Abstract
A transfer device includes at least one pump unit provided for a defined gas transfer between a first, closed-off space of an installation, in particular a photobioreactor installation, and a second space which is separate from the first space. The at least one pump unit is embodied as a selective oxygen pump.
Claims18
An installation comprising
- a first, closed-off space;
- a transfer device with at least one pump unit for a defined gas transfer between the first space and a second space, which is separate from the first space and forms an environment of the installation, wherein the at least one pump unit is embodied as a selective oxygen pump, by which, independently of a prevailing gas mixture and as required, oxygen is selectively transferred out of the first space and into the second space or selectively transferred out of the second space and into the first space, which reduces or increases an oxygen concentration in the first space;
- at least one photobioreactor unit for receiving fed-in carbon dioxide (CO2), generating oxygen (O2) via photosynthesis and outputting oxygen (O2), wherein the photobioreactor unit is arranged in the first space, and
- at least one control and regulation unit for regulating an absolute oxygen partial fraction in the first space, outside a reaction area of the at least one photobioreactor unit, to no more than 20% by controlling a power source of the pump unit, wherein the control and regulation unit comprises a control electronics component and a sensor for monitoring the absolute oxygen partial fraction.

A transfer device with at least one pump unit for a defined gas transfer between a first, closed-off space of an installation and a second space, which is separate from the first space, wherein
- the at least one pump unit is embodied as a selective oxygen pump and comprises at least one zirconium oxide element for a selective transfer of oxygen (O2) out of the first space into the second space,
- the zirconium oxide element is embodied as a tube, which is closed on one end and forms a hollow space inside,
- the hollow space is connected to the first space but is closed-off from the second space, and the closed end of the zirconium element protrudes into the second space,
- the at least one pump unit further comprises a guiding tube protruding from the first space into the hollow space,
- the guiding tube is spaced apart from the zirconium oxide element and extends parallel to the zirconium oxide element to a point shortly before the closed end of the zirconium oxide element,
- the guiding tube serves for guiding gas flowing into the hollow space, and
- via the guiding tube, gas can flow into the hollow space, and gas situated in the hollow space flows in a gap of the hollow space, between the guiding tube and the zirconium oxide element, out of the hollow space to allow for circulation.
