Definitions

  • the present invention relates generally to lignocellulosic material processing but more particularly to an integrated unit for treatment and drying lignocellulosic material.
  • Wood or wood products are dried in ovens (kiln or dryers) regardless of the treatment that is done in other production units (usually pressurized cylinders). This production requires a lot of handling between the different equipment used. It can even happen that the wood has to return to the dryer after treatment. Which creates additional costs and time.

  • Applicant did file patent, US7,246,452, describing a method for heat treating preservative-treated wood, as well as patent US7754284, describing a method for treating lignocllulosic material, both patents being incorporated herein by reference.
  • Applicant did mention: "In a further embodiment, it will be appreciated that the wood may be treated during the drying process.
  • the preservative may be incorporated in the water vapor utilized to heat the wood.
  • the heating process may also be coupled with known processes for incorporating preservatives in wood".
  • this statement was rather theoretical and it was not so obvious to actually create an integrated unit for drying and treating lignocellulosic material.
  • Another advantage is to make it so that the material can be dried to a desired moisture content and be treated without having to move the material, drying can even be continued if necessary in the same integrated unit.
  • Another advantage is that the integrated unit allows the use of different compounds at different concentrations and/or a combination of compounds..
  • Yet another advantage of combining treatment in drying in an integrated unit is to greatly reduce the costs associated these two operations versus when they are done separately (reduced energy, handling, transportation, logistics, labor, etc).
  • Still another advantage of the integrated unit is to provide a sealed vessel (chamber) capable of sustaining high humidity and variable gas pressures and into which is placed a lignocllulosic material, and a compound in mist form.
  • the vessel or chamber provides dry heat so as to dry the lignocllulosic material while the compound is impregnated within the lignocllulosic material.

  • An integrated unit (10) is comprised of a chamber (12) having three walls (14), a doorway (16), a ceiling (18), and a floor (20) that slopes towards a collecting basin (22). At least two walls (14) have tracks (24) onto which are installed a plurality of spraying nozzles (26). There is also at least one vent (29) to vent off excess humidity.
  • the floor (20) has rails (30) onto which rolls a carriage (32) supporting a racking system (34), which is generally nothing more than slats separating rows of lignocellulosic material (36) to be processed.
  • the chamber (12) also has fans (28), and heating elements (38) located inside a container (39) and over deflectors (40).
  • the heat comes either from electricity or from a hot fluid circulating inside coils. Alternatively, heat can be produced by direct flames from carbon based sources or bio mass. The heat for the fluid can come from electricity from carbon based sources, or bio mass.
  • the nozzles (26) are spraying a mist of fine liquid droplets that can travel in between rows and into the material (36). The mist consits in one of several possible substances which are admixed outside of the chamber (12), in a main mixing tank (32) which takes its ingredients from hoppers (34).
  • the ingredients are granular, they may be fed by gravity, if in liquid, either by gravity or by pump to the mixing tank. From the main mixing tank (32), the ingredients are pumped by a main pump (35) and directed towards the nozzles (26) by way of pipes (37).
  • the base ingredients can be granular salts mixed with water but several other ingredients can be used for the treatment. While the various substances are admixed, they are also heated so as to increase the dilution characteristics as well as not to cause a cooling effect upon entering the chamber (12).
  • a second pump (36) pumps it through a filter (38) to remove contaminants gathered during the process, then a secondary mixing tank (42), and then back through the main pump (35).
  • the material (36) can be dried to a desired moisture content and be treated without having to move the material (36). Drying can even be continued long after the treatment with the compound is completed, if necessary. Furthermore, the unit (10) allows the use of different compounds at different concentrations and/or a combination of compounds. [0038] The unit (10) greatly reduces the costs associated with the combination of these two stages of production (energy, handling, transportation, logistics, labor).
  • This unit (10) also has the advantage of recovering the water and the compounds used (residuals).
  • the other advantage is the recycling of the residuals. This recycling is not made in current dryers, but is mandatory in processing units for the protection of the environment.
  • the unit (10) can be fixed or mobile. It only requires connection (electricity, water and heat energy) to be operational. [0041] With respect to the above description, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

Au moins deux des parois ont des éléments de rail sur lesquels sont installées une pluralité de buses de pulvérisation. Au moins une ouverture d'évacuation est destinée à évacuer un excès d'humidité à l'intérieur de la chambre. Au moins un ventilateur et au moins un élément chauffant se trouvent à l'intérieur de la chambre. Un chariot roulant est configuré pour porter une charge de matériau lignocellulosique et est dimensionné pour s'insérer à l'intérieur de la chambre. Les buses pulvérisent un brouillard de liquide provenant de tuyaux externes, et le brouillard de liquide est constitué par la substance conçue pour traiter le matériau lignocellulosique.
