Contexte de l’\u00e9tude de cas de la station d’\u00e9puration<\/h2>\n

Une station d’\u00e9puration (ci-apr\u00e8s STEP) a r\u00e9cemment contact\u00e9 SACOME pour trouver une solution \u00e0 un probl\u00e8me de colmatage d’un \u00e9changeur de chaleur \u00e0 spirale existant. Cet \u00e9changeur de chaleur \u00e9tait destin\u00e9 \u00e0 chauffer les boues en vue de leur digestion ana\u00e9robie ult\u00e9rieure dans un digesteur pour la production de biogaz. L’\u00e9changeur de chaleur existant se bouchait trop souvent, obligeant notre client \u00e0 des arr\u00eats de production fr\u00e9quents et co\u00fbteux pour effectuer des travaux de nettoyage.<\/p>\n

Apr\u00e8s ce premier contact, nos techniciens se sont rendus \u00e0 plusieurs reprises dans les installations de la STEP pour analyser de pr\u00e8s le probl\u00e8me de notre client afin de pouvoir lui proposer une solution adapt\u00e9e \u00e0 ses besoins.<\/p>\n

La solution propos\u00e9e : les \u00e9changeurs de chaleur tubulaires<\/h2>\n

Il existe diff\u00e9rentes g\u00e9om\u00e9tries d’\u00e9changeurs de chaleur sur le march\u00e9 : \u00e0 plaques, en spirale ou tubulaires, pour ne citer que les plus repr\u00e9sentatives. Le fonctionnement des \u00e9changeurs de chaleur \u00e0 plaques n’est pas adapt\u00e9 au traitement des boues, c’est pourquoi les g\u00e9om\u00e9tries en spirale et tubulaire ont traditionnellement pr\u00e9valu dans les complexes de STEP.<\/p>\n

Bien que les \u00e9changeurs en spirale soient tr\u00e8s r\u00e9pandus dans ce secteur, la recherche d’une meilleure performance du digesteur ana\u00e9robie conduit \u00e0 traiter des boues de plus en plus complexes : plus denses, plus visqueuses et avec une teneur plus \u00e9lev\u00e9e en solides et en fibres. Dans ces conditions, un \u00e9changeur \u00e0 spirale peut rencontrer des probl\u00e8mes de colmatage des canaux de passage internes, ce qui n\u00e9cessite des op\u00e9rations de nettoyage fr\u00e9quentes, entra\u00eenant des arr\u00eats de production.<\/p>\n

La solution propos\u00e9e par SACOME repose donc sur l’installation d’un \u00e9changeur tubulaire de notre Ligne Industrielle, sp\u00e9cialement con\u00e7u pour le traitement des boues et des boues des stations d’\u00e9puration.<\/p>\n

\n

Nos \u00e9changeurs de chaleur tubulaires sont la solution \u00e0 ce probl\u00e8me car ils ont une section transversale beaucoup plus grande que les \u00e9quipements en spirale, ce qui \u00e9vite le risque de blocage et permet un fonctionnement continu, minimisant ainsi le nombre d’arr\u00eats de maintenance n\u00e9cessaires.<\/p>\n<\/blockquote>\n

Cette STEP produit une grande quantit\u00e9 de d\u00e9chets organiques. Afin de r\u00e9duire le volume de ces d\u00e9chets et de limiter la pollution, ces d\u00e9chets ou boues sont envoy\u00e9s dans un dispositif appel\u00e9 digesteur ana\u00e9robie. Dans cet \u00e9quipement, la d\u00e9gradation biochimique des boues a lieu gr\u00e2ce \u00e0 l’action bact\u00e9riologique dans un environnement \u00e0 temp\u00e9rature contr\u00f4l\u00e9e et en l’absence d’oxyg\u00e8ne, et leur transformation en biogaz. La digestion ana\u00e9robie de ces boues permet non seulement la r\u00e9duction des d\u00e9chets, mais aussi leur valorisation \u00e9nerg\u00e9tique, le biogaz \u00e9tant un gaz \u00e0 haut pouvoir calorifique, du fait de sa composition riche en m\u00e9thane, comme le montre le diagramme \u00e0 barres.<\/p>\n

Ce biogaz est stock\u00e9 dans un gazom\u00e8tre o\u00f9, apr\u00e8s avoir subi un traitement visant \u00e0 \u00e9liminer les compos\u00e9s polluants ou corrosifs, il peut \u00eatre utilis\u00e9 comme carburant dans des moteurs sp\u00e9cialement pr\u00e9par\u00e9s, qui peuvent \u00e0 leur tour entra\u00eener un alternateur et produire de l’\u00e9lectricit\u00e9 qui peut \u00eatre inject\u00e9e dans le r\u00e9seau \u00e9lectrique.<\/p>\n

Chauffage des boues de pr\u00e9-digesteur : un processus critique<\/h2>\n

 <\/p>\n

La temp\u00e9rature des boues \u00e0 l’entr\u00e9e du digesteur ana\u00e9robie est un param\u00e8tre cl\u00e9, car elle influence de mani\u00e8re significative le temps de r\u00e9tention requis pour le processus de digestion n\u00e9cessaire aux bact\u00e9ries pour dig\u00e9rer la mati\u00e8re. Il a \u00e9t\u00e9 d\u00e9montr\u00e9 qu’\u00e0 30\u00b0C, environ 10 jours sont n\u00e9cessaires pour cette digestion m\u00e9sophile, alors qu’\u00e0 20\u00b0C, environ 25 jours sont n\u00e9cessaires. Compte tenu de ces r\u00e9sultats, il est \u00e9vident qu’il est tr\u00e8s important de contr\u00f4ler cette temp\u00e9rature dans des marges \u00e9troites afin de pouvoir stabiliser les boues qui vont dans le digesteur.<\/p>\n

 <\/p>\n

Les boues sont chauff\u00e9es dans un \u00e9changeur de chaleur, dont le bon fonctionnement est essentiel \u00e0 une digestion efficace.<\/p><\/blockquote>\n

Sp\u00e9cifications des produits dans la station d’\u00e9puration<\/h2>\n

 <\/p>\n

En raison de la variabilit\u00e9 de la teneur en mati\u00e8res solides des boues d’une STEP \u00e0 l’autre, les propri\u00e9t\u00e9s thermiques des boues, en particulier la viscosit\u00e9, peuvent changer consid\u00e9rablement.<\/p>\n

Outre la viscosit\u00e9, les propri\u00e9t\u00e9s thermiques telles que la densit\u00e9, la chaleur sp\u00e9cifique et la conductivit\u00e9 thermique sont des param\u00e8tres qui peuvent affecter de mani\u00e8re significative la conception thermique de l’\u00e9changeur de chaleur. Dans ce projet, les propri\u00e9t\u00e9s thermiques ont \u00e9t\u00e9 convenues avec le client en tenant compte de nos suggestions selon notre base de donn\u00e9es de produits, dans laquelle nous avons les propri\u00e9t\u00e9s des boues avec diff\u00e9rentes valeurs d’extrait sec.<\/p>\n

Pour ce processus, en raison du pourcentage \u00e9lev\u00e9 de solides dans les boues, notre d\u00e9partement technique a propos\u00e9 notre mod\u00e8le d’\u00e9changeur de chaleur tubulaire I-TF20-I, une solution id\u00e9ale pour \u00e9viter le colmatage des tubes en raison de sa g\u00e9om\u00e9trie (\u00e9changeur de chaleur tube dans tube).<\/p>\n

Notre \u00e9changeur de chaleur tubulaire I-TF20-I se compose de deux tubes concentriques dans lesquels l’eau utilis\u00e9e comme fluide de chauffage circule dans l’espace annulaire, tandis que la boue ou les boues circulent dans le tube int\u00e9rieur. Contrairement \u00e0 l’\u00e9changeur de chaleur multitubulaire traditionnel, qui consiste en un faisceau tubulaire de tubes de plus petit diam\u00e8tre, ce mod\u00e8le poss\u00e8de un seul canal d’\u00e9coulement.<\/p>\n
