Selecting a dust collector for a particular environment can be more challenging than it may first appear. The characteristics of the specific dust to be collected must be taken into consideration.
Some questions to ponder on will include;
- What is the size of the dust to be collected?
- If small, how small? It helps to understand here that dust can be big particles between 2.5 and 10 microns in size, small particles between 2.5 microns and smaller particles 2.0 microns are 50 times smaller than a typical human hair.
- Does your environment produce a mixture of all the above sizes? How abrasive are they?
- Does the dust have moisture absorbing characteristics?
- Does the dust readily form or collect in a mass or not at all?
- Is it combustible or prone to explosive? Is it corrosive or toxic or unstable?
These vital considerations will assist in determining the most effective dust collection system to use. Additionally, careful consideration must be given to the properties and conditions of the gas stream that enters and passes through the dust collector.
The characteristics of the gas stream will have a significant impact on the selection of the dust collection system as much, if not more than the dust characteristics. These two factors, that is, dust and gas stream characteristics can make for some challenging equipment selections, especially in very high temperature environments.
Envirox supplies a range of dust collectors tailored to handle this kind of challenge in larger industrial plants with hot gas applications. Their Nederman FD Filter and FS Filter models are ideal for use in very high temperatures.
These dust collectors are equipped with specialised filter media that are capable of handling dust and hot gases in a wide range of industrial activities and applications.
Nederman FD Filter
Also known as the FD flat bag dust collector, the Nederman FD Filter has an air volume range of 17 000 to 340 000. It is an ideal choice for your typical dust control and process applications such as hot metal processes, which includes aluminium/non-ferrous metals, iron and steel, waste incineration/biomass, crematoria, foundry and asphalt plants.
Nederman FS Filter
Otherwise known as the FS Flat Bag Dust Collector, the Nederman FS Filter has an air volume range of 10 000 to 250 000 m³ / h. It is the perfect choice for use with hot gases in the extraction of dust and particles, combustible dust, welding and cutting, and smoke and fume extraction.
Using the FD Filter and FS Filter dust collection system offers many benefits to industries, some of which are summarised below:
- Robust waterproof welded steel construction
- Increased overall efficiency
- Protection of downstream installations
- Better integration of dust filtration into entire manufacturing process
- Long filter bag life
- Low emissions
