Bag Filter: Everything You Need to Know

Apr 12 2024

Bag Filter

A dust collection device made from woven or non-woven fabric that makes a bag that collects the dust. The cylindrical-shaped bag made from filter cloth is suspended to make a baghouse or a fabric filter.

The main purpose of these bags is to collect dust. The dust layers get deposited on the surface of the Dust collector filter bag and then in the interior of the filter cloth and collect the dust contained in the process gas. The fabric works as a surface that accumulates the dust on it. The accumulation happens due to electrostatic interaction. Together these mechanisms result in the making of dust cake.

What is a Bag Filter

Bag filters are widely used in industrial air pollution control systems across manufacturing companies to remove particulate matter (PM), such as dust, smoke, and fumes, from air or gas streams. They are cost-effective and highly efficient filtration devices that ensure cleaner air and help maintain environmental compliance.

What is the function of industrial bag filters in a boiler?

It’s important to maintain air quality for efficiency in boilers, especially in industrial settings. These bags play an important role in maintaining air quality by capturing dust particles and pollutants from the air.

What is the use of a bag filter in a boiler?

These bag filters are integral parts of any boiler system. These bag filters are also known as Baghouse dust collectors. Flue gases that are released into the atmosphere can easily be captured by these bag filters along with dust particles. This not only helps to ensure that the process is under environmental regulations but also increases efficiency by preventing equipment fouling and maintaining air quality.

Type of Bag Filter:

There are many types of bag filters present in the market. It’s important to choose the perfect one according to your requirements. These bags are categorized based on the material used, sizes, and filtration efficiency. The common types of bag filters are pulse jet bag filters, reverse air bag filters and cartridge collectors. Each bag offers unique benefits depending on the application.

Learn: How Often Should You Change Your Baghouse Filters

1. Pulse jet bag filter:

The Pulse jet system has an excellent air-to-cloth ratio. These bags are mostly used in the application of boilers, like in power and steel plants, as well as in furnaces and industrial settings for removing fumes and dust. These Pulse-jet system bags offer versatile installation options and boast a compact design, reducing costs and facilitating maintenance.

2. Reverse air bag filter:

The reverse air bag house is almost similar to the shaker bag house. They’re known for collecting particulate matter generated in industrial processes. It has an electrostatic precipitator to trap most of the dust before releasing gas into the atmosphere. It helps in balancing gas distribution and a PLC control panel. There are two types of these bags: The older style baghouse with rectangular housing and multiple compartments, and the newer reverse gas filter.

3. Shaker bag filter:

Shaker bag filters are known for removing gas and liquid contaminants by trapping particles from the air. They come in various sizes and offer efficient filter changes, reducing the cost of labor. Because of the compact, high airflow system, these bags are reusable pleated cartridge filters for space-saving design. Compressed air filter cartridges, the bags for efficient operation.

4. Cartridge bag filters:

These bag filters are used in pharmaceuticals, food processing & metalworking industries for filtering liquids and dust. They offer a larger surface area, high efficiency, and easy maintenance, making them ideal for industrial filtration needs.

5. Customize bag filter:

Many industries require specific bag filters tailored to their needs. mmp can design custom dust collector filter bags to easily handle varying temperatures, pressures, corrosive gases, or particulate properties, ensuring optimal filtration performance.

Advantages of Bag Filters

There are many advantages of bag filters, including high filtration efficiency, as they effectively capture fine dust and particles to maintain clean air and liquid systems. Below, we have detailed the key benefits:

  • Efficiency: These Dust collector filter bags and dust collector filter cages offer high filtration efficiency and capture even micron-sized particles.
  • Versatility: These bags can be customized according to every industry's need from boilers to chemical plants.
  • Cost-effectiveness: They’re cost-effective solutions to counter air pollution, requiring minimal maintenance and operating costs.
  • Environmental compliance: These bags help industries comply with stringent environmental regulations.
  • Longevity: These bag filters have a long service life if maintained properly, which contributes to sustainable operations.

Applications of Bag Filters

Bag filters are used in various industries such as power generation, cement manufacturing, pharmaceuticals, and food processing. These bag filters are installed to maintain air quality, enhance efficiency, and ensure environmental protection. Below are some common applications of bag filters:
