Tag nrho cov qauv ntawm lubnitrogen hluav taws xob rhaubyuav tsum tau tsim los ua ke nrog rau qhov teeb meem ntawm kev teeb tsa, kev ntsuas siab, thiab cov qauv kev nyab xeeb, nrog rau qhov tshwj xeeb ntawm plaub lub ntsiab lus hauv qab no:
1. Cov qauv siab-cov kabmob: Sib tw lub zog siab
Plhaub khoom: Raws li los yog siab tshaj qhovlub raj cua sovcov khoom siv (xws li, seamless stainless hlau yeeb nkab rau cov xwm txheej siab, phab ntsa tuab yuav tsum raug xam raws li GB / T 150, nrog rau kev nyab xeeb ntawm 1.2 ~ 1.5);
Txoj kev sib khi: Rau qhov tsis tshua muaj siab (≤1MPa), siv flange gasket sealing (gasket cov khoom xaiv xws li roj-resistant asbestos lossis fluororubber); rau kev kub siab (≥2MPa), ntiav vuam sealing los yog siab-siab flanges (xws li tus nplaig-thiab-groove flanges) los tiv thaiv nitrogen to (nitrogen toodorless thiab tuaj yeem yooj yim ua rau hauv zos tsis muaj oxygen).
2. Dej Channel Tsim: Xyuas kom muaj cua sov
Flow channel txoj kab uas hla: Yuav tsum phim lub raj xa dej nitrogen kom tsis txhob dhau "txo txoj kab uas hla" ua rau cov dej ntws hauv zos siab tshaj (tseem ceeb poob) lossis qis dhau qis tshaj tawm (tsawg cua sov). Feem ntau, qhov inlet thiab qhov hluav taws xob yeeb nkab diameters ntawmlub tshuab cua sovyuav tsum phim cov kav raj xa dej los yog ib qho loj dua;
Internal flow diversion: Lojcua sovxav tau tus tsim ntawm "dav diversion daim hlau" los coj cov roj nitrogen sib npaug los ntawmcov hlab cua sov,tiv thaiv "short circuits" (qhov twg qee qhov nitrogen hla ntawm thaj chaw cua sov ncaj qha, ua rau muaj kev hloov pauv hauv qhov hluav taws xob kub).
3. Rwb thaiv tsev tsim: Txo kev siv hluav taws xob thiab tiv thaiv kev kub nyhiab
Cov khoom siv rwb thaiv tsev: Xaiv cov ntaub ntawv uas muaj qhov kub thiab txias tsis muaj thermal conductivity, xws li txhuas silicate wool (heat-resistant ≥800 ° C). Lub rwb thaiv tsev txheej thickness feem ntau yog li ntawm 50 mus rau 200mm (xws li ambient thiab qhov hluav taws xob kub los xyuas kom meej lub plhaub sab nraud kub ≤50 ° C, tsis txhob siv hluav taws xob pov tseg thiab cov neeg ua haujlwm kub hnyiab);
Plhaub Khoom: Cov txheej txheem txheej txheej ntawm cov rwb thaiv tsev yuav tsum tau qhwv nrog lub plhaub stainless hlau (cov khoom siv carbon steel / 304) txhawm rau txhim kho kev tiv thaiv thiab tiv thaiv cov khoom siv rwb thaiv tsev kom tsis txhob ntub los yog puas.
