ADSORBER Russian patent published in 2012 - IPC B01D53/00 

FIELD: process engineering.

SUBSTANCE: invention relates to gas cleaning by adsorbents, particularly, to gas cleaning equipment and may be used in chemical industry, metallurgy, etc, for gas cleaning. Adsorber comprises vertical casing divided by perforated vertical zigzag-like webs into sections to make alternating staggered confusers and diffusers, top and bottom grate, and gas feed and discharge branch pipes. Gas feed branch pipe is shaped to converging truncated cone made from resilient material with helical lengthwise grooves made on its inner surface. Note here that said grooves represent a dovetail structure. Discharge openings are arranged regularly between aforesaid helical grooves in longitudinal direction from gas feed branch pipe larger base to its smaller base. Gas feed branch pipe smaller base is plugged by resilient material. Gas discharge branch pipe inner surface is provided with helical lengthwise grooves with their tangent line directed clockwise. While gas feed branch pipe inner surface is provided with helical lengthwise grooves with their tangent line directed counter clockwise.

EFFECT: stabilised gas flow at discharge branch pipe outlet.
