ABSTRACT:
A panel bed fitted for puffback cleaning is arranged so that gas entry faces of the granular material in the panel bed can be wetted by a liquid. Efficiency of treatment of a gas for removal of particulate matter by filtration is improved, especially for fine particulate matter at low loading in the gas, and advantageously with use of relatively coarse granular filtration medium. The liquid may be vaporized by the gas, leaving solid dissolved or suspended in the liquid to accrete upon the granular material of the bed. The panel bed is useful for removing sulfur dioxide from combustion products by absorption by a liquid absorbent, such as a suspension of slaked lime particles in water.
