Filson Baghouse Filter Working Principle

Filson baghouse filter works mainly depending on the filter bag inside the dust collector. The number of bags may vary by type but can be assembled from a half dozen to several hundred. It’s totally up to your needs.

Filter Bags Materials

Filter Bags Materials

When a baghouse dust collector starts to work, the polluted air is drawn in through the inlet. At this time, the heavier and bigger particles fall down directly, while finer dust goes further to the filter bag.

Depending on the cleaning method of the baghouse dust collector, the dust may cake on the inside or outside surface of the filters while passing through.

Industrial Dust Type

Industrial Dust Type

As dirty dust, smoke, and particles are left behind, filtered air exits through the fan at the outlet at the top of the baghouse.

As the cleaning cycle goes forward, the agglomerated dust falls from the bag filters and is deposited into the collection hopper and moved to a discharge unit for final disposal.

What Does a Baghouse Dust Collector Consist Of?

The outside surface of a baghouse dust collector may be different depending on design, but for any type of baghouse, the basic components are the same.

  • Fun

Fun in the baghouse dust collector is used to push or send dirty air through the filter bag.

  • Hopper

Usually, the hopper is installed at the bottom of the baghouse dust collector. When dusty air enters the bag filter, the large particles settle down and fall into the dust hopper under the function of gravity.

  • Filter medium

The filter medium refers to the fabric bags. The filter bags are made of woven or non-woven felt to filter the dust-containing gas. They are supported at the top or the bottom or have a bag cage inside them.

When the gas containing fine dust passes through the filter media, the dust is retained, so that the gas released to the environment is purified.

  • Dust cleaning system

The collected dust gathers on the inside or outside surface of the filter bags. Then a dust cleaning system is needed to handle the contaminants. Filson provides shaker type, pulse jet type and reverses air type baghouse to accomplish the cleaning task.

  • Discharge device

Typically, a baghouse dust collector has a drawer to store the dust and can be emptied. And most large baghouses in an industrial application have automatic discharge units.

Baghouse Dust Collector Components

How Does a Baghouse Dust Collector Work?

The working principle of a dust collector consists of a filtration process and an ash cleaning process.

The polluted air is drawn into the dust collector from the inlet. Then it will be pushed to pass through the filter bags. During this process, the large and heavy particles drop directly into the hopper at the bottom and the fine and light particles go forward.

Filter bags can be customized into different micron ratings from 0.5 to 200 microns. With excellent filtration efficiency, the dust is collected on the inside or outside surface of the bags, it depends on the cleaning method.

Finally, the clear air is released from the outlet of the collector to the environment or the workplace.

After a period of use, the baghouse will stop to clean the bags.

Take pulse jet as an example:

When the pulse valve opens, a high-speed and high-pressure airflow flies to the filter bag. The filter bag is under pressure and expands dramatically. The dust deposited on the surface of the filter bags falls into the hopper to achieve the effect of dust cleaning.

How Do You Size a Baghouse Dust Collector?

There are many factors involved in the design of baghouse dust collectors and the most vital factor is the handling air volume which decides the scale of the baghouse.

As soon as the handling air volume is decided, the necessary filtration area can be determined according to the filter air velocity.

Besides the air volume, the following elements should be taken into consideration when the size or choosing a suitable baghouse dust collector: operating temperature, gas composition, inlet and outlet dust concentration, dust properties…

Where Are Baghouse Filters Used?

With the development of bag filter technology and the increasing environmental requirements, baghouse filters are used wider and wider.

Baghouse dust collectors are now available to handle high temperature, high humidity, viscous, explosive, abrasive fumes, and even filter air containing ultra-fine dust.

This kind of dust collector can be applied to various industries including the chemical industry, pharmaceutical industry, power plant, food and beverage, steel mill, and other applications with high purification requirements.

What Is The Air-to-Cloth Ratio In Baghouse?

The air-to-cloth ratio, also known as the surface filtration velocity, is the ratio of the volume of dust-containing gas processed per unit time to the area of the filter cloth.

There are gross air-to-cloth ratio and net air-to-cloth ratio.

The former refers to the ratio of the volume of the inlet air to the total filter cloth area of the dust collector. And the latter refers to the ratio of the volume of the inlet air to the filter cloth area of the operating bags. For a small bag filter, the difference between the two is large.

The air-to-cloth ratio is an important design parameter and an important indicator to determine the performance and economical efficiency of the baghouse.

Considering the dust removal performance, the selection of air-to-cloth ratio should take into account the dust collector type, dust cleaning method, filter media type, dust and gas properties.

What is a Shaker Baghouse?

Shaker baghouse is also known as a shaker dust collector or shaker fabric filter.

It is a dust collector designing and adopting a shaker cleaning system to remove the aggregated dust particles from the surface of the filter bags. It realizes the cleaning effect by mechanically shaking the filter bags.

Normally, the filter bags of a shaker baghouse won’t contain rings or cages, the design is complying with the working principle of the equipment.

What Are The Advantages Of Using Baghouse Dust Collector?

(1) High dust removal efficiency: generally above 99% and with high classification efficiency for fine dust of submicron particles.

(2) Wide range of processing air volume: only a few cubic meters per minute for small ones and up to tens of thousands of cubic meters per minute for industrial furnace flue gas de-dusting to reduce the emission of air pollutants.

(3) Simple structure, easy maintenance, and operation.

(4) Lower cost than that of electrostatic dust collector on the premise of ensuring the same high dust removal efficiency.

(5) When glass fiber, PTFE, P84, and other high-temperature resistant filter media are used, it can operate under high-temperature conditions above 200℃.

(6) Insensitive to the characteristics of dust, it is not affected by dust and electrical resistance.

What Is An Advantage Of a Baghouse Compared To An Electrostatic Precipitator?
  • O&M comparison:

Baghouse is stable in operation and emission, simple in control. It has no high-pressure equipment for good safety and less disturbing factors to dust removal efficiency.

Electrostatic precipitator has many disturbing factors in the operation process, unstable in emission, relatively complicated control, and high safety protection requirements for high voltage equipment.

  • Operation and maintenance costs comparison:

Baghouse fan energy consumption is large, dust cleaning energy consumption is small. The maintenance and overhaul cost of the bag filter is mainly the bag replacement cost.

Electrostatic precipitator fan energy consumption is small, electrical energy consumption is large. Its maintenance and repair costs are mainly for the anode plate, cathode wire, vibration hammer, and other replacements. The cost would be really high.

  • Inspection and maintenance comparison:

The baghouse dust collector can be serviced without stopping which means online inspection and repair.

Electrostatic precipitators must be shut down for maintenance.

Can I Reuse My Baghouse Cages When I Change My Filters?

It depends.

In some conditions, you can reuse the baghouse cages once or maybe more times. But in many industrial applications, it’s better not to reuse the bag cages.

The baghouse cages can be damaged by physical force like bending, breaking during the maintenance process, or by chemical corrosion. Besides, temperature deviation can warp cages as well.

The damaged cages will decrease the dust removal efficiency which results in lower profits for your business and lead to the malfunction of the whole equipment. That would make you pay dearly.

Remember to weigh the pros and cons before making the decision. Although some costs can be saved by reusing the cages, once the equipment breaks down, the consequences can be unimaginable.

Shaker Baghouse Dust Collector

How Do I Clean My Baghouse?

There are three main cleaning methods of baghouse:

  • Gas cleaning:

Gas cleaning is a common method to remove the accumulated dust on the filter bag with the help of high-pressure gas or external atmospheric backflushing, including pulse jet cleaning, reverse air cleaning, and reverse-suction air cleaning.

  • Mechanical vibration cleaning:

For the filter bag, it can be divided into top vibration cleaning and central vibration cleaning. It realizes its function with the help of a mechanical vibration device. The device periodically vibrates each row of filter bags, in turn, to remove the accumulated dust on the filter bags.

  • Manual tapping:

The method is to tap each filter bag manually to remove the accumulated dust on the filter bag.

What Should I Do To Maintain The Equipment?

If you want your baghouse dust collector to operate for a longer term, you are recommended to maintain the equipment regularly and correctly.

  • Always check the operation of control valves, pulse valves, meters, etc.
  • Verify that the air volume and pressure and temperature at each test point are in accordance with the design.
  • Confirm the installation of the filter bag, whether there is a bag drop, loose, or tear after use. That can be judged by visual inspection of the chimney emissions after the operation.
  • Prevent condensation of filter bags or the fabric perforations will be blocked resulting in the failure of the equipment.
How Does Your Baghouse Dust Collector Prevent Dust Explosion?

For dust explosion, it should have three elements: an ignition source, combustible fine dust, dust clouds in the explosive concentration range formed by the suspended dust in the air.

An explosion occurs only if these three elements are present at the same time. Therefore, as long as one of the conditions is eliminated, the explosion will be prevented. The following technical measures are often used in baghouse dust collectors:

  • Set the dust plate inside the dust collector and adjust it to the right angle.
  • Use anti-static filter bags inside the baghouse dust collector.
  • Install safety valves and essential fire suppression equipment. The purpose of setting a safety valve is not to prevent an explosion, but to use it to limit the scope of the explosion and reduce the number of explosions.
  • Take necessary fire protection measures in the dust removal system.
  • Adopt open-air arrangements for operational safety.
  • Set up spark trapping devices on pipelines.
  • Control the inlet dust concentration and add non-combustible powder.
