Claims (10)

1. Kontinuert fremgangsmåde til tørring af slam, omfattende en blanding (A) af fugtig slam med et opdelt fast materiale i en strømning af gas, en opvarmning (6) af blandingen, som er tilstrækkelig til at tilvejebringe tørringen af slammet ved fordampning af dets fugtighed i gassen, efterfølgende en adskillelse (8) af slam, som er tørret, fra gassen, som er blevet fugtig, og det opdelte faste materiale, ved hvilken gassen, som er blevet fugtig, komprimeres (10) under tilvejebringelse af en temperaturforøgelse, efterfølgende anvendes til at effektuere opvarmningen af en efterfølgende portion af blandingen ved kondensering af fugtigheden i den nævnte fugtige gas; og blandingen drives i pulveriseret form ved strømningen af gassen under tørringen idet den følger en opdelt strømning i adskillige blæseledninger (25) for den nævnte blanding og den ledning, som følges af den gas, som er blevet fugtig, danner en kappe (26), som omgiver de adskillige blæseledninger (25).
2. Fremgangsmåde til tørring af slam ifølge krav 1, kendetegnet ved, at gassen, efter at have effektueret opvarmningen, tørres (11) og recirkuleres (H) til en anden efterfølgende portion af blandingen.
3. Fremgangsmåde til tørring af slam ifølge krav 2, kendetegnet ved, at den tørrede gas genopvarmes (12) før den returneres til den anden efterfølgende portion af blandingen.
4. Fremgangsmåde til tørring af slam ifølge ethvert af kravene 2 eller 3, kendetegnet ved, at den tørrede gas anvendes til at drive blandingen igennem en location (6) for tørring af slam og frem til en location (8) for adskillelse.
5. Anlæg til tørring af slam, omfattende en blander (1) for fugtigt slam og et opdelt fast materiale, en injektor (4, 36) for en strømning af gas placeret ved en udgang fra blanderen (1), en tørrer (6, 38) for slam, en separator (8) for slam, som er tørret, opdelt fast materiale og gas som er blevet fugtig, en indretning for transport (5, 25, 37, 39) af blandingen imellem blanderen (1) og separatoren (8), igennem tørreren, en ledning (9), som forbinder separatoren (8) med tørreren (6, 38) og som følges af den gas, som er blevet fugtig, en kompressor (10), som foreligger imellem separatoren og tørreren, idet tørreren er en varmeveksler imellem den gas, som er blevet fugtig, og blandingen, injektoren (4, 36) er en injektor, som i pulveriseret form driver slammet og det opdelte faste materiale, og organerne til transport af blandingen består, efter injektoren (4), af adskillige blæseledninger (25) for blandingen, som passerer igennem tørreren (6, 38), idet den ledning, som følges af den gas, som er blevet fugtig, danner en kappe (26), som omgiver de adskillige blæseledninger (25).
6. Installation til tørring af slam ifølge krav 5, kendetegnet ved, at kappen (26) har en bund, som er forsynet med et udløb for vand (28, 29).
7. Installation til tørring af slam ifølge krav 5 eller 6, kendetegnet ved, at ledningen (9) også forbinder tørreren (6, 38) med injektoren (4, 36), idet den forløber igennem en befugtningsindretning (11) for gas.
8. Anlæg til tørring af slam ifølge ethvert af kravene 5 til 7, kendetegnet ved, at organerne for transport af blandingen omfatter en tromle (39), som roterer i tørreren (38), og at den ledning, som følges af den gas, som er blevet fugtig, danner en kappe, som omgiver tromlen.
9. Anlæg til tørring af slam ifølge krav 6, kendetegnet ved, at kappen er opdelt af chikaner (27) i horisontalt rettede kamre, idet hvert af kamrene er forsynede med et afløb for vand (28), som udmunder under kamrene og strækker sig under kamrene.
10. Anlæg til tørring af slam ifølge ethvert af kravene 5 til 9, kendetegnet ved, at det omfatter en overheder (7) for blandingen imellem tørreren og separatoren, eller en forvarmer (12) for gassen imellem indretningen til befugtning af gassen og injektoren, eller begge dele, som eneste kilder for ekstern varme.
