Abstract
The present disclosure describes a method for discharging a hydrogen storage system, which is found in the annular space of a receiver tube, in particular for solar collectors, wherein the annular space is formed between an outer-lying tubular jacket and an inner-lying absorber tube of the receiver tube, and the outer-lying tubular jacket is connected via a wall to the absorber tube in a gas-tight manner. The method is hereby characterized in that an opening penetrating the tubular jacket or the wall is produced, free hydrogen in the annular space is pumped out through the opening, and the opening is subsequently sealed. The disclosure further describes a device for implementing the method.
Claims22
A method for discharging a hydrogen storage system, wherein the hydrogen storage system is in the annular space of a receiver tube, wherein the annular space is defined at least by an outer-lying tubular jacket and an inner-lying absorber tube of the receiver tube, and wherein the outer-lying tubular jacket is connected by a wall to the absorber tube, the method comprising the steps of:
- producing an opening penetrating through the tubular jacket or the wall;
- pumping free hydrogen in the annular space out through the opening;
- and
- subsequently sealing the opening.
A device for discharging a hydrogen storage system, wherein the hydrogen storage system is in the annular space of a receiver tube, wherein the annular space is defined at least by an outer-lying tubular jacket and an inner-lying absorber tube of the receiver tube, and wherein the outer-lying tubular jacket is connected with a wall to the absorber tube, the device comprising:
- a process chamber;
- a laser driller for producing an opening through the tubular jacket or the wall;
- a pump for pumping out hydrogen from the annular space;
- and
- a sealer for sealing the opening.
