Abstract
The invention discloses a special felt for kiln tail of dry rotary kiln cement production, and relates to the technical field of filter material. The special felt comprises PTFE base fiber, composite layers containing PTFE fiber and Kermel fiber, and a composite layer containing pretreatment ultra-fine glass fiber and PTFE fiber. Two sides of the PTFE base fiber are respectively provided with the composite layer containing PTFE fiber and Kermel fiber; and the layers and the base fiber are combined through a needling process. The composite layer containing PTFE fiber and Kermel fiber, on a direction from which the filtration gas enters, is provided with the composite layer containing pretreatment ultra-fine glass fiber and PTFE fiber. The special felt has structure unaffected by the needling rolling process, and superior water resistance.
Description
Technical field
The present invention relates to the filtrate technical field, be specifically related to a kind of dry-process rotary kilns and produce the special-purpose felt of kiln tail.
Background technology
Because the environment steam of dry-process rotary kilns kiln tail is large, gas attack is strong and gas temperature is high, dust granules is tiny, the kiln tail is expensive with pure P84 cloth bag, and raw material is affected by import, can not large-scale promotion application, and easily be hydrolyzed in the composite felt filtering media application process of the existing glass fibre that uses and P84, loss is fast; And destroyed the institutional framework of filtrate in the composite felt filtrate acupuncture operation of rolling of glass fibre and P84, made filtrate have certain potential safety hazard before being applied to equipment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of institutional framework and is not subjected to that acupuncture is rolling to be affected, and the superior dry-process rotary kilns of water resistance are produced the special-purpose felt of kiln tail.
In order to realize the foregoing invention purpose, following technical scheme is adopted in the invention:
A kind of dry-process rotary kilns are produced the special-purpose felt of kiln tail, comprise PTFE base fibre, PTFE fiber and Ke Maier fiber composite layer and pre-treatment superfine glass fiber and PTFE fiber composite layer, PTFE fiber and Ke Maier fiber composite layer are laid respectively in the fine both sides of PTFE base, specifically by the needling process combination; The PTFE fiber of filtering gas approach axis and Ke Maier fiber composite layer are provided with pre-treatment superfine glass fiber and PTFE fiber composite layer.
Owing to adopting technical scheme as above, the invention produces following good effect:
1, due to the selection of the special-purpose felt filter material of kiln tail material, compound use by several fibers, the characteristics of every kind of fiber are effectively brought into play, and mutually complement, make it pliability, the performances such as temperature tolerance, corrosion resistance, resistance to water improve, and cost is low, cost performance is high, more can well adapt to the production environment of kiln tail.
2, the special-purpose felt filter material of kiln tail material, because base cloth adopts the PTFE base cloth, make it not to be subjected to needling process to affect, thereby do not affect the application of special-purpose felt.
Description of drawings
Fig. 1 is the structural representation of the special-purpose felt cross section of kiln tail of the invention;
The specific embodiment
In conjunction with Fig. 1, the dry-process rotary kilns of the present embodiment are produced the special-purpose felt of kiln tail, comprise PTFE base fibre, PTFE fiber and Ke Maier fiber composite layer and pre-treatment superfine glass fiber and PTFE fiber composite layer, PTFE fiber and Ke Maier fiber composite layer are laid respectively in the fine both sides of PTFE base, and the PTFE fiber of filtering gas approach axis and Ke Maier fiber composite layer are provided with pre-treatment superfine glass fiber and PTFE fiber composite layer.
Select PTFE to do base cloth, PTFE is commonly called as omnipotent King, has formed the body strong as iron of cloth bag, has guaranteed the good result of use of cloth bag.
PTFE fiber and Ke Maier fiber composite layer replace P84, when guaranteeing result of use, have reduced use cost, and its product cost performance is significantly improved.
By using pre-treatment superfine glass fiber and PTFE fiber composite layer, guarantee to have improved the corrosion resistance of product under the prerequisite of filtering accuracy at ultra-fine layer.
