At present, instead of a direct combustion of solid fuel, its thermochemical conversion is ex-tensively used to produce a generator gas. The use of this technology is connected with the need for gas purification. One of the promising and widely spread sorbents for the purification of the generator gas is dolomite, whose particles compose the active component of the bed filters. Forecasting the technological characteristics of the functioning of the bed filters of a various design is an extremely urgent task. The objective of the study is to develop a method for forecasting and calculating the oper-ation of sorption systems for purification of the generator gas based on dolomite. It is achieved by constructing and verifying a mathematical model of the functioning of the bed sorption filter with a radial-axial flow pattern of the generator gas through the dolomite filling. The Markov chains theory of a mathematical apparatus is used to design the one-dimensional mathematical model of the process with discrete space and time. The main recurrent balance ratio is formed at each calculation step taking into account the current characteristics of the process, which makes the model nonlinear. The signifi-cance of the research is that an approach to the problem of increasing the reliability of the description and reliability of forecasting technological processes in a bed filter was proposed based on the construction of mathematical models of these processes, in which the filter is considered as a system with distributed characteristics, and the calculation was based on local exchange potentials between particles and gas. |
