Impinjet® Wet Scrubbers
High Absorption Efficiency for Gases and Vapors.
Sly Impinjet® Wet Gas Scrubbers
Sly Impinjet® Wet Gas Scrubbers collect particulates and absorb vapors and gases. Low water consumption and minimum pressure drop achieve high collection efficiencies (99% @5 microns). This is the most efficient low-energy scrubber available—capacities to 200,000+ CFM.
Constructed in either metal or plastic, each scrubber stage acts as a discrete fractional collector. Often referred to as “plate scrubbers or tray scrubbers,” the Impinjet units are available in multiple-stage designs to maximize efficiencies. Highly resistant to fouling, the Impinjet Wet Scrubber is ideal for applications requiring condensing and particulate removal.
Water requirements are typically 3 GPM per 1000 ACFM. Impinjet® Scrubbers furnish unique flexibility. With the future in mind, additional stages can be added to existing installations to improve efficiency and handle tomorrow’s requirements without increasing liquid consumption. There is no need to buy complete new units.

Features & Benefits
- 99% collection efficiency for 5 microns or larger.
- Optimal performance for cooling, condensing and heat recovery for applications with hot flue gases.
- High absorption efficiency for gases and vapors. Experts agree that impingement plate towers have the ability to remove gaseous pollutants to any desired concentration if a sufficient number of plates are used. This means high mass transfer rates can be achieved.
- These high efficiencies are achieved at a low pressure drop.
- No moving parts to maintain.
- Needs less scrubbing fluid than most other scrubbers.
- Integral sump or separate recirculation system designs available to minimize total water consumption.
- Can handle high temperatures and temperature fluctuations.
Options
- Easily adjustable throat permits setting pressure for maximum efficiency. Can be fine-tuned to application while scrubber is running. Throat Damper blased are readily replaceable.
- Variable-spin damper in separator maintains proper velocity for collection of fine droplets.
- Removable scrubbing liquid piping- no nozzles to wear or plug.
- Access door permits inspection of flooded elbow and spin damper.
- Simple open design has low potential for buildup and pluggage.
- Temperature and corrosion resistant construction is available.
- Can employ a high concentration slurry as scrubbing liquid
Impingement Scrubber Operating Principles
The gas passes up through the openings in the perforated plates (trays) that hold a bed of liquid. The secret is in the scrubber’s design, which uses an impingement baffle above each individual hole. The tiny droplets created by the wetted baffles are the heart of the collection process.
Gas velocities of 60 to 75 feet/second through the holes result in thousands of jets, which atomize the liquid into droplets 100 microns in diameter to clean the contaminated gas. This entraps the particles in the scrubbing liquid. Each jet aspirates liquid from the blanket of scrubbing fluid and results in a wetted target surface on the baffle, which is located just above the point of maximum velocity (vena contracta).
In operation, the scrubber is highly pluggage-resistant. The continuous violent agitation of the blanket of scrubbing fluid prevents settling of particles and flushes them away. Intimate gas/liquid contact results in the maximum collection efficiency for particles and droplets as well as absorption (mass transfer) of gases and vapors. When used for absorption, low outlet emissions can be achieved by virtue of the scrubber’s countercurrent operation. The Sly Impinjet® Gas Scrubber is able to reduce gaseous pollutants to any desired concentration if a sufficient number of plate stages is used.
