Dusting solutions to control and reduce dust emissions into the atmosphere

Dedusting solutions are processes used in the industry to eliminate dust and/or solid particles from the environment with the main objectives of improving the working conditions and safety of workers and complying with environmental regulations. Equally, and of no less importance, a well-implemented dedusting solution will eliminate unnecessary maintenance costs, as well as recovery of product that may be valuable to the user.

Dedusting solutions play a crucial role in the industry by removing solid particles and dust from the environment. These processes not only improve working conditions and worker safety, but also ensure compliance with environmental regulations. Additionally, effective implementation of dedusting systems can result in significant maintenance and product recovery savings.

Of the dedusting solutions, two groups or categories can be distinguished:

  • Ancillary dedusting solutions:
    These solutions are vital to maintaining a clean and safe environment, although they do not directly contribute to the production process. Objectives include controlling the immission and emission of particles into the environment, product recovery and the elimination of unnecessary maintenance expenses. Some common ancillary dedusting applications include material transfer, product unloading and loading, screening, storage in silos, dust emission in warehouses and ventilation.

  • Process dedusting solutions:
    These solutions are directly linked to the production process. In addition to meeting dust emission control objectives, they must operate constantly and efficiently. Examples of process dedusting applications include vacuuming furnaces, boilers, combustion processes, mills, atomisers, dryers, etc.

What does a dedusting installation consist of?

Broadly speaking, a dedusting installation consists of five main elements that work together to ensure effective operation:

  • Capture system:
    Responsible for capturing dust at the closest source of the process, using enclosures, collection hoods, regulation valves and ducts.

 

  • Filtration equipment:
    Retains and separates dust and particles from the air with equipment such as dust collectors, cartridge filters, HEPA filters, ceramic filters, wet scrubbers and cyclones.

 

  • Fan:
    Generates the flow and pressure necessary to capture the particles at the source and overcome pressure losses throughout the circuit.

 

  • Dust extraction system:
    Discharges captured and filtered dust for return to the process or storage using endless conveyors, rotary valves or double flap valves and pneumatic conveying systems.

  • Control system:
    Regulates the work point, the cleaning system of the filtration equipment. Provides information for predictive and preventive maintenance.

It must be highlighted that the specific configuration of a dedusting installation may vary depending on the needs and characteristics of the industrial process.

Keys to optimal efficiency of a dedusting solution

Although dedusting systems are usually “simple” once integrated, it is essential to ensure their optimal efficiency. Some factors that can affect efficiency include:

  • Inadequate enclosures and hoods: Modifications to these structures can affect the suction flow and compromise the efficiency of the system.

  • Horizontal ducts: Dust build-up in horizontal ducts can reduce efficiency; we recommend avoiding them or performing adequate preventive maintenance.

  • Unplanned modifications: Adding to the installation without adjusting the filtration system and fan can affect overall performance.

  • Incorrect filtration system selection: A poor choice of filter fabric or inadequate configuration can compromise the effectiveness of the system.

  • Operating conditions: Crucial to designing an efficient installation is understanding operating conditions such as gas concentration, gas temperature and gas humidity, as well as dust concentration and typology.

  • Improper dust discharge: Poorly designed elements can cause frequent stops and unplanned maintenance.

In cases of low efficiency, it is advisable to have experts to audit and detect the real causes, proposing improvements for an efficient dusting solution. For more information, explore our Technical Audit services.
