MODERNIZATION OF DEVICES FOR PURIFICATION OF AIR FROM SOLID HIGH-DISPERSED AEROSOLS

A device for cleaning solid particles with a dispersion of 0.1 μm is proposed. The principle of the apparatus is based on coagulation of particles on slots perforated in the form of slots, using irrigation of contaminated air with water through nozzles with a dispersed composition from 2.0 microns to 10 microns. When a threephase fl ow passes through the slots of the fi rst separator plate, turbulent coagulation occurs due to turbulence of the fl ow in streams with a small turbulence scale, which leads to particle coarsening. When the jet runs onto the second plate, a boundary layer is formed that has an increased viscosity to the components of the jet. Viscosity is formed due to the sedimentation and mixing of water particles and dust (including coarsened) on the surface of the second plate, where particles are mainly deposited. The dependences of the apparatus effi ciency on the width of the slots and their mutual arrangement on the fi rst and second plates, the combination of which provides a mode of increased coagulation and high effi - ciency of particle capture by the apparatus, are revealed.
