Control of Dust Emission
Limiting the emission of dust and fumes has both environmental and health benefits but there are also more tangible advantages of controlling dust in the workplace.
- Improved working conditions aids productivity.
- Economical gain from reclaimed product.
- Improved plant access for maintenance.
- Reduced downtime of productive plant.
- Reduced cost of wear of equipment.
- Improved safety due to better visibility.
- Reduced fire/explosion risk.
The large number of variables encountered in processed that create airborne dust require a multi- diciplinary approach to solve each individual case.
Status Projects specialise in providing the best solution to each individual dust problem.
We have been active in this discipline for 30 years and work closely with the client’s design team to ensure an integrated solution at time of initial design.
Methods to control dust emission include:
The first step in containing dust emission is to enclose the dust source as much as possible.
The efficiency of both Dust Extraction and Dust Suppression systems will be greatly improved if the dust source can be enclosed to a large degree.
Source enclosure are designed to suit the application and have to allow for maintenance access.
Dust Suppression refers to the subdual of the dust at the point of origin by means of spraying moisture onto the dust source.
The function of the moisture is to bind the airborne dust particles together thus creating an agglomeration of particles with increased mass allowing them to settle out of the air and back into the material stream.
One limitation of this type of system is that it can only be used in processes where the product can tolerate the addition of moisture.
Due to the combination of dust and moisture these type of systems do require regular maintenance.
Collection / Dust Extraction
Dust Extraction or Filtration refers to the action of removing air containing airborne dust from the dust source and the filtation of the contaminated air to extract the dust particles.
Filtered air is returned to the atmosphere and the dust is collected as a by-product or re-introduced to the material stream.
Collection of airborne dust by means of extracting airflow from the dust source and filtration of the contaminated air.
Suppressing of airborne dust at the source by means of moisture sprayed onto the dust.
