Claims (4)
1. Injektionsdyse (1) til urinstofopløsning, hvor en strømningsbane (2c, 3c) for urinstofopløsning, som tilleder urinstofopløsningen, og en gasstrømningsbane (2d, 4d), som tilleder gassen, er konfigureret, og hvor en urinstofopløsning og gas blandes og derefter bliver injiceret fra en injektionsport (4e), hvor injektionsdysen (1) til urinstofopløsning indbefatter en forgreningsstrømningsbane (4f), der står i forbindelse med gasstrømningsbanen (2d, 4d), og en blandingsstrømningsbane (4c), der står i forbindelse med gasstrømningsbanen (2d, 4d) og strømningsbanen (2c, 3c) for urinstofopløsning, og gassen tilledt fra gasstrømningsbanen (2d, 4d) blandes med urinstofopløsningen tilledt fra strømningsbanen (2c, 3c) for urinstofopløsning i blandingsstrømningsbanen (4c), kendetegnet ved, at gassen tilledt fra gasstrømningsbanen (2d, 4d) kommer via forgreningsstrømningsbanen (4f) til en sideoverflade-udtømningsport tilvejebragt opstrøms for injektionsporten (4e) i sideoverfladen af injektionsdysen (1) til urinstofopløsning og udtømmes fra sideoverflade-udtømningsporten langs den yderste udækkede overflade (4b) af injektionsdysen (1) til urinstofopløsning i samme retning som en injektionsretning af urinstofopløsningen.
2. Injektionsdyse (1) til urinstofopløsning ifølge krav 1, hvor injektionsdysen (1) til urinstofopløsning indbefatter et dobbeltrør (2), en luftdyse (4) og en møtrik (5), dobbeltrøret (2) indbefatter strømningsbanen (2c, 3c) for urinstofopløsning, gasstrømningsbanen (2d, 4d) og forgreningsstrømningsbanen (4f), luftdysen (4) er koblet til dobbeltrøret (2) med møtrikken (5), og sideoverflade-udtømningsporten er konfigureret mellem møtrikken (5) og luftdysen (4) og er konfigureret på den ydre omkreds af luftdysen (4), således at den omgiver injektionsdysen (1) til urinstofopløsning.
3. Injektionsdyse (1) til urinstofopløsning ifølge krav 2, hvor sideoverflade-udtømningsporten er en spalte (5d).
4. Injektionsdyse (1) til urinstofopløsning ifølge krav 3, hvor et rum (5c), hvori gassen indeholdes, er konfigureret til at omgive injektionsdysen (1) til urinstofopløsning, og forgreningsstrømningsbanen (4f) og sideoverflade-udtømningsporten er i forbindelse med rummet (5c).
