Automatic Control of Operating Modes of Packed Apparatus for Selective Gas Emissions Cleaning

Abstract

A modified system for automatic control of hydrodynamic operating modes of packed adsorption columns for the selective cleaning of gas emissions is described, which allows automatic adjustment of the operating modes of packed mass transfer apparatus. Presents the scheme and algorithm of developed system with the automatic adjustment (calibration) mode of main operating parameters. The main features and advantages of using elastically deformable blocks of packed material are given on the example of metal chips, i.e. waste of machine tools as a packed material that meet all requirements of the ongoing mass transfer processes and are amenable to automated regulation. The developed system of automatic regulation of parameters of packed units, but also to solve a very serious environmental problem of industrial waste recovery. A classification technique of studying the hydrodynamics of packed materials, capable of concluding the suitability of this sample of packing material for a specific mass transfer process, in particular the adsorption process for the selective cleaning of gas emissions.

Modelling and calculation of a small-size evaporation cooling apparatus for industrial recirculated water with a heat-and-mass exchange packing based on wastes from metal-working machinery

“…Apart from that, we would like to underscore the fact that many samples of the packing materials represented by the wastes from metal-working machines have significant elastic properties [54,55] (they preserve their elastic properties within a wide range of volumetric deformations of the packing blocks) that enables current automated adjustment of various mass exchange apparatuses operation modes [54][55][56][61][62][63], including evaporation cooling apparatuses for industrial recirculated water [64], thus, self-adaptation of the packing blocks in evaporation cooling apparatuses and shift to energy saving operation modes are available.…”
