric layer (4) and a bottom fiber layer (5). The base fabric layer (4) serves as a substrate, the middle fiber layer (3) and the high-density fiber layer (2) composed of superfine or irregular fibers are sequentially installed on one side of the base fabric layer (4) toward a dust-facing surface, the bottom fiber layer (5) is installed under the base fabric layer (4), and the base fabric layer and the fiber layers are fixed through needling of a non-weave needling felt machine with four needle bases and double needles for opposite needling. The Teflon coating (1) is coated on the high-density fiber layer (2), and the thickness of the Teflon coating (1) is 0.5mm. The needling filtering felt is efficient, large in air treatment volume, corrosion resisting, acid-base resisting, hydrolysis resisting, low in cost, long in service life and high in cost performance.
Description
Technical field
The utility model relates to a kind of filter felt, is specifically related to a kind of teflon coating needled filtering felt.
Background technology
With regard to the bag-type dusting industry, bag-type dusting replaces electric precipitation gradually, and filter bag has been the very important parts in industrial dedusting field; Need periodic replacement; Being the important consumptive material of sack cleaner, also is " heart " of sack cleaner, and the result of use of sack cleaner is played a decisive role.Along with the environmental monitoring means strengthen gradually, environmental protection standard improves constantly, and the dust emission standard is brought up to PM2.5 by PM10, and concentration of emission is brought up to less than 30mg/Nm
3
Under operating mode deduster environment such as the big cement of factors vary such as humidity, acid-base value, oxygen content and temperature fluctuation, pottery oven dry and thermal power generation; The life-span of the filter bag of current use is short, fragile; The dust emission precision is low; There is pollution in atmospheric environment, far can not satisfies the needs of dedusting industry development.
To the dedusting industry, be badly in need of a kind of high efficiency, handle the novel filter felt of air quantity, corrosion-resistant, acid and alkali-resistance, hydrolysis greatly, to adapt to the requirement of present domestic environmental protection industry (epi) high speed development.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, a kind of high efficiency is provided, handles the teflon coating needled filtering felt of air quantity, corrosion-resistant, acid and alkali-resistance, hydrolysis, low cost, long-life, high performance-price ratio greatly.
For achieving the above object; The technological means that the utility model adopted is that a kind of teflon coating needled filtering felt comprises teflon coating, high-density fiber layer, mean fiber layer, base cloth layer, bottom fiber layer; With said base cloth layer is support; In base cloth layer to dust-collecting face one side mean fiber layer, high-density fiber layer are installed one by one, installing bottom layer fibrage under base cloth layer is fixed base cloth layer and each fibrage with non-woven mat eedle thorn; Outside the high-density fiber layer, coat teflon coating, coating layer thickness 0.5mm.
The beneficial effect of the utility model is: teflon coating has the characteristic of corrosion-resistant, acid and alkali-resistance, hydrolysis, and the coating cost of manufacture is low; Teflon coating is coated on the high-density fiber layer, and coating layer thickness is controlled at 0.5mm, has effectively resisted big air quantity dedusting environment, and adaptability is good, and the life-span is longer; With fixing each layer of nonwoven acupuncture, make surface porosity factor height, aperture little, the smooth laying dust that is difficult for, efficiency of dust collection is higher; This product low-cost high-efficiency, cost performance is high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; A kind of teflon coating needled filtering felt; Comprise teflon coating 1, high-density fiber layer 2, mean fiber layer 3, base cloth layer 4, bottom fiber layer 5; With said base cloth layer 4 is support, in base cloth layer 4 to dust-collecting face one side mean fiber layer 3, high-density fiber layer 2 is installed one by one, and said high-density fiber layer 2 is made up of ultra-fine or heterotypic fibre; At 4 times installing bottom layer fibrages 5 of base cloth layer, the non-woven mat eedle thorn of thorn is fixed base cloth layer and each fibrage with four needle stands, crosspointer; Outside high-density fiber layer 2, coat teflon coating 1, teflon coating 1 thickness is 0.5mm.The utility model product and canonical parameter deck watch:
Claims (2)
1. teflon coating needled filtering felt; It is characterized in that: comprise teflon coating (1), high-density fiber layer (2), mean fiber layer (3), base cloth layer (4), bottom fiber layer (5); With said base cloth layer (4) is support; In base cloth layer (4) to dust-collecting face one side mean fiber layer (3), high-density fiber layer (2) are installed one by one, installing bottom layer fibrage (5) under base cloth layer (4) is fixed base cloth layer and each fibrage with non-woven mat eedle thorn; Outside high-density fiber layer (2), coat teflon coating (1), teflon coating (1) thickness is 0.5mm.
2. teflon coating needled filtering felt according to claim 1 is characterized in that: said high-density fiber layer (2) is made up of ultra-fine or heterotypic fibre.
