Sleeve Filter

More and more we talk about environmental pollution, environmental problems and global warming. One of the reasons that these problems are exacerbated, the industry, more emissions are allocated to factories. At this each time the plant has the exact maximum level of emissions that it can release into the atmosphere if the emissions do not meet the requirements, followed by fines and sanctions. To capture harmful and / or unnecessary dust installed filters, and very often this bag filters. Bag filters can be used for two purposes: 1) to prevent ingress of atmospheric emissions of the production process and 2) the collection of products and return it back into production. It was in these filtration systems, such as filter elements, filter bags installed.

Sleeve filter may have different sizes (diameter and length), different arrangements for strengthening them in the filter, and their various modifications are dictated by what a regeneration system is applied in a particular installation. For example, in systems with impulse blowing (the surface of the sleeves brush away from nozzle dust momentum of air), typically used for hose frame basis with a weight of 500-600 g/m2, which makes the sleeve extra strength and durability. In the Shakers used the sleeves of the materials of 350-400 g/m2 because of flexibility. It is also lighter and more flexible materials used in the sleeves for systems with backflushing, their weight is usually in the borders of 400-500 g/m2. What materials are used in the manufacture of filter bags? Usually it is woven punched material from various synthetic fibers. The choice of fiber is determined by the environment and the process temperature. For example, for dry environments where the temperature neprivyshaet about 140 degrees Celsius, are used sleeve of nonwoven webs of polyester fibers.

On the other hand, if the environment is very acidic and the temperature reaches 270 degrees Celsius the only thing that fits, it's the sleeve of polytetrafluoroethylene. Also differ and the ways longitudinal joint sleeves. Most-seam stitching way but also can use the method of heat sealing. Heat seal is only possible if the sleeve of a material which melts at certain temperature (polyimide and polytetrafluoroethylene welding is impossible). There are many manufacturers of filter bags but only some of them are knowledgeable and experienced producers. For best kachnstva vyberat checked bags. More details on the sleeves and species you can find on the website Andrew Webron Limited, which is a manufacturer of nonwoven fabrics and filter bags.
