Problems solved by technology

[0018] The disadvantage of this is that it may happen that part of the hot gas used for regeneration leaks towards the other compartment where the drying gas is discharged, thus undesirably raising the dew point of the drying gas

Embodiment Construction

[0042] exist figure 1 , a device 1 for drying a gas according to the invention is shown, which essentially consists of a dryer 2 using a container 3 inside which has a preferably cylindrical, rotatably mounted rotor 4 , the rotor has a regenerable desiccant 5 inside, such as silica gel, etc., and the desiccant is located, for example, in an axially extending channel in the rotor 4 .

[0043] Such as figure 2As shown, the container 3 comprises at least three compartments at the first end (in this case, at the top) of the rotor 4, respectively a first, second and third compartment, the first compartment 6 Comprising a main outlet for the gas to be dried (referred to below as the main flow), the second compartment 7 comprises an inlet for a cooling flow, and the third compartment 8 comprises an inlet for a regeneration flow which can, for example (but not necessary) is split with the gas to be dried.

[0044] At the other end of the rotor 4, the second end, at figure 2 Cent...

Abstract

A device for drying a gas, said device being provided with a dryer (2) comprising a container (3) divided at a first axial end of said rotor (4) for respective At least three compartments directing at least three air streams, a main stream, a regeneration stream and a cooling stream, wherein a first compartment (6) comprises an outlet for said main stream and a second compartment (7) comprises an outlet for said cooling stream flow inlet, a third compartment (8) includes an inlet for said regeneration flow; and said container (3) includes at least two compartments at a second axial end, that is, includes A first compartment (9) of the inlet of the main flow and a second compartment (10) comprising outlets for said cooling stream and said regeneration stream.

Description

technical field [0001] The present invention relates to devices for drying gases, more particularly compressed gases. [0002] In particular, the invention relates to a device comprising a dryer using a container having a rotatably mounted rotor inside containing a desiccant. Background technique [0003] There are known devices for drying gases comprising a dryer comprising two zones, namely a drying zone and a regeneration zone, through which the majority of the gas as main flow is led after first cooling For drying, the regeneration zone regenerates the saturated desiccant by passing a stream of hot regeneration gas therethrough. [0004] Said drying zone and regeneration zone are obtained by forming compartments in containers located at the two ends of the rotor, one compartment at the first end forming the inlet to the drying zone, at the second end of the rotor opposite to the inlet An outlet for said main flow is provided at two ends, and the other compartment is pr...
