FIELD: reaction systems. SUBSTANCE: invention can be used for minimization of recombination processes leading to neutralization and transformation of charged biologically-and-chemically-active particles by imparting laminar flow mode to air flow at which moving of air takes place as in form of thick layers parallel to direction of flow when interpenetration of molecules in flow occurs owing to molecular diffusion. Damping elements are made in form of three- dimensional and/or flat figures, and summary length of contacts of housing and damping element with air flow in I-th cross section of air duct on section of mounting of damping elements is not less than (Lc)i+(Ld)i>k(S)i where (Lc)i is summary length of lines of contacts of air duct housing with air flow in I-th cross section of air duct on section of mounting of damping elements, m; (Ld)i is summary length of lines of contacts of damping elements with air flow in I-th cross section of air duct on section of mounting of damping elements, m; (S)i is are of air flow in I-th cross section of air duct, sq. m; k is proportionally factor taking into account kinetic and kinematic characteristics of air flow where U is preset process velocity of air in air duct, m/s; nu is kinematic viscosity factor of air in air duct sq.m/s; Re is Reynolds number. EFFECT: provision of possibility of varying kinetic energy of flow used in technological purposes at preservation of its laminary structure. 1 dwg
