Embodiment Construction

[0030] image 3 , 4, 5 and 6 show in different stages a first embodiment of the device for drying compressed air according to the invention. Moist compressed air 8 (compressed from ambient air by a compressor 9 not belonging to the device) enters the device through inlet 1 . The compressor 9 is not equipped with a subcooler, so that the incoming moist compressed air 8 is warmer than the ambient air. An inlet line 10 branches off directly behind the inlet 1 and can be connected on both sides to each of the two parallel absorption containers 3 , 4 by means of a plurality of adjustment mechanisms 11 .

[0031] exist image 3 In the operating situation shown, the absorption vessel 3 on the left is in the absorption phase, and the absorption vessel 4 on the right is in the regeneration phase, more precisely in the desorption phase. For the desorption, the heat of the still-to-be-dried compressed air 8 is first conducted along the intake line 10 through the right-hand absorption v...

Abstract

The invention relates to a facility for drying compressed air with at least two parallel-connected, drying agent-filled absorption containers (3, 4) which alternately are driven in absorption or regeneration mode. The drying agent dries the compressed air (8) in absorption mode, the moisture-laden drying agent is dried first by desorption and then cooled while in regeneration mode. The drying agent is dried with the heat found in the dried, moist compressed air (8). To increase the energy efficiency of the facility and the quality of the dried compressed air (14), the invention proposes that a stream (7) be branched off out of the dried compressed air after desorption is done in order to cool the absorption container (4) in regeneration mode and then to mix in the dried, moist compressed air after it has run through the absorption container (4) in absorption mode. This requires that a pump to increase pressure (17) be placed in the partial stream conduit(16) branching off from outlet line (15). This makes it possible to use the cooling phase as the second step of the regeneration process that can be carried out even if there is no airflow from the process.

Description

[0001] This application is the original application with the application date of May 2, 2007, the application number 200780023567.9 (the international application number is PCT / EP2007 / 003841), and the title of the invention is "Drying of compressed air using compressor heat to pass through the sealed regeneration cycle" divisional application. technical field [0002] The invention relates to a device for drying compressed air. The invention also relates to a method for regeneration of an absorption vessel of such a device. Background technique [0003] In current installations at least two parallel desiccant-filled absorption vessels are operated alternately in absorption and regeneration operation. In the absorption operation the desiccant dries the compressed air to be dried, in the regeneration operation the desiccant is first dried by desorption and then cooled. Drying of the desiccant is achieved by utilizing the heat contained in the moist compressed air to be dried...
