M'mafakitale otentha kwambiri monga zitsulo, magalasi, ndi ziwiya zadothi, ng'anjo zobwezeretsa mphamvu zimasunga mphamvu ndi kuchepetsa utsi kudzera mu ukadaulo wobwezeretsa kutentha kwa mpweya wotayidwa. Chopopera mpweya cha njira zitatu /choziziritsira mpweya wa flueValavu ya gulugufe yopumira mpweya, monga gawo lalikulu la makina obweza ng'anjo, imagwira ntchito yofunika kwambiri yosintha njira yoyendera mpweya wofewa ndi mpweya (kapena mafuta). Ndi mawonekedwe ake obweza mpweya bwino kwambiri, kuwongolera molondola, komanso kukana malo ovuta, yakhala chitsimikizo chofunikira cha uvuni zamakono zamafakitale kuti ziwongolere kugwiritsa ntchito mphamvu moyenera ndikuchepetsa kuipitsa.

Mfundo Yogwirira Ntchito: Kapangidwe ka Njira Zitatu ka Kusinthana kwa Bidirectional

Valavu yodulira damper ya Three BypassValavu ya gulugufe yopumira imagwiritsa ntchito kapangidwe ka njira zitatu kooneka ngati 'Y' yokhala ndi malo olowera awiri (A, B) ndi malo otulutsira amodzi (C), kapena malo awiri otulutsira (B, C) ndi malo amodzi otulutsira (A), zomwe zimapangitsa kuti njira yamadzimadzi isinthe mwachangu kudzera mu mbale yozungulira ya vavu. Mfundo zake zazikulu ndi izi:

1. Kuyendetsa Patsogolo: Mbale ya valavu imazungulira ku ngodya inayake, kulumikiza cholowera A ku chotulukira C pamene ikutseka cholowera B.

2. Kubwerera M'mbuyo: Mbale ya valavu imazungulira 180°, kulumikiza cholowera B ku chotulukira C pamene ikutseka cholowera A.

Mu uvuni wobwezeretsa mphamvu, ma valve amenewa nthawi zambiri amagwiritsidwa ntchito awiriawiri kuti azitha kubweza mpweya wotulutsa mpweya wa flue ndi mpweya woyaka/mafuta. Pophatikizidwa ndi ma regenerator, zimathandiza kuti kutentha kwa zinyalala kubwezeretsedwe kuchokera ku mpweya wa flue, zomwe zimawonjezera mphamvu ya kutentha kwa uvuni ndi 30%.

Ubwino waukulu wa damper core wa valve ya gulugufe: Kuchita bwino kwambiri, kukhazikika, ndi luntha 

1. Kubwerera M'mbuyo Mwachangu kwa Milliseconds kuti Ugwire Ntchito Yopitilira ya Ng'anjo

Mbale ya valavu imagwiritsa ntchito zinthu zopepuka (monga aluminiyamu, zinthu zophatikizika zolimbikitsidwa ndi ulusi wa kaboni) ndipo imagwirizanitsidwa ndi ma actuator oyenda pansi pa mpweya kapena amagetsi, zomwe zimachepetsa nthawi yobwerera m'mbuyo kufika pa ma milliseconds osakwana 500. Izi zimachotsa "mpata wosokoneza kayendedwe ka madzi" wa ma valve achikhalidwe, kuonetsetsa kutentha kokhazikika kwa uvuni ndikuchepetsa kusinthasintha kwa njira zomwe zimachitika chifukwa cha kubwerera m'mbuyo.

2. Kapangidwe ka Kusindikiza Kawiri Koyenera Kukana Kutentha Kwambiri Kowononga Media

Valavu imagwiritsa ntchito chisindikizo cholimba chachitsulo + kapangidwe ka chisindikizo chofewa chotanuka:

- Valve plate ndi malo olumikizirana ndi thupi: Okhala ndi zinthu zotentha kwambiri (monga Inconel, Hastelloy) kapena zokutira za ceramic kuti zipirire kukanda kwa mpweya wotuluka pa kutentha kopitilira 1200°C.

- Mphete zotsekera: Zopangidwa ndi rabara ya silicone, fluororubber, kapena graphite composites, zomwe zimasunga kusinthasintha kutentha kwambiri kuti zisatuluke.

Yabwino kwambiri pa malo okhala ndi mpweya woipa wokhala ndi fumbi ndi sulfure oxides.

3. Kukana Kutsika kwa Mafunde Kuti Musunge Mphamvu

Mbale ya valavu yooneka ngati disc imakhala pafupi ndi komwe madzi amalowera ikatsegulidwa kwathunthu, ndipo mphamvu yokana kuyenda kwa madzi ndi 1/3 mpaka 1/5 yokha kuposa ya ma valavu a pachipata, zomwe zimachepetsa kwambiri kugwiritsa ntchito mphamvu ya fan. Mphamvu yopulumutsa mphamvu imadziwika kwambiri pakakhala madzi ambiri (monga kupitirira 100,000 m³/h).

4. Kulamulira Mwanzeru pa Mavuto Ovuta

Valavuyi imaphatikiza masensa a malo, ma transmitter opanikizika, ndi makina a PLC/DCS kuti azitha:

①Mfundo yosinthira zinthu zomwe zingasinthidwe: Kusintha kusintha zinthu nthawi yeniyeni kutengera kutentha ndi kuthamanga kwa ng'anjo.

②Chenjezo loyambirira la cholakwika: Kuzindikira zolakwika monga kutsekeka kwa valavu kapena kulephera kwa chisindikizo ndikusinthira zokha ku backup mode.

③Kusamalira patali: Kuyang'anira momwe ma valavu alili kudzera pa nsanja za IoT kuti muchepetse ndalama zowunikira pamanja.

Kugwiritsa ntchito ma valavu a gulugufe a njira zitatu Zochitika: Njira Zosinthira Zosiyanasiyana za Uvuni wa Mafakitale 

1. Makampani Opanga Zitsulo: Ma uvuni Otenthetsera ndi Ma uvuni Otenthetsera

Mu uvuni wotenthetsera wozungulira ndi zitsulo, ma valve a gulugufe atatu amasinthira mpweya wa flue ndi mpweya kuti usamutse kutentha kwa mpweya wa flue wotentha kwambiri kupita ku ma regenerator. Mpweya wotenthetserawo umanyamula kutentha kupita ku uvuni, zomwe zimapangitsa kuti kuyaka kawiri kubwezeretsedwe komanso kuchepetsa kugwiritsa ntchito mafuta ndi 20%–40%.

2. Magalasi/Mawuni a Ceramic: Kusungunula Moyenera ndi Kusunga Mphamvu

Mu makina obwezeretsa ng'anjo yagalasi, mavavu amasinthasintha mofulumira njira zoyendera mpweya ndi mpweya, kuchepetsa mpweya wa NOx pomwe akuwonjezera mphamvu yosungunuka kwa galasi. Mu ma ceramic roller kilns, mavavu amawongolera njira yoyendera mpweya wotentha kuti agwirizane kutentha kwa ng'anjo ndikuwonjezera phindu la zinthu.

3. Zipangizo Zamankhwala ndi Zomangira: Kusamalira Zofalitsa Zovuta

Pa makina opangira mpweya wothira mankhwala okhala ndi phula ndi fumbi, zokutira za valavu zomwe sizingawonongeke komanso zomwe zimatsuka zokha zimateteza kutsekeka. Mu makina opangira magetsi otenthetsera zinyalala mu uvuni wa simenti, mavalavu amasinthasintha mpweya wozizira wotentha kwambiri ndi mpweya wozizira kuti azitha kubwezeretsanso kutentha kwa zinyalala.

4. Zipangizo Zoteteza Zachilengedwe: RTO Regenerative Thermal Oxidizers

Mu zipangizo za RTO zochizira volatile organic compound (VOCs), ma valve a gulugufe a njira zitatu amawongolera utsi ndi mpweya woyeretsedwa, kuonetsetsa kuti ma regenerator akugwiritsidwa ntchito kutentha mokwanira pamene akupirira kutentha kwakukulu nthawi yomweyo akamayaka.
