Abstract

A device for generating a decontaminating agent vapor, in particular hydrogen peroxide vapor, comprising a single- or multipart evaporator body ( 1 ); a heating device for heating the evaporator body ( 1 ); at least one supply channel, preferably multiple supply channels, for supplying a liquid decontaminating agent to be evaporated, in particular hydrogen peroxide, to at least one of multiple blind holes ( 7, 8, 9, 10 ) arranged in the evaporator body ( 1 ); and a flow channel ( 2 ) which is arranged above the upper blind holes edges ( 11, 12, 13, 14 ) of the blind holes ( 7, 8, 9, 10 ) and which connects a carrier medium inlet ( 3 ) to an outlet ( 4 ) in a gas-conductive manner for a gaseous carrier medium, in particular air, in order to discharge the decontaminating agent vapor through the outlet ( 4 ) in a flow direction of the carrier medium. According to the invention, at least two of the blind holes ( 7, 8, 9, 10 ), preferably all of the blind holes ( 7, 8, 9, 10 ), are fluidically connected together at a distance from the respective upper blind hole edges ( 11, 12, 13, 14 ).

Claims (24)

1. A device for generating decontaminating agent vapor, comprising a single- or multi-part evaporator body ( 1 ), a heating device for heating the evaporator body ( 1 ) as well as at least one supply channel for supplying a liquid decontaminating agent to be evaporated, to at least one of multiple blind holes ( 7 , 8 , 9 , 10 ) arranged in the evaporator body ( 1 ), and to a flow channel ( 2 ) for a gaseous carrier medium arranged above upper blind hole edges ( 11 , 12 , 13 , 14 ) of the multiple blind holes ( 7 , 8 , 9 , 10 ) and connecting a carrier medium inlet ( 3 ) to an outlet ( 4 ) in a gas-conducting manner for discharging the decontaminating agent vapor through the outlet ( 4 ) in a flow direction of the gaseous carrier medium, wherein the flow channel is defined by a side wall, and the upper blind hole edges are defined in the side wall,

wherein

at least two of the multiple blind holes ( 7 , 8 , 9 , 10 ) are connected to one another in a fluidic manner at a distance to their respective upper blind hole edges ( 11 , 12 , 13 , 14 ) by fluidic connection ( 19 , 20 , 21 , 22 ), and wherein a base of the fluidic connection ( 19 , 20 , 21 , 22 ) is configured as an evaporator surface heatable by the heating device, so that decontaminating agent vapor generated thereon can ascend into the flow channel ( 2 ) via the at least two of the multiple blind holes ( 7 , 8 , 9 , 10 ) connected to one another by means of the fluidic connection ( 19 , 20 , 21 , 22 ), and

wherein the fluidic connection ( 19 , 20 , 21 , 22 ) is configured such that the fluidic connection ( 191 , 20 , 21 , 22 ) connects a deepest region ( 27 , 28 , 29 , 30 ) of each of the at least two of the multiple blind holes ( 7 , 8 , 9 , 10 ), which are connected to one another in fluidic manner, in a common plane, and wherein the fluidic connection ( 19 , 20 , 21 , 22 ) is at least partially defined by a surface in the common plane at the deepest region ( 27 , 28 , 29 , 30 ).

2. The device according to claim 1 , wherein the fluidic connection ( 19 , 20 , 21 , 22 ) comprises a circumferentially closed connection channel in the single- or multi-part evaporator body ( 1 ).

3. The device according to claim 2 , wherein the circumferentially closed connection channel is between two blind holes ( 7 , 8 , 9 , 10 ) fluidically connected to one another.

4. The device according to claim 1 , wherein the fluidic connection ( 19 , 20 , 21 , 22 ) is produced by milling high-grade steel in radial direction with respect to longitudinal center axes of the multiple blind holes ( 7 , 8 , 9 , 10 ).

5. The device according to claim 1 , wherein the upper blind hole edges ( 11 , 12 , 13 , 14 ) of the multiple blind holes ( 7 , 8 , 9 , 10 ) fluidically connected to one another are arranged in a common plane.

6. The device according to claim 5 , wherein the upper blind hole edges ( 11 , 12 , 13 , 14 ) of all blind holes ( 7 , 8 , 9 , 10 ) fluidically-connected to one another are arranged in the common plane.

7. The device according to claim 1 , wherein the upper blind hole edges ( 11 , 12 , 13 , 14 ) are defined in and located on a bent, cylindrical shell surface section of the side wall defining the flow channel ( 2 ).

8. The device according to claim 7 , wherein the upper blind hole edges extend laterally up along a curved inner surface of the bent, cylindrical shell surface section, away from bottom dead center of the flow channel ( 2 ), and the upper blind hole edges of the multiple blind holes are defined on either side of, and spaced from, a section of the side wall extending along bottom dead center of the flow channel.

9. The device according to claim 1 , wherein at least two of the multiple blind holes ( 7 , 8 , 9 , 10 ) fluidically connected to one another are arranged to be spaced apart in the direction of the flow direction of the gaseous carrier medium and/or wherein at least two of the multiple blind holes ( 7 , 8 , 9 , 10 ) fluidically connected to one another are arranged to be spaced apart perpendicular to the flow direction of the gaseous carrier medium.

10. The device according to claim 1 , wherein the heating device is arranged in the single- or multi-part evaporator body ( 1 ) directly below each blind hole bottom in a virtual extension of a respective blind hole longitudinal center axis.

11. The device according to claim 1 , wherein the decontaminating agent vapor is hydrogen peroxide vapor and the gaseous carrier medium is air.

12. The device according to claim 1 , wherein the at least one supply channel comprises multiple supply channels.

13. The device according to claim 1 , wherein all multiple blind holes ( 7 , 8 , 9 , 10 ) are connected to one another in a fluidic manner at a distance to their respective upper blind hole edges ( 11 , 12 , 13 , 14 ).

14. The device according to claim 1 , wherein the fluidic connection has a planar base surface.

15. Arrangement, comprising a space to be decontaminated and a device according to claim 1 by means of which the space can be applied with decontaminating agent vapor.

16. The arrangement according to claim 15 , wherein the space is an isolator and/or a lock.

17. A method for operating a device for generating decontaminating agent vapor, according to claim 1 , wherein liquid decontamination agent is supplied dropwise via the at least one supply channel into at least one of the blind holes ( 7 , 8 , 9 , 10 ),

wherein

liquid decontamination agent supplied into one of the multiple blind holes ( 7 , 8 , 9 , 10 ) flows into at least another one of the multiple blind holes ( 7 , 8 , 9 , 10 ) and is evaporated into liquid decontamination agent vapor there.

18. The method according to claim 17 , wherein part of the liquid decontamination agent flowing through the fluidic connection ( 19 , 20 , 21 , 22 ) evaporates in the fluidic connection ( 19 , 20 , 21 , 22 ) and/or wherein part of the liquid decontamination agent flowing through the fluidic connection ( 19 , 20 , 21 , 22 ) flows to yet a further blind hole ( 7 , 8 , 9 , 10 ) via the other blind hole ( 7 , 8 , 9 , 10 ) and a further fluidic connection ( 19 , 20 , 21 , 22 ).

19. The method according to claim 17 , wherein the total volume flow of the liquid decontamination agent supplied to the evaporator body ( 1 ) is kept constant.
