Nekuwedzera kuri kuita pasi rose kutsvaga simba rakachena uye budiriro inoenderera, simba rehydrogen, semutakuri wesimba rinoshanda uye rakachena, riri kupinda zvishoma nezvishoma muchiratidzo chevanhu. Sechinhu chakakosha chinongedzo muinjiniya yesimba rehydrogen indasitiri, tekinoroji yekuchenesa hydrogen haingonei nekuchengetedza uye kuvimbika kwesimba rehydrogen, asi zvakare inokanganisa zvakananga chiyero chekushandisa uye mabhenefiti ehupfumi esimba rehydrogen.
1.Zvinodiwa zvechigadzirwa hydrogen
Hydrogen, sekemikari mbishi zvinhu uye inotakura simba, ine zvakasiyana zvinodiwa zvekuchena uye kusvibiswa kwemukati mumamiriro akasiyana ekushandisa. Mukugadzirwa kwesynthetic ammonia, methanol uye zvimwe zvigadzirwa zvemakemikari, kuitira kudzivirira catalyst chepfu uye kuve nechokwadi chemhando yechigadzirwa, sulfides nezvimwe zvinhu zvine chepfu mugasi rekudya zvinofanirwa kubviswa pachine nguva kuti kuderedze kusvibiswa kwemukati kuzadzisa zvinodiwa. Muminda yemaindasitiri senge simbi, ceramics, girazi, uye semiconductors, hydrogen gasi inosangana yakanangana nezvigadzirwa, uye zvinodikanwa zvekuchena uye kusachena zvirimo zvakanyanya kuomarara. Semuyenzaniso, muindasitiri yesemiconductor, haidrojeni inoshandiswa kuita senge crystal uye substrate kugadzirira, oxidation, annealing, zvichingodaro, izvo zvine mipimo yakakwirira zvakanyanya pane tsvina yakaita seokisijeni, mvura, heavy hydrocarbons, hydrogen sulfide, nezvimwewo muhydrogen.
2.Nheyo yekushanda ye deoxygenation
Pasi pechiito chekugadzirisa, shoma shoma yeokisijeni muhydrogen inogona kuita nehydrogen kuti ibudise mvura, ichizadzisa chinangwa che deoxygenation. Iyo reaction ndeye exothermic reaction, uye maitiro equation ndeaya anotevera:
2H ₂+O ₂ (catalyst) -2H ₂ O+Q
Nekuti kuumbwa, makemikari zvimiro, uye kunaka kweiyo catalyst pachayo haishanduke isati yasvika uye mushure mekuita, iyo catalyst inogona kushandiswa kuenderera pasina kuvandudzwa.
Iyo deoxidizer ine mukati nekunze cylinder chimiro, ine catalyst inotakurwa pakati pekunze uye mukati macylinders. Iyo inoputika-inopisa yemagetsi inopisa chikamu inoiswa mukati memukati cylinder, uye maviri tembiricha sensors anowanikwa kumusoro uye pasi peiyo catalyst packing kuti ione uye idzore kuita tembiricha. Silinda rekunze rakaputirwa nerutsigiro kudzivirira kurasikirwa nekupisa uye kudzivirira kutsva. Iyo haidrojeni yakasvibirira inopinda muhumburumbira hwemukati kubva kuchipinda chepamusoro che deoxidizer, inopiswa nemagetsi ekupisa chinhu, uye inoyerera nemubhedha inokonzeresa kubva pasi kusvika kumusoro. Okisijeni iri muhaidhirojeni mbishi inopindirana nehaidhirojeni pasi pechiito chechairi kuburitsa mvura. Iyo okisijeni yemukati muhydrogen inoyerera ichibuda kubva pazasi yekubuda inogona kudzikiswa kusvika pazasi 1ppm. Mvura inogadzirwa nemusanganiswa inoyerera ichibva mu deoxidizer mune gasi fomu ine hydrogen gasi, inonamira mune inotevera hydrogen inotonhorera, mafirita mumhepo-yemvura separator, uye inoburitswa kubva muhurongwa.
3.Kushanda musimboti wekuoma
Kuomeswa kwehydrogen gasi kunotora adsorption nzira, uchishandisa ma molecular sieves se adsorbents. Mushure mekuoma, dova rehydrogen gasi rinogona kusvika pazasi -70 ℃. Molecular sieve imhando yealuminosilicate compound ine cubic lattice, iyo inoumba makomba akawanda akaenzana mukati mushure mekupererwa nemvura uye ine nzvimbo yakakura kwazvo. Masefa eMolecular anonzi mamolecular sieves nekuti anogona kupatsanura mamorekuru ane maumbirwo akasiyana, dhayamita, polarities, boiling point, uye saturation level.
Mvura imorekuru wepolar, uye masefa emamorekuru ane hukama hwakasimba hwemvura. Iyo adsorption yemamolecular sieves ndeyekushambadza kwemuviri, uye kana iyo adsorption yazara, inotora nguva yekupisa uye kudzoreredza isati yagona kushambadzwa zvakare. Naizvozvo, angangoita maviri akaomeswa anosanganisirwa mumudziyo wekuchenesa, neimwe ichishanda apo imwe ichigadzira patsva, kuve nechokwadi chekuenderera mberi kwekugadzirwa kwedova rinogadzika gasi rehydrogen.
Iyo yekuomesa ine mukati nekunze cylinder chimiro, ine adsorbent yakatakurwa pakati pekunze uye mukati macylinders. Iyo inoputika-yemagetsi yekudziya yemagetsi inoiswa mukati memukati cylinder, uye maviri tembiricha sensors anowanikwa kumusoro uye pasi pema molecular sieve packing kuti aone uye adzore kudziya kwekuita. Silinda rekunze rakaputirwa nerutsigiro kudzivirira kurasikirwa nekupisa uye kudzivirira kutsva. Kuyerera kwemhepo munharaunda yeadsorption (kusanganisira yekutanga uye yechipiri inoshanda nyika) uye nyika yekuzvarwa patsva inodzoserwa kumashure. Munzvimbo yeadsorption, pombi yepamusoro ndiyo yekubuda kwegasi uye pombi yepasi ndiyo inopinza gasi. Mumamiriro ekuzvarwa patsva, pombi yepamusoro ndiyo inopinza gasi uye pombi yepazasi ndiyo inobuda gasi. Iyo yekuomesa system inogona kukamurwa kuita maviri shongwe dryer uye matatu shongwe dryer zvichienderana nehuwandu hweanoomesa.
4.Two shongwe maitiro
Mavhiri maviri akaiswa mumudziyo, ayo anochinja uye anovandudza mukati mechikamu chimwe chete (maawa makumi mana nemasere) kuti awane kuenderera kwekushanda kwechigadzirwa chose. Mushure mekuoma, dova rehydrogen rinogona kusvika pazasi -60 ℃. Munguva yekushanda kutenderera (48 maawa), dryer A uye B vanopinda kushanda nekuvandudza nyika, zvichiteerana.
Mune imwe switching denderedzwa, iyo yakaoma inosangana nenyika mbiri: kushanda nyika uye yekuzvarwa patsva.
· Regeneration state: Iko kugadzirisa gasi vhoriyamu izere gasi vhoriyamu. Mamiriro ekuzvarwa patsva anosanganisira kupisa nhanho uye kuvhuvhuta kutonhora nhanho;
1) Kupisa nhanho - iyo heater mukati memuomesi inoshanda, uye inomira inomira kupisa kana tembiricha yepamusoro inosvika pakukosha kwakaiswa kana nguva yekudziya inosvika pakukosha kwakaiswa;
2) Kutonhodza nhanho - Mushure mekunge muomesi wamira kupisa, mhepo inoyerera inoramba ichiyerera kuburikidza neyakaomeswa munzira yekutanga kuti itonhodze pasi kusvika iyo yakaoma ichichinja kune inoshanda mode.
· Mamiriro ekushanda: Iyo vhoriyamu yekugadziridza mhepo iri pahuwandu hwakazara, uye hita mukati memuomesi haisi kushanda.
5.Three tower workflow
Parizvino, iyo matatu shongwe process inoshandiswa zvakanyanya. Zvitatu zvinoomesa zvakaiswa mumudziyo, izvo zvine desiccants (molecular sieves) ine yakakura adsorption kugona uye yakanaka tembiricha kuramba. Matatu anoomesa anochinjana pakati pekushanda, kugadzirwa patsva, uye adsorption kuti uwane kuenderera kwekushanda kwechishandiso chose. Mushure mekuoma, dova rehydrogen gasi rinogona kusvika pazasi -70 ℃.
Munguva yekuchinja kutenderera, iyo yakaoma inoenda kuburikidza nematunhu matatu: kushanda, adsorption, uye kuberekwa patsva. Kune imwe neimwe nyika, yekutanga yekuomesera iyo mbishi hydrogen gasi inopinda mushure me deoxygenation, kutonhora, uye kusefa kwemvura inowanikwa:
1) Mamiriro ekushanda: Iro gasi rekugadzirisa gasi rinenge rakazara, iyo heater mukati memuomesi haisi kushanda, uye yepakati imhepo yakasvibirira yehydrogen gasi isina kupera mvura;
Yechipiri dryer inopinda iri pa:
2) Regeneration mamiriro: 20% gasi vhoriyamu: Regeneration mamiriro anosanganisira kupisa nhanho uye kuvhuvhuta kutonhora nhanho;
Kupisa nhanho - iyo heater mukati memuomesi inoshanda, uye inomira inomira kupisa kana tembiricha yepamusoro inosvika pakukosha kwakaiswa kana nguva yekudziya inosvika pakukosha kwakaiswa;
Kutonhodza nhanho - Mushure mekunge muomesi wamira kupisa, mhepo inoyerera inoramba ichiyerera kuburikidza neyakaomeswa munzira yekutanga kuti itonhodze pasi kusvika iyo yakaoma ichichinja kune inoshanda mode; Kana iyo yekuomesa iri mudanho rekuzvarwa patsva, iyo yepakati inoshaya mvura yakaoma hydrogen gasi;
Yechitatu dryer inopinda iri pa:
3) Adsorption state: Kugadzira gasi vhoriyamu i20%, iyo heater muomesa haisi kushanda, uye yepakati ihydrogen gasi rekuzvarwa patsva.
