Generally speaking, the working conditions of smoke and dust at the end of rotary kiln in cement plants are relatively complex, including fine dust particle size (average dust particle size 1-30μ); high humidity; high and fluctuating flue gas temperature; and dust entrance Features such as high concentration.
This places high demands on the filter bags to be selected.
As the core component of the dust collector, the filter bag is related to the effect of the entire transformation and is also a large part of the investment. Therefore, for the sake of caution, we have carefully researched and investigated the commonly used filter materials on the market. It was found that some common domestic filter materials commonly used in domestic bag dust collectors inevitably have defects such as high operating resistance, easy “hardening” of the filter materials and premature failure, and short service life.
For cement manufacturers, they are not only required to control dust emissions, but also hope to continuously increase production, reduce production energy consumption, extend the service life of filter materials, and reduce production costs.
After careful investigation and research on the market and domestic and foreign dust collector filter bags, it will be the best way to use ptfe air filter membrane-coated filter material. The filter surface of the filter material is compounded with a layer of ” The microporous and extremely smooth polytetrafluoroethylene (ptfe) film made of “expanded” patented technology is a unique “surface filtration” technology.
Because the fiber structure of the polytetrafluoroethylene (ptfe) film is extremely fine, the dust emission after the dust-containing gas passes through the filter material is close to zero, which can meet strict emission requirements in the future.
Suzhou is a manufacturer that specializes in R&D and production of PTFE air filter membranes. It has a group of professional polymer R&D teams with strong R&D capabilities and has multiple invention patent certificates and practical patent certificates.
And according to the user’s requirements, the key parameters of ptfe air filtration membrane technology such as speed ratio, pressure ratio, operating temperature, etc. can be optimized and combined. According to the ratio and pore-forming medium, the air permeability, thickness and voids can be achieved The rate can be adjusted online to meet the different requirements you need.
