Washed activated charcoal adsorbers

Abstract

Abstract This disclosure relates to activated charcoal adsorbers for low head room applications (short height) sealed so that there is no possibility of bypassing from upstream to downstream, and fitted so that the charcoal bed can be washed with water or other fluid at right angles to the air flow. The washing is generally done as a separate operation with the air flow shut off and is for the purpose of removing acid or alkali material to minimize corrosion, removal of chemical breakdown products, or the removal of an adsorbed substance to recover it or to regenerate the charcoal so that it can be used again in adsorption service. The charging of the charcoal is done at the top and also the sprays are arranged at the top so that they can be observed, adjusted, or changed. Removal of the top cover gives ready access to the top of the charcoal cell and the sprays, permits observation of the performance of the purification system, and permits the adding of charcoal as may be needed, and the servicing of the sprays. The amount of liquid flow can be measured at the point of addition or as the liquid drains from the bottom of the adsorber.
