Frequently Asked Questions (FAQs)
1. What is the process of bag filter?
The process of a bag filter involves the dust layer adhering to and being deposited on the surface of the filter bag and the interior of the filter cloth. This primary dust layer filters and collects the dust present in the process gas. The fabric of the filter bag provides a surface for dust particles to accumulate and get trapped.
2. What are the different types of bag filters?
There are four types of bag filters based on the shape of the filter bag: circular bag filter, flat bag filter, double-layer bag filter, and diamond bag filter. The external bag filters have a diameter of φ120mm-160mm, while the internal bag filters have a diameter of φ200mm-300mm or larger.
3. What material are filter bags made of?
Filter bags are made from various materials, including nylon, polypropylene, polyester, porous PTFE film, fluoropolymers, viscose, aromatic polyamides, felts, and woven wool. These materials offer different filtration ratings, ranging from 1 to 1200 µm, depending on the specific application and requirements.
4. How often do you change an industrial air filter?
In an industrial facility or plant, it is generally recommended to change or clean the air filter once a week. However, the frequency may vary depending on the specific conditions and the type of air filter used. Industrial spaces may require stronger air filters compared to other environments to effectively capture and remove contaminants.
5. How often should bag filters be changed?
The frequency of changing bag filters depends on various factors. In general, baghouse filters have a useful life of 1-3 years. However, the actual lifespan can vary based on factors such as the type of process, the nature of the dust being filtered, operating conditions, and maintenance practices. Regular monitoring and inspection of the filter bags are necessary to determine when they need to be replaced.
6. What is the best fabric for filter bags?
There are several fabric options available for filter bags, including cotton (woven), polyester, high-efficiency felts, polypropylene, nylon, acrylic, aramid, and fiberglass. The choice of fabric depends on factors such as operating temperature, efficiency requirements, chemical compatibility, and durability. Each fabric has its advantages and is suitable for specific applications and operating conditions.
