FIELD: machine building.SUBSTANCE: preformed packing for heat-and-mass exchange devices, mainly bioreaction ones, consists of a grid in the form of a coil section, is distinguished for the fact that the coil sections, at least two ones, are installed alternately depending on the coil winding density, the grid coil is of rectangular cross section and the distance between the turns is equal to from 2 to 20 thicknesses of the grid wall, a high-porous polymer gasket is installed inside the coil to form a biofilm.EFFECT: improved efficiency of heat-and-mass exchange processes.4 cl, 1 dwg |
