Dust often presents a major challenge in various industries: coal dust in the atmosphere at loading docks, asphalt dust during concrete production, considerable iron ore dust at mining locations, sugar dust, and comparable substances. Sugar dust is a major challenge for the sugar industry, resulting in substantial revenue losses as the end product becomes sugar dust. Sugar particles in the air lead to a layer of sugar granules on various surfaces that can interfere with the production process.

Dry dust collectors, such as baghouse filters and cartridge filters, are the common way of removing dry sugar dust from the air. However, these systems are not ideal for sugar dust scrubbing and have numerous disadvantages.

Dry particles in the atmosphere heighten the danger of fire since they serve as fuel for an explosion. Other elements necessary for an explosion are an enclosure, dispersion, oxygen, and an ignition source. The ignition source can come from a production process as a spark, from construction activities like welding or grinding sparks, or from an inattentive worker smoking a cigarette; the other elements exist within the dry dust collector. The environment inside the baghouse or cartridge filters creates the perfect conditions for the combustion to occur. Sugar dust carries a static charge and can arc inside the air chamber, which causes ignition.

Explosions caused by sugar dust in the air are not rare – they occur often enough for government regulations to be broadened.

Wet scrubbers can overcome all the disadvantages of traditional dry dust collectors (explosion potential, high temperatures, moisture in the gas stream).  They do not create the environment in which combustion might occur; wet scrubbers can handle high temperatures of inlet gas stream.

Most wet air scrubbers suffer from clogging due to the sludge that is created after the sugar dust mixes with water. This mixture is very sticky, it causes build-up inside the chamber and stops the scrubbing process. Multi-vortex wet air scrubber can process sugar dust without being clogged due to the high speeds of microturbulence vortices that are used to scrub the inlet gas. Tests show that a multi-vortex wet air scrubber can handle 250 g. of sugar per 1 liter of water without any issues.

Over the past years, several sugar dust explosions have happened at sugar producing and storing facilities. Sugar dust induces explosions can be very dangerous and cause significant damage to both the facility and personnel.

Dry dust collectors are not appropriate for sugar dust as they get clogged easily by sugar. Moreover, dry dust collectors create a perfect environment for sugar dust combustion, as dust accumulates in high concentrations in an enclosed space. Wet air scrubbers are effective against dust and don’t create an environment that poses a threat of sugar dust explosion.

A new type of wet air scrubber, multi-vortex wet air scrubber provides improved air treatment quality and can be used for both particle matter and gas collection. The treatment quality of multi-vortex wet air scrubber is generally 99.95-99.99% for both types of pollutants. Besides high efficiency, multi-vortex wet air scrubber possesses several advantages over conventional wet scrubbers – multi-vortex wet air scrubbers are compact, omnivorous, eco-friendly, economical, and low-maintenance.
