A new methodology has been developed for determining the volumetric coefficients of internal mass transfer according to the results of an experimental study. The values of volumetric coefficients of internal mass transfer were calculated and their dependence on the technical characteristics of the regeneration process of the sodium-cation exchange filter under dynamic conditions was established. A computer model of the process of regeneration of the sodium-cation exchange filter in nonequilibrium and non-stationary conditions in the form of a computer software package (“Regeneration-1”, “Regeneration-2”), recommended for scientific, design, commissioning and operating organizations, relevant industries. For the first time, the task of optimizing the ion-exchange nonequilibrium regeneration of the sodium-cation exchange filter as a separate stage of the filter cycle was posed and solved. The analytical dependence of optimizing the specific consumption of NaCl salt for nonequilibrium regeneration of the sodium-cation exchange filter as a separate stage of the filter cycle is obtained.
KEY WORDS: integrated power supply of separate facilities, renewable energy sources, alternative energy
ABSTRACT:The relevancy of the study is due to low efficiency of using solar and geothermal energy in the existing process schemes. In this regard, this article is aimed at revealing the possibilities of using solar and geothermal energy for the integrated energy supply of separate facilities from renewable energy sources. The mathematical simulation method based on the theory of graphs of energy system operation, which makes it possible to analyze the efficiency of the integrated use of solar and geothermal energies for the heat-cold supply of separate facilities, is the main approach to studying this problem. Energy consumption throughout the year and the emergency energy source capacity in "peak" modes were determined based on the developed mathematical model of managing the system of integrated power supply of separate facilities from renewable energy sources plotted with the use of the theory of graphs. The article materials are of practical value for the designers of the systems of integrated heat-cold supply of separate facilities.
The research relevance is conditioned by decrease in installations efficiency and high fuel consumption due to scale formation on heat-exchange surfaces, and conditioned by transition to ecologically clean, resource-saving power engineering and increase in hydrocarbon raw materials extraction efficiency. In this connection, this article aims at contact type heat generators application disclosing possibilities. The main approach to the study of this problem is the heat-transfer agent contact heating application. This article materials practical value is for complex heat supply systems engineers and designers.
