Cannons

What is dust suppression?
La supresión de polvo se refiere a cualquier método de control de polvo que utilice agua. Se emplea comúnmente en estrategias de mitigación de polvo debido a su rentabilidad, accesibilidad y seguridad ambiental.
Hay dos tipos principales de supresión de polvo:
Supresión de superficies: El agua se aplica directamente a los materiales para aumentar el peso y la cohesión, evitando que el polvo se transporte por el aire.
Supresión en el aire: Las partículas finas de niebla interactúan con el polvo en el aire, aumentando el peso de las partículas y conduciéndolas al suelo.
La tecnología de niebla atomizada sobresale en ambas aplicaciones. A diferencia de los sistemas convencionales, que sobresaturan los materiales o no controlan el polvo en el aire, la niebla atomizada equilibra el tamaño de las gotas y el contenido de humedad para una gestión integral del polvo.
What is atomized mist?
Atomization is the process of breaking down a liquid into extremely fine droplets. In the context of dust control, atomized mist technology uses specialized nozzles to generate millions of microdroplets, ensuring maximum surface coverage. Different nozzle configurations and engineering techniques allow for various droplet sizes, optimizing effectiveness for different applications.
Why is atomized mist used for dust control?
La niebla atomizada se usa ampliamente en diversas industrias, desde el enfriamiento de espacios para eventos hasta la regulación de la humedad para el curado del hormigón. Su principal ventaja en la supresión de polvo radica en su capacidad para hacer coincidir el tamaño de las gotas de agua con las partículas de polvo. Cuando la gota es demasiado grande, las partículas de polvo pueden seguir el flujo de aire a su alrededor en lugar de chocar. Sin embargo, cuando ambos tamaños son comparables, las gotas capturan y sedimentan eficazmente el polvo.
Además, la niebla atomizada consume significativamente menos agua que los métodos tradicionales como las mangueras o los sistemas de rociadores, que pueden usar hasta 20 veces más agua de la necesaria. A diferencia de estos sistemas de alto flujo, la niebla atomizada está diseñada específicamente para la supresión eficiente y específica del polvo.
How important is water quality?
Water quality plays a crucial role in maintaining system performance. While potable water is ideal, non-potable water can also be used with the proper filtration systems. It is important to inspect and clean nozzles regularly, as dirty water can cause blockages and reduce efficiency.
What type of water connections do your units use?
La mayoría de nuestros sistemas están equipados con una conexión de agua BSP (DN25) de 1". Nuestros modelos M5 manuales más pequeños cuentan con una conexión BSP de 3/4".
What are the electrical requirements?
