Definitions
- the invention relates to a process for the treatment of biomass, in particular wood-containing green waste and a high-density pulp with a spiral.
- biomass in particular wood-containing green waste and a high-density pulp with a spiral.
- the process must be conducted in that suitable cellulose fiber lengths are achieved for papermaking.
- the invention is therefore based on the object to provide a method for the treatment of biomass, can be provided with the fibers of special length and nature, in particular for papermaking. [04] This object is achieved with a method for the treatment of biomass, in particular wood-containing green waste, in which the biomass is treated in a continuously operated, sized pulper and then the separated fibers are ground in a Pulperkugelmühle.
- the sized pulper is operated as a high-density pulp.
- An advantageous density in the sized pulper is therefore 10 to 20 GG.
- the speed of the knife relative to the biomass is of high relevance. Particularly good results were achieved with knife speeds of more than 10 m / sec relative to the biomass.
- the biomass has a high content of woody constituents
- a fast rotating knife as in a lawn mower, followed bynsiebung together with the return of the upper grain can be used. This means that it will become a classic mill Used classifying system and, for example periodically separated the resulting biomass in the form of, for example, wood chips and fed, for example, a biomass cogeneration plant.
- biomass has wood components
- the biomass be heated under pressure.
- an autoclave can be used.
- continuous heaters water can be supplied and it can be drained steam to influence the processes during heating.
- the biomass is kept hot for several hours. If no steam is vented, it is sufficient to bring the biomass under pressure preferably to a temperature, for example between 100 ° C and 200 ° C, so that the biomass becomes soft and thus easier to treat.
- the present invention is based on the finding that it makes sense to use knives in a high-density pulp which have a particularly sharp cutting edge.
- Sharp knives such as, in particular, utility knife blades or other sharp blades, can be used as cutting edges.
- Figure 1 schematically shows a method with a mended pulper and a Pulperkugelmühle
- FIG. 2 schematically shows a method with a fitted pulper and two pulper ball mills.
- the method shown in Figure 1 is particularly suitable for green waste, such as grass. This method is very advantageous because it can be used to expose most of the cellulosic fibers that are useful in papermaking.
- the first process step 2 is a dry processing.
- a rapidly rotating blade 3 is provided, which comminutes the green section conveyed on the belt 4 like a lawnmower.
- the top grain 6 is returned.
- Periodically accumulating biomass in the form of wood chips 7 is disposed of by the carriage 8 and fed, for example, a heating plant.
- the undersize 9 is fed to the high-consistency-density pulp 10 and treated there according to the kappa effect. In this case, the supplied undersize 9 is cut with a mended spiral 11 and the cut undersize 12 is removed below a screen plate 13.
- the milled coil 11 of the reactor 10 is driven at high speeds to achieve high cutting speeds.
- a screen plate 13 is a perforated plate with hole diameters of about 1 to 4 mm, such as 1.5 mm, provided.
- the pulp is discharged as a cut undersize 12.
- the pulper 10 is operated in such a way as a reactor that the relatively long green fiber fibers are cut to a useful for paper production measure of about 5 to 6 mm.
- the second main process step is fibrillating grinding of the fibers in a continuous pulper mill 14.
- This pulper mill 14 has a hole diameter of about 2 mm in the perforated plate 15, a spiral 16 and Bullets 17, about have the density of plastic.
- the fibers are roughened in such a way that, for example, they provide a good bond with each other during later paper production.
- This second process step in the pulper mill 14 is preferably operated in two stages.
- the pulp to be ground is milled with the addition or flow of relatively little water until the desired strength increase has been established.
- the fibers are washed out of the ball pulp mixture using a relatively large amount of water.
- a sorting is performed in a slot sorter 19 having slots of ⁇ 0.3 mm in the sorting plate 20.
- the cleaned pulp 21 is then removed from the classifier 19, while the larger particles 22 are removed by means of the cart 23 opposite.
- the milled pulp 8 leaves the system for further use, especially for papermaking.
- the upper grain 39 in the pulper 31 with the augmented spiral 32 is fed to a second pulp ball mill 40, which has heavier grinding media 41, a spiral 42 and a screen plate 43. There, the upper grain 39 is subjected to a fiber-shortening, at the same time fumigating and fibrillating the woody constituents. Thereafter, the fiber fraction 44 leaves the system.
- a thickener between sliced pulper 10, 31 and pulp ball mill 14, 33, 40 can be placed anywhere between these units. Due to its washing properties, such a thickener extracts the non-paper components, such as ash, proteins, floury fines, colloids, etc., in order to separate them from the fibers already in an early process step and to recycle them to another utilization. Here comes the processing to cattle feed or also a fermentation to biogas in question.
- the diameters of the balls are 4 mm and above. For smaller balls of the order of 2 mm, too much fines are produced which hinder the process.
- the biomass is first pretreated in an autoclave for the treatment of woodcut, woody green waste or woodchips.
- the biomass is optionally maintained under the addition of water in an autoclave for several hours at about 120 ° C under pressure. In doing so, the wood becomes so soft that the further treatment can be carried out as in the case of a green section or together with a green section.
