Claims (13)
1. Een inrichting voor het uitvoeren van een fysisch en/of chemisch proces, in het bijzonder een warmtewisselaar, omvattende een reservoir voorzien van tenminste één stijgpijp waarin een stroom van deeltjes in een fluïdum beweegt tussen een stijgpijpingang en een stijgpijpuitgang om een eerste stroompad te definiëren, waarbij de stijgpijpingang in verbinding staat met een kast, waar tenminste één verdeelplaat is aangebracht voor het ondersteunen van een gefluïdiseerd bed van deeltjes dat in een quasi-stationaire toestand wordt gehouden, waarbij de stijgpijpuitgang via tenminste één scheider is gekoppeld met tenminste één valpijp voor het terugvoeren van deeltjes van de stijgpijpuitgang naar de kast, waarbij in de scheider de stroom van deeltjes in een fluïdum stromend van de stijgpijpuitgang wordt gescheiden in een stroom van deeltjes en een stroom van fluïdum, waarbij in de valpijp, de stroom van deeltjes beweegt tussen een valpijpingang en een valpijpuitgang om een tweede stroompad te definiëren, waarbij de valpijpuitgang is gekoppeld met de kast, met het kenmerk, dat de valpijp een meeneeminrichting omvat om de stroom van deeltjes in het tweede stroompad mee te nemen.
2. Inrichting volgens conclusie 1, waarbij de meeneeminrichting zich althans gedeeltelijk uitstrekt door de valpijp heen met de stroom van deeltjes mee.
3. Inrichting volgens conclusie 1 of 2, waarbij de meeneeminrichting is voorzien van meeneemelementen, bijvoorbeeld, meeneembladen.
4. Inrichting volgens één der voorgaande conclusies, waarbij de meeneeminrichting is ingericht om te bewegen met een instelbare meeneemsnelheid.
5. Inrichting volgens één der voorgaande conclusies, waarbij de meeneeminrichting een roterende meeneeminrichting is, bij voorkeur met een rotatie-as die zich langs de valpijp uitstrekt.
6. Inrichting volgens één der voorgaande conclusies, waarbij de meeneeminrichting is ingericht om de stroom van deeltjes langs een helixachtig pad mee te nemen.
7. Inrichting volgens één der voorgaande conclusies, waarbij de meeneeminrichting een schroefpomp is.
8. Inrichting volgens één der voorgaande conclusies, waarbij de stroom van deeltjes in een fluïdum in de stijgpijp opwaarts beweegt tussen een stijgpijpingang en een stijgpijpuitgang.
9. Inrichting volgens één der voorgaande conclusies, waarbij de stroom van deeltjes in de valpijp neerwaarts beweegt tussen een valpijpingang en een valpijpuitgang.
10. Inrichting volgens één der voorgaande conclusies, waarbij de valpijp buiten het reservoir is op gesteld.
11. Inrichting volgens één der voorgaande conclusies, waarbij in een bovensectie van de valpijp, de stroom van deeltjes een vochtige stroom van deeltjes is en/of in een ondersectie van de valpijp de stroom van deeltjes in hoofdzaak droog is.
12. Gebruik van een roterende positieve verplaatsingsinrichting, bijvoorbeeld een schroefpomp als een meenneeminrichting in een inrichting voor het uitvoeren van een fysisch en/of chemisch proces, in het bijzonder een warmtewisselaar, bijvoorbeeld in een valpijp.
13. Werkwijze voor het bewegen van een stroom van deeltjes van een valpijpingang naar een valpijpuitgang, waarbij de stroom van deeltjes benedenwaarts worden meegenomen door een meeneeminrichting.
