摘要:
An adsorption drying apparatus, in particular for drying a compressed gas, includes an adsorption chamber (11) having a plurality of adsorption conduits (101) containing an adsorption material (123), a first feeding line (106) and a first discharging line (109) disposed at a first end (111) of the adsorption chamber (11), and a second feeding line (108) and a second discharging line (107) disposed at a second end (112) of the adsorption chamber (11). The adsorption chamber (11) is rotatable with respect to the feeding and discharging lines (106, 107, 108, 109) so that the adsorption conduits may be fluidically connected in temporal alternation, wherein the gas is dried in a drying sector (102), and the adsorption material (123) is regenerated in the regeneration sector (103). The first feeding line (106) is configured such that the gas stream to be dried may be fed to the regeneration sector (103) as a full flow. The second discharging line (107) is in communication with the second feeding line (108) and thus forms a connecting line in which a condenser is provided, and a pressure increasing device (18) is provided within the connecting line so as to increase the pressure of the gas flowing from the second discharging line (107) to the second feeding line (108). A cooling stream may be branched off at the first (111) or second end (112) of the adsorption chamber (11), as need be, to cool the adsorption chamber (11) within the cooling sector (119). The regeneration sector (103) and the drying sector (102) are connected in cascade for a serial through-flow, such that the gas stream fed to the drying sector (102) essentially completely corresponds to the gas stream discharged from the regeneration sector (103), optionally including the gas stream discharged from the cooling sector.

A refrigerant dryer, in particular a compressed air refrigerant dryer, is provided for drying a gaseous fluid while cooling the gaseous fluid using a refrigerant. The dryer includes a pressure fluid-refrigerant agent-heat exchanger (30) in which a cooling of the gaseous fluid takes place directly or indirectly by a refrigerant conveyed in a primary loop (16), one or more refrigerant compressor/compressors (24) for operating the primary loop, and a cold accumulator (13) with an accumulator-side heat exchanger (20) which couples an accumulator discharge fluid to a cold accumulator medium (14). The pressure fluid-refrigerant agent-heat exchanger (30) and the cold accumulator (13) are fluidically connected or can be brought into fluidic connection via a discharge loop (15) for an accumulator discharge fluid. The cold accumulator (13) is arranged, relative to gravity, above the pressure fluid-refrigerant agent-heat exchanger (30), in such a manner that the heated accumulator discharge fluid is conveyed through the discharge loop (15) for cooling in the cold accumulator (13), is cooled there, and subsequently re-conveyed to the pressure fluid-refrigerant agent-heat exchanger (30).

A method is provided for applying a cover layer (9) to a net structure (4) to be used for medical purposes, in particular a thrombosis filter. The net structure (4) is applied to a planar substrate (1) that covers openings (5) of the net structure on one side, wherein the openings (5) across the uncovered side are filled with a sacrificial material (7), in particular copper. The net structure (4) is lifted from the substrate (1). A cover layer (9) is deposited on the surface previously covered by the substrate, and the sacrificial material (7) is removed.
摘要:
The present invention provides a process for controlling the cooling phase of a container to be cooled for a heat-regenerating adsorption system with the following process steps: definition of a cooling phase cut-off temperature as a function of at least one parameter which is characteristic of the cooling process, recording the outlet temperature of a cooling fluid emerging from the container to be cooled by means of an outlet temperature recording device, and termination of the cooling phase when the recorded outlet temperature of the emerging cooling fluid falls below the defined cooling phase cut-off temperature. The present invention also provides a device for a heat-regenerating adsorption system for controlling the cooling phase of a container to be cooled in accordance with this process.
