Abstract
A special novel composite filter material for a cement rotary kiln rear relates to a composite material, and comprises a P84 fineness fiber layer, a glass fiber and polysulfonamide fiber combined layer, a PTFE (polytetrafluoroethylene) fiber base cloth layer and a P84 fineness fiber, glass fiber and polysulfonamide fiber combined layer. The glass fiber and polysulfonamide fiber combined layer is arranged on the inner side of the P84 fineness fiber layer, the PTFE fiber base cloth layer is arranged on the inner side of the glass fiber and polysulfonamide fiber combined layer, the glass fiber and polysulfonamide fiber combined layer is arranged on the inner side of the PTFE fiber base cloth layer, and a dust facing surface is coated with PTFE liquor. The composite filter material has the advantages that acid and alkali resistance, hydrophobicity and oxidation resistance of fibers are greatly enhanced, cohesive force of the fibers is increased, the strength and surface abrasiveness of a felt are enhanced, suppleness of glass fibers is further improved, folding endurance is higher, and the composite filter material is shaped by heating and treated by calendering so that the service life of the felt is prolonged.
Description
Technical field:
The utility model relates to a kind of composite filtering material, is specifically related to a kind of novel concrete rotary kiln kiln tail specific composite filter material.
Background technology:
At present, the filtrate industry is all actively being inquired into and research and development with filtrate at the deduster in cement plant, major subjects is that the practicality of product is a high efficiency, lower resistance, corrosion-resistant, high temperature resistant, low-cost, extensively Shi Yong product is the P84 filtrate, 240 ℃ of its heatproofs, alkali resistance is general, finished product price height, aramid fiber filtrate, its heatproof degree only is 204 ℃, neither be enough to, be difficult to reach the desirable requirement of enterprise, and cost be excessive, the work condition environment of rotary cement kiln kiln tail is comparatively complicated, nitric oxide wherein, the extremely strong pernicious gas of corrosivity such as sulfur dioxide and fluoride to filtrate produce very harmful, cause filtrate intensity and descend, damaged, all increase for the maintenance and the cost input of enterprise greatly, thus cement industry be badly in need of a kind of practical, lower-cost novel product.
The utility model content:
The purpose of this utility model provides novel concrete rotary kiln kiln tail specific composite filter material, it has improved the anti acid alkali performance of fiber greatly, hydrophobicity, oxidation resistance, the cohesive force of increase fiber, the intensity and the surface abrasion resistance of felt body have been promoted, but also having improved the pliability of central glass, folding resistance is stronger, through thermal finalization, calendering is handled, the service life of having improved the felt body.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of P84 fineness fibrage 1, glass fibre and polysulphonamide fiber combination layer 2, PTFE fiber base layer of cloth 3 and P84 fineness fiber, glass fibre and polysulphonamide fiber combination layer 4; Glass fibre and polysulphonamide fiber combination layer 2 are arranged on the inboard of P84 fineness fibrage 1, PTFE fiber base layer of cloth 3 is arranged on the inboard of glass fibre and polysulphonamide fiber combination layer 2, glass fibre and polysulphonamide fiber combination layer 4 are arranged on the inboard of PTFE fiber base layer of cloth 3, under the impregnation process of PTFE admixing medical solutions, make the felt surface adhere to a skim through felt body that acupuncture is made.
The utlity model has following beneficial effect: the anti acid alkali performance that has improved fiber greatly, hydrophobicity, oxidation resistance, increase the cohesive force of fiber, promoted the intensity and the surface abrasion resistance of felt body, but also improved the pliability of central glass, folding resistance is stronger, through thermal finalization, calendering is handled, the service life of having improved the felt body.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment by the following technical solutions: it is made up of P84 fineness fibrage 1, glass fibre and polysulphonamide fiber combination layer 2, PTFE fiber base layer of cloth 3 and P84 fineness fiber, glass fibre and polysulphonamide fiber combination layer 4; Glass fibre and polysulphonamide fiber combination layer 2 are arranged on the inboard of P84 fineness fibrage 1, PTFE fiber base layer of cloth 3 is arranged on the inboard of glass fibre and polysulphonamide fiber combination layer 2, glass fibre and polysulphonamide fiber combination layer 4 are arranged on the inboard of PTFE fiber base layer of cloth 3, and dust-collecting face is with PTFE soup coating.
The recipe ratio of described glass fibre and polysulphonamide fiber combination layer 2 is glass fibre 60%, polysulphonamide fiber 40%.
P84 fineness fiber, glass fibre and polysulphonamide fiber respectively account for the above three-D space structure of 1/3rd compositions and form a close packing gradient in described P84 fineness fiber, glass fibre and the polysulphonamide fiber combination layer 4, form a beloid filtering layer passage, to filter the dirt operation and concentrate on filter material surface significantly, alleviated the pressure of the inner filter of filtrate dirt, make the filtrate internal layer be difficult for control of dust, this structure, dust is detained the surface and is easy to deashing, helps the central deduster running resistance of work to reduce and keeps stable.
This specific embodiment technological process of production is:
This specific embodiment has improved the anti acid alkali performance of fiber greatly, hydrophobicity, oxidation resistance, increase the cohesive force of fiber, promoted the intensity and the surface abrasion resistance of felt body, but also improved the pliability of central glass, folding resistance is stronger, through thermal finalization, calendering is handled, the service life of having improved the felt body.
