CHAMBER FOR DRYING WOOD WASTE IN FLUE GAS ENVIRONMENT Russian patent published in 2023 - IPC F26B9/06 F26B23/02 

FIELD: drying equipment.

SUBSTANCE: device relates to chamber drying of wood and is intended for drying low-grade wood and uncrushed wood waste for subsequent thermal modification and production of crushed wood, as well as for use as fuel. The drying chamber is located above the source of flue gases, which is connected to it by a chimney pipe having a free outlet of flue gases into its lower internal part; at some distance from the bottom of the chamber between the inlet chimney opening and the stack of wood, a false bottom is located over the entire area of the chamber in the form of a uniformly perforated screen, designed for spark extinguishing and uniform distribution of heat flow along the length and width of the stack; the upper part of the chamber for quick loading and unloading of the stack is equipped with a loose-fitting removable cover on heat-resistant seals with mounting loops for engagement and movement by lifting and transport machines and mechanisms; in the upper part of the drying chamber on one of the side walls on the opposite side relative to the lower inlet there is a chimney outlet and a chimney pipe connected to it; the inlet pipe is equipped with shut-off and control valves to regulate the flow of flue gases.

EFFECT: intensification of the drying process through the use of higher temperatures of the drying agent (flue gases), increasing economic efficiency by reusing flue gases and combining the processes of thermal modification and drying of low-grade wood and non-crushed wood waste.
