I-Nernst 1735 acid dew point analyzer esandula kuphehlelelwa sisixhobo esikhethekileyo esinokulinganisa iqondo lobushushu be-asidi kwi-gas flue yebhoyila kunye neziko lokufudumeza kwi-intanethi ngexesha lokwenyani. Iqondo lobushushu acid iqondo lombethe elinganiswe isixhobo unako ukulawula ngokufanelekileyo irhasi ubushushu bompompo kwiibhoyila kunye neziko zokufudumeza, ukunciphisa izixhobo ubushushu obuphantsi sulfuric acid indawo umhlwa umhlwa, ukuphucula ukusebenza kakuhle thermal, ukwandisa ukhuseleko kwibhoyila yokusebenza kunye nokwandisa ubomi izixhobo.
Emva kokusebenzisa i-Nernst 1735 acid dew point analyzer, unokwazi ngokuchanekileyo i-acid dew point value kwi-flue gas yeebhoyila kunye neziko lokufudumeza, kunye nomxholo we-oksijini, umphunga wamanzi (% ixabiso lomphunga wamanzi) okanye ixabiso lombethe kunye nomxholo wamanzi ( G grams/KG ngekhilogram) kunye nexabiso lokufuma iRH. Umsebenzisi unokulawula ubushushu begesi yokukhupha ngaphakathi kuluhlu oluthile oluphezulu kancinci kunendawo yombethe ye-asidi yerhasi yeflue ngokubonisa isixhobo okanye imiqondiso emibini yemveliso ye-4-20mA, ukuze kuthintelwe ukubola kwe-asidi ephantsi kunye nokwandisa ukhuseleko lokusebenza kwibhoyila.
Kwiibhoyila zoshishino okanye iibhoyili zezityalo zamandla, ukucocwa kwepetroleum kunye namashishini amachiza kunye neziko lokufudumeza. Amafutha efosili (irhasi yendalo, irhasi eyomileyo yokucoca, amalahle, ioli enzima, njl.njl.) asetyenziswa ngokubanzi njengamafutha.
La mafutha aqulethe ngaphezulu okanye ngaphantsi komlinganiselo othile wesulfure, eya kuvelisa i-SO2kwinkqubo yokutshiswa kweperoxide. Ngenxa yobukho be-oksijini engaphezulu kwigumbi lokutsha, inani elincinci le-SO2ngakumbi idibanisa neoksijini ukwenza iSO3, Fe2O3kunye neV2O5phantsi kweemeko zomoya ezigqithisileyo eziqhelekileyo. (i-flue gas kunye nentsimbi evuthayo iqulethe le nxalenye).
Malunga ne-1 ~ 3% yazo zonke ii-SO2iguqulelwa kwi-SO3. SO3Irhasi kwirhasi yobushushu obuphezulu ayidli ntsimbi, kodwa xa ubushushu berhasi yeflue yehla ngaphantsi kwe400°C, SO.3iya kudibanisa nomphunga wamanzi ukuvelisa umphunga we-asidi ye-sulfuric.
Ifomula yokusabela imi ngolu hlobo lulandelayo:
SO3+ H2O ——— H2SO4
Xa umphunga we-sulfuric acid ujiya kumphezulu wokufudumeza emsileni weziko, ubushushu obuphantsi be-sulfuric acid umphunga uya kwenzeka.
Kwangaxeshanye, ulwelo lwe-asidi ye-sulfuric edityanisiweyo kwindawo yobushushu obuphantsi bobushushu nayo iya kubambelela eluthulini lwerhasi ye-flue ukwenza uthuthu oluncangathi ekungekho lula ukulususa. Umjelo wegesi we-flue uvaliwe okanye uvalwe, kwaye ukuchasana kuyanda, ukuze kwandiswe ukusetyenziswa kwamandla okwenziwa kwedrafti fan. Umhlwa kunye nokuvaleka kothuthu kuya kubeka emngciphekweni imeko yokusebenza yendawo yokufudumeza kwibhoyila. Ekubeni i-flue gas iqulethe zombini i-SO3kunye nomphunga wamanzi, ziya kuvelisa i-H2SO4Umphunga, okhokelela ekwandeni kwendawo yombethe eneasidi yegesi yombane. Xa iqondo lobushushu lerhasi ye-flue lingaphantsi kune-asidi yombethe weqondo lobushushu legesi ye-flue, i-H2SO4umphunga uya kubambelela kwiflue kunye nesitshintshi sobushushu ukwenza i-H2SO4isisombululo. Ngaphezu koko, yonakalisa izixhobo, okukhokelela ekuvuzeni kokutshintsha ubushushu kunye nomonakalo weflue.
Kwizixhobo ezixhasayo zesithando sokufudumala okanye ibhoyili, ukusetyenziswa kwamandla e-flue kunye ne-heat exchanger akhawunti malunga ne-50% yokusetyenziswa kwamandla onke kwesixhobo. Ukushisa kwegesi yokushisa kuchaphazela ukusebenza kakuhle kwe-thermal yokufudumeza iziko kunye neebhoyili. Ukuphakama kweqondo lokushisa lokukhupha, ukuthoba ukusebenza kwe-thermal. Ngalo lonke i-10 ° C ukunyuka kweqondo lokushisa kwegesi yokukhupha, ukusebenza kakuhle kwe-thermal kuya kuncipha malunga ne-1%. Ukuba ubushushu berhasi yokukhupha bungaphantsi kunobushushu bombethe we-asidi yerhasi ye-flue, iya kubangela ukubola kwezixhobo kwaye ibangele iingozi zokhuseleko ekusebenzeni kweziko lokufudumeza kunye neebhoyila.
Ubushushu obufanelekileyo bokukhupha kwiziko lokufudumeza kunye nebhoyila kufuneka bube phezulu kancinci kunobushushu bendawo yeasidi yombethe werhasi yombane. Ke ngoko, ukugqiba iqondo lobushushu bobushushu be-asidi kwiziko lokufudumeza kunye neebhoyila sisitshixo sokuphucula ukusebenza kakuhle kwe-thermal kunye nokunciphisa iingozi zokhuseleko lokusebenza.
