Abstract

LA INVENCION ABARCA UNA CAMARA (12) DE EXPANSION, DENTRO DE LA CUAL LOS PRODUCTOS (16) FUNDIDOS FLUYEN EN EL CASO (NO PROBABLE) DE UN FALLO DE UN RECIPIENTE (4) DE REACTOR A PRESION. LOS PRODUCTOS (6) FUNDIDOS SON ENFRIADOS EN ESTA CAMARA (12) DE EXPANSION POR MEDIO DE UN REFRIGERANTE (19) GUIADO A LA CAMARA. LA INVENCION PROPONE QUE SE PONGA PARTICULAR ATENCION A PREVENIR QUE EL SUELO (24) DE LA CAMARA (12) DE EXPANSION LLEGUE A ESTAR DEMASIADO CALIENTE. PARA ESTE OBJETIVO, UN SISTEMA (26) DE REFRIGERACION CON UNA MULTIPLICIDAD DE CANALES (28,30) REFRIGERANTES ESTA COLOCADO EN EL SUELO (24) DE LA CAMARA DE EXPANSION. INMEDIATAMENTE DESPUES QUE LOS PRODUCTOS (16) FUNDIDOS HAN EMERGIDO DEL REACTOR, EL REFRIGERANTE (19) FLUYE DE FORMA AUTOMATICA DENTRO DE LOS CANALES (28,30) REFRIGERANTES DE TAL MODO, QUE LOS PRODUCTOS (16) FUNDIDOS SE EXTIENDEN DENTRO DE LA CAMARA (12) DE EXPANSION SIENDO INCLUSO REFRIGERADOS DESDE ABAJO.
