Abstract

"MéTODO PARA PRODUçãO E TRATAMENTO DE FIBRAS DE MADEIRA EM UMA PLANTA, E , PLANTA PARA PRODUçãO E TRATAMENTO DE FIBRAS DE MADEIRA". A presente invenção refere-se a uma planta e a um método para produção e tratamento de fibras de madeira em uma planta compreendendo uma parte de produção de fibras tendo um pré-aquecedor de aparas (1) e um batedor (2) para liberar fibras a partir de aparas de madeira. Uma tal planta e um tal método são incluídos como partes em um processo de produção contínuo de prancha e o objetivo é de reduzir as descargas de emissão de em primeiro lugar VOC e formaldeído, durante diferentes partes do processo bem como do produto acabado. O método compreende alimentação de aparas de madeira (A) ao interior de uma parte superior do pré-aquecedor de aparas (1), descarga de aparas de madeira (A) no fundo do pré-aquecedor de aparas em um transportador de parafuso (12) para o transporte adicional para o batedor (2), compressão das aparas de madeira em uma zona de compressão (15) no transportador de parafuso, suprimento de vapor (B) ao interior da parte inferior do pré-aquecedor de aparas para lavar aparas de madeira alimentadas na direção do contra-fluxo, descarte (8) dos gases de combustão na forma de emissões orgânicas, vapor e ar liberados na parte superior do pré-aquecedor de aparas, bem como descarte dos gases gerados durante a compressão através de uma saída (13) disposta na zona de compressão. A planta tem as partes correspondentes."METHOD FOR PRODUCTION AND TREATMENT OF WOOD FIBERS IN A PLANT, AND PLANT FOR PRODUCTION AND TREATMENT OF WOOD FIBERS". The present invention relates to a plant and a method for producing and treating wood fibers in a plant comprising a fiber producing part having a chip preheater (1) and a beater (2) for releasing fibers. from wood shavings. Such a plant and such method are included as parts in a continuous board production process and the purpose is to reduce emission discharges of primarily VOC and formaldehyde during different parts of the process as well as the finished product. The method comprises feeding wood chips (A) into an upper part of the chip preheater (1), discharging wood chips (A) into the bottom of the chip preheater in a screw conveyor (12). ) for additional transport to the beater (2), compressing the wood chips into a compression zone (15) on the screw conveyor, steam supply (B) into the underside of the chip washer preheater backfilled, discharge (8) of flue gases in the form of organic emissions, steam and air released at the top of the chip preheater, as well as discharge of gases generated during compression through a outlet (13) disposed in the compression zone. The plant has the corresponding parts.
