Munyika yakakura yekugadzira maindasitiri, zvakawanda zvakakosha hazvigone kushanda pasina rutsigiro rwezvinhu zvinoshanda zvakanyanya. Nhasi, tichaunza zvinhu zvine basa rakakosha mumaindasitiri echinyakare akadai semakilni uye masisitimu ekubvisa sulfurization -zviumbwa zvesimbi zvesilicon carbide.
Chii chinonzi silicon carbide ceramic?
Silicon carbide ceramic ipurasitiki yepamusoro inoumbwa nesilicon nekabhoni. Haisi ceramic yakajairika, asi "metamaterial" ine hunhu hwakawanda hwakanaka. Ine hunhu hwesimba rekupisa kwakanyanya, kuramba kupfeka zvakanaka, kuwedzera kupisa kwakaderera, kuomarara kwakanyanya, uye kuramba ngura kwemakemikari, izvo zvinoita kuti ive yakasiyana nezvimwe zvinhu zvakawanda.
Zvigadzirwa zvesimbi zvesilicon carbide zvinogadzirwa neReaction sintered imhando yakasarudzika yezvigadzirwa zvesilicon carbide, uye maitiro azvo ekugadzirira akasiyana zvikuru - kutanga, zvidimbu zvidiki zvealpha SiC nezvimwe zvinodzvanywa mumuviri wegirini, uye zvobva zvasangana nesilicon yemvura pakupisa kwakanyanya. Panguva ino, kabhoni iri muchinhu chisina chinhu inosangana nemaitiro akanaka emakemikari neSi yakapinda, ichigadzira β - SiC uye ichibatana zvakasimba neα - SiC. Panguva imwe chete, silicon yakasununguka inozadza maburi, pakupedzisira ichiwana zvinhu zveceramic zvakawandisa.
Dombo rekona muchoto
Kupisa kwesimbi yesilicon carbide ceramics ibasa rinokosha uye rinokosha mumakiln akasiyana-siyana anodziya zvakanyanya. Semuenzaniso, mumakiln ekugadzira ceramic akadai semakiln anotenderera, makiln etunnel, makiln eshuttle, nezvimwewo, inogadzirwa kuita zvinhu zvakakosha zvakaita sema nozzle sleeves, ma crossbeam rollers, uye mapaipi emhepo inotonhora.
Chivharo chemurazvo chinogona kudzora tembiricha iri muchoto zvinobudirira. Chine hunhu hwesimba rekupisa kwakanyanya, kuramba oxidation, kuramba kupera, uye kuramba kutonhora nekukurumidza uye kupisa. Hachizoputsika kana kukanganisika mushure mekushandiswa kwenguva refu kwekupisa kwakanyanya, zvichiita kuti tembiricha ive yakagadzikana muchoto. Zvakakosha pakupisa zvigadzirwa zveceramic zvemhando yepamusoro.
Maroller edanda repamusoro nemidziyo yemhepo inotonhora zvine basa rakakosha rekutsigira nekufema. Roller yedanda repamusoro ine hunhu hwekugadzikana kwakanaka kwekupisa, kuramba oxidation, uye kuramba kupisa kwakanyanya. Hazvisi nyore kuchinjika nekukombama mushure mekushandiswa kwenguva refu pakupisa kwakanyanya, zvichiita kuti chimiro chemukati chechoto chigadzikane uye kutakurwa kwezvinhu zvifambe zvakanaka. Door yemhepo inotonhora ine basa rekutonga kuyerera kwegasi uye kupararira kwekupisa mukati mechoto, zvichiita kuti choto chishande zvakanaka.
Kubva pamaonero ezvikamu zvakagadzirwa, reaction sintered silicon carbide ine zvakanakira pachena mukugadzirwa kwezvikamu zvechitofu. Nekuda kwehukuru hwayo husingachinji isati yapiswa uye mushure mekupiswa, inogona kugadziriswa kuita chero chimiro nehukuru mushure mekuumbwa. Vagadziri vekitofu vanogona kugadzirisa maumbirwo akasiyana-siyana uye zvirevo zvezvikamu zvichienderana nemagadzirirwo akasiyana ekitofu uye zvinodiwa pakugadzirwa, zvichizadzisa zvinodiwa zvekugadzirwa kwezvigadzirwa zvakakura uye zvakaoma, izvo zvakaoma kuti zvimwe zvinhu zviwanikwe.
Mutsetse wakasimba wekudzivirira we desulfurization system
Munzvimbo dzekuchengetedza nharaunda dzakadai sekubvisa sulfurization yemagetsi, simbi dzesilicon carbide dzinoitawo basa guru, zvinonyanya kuratidzwa muchikamu chakakosha chemushonga wekubvisa sulfurization. Gasi reflue rinoburitswa kubva mumagetsi rine huwandu hwakawanda hwezvinosvibisa zvakaita sesulfur dioxide, uye mushonga wekubvisa sulfurization zvishandiso zvakakosha pakubvisa zvinosvibisa izvi.
Mushonga wekubvisa sulfurization une simba rakawanda, kuomarara kwakanyanya, kuramba ngura kwakasimba, kuramba kupfeka, uye kuramba kupisa kwakanyanya. Une hupenyu hunoshamisa hwebasa mumamiriro ezvinhu akaoma, izvo zvisingaenzaniswi nezvinhu zvakajairwa. Mhando dzemushonga wekubvisa sulfurization dzinoshandiswa dzinosanganisira spiral nozzles nemavortex nozzles, ane magadzirirwo akasiyana uye misimboti yekushanda, asi anogona kuita atomize desulfurizer zvinobudirira uye kuibata zvizere ne flue gas, nokudaro achiwana desulfurization effect yakanaka.
Kuburikidza nekugadzirwa kwayo kwakasiyana, muromo wespiral unoita kuti mvura iri muchikamu chekunze irove pamusoro pespiral nekona yakati pamuromo wespiral, inochinja nzira yekupfapfaidza yobva pamuromo wespiral, zvichiita nzvimbo yakasimba ine mhute, iyo inogona kupa makona akasiyana-siyana ekupfapfaidza, uye ichiri nekushanda kwakasimba kwekunyudzwa pasi pekumanikidzwa kwakaderera. Mhute yevortex inobvumira slurry kupinda mukamuri rinotenderera remuromo wespiral kubva kudivi rakatenderedza, uye yobva yaburitsa kubva pagomba nekona dzakarurama kuenda kudivi rekupinza. Spray diki uye yakafanana, uye nzira yevortex yakakura, iyo isiri nyore kuivhara.
Kune zvikamu zvakagadzirwa zvema "desulfurization systems", "reaction sintered silicon carbide" inogona kugadzirisa chimiro che "nozzle", saizi, uye hunhu hwekupfapfaidza zvinoenderana nemaitiro akasiyana e "desulfurization", mwero wekuyerera kwegasi remvura, huwandu, nezvimwe zvinhu, zvichiita kuti system ye "desulfurization" ishande zvakanaka uye yakagadzikana uye ichisangana nezvinodiwa zvakanyanya zvezvakatipoteredza.
Zvigadzirwa zvesimbi zvesilicon carbide zvine reaction sintered zvinoita basa guru muminda yemaindasitiri echinyakare akadai semaovheni uye masisitimu ekubvisa sulfurization nekuda kwehunhu hwazvo hwakasiyana uye zvakanakira zvinogona kugadziriswa. Zvinopa vimbiso yakasimba yekushanda zvakanaka, kwakasimba, uye kwakanaka kwekugadzirwa kwemaindasitiri uye zvinopa simba guru mukusimudzira tekinoroji nekusimudzira maindasitiri echinyakare.
