Patent ID: 7222841

Claim:
A gas and heat exchange apparatus comprising three substantially vertical elongate hollow members, the hollow members being connected by connecting members disposed at each end of the hollow tubular members, the connecting members adapted to join the three hollow members to each other in a substantially fluid tight manner, the connecting member at the upper end of the hollow members having an elbow joint at each end of the connecting member and a third, T-shaped joint between the elbow joints, the T-shaped joint having a crosspiece and a downcomer, each elbow joint attached to a first and second hollow member respectively and the downcomer of the T-shaped joint attached to a third hollow member, each elbow joint connected to either side of the crosspiece of the T-shaped member via a length of connecting member, a plurality of internal members spaced inside each of the hollow members, each internal member having at least one opening through which at least one fluid may flow, means for gas intake and exhaust in fluid connection with the hollow members, means for draining the hollow members and a means for adding liquid to the upper end of the hollow members, wherein each internal member is substantially disc-shaped with an outer edge and the outer edges of each internal member are in substantially fluid tight connection with an internal surface of the hollow member in which they are located.
