Definitions
- Wood chip drying plant for drying wood chips and associated method for drying wood chips
- the invention relates to a wood chip drying plant for drying wood chips, with a furnace, a dryer for the wood chips and a return device for returning vapors in the dryer, wherein the return device comprises a Brüdenerhitzer and wherein the wood chip drying plant is designed to reduce existing in the vapor organic compounds before returning to the dryer.
- the invention relates to a method of drying wood chips, comprising the steps of (a) passing flue gas from a furnace to a dryer, (b) drying the wood chips in the dryer to form vapors, and (c) Returning at least a portion of the vapor to the dryer.
- wood dust is burned in the furnace usually.
- the resulting hot flue gases are in one
- the resulting vapor is fed to a cyclone and then partially returned to the mixing chamber.
- the dried wood chips are then mixed with glue and pressed into a wood-based panel.
- a disadvantage of such wood chip drying plants is that the wood chips produced from the wood shavings
- BESTATIGUNGSKOPIE th wood-based panels can release volatile organic substances.
- a further known hot gas production and drying of the wood chips takes place in the form that primarily wood dust is burned with its own combustion air supply in a combustion chamber.
- the approximately 900-volume flue gases of this combustion pass into a mixing chamber, in which the so-called return vapors, the false air for cooling and optionally external hot gas are introduced.
- the drying hot gases are adjusted to the necessary requirements (temperature of approx. 350 - 480 0 C, total volume flow and humidity) for introduction into the chip dryer.
- the hot gas volume flow or drying air volume flow treated in this way is sucked via the dryer drum by means of a suction draft fan.
- the wood chips are dried in direct contact with the hot gases.
- the induced draft fan conveys the total hot gas volume flow involved in the drying process to a filter system which is designed primarily as a cyclone separator but also as an electron filter.
- This filter system separates primarily only solid particles to a limited extent.
- a partial flow called backflow volumetric flow, is fed back to the aforementioned mixing chamber.
- the drying of the wood chips requires a balanced temperature, energy and volume flow balance, which must be adjusted depending on the product (chip size, throughput, humidity, type of dryer).
- the dried wood chips are separated after the dryer drum, mixed with glue and pressed into a wood-based panel.
- a disadvantage of such wood chip drying plants is that the wood-based panels produced from the wood chips can emit volatile, organic substances resulting from resins and terpenes.
- the hot gases for drying the wood chips take the resins and Terpene partly out of the wood.
- the best effect of this is achieved by the fact that the dryer hot gases at the inlet of the dryer are free of fiber of the same kind.
- the hot gases at the drier inlet are mixed by known methods with backbreaks, which have already taken part in the drying process. The mixing volume flow is thus reduced in the uptake of resins and terpenes.
- the dryer hot gases conducted into the dryer are made entirely of broths mixed with the exhaust gases from the combustion of primary fuels.
- the vapors are partially passed into the combustion chamber and here at about 850 0 C thermally treated.
- the further vapor fraction is passed through a tube bundle heat exchanger and heated here to about 380 to 450 0 C with simultaneous cooling of the (50 graden) hot gases from the combustion chamber.
- the vapors heated up via the heat exchanger are not thermally treated due to the temperature level.
- Serious disadvantages of this type of hot gas production with the tube bundle heat exchanger systems is low availability due to contamination of the heat exchanger surfaces. Only a part of the vapors goes through a thermal treatment. The combustion air for burning the primary fuel is sucked in externally. The thermal efficiency of the process is relatively unfavorable.
