Abstract

VASO DE IMPREGNAÇçO COM RELEVO LATERAL DE CONVERGÊNCIA E MÉTODO PARA A INJEÇçO DE CALOR NA CONVERGÊNCIA. A presente invenção refere-se a um vaso de impregnação incluindo: um recipiente de vaso incluindo uma entrada superior para receber o material celulósico, um orifício de descarga inferior para descarregar o material celulósico de uma seção de descarga do recipiente do vaso, uma seção de convergência interna ao vaso através da qual passa um fluxo do material celulósico no vaso, uma cavidade entre uma parede interna do vaso e a seção de convergência, onde a cavidade tem uma abertura inferior para o material celulósico no vaso e uma seção superior protegida do fluxo do material celulósico no vaso, e um orifício de entrada no vaso e abertura para a cavidade, onde o orifício de entrada pode ser conectado em uma fonte de líquido quente a ser adicionado no material celulósico no vaso.IMPREGNATION VASE WITH SIDE CONVERGENCE RELIEF AND METHOD FOR INJECTION HEAT INJECTION. The present invention relates to an impregnation vessel including: a vessel container including an upper inlet for receiving the cellulosic material, a lower discharge port for discharging the cellulosic material from a vessel container discharge section, a Internal vessel convergence through which a flow of cellulosic material in the vessel passes, a cavity between an internal vessel wall and the convergence section, where the cavity has a lower opening for the cellulosic material in the vessel and an upper section protected from the flow. of the cellulosic material in the vessel, and an inlet port in the vessel and opening into the cavity, where the inlet port may be connected to a source of hot liquid to be added to the cellulosic material in the vessel.
