A cikin babban hoton samar da masana'antu, akwai wasu ƙananan abubuwa da ke aiki a ɓoye cikin sirri. Bututun cire sulfurization na silicon carbide wani "jarumi ne a bayan fage" - yana ɓuya a cikin hasumiyar cire sulfurization na masana'antun wutar lantarki da masana'antun ƙarfe, kowace rana yana "tsaftace" iskar gas ta masana'antu, yana katse sulfur dioxide mai cutarwa kafin fitar da hayaki. Menene fasalin wannan na'urar da aka yi da kayan silicon carbide?
1, Me yasa ake amfani da silicon carbide? 'Kasusuwa masu tauri' a cikin kayan
Don fahimtar fa'idodinbututun ƙarfe na silicon carbide, muna buƙatar farawa da "tsarin mulkinsu". Silicon carbide wani abu ne da ba na halitta ba wanda aka haɗa shi ta hanyar wucin gadi, tare da ƙwayoyin halitta da aka haɗa ta hanyar haɗin covalent mai ƙarfi don samar da tsari mai ƙarfi kamar lu'u-lu'u. Wannan tsari yana ba shi "masu iko" guda uku:
Mai jure wa tsatsa: Iskar gas ta masana'antu tana gauraya da abubuwa masu lalata kamar su acid mist da limestone slurry, kuma bututun ƙarfe na yau da kullun za su lalace kuma su cika da ramuka. Silicon carbide yana da juriya ga acid da alkali fiye da ƙarfe, kuma yana iya kiyaye daidaiton tsarin koda bayan an daɗe ana nutsewa a cikin yanayi mai tsananin tsatsa.
Yana iya jure yanayin zafi mai yawa: Zafin iskar gas da ke cikin hasumiyar cire sulfurization sau da yawa yakan kai ɗaruruwan digiri Celsius, kuma wani lokacin akwai bambance-bambancen zafin jiki mai tsanani saboda fara aiki da kashe kayan aiki. Daidaiton zafin silicon carbide yana da ƙarfi sosai, kuma ba shi da sauƙi a fashe ko da a lokacin da aka sami mummunan tasirin zafin jiki nan take. Har yanzu abin dogaro ne a ƙarƙashin yanayin zafi mai tsanani.
Yana iya jure lalacewa da tsagewa: Lokacin da slurry mai saurin gudu na desulfurization ya ratsa bututun, zai ci gaba da lalata bangon ciki. Taurin silicon carbide ya fi lu'u-lu'u, kuma yana iya jure wannan irin lalacewa cikin sauƙi. Tsawon lokacin aikinsa ya ninka na bututun filastik ko ƙarfe na yau da kullun sau da yawa.
2, Ba wai kawai 'mai ɗorewa' ba, har ma da 'ƙarfafawa' don ingancin desulfurization
Darajar bututun silicon carbide desulfurization ya wuce "tsawon lokaci". Tsarinsa yana ɓoye wani asiri: hanyoyin juyawa na ciki suna ba da damar slurry desulfurization ya ci gaba da haɗuwa da haɗuwa a cikin kwararar, a ƙarshe yana haifar da ɗigon ruwa mai kyau da iri ɗaya - girman yankin hulɗa tsakanin waɗannan ɗigon ruwa da iskar gas mai ƙarfi, mafi girman ingancin shaƙar sulfur dioxide.
Mafi mahimmanci, ba ya toshewa cikin sauƙi. Ƙananan ƙwayoyin cuta ba makawa suna haɗuwa cikin slurries na masana'antu, kuma kunkuntar hanyoyin bututun ruwa na yau da kullun suna toshewa cikin sauƙi, wanda ke haifar da feshi mara daidaituwa da rage ingancin desulfurization. Tsarin hanyar kwararar bututun silicon carbide yana da faɗi, yana ba da damar ƙwayoyin su wuce cikin sauƙi, yana rage lokacin aiki da kulawa da toshewar ke haifarwa.
3, 'Zaɓi mai mahimmanci' a ƙarƙashin manufofin kare muhalli
Tare da ƙara tsauraran ƙa'idojin muhalli, kamfanoni suna da buƙatu mafi girma don kayan aikin cire sulfur. Misali, an ƙara tsaurara iyakar yawan sulfur dioxide a cikin iskar gas da tashoshin wutar lantarki ke fitarwa. Wannan yana nufin cewa tsarin cire sulfur dole ne ya fi inganci da kwanciyar hankali - kuma aikin bututun bututun kai tsaye yana shafar tasirin tsarkakewa na ƙarshe.
Duk da cewa farashin farko na siyan bututun silicon carbide desulfurization ya fi na bututun silicon carbide na yau da kullun, a zahiri sun fi araha a cikin dogon lokaci. Rayuwar sabis ɗinsa ta ninka ta bututun filastik sau da yawa, wanda zai iya rage yawan maye gurbin da asarar lokacin aiki. Ga kamfanoni masu neman samar da kayayyaki mai ɗorewa, halayyar "zuba jari sau ɗaya, ba tare da damuwa ba na dogon lokaci" tana da matuƙar muhimmanci.
4, Ba wai kawai rage yawan sinadarin sulfur ba, aikace-aikace na gaba za a iya gani
Baya ga maganin iskar gas ta masana'antu, yuwuwar kayan silicon carbide yana bayyana a fannoni da yawa. Juriyar zafinsa mai yawa da juriyar radiation sun sa ya shahara a fannoni masu inganci kamar makamashin nukiliya da sararin samaniya; A cikin sabuwar masana'antar makamashi, ana kuma amfani da shi a cikin kayan aikin tace sintering mai zafi don kayan batirin lithium. A matsayin bututun cire sulfur, har yanzu yana da mahimmanci a cikin tsarin kula da muhalli na yanzu.
Wannan ƙaramin abu da aka ɓoye a cikin hasumiyar cire sinadarin sulfur a zahiri gada ce tsakanin wayewar masana'antu da kariyar muhalli. Yana amfani da hikimar kimiyyar kayan aiki don ba da damar samar da masana'antu su kasance tare da sararin samaniya mai shuɗi da gajimare fari - wataƙila mafi kyawun fassarar fasaha da ke kare muhalli.
