Common faults and cause analysis of the bag filter-the resistance increases beyond the normal value, and the resistance cannot be reduced after the dust removal operation
Aug 20 , 2021
Cause Analysis: (1) Pouch paste phenomenon occurs. (2) The ash cleaning device fails, and there is no ash cleaning effect. (3) The cleaning effect is not good. (4) The filtration rate is too high. Approach: (1) When handling paste bag filter bags, use oil-proof, anti-static, and waterproof filter cloth, and adopt heat preservation measures to avoid condensation and cause paste bags. It is also pos...

Filter selection monitoring
Aug 27 , 2021
The core of the bag filter is the dust filter bag. The efficiency of the filter bag is related to the level of emission. The resistance of the filter bag affects the energy consumption of the system, and the life of the filter bag affects the reliability of the system, that is, the trouble-free operation time. The efficiency, resistance and life of the filter material are directly related to the p...

What are non-woven fabrics?
Sep 10 , 2021
Non-woven fabrics are textile structures where a consistent fibrous web is bound together through chemical/adhesive bonding or by interlocking of fibers. Non-woven fabrics are designed for many filtration applications. New constructions for specialty applications are the order of the day to address many niche filtration applications. NEEDLE PUNCHED / FELT NON-WOVEN FABRICS IN FILTRATION. Non Woven...

How to choose baghouse filter bags for cement plants？
Sep 22 , 2021
The long-term operating temperature of Yuanchen Technology's polyester industrial dust collector filter bags in dry gas should be less than 120℃, but in high-moisture flue gas, its long-term operating temperature can only drop to 60-100℃. Therefore, the selection of industrial air dust filter sleeves in cement plants should consider several factors: gas tempera...

High temperature dust collection
Sep 23 , 2021
One of the most common concerns in the history of bag filters is their ability to handle very high temperature dust gases, which is one of the reasons why electrostatic precipitators have become so popular in power plants, cement plants and other industries. In addition, it is more concerned that high-wear dust is likely to cause premature damage to the filter element (this problem is rarely found...

How To Extend The Service Life Of Filter Bags？
Oct 15 , 2021
1. Install the dust filter bag correctly and keep a reasonable gap between the dust filter bag and the cage. 2. Thicken the parts of the filter bag where the friction is greater. 4. Control the wind speed of the filtered gas to be moderate. 5. Control the temperature of the filtered gas to be moderate. 6. Choose the appropriate filter bag material and process.

INSTRUCTIONS OF PTFE MEMBRANE FIBERGLASS FILTER BAG
Oct 22 , 2021
• Bag Sewing. • The shrinkage should be considered according to both working temperature and filter media. • Use the correct thread to match the fabric - eg., homopolymer fabric and sewn with homopolymer thread, so thread lasts as fabric in the same environment. • The fiberglass filter bag circumference must be 10-15 mm longer than the cage circumference. • The filter Bag length must be 20-30 mm l...

what is the bag filter?
Oct 25 , 2021
The bag filter is a dry filter device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric. When the dust-containing gas enters the bag filter, the dust with large particles and heavy specificity will be affected by gravity. The effect settles do...
