DRY FOG DUST SUPPRESSION SYSTEM

DUST SUPPRESSION SYSTEM FOR CONVEYOR BELT

DFDS System

Synergy Spray Systems is a trusted manufacturer, supplier, and integrator of high-performance dry fog dust suppression system (DFDS) and dry fog nozzle in India. Our systems are engineered to effectively control airborne dust at the source, significantly improving air quality and reducing environmental pollution in industrial operations.

Dry fog dust suppression works by atomizing water into ultra-fine droplets that resemble fog. These tiny droplets, when released near dust-generating points, combine with dust particles—particularly respirable dust (PM10 and PM2.5)—causing them to settle without wetting the surrounding surfaces. These systems are often referred to as DFS or DFDS (Dry Fog Dust Suppression) Systems.

How Dry Fog Dust Suppression System Work

Dry fog systems operate using a carefully balanced mix of low-pressure water and compressed air, delivered through ultrasonic or air atomizing nozzles. This process produces a fog with droplet sizes ranging from 10 to 30 microns, ideal for binding fine dust particles.

The system design is tailored based on dust particle size, environmental factors, and application zones. These systems provide a cost-effective, eco-friendly alternative to conventional dust extraction setups, especially in bulk material handling plants where traditional systems may be impractical or cost-prohibitive.

Dry Fog Dust Suppression Systems provide an advanced and eco-friendly solution for controlling airborne dust in industries like mining, cement, power plants, and bulk material handling. Unlike traditional water spraying systems, dry fog technology uses ultra-fine water droplets to capture dust without wetting the material or causing operational issues.

Benefits of Dry Fog System in Industrial Dust Control

Unlike traditional water spraying systems, dry fog uses minimal water—typically 2.1 to 5.0 liters per nozzle per hour—adding less than 0.5% moisture to the material. This makes it ideal for industries where maintaining material integrity is critical.

Our dry fog nozzles are built to international standards and can be easily customized for site-specific conditions. The latest-generation nozzles feature integrated resonators for enhanced atomization and universal mounting, ensuring compatibility with existing dust suppression setups.

FAQ'S

What is dry fog?

Dry fog is the phenomenon where the spray droplets produced by atomized fog nozzles are 5 to 20 microns in size. Dry fog systems are desired and implemented in application which requires no increase in moisture or humidity.

Will it wet the surrounding area?

No, dry fog will not cause wetness as it uses a minute quantity of water. It increase the humidity less than 1% based on application.

What is the water pressure required for the system?

It requires approximately 3 to 5 bar (45 to 75 psi) of pressure for the water and air compressor pressure to be 3 to 5 bar based on application

What is the water quality required?

Water should be clean and free from harmful contaminants. A pre-filter required as part of the system. Foreign particles in the water system may clog the nozzle orifice

Does wind effect the direction of the fog?

Mildly. since the dry fog system is forced a medium pressure, wind effects the direction of the fog mildly.

What is the water pump being used?

A medium ragne pressure water pump is used as part of the system.

How big is a micron size for dry fog dust suppression system ?

A micron is very small size in the range of 10 microns to 30 micros. For example, the human hair thickness is 50-70 microns wide. dry fog dust suppression system designs are based on nature of the dust being suppressed.
