SPIRAL NOZZLE FOR HEAT-MASS-EXCHANGE PROCESSES AND FOR CHEMICAL PROCESSES COMBINED THEREWITH

摘要

The invention relates, mainly to the petroleum and chemical industries. The inventive spiral nozzle provided with unbounded module and unlimited coil number is arranged in a packet (the transport unit or a process structural space volume) in a parallel position with respect to each other and according to a dense location pattern. The adjacent and successive spirals can be embodied in the form of spirals having similar or mixed sense of rotation. The successive spirals can be optionally embodied in such a way that they are not coaxial, limited by angle turns of end faces and non-modifiable in terms of characteristics thereof. The inventive arrangement allows a passing flow to freely react to the spiral swirling action and to create the opposite or parallel transitional motion of the flows between the parallel spirals, thereby increasing the flow turbulisation, promoting the stabilisation of the sectional distribution of dispersed particles and to optimise the selection of a packet structural design for the particular conditions of a process.
