When it comes to filtration, industrial filter bags are a crucial component of any process. Chemical attack and filtration quality are paramount, so using the right kind of filtering sleeve is essential. Below are some of the critical features to look for when purchasing filtering sleeves:
Quality of filtering sleeves
The filtering sleeves in industrial bag filters are crucial in air filtration, but what are these filters? Filtering sleeves are the most critical component of these bags, as they undergo enormous wear and tear during cleaning. Therefore, a high-quality filtering sleeve must be durable and sturdy and not have a deformed shape, which could lead to frequent replacement of the bag. In India, bag manufacturers can provide you with top-quality filters. Bag filters are often used in food and forage processing, transport, and chemical industries.
The fabric used in industrial bag filtersVA has to meet specific standards to prevent contaminants from passing through. In addition to quality, it must be resistant to certain chemicals. The most common chemicals passing through a tissue felt filter bag are mineral acids, alkaline products, and synthetic solvents. Tissue felt bags are incredibly resistant to these chemicals. They can even withstand microelectronic materials. A wide variety of textiles is used to manufacture industrial filter bags.
Proper fit
Many factors influence the life and performance of industrial filter bags. Proper fabric selection, installation, maintenance, temperature regulation, and moisture control all affect the life of a bag. Many collectors are equipped with all filament polyester twill weave fabric bags designed to improve dust release while decreasing particle retention and energy consumption. While these features are necessary for efficient filtration, the increased cost of filament yarns outweighs the risen life of a bag.
If the baghouse manufacturer is concerned with efficiency, they provide solutions. For example, polyester filter bags have a higher specific weight than polypropylene; Nylon and Nomex are used for high-temperature applications. Other materials are available, such as acrylic or silicone for dust collectors. Manufacturers of industrial filter bags understand the importance of choosing suitable fabrics for different industries.
Chemical attacks
A baghouse filter can fail for various reasons, including chemical attacks or the wrong filter fabric. Choosing the suitable filter fabric and treatment/finish depends on the characteristics of the gas stream being treated. The chemicals in the gas stream can undergo sudden changes, including a drop in operating temperature below the dew point. In these cases, chemicals condense on the filters and can cause damage to the baghouse. The proper selection of filter fabric and treatment/finish can help to reduce the risk of chemical attack and extend the life of the baghouse filters.
The rotary kiln process requires a cyclone preheater to remove moisture from the raw meal and exhaust gases. This results in intense material exchange, weakening polyester fibers. Chemical attacks on downstream filter bags can occur, and a PPS filter bag is viable.
Water treatment
Filter bags are used in water treatment facilities to remove particles and contaminants that cause contamination. They help maintain product quality and minimize process downtime, thereby limiting the risks of worker exposure to water-containing pollutants. Filter bags come in standard industry sizes and are rated according to their micron capacity. Lower micron numbers mean the filter bags can remove particles of a more acceptable length. The main uses of these filter bags are water treatment, beverage production, and the manufacturing of industrial coatings and inks.
Filter bags are commonly made of polypropylene, polyester, and nylon felt. In addition, some bags are made of PTFE or polypropylene monofilament mesh. Various chemical and thermal resistance data determine the media that should be used in industrial water treatment processes. While industrial filter bags are considered coarse filtration when no finer filtration is required, the market has driven manufacturers to develop newer and more advanced products to meet the needs of water treatment facilities. Today, filter bags are available in high-tech precision filtration that achieves up to one-micron efficiencies.
