VEL INNOVATIVE TECHNOLOGIES PRIVATE LIMITED in joint collaboration with NODOLINI SPRINKLERS from Italy are proud to present a wide & diversified range of dust suppression systems involving high performance, heavy duty sprinklers. Vel Innovative Technologies are team of engineering experts actively involved in the design. development. manufacture and supply of various dust suppression systems including those involving heavy duty sprinklers, one among many other products, solutions, services provided to Process Industries. Nodolini are pioneers in the field of sprinkler manufacturing with over 60 years experience in the field. The sprinklers are developed through our joint effort & experience of actual client requirements.

We offer total turnkey solutions for all types of open & exposed dust control situations (eg. stockpiles, haul roads. mines. open yards. thermal power plants etc). Our purpose includes design, engineering, manufacture, supply & commissioning of the system. Our goal is to provide effective solutions to the problems of fugitive dust emissions in the above mentioned areas with minimum consumption of water and electricity.

The key component of these systems – sprinklers are designed to operate in adverse conditions, high pressure (15 bar), and have protected moving & exposed parts, enabling long life & trouble free performance for years of continuous service. We have developed three lines of sprinklers for our dust suppression systems:

S.W. = DUST SUPPRESSION (STANDARD MODEL) WITH WATERS AND ENVIRONMENTS NOT CORROSIVE

C.W. = DUST SUPPRESSION WITH CORROSIVE LIQUIDS. WASTE WATERS, SEAWATER, CORROSIVE ENVIRONMENT

 A.W. = DUST SUPPRESSION WITH ABRASIVE LIQUIDS (MINING), CORROSIVE LIQUIDS. WASTE WATERS, SEAWATER. CORROSIVE ENVIRONMENT

Our team is always ready to evaluate and propose appropriate solutions for all type of dust suppression require-ments. Our technical staff is always available to advise appropriate models/solution based on the inputs received from our customers with respect to site conditions like quality of water, windy conditions, complicated layouts, characteristic of the dust emission, permissible dust emission levels etc.

Atomization is designed to reduce the surface tension of the water droplets, while increasing the number of droplets in a given area and eliminating the need for the addition of surfactants or other additives. The low level of water added through the fog/mist systems – typically at 0.01% to 0.05% by weight of the material – generally will not degrade the performance of the material.

Single-Fluid Atomization

This system uses an ultra-fine stream of water pumped at high pressure through single-fluid atomizing nozzles. It does not require compressed air or an additional power source other than the electricity to run its pump. Single-fluid nozzles use hydraulic atomization to generate the mist. Water is forced under pressure through a small orifice that shatters the water droplets into microscopic particles. The energy created by the high-pressure is used to atomize the water droplets, rather than increase water velocity, thereby minimizing displaced air.

Features Of The Wet Fog Dust Suppression Systems:

• Fog systems provide highly effective dust capture combined with economical capital and operating costs.
• A well designed fogging system can provide excellent control of dust at the point of application without the need for chemical additives. Since fog systems only add water, they protect the integrity of the customer process.
• Total moisture addition to the bulk material can be realistically less than 0.1%. This makes fog suppression systems attractive in industries that cannot tolerate excess moisture, such as cement and lime production.
• For truly effective performance, fog dust suppression systems require tight enclosure of the transfer point that minimises turbulent, high-velocity air movement through the system.
• These systems consist of atomizing nozzles which produce a very fine mist droplets that float freely in the air and create fog. The spray pattern covers the particular area continuously so that the dust gets heavier and falls down.

When vast open spaces require dust suppression and a semi permanent system is not a practical option, the solution may lie with the introduction of a fog cannon to the site. These huge mobile and expensive units can utilise up to 60 hydraulic spray nozzles mounted circumferentially around the outlet head of a large fan assisted barrel. The concentration of nozzle spray together with the high flow of air from the fan, throws the droplets many metres towards the source of the dust activity. The droplets scatter in a plume of relatively soft spray and can capture fugitive dust before it becomes airborne and a major problem.
