CEMENT INDUSTRY
Yanpai Co., Ltd. has cultivated earlier in the cement industry and has a more complete product chain; all kinds of filter materials such as normal temperature, high temperature, chemical fiber, glass fiber are readily available; at the same time, Yanpai is also the best domestic manufacturer of breathable layer cloth; its advantageous products There are MX, PI, GL-11, etc.
Yan brand unique – breathable layer cloth: the breathable layer cloth is suitable for the air chute of the cement plant grinding station, the air box homogenization storehouse cement pneumatic conveying, and the homogenization storehouse. It is an indispensable accessory product in the cement industry.
Cement mill dust removal:
Cement mill dust removal is divided into raw meal mill and clinker mill. Under the original emission standard, PE550 grams of conventional filter material is basically used, which is oil-proof and waterproof.
Imported flue gas dust concentration: usually ≤ 300g/m3
Flue gas temperature: less than 120 ℃
Filter solution: for ≤10mg/Nm3 ultra-low emission transformation, push
The recommended filter material is PE ultra-fine blended surface layer 550g filter material, oil-proof, anti-oil
Water treatment; it is recommended that the filtration wind speed be less than 0.75m/min.
Coal mill dust removal:
At present, in the new dry process cement production line, the original PE 550 gram conventional filter material is basically used, with anti-static, oil-proof and waterproof treatment;
Coal mill exhaust gas temperature: generally 60 ~ 80 ℃
Flue gas pulverized coal concentration: generally can reach 600~800g/m3
Particle size: less than 10μm accounts for 40%~80%
Filter material scheme: for ≤ 10 mg / N m 3 ultra-low emission transformation, recommended
The filter material is PE ultra-fine blended surface layer 550g filter material, 550g film coating, anti-static, oil-proof, waterproof treatment; it is recommended that the filtration wind speed be less than 0.75m/min;
Kiln head and kiln tail dust removal:
kiln head
Temperature: 150 ℃~200 ℃
Dust concentration: ≤30g/Nm3
Recommended filter media: MX550g filter media, PI+MX composite filter media;
Filtering wind speed: ≤ 0.75m/min;
Kiln tail
Temperature: 200~240℃, 150-180℃ after waste heat power generation
Dust concentration: ≤100g/Nm3
Filter material recommendation: PI/TF550g filter material, PI+MX composite filter material, glass fiber coating;
