Embodiment Construction

[0023] figure 1 The shown method is particularly suitable for green wastes such as grass. Said method is particularly advantageous, since with it a large part of the cellulosic fibers usable for papermaking can be obtained.

[0024] figure 1 Process flow shown figure 1 Among them, the first step process step 2 is drying treatment. Therefore, a rapidly rotating blade 3 is provided, which shreds the green waste transported on the conveyor belt 4 like a lawnmower.

[0025] A dry filter 5 is then attached to which the oversize 6 is returned. The regularly accumulated biomass 7 in the form of wood chips is transported away by truck 8, for example to a thermal power plant.

[0026] The undersize 9 is conducted to a high consistency pulper 10 where it is processed according to the Kappa effect. Simultaneously, the imported undersize 9 is cut by the spiral 11 equipped with blades, and the cut undersize 12 is screened out through the sieve plate 13 .

[0027] A pulper 10 is used...

Abstract

The invention relates to a method for processing biomass, such as in particular green waste containing wood, and a high density pulper having a spiral, wherein the green waste is treated in a continuously operated, bladed pulper and then the separated fibers are ground in a pulper ball mill.

Description

technical field [0001] The invention relates to a method for processing biomass, especially wood-containing green waste, and a high-consistency pulper with spirals. Contents of the invention [0002] The treatment of biomass in a pulper for the production of cellulose and wood pulp fibers for papermaking requires in particular a specific method because, on the one hand, the biomass must be intensively treated to facilitate the release of the cellulose fibers, and on the other hand this must be carried out The length of cellulose fibers suitable for papermaking can be obtained through the process. [0003] It is therefore the object of the present invention to provide a method for processing biomass with which fibers of a specific length and quality can be obtained, in particular for paper production. [0004] This task is achieved by a process for processing biomass, especially wood-containing green waste, in which the biomass is treated with a continuously operating, blade...
