Abstract
The invention discloses a stiffening filter material structure for a high-temperature-resistant filter drum. A hardened layer is formed on the fiber surface of a base filter material by virtue of cross-linking solidity with a high-temperature-resistant stiffening agent; the high-temperature-resistant stiffening agent subjected to cross-linking solidity is wrapped by a continuous hardened sheath shell on the fiber surface, the crossing parts of the fibers are connected to form nodes; the high-temperature-resistant stiffening agent forms a three-dimensional framework is integrally formed on the filter material based on fibers; the filter material can keep stiffness at high temperature and still can maintain high porosity so that the filter material has lower resistance, and thus the shortcomings and deficiencies that in the prior art, pores of the filter material are blocked by glue to cause the reduction of the porosity of the filter material to influence filtration performance are overcome.
Description
Technical field
The invention relates to a kind of filter cylinder filter structure, refer to the stiffening filter structure of a kind of high-temperature-resistant filter cylinder especially.
Background technology
Filter cartridge dust remover is owing to having less equipment volume, and larger filter area, has been widely used in the clarifying smoke of multiple industry.Current low temperature filter cylinder is as ripe in terylene filter cylinder, but high temperature filter cylinder is comparatively rare.Current filter cylinder base material filtrate method adopts the filtrate with stiffness of spun-bond process, melt-blown legal system, or adopts glue to carry out stiffening process to filtrate.Publication number is that the Chinese invention patent application of CN102166455A discloses a kind of high-temperature resisting stiffened needled felt, namely adopts glue to carry out stiffening process.This series products all has stiffening effect at normal temperatures, but at high temperature will soften due to most of macromolecular material, the filter cylinder made with this will lose deflection at service temperatures, and filter cylinder in use will cause distortion because filtering-jetting, and which has limited the application of filter cylinder at high-temperature field.Publication number is that the Chinese invention patent application of CN201399287A discloses a kind of high-temperature resisting stiffened needled felt, namely sclerosis permeable formation is pasted in Nomex upper and lower surface, the hole of filtrate will block by glue, affect the gas permeability of product, and filter cylinder will be caused to lose efficacy because of plication region cracking when being processed into filter cylinder.Therefore, suitable high-temperature-resistant filter cylinder is developed most important in the application of high-temperature field for filter cylinder with stiffening filtrate.
Summary of the invention
The object of the invention is to provide a kind of high-temperature-resistant filter cylinder of effective guarantee filtrate porosity stiffening filter structure.
For achieving the above object, solution of the present invention is:
The stiffening filter structure of a kind of high-temperature-resistant filter cylinder, utilizes high temperature resistant stiffening agent at fiber surface crosslinking curing one deck hardened layer of filter material substrate.
Described high temperature resistant stiffening agent is fire resistant resin.
Described fire resistant resin is machine silicones, polyimides or polysulfone resin.
Described filter cylinder base material is polyphenylene sulfide, aramid fiber, polyimides, the non-woven fabrics that one or more the above fibers in polytetrafluoroethylene (PTFE) or glass are made into or woven fabric.
After adopting such scheme, high temperature resistant stiffening agent after crosslinking curing is surrounded by one deck continuous print sclerosis sheath shell at fiber, and couple together formation node at fiber intersection, do not changing on filtrate original structure, high temperature resistant stiffening agent relies on fiber to form " bone " of 3 D stereo in filtrate entirety, filtrate at high temperature can keep deflection, and filtrate still can keep high porosity, the stiffening filtrate of order has lower resistance, thus the hole overcoming prior art filtrate is blocked by glue, cause filtrate porosity to decline, affect the shortcoming and defect of strainability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the test of filter cylinder base material filtering material resistance.
Detailed description of the invention
As shown in Figure 1, present invention is disclosed the stiffening filter structure of a kind of high-temperature-resistant filter cylinder, utilize high temperature resistant stiffening agent at fiber 1 surface-crosslinked solidification one deck hardened layer 2 of filter material substrate.The described high temperature resistant serviceability temperature referring to base material filtrate, usually at 130 DEG C-280 DEG C.Described high temperature resistant stiffening agent main component is fire resistant resin, including, but not limited to organic siliconresin, and polyimides, polysulfone resin etc.Described filter cylinder base material filtrate refers to polyphenylene sulfide, aramid fiber, polyimides, polytetrafluoroethylene (PTFE), the non-woven fabrics that one or more the above fibers in glass are made into or woven fabric.
High temperature resistant stiffening agent after crosslinking curing is surrounded by one deck continuous print sclerosis sheath shell at fiber 1, and fiber intersection couple together formed node 3, do not changing on filtrate original structure, high temperature resistant stiffening agent relies on fiber 1 to form " bone " of 3 D stereo in filtrate entirety.
Embodiment 1
Organic siliconresin aqueous solution is adopted to carry out stiffeningization process on polyphenylene sulfide water thorn felt.
Table 1. is polyphenylene sulfide spunlace non-woven cloth felt performance comparison before and after organosilicon stiffeningization
Embodiment 2
Polyimide resin dispersion liquid is adopted by aramid spunlace felt to carry out stiffeningization process.
Table 2. is aramid spunlace nonwoven felt performance comparison before and after polyimides stiffeningization
Embodiment 3
Polysulfone resin dispersion liquid is adopted to carry out stiffeningization process on polyphenylene sulfide water thorn felt.
Table 3. is polyphenylene sulfide spunlace non-woven cloth felt performance comparison before and after polysulfones stiffeningization
As can be seen here, filtrate of the present invention at high temperature can keep deflection, and filtrate still can keep high porosity, the stiffening filtrate of order has lower resistance, thus the hole overcoming prior art filtrate is blocked by glue, cause filtrate porosity to decline, affect the shortcoming and defect of strainability.
