<p>The hot gas treatment apparatus comprises a generally cylindrical chamber (1) of elongate form through which the gas is caused to flow. The chamber (1) has a gas inlet pipe (2) projecting into the chamber from which the gas flows towards a gas outlet (3). A pair of water pipes (4) conduct water coolant to opposite sides of the chamber (1) where it is sprayed into the gas flow by way of nozzles (5) directed at least partially towards the gas outlet (3). The water sprays (53) not only cool the gas, but also condense hydrocarbon impurities such as tars and oils, and collect solid particles from the gas. A mixture of the water, hydrocarbon condensate and solid particles therefore falls to the bottom side of the chamber (1) and then, due to the longitudinal axis (7) of the chamber being inclined to the horizontal at about 10°, the mixture flows down to a drain (6) at the outlet end (31) of the chamber, from which it leaves the chamber. Each spray (53) is in the form of a thin, curtain-like water film which extends to the opposite side of the chamber (1). The films are not directed perpendicularly to the cylinder axis (7), but are angled slightly towards the outlet end (31) of the chamber, so as to intersect the axis (7) at about 80°.</p> |
