Ryzhkov O. Enhancing of gas-cleaning devices of power plants on the basis of hydrodynamic processes modeling

The generalized scheme of a complex gases clearing intensification from highly-dispersible and rough-dispersible particles is developed by hydrodynamic methods. For numerical expression of theoretical calculations the factor of hydrodynamic efficiency displaying the general level of useful work of gas-cleaning devices for the first time is entered. The factor is offered for using for characteristic numerical expression of theoretical calculations of a stream of gas in a flowing part of gas-cleaning device. It is offered to consider highly effective of gas-cleaning device with calculations the factor of hydrodynamic efficiency over 85 %. The new universal test bench is developed for researches of gas purifiers in the form of a pressure head wind tunnel of the open type, allowing to conduct researches in a wide interval of possible expenses of the diphase environment and concentration of a disperse phase. On the basis of the developed technique and the executed theoretical calculations it is developed dimension-type a number of gas purifiers for catching of oil aerosols of systems prompt GTE and ventilation systems crank case. Researches of oil separators at the experimental stand have shown that the factor of total efficiency exceeds 99.99 %. Aerodynamic resistance - from 1.0 to 5.0 кPа.
