Problems solved by technology

[0007] The disadvantage of this dryer according to the above-mentioned patent application lies in the fact that by applying this method, the energy consumption is not optimized during the entire complete operating cycle of the dryer, since said method does not take into account the current state of the adsorption column, and Therefore the method is not efficient

Embodiment Construction

[0049] figure 1 An adsorption dryer 1 is shown, which in this case comprises two adsorption vessels 2 connected to a gas source 3 via a dryer inlet 4 . The adsorption dryer 1 is capable of removing moisture from the gas flowing through the dryer inlet 4 and provides dry and possibly cold gas via the dryer outlet 5 to an external network (not shown).

[0050] In the context of the present invention, it is understood that the adsorption dryer 1 may also comprise more than two adsorption vessels 2 or even only one adsorption vessel 2 .

[0051] Preferably, the adsorption vessel 2 comprises an adsorption material (not shown) capable of capturing moisture from the gas flowing therethrough.

[0052] In the context of the present invention, it is understood that adsorption may also include absorption.

[0053] Each of the two adsorption vessels 2 comprises an inlet 6 and an outlet 7 for allowing gas to flow therethrough. The adsorption dryer 1 also comprises a controller unit C an...

Abstract

The present invention is directed to a method for regulating the regeneration time of an adsorption dryer, the method comprising the steps of: subjecting the adsorption dryer (1) to an adsorption cycle; stopping the adsorption cycle after a preset adsorption time interval (T1); and subsequently subjecting the adsorption dryer (1) to a first regeneration cycle during a preset time interval (Time3);characterized in that: - maintaining the first regeneration cycle for an additional regeneration time interval (TE1) if said measured pressure dew point or relative humidity is higher than a predetermined pressure dew point or relative humidity threshold; and / or - stopping said first regeneration cycle if the outlet temperature (temp1) is higher than or equal to a predetermined temperature threshold, and, if the time frame in which the adsorption dryer (1) is subjected to said first regeneration cycle is greater than a minimum heat regeneration time interval ( THeat-min).

Description

technical field [0001] The invention relates to a method for regulating the regeneration time of an adsorption dryer, said method comprising the steps of subjecting the adsorption dryer to an adsorption cycle in which process gas is guided through the dryer inlet and moisture is adsorbed from the process gas; the adsorption cycle is stopped after a preset adsorption time interval; and subsequently, during a preset minimum heated regeneration time interval, by heating the regeneration gas before directing it through the dryer inlet The dryer is subjected to a first regeneration cycle. Background technique [0002] Adsorption dryers are often used in different applications requiring the flow of dry and cooled air. [0003] The challenge encountered is to maintain the low energy consumption of such adsorption dryers. Typically, the adsorbent material in a desiccant dryer becomes saturated and requires periodic regeneration. This is typically done by heating the regeneration ...
