Ma Nozzles a Silicon Carbide FGD Spray
Ma Nozzle Omwe Amayamwa Mpweya Wotulutsa Fuluu (FGD)
Kuchotsa ma sulfure oxides, omwe nthawi zambiri amatchedwa SOx, kuchokera ku mpweya wotulutsa utsi pogwiritsa ntchito alkali reagent, monga slurry yonyowa ya limestone.
Mafuta akagwiritsidwa ntchito poyatsa kuti ayendetse ma boiler, uvuni, kapena zida zina, amatha kutulutsa SO2 kapena SO3 ngati gawo la mpweya wotulutsa utsi. Ma sulfure oxides amenewa amakumana mosavuta ndi zinthu zina kuti apange mankhwala owopsa monga sulfuric acid ndipo amatha kuwononga thanzi la anthu komanso chilengedwe. Chifukwa cha zotsatira zake, kuwongolera mankhwala awa mu mpweya wotulutsa mpweya ndi gawo lofunikira kwambiri pamagetsi opangira magetsi ndi ntchito zina zamafakitale.
Chifukwa cha kukokoloka kwa nthaka, kutsekeka kwa madzi, ndi kusonkhana kwa madzi, njira imodzi yodalirika kwambiri yowongolera mpweya woipawu ndi njira yotsegula mpweya wonyowa (FGD) pogwiritsa ntchito miyala yamchere, laimu wothira madzi, madzi a m'nyanja, kapena njira ina ya alkaline. Ma nozzle opopera amatha kugawa bwino komanso modalirika ma slurry awa m'malo onyamulira madzi. Mwa kupanga mapangidwe ofanana a madontho a kukula koyenera, ma nozzle awa amatha kupanga bwino malo ofunikira kuti madziwo anyamule bwino komanso kuchepetsa kulowetsedwa kwa madziwo mu mpweya wonyowa.
Zinthu Zofunika pa RBSiC Nozzles Datasheet
Kusankha Nozzle Yoyamwitsa ya FGD:
Zinthu zofunika kuziganizira:
Kutsuka ndi kukhuthala kwa media
Kukula kwa madontho ofunikira
Kukula koyenera kwa madontho ndikofunikira kuti muwonetsetse kuti madzi akumwa bwino
Zipangizo za nozzle
Popeza mpweya wotuluka m'madzi nthawi zambiri umakhala wowononga ndipo madzi otsukira nthawi zambiri amakhala ngati matope okhala ndi zinthu zolimba komanso zokwawa, kusankha zinthu zoyenera zoteteza dzimbiri ndi kukalamba ndikofunikira.
Kukana kutsekeka kwa nozzle
Popeza madzi otsukira nthawi zambiri amakhala ngati matope okhala ndi zinthu zolimba zambiri, kusankha nozzle yotetezera ku kutsekeka ndikofunikira.
Kapangidwe ka nozzle spray ndi malo ake
Pofuna kuonetsetsa kuti mpweya ukulowa bwino, ndikofunikira kuti mpweya ufike bwino popanda kulowera komanso nthawi yokwanira yogona.
Kukula ndi mtundu wa cholumikizira cha nozzle
Kuchuluka kwa madzi ofunikira oyeretsera
Kutsika kwa mphamvu komwe kulipo (∆P) kudutsa pa nozzle
∆P = kupanikizika kwa mpweya pa malo olowera mpweya - kupanikizika kwa mpweya kunja kwa mpweya
Akatswiri athu odziwa bwino ntchito angakuthandizeni kudziwa kuti ndi nozzle iti yomwe igwire ntchito malinga ndi zomwe mukufuna pa kapangidwe kanu.
Ntchito ndi Mafakitale Omwe Amagwiritsa Ntchito FGD Absorber Nozzle:
Malo opangira magetsi a malasha ndi zina zosungira mafuta
Malo oyeretsera mafuta
Malo otenthetsera zinyalala a boma
Ma uvuni a simenti
Zosungunulira zitsulo
Ma nozzle a SNBSC ndi RBSC:
Silicon Nitride Yolumikizidwa ndi Silicon Carbide (SNBSC):
Chipangizo chadothi chomwe chimalimbana bwino ndi kukokoloka ndi dzimbiri. Kuchepa kwa kuphulika (MOR) komanso kusagwira bwino ntchito kumalepheretsa chipangizocho kupanga mapangidwe osavuta okhala ndi makoma olemera. SNBSC nthawi zambiri imagwiritsidwa ntchito pa ma nozzles okhala ndi dzenje lozungulira komanso lozungulira.
Kapangidwe ka Silicon Carbide Yogwirizana (RBSC/SiSiC):
Chida chadothi chomwe chimalimbana bwino ndi kukokoloka ndi dzimbiri. Chifukwa chakuti MOR ya RBSC ndi yowirikiza ka 5-7 kuposa ya SNBSC, ingagwiritsidwe ntchito pamitundu yovuta kwambiri.
RBSC imatha kulephera kugwira ntchito chifukwa imapangidwa ndi ceramic yofooka. Ma nozzles akalephera kugwira ntchito, mwina amalephera kugwira ntchito chifukwa cha kusweka. Kusweka kumeneku kungachitike chifukwa cha njira zolakwika zoyikira, kukwera kwa mphamvu (water hammer) panthawi yoyambitsa, kuyesa kuyeretsa ma nozzles olumikizidwa kapena ntchito zina zosamalira nthawi zonse.
Shandong Zhongpeng Special Ceramics Co., Ltd ndi imodzi mwa njira zazikulu kwambiri zothetsera zinthu zatsopano za silicon carbide ceramic ku China. SiC technical ceramic: Kuuma kwa Moh ndi 9 (Kuuma kwa New Moh ndi 13), komwe kumalimbana bwino ndi kukokoloka ndi dzimbiri, kukana bwino kwambiri - kukana komanso kukana okosijeni. Moyo wa ntchito wa SiC ndi wautali nthawi 4 mpaka 5 kuposa 92% alumina. MOR ya RBSiC ndi nthawi 5 mpaka 7 kuposa ya SNBSC, ingagwiritsidwe ntchito pazinthu zovuta kwambiri. Njira yowerengera mawu ndi yachangu, kutumiza kumakhala monga momwe kunalonjezera ndipo khalidwe lake ndi lapamwamba kwambiri. Nthawi zonse timapitilizabe kutsutsa zolinga zathu ndikubwezera mitima yathu kwa anthu.
