| Dust
and Fume Control
Health & safety legislation exists to
ensure the welfare of employees in the workplace, making
it the responsibility of the employee to identify any
hazardous substances used or produced in processes. A
large number of industrial processes require effective
and efficient control of different types of fumes and
dusts to ensure protection of employees and compliance
with the CoSHH Regulations 2002 (As Amended). MECHON specialises
in extraction systems that remove and filter harmful airborne
substances and hazardous dusts from working environments.
MECHON utilises local exhaust ventilation (LEV) systems
as the main control technique for reducing employee exposure
to hazardous substances. Hoods are employed to capture
the fumes at source, conveying them through a system of
ductwork to either an abatement plant or atmosphere. The
MECHON solution also focuses on the nature of the substance,
including hazard identification, occupational (workplace)
exposure limits, toxicity, explosive limits, corrosivity,
and chemical compatibility.
Hoods Design
Whilst any abatement (filtration) plant
forms a crucial part of any system, MECHON pays particular
attention to the design of the extraction hoods and ductwork
systems: correctly designed hoods and ductwork systems
will ensure lower airborne exposure levels, reduced extraction
rates, and minimal disruption to the process.
Specialised hoods include
| |
Rear extract booths |
 |
Laminar downflow
booths |
| |
Canopy Hoods |
 |
Bag filling stations |
| |
Spray Booths |
 |
Air brake hoods |
| |
Containment enclosures |
 |
Fume cupboards |
| |
Downward draft tables |
 |
Articulated Arms |
Dust Control
Systems
Extracted dusts must be suitably filtered
to ensure limited impact on the surrounding environment
and guarantee compliance with the Environmental Protection
and Pollution Prevention & Control Acts. Various filter
types are at our disposal to achieve this aim, these filters
include:
| |
Reverse Jet Bag
Filters (normally with polyester-needlefelt elements) |
 |
HEPA Filters |
| |
Cartridge Filters |
 |
Wet Collectors |
| |
Shaker Filters |
 |
High Efficiency cyclones |
| |
Silo venting filters |
 |
Dust Suppression systems |
| |
Sintered Filters |
|
|
Fume Control
Systems
Fume control poses a particular challenge
when abatement and dispersion is required: statuary instruments
such as the Environmental Protection Act, Pollution Prevention
& Control Regulations, and the Solvent Emissions Regulations
stipulate how substances are discharged to atmosphere.
Abatement techniques include
| |
Activated carbon
filters |
 |
Electrostatic precipitators |
| |
Fume scrubbers |
 |
Chemical filters |
| |
Oil mist filters |
 |
HEPA Filters |
MECHON has a vast amount of experience in
the handling of hazardous dusts, which are extremely toxic
or at high risk of causing dust explosions. Specialised
ductwork systems and filtration plant, such as wet collectors
(precipitators) and sintered type filters, are installed
in these types of applications. All equipment installed
in potentially explosive atmospheres are ATEX approved,
ensuring compliance with the DSEAR Regulations 2002.
