Njodzi dzeHydrogen Leakage yeDiesel Majenareta uye Matanho Ekugadzirisa

Nhasi, Dingbo Power, inogadzira dhiziri jenareta, yakaunza kune vashandisi vakuru njodzi dzekudonha kwehydrogen. dizeli jenareta seti uye mamwe matanho ekugadzirisa.

1. Njodzi dzekudonha kwehydrogen kubva kumajenareta edhiziri.

① Iyo yakatemerwa kukosha kwehydrogen kudzvanywa haigone kuvimbiswa, izvo zvinokanganisa kubuda kwejenareta.

② Kunyanya kushandiswa kwehydrogen kunokonzeresa kugadzirwa kwehydrogen uye kudhura kwakanyanya.

③Iyo jenareta system inogona kubata moto kana kuputika, zvichikonzera kukuvara.

2. Nzira yekuwana sei hydrogen leakage ye diesel generator set.

①Tsvaga panobuda mvura mushure mekunge unit yapera basa.Kazhinji, kuyedza kusimba kwemhepo kwejenareta kunoitwa mushure mekunge hydrogen yatsiva mhepo.

②Tsvaga kuvuza kwejenareta panguva yekushanda, uye shandisa trace hydrogen tester kuti uwane iyo hydrogen leakage nzvimbo.Kana hydrogen ikaonekwa padivi rekubuda kwemvura inotonhorera yehydrogen inotonhorera, zvinofanirwa kutariswa kuti pane kubuda mumvura inotonhorera;kana iyo nitrogen inoyerera mita pamusoro pemvura inotonhorera yakagadzika inofamba, inofanirwa kutariswa kuti pombi yemvura inotonhorera ye stator iri kubuda.

③Isa online inoenderera yekutarisa chiridzwa chehydrogen kuvuza.Mushure mekuwana iyo hydrogen yekudonha poindi, kana jenareta yekupedzisira chivharo kana mamwe majoini maficha, inogona kuvharwa nechisimbiso;kana iyo hydrogen inotonhorera iine kuvuza, inogona kuparadzaniswa yega.Kune 300MW jenareta, kazhinji kune mapoka mana uye anokwana masere Kune inotonhorera, imwe chete yekuzviparadzanisa ine mhedzisiro shoma pane inobuda jenareta, asi inokonzeresa kutsauka kukuru mukupisa kwehydrogen yekubuda kweiyo hydrogen inotonhorera, inova. imwe njodzi.Uyezve, kana mutoro wacho wakakwirira, kana kuvhiyiwa kukatangazve, kunokonzerawo shanduko mutembiricha yehydrogen panobuda mamwe anotonhorera mukushanda kwakajairika, izvo zvinonetsa zvikuru kuti vagadziri vagadzirise.Parizvino, maererano nechikamu chikuru chinodonhedza hydrogen chemajenareta emagetsi akasiyana siyana ndiyo inotonhorera yehydrogen, mamwe mapombi emvura anotonhodza ari kubuda anovharirwa nemapulagi.Nenzira iyi, huwandu hwemapombi ekutonhora anobatsira hunoderedzwa, izvo zvinokanganisa kutonhora mhedzisiro, uye kudzokororwa kuzviparadzanisa uye plugging kukonzera basa.hombe.Kwemakore akawanda jenareta rave kushanda, chinotonhodza chitsva chinofanira kutsiviwa zvachose kana yuniti isingashandiswe kugadzirisa.Kana zvakatemwa kuti iyo stator inotonhorera pombi yemvura iri kubuda, muchina unogona kungovharwa kuti ugadziriswe.

3. Kuwedzeredza hunyoro hwehydrogen mumaseti ejenareta edhiziri kunokuvadza kune majenareta.

① Deredza nhanho yekudzivirira ye stator end windings, zvichikonzera nzira yekuburitsa padivi penzvimbo inodzivirira.

②Deredza kudzivirira kwekudzivirira kwe rotor uye nekumhanyisa kuitika kwekudzika kana kupindirana-kupfupi-kukanganisa kupfupi-mumhepo inotenderera ine hurema hwekudzivirira.

③Kurumidza kutanga uye kukura kwehuwandu hwehydrogen-induced kuparuka murotor guard ring.

4. Zvitubu zvikuru zvemvura uye zvikonzero zvekunyanya kuwanda kwehydrogen humidity mumaseti ejenareta redhiziri.Nzvimbo huru yemvura:

① Pane kuvuza mumhepo inotonhorera inotonhorera uye hydrogen inotonhorera pombi mune stator mhepo.

②Mvura inounzwa nehydrogen supplement

③Kunyorova kunounzwa mumushini nemafuta kubva pachisimbiso tile.Kukanganisa kwechimiro chechisimbiso cheiyo steam turbine-iyo huru sisitimu yemafuta-iyo huru tangi yemafuta-iyo jenareta yekuvharisa oiri system-iyo hydrogen system-mukati mejenareta.chikonzero chikuru:

①Mvura yemvura mumafuta ekuvharisa yakakwira zvakanyanya.

②Kunzwa kwevhavhavha yebhavhari mumafuta ekuisa chisimbiso yakaderera.

5. Main tekinoroji matanho ehydrogen kuvuza kwedhiziri jenareta seti.

① Inotora yakakwira-sensitivity chiyero vharafu, uye chimiro chechimiro chinoshandurwa kubva kune yakachinjika kuenda yakatwasuka, uye mhedzisiro yacho iri nani.

②A vacuum dehumidification mudziyo wakaiswa panzvimbo yekupinza yeyakavharwa oiri system.

③Kuvandudza dehumidification mhedzisiro yehydrogen dryer.

Matanho ekuvandudza maitiro ehydrogen dryer:

1. Wedzera mwero wekuyerera kwehydrogen uye kuderedza humidity panobuda muomesi.

2. Kusavhiringidzwa kushanda kwemuomesi.

3. Kana chikwata chiri kunze kwebasa uye jenareta inochengetedza hydrogen pressure, iyo yakaoma inofanira kunge ichiri kushanda.Chinangwa cheizvi: zvikamu zvemukati zvemuchina zvese zviri munzvimbo yakaderera tembiricha, iyo yekuvharisa mafuta system ichiri kushanda, mvura ine simba ichiri kuunganidza, uye kutenderera kwehydrogen mumushini kunomiswa.Zvese izvi zvinogona kukurumidza kuwedzera hunyoro hwehaidhirojeni munzvimbo isina kukwana mukati memuchina padyo netairi yekuisa chisimbiso, uye zviri nyore kusvika padova.

Kuomeswa kwehydrogen kwemajenareta e300MW kunonyanya kushandisa ma hydrogen dryer.Nheyo yacho ndeiyi: mudziyo wefiriji unoshandisa Freon compressors kugadzira yakavharwa yakaderera-tembiricha condensing nzvimbo.Kana chikamu chehaidhirojeni yakanyorova mujenareta ichipfuura nepanzvimbo iyi Kana mwando uri muhaidhirojeni yakanyorova ukakombwa uye woita dova, unoramba uri mumudziyo wacho uye unobudiswa nguva dzose kuti ubudirire chinangwa chokuomesa haidrojeni.Zvinhu zvinokanganisa iyo hydrogen dryer: tembiricha yenzvimbo inotsikirira yemuchina wefiriji.Iyo yakaderera tembiricha, zviri nani mhedzisiro.Ichi chinhu chine chekuita nesimba remudziyo wefiriji, huwandu hwenzvimbo, mwero wekuyerera kwehydrogen yemvura, uye tembiricha.Pane zvimwe zvinokanganisa pakushandisa iyi dryer:

1. Iyo tembiricha yekubuda yemuomesi inogona kungosvika -10 ℃ ~ -20 ℃, uye dhigirii yekuomeswa kwayo ishoma.Iyo inopisa yekutsinhana pamusoro icharamba iine chando, izvo zvinowedzera kupisa kwekupisa uye kuderedza kuomesa kuita.Defrosting heat inokonzeresa kuti dryer ishande nguva nenguva uye hunyoro hwehydrogen mumushini hunokwira.Parizvino, jenareta rinowanzo shongedzerwa maviri ehydrogen dryer.Izvo zvinodikanwa kuti utarise kana maitiro ekushanda ari echokwadi kuti ave nechokwadi chekuti maomese maviri anoshanda zvakachinjana.

2. Iyo yekunze kutenderera sisitimu haina kushanduka, uye ichiri kufambiswa neiyo fan pressure musiyano pamagumo ejenereta.Mushure mekunge chikwata chavharwa, dambudziko rekurasikirwa kwekuomeswa mumushini richiripo.Naizvozvo, mushure mekuita jenareta remagetsi yapera basa, inofanira kutsiviwa nemhepo nekukurumidza kudzivirira condensation yehydrogen mujenareta.

3. Hydrogen recovery tembiricha yakadzikira (5℃-20℃), uye tembiricha inotonhora yehydrogen mumushini yakakwira kusvika 40℃.Pamberi pezviviri izvi zvakasanganiswa, zvinokwanisika zvachose kuti stator yekupedzisira windings kana rotor guard ring ichaiswa pasi pekushisa kwakadzika nguva dzose kwenguva yakareba.Kukanganisa, kutyisidzira kukushanda kwayo kwakachengeteka.

Mukuona kwechiitiko ichi mujenareta, kufunga kunofanira kupiwa kuti rudzi rutsva rwekugadzirisa adsorption drying system rinogona kushandiswa pakusarudzwa kwehydrogen drying equipment.
