Abstract

Device for putting in contact fluids appearing in the form of different phases at least one of which is in hot and gaseous form comprising an outer envelope of revolution (1) provided in its upper part with an upper floor (2) and in its lower part with a convergent-divergent nozzle (5) defining a narrow passage (6) in which the hot, gas phase circulates driven with a helical movement. The downstream end of a feed pipe (7) of one of the other phases appearing in the liquid or pasty state or in the form of a suspension comes out axially. To release all the thermal stresses of the envelope (1) and of the upper floor (2) and to maintain the downstream end of the feed pipe (7) in its initial adjustment position in relation to the axis and to the plane of the narrow passage (6), the upstream end of the feed pipe is separated from the outer envelope of revolution (1) by an elastic, fluidtight means able to absorb expansions due to the differences of temperature between the feed (7) and the pipe and envelope (1).
