Abstract
The utility model discloses a kind of resistance to oxidation PPS needled filtering felt, including basic unit, filter layer, the bottom of basic unit's upper and lower surface are arranged on, and are arranged on the top layer for filtering layer surface；The top layer is expanded microporous polytetra fluoroethylene-EPTEE more than a layer（ PTFE ）Thin film, is formed with filter layer hot pressing；The filter layer is carbon fiber layer, adds B in carbon fiber layer4C and SIC materials；The bottom is polyimide fiber layer；The basic unit is one or more composition in PPS fibrous layers and glass layer, PTFE fiber layer, P84 fibrous layers；By the use of top layer of the carbon felt as filter felt made by carbon fiber, adding special material in carbon felt increases the toughness of resistance to oxidation and integral filter felt of material, while improve acid resistance, alkali resistance and corrosion resistance by force, resistant to hydrolysis ability, strengthen material performance, filtering accuracy is high.
Description
Technical field
This utility model is related to a kind of filtering material, more particularly to a kind of antioxidative PPS needled filtering felts.
Background technology
Needled filtering felt is used for the gas cleaning of the industries such as white carbon black, iron and steel, non-ferrous metal, chemical industry, burning and dust is reclaimed
On various sack cleaners, general needled filtering felt can be resistant to less than 150 DEG C of temperature, but the occasion more to flue gas, by
The deep layer of filtrate is easily cut in dust and causes resistance to rise comparatively fast, Damage, mistake are filtered in the effect of long-time superficial oxidation
Filter effect is reduced, so having higher requirement to the strainability of needled filtering felt.
The compound spiked felt of high temperature resistant, corrosion-resistant, lower resistance, is primarily directed to affect China's atmosphere quality at present
The coal-burning power plant of one of primary pollution source.Sack cleaner is the capital equipment for administering minuteness particle, and filtrate is then that pocket type is removed
The core easily-consumed products of dirt device, the expense of the annual filtrate in the whole nation is more than 3,000,000,000 yuan.
As the flue gas of coal-burning power plant is high-temperature flue gas, and the oxygen content of high-temperature flue gas is higher, and the combination of these factors is made
With the service life that can drastically reduce filtrate, it is therefore necessary to solve adverse effect of the oxygen to filtrate in high-temperature flue gas.
Utility model content
For above-mentioned produced problem, this utility model provides a kind of structure effectively, the strong PPS acupunctures of antioxygenic property
Filter felt.
A kind of resistance to oxidation PPS needled filtering felt, including basic unit, are arranged on filter layer, the bottom of basic unit's upper and lower surface, and
It is arranged on the top layer for filtering layer surface；The top layer is expanded microporous polytetra fluoroethylene-EPTEE more than a layer（ PTFE ）Thin film, with filter layer heat
Pressure is formed；The filter layer is carbon fiber layer, adds B in carbon fiber layer4C and SIC materials；The bottom is polyimide fiber
Layer；The basic unit is one or more composition in PPS fibrous layers and glass layer, PTFE fiber layer, P84 fibrous layers.
Further, the carbon fiber layer is carbon felt.
Compared with prior art, have the advantage that for：By the use of top layer of the carbon felt as filter felt made by carbon fiber,
Adding special material in carbon felt increases the toughness of resistance to oxidation and integral filter felt of material, while improving acid resistance, alkali resistance
Strong, the resistant to hydrolysis ability with corrosion resistance, strengthens material performance, and filtering accuracy is high.
Description of the drawings
Fig. 1 is this utility model resistance to oxidation PPS needled filtering felt structural representation.
Specific embodiment
A kind of embodiment of this utility model resistance to oxidation PPS needled filtering felt, including basic unit 1 are illustrated as, basic unit is arranged on
The filter layer 2 of upper and lower surface, bottom 3, and it is arranged on the top layer 4 for filtering layer surface；The top layer is micropore poly- four more than a layer
Fluorothene（ PTFE ）Thin film, is formed with filter layer hot pressing；The filter layer is carbon fiber layer, adds B in carbon fiber layer4C and
SIC materials, the carbon fiber layer are carbon felt；The bottom is polyimide fiber layer；The basic unit be PPS fibrous layers based on,
And one or more in PPS fibrous layers in addition glass layer, PTFE fiber layer, P84 fibrous layers according to actual needs
Material constitutes new base layer structure.
