Deaerator - ndichiyani? Mitundu chipangizo, mfundo opaleshoni

Boilers zambiri zopangidwa ndi zitsulo. Kudutsa madzi therethrough mu dongosolo ali mpweya ndi mpweya. Onse zinthu izi ndi pa nyumba zitsulo za kukatentha kungasokoneze kwambiri. Zonse kukhudzana ndi mpweya zakhala n'kogwiritsa rusting ake. deaerator - kuti kuthetsa vutoli ndi kutalikitsa moyo wa zida, unsembe apadera m'gulu ikukhudzana kukatentha chiwembu. Ndi chiyani icho? Pa izi ndi kudzayankhula kenako m'nkhani ino.

tanthauzo

Deaerator otchedwa zipangizo zina zapadera cholinga kuchotsa mpweya ku kachitidwe coolant Kutentha ndi Kutentha boti lotsiriza. Choncho, kuwonjezera pa ntchito yoyeretsa, mtundu wa zipangizo ntchito monga kutentha. The khwekhwe chomwecho angagwiritsidwe ntchito deaeration ndi Kutentha mankhwala monga michere ndi odzipangitsa-madzi.

kapangidwe

Kuphweka wachibale wa kapangidwe - ndicho chimene chimasiyanitsa de A-aerator. Kodi ife akupezeka. Tsopano tiyeni tiwone momwe zida zoti. Bwaloli kukatentha deaerator thanki (BDA) ndi wokwera adalira ndi ndime ofukula (KDA) wokwera pa zogwiriziza. Mfundo zina za mtundu uwu wa zida ndi dongosolo hayidiroliki amateteza izo kuchokera overpressure. mzati ndi welded ku thanki popanda flange - mwachindunji.

Pa thankiyo yopingasa deaerator wokwera polowera ndi kubwereketsa kulumikiza sing'anga chakudya ndi kumaliseche mizere. Pansi-wokwera limalephera. mbali inanso ya kamangidwe cholinga cha mndandanda wa degassed thanki madzi yosonkhanitsa. Malowa ali pamtunda pansi pansi BDA.

dongosolo hayidiroliki zida monga deaerator, ndi chithunzi cha chomwe chili m'munsimu, amangoona zigwirizana maloko awiri hayidiroliki. Mmodzi amateteza chipangizo kuchokera savutitsa kwambiri, ndipo chachiwiri - kuyambira oopsa. Komanso pomanga dongosolo hayidiroliki chikuphatikizapo deaerator thanki kukula. Asanduke nthunzi imayambira deaerator ku coolant wapadera kukhala yamphamvu yopingasa.

ndime kapangidwe

mzati ndi chipolopolo cylindrical ndi pansi pa mawonekedwe elliptical. Monga m'galimoto, pa iwo pali kugwirizana kwa okwanira ndi kuchotsa a sing'anga. Mkati mzati ndi mbale wapadera ndi mabowo mwa madzi akudutsa. Izi amalola zayamba kuonjezera dera kukhudzana sing'anga ndi nthunzi, motero kuti kutenthetsa ndi liwiro pazipita.

mitundu ya zida

Mu boilers masiku ano anaika deaerator madzi:

• zingalowe;

• aspirated.

Mu mtundu woyamba deaerators kuchotsa mpweya yopangidwa kuchokera ku madzi vacuo. Pa ntchito yomanga maofesi amenewa zina m'gulu madzi-ndege kapena nthunzi ejector. Mtundu yotsirizira ya mfundo ntchito zambiri mu pakati kapena otsika mphamvu kukatentha kachitidwe. M'malo ejectors mapampu wapadera angagwiritsidwe ntchito kulenga kuyamwa. Ena kusowa kwa zipangizo monga zingalowe degasser, ndi kuti ayenera kuchotsedwa ndi mphamvu, pamene iye amapita kunja kwa mlengalenga mwachibadwa - opanikizika.

Kuwonjezera pa mitundu iwiri takambirana deaerator, kukatentha akhoza kuikidwa chipangizo kwambiri. Iwo ntchito pa 0.6-0.8 MPa. Nthawi zina kutentha kukatentha dera ilinso ndi zida otsika mavuto.

Kuchuluka kwa ntchito

Ali de A-aerator angagwiritsidwe ntchito? Kodi izo, tsopano inu mukudziwa. Popeza chipangizo lakonzedwa kuti degassing sing'anga ntchito, icho ntchito kwenikweni kumene Kutentha zida zopangidwa ndi zitsulo.

Nthawi zambiri, de-aerators ntchito magetsi ndi madzi otentha machitidwe. Kukatentha zipinda ndi boilers zambiri zili ndi zoikamo zingalowe-choyimira. Komanso bleeders angagwiritsidwe ntchito njira zimenezi mumlengalenga. Choyenera otsika ndi kuthamanga chagwiritsidwa pa machitidwe kwambiri zikomo zikugwira ntchito kwa kukatentha ndi nthunzi. The zosiyanasiyana choyamba (pa 0.025-0.2 MPa) yakwera mu injini osati amphamvu kwambiri, anaikira ochepa ogula. Choyenera kukwezeka kuthamanga ntchito mu madera matenthedwe ndi boilers, kudyetsa chiwiya nthunzi.

Poppet degasser: opareshoni

Chiwembu kuyeretsedwa mpweya kuzindikira mu awiri gawo deaerators: Kuphulika (mu mzati) ndi kuwira (m'galimoto). Komanso, dongosolo ndi kugwiritsa adalowetsedwa kuonekeratu chipangizo. Madzi kudyetsedwa kwa ndime kumene nthunzi ya lichitidwa kukonzedwa. Komanso, wasefukira pansi mu thanki, iwo anakhalabe m'menemo ndi akatulutsidwa kumbuyo mu dongosolo. Nthunzi poyamba zimalowa BDA. Pambuyo mosonyeza buku mkati chimatilowetsa ndime ya. Kudutsa una wa thireyi kuwira, nthunzi likamatenthetsa madzi kuti machulukitsidwe kutentha.

Zikutchinga amachotsa madzi onse kuchokera ku mipweya lapansi. Pa nthawi yomweyo pali nthunzi condensation. mtembo wake wothira mafuta woterowu kwa sing'anga ndi amachoka mu ozizira pa. The condensate kwa nthunzi ndi amachoka mu thanki ngalande. Pa sedimentation ndi madzi mu thanki yotsalira thovu yaing'ono mpweya kutuluka izo. Madzi kuchotsedwa kwa thanki likhale. Nthawi zina chidebe yopingasa ntchito kokha lothetsera. Mu makhazikitsidwe zimenezi, masitepe awiri degassing anayikidwa mu ndime ya.

Deaeration zodzoladzola madzi

ndi Kutentha dongosolo madzi amazungulira mosalekeza. Koma kuchuluka kwa nthawi zonse, chifukwa mu kuchucha, komabe pang'onopang'ono amachepetsa. Choncho, kudzipangitsa mmwamba madzi aziwapatsa dongosolo magetsi. Monga waukulu, izo ayenera kukumana ndi ndondomeko ya de A-aeration. Poyamba, madzi amalowa chotenthetsera, ndipo kukufika pa Zosefera wa mankhwala kuyeretsedwa. Komanso, monga thanzi, Lifikira deaerator nsanja. Atamasulidwa madzi mpweya ukufika ndi mphamvu mpope. Last amaitsogolera mu zakudya zobwezedwa kapena thanki yosungirako.

mankhwala deaeration

Choncho yankho la funso zimene deaerator kukatentha ndi yosavuta. zida izi n'cholinga madzi otentha ndi nthunzi otentha kuchotsa oxygen. Komabe, nthawi zina mpweya kuchokera coolant zomera choterocho si kwathunthu zidzachotsedwa. Pankhaniyi, kukadziyeretsa zina madzi kukatentha akhoza kuwonjezeredwa yosiyanasiyana reagents lakonzedwa kuti amange oxygen. Izi zikhoza kukhala, mwachitsanzo, ndi sodium sulfite. Pankhaniyi, kwa Mkhalidwe madzi deaeration amafuna Kutentha kwake. Apo ayi, mankhwala anachita adzakhala pang'onopang'ono kwambiri. Ndi imathandizira mpweya kumanga ndondomeko angagwiritsidwe ntchito mitundu yosiyanasiyana ya catalysts. Nthawi zina madzi ndi deaerated ndi kudutsa ndi PAD wa zodulidwa ochiritsira zitsulo. Otsiriza Pankhaniyi akuthamangira oxidized.

ogwiritsa Features

deaerator chipangizo si wovuta. Komabe, unsembe wake ziyenera kuperekedwa ndi mwambo mosamala umisiri onse chakudyacho. Pamene khazikitsa zida amenewa motsogozedwa Choyamba Ufumuyo ndi zojambula Mlengi ndi ntchito kukatentha. Asanayambe unsembe, onani unsembe ndipo anapanga ake kukonzanso kulowa. ziwonongeke wapezeka zidzachotsedwa. Ndipotu iye unsembe ndondomeko ikukhudza zotsatirazi:

• thanki wokwera pa tsinde la;

• welded thereto chako spout;

• mmunsi mwa ndime ya kudulidwa pa m'mimba mwake kunja;

• ndi ndime wokwera pa thanki (Pankhaniyi atathana mkati mbale ayenera pabwino horizontally);

• mzati ndi welded kuti thanki;

• wokwera nthunzi kuzizira ndi madzi msampha;

• malinga ndi zojambula ndi kulumikiza zodutsa;

• anapereka potseka ndi malamulo mavavu ;

• unachitikira hayidiroliki mayeso zida.

kupopera unsembe

Kamangidwe pamwamba amatchedwa Belleville. Palinso utsi bleeders. Zipangizo za mtundu uwu ntchito zochepa komanso yopingasa yosungirako thanki yaikulu mphamvu. Pakalibe mizati - ndi chimene chimasiyanitsa ndi degasser. Mfundo za ntchito komanso ndi zosiyana pang'ono. nthunzi The umaperekedwa zomera ngati m'munsi - kuchokera thanki imeneyi zisa yopingasa. Chidebe yokha lagawidwa woyendera nthambi preheating ndi deaeration. Kukatentha chakudya madzi. chipinda choyamba lili pamwamba pa nebulizer lapansi. Apa, ndi mkangano kuti mfundo kuwira ndi amalowa deaeration zone pamene nthunzi mpweya kuchotsedwa therefrom.

Kotero, ndizo zonse zimene tinganene wa chipangizo monga deaerator a. Kodi izo, ife ndikuyembekeza inu mukumvetsa, chifukwa tachita ndithu yankho mwatsatanetsatane funso limeneli. Choncho kuitana khwekhwe, kupereka ntchito yopitirira ya boilers madzi ndi nthunzi yotentha. Kusankha mitundu ndi njira unsembe zida ikuchitika malinga ndi specifications ya magetsi zipangizo ndi ntchito kukatentha.
