Abstract

Horno de oxidación para el tratamiento oxidativo de fibras con a) una carcasa (2), que a excepción de zonas de entrada y salida para las fibras es estanca al gas; b) una cámara (6) de proceso situada en el espacio interior de la carcasa (2); c) un dispositivo (13) de inyección dispuesto en la zona central de la cámara (6) de proceso, con el que puede inyectarse aire caliente en sentidos opuestos en la cámara (6) de proceso y que comprende una pluralidad de cajas (18; 118) de inyección dispuestas una sobre otra con una distancia vertical, que presentan una abertura de entrada para el aire caliente y en lados opuestos en cada caso aberturas de descarga para el aire caliente; d) en ambas zonas de extremo opuestas de la cámara (6) de proceso en cada caso un dispositivo (14, 15) de succión, que succiona aire caliente desde la cámara (6) de proceso; e) al menos un ventilador (31a, 31b), que hace circular el aire caliente a través del dispositivo (13) de inyección, la cámara (6) de proceso y los dos dispositivos (14, 15) de succión; f) al menos un dispositivo (32a, 32b) de calentamiento situado en el trayecto de flujo del aire caliente que se ha hecho circular; g) rodillos (24, 25) de guiado, que guían las fibras de manera serpenteante a través de los espacios intermedios entre cajas (18; 118) de inyección situadas una sobre otra, caracterizado porque h) están previstas dos pilas de cajas (18) de inyección dispuestas con una distancia una sobre otra, que visto en el sentido de movimiento de las fibras (20) están dispuestas con una distancia una detrás de otra; o i) las cajas (118) de inyección en una pila presentan en el lado superior y el lado inferior una pluralidad de aberturas (130) de descarga adicionales para aire caliente, que están dispuestas a lo largo de una línea central de las cajas (118) de inyección.Oxidation furnace for the oxidative treatment of fibers with a) a casing (2), which, except for the inlet and outlet areas for the fibers, is gas-tight; b) a process chamber (6) located in the interior space of the casing (2); c) an injection device (13) arranged in the central area of the process chamber (6), with which hot air can be injected in opposite directions into the process chamber (6) and comprising a plurality of boxes (18 ; 118) injection nozzles arranged one above the other with a vertical distance, having an inlet opening for hot air and on opposite sides in each case discharge openings for hot air; d) in both opposite end regions of the process chamber (6) in each case a suction device (14, 15), which sucks hot air from the process chamber (6); e) at least one fan (31a, 31b), which circulates the hot air through the injection device (13), the process chamber (6) and the two suction devices (14, 15); f) at least one heating device (32a, 32b) located in the flow path of the hot air that has been circulated; g) guide rollers (24, 25), which guide the fibers in a meandering manner through the intermediate spaces between injection boxes (18; 118) located one above the other, characterized in that h) two stacks of boxes (18 injection) arranged with a distance one above the other, which seen in the direction of movement of the fibers (20) are arranged with a distance one behind the other; or i) the injection boxes (118) in a stack have on the upper side and the lower side a plurality of additional discharge openings (130) for hot air, which are arranged along a center line of the boxes (118 ) of injection.
