Abstract
La presente se refiere a un intercambiador de calor (1) para el enfriamiento rápido del gas de combustión emanado por las plantas siderúrgicas, que comprende: una estructura de soporte (2) de al menos un módulo (100) que, a su vez, comprende un colector de entrada (3) del gas de combustión y un colector de salida (4) del gas de combustión, que están mutuamente opuestos y alineados; una pluralidad de paneles (5) que se extienden entre el colector de entrada (3) y el colector de salida (4) y que están mutuamente superpuestos a una distancia definida en donde los pares de paneles adyacentes (5) definen canales de flujo (6) del gas de combustión que están cerrados lateralmente por hombros (7) y que tienen en los extremos opuestos, respectivamente, una apertura de entrada (8) en comunicación con el colector de entrada (3) y una apertura de salida (9) en comunicación con el colector de salida (4), y conductos de circulación (10) de un fluido de enfriamiento asociado con los paneles (5); primeros medios de cierre selectivos (14) de las aperturas de entrada (8) de uno o más de dichos canales (6) y segundos medios de cierre selectivos (15) de las aperturas de salida (9) de uno o más de dichos canales (6), en donde cada uno de dichos canales (6) está cerrado en forma lateral por un respectivo par de hombros (7) de los cuales, al menos uno es de tipo desmontable.Reivindicación 17: Un aparato (200) para el tratamiento del gas de combustión emanado por las plantas siderúrgicas, caracterizado porque comprende un grupo (201) para capturar el gas de combustión que sale de un horno de arco eléctrico (202) o de un convertidor; un grupo (203) para pretratar el gas de combustión capturado; un intercambiador de calor (1) de acuerdo con una o más entre las reivindicaciones 1 y 16, cuyo colector de entrada está conectado a la salida de dicho grupo de pretratamiento (203) y cuyo colector de salida está conectado a un grupo para succionar gas de combustión; un grupo de postratamiento (204) del gas de combustión que sale de dicho intercambiador (1); un circuito (205) del fluido de enfriamiento que funciona en dicho intercambiador, en el cual, a lo largo de dicho circuito, se coloca un grupo de enfriamiento (206) del fluido de enfriamiento que sale de dicho intercambiador (1), con una recuperación del calor sustraído de dicho fluido de enfriamiento. Reivindicación 21: Un método para tratar gas de combustión de plantas siderúrgicas, caracterizado porque comprende los pasos que consisten en lo siguiente: capturar el gas de combustión que sale de un horno de arco eléctrico (202) o de un convertidor a una temperatura comprendida entre 500ºC y 1800ºC; pretratar el gas de combustión capturado en un grupo de pretratamiento (203), a fin de obtener gas de combustión que sale de este último a una temperatura cercana a un valor comprendido entre 800 y 900ºC; dejar que el gas de combustión pretratado atraviese un intercambiador de calor (1) de acuerdo con una o más entre las reivindicaciones 1 y 16, al reducir su temperatura a un valor cercano a 200ºC, con una velocidad de temple instantáneo promedio superior o igual a 300ºC/seg. -preferentemente, igual a 350ºC/seg. y, más preferentemente, igual a 400ºC/seg.- y, así, transferir el calor sustraído de gas de combustión a un fluido de enfriamiento; recuperar el calor transferido a dicho fluido de enfriamiento para la producción de energía o de un fluido de servicio caliente.
