Sisitemu yo guhumeka ibyuma ntabwo ari ibikoresho gusa-niwo murongo wa mbere wo kwirinda guhumeka, guturika, hamwe nubushyuhe. Mubikorwa-byukuri, twabonye kunanirwa guhumeka bitera kwimuka byihutirwa-atari ukubera ko abafana bavunitse, ahubwo ni ukubera ko bitasobanuwe neza gukusanya methane, gupakira ivumbi, cyangwa itandukaniro ryumuvuduko utunguranye. Ibyabaye mu 2023 byabereye mu birombe bya Shandong bidafite ingufu birabyemeza: umuyaga wambere wa axial wujuje intego yo gutembera kwikirere ku mpapuro ariko ntushobora kwihanganira umuvuduko uhagaze hejuru ya Pa 1800 mugihe kurwanya filteri byiyongereyeho 40% nyuma yamasaha 72 yo gukomeza gukora. Nibwo kwizerwa kureka kuba theoretical.
Kuki "Umuyaga uhagije gusa" ni Ibitekerezo Biteye Akaga
Ibirombe byo munsi yubutaka bisaba ibirenze umusaruro mwinshi. Bakenera igisubizo cyingirakamaro, ubunyangamugayo bwubatswe munsi yinyeganyeza, hamwe n imyitwarire idahwitse mumyuka iturika. Urukurikirane rwa FBD (dⅠ) ruturika-rutera-rutera-rutera-ruzunguruka ruzunguruka rwumuyaga waho-rukoreshwa mu birombe birenga 37 bigoye cyane mu Bushinwa no mu majyepfo y’amajyepfo ya Aziya - byakozwe mu rwego rwo kuziba icyuho. Igikoresho cyayo gifite moteri ebyiri, irwanya guhinduranya itanga 22-28% byumuvuduko mwinshi kuruta icyiciro kimwe cya axial yibice byinjiza imbaraga. Ikirushijeho kunenga, icyiciro cyayo cya mbere, Icyiciro cya 1 ibyemezo biturika-bidafite ishingiro-byubatswe muri moteri yimiturire ya geometrike, uburyo bwo gufunga shaft, hamwe nuburyo bwo guta ibyuma byangiza.
Ariko imikorere ntabwo ireba gusa. Byerekeranye nibibaho mugihe ubushyuhe bwibidukikije bugera kuri 52 ° C, ubuhehere bugereranije buzamuka hejuru ya 95%, naho umukungugu wa silika urenga 8 mg / m³. Abafana basanzwe bafata. Umukandara utwara kunyerera. Imodoka ihindagurika. Niyo mpamvu guhitamo ibyuma byangiza umuyaga bigomba gutangirana no gushushanya ibidukikije-ntabwo ari gushakisha kataloge. Twabonye abakiriya bagabanya igihe cyo gutangiza 60% mugihe basangiye raporo zisesengura gazi ya borehole na gahunda yo gutwara amabuye ya buri munsi mbere yo kurangiza gutoranya abafana. Amakuru nyayo atsindira ibitekerezo buri gihe.
Ibintu bitatu bitaganiriweho muburyo bwa Mine Mine Ventilation Igishushanyo
- Ubunyangamugayo buturika bugomba kurenga moteri. Abafana bapimwe kubidukikije bya Zone 1 biracyananirana niba imiyoboro ya inlet idafite umurongo uhoraho cyangwa niba icecekesha kirimo ibyuma bidafunze. Urukurikirane rwa FBD ruhuza imishumi yemewe yubutaka mu buryo butaziguye - nta murima uhindurwa ukenewe.
- Gukoresha umukungugu ntabwo ari ubushake-ni uguteranya. Umufana utanga 12,000 m³ / h mugitangira agabanuka kugeza kuri 9.300 m³ / h nyuma yiminsi 14 atabungabunzwe niba gushungura inlet bidahagije. Abafana ba Titanium-yagenewe kwangirika kwinshi, ahantu hahanamye cyane-bakomeza> 94% byumuyaga mwinshi mugihe cyiminsi 30 utabanje gukora isuku.
- Igenzura ibibazo byihutirwa. Imiyoboro ihindagurika (VFDs) igomba kwitwara mumasegonda 1.2 kuri CO sensor trigger. Ibice bifite analog-yonyine yo kugenzura byongeweho amasegonda 4-7 yubukererwe - igihe gihagije cyo kwibanda kuri metani kurenga 5% LEL kumupaka uhagarara.
Iyo Off-the-Shelf idafite umutekano uhagije
Bamwe bashobora kuvuga ko abakunzi binganda basanzwe bakora neza hamwe nibindi bikoresho byumutekano. Ariko, kongeramo ibintu biturika bitagaragara hanze yumufana rusange-intego ya axial itera amacupa yumuriro, igabanya serivisi, kandi ikuraho ibyemezo byumwimerere. Ikirushijeho kuba kibi, itangiza ingingo nshya zo kunanirwa: gutakaza gasketi, gutakaza imiyoboro ya kashe, hamwe numunaniro ukabije wiring. Kwimenyekanisha ntabwo bijyanye no kwinezeza-ni ugukuraho intera aho ibyago byibanda.
Zibo Hongcheng Fan Co., Ltd. yubaka iri hame mubikorwa byaryo. Iyo ikirombe cy'umuringa muri Yunnan cyari gikeneye umufana ushoboye umuvuduko wa 3,200 Pa kuri 8.500 m³ / h mugihe ukora ubudahwema kuri 75 ° C yubushyuhe, injeniyeri ntabwo yahinduye moderi ihari. Bongeye gukoresha imyirondoro yerekana imyirondoro muri ANSYS CFX, bahitamo Inconel 625 ya rot ya hub, kandi bemeza kwihanganira kwagura ubushyuhe mumasaha 120 yo gutwikwa. Igisubizo? Igice cyemewe kuri GB 3836.1–2021 na ISO 8573–1 Icyiciro cya 2 cyo kwanduza uduce - byatanzwe mu byumweru 11, ntabwo ari amezi atandatu.
Ibizaza nyuma ya fagitire ifite akamaro kanini
Icyuma gihumeka cyicyuma ntigishobora kubona agaciro mugihe cyo kwishyiriraho-kigaragaza mugihe cyagatatu cyicyumweru cya 17. Nibwo ihindagurika ryinyeganyeza ryerekana kudahuza, mugihe ubushyuhe bwubushyuhe bugaragaza amavuta adahuye, kandi mugihe logique yo kugenzura yerekana amakosa yibikoresho. Zibo Hongcheng Fan Co., Ltd ikubiyemo kwitegura kwisuzumisha kure mubice byose bya FBD na titanium: Inkunga ya Modbus TCP, ubushyuhe bwubwato / igitutu / ibyuma byinyeganyeza, hamwe na software igezweho-igenzura logique. Abatekinisiye bo mu murima ntibategereza gusenyuka-babona gutandukana kuri 3% amplitude yiyongera, ntabwo 30%.
Serivisi ntabwo ikora. Birahanura. Itsinda ryabo ryubaka ryasuzumye ibishushanyo mbonera byumwuka mbere yo kubyara - ntabwo ari ukuzamura, ahubwo bireba ibendera ryuburebure budahuye, imivurungano iterwa ninkokora, cyangwa ubugororangingo bushingiye ku butumburuke buhindura ibyifuzo bya feri imbaraga zingana na 11%. Ibyo kwitondera birinda guhindagura imirima ihenze kandi bikomeza inzira zo guhumeka kubahiriza ubuziranenge bwumutekano wa AQ 2013–2018.
Guhumeka-umutekano uhumeka nta mwanya wo gutandukana. Buri cyuma gihumeka kigomba gusubiza ibibazo bitatu mbere yo koherezwa: Birarokoka ibidukikije? Irasubiza ibimenyetso byiterabwoba byihuse kuruta igihe cyabantu? Inkunga yayo yibidukikije iteganya uburyo bwo gutsindwa - ntabwo ari inyandiko gusa? Zibo Hongcheng Fan Co., Ltd. irasubiza yego - ntabwo ari ibisabwa byo kwamamaza, ahubwo ni raporo y'ibizamini, ibiti byo mu murima, hamwe n’ibindi bice byubugenzuzi. Kuberako munsi y'ubutaka, umwuka wo mu kirere ntupimwa muri metero kibe kumunota. Bipimirwa mubuzima burambye, guhinduranya birangiye, kandi byihutirwa birindwa.
