[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] For example, Figures 1-6As shown, the biogas drying device provided by the embodiment comprises a drying pipe 1, water-absorbing particles 3, and two groups of joint assemblies 2. The water-absorbing particles 3 are filled in the drying pipe 1. The two groups of joint assemblies 2 are respectively connected to two ends of the drying pipe 1. As can be understood by those skilled in the art, the joint assemblies 2 are used to be connected to external pipelines. After the biogas mixed with water vapor passes through the drying pipe 1, the water vapor is absorbed by the water-absorbing particles 3, and the dried biogas is discharged from the other end of the drying pipe 1. The device has a simple structure and can efficiently remove water vapor in the biogas. The water-absorbing particles 3 are prior art in the field, and thus will not be described here.
