Les cendres volantes sont un type de d\u00e9chet industriel rejet\u00e9 par les centrales \u00e9lectriques au charbon. Elles ne peuvent \u00eatre raisonnablement utilis\u00e9es pour une seconde exploitation qu'apr\u00e8s un traitement appropri\u00e9. <\/p>\n\n\n\n

Parmi les \u00e9quipements de traitement se trouve l'\u00e9quipement de s\u00e9chage ; un s\u00e9cheur de cendres volantes est un \u00e9quipement sp\u00e9cialis\u00e9 pour le s\u00e9chage des minerais. Il pr\u00e9sente les avantages d'un coefficient de s\u00e9chage \u00e9lev\u00e9, d'une op\u00e9ration simple, d'un faible taux de panne, de la s\u00e9curit\u00e9 et de la protection de l'environnement, etc.<\/p>\n\n\n

Structure du s\u00e9cheur de cendres volantes<\/h2>\n\n\n\n

Le m\u00e9canisme du s\u00e9cheur de cendres volantes n'est pas simplement un s\u00e9cheur basique, mais un syst\u00e8me de s\u00e9chage. Il se compose de 3 parties : le syst\u00e8me de chauffage, le syst\u00e8me d'\u00e9change thermique et le syst\u00e8me de ventilation et d\u00e9poussi\u00e9rage. Chaque syst\u00e8me r\u00e9alise une combinaison organique et exerce efficacement son meilleur effet. L'ensemble du syst\u00e8me int\u00e8gre l'alimentation en chaleur, le s\u00e9chage et la collecte des poussi\u00e8res en un tout organique, ce qui permet au syst\u00e8me global d'offrir une efficacit\u00e9 de s\u00e9chage sup\u00e9rieure.<\/p>\n\n\n

Principe de fonctionnement du s\u00e9cheur de cendres volantes<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Dans le cylindre de s\u00e9chage, le flux d'air chaud peut \u00eatre r\u00e9parti de mani\u00e8re raisonnable sur l'ensemble du cylindre. Les cendres volantes sont introduites par l'extr\u00e9mit\u00e9 basse temp\u00e9rature du cylindre de s\u00e9chage ; apr\u00e8s s\u00e9chage, l'humidit\u00e9 est \u00e9vapor\u00e9e, puis elles sont \u00e9vacu\u00e9es par l'extr\u00e9mit\u00e9 haute temp\u00e9rature. L'humidit\u00e9 de la poudre de cendres volantes s\u00e9ch\u00e9e est de 1 % \u00e0 3 %, et la finesse de la poudre de cendres volantes (r\u00e9sidu au tamis de 80 \u03bcm) est de 15 % \u00e0 20 %.<\/p>\n\n\n

Avantages de performance du s\u00e9cheur de cendres volantes<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

1. Le s\u00e9cheur de cendres volantes utilise un \u00e9quipement de d\u00e9poussi\u00e9rage sp\u00e9cial, offrant une r\u00e9sistance \u00e0 la corrosion, aux hautes temp\u00e9ratures, \u00e0 la condensation et aux br\u00fblures de sacs, ce qui am\u00e9liore efficacement la dur\u00e9e de vie de l'\u00e9quipement de d\u00e9poussi\u00e9rage.<\/p>\n\n\n\n

2. La conception de la pression d'air et du d\u00e9bit d'air a \u00e9t\u00e9 optimis\u00e9e, garantissant efficacement l'augmentation de la production par unit\u00e9.<\/p>\n\n\n\n

3. La conception principale du s\u00e9cheur de cendres volantes est sp\u00e9ciale, avec l'ajout d'une plaque de levage centrale, ce qui prolonge le parcours du mat\u00e9riau et augmente la production de s\u00e9chage.<\/p>\n\n\n\n

4. L'augmentation du nombre de retournements des cendres volantes en cours de traitement implique l'allongement de la longueur du corps principal, permettant un s\u00e9chage complet des mat\u00e9riaux et am\u00e9liorant la qualit\u00e9 du s\u00e9chage.<\/p>\n\n\n\n

5. Le s\u00e9cheur de charbon pulv\u00e9ris\u00e9 adopte un four fluidis\u00e9 \u00e9conome en \u00e9nergie, am\u00e9liorant la capacit\u00e9 et l'efficacit\u00e9 de chauffage ; en utilisant le principe du s\u00e9chage par r\u00e9cup\u00e9ration de chaleur perdue, il poss\u00e8de une forte capacit\u00e9 d'\u00e9conomie d'\u00e9nergie et de r\u00e9duction de la consommation.<\/p>\n\n\n\n

6. Le s\u00e9cheur de cendres volantes adopte un contr\u00f4le automatique interne, une op\u00e9ration simple et stable.<\/p>\n\n\n\n

7. Le s\u00e9cheur de cendres volantes a une structure simple et une empreinte r\u00e9duite, ce qui r\u00e9duit efficacement l'investissement en g\u00e9nie civil.<\/p>\n\n\n\n

8. Le s\u00e9cheur de cendres volantes utilise une t\u00f4le d'acier alli\u00e9, offrant une r\u00e9sistance \u00e0 l'usure exceptionnelle ; et l'\u00e9quipement lui-m\u00eame peut \u00eatre facilement ajust\u00e9 selon l'indice d'humidit\u00e9 requis, r\u00e9duisant ainsi la difficult\u00e9 d'op\u00e9ration.<\/p>\n\n\n
