COMPARATIVE ANALYSIS OF MODELS OF VENTILATION OF THE SUBSTRATE WITH THE COMPOSTING

abstract 1231609086 issue 123 pp. 1268 – 1278 30.11.2016 ru 407
In the article we consider the questions of modeling of temperature changes in the composting process, the changes of oxygen concentration and temperature with the air from the environment, produced the effect of composting heat exchange mass with the environment, the selected state variables and the control bioreactor, the dependence of the coefficients of the system equations of motion from the variable state of the object.

COMPARATIVE ANALYSIS OF THE VENTILATION MODELS OF THE SUBSTRATE WHEN COMPOSTING

abstract 1221608071 issue 122 pp. 1033 – 1045 31.10.2016 ru 346
In the article we have performed a comparative analysis of a traditional system of air supply to the bioreactor during the composting process and the developed system with lateral air supply. We have proven to reduce temperature variation of the substrate as a result of the use of the ventilation system by 35%. During the simulation, equal to 1.0 hour, a ventilation system with side air flow provides a reduction of the accumulated degree of heterogeneity of status parameters of the substrate by 58%. Use of the ventilation system with side air flow reduces the duration of technological cycle of composting 7 %.

FORMULATION AND SOLUTION OF THE PROBLEM OF DISCRETE CONTROL IN THE THERMOPHILIC STAGE OF THE COMPOSTING PROCESS

abstract 1301706063 issue 130 pp. 883 – 893 30.06.2017 ru 436
The article formulates and solves the task of discrete control in the thermophilic stage of the composting process. It is shown, that considering the relay control entity to maintain specified process conditions requires the organization of the sliding mode. We have solved the problem of minimizing the temperature deviation of the substrate from the set values and the deviation of the oxygen concentration in the gas phase of the bioreactor from the specified values. The article shows an algorithm to compute the discrete control of the composting process in the thermophilic stage.

MATHEMATICAL MODEL OF A VENTILATION SYSTEM WITH VARIABLE AIR FLOW ALONG THE VERTICAL AXIS OF THE REACTOR IN THE COMPOSTING PROCESS

abstract 1211607119 issue 121 pp. 1887 – 1896 30.09.2016 ru 575
In the article, we present the mathematical model of a ventilation system with variable air flow along the vertical axis of the reactor in the composting process. We have solved the problem of the choice of the method of supplying air to the bioreactor, reducing the temperature of the substrate along the axis of the bioreactor. The proposed method provides a reduction of temperature and moisture content of the gas phase, which leads to a change in the dynamics of the composting process.
