I-Silicon carbide exchanger heat: isisombululo esisebenzayo sokulawula i-thermal kwiindawo ezingqongileyo

Kwintsimi yoshishino apho amaqondo okushisa aphezulu, i-corrosive media, kunye neemeko zokusebenza ezigqithisileyo zihlala zisenzeka, izinto zemveli zihlala zingonelanga. Njengenkokeli yokusabela kwitekhnoloji ye-silicon carbide ceramic yokusabela, siyayazi kakuhle indlela le mathiriyeli yotshintsho eyichaza ngokutsha imida yetekhnoloji yokutshintshiselana ngobushushu. Eli nqaku liza kukuthatha ukuba uqonde ukuba kuthenii-silicon carbide abatshintshi bobushushubaye baba ngabo “bonke” kwiindawo ezirhangqileyo.
Izinto ezine eziluncedo zeSilicon Carbide
I-Silicon carbide (i-SiC) yimathiriyeli ye-ceramic ephuculweyo eyenziwe ngobuchule, kwaye indibaniselwano yayo eyodwa yeepropathi iyenza ibe lolona khetho lufanelekileyo kwisixhobo sokutshintshiselana ngobushushu phantsi kweemeko zokusebenza ezigqithisileyo.
1. Ukuqhuba kakuhle kwe-thermal
Ukusebenza kwe-thermal conductivity ye-silicon carbide idlula kwizinto zetsimbi ezifana nentsimbi engenasici, kwaye inokudlulisa ngokukhawuleza ubushushu kwiimeko zobushushu obuphezulu, iphucula kakhulu ukusetyenziswa kwamandla ngelixa inciphisa umthamo wezixhobo.
2. Ukungoyiki amaqondo obushushu agqithisileyo
Izixhobo zetsimbi zithande ukuthamba kunye nokuguquka phantsi kobushushu obuphezulu obuzinzileyo, ngelixa i-silicon carbide inokugcina uzinzo lwesakhiwo kwindawo engaphezulu kwe-1350 ° C, iyenza iqabane elithembekileyo lexesha elide lezixhobo ezinjengeekhilni zobushushu obuphezulu kunye ne-reactors yekhemikhali.

3. Ingcali yendalo yokumelana nokubola
Nokuba kwimithombo yeendaba eyonakalisayo efana ne-asidi eyomeleleyo okanye imeko-bume yetyuwa ephezulu, umaleko okhuselweyo we-oxide uya kuzenzela ngokuzenzekelayo kumphezulu we-silicon carbide ukuthintela ukhukuliseko lweekhemikhali kunye nokunciphisa kakhulu ukugcinwa rhoqo.
Undoqo wokusabela sintering inkqubo
Itekhnoloji yethu engundoqo, i-reaction sintered silicon carbide (RBSC), yenza imidibaniso exineneyo kunye neyunifomu ye-ceramic ngokufaka izinto zesilicon kwi-porous carbon matrix. Le mpumelelo yetekhnoloji izisa iingenelo ezintathu eziphambili:
-Nciphisa amanqaku abuthathaka abangelwa yi-pores yangaphakathi kwizinto zendabuko ze-sintered
-Ukuvelisa ngokuchanekileyo uyilo lwejelo lokuqukuqela elintsonkothileyo ukuphucula ukusebenza kakuhle kokugqithisela ubushushu
-Ukulinganisa ukusebenza okuphezulu kunye nokulawulwa kweendleko
Uzinzo lwexesha elide, ukuncitshiswa kweendleko kuwo wonke umjikelo wobomi
Ukutshintshwa rhoqo kwezinto zokutshintshiselana kobushushu besinyithi ngenxa yokubola kunye nokunyuka kube yimbali. Ukomelela okungokwemvelo kwezixhobo ze-silicon carbide kwenza ukuba ube namava okusebenza asimahla ngexesha lofakelo, ngokuqhubekayo udala ixabiso kuwo wonke umjikelo wobomi besixhobo.
Njengomntu osungula izinto ezintsha ogxile ekuphenduleni i-silicon carbide ngaphezulu kweminyaka engama-20,Shandong Zhongpengibisoloko izibophelele ekuboneleleni izisombululo zolawulo lwe-thermal ezilungiselelwe abathengi. Nokuba ufuna ukubuyisela izixhobo esele zikho okanye uphuhlise izixhobo ezitsha, iqela lethu liya kukunceda ukuba ukhulule amandla apheleleyo ezinto zesilicon carbide.
