DETERMINATION OF CONCENTRATION PROFILE effluent and lifetime CARTRIDGES air-purifying respirator

摘要

FIELD: chemistry.;SUBSTANCE: method of determining, at least, one of a profile of the output flow concentration, the time of breakthrough and a recommendation with respect to a filtering cartridge, consists in the fact that, at least, one input parameter is accepted; at least, one of the profile of the output flow concentration, the time of breakthrough and the recommendation with respect to the filtering cartridge is determined on the basis of the input parameter; and, at least, one of the profile of the output flow concentration, the time of breakthrough and the recommendation with respect to the filtering cartridge is graphically represented. The profile of the output flow concentration contains a graph of the concentration of chemical substances for the period of time, the time of breakthrough contains the time, during which a predetermined concentration of the chemical substances passes through the filtering cartridge. The invention also relates to a machine-readable data carrier, containing commands for the implementation of the method and systems for the determination of, at least, one of the profile of the output flow concentration, the time of breakthrough and the recommendation with respect to the filtering cartridge. The system contains the user's interface for entering input parameters, a processing unit, determining, at least, one of the profile of the output flow concentration, the time of breakthrough and the recommendation with respect to the filtering cartridge on the basis of the input parameter; and an output device, connected to the processing unit, which represents, at least, one of the profile of the output flow concentration, the time of breakthrough and the recommendation with respect to the filtering cartridge. The profile of the output flow concentration contains the graph of the concentration of the chemical substances for the period of time, the time of breakthrough contains the time, during which the predetermined concentration of the chemical substances passes through the filtering cartridge.;EFFECT: method improvement.;13 cl, 6 dwg
