Bag Filter Housing

A bag filter housing is a device used to support and contain filter bags that remove particles from liquids or gases. It consists of a housing shell, inlet and outlet ports, a bag support basket, filter bags, seals, and valves. The fluid flows through the bag, which captures contaminants, while the filtered fluid exits the housing. There are single-bag and multi-bag options depending on flow rate. Common applications include water treatment, chemical processing, and air filtration. Bag filter housings are efficient, easy to maintain, and versatile for various industries.
Key Components of Bag Filter Housing:
Housing Shell: The main body or casing of the bag filter housing, typically made of materials like stainless steel, carbon steel, or plastic, depending on the nature of the fluid being filtered and the working conditions.
Inlet and Outlet Ports: These allow the fluid to enter and exit the housing. They are often designed with flanges for easy connection to pipes or systems.
Bag Support Basket: A metal or plastic frame inside the housing that supports the filtration bag, ensuring it stays in place while filtering.
Filter Bag: A fabric bag that captures contaminants from the fluid as it flows through. The bags come in various sizes and materials, such as polyester, nylon, or polypropylene, depending on the specific application.
Seals and Gaskets: Ensure that the housing is tightly sealed to prevent leaks during filtration. These seals are usually made of rubber, silicone, or other materials resistant to the fluid being filtered.
Drain Valve: Located at the bottom of the housing, this valve is used to empty or discharge any collected contaminants or filtrate.
Pressure Relief or Vent Valve: Prevents the buildup of excessive pressure inside the housing by allowing safe release of pressure if needed.
