Wet air scrubbers for dust control

Wet air scrubbing is often overlooked as a method of air pollution control. The wet air scrubbing technology is not at the forefront of the engineers’ list of equipment for emission control due to the reluctance to change from the well known dry dust collectors. Despite the hesitance, wet air scrubbers are successfully installed downstream of furnaces, dryers, mixers, bucket elevators and other emission points. Wet air scrubbing is not only a versatile technology that can replace a traditional dry dust collector, but it is often the best option for dust control.

Some production processes result in a particulate matter that is combustible. In these cases, wet air scrubbers are an ideal choice as water eliminates the explosion potential of the dust. Moreover, wet scrubbers do not require design modifications as dry dust collectors do. The dust that is collected by a scrubber is immediately wetted and saturated with water, which eliminates the dust cloud – a necessary part for an explosion to happen. In addition, wet scrubbers eliminate the need for an isolation protection, making wet air scrubbing a safe and cost-efficient way of dust control for this type of application.

High temperatures do not need to be addressed during the design of a wet air scrubber; their inherent ability makes them a perfect solution for hot air scrubbing. Dry dust collectors need to be manufactured according to the specific needs of hot air scrubbing; they require expensive high-temperature filter bags. Meanwhile, the standard design of most wet air scrubbers can handle high temperatures without any special design considerations.

If the process has a moisture content in the gas stream, it can potentially plug the dry dust collectors. Wet air scrubbers can process these difficult conditions without any issues. Due to the use of water in the scrubber, the moist gas is easily introduced. The same conditions in a dry dust collector will lead to caking on the filter bags, plugging, and high differential pressures.

Wet air scrubbers are a logical choice for applications that result in both gaseous and particulate matter that needs to be removed. Dry dust collectors are not suited for gas scrubbing; a secondary piece of equipment needs to be installed in order to address the gaseous pollutants. We air scrubbers can collect both solids and gases, do not require any additional equipment and design modifications.

Besides their versatility, wet air scrubbers are also more cost-efficient. Often wet scrubbers have low capital cost, better energy savings, lower maintenance costs.

If you search for the best air treatment device to improve air quality, you can buy a high-tech completely new type of wet scrubber – a Multi-Vortex wet air scrubber produced by Redwood Technology.

Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.  If you have any questions or would like to purchase a multi-vortex wet air scrubber, please contact us at info@rdwd.tech
