Dust Suppression System

We are one of the leading manufacturers of Dust Suppression System that are instrumental in removing dust particles from the atmosphere in a particular location. The system works with the help of atomizing nozzles in series that is fitted in a manifold manner to cover the area. These high capacity nozzles produce a hollow cone spray pattern.

Our system produces very fine mist droplets that float freely in the air and create fog. The fine spray pattern covers the particular area continuously so that the dust gets heavier and falls down. The drops are very small and the spray pattern is affected by air frictions and currents several feet from the nozzle, depending on pressure and nozzle capacity. Hence, the particular area remains without any particulate matter, and the solid waste collected on the floor can be removed by cleaning the area.

The SDI comprises a complete line of controls and accessories that are required for setting up a system with the assistance of atomizing series nozzles. In a pressure-fed system, the liquid is supplied under pressure to the nozzles. Pressure regulators are meant for controlling fluid delivery pressure. The filter and liquid strainer ensure that the supplied water is free of particulate. Operational control is main-trained by sensors and solenoid valves that are used in conjunction with the various hardware assemblies.

Method of operation

The tap water if filled into the high pressure pump converts the low pressure water into high pressure. It is unloaded by a un-loader or a safety regulating valve through high pressure resisting hoses or SS 304 seamless pipe lines. The nozzles act as an immediate resisting agent and deliver the high pressure water. This delivered water has an impact of pressure varying from 0 bar to 25 bar.

Further, these are designed to deliver the high pressure water in to a transparent spray that creates a misty formation or a foggy discharge to suppress dust and for humidification of the atmosphere. Dust present in the atmosphere comes in contact with moisture in the fog. Owing to the heaviness of water along with the gravitational force, the dust drops to the ground. The unused water is once again diverted to the pump through a by-pass hose for safety methods.

We manufacture a wide range of Pipe Lines & Mist Atomization Nozzles that is in compliance with the standards of the industry. The pipe lines SS 304 seamless pipes of Indian standard with outer diameter of 14 mm and inner diameter of 11 mm.  In addition to these, the nozzles are fitted at customized equal distance throughout the pipe line as per the requirement of the application area.

Construction:

It is an apparatus for applying suntan lotion including a liquid tight enclosure of generally cylindrical shape. The upper wall portions are tilted inwardly to form a central neck enclosure. A door at the side walls of the enclosure is spring biased to the closed position. Lotion mist ports are disposed about the interior of the enclosure and supplied from a lotion distribution tube which in turn is supplied from at least one atomizing nozzle. A pump is installed for pumping the liquid lotion from a supply dispenser to the atomizing nozzles.

Working Methodology:

• As the lotion is pumped through the atomizing nozzle, it is formed into mist droplets which are communicated to the distribution pipe & further, to the mist outlets in the chamber
• The droplets contact the body of the person in the chamber & are applied to the skin
• A re-circulating pump is provided for evacuating the misted droplets & re-circulates them into the distribution tube by means of an impeller fan.
• Lotion which may condense inside the impeller is stored in a used lotion recovery reservoir. The pump and motor which drives the pump & impeller fan is operated by token operator control located outside the enclosure.

Principle of Operation

Fogging & Misting dust control process is based on the principal of misting. The dust particles released from the material being handled (e.g., conveyer points, screens, above and below crushers, and dump areas) are exposed to an environment that comprises massive quantities of very fine water particles. This environment is similar to very wet fog.  The dust particles mingle with the water particles, increase in weight, and then fall back to their source of origin.

The percentage of water added to the material is extremely low because only the fugitive dust is affected. This controls the efficiency of the system that can be in excess of 95% depending on the application.

Why use water for misting & fogging systems?

We make use of efficient dry collection systems that is highly expensive and is applicable only to sources that can be enclosed. Filter fabrics have limitations with heap of material in a pile and the disposal of filters \ fabrics often produces secondary emissions. Water spray systems are the most efficient and cost effective means of dust control for process and fugitive dust emissions. This is due to the simple fact that the dust remains with the product of origin, while it is being disturbed.

Dust Suppression Technology

Proper control of fugitive dust from surface material handling systems (dumping, conveying, screening, crushing, and storing) is a matter of concern among designers and operators in many industries such as mining & minerals processing, wood products, chemical, and power generation.

Dust is created across these industries due to many operations. In most areas, the control of dust is mandatory for federal, state, and/or local regulations. The enforcement becomes more rigid and the penalties imposed for operating without proper dust controls also becomes risky. Keeping in mind the cost of a regulatory fine along with the enhanced work environment, the dust control process becomes an investment in safe operations.

Spray Controlling Unit is meant for controlling a sprayer comprising a first and a second scrolling means operatively connected to the sprayer.  This involves:

• The first scrolling which changes the status of the plurality of spray units in a first direction along one dimension
• The second scrolling changes the status of the plurality of spray units in a second direction along the dimension

The first scrolling and second scrolling means are independently selected from the group comprising a wheel-based controlling means and a sliding switch-based controlling means.

Construction:

• MS fabricated closed cabin

• In built pump with motor on a separate base frame for service purpose
• Twin filters for prevent the foreign particle entered in water
• Hand removable guide bowl for easy maintenance
• In built SS 304 water tank to prevent the pump for dry running
• In built electrical panel to meet the customer requirements
