【 摘 要 】

Studies have been conducted relating to a priority area-the sustainable use of natural resources, based on the suggested design arrangement of the operating module, with counter-current motion of washing liquid in the system of a distributed wash. The assignment of permittable concentrations of chemical compounds to be washed-off on elements as well in wash tanks is suggested. Regularities as to the change of electrolyte concentration on element surface and in distributed wash system are established. Results are presented of numeric calculations of the spray rinse process of the elements having blind and threaded holes filled with liquid impurities. Spray rinse of elements with blind holes, and blind threaded holes are compared. Substantiation of jet velocity and recommendations as to the minimal diameter of the washing of thread holes which ensures efficient removal of scum, is carried out. The studies make exposure of components at spray rinse more specific. The technique for assignment of cross-feed of parts towards multi-nozzle heads which ensures effective scum removal was substantiated.
