Wet Air Scrubbers: Benefits and Applications

Wet Air Scrubbers: Benefits and ApplicationsThe issue of dust emissions from sugar factories is not as severe as it was ten years ago. One of the main reasons for such positive changes is the increased use of wet air scrubbers for removing dust from boiler flue gas.

A wet air scrubber offers numerous benefits. A significant and highly advantageous benefit of the scrubbers is their ability to stop various pollutants from being released into the air via the exhaust gases. In comparison with other air pollution control devices, scrubbers are very multifunctional. They can remove solids, mists, and gases simultaneously while providing cooling. Scrubbers are also capable of handling explosive and flammable gases safely. Scrubbers are quite resilient and appropriate for functioning in nearly any environment since they can endure a broad spectrum of temperatures. Wet scrubbers can effectively eliminate pollutants ranging from mercury to acidic gases responsible for acid rain.

Regarding finances, wet air scrubbers incur lower initial capital and maintenance expenses while providing greater energy savings. Technological studies and innovations show that scrubbers are often one of the cheapest SO2 control options to install and operate, particularly when revenue from byproducts and emission allowances are considered. The newest developments of the scrubbers allow reducing the costs by more than 30%. Additionally, wet air scrubbers contain no internal moving components. They may be less expensive to purchase and operate than any other dust collector even with the added cost of replacement filter bags for a baghouse.

Despite the effectiveness of scrubbers, there are still operational problems with factory crushing rates. This is due to the fact that many wet scrubber installations reduce boiler steam output. Firstly, it happens due to blockages that increase the pressure drop across the scrubbers. Secondly, droplet carryover reduces collection efficiency and causes build-up on and wear of the boiler.

The need to improve the structure of scrubbers motivated further developments in this field. To improve understanding of the flow processes occurring in a wet air scrubber and to evaluate the options for improving their characteristics, the modeling and experiment were applied. Results of this research project include the extended modeling capability with the updated code, the computational fluid dynamics (CFD) modeling and flow visualization result, the scrubber design changes, and the test rig and scrubber scale model. These findings suggest a resurgence in the popularity of scrubbers: applying the suggested modifications is expected to enhance factory output and decrease emissions from sugar factory boilers.

Multi-vortex wet air scrubber is a new type of wet scrubber, which has a lot of advantages in comparison to conventional wet scrubbers. Multi-vortex wet air scrubber is more compact, economical and eco-friendly than other types of wet air scrubbers. Multi-vortex wet air scrubber produces the cleaning mist differently from other scrubber systems, which results in running costs that are much lower than for a common wet air scrubber. Multi-vortex wet air scrubber cleans air from gases, dust, vapors and other admixtures using water or other cleaning liquid. Multi-vortex wet air scrubber is the new type of wet air scrubber that saves water.
