A wet scrubber is an efficient method of removing particles and chemicals from industrial exhaust fumes. Wet scrubbers are more complex than dry dust collection systems, because they gather pollutants from the exhaust stream using water or a water-based solution.
What are the benefits of using a wet scrubber?
· They handle flammable dust with caution
A wet scrubber totally avoids the risk of an explosion in the scrubber in applications, involving combustible particles. The risk is determined by the type of dust, the size of the particles, the temperature, and the concentration.
Managers must consider the potential implications of a workplace mishap, such as fines, lawsuits, and medical expenditures, against the higher cost of a wet scrubber. A wet system is the only method to entirely eliminate the risk.
Remember that dry system that handles flammable dust are required to have safety devices, which raises the system's cost. The expense of continuous maintenance should be considered in the risk-benefit analysis, because poor maintenance is a major factor in dust-related explosions.
· It conserves space
Wet scrubbers take up less room in the facility. Wet scrubbers have a smaller footprint than baghouses and cartridge collectors, with related ductwork. When it comes to facility space, size is everything.
· It handles abrasives or sticky dust
There are no filters to change in wet scrubbers. Another factor to consider is abrasion. Dust collectors, conveyors, and rotary valves can all suffer from excessive wear, from abrasive particles, reducing their service life.
· Unwanted soluble gases are eliminated
When gas and water are forced together in wet scrubbers, the gas flows through the water, leaving the particle behind. Soluble gases, on the other hand, do not flow through but rather absorb into the water, allowing them to be removed from the waste stream.
Chlorine, ammonia, and hydrochloric acid are examples of waste gases that are often eliminated, from industrial operations. Water-soluble scents are also removed using wet scrubbers. Dry dust collecting systems, on the other hand, do not eliminate gases or odours.
· Fine particulates and mists are removed
Wet scrubbers are exceptionally effective, eliminating up to 99% of particles, including those too tiny to be captured by baghouse and cartridge filters. Scrubbers with ultra-fine droplets capture and hold microscopic particles, in the fluid for removal. Because, mists can entrain small particles, a wet scrubber will perform when a dry dust collection device cannot.
· It reduces upkeep
A wet scrubber requires very little upkeep. The only thing that needs to be done on a regular basis is to change the scrubber water. The process water should be changed as needed to achieve pollution control goals.
The frequency of maintenance will be determined by the system's CFM, the amount of particles in the influent gas, and the PPM targets for the effluent gas.
While, there is more engineering complexity, wet scrubbers often have lower running costs than dry systems, and they may also have equivalent or lower upfront expenditures.
Furthermore, in many cases, a wet scrubber is the sole technique capable of achieving the desired outcomes. That is why, company executives choosing a wet scrubber should understand the benefits and drawbacks of wet scrubbers, and how they apply to their specific applications.
