Dry fog produces atomized droplets typically between 5 and 20 microns, enabling dust suppression without increasing surface moisture or humidity.

Does wind affect the direction of the fog?

Moderate airflow may slightly influence fog direction, but proper nozzle placement and enclosure design minimize the impact.

What water pump is used in the system?

A medium-range pressure water pump is used as part of the dry fog dust suppression system.

DRY FOG DUST SUPPRESSION SYSTEM

Q: Will it wet the surrounding area?

No. Dry fog uses a very small quantity of water and increases humidity by less than 1 percent depending on the application.

Q: What is the water pressure required for the system?

The system typically operates at approximately 3 to 5 bar water pressure and 3 to 5 bar air pressure depending on the application.

Q: What is the water quality required?

Clean water with proper pre-filtration is required to prevent nozzle clogging and ensure reliable performance.

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

Dry fog droplets are typically 5 to 10 microns in size. For comparison, a human hair is about 50 to 70 microns thick.

Q: How do I choose the right dry fog system for my plant?

Selection depends on dust type, material flow rate, enclosure conditions and application area. A site assessment helps determine the optimal system design.

Q: What maintenance is required for dry fog systems?

Maintenance mainly includes routine filter cleaning, nozzle inspection and periodic checking of air and water supply components.

Q: Does dry fog replace dust extraction or bag filters?

Dry fog does not replace bag filters. It acts as a cost-effective alternative or complementary solution where dust extraction systems are impractical or expensive.

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 industrial dry fog dust suppression 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 Systems Work

A dry fogging system 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 dry fog dust suppression unit 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 systems 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.

FAQs – Dry Fog Dust Suppression Systems

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 a very small unit of measurement. Dry fog droplets typically range between 5–10 microns. For comparison, a human hair is approximately 50–70 microns thick. Dry fog system designs are customized based on the nature of the dust being suppressed

How do I choose the right dry fog system for my plant?

System selection depends on dust type, material flow rate, enclosure conditions, and application area. A site assessment helps determine the optimal system design.

Does wind affect dry fog performance?

Moderate airflow can influence fog direction slightly, but proper nozzle placement, enclosure design, and system engineering minimize wind impact.

What maintenance is required for dry fog systems?

Maintenance is minimal and mainly involves routine filter cleaning, nozzle inspection, and periodic checking of air and water supply components.

Does dry fog replace dust extraction or bag filters?

Dry fog does not replace bag filters but serves as a cost-effective alternative or complementary solution in areas where dust extraction systems are impractical or expensive.
