The determination of hydraulic resistance during laminar filtration through layers of sorbents and ion-exchange granules in environmental mass exchange equipment

This paper provides a program and algorithm for automated calibration of technological parameters of an electroadsorption apparatus with a fixed adsorbent layer. The basic physical principles that allow obtaining the necessary information about the ranges of regulation of the electric field parameters and the development of dynamics of filtration modes of the continuous gas phase flow through the adsorbent layer are described. The technological parameters obtained during calibration and their control ranges serve as the basis for implementing a program for controlling the operating modes of electroadsorption apparatuses during the current operation of technological equipment.

This paper provides new designs of electroadsorption apparatuses of continuous and semi-periodic action, with fixed, moving and fluidized layers of adsorbents. There were considered the designs of apparatuses, action principle and the main intensifying effects aimed at improving the efficiency of gas emission treatment, efficiency improving of sorption apparatuses, improving the capacity of adsorbents and extending the time of their protective action, this together forms a new direction for the development and designing of energy- and resource-saving designs of electroadsorption apparatuses for selective purification of gas emission treatment and liquid discharges for various industries, able to respond adaptively to sharp spikes in concentrations of harmful substances in streams of continuous gas (liquid) phases and adjust to emergency capture modes.

This paper provides a new scheme and algorithm of automated control of modes of operation of electroadsorption mass transfer apparatuses are presented on the example of a continuously operating electroadsorber with a fixed adsorbent layer. The required values of technological parameters and ranges of their regulation were obtained during the calibration of technological parameters at the stage of commissioning of the electric adsorption mass transfer equipment, also in an automated mode. A detailed description and algorithm of the stages of calibration of technological parameters of electroadsorption apparatuses with a fixed adsorbent layer are given in the second part of this work (Calibration of technological parameters of an electroadsorption apparatus with a fixed layer of adsorbent). The principle of automated control consists in self-adaptation of the mass exchange system to optimal productiveness, due to the imposition of adjustable electric fields of a given intensity on the adsorption processes and recognition of the most effective hydromechanical modes flow about of the surfaces of the adsorbent granules with a continuous gas phase flow using the turbulization index, that is, assessing the contribution of the inertial component of the structure filtration flow of a continuous gas phase flow through the adsorbent layer. A self-adaptive automated control system for electroadsorption processes will allow achieving the highest levels of gas emissions purification, with optimal energy costs for 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 multi-functionality and a wide range of variation of operating modes from energy-saving optimal modes to emergency capture modes in cases of emergency emissions and unexpected bursts of concentrations of harmful captured substances from the continuous gas phase flow.
