Leading Air Pollution Scrubber Manufacturers

Scrubbers are quite diverse in contrast to other air pollution management systems, having the capacity to remove particulates, mists, and gasses while also providing cooling. They can also safely handle explosive and flammable gasses. Scrubbers, on the other hand, are prone to corrosion and create slurry waste streams that are difficult to recycle and remove.

Types of Air Scrubbers

Scrubbers come in various shapes and sizes, each with its function and effectiveness.

1. Spray Towers

   Gas streams are pumped into a chamber and interact with cleansing liquid created by spray nozzles in spray towers or spray partitions. Spray towers have a low power usage but poor particle collecting efficiency.

2. Cyclone Spray Chambers

   These scrubbers combine the cyclone and spray tower capture systems. Gas streams usually enter the chamber at high speeds, tangentially.

3. Venturi Scrubbers

   Scrubbers with a venturi-shaped chamber with converging and diverging parts are known as venturi scrubbers. Water is pumped at low pressure into the venturi's throat, where the gas stream travels at high speeds.

4. Orifice Scrubbers

   These are comparable to venturi scrubbers. Before entering the aperture, the gas passes through pools of cleaning liquid at high speeds. Droplets and contaminants are eliminated as it escapes by colliding with a series of baffles.

5. Impingement/Perforated Plate Scrubbers

   Impingement/Perforated Plate Scrubbers are a type of orifice scrubber. Gas streams enter the device from the bottom and travel through a perforated tray that contains or is sprayed with a layer of liquid.

6. Packed Bed Scrubbers

   These scrubbers, predominantly gas absorbers, are the most effective for treating gas streams containing gaseous contaminants.

7. Dry Scrubbers

   Dry scrubbers utilize no liquids to remove pollutants from exhaust gasses. They use a dry reaction substance called sorbent, such as alkaline slurry, to remove acid from gas by passing the gas through the sorbent dust to optimize binding.

8. Wet Scrubbers

   They are effective air pollution control devices that remove particles or gasses from industrial exhaust streams. A wet scrubber works by putting a scouring liquid into the filthy gas stream, which collects the particles or gasses.

Working of Air Scrubbers

1. Scrubbers are pollution-capturing and removal machines that employ a liquid (usually water).
2. A cleaning liquid is atomized and distributed into the gas stream through a nozzle or opening.
3. Agglomeration, adhesion, or encapsulation causes the droplets to entrain and collect dust particles.
4. As a result, the particle size and mass are effectively increased, making them simpler to collect in a following filter or separation operation.
5. The scrubbing liquid absorbs and neutralizes gaseous contaminants simultaneously.
6. The suspended liquid is usually collected and circulated through the system using mist collectors.

Applications of Air Scrubbers

• High Productivity Dry scrubbers are indicated for applications such as nitric, hydrochloric, sulfuric, and chromic acid, which require little water.
• Flue-gas condensation can recover heat from hot gasses in scrubbers.
• They're also employed in solar, PV, and LED applications requiring large fluxes.
• Dry scrubbers are typically used to remove acids from gasses.
• Wet scrubbers are used in various industrial settings, including pollution reduction in food processing plants and petroleum refineries.

Benefits of Air Pollution Scrubbers

• Air pollution scrubbers have low-risk handling of flammable and explosive dust.
• A single unit absorbs gas and collects dust.
• Air scrubbers allow hot gasses to cool down.
• Corrosive gasses and dust can be neutralized.
• They are compact and can typically be adapted into existing collecting systems.
• Venturi scrubbers are easy to install and maintain and have a high collecting efficiency for particle pollutants.
• Cyclone spray chambers are cost-effective and need little liquid.

Choosing the Best Air Pollution Scrubber

These are the most critical criteria for an industrial buyer to consider when choosing a scrubber for their application.

• Airflow - The allowable gas stream flow rate or range of flow rates through the scrubber is defined by airflow, measured in cubic feet per minute.

• Liquid - Refers to the scrubber liquid's planned flow rate, usually expressed in gallons per minute. It controls how much water the scrubber uses, significantly influencing the system's operational expenses.

• Minimum Particle Size - The least diameter of particulate matter that a dust collector can capture, measured in micrometers. This rating effectively defines the capabilities of the collection equipment.

• Capture Rate - The proportion of particle matter or gaseous pollutants in the scrubber's filtered gas stream is efficiently removed.

• In addition to performance criteria, material compatibility and operating temperature are two more factors to consider when selecting the best air pollution scrubber.

• Material compatibility – It's critical that the materials employed in the scrubber's construction be compatible with the gas stream's chemical and physical qualities.

• Operating temperature – Scrubbers are built to cool or quench hot gas streams; they are limited to a particular temperature range, beyond or below which they may not function efficiently.
