Definitions

  • the invention relates to a cyclone for gas enrichment of gas mixtures of different densities, in particular for increasing the oxygen content of air.
  • This gas enrichment causes a higher concentration of the gas to be enriched after leaving the cyclone, which means that more favorable process data can be obtained in subsequent reactions of this gas.
  • enriching air with oxygen better combustion conditions are achieved with subsequent combustion and at the same time the proportion of pollutants in the exhaust gases is reduced.
  • the gas enrichment is mainly effected today by adsorbing and absorbing unwanted components in special gas cleaning devices (cyclones, centrifuges, venturi washers, etc.).
  • the auxiliary media used to absorb the unwanted components are retained using gravity or other energy fields (electrostatic, etc.). Fixed filters with auxiliary media are periodically replaced.
  • the state of knowledge in the field of gas enrichment which can be viewed as gas cleaning from a different perspective, is described in an article by Prof. Dr. HW Thoenes shown (HWThoenes: Development tendencies in environmental protection technology, in technical communications, 73rd year, February 1980, Issue 2, p. 101). In this article, which also deals with the separation of gaseous pollutants (ibid., P.
  • the invention has for its object, bypassing auxiliary media to enrich the gas mixture directly due to the different acceleration of individual gas components in the cyclone.
  • This object which was previously only achieved for gas / solid mixtures, is also achieved by the invention for gas mixtures, in particular for air (nitrogen / oxygen mixture).
  • the gas enrichment is effected by a cyclone in which the gas mixture flowing due to an existing pressure difference is forced into a spiral movement which accelerates gas particles of different weights to different extents.
  • the thus entering stochastic Areichtation of the heavier component in the internal outer radius of the cyclone and the lighter component in the vicinity of the cyclone axis is for the enrichment of each desired gas remplibe.I
  • the oxygen richer, heavier air (liter weight O 2: 1.42895 g) taken from the outer radius of the cyclone, the lighter, more nitrogen-rich air (liter weight N 2 : 1.25046 g) near the central axis. is suctioned off.

Abstract

Avec ce cyclone on obtient un enrichissement aussi bien des composants lourds (A) que des composants légers (B) d'un mélange de gaz (AB). Cet enrichissement a lieu sans utiliser des médiums auxiliaires, seulement en raison des différentes forces cinétiques qui agissent le long d'un parcours en spirale sur les composants du gaz ayant des poids différents. Le composant léger enrichi (B) est aspiré près de l'axe du cyclone et le composant lourd (A) enrichi quitte le cyclone par une tubulure (6) fixée sur la paroi extérieure. En particulier, en utilisant le cyclone pour enrichir en oxygène l'air de combustion, constitué d'un mélange d'oxygène et d'azote, on améliore le processus de combustion tout en réduisant la teneur en substances nuisibles des gaz d'échappement.
