Title
(EN) FOULING DETECTION SETUP AND METHOD TO DETECT FOULING
(FR) INSTALLATION DE DÉTECTION D'ENCRASSEMENT ET PROCÉDÉ DE DÉTECTION D'ENCRASSEMENT
Abstract
(EN)
The invention refers to a fouling detection setup (1 ) and method for determining the amount of fouling (5) of surfaces (3) of fluid (6) treating devices (2) and/or internal functional components (4) of such devices, which are exposed to said fluid and are subjected to fouling. Fouling detection setups and methods are useful for monitoring the amount of fouling of surfaces, e.g. heat-transfer surfaces and also for monitoring the cleaning procedure of such fluid treating devices and/or internal functional components of such devices. According to the invention the detection setup (1 ) comprises at least one first sensor (7), with means (9) for measuring the optical transparency T and/or electrical conductive conductivity Q of said fluid (6). The Sensor includes at least one sensitive area (8) that is located nearby and/or within said surfaces (3) and wherein said area is at least temporarily exposed to said fluid (6).
(FR)
L'invention porte sur une installation de détection d'encrassement (1) et sur un procédé de détermination de l'amplitude d'encrassement (5) de surfaces (3) de dispositifs de traitement (2) de fluide (6) et/ou d'éléments fonctionnels internes (4) de tels dispositifs exposés audit fluide et sujets à un encrassement. Les installations et les procédés de détection d'encrassement sont utiles pour la surveillance de l'amplitude d'encrassement d'une surface, par exemple de surfaces d'échange thermique et également pour la surveillance de la procédure de nettoyage de tels dispositifs de traitement de fluide et/ou des éléments fonctionnels internes de tels dispositifs. Selon l'invention, l'installation de détection (1) comprend au moins un premier capteur (7) comportant des moyens (9) de mesure de la transparence optique T et/ou de la conductivité électrique Q dudit fluide (6). Le capteur comprend au moins une zone sensible (8) localisée près desdites surfaces (3) ou à l'intérieur de celles-ci, et ladite zone étant au moins temporairement exposée audit fluide (6).
