FIELD: process engineering. ^ SUBSTANCE: proposed method comprises gathering major and dust-like dirt into container, washing off soluble dirt by water, mechanical breaking of water insoluble dirt, collecting water with dirt into container and moving said container to cleaning equipment. Prior to covering cleaning, initial concentration of dirt, Cini, is determined (mg/l or g/m3), along with cleaning efficiency, E, in a cleaning cycle (%) and residual concentration of dirt, Cres, after one cleaning cycle (mg/l or g/m3). To provide for rated residual dirt concentration, Cres (mg/l or g/m3), cleaning is performed several times, the number of cleanings, n, is determined from the formula n=logba, where b=1-0.01E, a= Cres: Cini, note that n=log1-0.01E (Cres: Cini). ^ EFFECT: simplified method. ^ 4 cl |
