SMALL DROPS, BIG IMPACT: DUST MANAGEMENT

SMALL DROPS BIG IMPAC

We protect our customers from dust and its consequences. The topic of dust suppression has become enormously important in the last years – on the one hand, due to stricter requirements imposed by the authorities and on the other hand due to increasing environmental awareness. At EmiControls we not only fight dust through competent consulting, plant engineering, and implementation of dust control systems but also offer a decisive added value for your company: ›› Cost and time savings: maximum results thanks to minimum use of resources ›› Happy employees, safe working conditions, and...

SMALL PARTICLES, SERIOUS CONSEQUENCES: THIS IS WHY DUST SUPPRESSION IS IMPORTANT Dust has various negative effects on people as well as the environment and can lead to serious consequences if you are exposed to it unprotected for a longer period of time. How to properly abate dust depends on several factors.

What types of dust exists Dust is the finest particles suspended in In the context of workplace safety, it is im- the air, created by mechanical processes. portant to know the following types of dust: Dust particles differ in size, shape, colour, ›› E-dust is the inhalable fraction of the dust chemical composition, physical properties, and gets into the mouth and nose and their origin and formation. Size: the particles are smaller than 100 µm. Dust is practically omnipresent and has ›› Tracheobronchial dust reaches the upper various sources: industry, transport, agricul- ture, fires, nature...

SMALL DROPS, BIG IMPACT THE SECRET OF WATER MIST The expectation on the effectiveness of dust suppression systems has increased enormously in recent years. But how does efficient dust suppression look like? The most important element is the water mist itself: the fine mist moistens the dust, makes it heavy and brings it to the ground without forming puddles or muddying the material. Water mist has a double function in order to reduce unwanted dust emissions in the air: ›› by moistening the air, the dust floating in it is brought to the ground ›› by moistening the surfaces (material as well...

The graphic shows how the V22 dust controller distributes the water. The correct distribution of the water mist Another crucial point for successful dust next to the water mist as well on these suppression is the optimal distribution of factors: the general dust tendency of the material, plant-specific conditions such The amount of dust in the air is specified as [mg/m³]. Through many years of experience as well as tests and trials with independent institutes, we know exactly Effective dust suppression depends as conveying speed, drop height of the material, but also the ambient conditions...

THE TECHNOLOGY MAKES THE DIFFERENCE Turbine Thanks to innovative materials and refined aerodynamics of the blades, our machines are: ›› particularly quiet and ›› energy efficient Low energy consumption Thanks to the special aerodynamics of the blades as well as the nozzle head, our machines offer less consumption for the same performance. Compared to other machines, they consume on average 25% less energy by keeping the same throwing

Nozzle head The internal nozzle head makes optimum use of the air flow, since the direction of the water spray is parallel to the airflow (laminar). In comparison, with an external nozzle ring*, the water is sprayed obliquely into the airflow and creates a turbulent flow, which is accompanied by a loss of power. The nozzle ring has the following advantages: ›› better performance ›› machine is less affected by wind * Our larger models have a nozzle ring in addition to the nozzle head. This is needed to put through the necessary amount of water for optimal dust abatement. Water supply The...

WE PROTECT OUR CUSTOMERS FROM DUST PROBLEMS Behind every well-functioning plant stands an excellent planning as well as consulting team. At EmiControls, nothing is left to chance: before we start a project, we personally visit the site and provide our customers with competent and professional advice. Once the problem has been evaluated, we work hard to find the right solution. Our project management team starts with the planning of the system and, in constant exchange with our customers, finalizes the plans and then organizes the installation of the plant on schedule. After a successful...

Problem identification and solving To guarantee optimal results, the demands and needs of our customers are the main focus of our planning from the very first consultation

Step 1 Assessment of the actual state ›› Definition of the dust source ›› Measurement and logging of the intensity and concentration of dust emission (over a longer period of time) ›› Determination of the different types of dust ›› Analysis of material flows Step 2 Definition of the desired state ›› Which legal aspects have to be considered in terms of environmental protection and occupational safety? ›› Based on the dust measurements During an initial on-site inspection, we analyze the sources of dust and the type as well and possible requirements from au- as the quantity of dust. With the...

Competent organization during installation and commissioning After the planning and coordination phase, we begin with the installation of the system. An EmiControls project manager is responsible for supervising and coordinating the work while serving as the primary contact for the customer. The specific nature of each dust problem always requires an individual approach to be perfectly tailored to the customer’s needs. At the end of the construction work, the project manager and his team take over the commissioning and, after a detailed training session, hand over the dust suppression...
