Definitions

  • the present invention relates to a device for the digestion of wood-based materials according to the Preamble of the main claim as well as a procedure its implementation.
  • Such a generic device is known (US-A-3,741,863).
  • A serves in this device trained as at least one stuffing screw Transport device for transporting the Digestion material, this one in a Outer jacket arranged discharge opening radially is transported. Furthermore, the feed opening the first stuffing auger as Inlet opening (77) used for steam.
  • the disadvantage of this known device Need besides the stuffing augers Seals in the form of a rotary valve (72) in front of the Provide feed opening of the first stuffing screw and in the form of a cyclone separator after the last one To provide a stuffing screw, creating such facilities are expensive.
  • the object of the present invention is a Generic device and a method create a continuous and therefore simple and economical digestion of Enable wood-based materials.
  • the device can that is, both economically and ecologically Respect to be operated optimally.
  • digestion pressures from 2 to 11 bar Maintain overpressure, preferably in Range from 2 to 8 bar and especially in the range from 3 to 6 bar overpressure.
  • the digestion process from the filling with the crushed chipboard fragments up to completely digested, moist wood mass is done with several, at least three in a row switched snails.
  • This pressure tight Darning augers perform several functions: both the transportation as well as the continuous Crushing and hydrolysis of the pre-swollen Mass of wood on the one hand due to the friction of the particles to each other, and on the other hand the actual one takes place Digestion process by water, steam and Heat absorption within the pipe screw system.
  • a modular construction is possible, whereby several identical screws and also drive systems can be used, making the cost crucial reduced.
  • the first has proven to be useful Darning screw into which the material to be digested is introduced with preheated water fill.
  • a water temperature of approx. 20 ° C to 95 ° C can be used.
  • the screw transport within the plant enables a homogenization of the wood mass and about the constant rubbing together during the Transports a good and continuous Size reduction, which is a good surface wetting causes. This can cause the enthalpy of the steam to over the entire pipe length can be fully used, because the rubbing against each other always Detach loosened layers mechanically and underneath expose lying, not yet solved layers that then easily caught by the steam. About The process can process higher process pressures again be accelerated.
  • the exhaust gas heat can be used almost completely and is compared to discontinuous operation not lost according to the state of the art.
  • the heat the moist, open wood mass can can also be used by after leaving from the last screw conveyor shortest way into the dryer. Thereby heat loss and drying effort minimized.
  • stuffing snails are thus used, which make it possible during the Material transport a pressure in too build up transporting material.
  • Such Snails also known as stuffing snails are, for example, one-sided Snails, the outlet opening of which runs axially. she can be a progressive or degressive slope have, that is, the distances between the coils increase or decrease per turn.
  • the transport speed through the stuffing augers is different, it can depend on the Vary the number of stuffing screws used. at a larger number of stuffing screws can Throughput speed can be increased at a smaller number, it must be reduced in order to dwell time necessary for the digestion guarantee.
  • the digestion can generally follow a Residence time approx. 30 min, preferably 20 min are completely effected so that when using more than three stuffing screws the dwell time per Darning screw is only a few minutes. Across from conventional discontinuous digestion processes this means a significant shortening of the Digestion time.
  • the water temperatures can be 20 to 95 ° C.
  • the water causes in Interaction with the abandoned wood materials an additional seal for the digestion overpressure used compared to Outside atmosphere.
  • the first stuffing screw is advantageously turned on the feed side of the material with a high pressure lock equipped. On the exit side is one Pressure control is not absolutely necessary since here the pressure can drop to ambient pressure.
  • the stuffing snails all had one 400 mm in diameter and 2.5 m in length. The It was driven by an electric motor uniform power of 10 kW. The first Darning screw was with a high pressure lock Fill level indicator provided.
  • Chipboard material which had been comminuted to a particle size of approximately 8x8x20 cm 3 was introduced into the first stuffing screw.
  • the screw was filled with preheated water, which had a temperature of approx. 90 ° C.
  • the feed speed of the stuffing augers was like this controlled that a dwell time of approx. 5 min. resulted in each stuffing screw.
  • the third stuffing screw became saturated steam with a Pressure of 4 bar overpressure metered in.
  • the device shown in Figure 1 contains five in a row arranged augers 1, 2, 3, 4 and 5, which are driven by drive motors 6.
  • the axial exit area of each screw is axial Direction perpendicular to the entrance area of the flanged subsequent stuffing screw, whereby pressure-tight connections are used.
  • the Darning screw 3 contains a steam supply 7, the is connected to a saturated steam source (not shown).
  • the stuffing screw 1 contains a feed device 8 for entering the digestion material.
  • At the The end of the last screw 5 is either one Vapor suction device or a spring cover 9 arranged.
  • the device shown in Fig. 1 has overall five pressure or so-called stuffing screws 1, 2, 3, 4, 5, each by drive motors 6 are driven. At the first snail the supply of those that have preferably already broken Wood material pieces as material feed. At the last snail 5 is an end Dispensing opening provided with a spring cover.
  • the five stuffing screws are arranged one behind the other and serve both as a digestion container and as Transport device for the wood-based material pieces.
  • Each stuffing screw has a housing-fixed Outer jacket 10 and an arranged therein drivable shaft 11 arranged around it Coils 12 of a predeterminable slope. Between the gears of the spirals on the one hand and between the (inner) shaft and the (outer) outer jacket the particles are transported.
  • the stuffing snails 2, 3, 4, and 5 indicate when reproduced Embodiment the same, each other but possibly different slopes of the Spirals up.
  • the stuffing screw 1 has coils 13 changing diameter or pitch.
  • the pressure screw and the stuffing screw 3 are each arranged horizontally.
  • stuffing screws 2 and 4 are angled, preferably arranged vertically.
  • the individual stuffing augers are like this connected in series that the Wood material pieces in the axial direction (Transport direction) 14 of the stuffing screw from the Feed opening 15 in the outer jacket 10 to one frontal discharge opening 16 in the axial direction are transported, being between the Feed opening and the discharge opening in the outer jacket 10 in the stuffing screw 3, the inlet opening 7 for Steam is provided.
  • the stuffing screw 2 can with an inlet opening 17 for water, preferably Be equipped with hot water. All stuffing snails, or at least part of it can be heated be designed.
