A high velocity absorber has a lower larger diameter tank section for receiving a slurry at a liquid level in the. tank section, an upper smaller diameter absorber section where liquid scrubbing agent is mingled with flue gas from which impurities are to be absorbed, and a low pressure drop inlet assembly having a transition structure between the tank section and the absorber section for closing a gas flow path and a liquid flow path between the tank section and the absorber section. An inlet housing is connected to and communicates with the transition structure for inlet of flue gas into the transition structure between the tank section and the absorber section.

Low pressure drop inlet design to promote good gas flow patterns in high velocity absorbers

A low pressure drop inlet arrangement for an absorber having straight walls has a perforated tray positioned above the gas inlet opening between the walls of the absorber. A ring around the outer edge of the tray lacks perforations, or the perforations are covered. A drip ledge may be positioned on the bottom of the tray around the inner edge of the non-perforated ring. Baffles are positioned over the tray as well. The baffles may extend between the walls of the absorber, or they may only occupy the space over the perforations in the tray and the size of the tray perforations may be varied to control the overall pressure drop. An absorber made in accordance with the invention experiences a low pressure drop at the gas inlet opening.
