Zowopsa za Hydrogen Leakage of Diesel Generators and Maintenance Measures

Masiku ano, Dingbo Power, wopanga ma jenereta a dizilo, adadziwitsa ogwiritsa ntchito kuopsa kwa kutayikira kwa hydrogen. ma jenereta a dizilo ndi njira zina zosamalira.

1. Kuopsa kwa kutayikira kwa haidrojeni kuchokera ku majenereta a dizilo.

① Mtengo wovotera wa hydrogen pressure sungakhale wotsimikizika, womwe ungakhudze kutulutsa kwa jenereta.

② Kugwiritsa ntchito kwambiri haidrojeni kumapangitsa kupanga haidrojeni pafupipafupi komanso kukwera mtengo.

③Dongosolo la jenereta limatha kugwira moto kapena kuphulika, kuwononga.

2. Momwe mungapezere kutayikira kwa hydrogen kwa seti ya jenereta ya dizilo.

①Yang'anani zomwe zatsikira yuniti ikatha.Nthawi zambiri, kuyesa kulimba kwa mpweya kwa jenereta kumachitika pambuyo poti hydrogen ilowa m'malo mwa mpweya.

②Yang'anani kutayikira kwa jenereta mukugwira ntchito, ndipo gwiritsani ntchito choyesa cha hydrogen kuti mupeze malo otayikira wa hydrogen.Ngati hydrogen yazindikirika kumbali ya utsi wa madzi ozizira a hydrogen ozizira, ziyenera kudziwika kuti pali kutayikira mu ozizira;ngati mita ya nayitrogeni yomwe ili pamwamba pa madzi ozizira okhazikika imayenda, ziyenera kudziwika kuti chitoliro chamadzi ozizira cha stator chikutha.

③Ikani chida chowunikira mosalekeza pa intaneti pakutayikira kwa haidrojeni.Pambuyo kupeza malo kutayikira wa hydrogen, ngati jenereta mapeto chivundikiro kapena malo olowa, akhoza losindikizidwa ndi sealant;ngati choziziritsa cha hydrogen chili ndi kutayikira, chimatha kudzipatula payekhapayekha.Kwa jenereta ya 300MW, nthawi zambiri pamakhala magulu anayi ndi okwana asanu ndi atatu Kwa ozizira, kudzipatula kumodzi kumakhala ndi zotsatira zochepa pakupanga kwa jenereta, koma kumayambitsa kupatuka kwakukulu kwa kutentha kwa hydrogen kozizira kwa hydrogen. ngozi ina.Komanso, katunduyo akachuluka, ngati ntchitoyo iyambiranso, imayambitsanso kusintha kwa kutentha kwa haidrojeni potulutsira zoziziritsa kukhosi zina zomwe zimagwira ntchito bwino, zomwe zimakhala zovuta kwambiri kuti ogwira ntchito asinthe.Pakalipano, malinga ndi gawo lalikulu la hydrogen lotayirira la majenereta a magetsi osiyanasiyana ndi hydrogen yozizira, mipope ina yamadzi ozizira yomwe ikutuluka imatsekedwa ndi mapulagi.Mwanjira iyi, kuchuluka kwa mipope yoziziritsa yothandiza kumachepetsedwa, zomwe zimakhudza kuziziritsa, ndikudzipatula mobwerezabwereza ndi plugging chifukwa cha ntchito.chachikulu.Kwa zaka zambiri jenereta yakhala ikugwira ntchito, chozizirira chatsopano chiyenera kusinthidwa kotheratu pamene unityo yatha kukonzedwa.Ngati zatsimikiziridwa kuti chitoliro cha madzi ozizira cha stator chikutha, makinawo amatha kutsekedwa kuti akonze.

3. Kuchuluka kwa chinyezi cha haidrojeni m'maseti a jenereta ya dizilo kumawononga ma jenereta.

① Chepetsani mulingo wotsekemera wa ma stator end windings, zomwe zimapangitsa kuti pakhale njira yotulutsira pamadzi.

②Chepetsani kukana kotsekera kwa rotor ndikufulumizitsa kuchitika kwa zolakwika zapansi kapena zapakati-pang'onopang'ono pamakona a rotor omwe ali ndi vuto la kutchinjiriza.

③Kufulumizitsa kuyambitsa ndi kukula kwa ming'alu yopangidwa ndi haidrojeni mu mphete ya rotor.

4. Magwero akuluakulu amadzi ndi zifukwa za chinyezi cha hydrogen wambiri m'maseti a jenereta ya dizilo.Gwero lalikulu la madzi:

① Pali kutayikira mumayendedwe amadzi ozizira ndi mapaipi oziziritsa wa haidrojeni mumayendedwe a stator.

②Madzi obweretsedwa ndi hydrogen supplement

③Chinyezi chomwe chimabweretsedwa m'makina ndi mafuta a matailosi osindikiza.Zowonongeka za kapangidwe ka chisindikizo cha nthunzi ya turbine ya nthunzi-dongosolo lalikulu lamafuta-thanki yayikulu yamafuta-jenereta yosindikiza mafuta - dongosolo la hydrogen-mkati mwa jenereta.chifukwa chachikulu:

①Madzi omwe ali mumafuta osindikizira ndiwokwera kwambiri.

②Kukhudzika kwa valve balance mu makina osindikizira mafuta ndikotsika kwambiri.

5. Main luso miyeso ya haidrojeni kutayikira wa seti jenereta dizilo.

① Imatengera valavu yowoneka bwino kwambiri, ndipo mawonekedwe ake amasinthidwa kuchoka kumtunda kupita ku ofukula, ndipo zotsatira zake zimakhala bwino.

②Chida cha vacuum dehumidification chimayikidwa polowera mafuta osindikizidwa.

③Sinthani mphamvu ya dehumidification ya chowumitsira haidrojeni.

Njira zowonjezera mphamvu ya hydrogen dryer:

1. Wonjezerani kuchuluka kwa mpweya wa haidrojeni ndikuchepetsa chinyezi pachotulutsa chowumitsira.

2. Ntchito yosasokonezeka ya chowumitsira.

3. Ngati chipangizocho sichikugwira ntchito ndipo jenereta ikusunga mphamvu ya haidrojeni, chowumitsira chiyenera kukhala chikugwirabe ntchito.Cholinga cha izi: mbali zonse za mkati mwa makinawo zimakhala ndi kutentha kochepa, makina osindikizira mafuta akugwirabe ntchito, madzi okhudzidwa akadali akuwunjikana, ndipo kufalikira kwa hydrogen mumakina kumayimitsidwa.Zonsezi zimatha kuwonjezera chinyezi cha haidrojeni m'malo ochepera mkati mwa makina pafupi ndi matailosi osindikizira, ndipo ndikosavuta kufikira mame.

Kuyanika kwa haidrojeni pamajenereta a 300MW makamaka kumagwiritsa ntchito zowumitsira ma hydrogen.Mfundo yake ndi: chipangizo cha firiji chogwiritsira ntchito Freon compressor kuti apange malo otsekedwa otsika kutentha.Mbali ina ya haidrojeni yonyowa mu jenereta ikadutsa m’danga limeneli Chinyontho cha hydrogen chonyowacho chikafupika n’kukhala mame, chimakhala m’chichipangizocho ndipo chimatulutsidwa nthaŵi ndi nthaŵi kuti chikwaniritse cholinga choumitsa haidrojeniyo.Zomwe zimakhudza chowumitsira wa hydrogen: kutentha kwa malo opindika a chipangizo cha firiji.Kutsika kwa kutentha, kumakhala bwinoko.Izi zikugwirizana ndi mphamvu ya chipangizo cha firiji, kuchuluka kwa malo, kuthamanga kwa hydrogen yonyowa, ndi kutentha.Pali zofooka zina pakugwiritsa ntchito chowumitsira ichi:

1. Kutentha kotuluka kwa chowumitsira kumatha kufika -10 ℃ ~ -20 ℃, ndipo digiri yake yowumitsa ndi yochepa.Malo osinthira kutentha apitilizabe kuzizira, zomwe zidzakulitsa kukana kwamafuta ndikuchepetsa kuyanika.Kutentha kozizira kumapangitsa kuti chowumitsira chizigwira ntchito pang'onopang'ono ndipo chinyezi cha haidrojeni mumakina chimakwera.Pakadali pano, jenereta nthawi zambiri imakhala ndi zowumitsira ma haidrojeni awiri.Ndikofunikira kuyang'ana ngati mawonekedwe ogwirira ntchito ndi olondola kuti muwonetsetse kuti zowumitsa ziwirizi zimagwira ntchito mosinthana.

2. Dongosolo la kufalikira kwakunja silinasinthe, ndipo limayendetsedwabe ndi kusiyana kwa mafani amagetsi kumapeto kwa jenereta.Chigawocho chikatsekedwa, vuto lotaya kuyanika mu makina likadalipo.Chifukwa chake, pambuyo pake jenereta yamagetsi yatha ntchito, iyenera kusinthidwa ndi mpweya posachedwa kuti mupewe condensation ya haidrojeni mu jenereta.

3. Kutentha kwa hydrogen kumachepetsa (5 ℃-20 ℃), ndipo kutentha kwa haidrojeni mu makina kumafika 40 ℃.Ziwirizi zisanasakanizidwe, ndizotheka kwathunthu kuti ma end windings a stator kapena mphete ya rotor idzagonjetsedwa ndi kutentha kochepa mosalekeza kwa nthawi yaitali.Kuphwanya, kuyika chiwopsezo ku ntchito yake yotetezeka.

Poona chodabwitsa ichi mu jenereta, kulingalira kuyenera kuganiziridwa ngati mtundu watsopano wa regenerative adsorption drying system ungagwiritsidwe ntchito posankha zida zowumitsa hydrogen.
