Abstract
Wynalazek dotyczy sposobu suszenia biomasy drzewnej w suszarni tasmowej, w którym zassane z otoczenia przez wentylatory powietrze ogrzewa sie w zainstalowanych nad komora suszenia wymiennikach ciepla zasilanych energia cieplna wytwarzana w biomasowej kotlowni, wilgotna biomase drzewna dostarcza sie w sposób ciagly do komory suszenia, w której w trakcie przesuwania warstwy biomasy drzewnej na perforowanym tasmowym przenosniku miesza sie ja i suszy ogrzanym powietrzem przechodzacym przez warstwe biomasy drzewnej od góry do dolu. Sposób charakteryzuje sie tym, ze powietrze z otoczenia zassane przez wentylatory (5) usytuowane na obudowie (4) komory suszenia (2) ponizej tasmowego przenosnika (3) ogrzewa sie wstepnie w zaleznosci od jego temperatury o 10°C do 20°C w pierwszej grupie wymienników ciepla (8) zasilanych energia cieplna odzyskiwana przez instalacje odzysku ciepla (9) z gazów spalinowych wytworzonych w procesie spalania w biomasowej kotlowni (7), a nastepnie ogrzane powietrze przepuszcza sie przez odpowiadajaca liczbowo pierwszej grupie wymienników ciepla (8) i polaczona z nia druga grupe wymienników ciepla (10) zasilanych energia cieplna wytwarzana bezposrednio w biomasowej kotlowni (7) doprowadzana do tych wymienników (10) w postaci podgrzanej mieszaniny wodno-glikolowej, w których przy temperaturze mieszaniny wodno-glikolowej na wejsciu wynoszacej od 65°C do 75°C, a na wyjsciu od 45°C do 55°C ogrzewa sie powietrze do temperatury od 55°C do 64°C, po czym powietrzem tym w komorze suszenia (2) suszy sie od góry do dolu przemieszczajaca sie na tasmowym przenosniku (3) warstwe biomasy drzewnej o wysokosci 10 cm, która po przemieszaniu wyrównuje sie ponownie do wysokosci 10 cm za pomoca dwóch przeciwbieznych srubowych przenosników (14) zamontowanych nad tasmowym przenosnikiem (3) za urzadzeniami mieszajacymi biomase.The invention relates to a method of drying wood biomass in a belt dryer, in which the air sucked in from the environment by fans is heated in heat exchangers installed above the drying chamber fed with heat energy generated in the biomass boiler room, moist wood biomass is continuously supplied to the drying chamber, in which while moving the wood biomass layer on the perforated belt conveyor, it is mixed and dried by heated air passing through the wood biomass layer from top to bottom. The method is characterized by the fact that the ambient air sucked in by the fans (5) located on the housing (4) of the drying chamber (2) below the belt conveyor (3) is preheated, depending on its temperature, by 10 ° C to 20 ° C in the first a group of heat exchangers (8) supplied with heat energy recovered by heat recovery installations (9) from flue gases produced in the combustion process in a biomass boiler room (7), and then the heated air is passed through the number 1 heat exchangers corresponding to the first group (8) and connected to there is a second group of heat exchangers (10) supplied with heat energy generated directly in the biomass boiler room (7) fed to these exchangers (10) in the form of a heated water-glycol mixture, in which at the water-glycol inlet temperature from 65 ° C to 75 ° C, and the output from 45 ° C to 55 ° C, the air is heated to a temperature from 55 ° C to 64 ° C, then the air in the drying chamber a (2) is dried from top to bottom moving on the conveyor belt (3) 10 cm high layer of wood biomass, which after mixing again equalizes to a height of 10 cm with the help of two opposing screw conveyors (14) mounted above the belt conveyor ( 3) behind biomase mixing devices.
