A modular furnace, in particular for the oxidative stabilization of a carbon fiber starting material comprising a cuboidal furnace chamber, on the upper face of which first deflecting rollers are arranged in a mutually spaced and parallel manner and on the lower face of which second deflecting rollers are arranged in a mutually spaced and parallel manner such that the carbon fiber starting material runs upwards and downwards in a laterally adjacent and slightly spaced manner so as to meander vertically in the area of the furnace chamber. A carbon fiber inlet locking device and a carbon fiber outlet locking device are provided on the upper face of the furnace chamber, and an air guiding device is connected to the furnace chamber. A supply air portion of the air guiding device is connected to a vertical air inlet side of the furnace chamber, and a discharge air portion of the air guiding device is fluidically connected to a furnace chamber vertical air outlet side opposite the vertical air inlet side. The air guiding device has an air drive device between the supply air portion and the discharge air portion.

The present invention relates to an electrode heating device that dries an electrode. The electrode heating device comprises a heating body having a drying space through which the electrode passes, and a heating member that directly heats and dries a surface of the electrode that passes through the drying space to remove moisture from the electrode.

A treatment device (1) and a treatment method for a web (2) of endless material, in particular of a textile fiber material, preferably a non-woven fabric are provided. The treatment device (1) includes a treatment chamber (14) in which the moving web (2) is treated with a flowing gas, in particular air, an inlet (10) and an outlet (11) for the web (2), and a plurality of chamber regions (20-24). The plurality of chamber regions (20-24) are stationarily arranged on top and next to each other. The web (2) runs through the plurality of chamber regions (20-24). In the chamber regions (20-24), the gas, in particular the air, flows against and through the web (2) from one side.

The purpose of the present invention is to provide a drying device capable of preventing entanglement of a hollow fiber membrane in a drying chamber and preventing diameter reduction and flattening of the hollow fiber membrane. This drying device includes the drying chamber having a heating means disposed therein, a guide roll that causes at least two hollow fiber membranes (A) to travel inside the drying chamber, and at least two winding bobbins disposed outside the drying chamber. The drying device simultaneously dries at least two hollow fiber membranes (A) in the drying chamber while winding one hollow fiber membrane (A) on one winding bobbin. A rotation speed control means is attached separately to each of the at least two winding bobbins.

A drying device that includes a drying furnace having an inlet and an outlet, a drying unit installed inside the drying furnace and for drying a to-be-dried object, a number of upper and lower rolls alternately arranged at internal top and bottom portions of the drying furnace, and a roll driver connected to the plurality of upper and lower rolls and moving the upper rolls upwardly and the lower rolls downwardly, wherein after the to-be-dried object is transferred from the inlet to the outlet, the roller driver moves the upper rolls downwardly, moves the lower rolls upwardly, or moves the upper rolls downwardly and the lower rolls upwardly.
