- an air vortex is now generated with the driven by the drive motor 5 rotor 4, accelerated by the particles of the batch in addition to the direct shocks by the rotor 4 itself to speeds between 80 m / s and 130 m / s ⁇ and by impact stress be crushed.
- the resulting as a result of the impact stress products can be continuously or discontinuously sucked through the suction pipe 3 from the interior 2. Since the penetration depth of the suction tube 3 into the interior 2 is adjustable and since the suction tube 3 is vertically and horizontally ver ⁇ swiveled or displaced, the suction tube 3 can be adjusted so that only products are sucked with desired fiber sizes or fiber qualities. The pipe dimension and the design of the exhaust opening are further important factors. In a downstream cyclone 14 of Appendix 7, these extracted products are separated.
- products can be withdrawn but also discontinuously from the reactor 1 baffle, collected in a container 15 and a further use, for example, egg ⁇ ner thermal be supplied. It is also possible Return of the products A2 via a feed line 16 back into the impact reactor 1.
- the products are conveyed into a further gravity separator 17, such as a zig-zag separator, where they are separated into desired target fractions (C).
- a sieve can be used. Overscorn is thereby withdrawn from the heavy ⁇ force separator 17 or the screen in a container 18 and conveyed back by means of the metering device 13 for re-defibration in the impingement reactor 1.
- Another cyclone 19 is used to separate the target fractions (C) again.
- the thereby obtained target ⁇ grain can be fed to a buffer memory 20 and then through a metering a dryer 21 then.
- the target grain (Cl) is dried to a predetermined final moisture ⁇ activity.
- heat is used, which is obtained in the above-mentioned biomass power plant by burning eg.
- the grain portions 9 and the dryer 21 by means of the gas stream 23 / y is supplied.
- the target particle (Cl) eventually is present as a use finished product beispielswei ⁇ se in the form of a quantity of fibers as a primary or secondary raw materials in a hopper 22 of the system.
- the end product may, for example, fibers of 0.5 mm to 2.5 mm in length and have a diameter of 20 pm to 60 pm.
- a gas 23 with low oxygen content preferably a dry flue ⁇ gas
- a gas 23 with low oxygen content passed with a suitable temperature in the impingement reactor 1.
- a flue gas and heat side involvement in a biomass power plant and in particular in the above-mentioned biomass power plant in which the grain fractions 9 are burned, conducive.
- the quality and quantity of the good grain is continuously measured.
- an ultrasound measuring method is particularly suitable.
- the metering and thus the filling volume of the impact reactor 1 are regulated. The aim is to ensure a continuous production process possible at ent ⁇ speaking Gutkorn21 process control.
- the quality of the fibers produced in the impact reactor 1 depends on various factors, including the piece size, type of wood and the moisture ⁇ keitsgehalt and the bulk density of the starting materials, the degree of filling of the interior 2, the geometry and the volume of Interior 2, the formation of the rotor 4 and eventu ⁇ ell provided baffles, angles and distances of the rotor 4 from the walls of the interior 2, the Zentrifugalbeschleu ⁇ tion of materials, the supply and Abcertifiedorgane the impact ⁇ reactor 1, the air circulation and Flow through the interior 2, and the average distance of Parti ⁇ angles in the interior 2 include. It has been found that in particular the filling degree of the impact reactor 1 as a control or control variable is be ⁇ Sonders. Favorable filling levels in the range of 3-6%.
- the suction pipe 3 is a pipe which is connected to a suction hose 35.
- the suction pipe 3 held by a holder 36 pierces above the bottom 37 of the impact reactor 1 its wall, which surrounds a cover plate 38 facing away from the interior 2 and a screen plate 39 facing the interior 2.
