摘要：
liquid ultraviolet ray processing method with controlled film thickness in installations for processing the liquid in a thin layer, comprising forming a thin layer and further processing it by radiation, characterized in that in the treated liquid product is exposed to ultraviolet radiation in the range of 200 ... 400 nm, wherein the liquid flow rate within the vertical operating cylinder formed film thickness δ, the value of which is determined by sootnosheniyuiliδ≤δ = 2.3 / μ, where δ- maximum film thickness, m δ - film thickness m μ - absorption liquid emissivity, m H- minimum value of irradiation dose, J / m H- maximum irradiation dose, J / m H- maximum allowable irradiation dose, J / m for that regulate fluid flow within the vertical operating cylinder, and the film thickness and the flow rate is determined from sootnosheniyagde G - fluid flow, kg / s δ- maximum film thickness, m δ - film thickness m D - diameter of the cylinder, m ρ - density of the liquid product, kg / m ζ - dynamic viscosity, kg / (s * m), wherein the maximum irradiation dose sootnosheniyagde δ- determined from the maximum film thickness, m δ - film thickness m H- minimum value of irradiation dose, J / m, and if a limit is set for the specific irradiation dose of liquid product H, then operate the condition H
