Calibration Program

The procedure for automatic calibration of process parameters of electric adsorption mass transfer devices for selective purification of gas emissions is presented on the example of a continuous electric adsorber with a moving adsorbent bed. The calibration program is based on automatic recognition of the ranges of regulation of the operating modes of electric sorption devices at the stage of commissioning or during the current operation of technological mass transfer equipment. The hydrodynamics of the filtration flow through the adsorbent bed and the parameters of the electric field are subject to calibration, while the optimal filtration regimes from the point of view of washing the adsorbent granules with a continuous gas phase flow are recognized. Determination of the control limits for the parameters of the electric field is based on an automatic check of the quality of electrical insulation part of the mass transfer device, as well as recognition of the current arising in the circuit when ions move between charged surfaces (ionic wind). The calibration program and the parameters obtained with its help will enable the self-adaptive system of automated control of electrical adsorption processes to achieve the highest rates of purification of gas emissions, with optimal energy costs 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 device designs.

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.

The article is devoted to the study of the forms of moisture bond in mature cheeses. The kinetics of mass transfer processes depend on the mobility and binding energy of water with solid and dissolved substances. Therefore, the removal of bound water is accompanied by deterioration in kinetics and increased energy consumption. In this regard, information on the state of bound water in substances during dehydration is very important from a scientific point of view and from a practical one. Based on the studies carried out, the forms of moisture bond in various types of cheese were determined by strain-gauge and thermographic methods. Based on this, it has been established that the forms of moisture bond in cheeses can be determined by strain-gauge and thermographic methods.

The work is devoted to the study of forms of moisture connection in Mature cheeses. The kinetics of mass transfer processes depends on the mobility and binding energy of water with the solid phase and solutes. Therefore, the removal of bound water is accompanied by both a deterioration in the kinetics and an increase in energy consumption. In this regard, information about the state of bound water in materials during dewatering is very important not only from a scientific but also from a practical point of view. Based on the conducted research, the forms of moisture binding in various types of cheese were determined by the strain-measuring and thermographic method. On the basis of which it is established that the forms of moisture binding in cheeses can be determined by strain and thermographic methods.
