Ulwakhiwo lulonke lwenitrogen heater yombanemayiyilwe ngokubambisana nemeko yofakelo, umlinganiselo woxinzelelo, kunye nemigangatho yokhuseleko, kugxininiswe ngakumbi kwezi ngongoma zine zilandelayo:
1. Isakhiwo soxinzelelo: Uhambelana noxinzelelo lwenkqubo
Impahla yeqokobhe: Iyahambelana okanye ingaphezulu kuneityhubhu yokufudumezaizinto eziphathekayo (umzekelo, umbhobho wensimbi engenamthungo kwiimeko zoxinzelelo oluphezulu, ubukhulu bodonga kufuneka bubalwe ngokwe-GB / T 150, kunye nokhuseleko lwe-1.2 ~ 1.5);
Indlela yokutywina: Uxinzelelo oluphantsi (≤1MPa), sebenzisa ukutywinwa kwe-gasket ye-flange (izinto ezikhethiweyo ze-gasket ziquka i-asbestos engamelana neoli okanye i-fluororubber); kuxinzelelo oluphezulu (≥2MPa), sebenzisa ukutywinwa kwe-welding okanye i-high-pressure flanges (ezifana ne-language-and-groove flanges) ukuthintela ukuvuza kwe-nitrogen (ukuvuza kwe-nitrogen akunavumba kwaye kunokukhokelela ngokulula ekunqongopheni kweoksijini yendawo).
2. Uyilo lweSitishi se-Fluid: Qinisekisa nokuba Ukufudumala
Idayamitha yomjelo ohambayo: Kufuneka ihambelane nedayamitha yombhobho wenitrogen ukunqanda "ukuncipha kwedayamitha" ngokugqithisileyo okubangela ukuba isantya sokuqukuqela sasekhaya siphezulu ngokugqithisileyo (ilahleko enkulu yoxinzelelo) okanye isantya sokuhamba esisezantsi ngokugqithisileyo (ukufudumeza okungalinganiyo). Ngokuqhelekileyo, i-inlet kunye ne-outlet ipayipi ye-diameters yeihithakufuneka ingqinelane nombhobho wendlela okanye ibe yisayizi enye enkulu;
Uphambuko lokuhamba kwangaphakathi: Kukhuluizifudumezizifuna uyilo lwe "flow diversion plates" ukukhokela igesi yenitrogen ngokulinganayoiityhubhu zokufudumeza,ukuthintela "iisekethe ezimfutshane" (apho initrogen ethile idlula ummandla wokufudumeza ngokuthe ngqo, ibangele ukuguquguquka kwiqondo lobushushu lokuphuma).
3. Uyilo lwe-Insulation: Ukunciphisa ukusetyenziswa kwamandla kunye nokuthintela ukutshisa
I-Insulation Material: Khetha izinto ezinokumelana nobushushu obuphezulu kunye ne-thermal conductivity ephantsi, njenge-aluminium silicate wool (i-heat-resistant ≥800 ° C). Ubukhulu be-insulation layer ngokuqhelekileyo buqala ukusuka kwi-50 ukuya kwi-200mm (kubalwa ngokusekelwe kumaqondo obushushu angaphandle kunye ne-outlet ukuqinisekisa ubushushu bangaphandle beqokobhe ≤50 ° C, ukuphepha inkcitho yamandla kunye nokutsha kwabasebenzi);
I-Shell Material: Umaleko wangaphandle we-insulation kufuneka uhlanganiswe ngegobolondo lensimbi engenasici (i-carbon steel / 304 impahla) ukunyusa ukhuseleko kunye nokukhusela izinto zokugquma ukuba zingabi manzi okanye zonakaliswe.
