Abstract:
A drying plant, for drying wood, comprising a heat-insulated drying chamber with an internal space for drying wood, a furnace located near the drying chamber, facilities for supplying a drying agent from the furnace to the drying chamber, distinctive in that the bottom of the drying chamber is designed with two cavities horizontally arranged and separated from each other by a hermetic partition made of diathermic material, the lower cavity in the bottom of the drying chamber is designed for forced feeding of furnace gases into the lower cavity from an exhaust pipe of a furnace flue, the upper cavity in the bottom of the drying chamber is designed for feeding of the air heated in the furnace flue into the upper cavity; in the upper cavity, the heated air, used as a drying agent, is distributed among air distribution channels to interact with a material to be dried, located in specially arranged areas in the internal space of the drying chamber; besides that, a portion of air, cooled and humidified during drying, may be forcedly fed from the upper part of the drying chamber into the furnace flue, the plant is also equipped with a condensate cleaning unit located outside the drying chamber, the condensate cleaning unit is forcedly fed with furnace gases after they pass through the lower cavity in the bottom of the drying chamber, the condensate cleaning unit is also fed with a portion of air, cooled and humidified during drying, from the upper part of the internal space of the drying chamber for mixing up with furnace gases to form a condensate and for subsequent exhausting of purified air.
