Method for protecting a fermentation vessel in a biogas plant as well as a fermentation vessel in a biogas plant

摘要

The invention relates to a method for protecting a fermentation container (5) of a biogas plant by means of the following steps: On the inside of the wall (9) of the fermentation container (5) at least one circumferentially circumferential path of a protective film (10) is arranged, which by means of several anchoring elements (14) is attached to the wall (9). On the protective film (10) in the region of the anchoring elements (14) and in the region of the joint (12) between the beginning and end of the protective film (10) media-tight a cover (22) welded. The invention also relates to a fermentation tank (5) for a biogas plant, with a wall (9) made of concrete, which is at least in a gas exchange zone predamaged by aggressive media, and a protective film (10) in the interior of the fermentation tank (5) on the Wall (9) is mounted, wherein the protective film (10) is provided at its upper edge with a crown protector (30) which extends over the upper edge of the wall (9) to the outside, with a seal (16) between the lower Edge of the protective film (10) and the wall (9) is provided, and wherein a plurality of anchoring elements (14) are provided, with which the protective film (10) on the wall (9) of the fermentation container (5) is anchored, wherein the anchoring elements ( 14) are covered by a cover (22), which is welded to the protective film (10).
