Indlela yendabuko yokulungiselela i-sodium polyphosphate kukunciphisa i-hot phosphoric acid nge-mass fraction ye-75% H3PO4 nge-soda ash suspension ukuze kufunyanwe i-neutralized slurry enomlinganiselo we-Na/P we-5:3, kwaye uyigcine ishushu kwi-70℃ ~ 90℃; uze utshize i-slurry efunyenweyo kwisithando se-polymerization ukuze iphelelwe ngamanzi kubushushu obuphezulu, kwaye uyidibanise kwi-sodium tripolyphosphate malunga ne-400℃. Le ndlela yendabuko ayifuni nje kuphela i-hot phosphoric acid ebiza kakhulu, kodwa ikwasebenzisa amandla amaninzi obushushu; ukongeza, xa ulungisa i-slurry ngokuyinciphisa, kuyimfuneko ukufudumeza nokususa i-CO2, kwaye inkqubo iyinkimbinkimbi. Nangona i-hot phosphoric acid ecociweyo ngeekhemikhali ingasetyenziselwa ukuthatha indawo ye-hot phosphoric acid ukuvelisa i-sodium tripolyphosphate, ngenxa yomxholo ophezulu wesinyithi kwi-wet phosphoric acid, kunzima ukuhlangabezana neemfuno zomgangatho weemveliso ze-sodium tripolyphosphate zangoku, kwaye kunzima ukuhlangabezana neempawu ezichazwe kwimigangatho yesizwe.
Okwangoku, abantu baye bafunda ezinye iinkqubo ezintsha zemveliso ye-sodium tripolyphosphate, ezifana nesicelo selungelo elilodwa lomenzi laseTshayina uNombolo 94110486.9 "Indlela yokwenza i-sodium tripolyphosphate", uNombolo 200310105368.6 "Inkqubo entsha yokwenza i-sodium tripolyphosphate", uNombolo 200410040357.9 "Indlela yokwenza i-sodium tripolyphosphate ngendlela ebanzi emanzi-yomileyo", uNombolo 200510020871.0 "Indlela yokwenza i-sodium tripolyphosphate ngendlela yokubola kabini yetyuwa kaGlauber", u-200810197998.3 "Indlela yokwenza i-sodium tripolyphosphate kunye ne-ammonium chloride evelisa ngokuyila", njl.njl.; nangona ezi zisombululo zobugcisa zineempawu zazo, uninzi lwazo kukutshintsha izinto ezikrwada zokungaguquki.
Indlela yokuvelisa i-sodium tripolyphosphate kusetyenziswa i-crude sodium pyrophosphate
I-sodium pyrophosphate ekrwada kuqala ingena kwitanki yokuhlamba ityuwa ukuze isuse uninzi lwe-sodium chloride, ize ingene kwi-plate kunye ne-frame filter press ukuze ihluzwe ngokuyintloko. Ikhekhe lesihluzo liqulethe isixa esikhulu se-sodium pyrophosphate, kwaye uxinzelelo lobunzima be-sodium chloride lungaphantsi kwe-2.5%. Emva koko, isisombululo sitshiswa ukuya kuma-85°C kwitanki yokunyibilikisa ngomphunga ukuze sixutywe kwaye sinyibilike. I-sodium sulfide yongezwa ngexesha lokunyibilikisa ukususa ii-ion zesinyithi. Izinto ezinganyibilikiyo zizinto ezingcolileyo ezifana ne-copper hydroxide. Ihluzwa kwakhona okwesibini. I-filtrate sisisombululo se-sodium pyrophosphate. I-activated carbon yongezwa kwi-filtrate ukuze isuse ii-pigments, i-phosphoric acid yongezwa ukuze i-acidify kwaye ikhawulezise ukunyibilika, kwaye ekugqibeleni i-alkali engamanzi yongezwa ukulungisa ixabiso le-pH ukuya kwi-7.5-8.5 ukulungiselela ulwelo olucociweyo.
Inxalenye yolwelo olucociweyo isetyenziswa ngokuthe ngqo kwicandelo lokulungiselela ulwelo lwe-sodium tripolyphosphate neutralization, kwaye enye inxalenye yolwelo olucociweyo ipompelwa kwi-DTB crystallizer. Ulwelo olucociweyo kwi-DTB crystallizer lupholiswa kwi-heat exchanger ngepompo yokujikeleza enyanzelekileyo kunye namanzi angama-5°C athunyelwa yi-chiller. Xa ubushushu besisombululo buhla ukuya kwi-15°C, luqiniswa lube yi-flocs kwaye emva koko luthuthwe luye kwitanki ephezulu kwaye lufakwe kwi-centrifuge ukuze kwahlulwe i-centrifugal ukuze kufunyanwe iikristale ze-sodium pyrophosphate. Iikristale ze-sodium pyrophosphate zongezwa kwicandelo lokulungiselela ulwelo lwe-neutralization kwinkqubo yokuvelisa i-sodium tripolyphosphate kwaye zixutywe ne-phosphoric acid kunye ne-liquid caustic soda ukulungiselela ulwelo lwe-neutralization njengezinto eziluhlaza zokuvelisa i-sodium tripolyphosphate. I-brine ekhankanyiweyo apha ngasentla ibuyiselwa ukuhlamba i-sodium pyrophosphate ekrwada; xa umxholo we-sodium chloride kwi-brine ufikelela kumlinganiselo, i-brine ifakwa kwi-buffer tank, kwaye i-brine kwi-buffer tank ifakwa kwi-sodium tripolyphosphate tail gas duct jacket ukuze itshintshise ubushushu ne-tail gas enobushushu obuphezulu. I-brine emva kokutshintshana kobushushu ibuyela kwi-buffer tank ukuze itshizwe.
