Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA REDUCIR EL CONSUMO DE AGUA FRESCA Y DE ENERGIA EN UNA FABRICA DE PAPEL. EN EL PROCEDIMIENTO, SE INTRODUCE AGUA FRESCA EN LA FABRICA DE PAPEL PARA DIVERSAS NECESIDADES, Y SE UTILIZA UNA TORRE DE REFRIGERACION (100), POR MEDIO DE LA CUAL SE ENFRIA EL AGUA QUE SE HA CALENTADO PREVIAMENTE EN EL PROCESO DE FABRICACION DEL PAPEL. TODA EL AGUA FRESCA O UNA PARTE SUSTANCIAL DE LAS AGUAS FRESCAS DE LA FABRICA DE PAPEL SE INTRODUCEN EN EL PROCESO A TRAVES DEL SISTEMA DE AGUA DE LA TORRE DE REFRIGERACION. ADEMAS, LA INVENCION EXPONE UNA TORRE DE REFRIGERACION, EN LA QUE SE ENCUENTRAN UNA O VARIAS ENTRADAS (10) PARA QUE EL AGUA (W I N ) QUE DEBE ENFRIARSE PASE A LA TORRE DE REFRIGERACION (100), UNAS TOBERAS (13) O EQUIVALENTES PARA DISPERSAR EL AGUA QUE HA SIDO INTRODUCIDA Y QUE DEBE ENFRIARSE SOBRE UNOS FRENTES DE TRANSFERENCIA TERMICA, PIEZAS DE RELLENO Y/O CHAPAS DE RELLENO (15), QUE DISPERSAN EL AGUA QUE DEBE REFRIGERARSE, A FIN DE AUMENTAR LA SUPERFICIE DE CONTACTO ENTRE EL AGUA Y EL AIRE DE REFRIGERACION, UNA O VARIAS SALIDAS (17) PARA SACAR EL AGUA REFRIGERADA (W OUT ) DE LA TORRE DE REFRIGERACION (100), ASI CO MO SOPLANTES (23) PARA IMPULSAR EL AIRE DE REFRIGERACION (A SUB,IN -> A OUT ) A TRAVES DE LA TORRE DE REFRIGERACION (10 0). LA TORRE DE REFRIGERACION (100) ESTA COMPUESTA POR MODULOS DE ENFRIAMIENTO (30 L ...30 N ), CADA UNO DE LOS CUALES COMPRENDE LOS ELEMENTOS (10...23) ARRIBA MENCIONADOS, Y EL NUMERO (N) Y LA ALTURA DE DICHOS MODULOS DE REFRIGERACION (30 SUB,L ...30 N ) HAN SIDO ELEGIDOS DE ACUERDO CON LA EXIGENCIA DE CAPACIDAD DE REFRIGERACION, Y DICHOS MODULOS DE ENFRIAMIENTO (30 L ...30 N ) HAN SIDO INTERCONECTADOS MECANICAME NTE Y EN PARALELO, Y CONECTADOS DE FORMA SELECTIVA Y OPTIMA CON VISTA AL FLUJO (A IN -> A OUT ) DEL AIRE DE REFRIGERACION Y DEL FLUJO (W IN -> W OUT ) DEL AGUA QUE DEBE SER ENFRIADA.
