Analysis and solution for nozzle blockage in desliming screens of coal preparation plant
Taking the Hei Black Dai Gou coal selection plant as an example,the on-site circulating water treatment process was analyzed,and the simulation software was used to simulate the fluid flow inside the spray nozzle pipe to further verify the blockage location of the spray nozzle and the pressure change inside the pipe during blockage.Based on the analysis of the blockage causes,suggestions were made for the transformation of the on-site circulating water system.By preventing blockage,detecting blockage and solving blockage,the particles mixed in the circulating water are eliminated,which is used to solve the problem of frequent blockage of the deashing spray nozzle.By solving the blockage problem of the spray nozzle,the deashing efficiency of the deashing screen will be improved,the consumption of the medium will be reduced,the extra workload of the site workers due to the pipe dredging will be avoided,and the intelligent construction of the coal selection plant will be promoted.
