Clean air in industrial and manufacturing facilities is not a luxury, but a critical necessity. Polluted air can negatively affect the health of workers, harm the environment, lead to damage to expensive equipment and disruption of technological processes, and also cause non-compliance with environmental standards. Industrial emissions often contain not only dust, but also aggressive gases, aerosols and other harmful substances, which requires the use of various cleaning technologies; to combat corrosive components, for example, reliable frp scrubber manufacturers play a key role, supplying durable equipment. A particular danger in many processes is sparks that can occur during production and lead to fires and explosions in filtration systems.

Baghouses and the risk of ignition

Baghouses are one of the most common types of equipment for capturing dry dust in industry. They effectively clean large volumes of air from solid particles using a system of fabric or non-woven filter bags. However, many industrial processes where bag filters are used are associated with the risk of sparking. This is typical for metalworking (grinding, welding), woodworking, transportation and processing of bulk materials, as well as other operations where friction, impact or the presence of incandescent particles are possible. Even a single spark entering a bag filter where combustible dust accumulates can cause ignition of the filter elements, a fire or even a destructive explosion of the dust-air mixture. The consequences of such an incident, as well as the failure of other critical equipment, for example, an incorrectly selected pp frp scrubber system that cannot withstand chemical loads, can be catastrophic, leading to production shutdowns, significant material losses and a threat to personnel safety.

Spark arresters for bag filters – operational safety

Spark arresters prevent sparks from entering the filtration system, which could cause a fire or explosion. They are installed in the air duct in front of the bag filter and work according to different principles:

• Cyclone effect – changing the direction and speed of the flow separates heavy particles.
• Spark cooling – reducing the temperature to a safe level.
• Mechanical capture – nets or other elements trap sparks.

Using spark arresters:

• protects equipment and personnel;
• extends the service life of filters;
• minimizes the risk of accidents.

Scrubber systems – effective air purification

When bag filters cannot cope with gases, aerosols or wet dust, scrubbers are used. They purify the air by contact with a liquid that absorbs or neutralizes harmful impurities.

Advantages of wet scrubbers:

• effectively remove solid and gaseous pollutants;
• universal for difficult cleaning conditions;
• provide comprehensive air purification.

Scrubber materials: FRP and PP/FRP

For aggressive environments, corrosion-resistant materials are used:

• FRP (fiberglass) – chemically inert, strong, durable.
• PP/FRP – the inner part is made of polypropylene (resistant to chemicals), the outer part is made of fiberglass (reliability of the structure).

The choice of material depends on:

• the composition and concentration of pollutants;
• process temperature;
• characteristics of the working fluid.
