Description

The invention relates to a sorption filter for sorbing and/or desorbing at least one substance for use in a sorption system, comprising several filter segments, each comprising at least one sorption layer containing sorption material and at least one support layer for the sorption material, and at least one connecting segment that connects two filter segments together. The invention further relates to a connecting segment for a sorption filter having several filter segments, with a first connecting area which can be connected to a first filter segment of the sorption filter, and a second connecting area which can be connected to a second filter segment of the sorption filter. Furthermore, the invention relates to a filter segment for a sorption filter, comprising several superimposed layered composites extending in a longitudinal direction, each comprising at least one sorption layer containing sorption material and at least one support layer for the sorption material. Furthermore, the invention relates to a sorption system for sorbing and/or desorbing at least one substance, comprising at least one sorption filter and a drive device for moving the sorption filter within the sorption system. The invention further relates to a method for operating a sorption plant, comprising the steps of: sorbing at least one substance in and/or on one or more filter segments of a sorption filter of the sorption plant, moving at least one filter segment of the sorption filter into at least one treatment area of the sorption plant, and desorbing the at least one substance from and/or from one or more filter segments of the sorption filter in the at least one treatment area. Furthermore, the invention relates to a manufacturing process for producing a sorption filter, comprising the steps of: producing or providing several filter segments, each comprising at least one sorption layer containing at least one sorption material and at least one support layer for the sorption material, and producing or providing at least one connecting segment. Sorption filters, particularly those designed as belt absorbers, are known in the prior art and can, for example, be configured as continuous filter belts. Such sorption filters can be used to implement sorption and/or desorption processes, for example, to sorb and/or desorb greenhouse gases such as carbon dioxide. In known sorption filters, the sorption material is typically located within a material holding area of the filter, for example, between two layers of the filter material. The sorption material is usually granular or powdery. Although enclosed within the material holding area, the sorption material can move freely within it. Such a sorption filter is described, for example, in the printed publication. US 7,377,966 B2 known. In sorption systems, a sorption filter is often moved along a predetermined filter path and deflected by deflection elements, particularly deflection rollers. This deflection exerts mechanical forces on the sorption filter, causing the sorption material within it to move and/or detach from the filter. Consequently, sorption filters known in the prior art are subject to high wear, particularly due to their insufficient mechanical strength. Furthermore, the movement of the sorption material within the material holding area can lead to a local reduction or even a local interruption of the sorption layer, which can severely impair the sorption properties of the filter. In sorption systems, sections of the sorption filter are typically moved into a treatment chamber before the chamber is sealed gas-tight from the environment. Since the sorption filter extends into and out of the treatment chamber, sealing problems have arisen, particularly at the interfaces. Furthermore, opening and closing the treatment chamber should ideally be abrasion-free or abrasion-free to prevent the sealing process from impacting the filter's service life. A gas-tight seal of the treatment chamber significantly increases energy efficiency in both the sorption and desorption processes. It also prevents parasitic leakage currents of fluids, substances, or energy, such as those resulting from heat or cold equalization or pressure equalization. The object underlying the invention is therefore to enable low-abrasion or abrasion-free operation of a sorption system in which one or more sections of the sorption filter extend at least temporarily through a treatment area to be sealed. The problem is solved by a sorption filter of the type mentioned above, wherein the sorption material is immobilized by means of at least one fixing agent and fixed to the at least one support layer. The sorption material is, for example, a sensitive, porous and/or granular sorbent. During sorption, at least one substance accumulates in and/or on at least one sorption layer. During desorption, the at least one substance accumulated in the at least one sorption layer is released from and/or on the at least one sorption
