Selection of Right Bag Filter For Your Industry

Many industrial processes generate dust and particles, which contaminate the air. Uncontrolled pollutants can lead to health problems for your workers, safety issues, may affect quality of your our products, and even plant-wide shutdowns. To avoid these things, you must employ a Bag Filter.

Raj Deep ENVIROCON is one of the leading manufacturers and suppliers of Bag Filter to minimize the polluting dust/particles out of the chimney. The purpose of the Bag Filter is to ensure that industrial air pollution is minimized .This system can be easily modified and customized as per the customers requirement .However, the different industrial applications will need different structures of Bag Filters.

Raj Deep ENVIROCON team can help you in knowing about which is the right kind of bag filter for your industry. Designing Bag Filter needs knowledge of types of dust, duct design, critical duct velocity, Capturing/Suction hood selection and design, chimney design, chemicals used and the temperature needed, we can suggest to our clients the type of Bag Filter they can have. This blog covers some of the insights regarding the right kind of bag filter one can have for the industrial application. The process below provides a summary of the factors that you need to be concerned with when designing a new dust collection system.

1. Equipment of Dust Generation: System design starts with finding, identifying, and mapping out the areas, equipment’s and processes in your plant that are generating dust. Also identify dust generation points which may be added in future.

Various dust generation equipments are Belt Conveyor, Crusher, Vibratory Screen, Bunker Top, Mills etc. Based on this initial inputs we can determine capacity and size of the bag filter.  It is also possible to have various modules of bag filter to manage available space and reduce to risk of air pollution emitting particles. Industrial application and processes that will decide which type of bag filter one should have.

2. Calculate Air Volume: Raj Deep ENVIROCON is one of the leading qualified companies experienced in system design and well-versed in calculating the air volumes that are required for different types of dust generating processes. Calculating air volume is critical to properly designing your dust collection system, as insufficient air volume will cause inadequate dust collection. Raj Deep ENVIROCON ensures and practices design manual available from The American Conference of Governmental Industrial Hygienists (ACGIH).

3. Ducting Design : Ductwork is essential to convey captured dust from source point to Bag Filter inlet. Depending on CFM at each branch of the system size of duct is calculated. Choosing the right location of your Bag Filter will be influenced by factors such as collector size, particulate characteristics, how particulates will be handled during final disposal, and maintenance accessibility. Due to friction, each foot of duct and each elbow will require more energy. Your system must be able to overcome this friction. Lowering system static pressure will ultimately lead to more efficient, and less costly, design.

4. Fabric for filter bags :The chemical resistance and the temperature are the most determining factors for deciding upon the fabric type. Usually, four basic kinds of fabrics go into making bag filters. They are polypropylene, polyester, Nylon, and Nomex. One can use other kinds of fabrics too but, then they are used in case of some special applications only.

5. Polypropylene : They are most commonly used because cost-friendly and have excellent chemical resistivity. It can withstand temperature up to 200oF which is great and therefore it supports many application types

6. Selection of the Exhaust Fan : The next consideration for your dust collector design is the exhaust fan. This is what’s used to take the dust-laden air from your collection points, through all your ductwork, and finally through your Bag Filter itself. You need to properly size your fan to generate the desired air flow at the previously calculated static pressure. Selecting the correct exhaust fan/motor combination will ensure your system delivers the design air volume.

7. Auxiliary Equipment : To have the most efficient dust collector, you’ll need to consider how dust will be discharged from your hopper. Remember, it’s not just about removing particulates from your system, but also disposing of them in a proper manner. Auxiliary equipment such as rotary valves, slide gates, drum filling attachments, and screw conveyor is used in conjunction with the critical pieces of your dust collector for an overall more efficient design.
