Problems solved by technology
[0007] Disadvantages of known devices for drying compressed gases without dissipation are that they are provided with a large number of pipes and valves for changing the pressure vessel upside down into regeneration and drying pressure vessels; they are large and expensive and have Complex, non-modular design, with a large number of variables to support, which drives up R&D, manufacturing and maintenance costs
[0008] In order to keep the existing equipment uncomplicated, three-way valves and / or four-way valves, which are more expensive and less reliable than traditional two-way valves, are sometimes used, which greatly reduces the overall operating reliability of the equipment
[0009] Another disadvantage of equipment with greater compressed gas drying capacity is that it is often not possible, or at least not economical, to find a three- or four-way valve that meets the desired temperature, pressure and flow requirements of interest

Embodiment Construction
[0028] Figure 1 shows a device 1 for drying compressed gas in a non-dissipative manner according to the invention, which device 1 is provided with a compressed gas supply source 2, which in this case is formed by a compressor and is connected with The first distribution device 3 is connected.
[0029] Said first distributing device 3 consists in this case of three parallel conduits connected to each other, namely a first conduit 4, a second conduit 5 and a third conduit 6, in each of which three conduits are respectively provided with two possible The shut-off valves 7-8, 11-12 and 9-10 are in this case formed in the form of controllable valves connected to a control system not shown in the figures, but this form is not essential.
[0030] Furthermore, the device 1 comprises a second distribution device 13, which in this case has practically the same dimensions and geometry as said first distribution device 3, and is also mainly composed of three parallel pipes connected to ea...

Device for drying a compressed gas in a non-dissipative manner, which mainly consists of a compressed gas supply (2), at least two pressure vessels (31, 32) with an input (33, 34) and an output (35, 36), and a take-off point (26), whereby the device (1) is additionally provided with a first distribution device (3) and a second distribution device (13) which is provided with one or several coolers (30) and whereby the device (1) can be controlled by means of nine or ten cut-off valves (7-12, 21, 22, 29, 38 and 40).
Description
technical field [0001] The invention relates to a device for drying compressed gas. [0002] In particular, the invention relates to a device for drying a compressed gas in a non-dissipative manner, in other words a device in which the heat of compression present in the compressed gas is used entirely or partly to regenerate the desiccant, and The entirety of the supply gas flow flows through the device in its entirety without any part of that gas being vented to atmosphere or fed back into the input of the device, resulting in a device that is more efficient than some existing devices. [0003] In particular, the invention relates to a device for drying compressed gas in a non-dissipative manner, which device essentially consists of a compressed gas supply source, such as in the form of a compressed air compressor, at least two pressure vessels with an input and an output, and for Composed of tap points for compressed gas consumers. Background technique [0004] Plants ar...
