Claims (14)

1. Belufter til beluftning af vand, omfattende et distributionssystem (4) til fordeling af luft under vandoverfladen og en kompressor (2) med et luftindtag og mindst et luftudtag (23), hvorved kompressoren (2) bliver indrettet til at blive anbragt under vandoverfladen af denne kompressor (2), der er forsynet med et kabinet, der forhindrer indtrængning af vand ind i kompressoren (2), hvorved indtrængning af vand ved luftindtaget forhindres af en indsugningsmanifold (3), der er tilvejebragt således at en åben ende er over vandoverfladen, og den anden åbne ende har en vandtæt forbindelse til kompressoren (2), hvorved indtrængning af vand ved luftudtaget (23) bliver forhindret, fordi distributionssystemet (4) har en vandtæt forbindelse til luftudtaget (23) og på grund af sin art, eller med mindst én ventil kan holde vandet tilbage, og hvorved kabinettet er i termisk kontakt med vandet for at afkøle kompressoren (2), kendetegnet ved at kompressoren (2) er en centrifugal kompressor, der indeholder et vingehjul (21), der drives af en aksel (17), der er monteret på luftlejer (24), magnetiske lejer eller begge.
2. Belufter ifølge krav 1, kendetegnet ved at distributionssystem (4) omfatter mindst en diffusor (12).
3. Belufter ifølge krav 1 eller 2, kendetegnet ved at distributionssystem (4) omfatter mindst to distributionsarme (11), der fører væk fra kompressoren (2), hver udstyret med mindst to diffusorer (12).
4. Belufter ifølge krav 2 eller 3, kendetegnet ved at en distributionsarm (11) er forsynet med en sidelæns gren (28), der er udstyret med mindst en diffusor (12).
5. Belufter ifølge krav 1, kendetegnet ved at akslen (17) er forsynet med et hulrum, der strækker sig i længden af akslen (17), og at kompressoren (2) er forsynet med en luftkanal, der løber fra tryksiden til indtagelsen via hulrummet.
6. Belufter ifølge ethvert af de foregående krav, kendetegnet ved at kompressoren (2) og distributionssystem (4) er anbragt, så de kan rotere omkring en lodret akse (A-A').
7. Belufter ifølge krav 6, kendetegnet ved at distributionssystemet (4) er udstyret med en dyse (29) med en retning, der har mindst en komponent vinkelret på den radiale retning.
8. Belufter ifølge krav 6 eller 7, kendetegnet ved at belufteren hviler på en drejeskive (14), der er beregnet til at hvile på bunden af et reservoir, hvori vandet er placeret.
9. Belufter ifølge ethvert af de foregående krav, kendetegnet ved at luftindgang og/eller udgang (23) på kompressoren (24) er placeret under motoren og vingehjulet (21).
10. Belufter ifølge ethvert af de foregående krav, kendetegnet ved at belufteren kan (1) tages ud af vandet som helhed ved hjælp af et håndtag (7), der er fastgjort på toppen af belufteren (1).
11. Belufter ifølge krav 10, kendetegnet ved at distributionssystemet (4) er forbundet med kompressoren (2) på en måde, der er selvbærende, eller støttemidler (13) bliver tilvejebragt på belufteren (1) for at understøtte distributionssystemet (4).
12. Belufter ifølge krav 9, kendetegnet ved at forbindelserne mellem kompressoren (2) og indsugningsmanifolden (3) og mellem luftudtaget (23) og distributionssystemet (4) er aftagelige, hvorved en ventil i hvert af indtagets rør (3) og distributionssystemet (4) forhindrer indtrængning afvand.
13. Vandrensningsanlæg, der omfatter mindst et vandbassin, der skal beluftes, kendetegnet ved at en komponent af vandrensningsanlægget er en belufter (1) ifølge ethvert af de foregående krav.
14. Anvendelse af en belufter ifølge ethvert af kravene 1-12 til indføring af luft i spildevandet, der skal renses.
