Product Description
A bag filter housing is a type of filtration system used to hold and support filter bags in various liquid filtration applications It is designed to remove contaminants and particles from liquids flowing through industrial processes Heres an overview of bag filter housings including their construction operation applications and considerations
Construction and Design
Material Bag filter housings are typically constructed from materials such as stainless steel carbon steel or plastic like polypropylene depending on the compatibility with the fluid being filtered and the operating conditions
Housing Configuration
Single Bag Housing Designed to hold a single filter bag for smaller flow rates and applications
MultiBag Housing Configured to accommodate multiple filter bags commonly 2 to 24 bags within a single housing unit for higher flow rates and larger filtration capacities
Inlet and Outlet
Top Entry Many bag filter housings have a top entry design where the liquid enters from the top and flows downward through the filter bags
Side Entry Some housings feature a side entry where the liquid enters from the side and flows through the filter bags horizontally
Closure Mechanism
Bag filter housings typically have a hinged lid or bolted closure mechanism to securely seal the housing during operation and prevent leakage
Operation
Filtration Process
The liquid enters the bag filter housing and flows through the filter bags
Contaminants and particles larger than the filter bags micron rating are captured within the filter bag
Cleaned liquid exits through the outlet while the trapped particles remain inside the filter bags
Bag Replacement
Bag filter housings are designed for easy bag replacement The filter bags can be quickly removed and replaced during maintenance or when the filtration efficiency decreases
Key Features and Benefits
1 Versatility Bag filter housings are used in a wide range of industries including chemical processing pharmaceuticals food and beverage water treatment oil and gas and more
2 Flexibility They accommodate various types of filter bags made from materials such as polypropylene polyester nylon or specialty materials for specific applications
3 High Flow Rates Multibag filter housings can handle high flow rates and large volumes of liquid making them suitable for industrialscale filtration
4 Efficiency Bag filters effectively capture contaminants and particles down to submicron levels depending on the micron rating of the filter bags used
5 Ease of Maintenance Designed for easy access and bag replacement minimizing downtime and labor costs associated with maintenance
Applications
Water Treatment Municipal water treatment plants industrial water filtration systems and process water filtration
Chemical Processing Filtering chemical solutions acids bases and solvents to remove impurities
Oil and Gas Filtration of crude oil natural gas and refined products to remove particulates and contaminants
Food and Beverage Filtration of beverages edible oils syrups and other liquid food products
Considerations
Micron Rating Choose filter bags with an appropriate micron rating based on the particle size to be removed and the desired filtration efficiency
Material Compatibility Ensure the filter housing and filter bags are compatible with the type of liquid and chemicals being processed to prevent corrosion or degradation
Flow Rate and Capacity Select a housing size and configuration single or multibag that matches the flow rate and filtration capacity required for your application
Regulatory Compliance Ensure that the bag filter housing meets regulatory standards and requirements applicable to your industry and application
Summary
Bag filter housings are versatile and efficient filtration systems used in various industries to remove contaminants and particles from liquids Their robust construction ease of maintenance and compatibility with different filter media make them essential components in maintaining product quality and process efficiency across a wide range of industrial applications
