Title:
DRYING PLANT AND METHOD FOR DRYING WOOD
Document Type and Number:
WIPO Patent Application WO2001031270
Kind Code:
A3
Abstract:
The invention relates to drying equipment and can be used in wood and wood treatment industries, etc., whenever parameters and procedures necessary to dry materials such as wood are used. The invention allows the drying process to achieve a higher degree of environmental protection, a larger product output and power saving features on the account of the following design of the plant: the drying chamber (1) which contains the material to be dried includes a bottom (4) which has two cavities (5, 6); hot combustion products are injected into one of these cavities (5) from the flue pipe (9) of the furnace which is used to burn wood waste; hot air is supplied into the other cavity (6), whereby said air is heated in pipes which are located inside the flue (9), and is used as a drying agent. The hot drying agent is supplied from the cavity (6) in the bottom and circulates through distribution channels in the lower part of the drying chamber (1) where it passes through the material which is to be dried and rises in the top portion of the internal open space of the drying chamber (1). From that point, one part of the drying agent is fed into a closed circuit in the flue (9) of the furnace and is heated therein, and the other part of said drying agent is directed into a condensation cleaning unit (11) where it is mixed with furnace gases and purifies said gases by condensation.
