Bionomic - Baghouse Dust Collector

Filter Bags and Design Considerations

A fabric filter bag typically has a diameter of 4.5” or 6” with lengths of 36″, 60″, 72″, 96″, 120″ or 144″. The size of a Baghouse Dust Collector varies widely, ranging from only a single bag to having thousands of bags.

Based on the specific application, Bionomic Industries optimizes baghouse design details such as air-to-cloth ratio, filtration velocity, filter area, interstitial velocity, can velocity, filter type, and housing size. Each design is customized to the unique needs of the operation processes and dust properties.

Our top priority is to supply a high-quality dust collector that you can rely on. Whether you require a collector to accommodate high temperature, high pressure, corrosive and/or moisturized gases, explosive dust, hygroscopic dust or other harsh conditions, Bionomic Industries can provide a reliable and safe solution.

Modular Baghouse Dust Collectors

Bionomic Industries’ modular baghouse systems can accommodate high gas flow rates greater than a million cubic feet per minute. Redundant designs allow separate modules to be cleaned off-line while others continue filtration operations. Redundant systems offer increased flexibility, bag life, and cleaning efficiency.

Types of Baghouse Cleaning Systems

Baghouses are by far the most common type of air pollution control equipment. Baghouse dust collectors include built-in filter cleaning systems that prevent the filter bags from plugging.

Baghouses are generally classified by the systems of bag cleaning. There are three common types:

• Pulse Jet
• Reverse Air
• Shaker

Pulse jet baghouse systems are the most common type. High-pressure compressed air is used for cleaning the filters. Pulse jet systems offer the advantage of consistency in dust removal efficiency.

Reverse air baghouse systems clean the filters with high-volume and low-pressure reverse flow air.

Shaker style baghouse systems utilize a motor-driven mechanical system to clean the filters by shaking them. This occurs while off-line, without any inlet dust-laden gas.

Pre-Filters Ahead of a Baghouse

One of the following pre-filters is normally installed ahead of a baghouse when dust loading is higher than 5 grains/ft3:

• Low efficiency cyclone
• Dropout box
• Settling chamber

Bionomic Industries can recommend & design the system prefilter based on the application and user preferences.

Baghouse Dust Collection Services

Bionomic also provides the following services to ensure you operate a worry-free baghouse dust collection system:

• A complete range of baghouse parts
• Preventative maintenance
• Installation supervision, start-up and commissioning services
• Training seminars and/or webinars
• Baghouse conversions and upgrades

Preventative Maintenance Services

• Change-out of filter bags, and replacement of seals and gaskets
• Verifying functionality and operation of all solenoid valves, diaphragm valves, instrumentation, controls, and hopper discharge system
• Field measurement and documentation of system parameters:
• Differential pressure
• Gas flow rate
• Temperature, static pressure, velocity pressure, humidity ratio
• Ventilation system balancing / air balancing
• Diagnostic analysis of dust collection systems
• Conditions of the metal structure of the baghouse dust collection system in terms of corrosion and erosion wear
• Comparing the measured data with design parameters and resolving discrepancies
• Modes and conditions under which the baghouse dust collection system was operated
• Baghouse dust collector maintenance training

Baghouse Conversions and Upgrades

Baghouse dust collectors can often be re-built or upgraded at a fraction of the cost of a new collector. The collection efficiency of outdated reverse air and shaker designs can also be improved with pulse jet cleaning, typically increasing the amount of gas volume the collector can clean without increasing the collector size.
