Problems of purification intensification of power plants in multiphase dispersed media and methods of their solution

Abstract

The scientfc and technical problems of the power plants improvement have been systematzed. The urgency of the problem of the power plants purifcaton in the multphase dispersed media is proved. The main purifcaton methods are analyzed, and previously unstudied pieces of problem of these processes intensifcaton are identfed. The task for the calculatons of the scheme of complex intensifcaton of the ultraturbophoretc transferal within the combined (internal and external) problem is set. The unstructured grid technology for the theoretcal calculatons of the pulsaton ultrasonic partcles depositon in the multpurpose grid coagulator is suggested and implemented. The aim of work is to develop the directons of the purifcaton intensifcaton of the dispersed multphase fows on the basis of the study results analysis. These directons are to be developed to design the technical equipment which ensures the intensifcaton of energy conservaton and environmental cleanliness of the power plants. The processes of the transferal of the fnely-dispersed phase by means of the ultrasonic and turbophoretc powers in the two-phase gas media of the power plants are the subject of the study. The scheme of complex intensifcaton of the ultraturbophoretc transferal of the micropartcles of partcles is developed within the «the inital fow secton – ultraturbophoretc grid coagulator» purifcaton system on the basis of the performed analysis of physical and mathematcal model of the process. The principles of intensifcaton of the ultraturbophoretc transferal and fnely-dispersed partcles depositon are developed. These principles are reduced to the usage of the energy potental of the dispersed two-phase media to depose the partcles; to the creaton of the acoustc vibratons gradients in the wall-adjacent areas at the surface of the channels and in the fow volume; to the generaton of turbulent pulsatons by the bodies of depositon of the multfunctonal purpose.
