Industrial Dust Control to Avoid Litigation

Fogging at brick works

Controlling Dust in a Brick Works

With many workers at risk from inhaling dust, industrial dust control is essential. Employers are legally responsible for protecting all individuals within their facility from the risk of dust inhalation.

Just a small amount of dust can be harmful, but consistently dusty environments can even be lethal. Severe and debilitating lung conditions, silicosis and COPD can all result from working in a dusty environment. They can mean hundreds of working hours off sick for some people. For others, it can mean having to give up work altogether. Both can be prevented.

Every worker has the right to work in a healthy environment where dust levels are controlled. A dust-free environment can also improve motivation and productivity of staff.

How can we reduce dust?

The before and after pictures of this grain loader based at the Port of Tyne clearly show how MicronFog™, once installed, controls the dust at the transfer point.

As with the grain loading facility, many industrial processes create breathable dust, especially containing silica. During processes handling root vegetables or vegetables with soil on the roots, silica dust becomes airborne as the soil dries and the produce is moved.

Mining, quarrying and mineral or stone handling processes inevitably create fine airborne dust. So do biomass or wood waste processing - the list goes on and on.

In all working environments, employers and contractors are legally required to control dust levels and the HSE will inspect to ensure the employer is doing everything within their power to prevent dust staying in the air. This is where MicronFog™ comes in.

Which system is best for industrial dust control?

Many businesses go about controlling dust by extraction or dust collection, using methods such as inertial separators, fabric filters, wet scrubbers, electrostatic precipitators and dust collectors.

Most of these are expensive, both in terms of power and consumables, such as filters.

The solution: fine fog

Fine fog, as created by Renby’s MicronFog™ system, is a highly effective dust suppression and control solution which removes the need for any of these collector or extraction systems.

Although there are a few applications for which it may not be suited, we have found that around 80% of facilities in need of industrial dust control can be treated with fog instead of expensive, power-hungry dust extraction systems.

Energy Use

By using high-pressure water, the energy requirement is approximately ⅛ of alternative techniques and uses relatively small amounts of power. All systems come with motor inverters to further reduce power consumption.

As an example, a major onion packer uses a system that consumes less than 1.25kW power to suppress dust in a building with an area of 1100m and uses 28 nozzles.

At the other end of the scale, a biomass store with a floor area of 6000m2 uses 5.5kW with 500 low flow nozzles. In both cases, the systems must not wet the product in the building. This has been achieved through the use of careful nozzle placement and electronic controls on the system. Those familiar with dust collection systems will find these power figures remarkably low, making fog a cost-effective solution for industrial dust control in large warehouse type areas.

A Practical Home Demonstration of Misting Dust Suppression

plant misterMicronFog’s™ tiny fog droplets of less than 15 microns attach to airborne dust particles and the dust simply falls to the ground.

A very simple demonstration of this principle can be done at home, although the droplet size is larger and you may wet the floor a little.

Take a plant mister and a broom. Sweep a dry area where there is dust such as a garage, shed or greenhouse. You can see the dust in the air. Now spray the plant mister as firmly as possible through the dust clouds and watch the water droplets and dust drop to the ground, then the resultant dust on the floor can be swept without more dust being kicked up.

Of course, being a highly controlled and high pressure fogging system, MicronFog™ produces much finer and more consistent fog droplets than a plant mister. The fog is so fine that it does not wet the floor or anything else in the area, as it either evaporates or combines with the dust falling to the floor, but the basic principle is the same.
