Ulwakhiwo lwe-spherical digester
I-spherical digester yenziwe ikakhulu ngeqokobhe eliyi-spherical, intloko ye-shaft, i-bearing, isixhobo sokudlulisa kunye nombhobho wokudibanisa. I-Digester shell yisitya soxinzelelo esibhityileyo esinodonga olubhityileyo esineepleyiti zentsimbi ze-boiler ezidityanisiweyo. Amandla aphezulu esakhiwo se-welding anciphisa ubunzima bezixhobo, xa kuthelekiswa nesakhiwo se-riveting sinokunciphisa malunga ne-20% yeepleyiti zentsimbi, okwangoku zonke ii-spherical digester zamkela isakhiwo sokusebenzisa. Uxinzelelo oluphezulu oluyilwe kwi-spherical digester yi-7.85 × 105Pa, kwinkqubo yokupheka i-sulfur, i-spherical digester corrosion allowance ingaba yi-5 ~ 7mm. Umngxuma o-oval we-600 x 900mm ubukhulu uvulwa kumgca othe nkqo weqokobhe eliyi-spherical ukuze kulayishwe izinto, kuhanjiswe ulwelo kwaye kugcinwe. Ukuze kuqinisekiswe ukhuseleko lwe-spherical digester, isangqa seepleyiti zentsimbi eziqinisiweyo zijikelezwe kuvuleko oluyi-oval. Indawo yokulayisha ifakwe isigqubuthelo sebhola, emva kokulayisha izinto iya kubotshelelwa nge-bolt ngaphakathi. Kwizinto ezikrwada ezinefayibha ende, ukuvulwa kokulayisha kukwayindawo yokukhupha. I-spherical shell ngaphakathi ifakwe ityhubhu enemingxuma emininzi yokwandisa indawo yokusasazwa komphunga, okuqinisekisa ukupheka ngokulinganayo kwezinto ezikrwada. Ukunciphisa ukungqubana phakathi kodaka kunye nodonga lwangaphakathi, i-sphere iqhagamshelwe ngeentloko ezimbini ze-shaft ezingenanto zentsimbi ephothiweyo nge-flange kwaye ixhaswe kwi-oil ring bearing evulekileyo kancinci, enamathele kwi-concrete stand. Elinye icala lentloko ye-shaft liqhagamshelwe ngombhobho wokungena ngomphunga kwaye elinye icala lentloko ye-shaft liqhagamshelwe ngombhobho wokukhupha, umbhobho uxhotyiswe nge-valve yokuvala, i-pressure gauge, i-safety valve kunye ne-stop valve. Ukuze kuthintelwe ukulahleka kobushushu ngexesha lokupheka, udonga lwangaphandle lwe-spherical digester ludla ngokugqunywa ngumaleko we-insulation ongama-50-60mm ubukhulu.
Iingenelo ze-spherical digester: izinto ezikrwada kunye ne-ejenti yokupheka zinokuxutywa ngokupheleleyo, uxinzelelo kunye nobushushu be-ejenti yolwelo ziyafana ngakumbi, umlinganiselo wolwelo uphantsi, uxinzelelo lwe-ejenti yolwelo luphezulu, ixesha lokupheka lifutshane kwaye indawo yomphezulu incinci kunembiza yokupheka ethe nkqo enomthamo ofanayo, oko konga intsimbi, umthamo omncinci, isakhiwo esilula, ukusebenza lula, iindleko zokufakela kunye nokugcinwa eziphantsi njl.
