Problems solved by technology

It is known to design the heat exchanger section and the separation section as separate units, this design has the disadvantage of requiring a large number of elements and connecting conduits
However, it has proven difficult, cost permitting, to provide such a unit as well as separate sections for the heat exchanger section due to the high pressures generated by a single unit

Embodiment Construction

[0023] Figures 1-4 disclose an apparatus for treating an essentially gaseous medium. The device comprises a precooler 1 , an evaporator 2 and a separation section 3 . The precooler 1 and the evaporator 2 together form a heat exchanger section.

[0024] In the following, the device will be described in relation to the drying of compressed air. It is to be noted, however, that the device can also be applied to the treatment of other gaseous media in which the liquid is separated by condensation.

[0025] The air to be treated is conveyed through an inlet 4 of the precooler 1 and through the precooler 1 , the evaporator 2 and the separation section 3 via a first channel 5 . The separation part 3 comprises an outlet 6 for the air, through which the air is output and conveyed via a conduit 7 to a second inlet 8 of the precooler 1 . Thereafter, the air is conveyed through a second channel 9 of the precooler 1 for heat exchange with the air entering the device, and is output throu...

Abstract

A device for treating a substantially gaseous medium includes a number of parallel plates (14) which are connected to each other and provided adjacent to each other in such a manner that they, via port holes in the plates (14), form a first channel (5) and a second channel (9, 9'). The first channel (5) is arranged to transport the gaseous medium, and the second channel, which is separated from but in heat transferring contact with the first channel (5), is arranged to transport a cooling medium for cooling the gaseous medium. At least a part (3) of the first channel (5) is arranged to separate liquid from the gaseous medium. The part (3) of the first channel (5) is formed by a plurality of plate interspaces between a part of the plates (14), wherein at least one of the plates (14), delimiting one of the plate interspaces, is arranged to be passed by the gaseous medium on both sides thereof.

Description

technical field [0001] The invention relates to a device for treating essentially gaseous media comprising a plurality of parallel plates which are connected to each other and arranged adjacent to each other in such a way that a first channel and at least one second channel are formed by means of the openings of the plates , the first channel is arranged to transport the gaseous medium; the second channel is separated from the first channel, but is in heat transfer contact with it, and is arranged to deliver a cooling medium for cooling the gaseous medium; wherein at least a part of the first channel forms a separation section and arranged to separate liquid from the gaseous medium. Background technique [0002] This device is used to dehumidify compressed air from a compressor before it is supplied to a pneumatic tool or machine. Therein, the supplied compressed air is firstly cooled by means of a heat exchanger section, after which the moisture of the compressed air is al...
