Momwe mungawerengere kuchuluka kwa kusungunuka ndi zokolola za ng’anjo yosungunuka?

Ziyenera kunenedwa kuti kusungunuka mphamvu deta ya ng’anjo yamagetsi yoperekedwa ndi ambiri chowotcha kutentha wopanga mu zitsanzo kapena zaukadaulo ndi kuchuluka kwa kusungunuka. Kusungunuka kwa ng’anjo yamagetsi ndi khalidwe la ng’anjo yamagetsi palokha, limagwirizana ndi mphamvu ya ng’anjo yamagetsi ndi mtundu wa gwero la mphamvu, ndipo alibe chochita ndi machitidwe opangira ntchito. Kupanga kwa ng’anjo yamagetsi sikungokhudzana ndi kusungunuka kwa kutentha kwa ng’anjo yamagetsi yokha, komanso kumagwirizana ndi kayendedwe ka ntchito yosungunuka. Kawirikawiri, pali nthawi ina yopanda katundu wothandizira nthawi yosungunuka, monga: kudyetsa, skimming, sampuli ndi kuyesa, kuyembekezera zotsatira za mayesero (zokhudzana ndi njira zoyesera), kuyembekezera kuthira, etc. nthawi zothandizira zopanda katunduzi zimachepetsa kuyika kwa mphamvu yamagetsi, ndiko kuti, kumachepetsa kusungunuka kwa ng’anjo yamagetsi.

Kuti tifotokoze momveka bwino, timafotokozera mfundo zogwiritsira ntchito mphamvu ya ng’anjo yamagetsi K1 ndi kugwiritsa ntchito mphamvu K2.

Mphamvu yogwiritsira ntchito ng’anjo yamagetsi yamagetsi K1 imatanthawuza chiŵerengero cha mphamvu yotulutsa mphamvu yamagetsi ku mphamvu yake yovotera panthawi yonse yosungunuka, ndipo imagwirizana ndi mtundu wa magetsi. Mtengo wa K1 wa ng’anjo yapakatikati yomwe imakhala ndi silicon controlled (SCR) full-bridge parallel inverter solid power supply nthawi zambiri imakhala mozungulira 0.8. Xi’an Institute of Mechanical and Electrical Technology yawonjezera kuwongolera kwa inverter ku mtundu uwu wamagetsi (kawirikawiri mtundu uwu wamagetsi umangokhala ndi rectifier control), mtengo ukhoza kukhala pafupi ndi 0.9 kapena apo. Mtengo wa K1 wa ng’anjo yapakatikati yokhala ndi (IGBT) kapena (SCR) theka la mlatho wosinthira mphamvu yogawana magetsi olimba amatha kufika pa 1.0.

Kukula kwa mphamvu yogwiritsira ntchito mphamvu yogwiritsira ntchito mphamvu ya K2 ikugwirizana ndi zinthu monga ndondomeko ya ndondomeko ndi kayendetsedwe ka kayendetsedwe ka msonkhano wosungunula, ndi ndondomeko yokonzekera magetsi a ng’anjo yamagetsi. Mtengo wake ndi wofanana ndi chiŵerengero cha mphamvu yeniyeni yotulutsa mphamvu yamagetsi ku mphamvu yotulutsidwa panthawi yonse yogwira ntchito. Nthawi zambiri, mphamvu yogwiritsira ntchito mphamvu ya K2 imasankhidwa pakati pa 0.7 ndi 0.85. Kufupikitsa kwa nthawi yogwiritsira ntchito ng’anjo yamagetsi yopanda katundu (monga: kudyetsa, sampuli, kuyembekezera kuyezetsa, kuyembekezera kuthira, etc.), mtengo wa K2 wokulirapo. Pogwiritsa ntchito Table 4 Scheme 4 (magetsi apawiri okhala ndi ng’anjo iwiri ya ng’anjo), mtengo wa K2 ukhoza kufika pa 1.0, makamaka, ukhoza kufika kupitirira 0.9 pamene nthawi yogwira ntchito yowonjezereka ya ng’anjo yamagetsi ndi yochepa kwambiri.

Chifukwa chake, zopanga N za ng’anjo yamagetsi zitha kuwerengedwa motere:

N = P·K1·K2 / p (t/h)………………………………………………………………(1)

kumene:

P – adavotera mphamvu ya ng’anjo yamagetsi (kW)

K1 – Mphamvu yogwiritsira ntchito ng’anjo yamagetsi, nthawi zambiri imakhala pakati pa 0.8 ~ 0.95

K2 – Mphamvu yogwiritsira ntchito mphamvu, 0.7 ~ 0.85

p – Kugwiritsa ntchito ng’anjo yamagetsi yamagetsi (kWh/t)

Tengani ng’anjo yosungunuka ya 10t yapakatikati yokhala ndi 2500kW silicon controlled (SCR) full-bridge parallel inverter solid power supply yopangidwa ndi Institute of Mechanical and Electrical Engineering monga chitsanzo. The unit melting consumption p yosonyezedwa muzitsulo zamakono ndi 520 kWh / t, ndi mphamvu yogwiritsira ntchito mphamvu ya ng’anjo yamagetsi Mtengo wa K1 ukhoza kufika pa 0.9, ndipo mtengo wa ntchito yogwiritsira ntchito mphamvu K2 imatengedwa ngati 0.85. Kupanga kwa ng’anjo yamagetsi kumatha kupezeka monga:

N = P·K1·K2 / p = 2500·0.9·0.85 / 520 = 3.68 (t/h)

Ziyenera kunenedwa kuti ogwiritsa ntchito ena amasokoneza tanthauzo la kuchuluka kwa kusungunuka ndi kutulutsa, ndikuziwona ngati tanthauzo lomwelo. Sanaganizire za K1 yogwiritsira ntchito mphamvu ya ng’anjo yamagetsi ndi mphamvu yogwiritsira ntchito mphamvu ya K2. Chotsatira cha chiwerengerochi chikanakhala N = 2500/520 = 4.8 (t / h). Ng’anjo yamagetsi yosankhidwa mwanjira imeneyi silingathe kukwaniritsa zokolola zomwe zapangidwa.
