Оптимізація процесу приготування бітумної емульсії на кавітаційній установці

Abstract

The construction of the experimental plant, the working principle of which is based on cavitation bituminous emulsion components processing, has been developed. In the plant the pressure at the cavitation dispergator input and the cavitator position relatively the diffuser part of the dispergator are regulated. The components and prepared emulsion temperatures are controlled. The pressure at the input and the output of the dispergator is fixed. Quadratic equations of regression are received with the help of multivariable experiment planning. These equations give an opportunity to determine dependences of dispersion values on the basic managed parameters of the bituminous emulsion making process: the pressure at the dispergator input, the cross sectional area of the dispergator bore and the components processing multiplicity. Parametric optimization of dispersion values has been conducted. The optimal parameters values of the bituminous emulsions preparation process have been obtained: S = 70 mm2 ; n = 7; p = 1,2 МPа and the minimum values of the optimization criterion D is 3 mkm. The surfaces of the optimization criterions responses and their two dimensional sections, which evidently illustrate the dependences of dispersion D values on separate parameters, have been plotted.
