A gutsindwa kw'inkoni yo hasihafi ya yose ntiyigera yitangaza. Inkoni ikomeza guhagarara, agakoresho gakomeza kumurika hejuru y’urwego, kandi akenshi mbona ingese yabonetse gusa binyuze mu isuzuma ryananiwe ryo kwirinda ubutaka - cyangwa ikirenzeho, ikosa ritabona inzira yo gutaha. Mbona imiterere ine y’ubucamanza mu mafoto y’abaguzi banyoherereza: yagabanijwe hose n’ubutaka bukaze, yaciwe ingingo n’imashini zitandukanye z’icyuma, yakuwemo mu mezi menshi n’umuyoboro wa DC utemba, cyangwa yakuwemo imyobo miremire na bagiteri zigabanya sulfate. Buri buryo bufite imbarutso itandukanye, umukono utandukanye, kandi - igice cyo kugura gishobora gukora - ubwirinzi butandukanye. Ndanyura muri byose bine mfite amakuru y’ubutaka inyuma yabyo, amanota y’ubutaka ushobora gukoresha ku rubuga rwawe, n’uburyo twubaka inkoni zifatanye n’umuringa ku ruganda rwacu rwa Xinchang kugira ngo turwanye buri imwe.
TL;DR — Abicanyi bane, bashyizwe mu byiciro hakurikijwe inshuro mbabona
- Kwangirika k'ubutaka kimweni cyo cyica inkoni za galvanisme mbona zaracukuwe: inyigo y’ahantu 23.000 yakozwe ku bigega byo munsi y’ubutaka yasanze ubushuhe bw’ubutaka buri hejuru ya 17.5% ari byo bituma chloride irushaho kuba mbi, ari nayo mpamvu inkoni imwe imara imyaka ibarirwa muri za mirongo mu butaka bwumutse bw’umucanga no munsi y’imyaka icumi mu ibumba ritose.
- Kwangirika kwa Galvanicyibasira ingingo z’ibyuma bivanze: umuyoboro w’umuringa uhujwe n’icyuma gikozwe mu cyuma ...
- Umuyoboro wa DC utembani cyo cyica vuba cyane: Uburyo bwo kugarura ubutaka bwa HVDC butera amperes ibihumbi mu butaka, kandi electrodes hafi y’umuhanda wa gari ya moshi, inkingi z’ubutaka za HVDC, cyangwa sisitemu zo kurinda katodike zishobora gutakaza icyuma mu mezi menshi aho kuba imyaka ibarirwa muri za mirongo.
- Nyita kongo iterwa n’ibinyabuzima (MIC)umwicanyi wihishe: bagiteri zigabanya sulfate mu butaka budafite umwuka, pH 6-8 byongereye igipimo cya corruption cy'icyuma inshuro esheshatu mu bizamini byagenzuwe, kandi umuyoboro mushya wagaragaye ko wananiwe kugera kuri MIC mu mezi 8 gusa.
- Ubwugarizi butangirira ku ikoti rihoraho rya noble-metal: inkoni zacu zifatanye n'umuringa zifite urwego rw'umuringa rwa electroplated rufite nibura 0.254 mm ku buziranenge bwa 99.95% - nta zinc yo gutamba, nta gihe cyo gutwikira bagiteri, byemejwe n'ingufu za 90° kuri radius ya 100 mm kuri buri gice.
Uburyo bwa 1 — Ingwara y'ubutaka isanzwe: Inyoroshya ituze
Ndibutsa abaguzi ko buri electrode itwikiriwe iba mu karemangingo k’amashanyarazi, kaba kakozwe cyangwa katakozwe. Nsobanura ubushuhe bw’ubutaka nk’amashanyarazi, umunyu nk’igena uburyo bwo kuyobora amashanyarazi, naho inkoni nk’iyoni y’icyuma itakaza iyoni bitewe na ayoni, umwaka ku wundi. Ishyirahamwe ry’Abanyamerika ry’Abagabuzi b’Ibintuamakuru yerekeye ingese y’ubutaka, yubatswe ku bushakashatsi bwa Dr. Warren Rogers bwakorewe ahantu harenga 23.000 ho kubika ibigega byo munsi y’ubutaka, ipima igitera ingirabuzimafatizo kuba mbi: kloride, ubushuhe, na pH byiganjemo, aho ubushobozi bwo guhangana n’ibiza bugira uruhare rwa kabiri. Icyagaragaye cyane na Rogers ni urugero - munsi ya 17.5% by'ubushuhe bw'ubutaka, ubushyuhe bwa kloride ntibushobora gutuma igipimo cya ruswa kigabanuka; hejuru yabwo, kloride zitera cyane. Nfata ubutaka buri munsi ya pH 7 nk'ubwiyongere bw'ibyangiritse.Kubera ko ubushuhe, atari kalendari, ari bwo bushyiraho isaha yo kwangirika, urutonde rw'amakuru y'inkoni ya galvanized "imyaka 10-20" ihisha ikwirakwira rikomeye: inkoni imwe ni umutungo w'imyaka 25 mu mucanga watose n'imyaka 7 mu ibumba ritose kandi rifite umunyu.
Nasomye ikimenyetso cy’ubugenzuzi nk’aho kiri ku rugero rwo hasi cyane, kandi kibi cyane ku murongo w’ubutaka. Ntanze interuro yacyo ya mm 300 hejuru kuko kiri ku murongo wa ogisijeni hagati y’ubutaka bwo hejuru bufite umwuka n’ubujyakuzimu butagira umwuka, bityo umwuka utandukanye utera neza aho inkoni yinjirira mu butaka - ahantu nta muntu ucukura. Ku bijyanye n’imyenda yo kwigomwa, imibare ni iy’umurongo kandi ntibabarira: zinc irinda gukoreshwa, bityo ubuzima ni nk’imyenda yo kwigomwa igabanyijwemo igipimo cya ruswa yo mu gace.Kubera ko ikoti ry’icyuma cyiza ririnda mu kwikuramo aho kwigomwa, urwego rw’umuringa rudasibangana ntirushobora kubara ibi bihe - niyo mpamvu ibikoresho bifite ubutaka bwangiza byahagaritse kugura amabati mu myaka yashize.
Uburyo bwa 2 — Ingufu ya Galvanic: Ingingo zihindura imiterere y'urukuta
Dore uburyo bwo gutsindwa mbona mu mafoto yo gucukura imirambo nibura buri mezi make: umugozi w'inkoni uba umeze neza, ariko icyuma kiri muri mm 100 uvuye aho gihuriye gihita gicika igicucu. Ibyo nbyita galvanic corrosion, kandi fiziki yayo yoroshye cyane. Nk’uko bigaragara muriUbuyobozi bw'ishyirahamwe ry'Abanyamerika ryita ku byuma bitandukanye by'ibyuma, akaremangingo ka galvanic gakeneye ibice bine - anode, cathode, electrolyte, n'inzira y'umuyoboro w'amazi ugaruka - kandi ubutaka butose butanga icya gatatu mu gihe insinga yawe yo guhuza itanga icya kane. Huza sisitemu yo gusimbuza ishingiye ku muringa n'iminara y'icyuma cya galvanic, uruzitiro, cyangwa icyuma gikomeza, maze zinc iba anode: irangirika cyane kugira ngo irinde umuringa. Itegeko ryacu, ryakuwe muri AGA, ni igipimo cy'ubuso bwa anode-kuri-cathode cya nibura 10: 1; hindura - agakoresho gato gapfundikiye ka zinc cyangwa bolt ihambiriye umuyoboro munini w'umuringa - kandi igice gito gishobora kuribwa mu gice gito cy'ubuzima bw'umuyoboro. Iryo huriro rigaragaza ko n'amazi atemba ava ku buso bw'umuringa atwara umuringa uhagije washongeshejwe kugira ngo wibasire zinc iri hasi.
Kubera ko icyuma gihuza ibyuma gikoresha amashanyarazi (galvanic couple) gishyiramo ibyangiritse byose ku bikoresho bihuza ibyuma, icyuma gishobora kugeragezwa imyaka myinshi mu gihe ibyuma bihuza amashanyarazi byegereje gucika intege buhoro buhoro - kandi iyo icyuma gihuza amashanyarazi kivuyeho, inkoni yakoreshejwe iba umutako.Mfata ibikoresho byo guhuza nk'ikintu cyihariye, ntabwo ari igitekerezo cya nyuma, kandi niyo mpamvu dukoresha imashini zacuibifunga by'ubutaka birwanya ingesemu muringa usanzwe cyangwa ukozwe mu gikombe: guhuza ubushobozi bwa electrochemical bwa conductor bikuraho ubwo bufatanye aho kubucunga.
Uburyo bwa 3 — Umuyoboro w'amashanyarazi utemba: Electrode iribwa n'amashanyarazi
Nubaha uburyo bwa gatatu cyane: bushobora kwica electrode ikomeye mu ngengo y'imari imwe, kandi ntaho bihuriye n'ubutabire bw'ubutaka. Aho DC current inyura hose mu isi - amashanyarazi agaruka, sisitemu zo kurinda cathodic, cyane cyane ihererekanya rya HVDC rikora mu buryo bwo kugarura ubutaka - mfata icyuma icyo ari cyo cyose gitwikiriwe hafi aho nk'aho gishobora gufata uwo muyoboro no kuwusohora. Mbona icyuma gishonga aho umuyoboro uva hejuru. Nishingikirije ku bushakashatsi ku kubangamira umuyoboro w'amazi wa HVDC wasohotse binyuze muriIsomero ry'Igihugu ry'Ubuvuzi rya Amerika (PMC)ku gipimo: iyo umurongo wa DC ukorana n'igaruka ry'ubutaka, electrode yo hasi itera imigezi "ishobora kugera ku bihumbi bya amps," igashyiraho umurima wa DC udahinduka mu butaka wihutisha ingese y'amashanyarazi y'inyubako z'icyuma zihishe hafi yacyo, hamwe n'igitero kibi cyane ku byangiritse byo gutwikira no gusohokera kw'umugezi.
Ndasanga ikimenyetso cy’aho hantu kidahinduka iyo ubimenye: gutakaza icyuma vuba, ahantu runaka ahantu hatandukanye aho gucika intege, akenshi bihura n’aho gikomoka, bigatera imbere mu mezi cyangwa mu myaka mike.Kubera ko ingese iterwa n’amazi aturutse hanze aho guterwa n’ibinyabutabire by’ubutaka bwo mu gace runaka, nta bunini bw’igitambaro ku isi bushobora kumara igihe kirekire - ubwirinzi ni ahantu haherereye, intera yo gutandukanya, ingamba zo gufatanya, no gukurikirana, si inkoni iremereye.Ndahagarika kuvuga ku bijyanye no gusiga amarangi maze ntangira gusaba ko habaho inyigo yo kubangamira ibidukikije mu gihe umushinga uvuga ko ari hafi ya gari ya moshi ya DC, inkingi y'ubutaka ya sitasiyo ya HVDC, cyangwa ahantu hafite uburinzi bwa cathodic.
Uburyo bwa 4 — MIC: Bagiteri zishyira mu cyuma hasi
Uburyo bwa kane ni bwo abaguzi badatekereza cyane kandi bagomba gutinya cyane mu butaka bukwiye. Ingufu ziterwa na mikorobe ziterwa na biofilms - kandi bagiteri zigabanya sulfate (SRB) zikunda kubaho neza aho electrodes zitera ubutaka ziba: ubutaka budafite umwuka, butwikiriye amazi, bufite sulfate kuri pH 6-8. Nsanga imibare yapimwe idasanzwe. Mu bushakashatsi bwakozwe n'urungano ku byuma byatwikiriwe mu butaka budafite aside bwasohotse muriImyambaro ya MDPI (2021)SRB yongereye igipimo cyo kwangirika kw'icyuma inshuro esheshatu ugereranije n'imiterere yacyo idahumanye, uburebure ntarengwa bw'icyobo bwariyongereye kuva kuri 2.32 μm bugera kuri 6.01 μm mu gihe cy'igeragezwa rimwe, kandi abanditsi bavuga ko hari inkuru yanditse aho umuyoboro mushya wananiwe kugera kuri MIC mu mezi 8 gusa. Igitero kirimo kugabanuka, ntabwo kirimo kugabanuka: hari imiyoboro miremire munsi y'igisenge cya biofilm, ari nayo mpamvu ahantu ha MIC hashobora gutoboka mu gihe icyuma cyo hafi aho gisa n'aho kitakozweho.
Kubera ko SRB ikenera imiterere idakora neza kandi ikaba na sulfate, nshobora guhanura ingaruka za MIC mu bushakashatsi bwakozwe aho hantu — ibumba rikungahaye ku bimera, ibishanga, imirima y’ubuhinzi, n’ubutaka bwuzuye amazi bufite impumuro y’igi riboze (H₂S) ni byo bikunze gutera ubwinshi bw’ibimera.Mbona uburyo bubiri bwo kwirinda bufitiye akamaro electrodes. Ubwa mbere ni uburinzi bw'inzitizi: bagiteri zikoresha irangi ry'ibiruhuko, bityo ikoti rihoraho, ridafite inenge ni ryo rikoreshwa imbere - imiterere y'ibicuruzwa byacu isaba ko umuringa ukomeza neza nta mvune, imyobo, cyangwa imyenge kubera iyi mpamvu. Dukoresha shimi yo gufunga inyuma: bentonite na conductive backfills bihindura ubushuhe n'ibidukikije bya ionic bikikije inkoni, kandi aho byuma annulus bicisha inzara biofilm ya electrolyte yayo.

Umuhanga mu gupima ingaruka z'ingaruka z'ubushyuhe ku butaka
Uburyo Twubaka Inkoni Zirwanya Zose Zine
Gushushanya umwicanyi umwe ukoresheje ikintu kimwe bisa n'ubwumvikane, ariko ishingiro rihurira ku kintu kimwe: ikoti rinini, rihoraho, ry'icyuma cyiza rifatanye n'inkingi y'icyuma.Inkoni zo mu butaka zirwanya ingese zikoreshwa mu gutwikaDufate urwego rw'umuringa rwakozwe n'amashanyarazi rufite nibura 0.254 mm — 254 μm by'umuringa wa 99.95%-purity udafite zinc yo gutambagira, kandi iyo ibisabwa byacu byo gukomeza iminsi mikuru nta mpungenge bifite, nta nenge iyo biofilm cyangwa galvanic couple bishobora gukoresha. Mu nkoni zacu, umuringa w'icyubahiro usimbuza zinc yo kubara igihe cyo kwangirika k'ubutaka; kurwanya galvanic, guhuza umuringa n'inkoniibipfundikizo by'umuringaIgumana ingingo zose ku ruhande rumwe rw'uruhererekane rwa galvanic; kuri MIC, ikoti rikomeza ryemewe rikuraho bagiteri zikingirwa mu minsi mikuru. Umuyoboro w'amazi utemba gusa ni wo uba hanze y'ibikoresho - kandi kubera ibyo, tubwira abaguzi mu by'ukuri gutera inkunga inyigo y'ihungabana.
Ndashimangira ko ikoti ricagagurika mu gitereko ari ikoti ricika mu butaka. Dufite imbaraga zo gukurura kuri ≥580 N/mm² hirya no hino.inkoni y'ubutaka ipfutse umuringaIngano — uburebure bwa mm 14.2–25, uburebure bwa metero 1.2–3.0 — igumana ubugororangingo muri mm 1 kuri metero, kandi irenga uburebure bwa 90° kuri radius ya mm 100 nta gucikamo umuringa cyangwa ngo yangirike ku ntera y'icyuma n'umuringa. Amarembo atandatu ya QC ahera ku igenzura ry'icyuma kijya mu nzu kugeza ku igenzura rya nyuma mbere yo kohereza, ku bice 50.000 buri kwezi.Icyiciro cy'inkoni yo hasi n'inkoni y'ubutaka— umuringa ufatanye, umuringa w’umwimerere, galvanized, na electrode zidasanzwe — zirahari ku buryo ibisobanuro bishobora gukurikira ubutaka, atari ibinyuranye n’ibyo.
Gusana ubutaka: Gufata ibyangiritse mbere yuko buhagarara
Ndetse n'agace kabigenewe neza ndagaha umuvuduko wo kugenzura, kuko ingese ni mbi kandi impapuro ni ibinyoma. Inama nagira ku baguzi ku bijyanye no kubungabunga ni ngufi kandi ntizishimishije: gerageza ikizamini cyo kurwanya ubutaka buri mwaka, kuko intera izamuka ni yo igaragara; banza ucukure 300 mm hejuru y'inkoni imwe kuri buri gice cy'agace k'ubutaka mu gihe cy'imyaka myinshi, kuko umwuka uhindagurika utera ibitero ku murongo w'ubutaka, aho nta muntu ureba; genzura amashanyarazi ashoboka mu gihe cy'ibura ry'ibikoresho, kuko igitero cya galvanic gitangira ku miyoboro; kandi nyuma yo kubaka gari ya moshi, imiyoboro, cyangwa HVDC iri hafi aho, ongera usubize ikibazo cy'amazi yataye umurongo, kuko ikintu cyica vuba cyane ni icyo ubushakashatsi bwawe bw'ubutaka butigeze bubona.
Ibibazo Bikunze Kubazwa
Inkoni y'ubutaka igomba kumara igihe kingana iki mu butaka?
Igisubizo cyanjye cy'ukuri ni “biterwa n'uburyo ubutaka bwawe bukoresha.” Nabonye inkoni za galvanised mu butaka bwiza, butose amazi, kandi butagira aho bubogamiye zimara imyaka 10-20; mu butaka butose, bufite aside kandi bufite chloride inkoni imwe ishobora gukoreshwa mbere cyane, kuko zinc irinda gukoreshwa. Inkoni zifatanye n'umuringa zifite ikoti rihoraho rya mm 0.254 zigenwa buri gihe mu gihe cy'imyaka 30-50 bitewe nuko umuringa utagira aho ugarukira. Ubushobozi bwo guhangana n'ubutaka, pH, n'ubushuhe bw'aho hantu ni ingenzi kurusha umubare uwo ari wo wose w'amakuru - zivane muri raporo ya geotekinike mbere yo kugereranya igihe serivisi ikorerwa.
Ni ibihe bimenyetso bya mbere by'uko inkoni y'ubutaka yangiritse?
Hejuru y’urwego, hafi ya byose - ni byo bituma ingese iteje akaga. Ikimenyetso cya mbere cyizewe ni ukwiyongera kw’ibizamini byo kurwanya ubutaka buri mwaka. Mu gucukura imirambo, nasomye uburyo bw’icyuma: no kugabanya ukoresheje igice cy’ubutaka gifite umugongo ni ingese imwe; igihombo cy’icyuma cyinjijwe muri mm 100 uvuye ku gipfundikizo kiba cya galvanic; igihombo cyimbitse kiri hafi ya gari ya moshi cyangwa ibikorwa remezo bya HVDC ni amazi adakora; kandi ibyobo byimbitse biri munsi y’umukara, utuntu twose twangiritse ni MIC. Genzura mm 300 hejuru byibuze inkoni imwe kuri buri gice mu gihe cy’imyaka myinshi - niho ibimenyetso byihishe.
Kuki inkoni z'umuringa zifatanye ziramba kurusha iza galvanized mu butaka bushyushye?
Twubaka ibirahure bibiri dukurikije ingamba zitandukanye. Ndasobanura ko zinc ari ikintu gitanga umusaruro: irangirika kugira ngo ikingire icyuma, bityo ubuzima bwo kuyikoresha ni ubunini bw'ibirahure bigabanyijwe n'igipimo cy'ubushyuhe - mu butaka bushyushye, ubwo bwigabanyirize burushaho kuba bubi vuba. Twishingikiriza ku butunzi bw'umuringa: ikoti rikomeza gukoreshwa n'amashanyarazi rya mm 0.254 cyangwa rirenga rikuraho electrolyte mu cyuma, bityo nta kubara igihe cyose ikoti rigumye rimeze neza. Mu iduka ryacu, gukomeza ikoti - nta mvune, imyobo, cyangwa imyenge - no gukora neza kw'ikoti kuri radius ya mm 100 bifite agaciro kangana n'ubugari ku rupapuro rw'amakuru kubera iyo mpamvu.
Ese nshobora guhuza umuringa ukoresheje icyuma gikozwe mu cyuma ...
Urashobora, ariko uri kubaka akaremangingo ka galvanic, bityo ubikora nkana. Ndaburira abaguzi ko ubutaka butose ari bwo butuma electrolyte yawe ifatana kandi kontineri yawe yo guhuza ari yo nzira igaruka; irangi rya zinc rihinduka anode kandi rigatanga ubwitange. Ishyirahamwe ry’Abanyamerika ryita ku banyagalvanic risaba ko igipimo cy’ubuso bwa anode-to-cathode cyaba nibura 10:1, bigatandukanya ingingo mu buryo bw’amashanyarazi aho bishoboka, kandi ntibyigere bireka igice gito cya zinc gifatana mu gace kanini k’umuringa. Aho igishushanyo mbonera cyemerera hose, huza umuringa n’umuringa - ibyuma bihuye bikuraho burundu ibyo bintu aho gucunga ibyangiritse.
Ese ubushobozi bwo guhangana n'ubutaka bugira ingaruka ku kwangirika kw'inkoni ndetse no ku kwangirika k'urukuta?
Yego, kandi igipimo kimwe ni cyo kibigaragaza byombi. Ubutaka budashobora kwangirika cyane akenshi buba buke kuko bufata ubushuhe bwinshi n'imyunyu yashongeshejwe - ibi bigatuma buba ahantu heza ho gukurura ubutaka ndetse n'amashanyarazi akomeye yo kwangirika. Nkurikiza itegeko rya AGA nubwo amakuru akoreshwa mu kwangirika k'ubutaka afata kwangirika nk'ikintu cya kabiri inyuma ya kloride, ubushuhe, na pH: munsi ya 50 Ω·m, tekereza ko aho hantu hashobora kwangirika kugeza igihe shimi ibivuze ukundi, kandi ikagaragaza ikoti rikwiye.
Ese hari ahantu hatazabaho irangi ry'inkoni y'ubutaka?
Isomo rimwe, yego: uturere dukomeye tw’amashanyarazi ahindagurika. Nta gisubizo mfite cyo gutwikira aho umuriro wa DC uturuka mu mikorere ya HVDC yo kugarura ubutaka, inzira y’amashanyarazi, cyangwa sisitemu zo kurinda cathodic zinyura muri electrode yawe: igihombo cy’icyuma giterwa na ampere zo hanze kandi gishobora gukuraho irangi shimi yonyine itazigera irusha - inkingi za HVDC zishyiramo irangi rishobora kugera ku bihumbi bya ampere mu butaka. Ubwunganizi ni ubwubatsi, ntabwo ari ugutanga amasoko: inyigo yo guhungabanya, intera yo gutandukanya, imiyoboro y’amazi, n’ibipimo byo kugenzura. Niba umutanga serivisi asezeranya irangi rigabanya irangi rihindagurika, mubaze amakuru y’irirangi - nta na rimwe rihari.
Ni kangahe sisitemu zo gucukura ivumbi zigomba kugeragezwa kugira ngo zirebe niba zangiritse?
Gerageza ubushobozi bwo kurwanya ubutaka buri mwaka kandi ubuhindure - umurongo uhindagurika ni ingese wigaragaza imyaka myinshi mbere yuko unanirwa. Ongeraho uburyo bwo kugenzura: banza ucukure 300 mm zo hejuru z'inkoni zihagarariye buri myaka mike, urebe neza torque-reba clamps zishobora gukoreshwa mu gihe hadakoreshejwe, kandi wongere usuzume niba hari umuyoboro w'amazi wataye umurongo igihe cyose ibikorwa remezo bya gari ya moshi, imiyoboro, cyangwa HVDC bigaragaye hafi aho. Duteganya ahantu hashobora kuba hari ibyago byinshi - amazi yuzuye, umunyu, cyangwa ubutaka bw'inganda - ku mpera ngufi ya buri gice, kuko uburyo bwose bune bukora vuba aho.
Kugena inkoni z'ahantu hashobora kwangirika?
Nyoherereza ubushobozi bwawe bwo guhangana n'ubutaka, pH, ubushuhe, n'ibikorwaremezo bya DC biri hafi yawe — nzagaruka mu munsi umwe w'akazi mfite isuzuma ry'uburyo bukoreshwa cyane n'ibipimo by'inkoni n'icyuma biyisubiza, bishingiye ku bunini bw'ingano n'amakuru yo kuzunguruka yo mu murongo wacu w'ibice 50.000 buri kwezi.Tangira ikiganiro ku rubuga rwacu rwo guhamagara →
