Rotary scrubber operates as follows. The contaminated gas is tangentially fed into the lower part of the scrubber, passing section of the guide vanes.

Water for irrigation is fed countercurrent above the vanes, thus creating turbulence, which greatly increases the surface mass transfer and convective diffusion. Thus made high efficiency particulate irrigating fluid.

Rotary scrubber is applicable for highly efficient purification of gas emissions of large volumes containing both low and high concentrations of particulate matter and gaseous pollutants. It does not clog, has low maintenance cost.

Advantages:

  1. Stable operation by the gas flow fluctuations and the contaminant concentration

  2. High separation efficiency

  3. Steady work with abrasive dust

  4. Low hydraulic resistance

Scope of application:

  • Cleaning and deodorizing of chemical and petrochemical enterprises, metallurgy, mining, waste incineration, food and other related industries emissions

Scheme of acidic emissions purification


Offered by our company centrifugal scrubber design features and principle of operation:

Intensification of mass transfer (increasing efficiency of gas purification) without hydraulic resistance increasing

Design and internal structure of the centrifugal scrubber provides intensive interaction of the gas and liquid phases in the volume, which is achieved by increasing the circumferential speed of the gas stream, and contact time of gas-liquid flows. The linear velocity of the gas flow increases, which does not increase the hydraulic resistance of the scrubber (the resistance is not more than 1.5 kPa)

Passive contact elements absence (packing, plates, etc.), leading to the scrubber free cross section clogging

High efficiency gas purification (over 99 %) is achieved through the creation of local zones of highly turbulent regime without increasing the hydraulic resistance of the scrubber. The required surface mass transfer is not due to passive surfaces, and fragmentation of a gas stream scrubbing liquid and a General intensification of their interaction through the organization of the guaranteed contact of the entire volume flow
