Precise Control Logic and Energy Efficiency Optimization of Fan and Spray Systems mu Closed-Circuit Cooling Towers
M'machitidwe ozizirira a mafakitale, kuwongolera kwa mafani ndi makina opopera omwe ali otsekedwa-nsanja zoziziritsira zozungulira zitha kutchedwa "intelligent core". Sichida chongoyamba chabe-chiyimitse, koma chosinthika mozungulira kutentha kwa madzi otuluka, chomwe chimayenera kupeza njira yabwino kwambiri yothanirana ndi kuzizira, kugwiritsa ntchito mphamvu ndi kugwiritsa ntchito madzi. Cholinga chake chachikulu ndikutengera kutentha kwa potuluka madzimadzi monga muyezo, ndikusintha mwanzeru kuchuluka kwa kutentha koyenera komanso kusinthana kwa kutentha kobisika ndi zenizeni{4}}zowunika nthawi ya zinthu zachilengedwe (monga kunyowa-kutentha kwa babu, kuuma-kutentha kwa babu, liwiro la mphepo) ndi kuchuluka kwa makina (cholinga cholowera ndi kutsika kwamadzimadzi), kupititsa patsogolo kutentha kwamadzi ndi kutulutsa kwazomwe zimayendera mtengo wogwiritsa ntchito mphamvu".

Malinga ndi mfundo za kusintha kwa kutentha, kuziziritsa-nsanja zoziziritsa zotsekeka ndi kaphatikizidwe ka kutentha koyenera komanso kusinthana kwa kutentha komwe kulibe.
The njira madzimadzi amazungulira mu koyilo chatsekedwa, ndi kutentha anasamutsidwa kwa kunja mwa koyilo khoma; mgwirizano pakati pa makina opopera ndi fani ndikusintha gawo la njira ziwiri zosinthira kutentha posintha kutentha kunja kwa koyilo.
Pamene kunyowa-kutentha kwa babu kwatsika (monga usiku, m'nyengo yachisanu kapena masiku amvula) ndipo kuziziritsa kuli pakatikati pa kuwala, makina owongolera adzapereka patsogolo kuyambitsazotsika-zogwiritsa ntchito mphamvu- pakadali pano, palibe chifukwa choyatsa fani, kungoyambitsa mpope wopopera. Madzi ochepa opopera amawapopera mofanana pamwamba pa koyilo kuti apange filimu yamadzi yopyapyala komanso yofanana.
Pambuyo pa filimu yamadzi ikukhudzana ndi mpweya, kutuluka kwachilengedwe kumachitika, ndipo kutentha kwakukulu mu koyilo kumachotsedwa kupyolera mu kusinthana kwa kutentha kosasintha. Kuphatikizika kwa "kuzizira kwa evaporative + mpweya wabwino wachilengedwe" kumangogwiritsa ntchito mphamvu ya mpope wopopera (nthawi zambiri 1/5 mpaka 1/3 ya mphamvu yakufanizira), zomwe zimafanana ndi kuzindikira "kuzizira kwaulere" ndikuchepetsa kwambiri mtengo wogwirira ntchito panthawi yopepuka.
Panthawi imodzimodziyo, pofuna kupewa kutayika kwa madzi chifukwa cha filimu yamadzi oundana kwambiri, makinawa adzawona nthawi-kuyang'anira kuchuluka kwa madzi opopera kudzera pa sensa yothamanga ndikuwongolera "kungophimba koyilo popanda kudontha", kuchepetsa kutaya kwa madzi.

Zinthu zachilengedwe zikafika poipa (monga kutentha kwambiri m’chilimwe, kowuma ndi kotentha) kapena kuchuluka kwa ntchito kumachulukira (monga kudzaza-kuchulukira kwa zida zopangira zinthu komanso kutentha kolowera kwamadzi amadzimadzi), mafunde achilengedwe amadzi opopera okha sangathenso kukwaniritsa zofunika kuzizira.
Panthawiyi, makina owongolera adzayamba njira yowonjezera yowonjezera - poyamba pang'onopang'ono kuwonjezera liwiro la mpope wopopera kuti muwonjezere kuchuluka kwa madzi opopera. Ngati kutentha kotuluka kukadali kokwera kuposa mtengo wokhazikitsidwa, fan imayambika motsimikiza. Kulowererapo kwa faniyo kumatha kutchedwa "kusintha kosintha kosintha" kwa mphamvu yoziziritsa: kudzera mu kukakamiza kokakamiza, kumayambitsa mpweya wambiri wozungulira munsanja, womwe umadutsa mwachangu pamwamba pa koyilo yophimbidwa ndi filimu yamadzi.
Kuwonjezeka kwa kuthamanga kwa mpweya sikungowonjezera kuchuluka kwa evaporation ya filimu yamadzi (kutentha kobisika kwa kutentha kumawonjezeka ndi 3-5 nthawi) komanso kumawonjezera kusiyana kwa kutentha pakati pa mpweya ndi khoma la coil (mwachangu kutentha kutentha kumawonjezeka ndi 1-2 nthawi). Pansi pa zotsatira zapawiri, mphamvu yowononga kutentha kwa dongosolo imawonjezeka ndi dongosolo la kukula.
Panthawiyi, fani ndi mpope wopopera zimalowa m'malo ogwirira ntchito. Komabe, kuchenjera kwa dongosolo lamakono lamakono lagona chifukwa sichilola kuti onse azigwira ntchito nthawi zonse, koma amazindikira "kusintha kosasunthika" kudzera muukadaulo wosinthika pafupipafupi. Kutengera chitsanzo cha fani, makina owongolera adzakhala enieni-nthawi yosintha liwiro la fani kudzera pa chosinthira pafupipafupi malinga ndi kupatuka pakati pa kutentha komweku komwe kumatuluka ndi mtengo wake: ngati kutentha kotuluka kumakhala kokwera pang'ono kuposa mtengo wokhazikitsidwa, faniyo imagwira ntchito pa liwiro lotsika la 30% -50%; ngati kupatuka kukuwonjezeka, liwiro lidzawonjezeka pang'onopang'ono mpaka kudzaza.
Mphamvu yopulumutsa ya njira yosinthirayi ndi yofunika kwambiri - popeza mphamvu yogwiritsira ntchito fani imayenderana ndi kiyibodi ya liwiro lake, liwiro likatsika kuchokera pa 100% kufika pa 70%, kugwiritsa ntchito mphamvu kumatha kuchepetsedwa ndi pafupifupi 65%, zomwe zimachepetsa kwambiri kuwonongeka kwa mphamvu pansi pa katundu wochepa.
Ulamuliro woyengedwa wa makina opopera ndi osasiyanitsidwanso ndi ukadaulo wosinthira pafupipafupi ndi-njira zambiri zophatikizira pampu. Pansanja zazikulu-zotsekedwa{3}}zozungulira, 2-mapampu atatu opopera amakhala ndi zida. Dongosolo lowongolera lidzatengera njira yapawiri ya "kusintha kwa nambala + kusintha kwa liwiro" molingana ndi kusintha kwa katundu: pampu imodzi yokha imayamba ndikugwiritsidwa ntchito pa liwiro lotsika pansi pa katundu wochepa; mpope umodzi wodzaza-wothamanga kwambiri kapena mapampu awiri otsika kwambiri amayambika ndi katundu wapakati; mapampu onse amayambika ndikugwiritsidwa ntchito pa liwiro lathunthu pokhapokha atanyamula katundu wambiri.
Kusintha kophatikizana kumeneku sikumangopewa vuto la kugwiritsa ntchito mphamvu kwa "hatchi yayikulu yokoka ngolo yaying'ono" pampopu imodzi yayikulu komanso kumapangitsa kuti makinawo azikhala odalirika pogwiritsa ntchito-pampu redundancy yambiri. Panthawi imodzimodziyo, machitidwe ena apamwamba adzakhazikitsanso valavu yolambalala mu pipeline.Pamene chinyezi chozungulira chimakhala chokwera kwambiri (monga munyengo yamvula ya maula) ndi kuchepa kwa evaporation kwa filimu yamadzi kumachepa, valavu yodutsa idzatsegulidwa yokha, kuwongolera mbali ya madzi opopera kuti abwerere ku thanki yamadzi kuchepetsa voliyumu yolakwika ya kutsitsi.Izi sizimangochepetsa kugwiritsa ntchito mphamvu pa mpope wamadzi komanso zimalepheretsa kupangika kwa sikelo pamwamba pa koyilo ndi madzi ochulukirapo (kuchuluka kumawonjezera kukana kwamafuta ndikuchepetsa kuzizira ndi 10% -20%).

Kuphatikiza pa njira yosinthira pansi pa katundu wamba, dongosolo lolamulira liyeneranso kuthana ndi zovuta zogwirira ntchito komanso zochitika zolakwika kuti zitsimikizire kukhazikika kwa ntchito. Mwachitsanzo, pamene kutentha kozungulira kumatsika kwambiri (monga kutentha pansi pa madigiri 0 usiku m'nyengo yozizira), pofuna kupewa kuwonongeka kwa zipangizo chifukwa cha kuzizira kwa filimu yamadzi kunja kwa koyilo, makina olamulira amasiya kupopera kupopera, kuyambitsa fani ndi kuyatsa "anti{2}}chida chozizira chozizira" nthawi yomweyo. Kupyolera mu kutuluka kwa mpweya wokakamizidwa ndi kutentha kwapafupi, kutentha kwa pamwamba kwa koyilo kumasungidwa pamwamba pa 5 digiri; ngati zimakupiza kulephera (monga mochulukira galimoto, tsamba kupanikizana), dongosolo yomweyo kutumiza Alamu chizindikiro, kuonjezera kutsitsi voliyumu madzi pa nthawi yomweyo, ndi kutsegula "mwadzidzidzi kulambalala payipi" kuyambitsa mbali ya ndondomeko madzimadzi mu standby kuzirala dera kupewa kwambiri ndondomeko kutentha. Kuphatikiza apo, dongosololi liziwonanso nthawi-kuyang'anira kuchuluka kwa madzi amadzi opopera (monga madulidwe, pH mtengo), ndikuyambitsanso "chida chotulutsa zonyansa komanso chida chowonjezera madzi" madziwo akatsika kuti awonetsetse kuti filimu yamadzi imatuluka nthunzi komanso moyo wautumiki wa zida.

Potengera{{0}mapindu ogwirira ntchito kwanthawi yayitali, kuwongolera bwino kwa mafani ndi makina opopera omwe ali otsekedwa{1}}kusanja zozizirirako sikungachepetse kugwiritsa ntchito mphamvu ndi kugwiritsa ntchito madzi komanso kukulitsa moyo wautumiki wa zida ndi kuchepetsa ndalama zokonzera. Malinga ndi ziwerengero za data zamakampani, poyerekeza ndi momwe zimakhalira nthawi zonse "zokhazikika-zoyambira mwachangu-imitsani", makina otenthetsera ndi kupopera omwe ali ndi mphamvu zosinthira mphamvu amatha kuchepetsa kugwiritsa ntchito mphamvu pachaka ndi 30%-40% komanso kugwiritsa ntchito madzi ndi 25%-35%. Nthawi yomweyo, kuyeretsa kwa koyilo kumakulitsidwa ndi 2-3, ndipo kulephera kwa zida kumachepetsedwa ndi 50%. Njira imeneyi ya "kupulumutsa mphamvu{16}}kupulumutsa mphamvu, kupulumutsa madzi ndi kuchepetsa kumwa" sikumangokwaniritsa zofunikira zamakampani amakono a "green and low carbon" komanso kumabweretsa phindu lalikulu pazachuma m'mabizinesi, kukhala imodzi mwa njira zofunika kwambiri zokozera makina oziziritsa ku mafakitale.
