Abstract: The invention relates to methods and devices for spraying liquid during production processes requiring a uniform dispersion mixture, in particular in internal combustion engines requiring a fine fuel-air mixture, in the chemical industry for apparatuses for rinsing gas with liquid, which require a uniform coarse-dispersion mixture for reducing the drop entrainment of a rinsing liquid. The inventive method consists in collecting, during the liquid spraying, which is carried out by injecting a liquid at an angle to a gas flow, particles in those sectors of the spray cone that are appropriate to particles of specified sizes. The liquid spraying and collecting processes are carried out at one section of a laminar unidirectional gas flow. The collected particles form, when accumulated, a liquid that is returned for re-spraying.
