Abstract

El invento consiste en un sistema de medición directa e indirecta del proceso de intercambio de calor entre dos fluidos, uno de los cuales provoca el crecimiento de película biológica en el interior de los tubos de un haz tubular (biofouling) debido a que ese fluido contiene microorganismos. El sistema valora en continuo el crecimiento del biofouling adherido en la superficie interna del tubo de un intercambiador y consta de dos partes diferenciales: la que supervisa el biofouling mediante un sistema directo (muestra de película biológica), y la que controla este fenómeno no deseable de forma indirecta, por medio de la medida del factor de fricción y de la resistencia a la transferencia de calor.The invention consists of a direct and indirect measurement system of the heat exchange process between two fluids, one of which causes the growth of a biological film inside the tubes of a tubular bundle (biofouling) because that fluid contains microorganisms. The system continuously assesses the growth of biofouling adhered to the internal surface of an exchanger tube and consists of two different parts: the one that monitors biofouling through a direct system (biological film sample), and the one that controls this undesirable phenomenon. indirectly, by measuring the friction factor and the resistance to heat transfer.
