Wet Dust Collectors & Scrubbers:

Wet dust collectors and wet scrubber systems are often used where there are concerns of fire and/or explosion.

While they are typically provided for these applications, they can also be used in many other applications as well, including sticky materials.

By introducing a deluge of water to a dirty airstream, contaminant is extinguished, saturated and made heavier creating what is commonly referred to as “sludge”. Immediately beyond the water deluge is a separator using centrifugal force, or baffled channels, to separate the clean air from the sludge.  

The clean air continues on through the system while the sludge drops out to a filter bed where it is drained leaving a disposable byproduct. The contaminated water is then recirculated to the initial stage to continue the process or drained to a waste water treatment system.

Systems can be supplied with fresh water discharging to a water treatment system or provided with a recirculation water system that has a steady but minimal flow of fresh water.  

Wet collection cleaning efficiencies vary widely based on the style, airflow and water flow rate but can be as high as 99.9+%. In most cases the cartridges clean to a level of 99.9+% on dust with a particulate size of 0.5 microns or more.

Regardless of the configuration, these collectors are carry a significantly smaller footprint and height than comparable baghouses making them easier to locate and maintain. Routine maintenance times are significantly reduced due to the accessibility of the filters.

Compared to other collector options, the housing is much smaller requiring less labor and materials making for a less expensive collector.

What is a Wet Scrubber?

An industrial wet scrubber is a type of air pollution control equipment that uses water or other liquid to remove dust particles and other pollutants from a gas stream.

The gas stream is passed through a chamber where it comes into contact with the liquid, which captures the pollutants and removes them from the air.

Wet scrubbers are better than other types of dust collection equipment in a number of ways. For example, they are very good at catching fine dust particles and can hold a lot of dust.

They also have the added benefit of being able to neutralize any acidic gases present in the air stream.

It’s important to remember that making and using an industrial wet scrubber to collect dust is a complicated process that requires a lot of knowledge and skill.

Talking to a reputable wet scrubber supplier is important to make sure that the system is designed and installed correctly to meet the needs of the application.

What are the benefits of wet dust collection systems?

Wet dust collectors have several advantages over dry dust collectors:

  1. High efficiency: They are more effective at capturing fine dust particles and volatile organic compounds (VOCs) than dry dust collectors.
  2. Lower fire risk: The water or other liquid used in wet dust collectors helps to suppress dust explosions and fire hazards, which is a major concern in certain industrial settings.
  3. Versatility: Wet dust collectors can be used for a wide range of applications and industries, including miner applications, coal tripper rooms, and civil tunneling applications.
  4. Low energy consumption: Some wet dust collectors use less energy than dry dust collectors, especially electrostatic precipitators.
  5. Longer filter life: The water or other liquid used in wet dust collectors can help extend the life of the filter media by trapping dust particles and preventing them from clogging the filter.

What are the drawbacks of wet dust collectors?

Wet dust collectors have several potential drawbacks:

  1. Maintenance: They require regular maintenance, such as cleaning or replacing the filter media and the liquid solution used to trap the dust.
  2. Complexity: They are generally more complex and difficult to operate than dry dust collectors, requiring specialized training for maintenance personnel.
  3. Environmental impact: The liquid solution used in wet dust collectors can be toxic and may require special disposal methods.
  4. Corrosion: The liquid solution used in wet dust collectors can cause corrosion in the equipment and ductwork, which can lead to leaks and other problems.
  5. Moisture: The use of water in wet dust collectors can cause additional moisture in the air, which can be problematic in certain environments and applications.

Even though wet dust collectors have these drawbacks, they are still preferred in some industrial settings because they are better at capturing fine dust particles.

Common Wet Dust Collector Applications:

The best way to get rid of fine dust particles and volatile organic compounds (VOCs) from the air is with a wet dust collector. 

They use water or another liquid to trap the dust, which makes them more effective at capturing smaller particles than dry dust collectors. 

Wet dust collectors are often used in places like schools, hospitals, and office buildings, as well as in industries like woodworking, metalworking, and making chemicals.

  • Metal Grinding
  • Flour Dust
  • Pharmaceutical
  • Chemical Manufacturing

What’s the difference between a scrubber and a wet dust collector?

A scrubber and a wet dust collector are both types of air pollution control equipment, but they have different functions and uses:

  1. A scrubber is a device that uses a liquid or a mist to remove pollutants from a gas stream, such as sulfur dioxide, hydrochloric acid and particulate matter, before the gas is released into the atmosphere. Scrubbers are commonly used in industrial settings, such as power plants and chemical manufacturing facilities, to reduce emissions of pollutants.
  2. A wet dust collector, on the other hand, is a device that uses a liquid or a mist to capture and remove dust particles from the air. Unlike scrubbers, wet dust collectors are not specifically designed to remove pollutants from a gas stream, but rather to capture dust particles before they are released into the air. They are commonly used in industries such as woodworking, metalworking, and chemical manufacturing, as well as in commercial and industrial settings such as schools, hospitals, and office buildings.

In summary, a scrubber is designed to remove pollutants from a gas stream, while a wet dust collector is designed to capture and remove dust particles from the air.
