Filter Dust with Chity
Baghouse Dust Collector
Based on size, Baghouse Dust Collectors can be categorized into single-unit dust collectors and modular or combined units to accommodate various airflow volumes.
According to the cleaning method, they are classified into pulse jet dust collectors, reverse air (rotary back-blow) dust collectors, and mechanical shaking dust collectors. Each type is designed for specific operational needs and dust characteristics.
A special application is the silo top dust collector, designed to control dust emissions during material storage and conveying.

A rotary back-blowing dust collector is an industrial filtration system that uses a rotating mechanism to clean filter elements with reverse airflow.
A round pulse jet dust collector is a filtration system with cylindrical filters and a pulse jet cleaning mechanism to efficiently remove dust and maintain air quality.
Shaker dust collector is a self-cleaning filtration system that removes airborne dust by shaking its filter bags to dislodge accumulated particles.
Multiple sets of baghouse dust collectors can be combined to form a large-scale industrial dust collector, ideal for handling high-volume industrial flue gas.
How to Choose the Right Baghouse for Your Industry?
Selecting the right dust collector is critical for ensuring effective air pollution control, equipment longevity, and compliance with environmental regulations. The following steps outline a professional approach to choosing the most suitable dust collector for your application:
1. Identify the Application Scenario
The first step is to determine the working conditions and dust characteristics. For light dust or fine particulate matter, such as welding fumes or polishing dust, a cartridge dust collector is typically sufficient. In heavy-duty industries or environments with high dust concentrations, a Baghouse Dust Collector is more appropriate due to its larger capacity and superior filtration performance.
2. Determine the Required Airflow (CFM)
Analyze the dust-generating equipment or the source of flue gas to calculate the required airflow. For example, a 2-ton coal-fired boiler and a 20-ton boiler will have significantly different air volume requirements. Accurate estimation of airflow is essential to ensure proper dust collection without system overload.
3. Select the Appropriate Filtration Velocity
The filtration velocity (air-to-cloth ratio) greatly affects dust removal efficiency. Lower velocities (e.g., 1 m/min) yield better filtration and lower emissions, while higher velocities (e.g., 2 m/min) may be acceptable for less stringent applications. The choice depends on the required emission standards and filtration performance.
4. Consider Gas Temperature and Corrosiveness
Evaluate the temperature and chemical composition of the gas stream. These factors influence the choice of housing material thickness and filter bag media. For high-temperature or corrosive environments, special coatings and heat-resistant filter materials such as PPS, Nomex, or PTFE may be required.
5. Evaluate Installation Space and Equipment Dimensions
Installation space constraints will affect the overall design and dimensions of the dust collector. For instance, filter bags with lengths of 2 meters and 3 meters require different vertical clearances and result in different footprint sizes. Space availability must be considered in the early design stage.
6. Confirm Dimensional Drawings
Once the preliminary design is completed, detailed dimensional drawings should be reviewed and confirmed to ensure the unit fits the allocated space and interfaces correctly with other equipment.
7. Specify Optional Components and System Requirements
Select necessary system accessories and configurations. Common options include level indicators, differential pressure gauges, explosion vents, and variable frequency drive (VFD) fans. These features enhance monitoring, safety, and energy efficiency.
By following this structured selection process, you can ensure the chosen industrial Baghouse Dust Collector or other dust control system meets the operational, environmental, and space requirements of your specific application.
