Abstract

La presente invención se refiere a un sistema de inundación posterior para impregnadores de ósmosis inversa para instalaciones del tipo que comprende uno o más impregnadores de ósmosis inversa, estando su porción de entrada de agua de alimentación en comunicación de flúido con una línea de agua de alimentación a presión, una línea de concentrado, provista de dispositivos de restricción de flujo y la porción de salida de producto de cada impregnador es mantenida en comunicación de fluido con una línea de salida de producto, caracterizada porque comprende: una línea de agua de alimentación, provista de una válvula de control de agua de alimentación, en una condición normalmente "abierta", impulsada automáticamente a la condición "cerrada" cada vez que ocurre la terminación del flujo a alta velocidad en la línea de agua de alimentación y en la línea de concentrado; una fuente de líquido de inundación provista a un nivel superior al de los impregnadores que van a ser inundados, con una columna suficientemente alta para proveer una presión, debida a la gravedad, suficiente para inundar efectivamente los impregnadores; una línea de suministro de líquido de inundación que conecta la fuente de líquido de inundación a la línea de agua de alimentación en un punto corriente abajo de la válvula de control de agua de alimentación, y provista de una válvula de control de líquido de inundación, en una condición normalmente "cerrada", impulsada automáticamente a la condición "abierta" siempre que ocurre dicha terminación de flujo a alta velocidad, y provista de una línea de derivación conectada a la línea de concentrado, de manera que derive los dispositivos de restricción de flujo; y que está provista de una válvula de control de derivación en una condición normalmente "cerrada", impulsada automáticamente a la condición "abierta" siempre que ocurre la terminación del flujo a alta velocidad; estando dispuesta la línea de derivación para mantener dicha membrana sumergida en el líquido de inundación mientras dure la terminación del flujo a alta velocidad.The present invention relates to a post-flood system for reverse osmosis impregnators for installations of the type comprising one or more reverse osmosis impregnators, its feed water inlet portion being in fluid communication with a feed water line under pressure, a concentrate line, provided with flow restriction devices and the product outlet portion of each impregnator is maintained in fluid communication with a product outlet line, characterized in that it comprises: a feed water line, Provided with a feed water control valve, in a normally "open" condition, automatically driven to the "closed" condition each time high-speed flow termination occurs in the feed water line and in the supply line. concentrated; a source of flood liquid provided at a level higher than that of the impregnators to be flooded, with a column high enough to provide a pressure, due to gravity, sufficient to effectively flood the impregnators; a flood liquid supply line connecting the flood liquid source to the feed water line at a point downstream of the feed water control valve, and provided with a flood liquid control valve, in a normally "closed" condition, automatically driven to the "open" condition whenever such high-speed flow termination occurs, and provided with a bypass line connected to the concentrate line, bypassing the flow restriction devices flow; and that it is provided with a bypass control valve in a normally "closed" condition, automatically driven to the "open" condition whenever high-speed flow termination occurs; the bypass line being arranged to keep said membrane immersed in the flood liquid for the duration of the termination of the flow at high speed.
