Abstract

The invention relates to an apparatus for introduction of droplets into a reactor, comprising a holder for at least one dropletizer unit, where the dropletizer unit has a feed for a liquid to be dropletized and a dropletizer plate and the dropletizer plate has holes through which a liquid to be dropletized is introduced into the reactor, where the holder for the at least one dropletizer unit can be pushed into the reactor or pulled out of the reactor through an opening in the shell of the reactor. At least one rail is accommodated within the reactor and is used to guide the holder for the at least one dropletizer unit along it.

First claim

The invention claimed is:

1. A reactor with an apparatus for introduction of droplets into a reactor ( 1 ), comprising a holder ( 31 ) for at least one dropletizer unit ( 61 ), where the dropletizer unit ( 61 ) has a feed ( 65 ) for a liquid to be dropletized and a dropletizer plate ( 67 ) and the dropletizer plate ( 67 ) has holes ( 69 ) through which a liquid to be dropletized is introduced into the reactor ( 1 ), where the holder ( 31 ) for the at least one dropletizer unit ( 61 ) can be pushed into the reactor ( 1 ) or pulled out of the reactor ( 1 ) through an opening ( 37 ) in the shell of the reactor ( 1 ), wherein at least one rail ( 45 ) is accommodated within the reactor ( 1 ) and is used to guide the holder ( 31 ) for the at least one dropletizer unit ( 61 ) along it.

2. The reactor according to claim 1 , wherein the holder ( 31 ) for the at least one dropletizer unit ( 61 ) being guided is suspended on the rail.

3. The reactor according to claim 1 , wherein the holder ( 31 ) being guided within the reactor rests on two rails ( 45 ).

4. The reactor according to claim 3 , wherein the rails are two contact surfaces ( 45 ) on a pipe ( 41 ) which is open at the bottom and on which the holder ( 31 ) for the at least one dropletizer unit ( 61 ) rests.

5. The reactor according to claim 4 , wherein the contact surfaces ( 45 ) run parallel to the opening ( 43 ) at the base of the pipe ( 41 ).

6. The reactor according to claim 4 , wherein the contact surfaces ( 45 ) bound the opening ( 43 ) at the base of the pipe ( 41 ) in axial direction.

7. The reactor according to claim 1 , wherein at least one rail ( 35 ) is provided in the region of the opening ( 37 ) outside the reactor ( 1 ) and is used to guide the holder ( 31 ) for the at least one dropletizer unit ( 61 ) along it when it is pulled out of the reactor ( 1 ) or pushed into the reactor ( 1 ).

8. The reactor according to claim 7 , wherein the at least one dropletizer unit ( 61 ) can be deinstalled outside the reactor ( 1 ).

9. The reactor according to claim 1 , wherein a flap ( 39 ) mounted in the opening ( 37 ) can be used to close the opening ( 37 ) when the holder ( 31 ) for the at least one dropletizer unit ( 61 ) has been pulled out.

10. The reactor according to claim 9 , wherein the flap ( 39 ) is mounted on the outside of the reactor shell and is closed electrically, mechanically, hydraulically or pneumatically when the holder ( 31 ) for the at least one dropletizer unit ( 61 ) has been pulled out of the reactor ( 1 ).

11. The reactor according to claim 1 , wherein a stop ( 51 ) formed at the end of the holder ( 31 ) for the at least one dropletizer unit ( 61 ) stops the holder ( 31 ) for the at least one dropletizer unit ( 61 ) at the inside of the reactor shell when it is pulled out, and closes the opening ( 37 ) when the holder ( 31 ) for the at least one dropletizer unit ( 61 ) has been pulled out.

12. The reactor according to claim 1 , wherein the holder ( 31 ) is a frame having a space ( 33 ) for the dropletizer unit ( 61 ).

13. The reactor according to claim 12 , wherein the frame has spaces ( 33 ) for several dropletizer units ( 61 ).

14. The reactor according to claim 1 , wherein each dropletizer unit ( 61 ) has a housing ( 63 ) concluded by the dropletizer plate ( 67 ) at the base thereof.

15. The reactor according to claim 14 , wherein the feed ( 65 ) for the liquid to be dropletized comprises a flexible pipeline or hose, the flexible pipeline or hose opening into the housing ( 63 ) above the dropletizer plate ( 67 ).

16. The reactor according to claim 1 , wherein the holder ( 31 ) for the at least one dropletizer plate ( 61 ) is guided on the at least one rail ( 45 ) with rollers or slide contacts ( 47 ).

17. The reactor according to claim 16 , wherein the material used for the slide contacts ( 47 ) is a polymer based on polyether ether ketone, polyoxymethylene, polyamide, polyethylene terephthalate or polytetrafluoroethylene.
