Abstract

In this work, a series of parametric calculations was made for the processes of sorption and desorption of water vapor in relation to the conditions of the process of sorption air purification. A mathematical model was developed that adequately reflects the processes of heat and mass transfer in the adsorption unit at all stages of the adsorption cycle. Algorithms for solving problems and programs for calculating heat and mass transfer processes in an adsorption regenerated installation are obtained, results of parametric calculations of heat and mass transfer processes at each stage of the adsorption cycle and for the entire cycle as a whole are obtained.

Highlights

  • The main objective of research to improve adsorption air purification systems is to reduce energy costs

  • Due to the large number of parameters that determine the efficiency of the drying process, a complete cycle analysis is largely determined by the availability and implementation of reliable mathematical models and calculation algorithms in engineering practice

  • It is possible both to take into account the features of the flow of heat and mass transfer processes at each of the steps of the cycle, and their interaction during the transition from the previous step to the [7-14]

Summary

Introduction

The main objective of research to improve adsorption air purification systems is to reduce energy costs. One of the requirements for the predrying unit is to ensure, as possible, a lower dew point temperature of the air at the outlet from the unit (not higher than minus 40 C) over the entire range of operating parameters of the system. Due to the large number of parameters that determine the efficiency of the drying process, a complete cycle analysis is largely determined by the availability and implementation of reliable mathematical models and calculation algorithms in engineering practice On their basis, it is possible both to take into account the features of the flow of heat and mass transfer processes at each of the steps of the cycle, and their interaction during the transition from the previous step to the [7-14].
