Abstract
The scheme and algorithm of automated control over the modes of operation of electric adsorption mass transfer devices for selective purification of gas emissions are presented on the example of a continuous electric adsorber with a moving bed of adsorbent. The principle of automated control consists in self-adaptation of the mass exchange system to the reference (optimal) performance indicators, due to the imposition of regulated electric fields of a given intensity on the adsorption processes and recognition of the most effective hydromechanical modes of washing sorbent surfaces with a continuous phase using the turbulization index, i.e., assessing the contribution of the inertial component of the structure filtration flow of a continuous phase through a sorbent layer. A self-adaptive system for automated control of electrical adsorption processes will allow achieving the highest rates of gas emissions purification, with optimal energy consumption for the implementation of mass transfer processes and will provide an opportunity to smooth out technological, large-scale and other factors inherent in specific mass transfer processes and apparatus designs. The most important feature of the developed self-adaptive control system is its multifunctionality and a wide range of variation of operating modes from energy-saving optimal to emergency capture modes in cases of emergency emissions and unforeseen surges in the concentrations of harmful trapped substances from the continuous gas phase flow.
