Definitions

  • the invention relates to a method for drying wood chips according to the preamble of claim 1.
  • the wood chips are introduced into a substantially cylindrical drying container from above and withdrawn at the bottom, and in the drying air from below via a double bottom with perforated perforated plate is injected countercurrently into the drying tank.
  • Moist wood chips are often delivered at the price per bulk space meter without taking into account the actual calorific value of the delivered material. For example, the same amount of money is paid for moist or dried wood chips.
  • the disadvantage of this heterogeneous fuel is the relatively high water content in the wood, which strongly influences the calorific value. In order to improve the calorific value of the wood or to remove the water with simple methods, there are different drying methods with varying degrees of success.
  • the aim of the invention of the continuous continuous dryer in a round silo or even in a square shaft is the cost-effective removal of the ballast "water in wood chips" to produce a high-quality fuel and avoiding the waste of energy wood for the energy consumption of water evaporation in the firebox.
  • This drying process based on the convection flow of non-saturated hot air allows the recovery of low-temperature waste heat from various processes that are otherwise rarely used. Dried wood chips can save up to 20% of fuel when generating energy. As wood prices rise, so does the demand for economical drying of the wood.
  • the shows GB 103 699 A a device for drying cereals, which is not present here in the form of a bed, but essentially in free fall.
  • EP 1 559 979 A2 describes an apparatus and a method for the controlled drying of a free-flowing bulk material, which can trickle out of the drying container via a removal device arranged in a tapered end.
  • Other drying devices are from the DE 25 46 913 A , of the US 4,750,273 A , of the US 1,274,548 A , of the SE 529 255 C and the SU 1 216 267 A known. All these devices according to the prior art and the methods carried out with these devices are not specifically tailored to the problem that exists when drying wood chips. In contrast to grain or other granular materials, coarse heterogeneous wood chips have an irregular shape and a varying size distribution. Accordingly, special attention must be paid to a uniform distribution of the drying air in the drying container.
  • the natural drying is used by the self-heating of the wood chips in a heap heap without technical aids.
  • Hot air drying offers the methods of hot air drying, which reduce the drying time of the wood chips, the substance degradation and the formation of fungal spores with higher air temperatures and with the higher water absorption capacity. Hot air drying, however, requires high investment for the technical effort.
  • the methods of discontinuous operation are the stationary or mobile batch dryers.
  • the disadvantage of this drying technique is the high temporal manipulation effort for the filling and emptying of the boxes and containers, which is mainly associated with costs for personnel and machine use.
  • a uniform drying of the wood chips due to the formation of moisture zones is not given.
  • a time for a certain, uniform degree of drying or final moisture is therefore not possible.
  • the bulk material is dryer in the lowest layer of the hot air supply than at the upper layer due to the condensation processes.
  • the surface of the chippings-filled set dryer is not just filled, cause the different flow resistance inconsistent moisture in the wood chips in the upper layers.
  • the continuous drying processes include, in particular, the drum dryer, the contact dryer and the belt dryer, the wood chips being conveyed continuously through the dryer.
  • the hoeing material which has been lifted and mixed by means of lifting buckets, flows around a stream of hot air. Due to the high cost of heating the chips at temperatures up to 1,000 ° C and due to the exhaust air purification measures due to the odor and pollutant emission values, this method is used industrially only for certain applications.
  • the drying of fine free-flowing or voluminous bulk material takes place indirectly with tube bundles heated to a high temperature.
  • This is a rotating tube bundle with lifting and transport blades, whose heating coil is heated with steam and additionally through Injection of preheated air is operated. Due to the high expenditure on energy as well as for the observance of emissions (dust, odors, swaths) these processes are used industrially only.
  • the belt dryer uses much lower drying temperatures.
  • the drying of the wet chips takes place on a ventilated fabric belt moving forward.
  • the drying air flows through the conveyor belt and the layer thickness of the wood chips, which is applied evenly distributed on the tape.
  • the advantage of this mostly industrial application lies in the gentle drying by the use of low-temperature process heat and by the lower emission values.
  • the belt dryer is particularly suitable for drying fine wood chips and sawdust.
  • a uniform degree of drying can not be achieved.
  • Disadvantages of this drying process are the relatively high acquisition costs and the operating costs. These are above all the higher costs for the energy for preheating and drying the materials and the investment of the strip length, which determine the degree of drying or the final moisture content in a certain time unit.
  • a long residence time of the wood chips at low-temperature drying air is not possible for belt dryer for economic considerations.
  • a somewhat more efficient design of the belt dryer is the Schubwendrockner, with additional turning facilities (shovels or springs) to ensure loosening of the wood chips on the belt to about 40 cm dump height in a continuous process.
  • Dry, largely unsaturated warm air is generally used to dry bulk and other goods. Via the convection of the dry air flow, the escaping water from the material to be dried is taken up by the warm air to saturation, which is discharged from the drying system as saturated exhaust air.
  • various methods and devices for drying are used for this purpose. These are mostly container vessels in cylindrical or shaft form, ventilated floors of grid or perforated lock plate on which the drying material rests, various discharge devices such as screw conveyors, moving floors, suction, tilting devices, etc. and to control the drying processes corresponding program controls.
  • the basis of the invention of the continuous round-bottom continuous dryer forms the stationary batch dryer in the form of a container drying, designed as a box with a ventilated double bottom air cushion with perforated bottom, in discontinuous operation.
  • the container box is loaded with wet-moist wood chips by means of a wheel loader, the uneven connected to the air connection of the double floor via a flexible warm air hose so long vented with hot air until the entire contents of the wood chips dried.
  • the largely dried wood chips are emptied in the container by means of a Koppstrom for refilling and drying or seduced via a mobile traction device as a car dryer (mobile set dryer) for recovery.

  • the box or container is filled with fresh wood chips for drying according to a logistics concept and transported away again after drying.
  • the grain material to be dried is also usually guided from top to bottom in accordance with the gravitational effect, and the warm drying air is blown in from bottom to top via a fan below a perforated bottom.
  • Another drying process for drying grain in the hot air stream describes the GB 103 699 A , A device in which the grain is thrown from a rotating plate in the cylinder vessel, which is dried in free gall in countercurrent with warm hot drying air to the bottom of the cylinder vessel and is discharged by means of a screw conveyor.
  • a steam heater is used for generating hot drying air in countercurrent.
  • the temperature and humidity of the saturated air become continuous to control and control the dryer system measured.
  • sample grains are continuously removed and the moisture in the grain is determined capacitively digitally.
  • a computer program monitors the measurements and controls the drying process to optimize energy efficiency.

  • a forward pressure is exerted on the screw conveyor in order to be able to discharge the bulk material lying over the entire surface of the silo bottom evenly.
  • the screw conveyor With the screw conveyor, the bulk material lying above the ground is pulled into the middle through an opening and transported away.
  • Another drying method is according to DE 25 46 913 A1 the Siebêttrockner or Siebêtsichter, in which for drying and screening of sticky compost waste and for the decomposition of organic and inorganic substances, a cylindrical drying container is used with a sieve bottom for blowing hot air to produce a fluidized bed.
  • the material to be separated which is supplied centrally via a rotary valve, is distributed and ground on the sieve plate via an agitator. By blowing in warm drying air upward gas flow they are to agglomerate agglomerated organic components.
  • the material introduced as compost and refuse is set into rotary motion by the circular movement of the agitator above the level of the sieve plate, whereby the components are subjected to attrition and dissolution. Heavy fractions are discharged upwards via the low height to the overedge via the rotary valve, the fines over the bottom of the sieve and the light dried fractions in the fluidized fluidized bed at high flow rate.
  • the object of the present invention is to further develop the known processes so that wood chips can be dried efficiently and cost-effectively, whereby the available heat is utilized in the best possible way.
  • the solution of the invention is the further development of the simple design of stationary batch dryer, however, the findings of the drying technology are combined with the experience of the technique of continuous feeding and application of bulk material.
  • This concept of the invention is a cost effective alternative and allows continuous and efficient drying of wood - wood chips or bulk material under specification of the desired degree of dryness or final moisture with low, unsaturated drying air temperatures, which are otherwise hardly used.
  • the continuous through-flow dryer has a cylindrical shape or even a square shaft shape and allows up to a filling height of about 5 meters space-saving installation, with all connections to the dryer variable designable.
  • the bulk material to be dried is passed in countercurrent from top to bottom and the warm drying air from bottom to top. To ensure a sufficient dwell time, the removed dried bulk material is immediately re-supplied or supplemented with the same amount of undried bulk material.
  • the diameter and the overall height or the size of the drying vessel depends on the throughput with moist bulk material, which represents a function of the hot air temperature air quantity and sufficient residence time in the drying vessel depending on the input moisture and end moisture requirement.
  • a multi-stage heating coil for increasing the hot air temperature or for increasing the dryer output is activated for reheating.
  • the technical solution for drying heterogeneous bulk material from wood chips is in contrast to the very complex systems of continuous dryer (drum contact and belt dryer) and as a comparison to the unsuitable, mentioned dry-grain method for free-flowing bulk material with the subject invention of the method and apparatus for continuous through-flow dryer in a round silo is achieved by mixing fresh undried wood chips in a fully filled container, eg in the form of a cylinder or shaft warm drying air with a sufficient residence time in countercurrent is ventilated until the on the perforated hole bottom resting chips with the determined degree of drying can be discharged dried.
  • the wood chips dried over the perforated hole bottom are carried out according to the predetermined and measured degree of drying by means of a silo discharge consisting of a screw mill or chain cutter.
  • a free-running over the perforated ventilated silo bottom milling auger or chain cutter conveys the heterogeneous-coarse wood chips into the silo center, where it drops down through an opening on the rotating tower in the form of a conical cap and is transported by a conveyor belt.
