Summary: Uma ikhonkatha isetshenziselwa ukukhipha i-sulfur emgodini wombani, yiziphi izimfuneko zokugayiwa kwekholotheni? Ukuze sikhethe uhlobo luni lwe-mill yokugayiwa...?
Limestone is one of the most versatile materials which are rich in resources. It is widely used in both industry and construction. Here we’re gonna talk about the most common uses of limestone—desulfurization in power plants. When limestone is used to desulfurize power plants, what are the requirements for limestone grinding? What kind of umshini wokuhlobisa Ingabe kufanele sikhethe? Lapha sizokwethula kini.
1. Izidingo zesibhidi somkhanda lapho sisetshenziswa khona ukususa i-sulfur esizini zezendlini zikagesi
Generally, not all limestone flour can be used for desulfurization. Limestone flour for desulfurization requires not only powder fineness but also calcium carbonate content. In addition, there are also regulations on environmental protection during the grinding production. In order to ensure the comprehensive utilization of desulfurized gypsum and reduce the discharge of sewage, the content of calcium carbonate in the limestone should be higher than 90% when it’s used for desulfurization.
Isipiliyoni esedlule sikhombisa ukuthi ubukhulu be-fineness ye-limestone flour (ebhekwa njengegobolondo eliwusizo ekususeni ugwayi) ezitshalweni zamandla ngokuvamile kudingeka ukuthi bube phakathi kwezinkanyezi eziyi-200 no-325. Ngakho-ke, kudingeka ukuthi usayizi wokuphuma kwegrind mill uhlangabezane nezinga. Kwi-boilers ezishisa amathambo ngemali ephansi enikezwe igesi, ubukhulu be-limestone flour kufanele baqinisekise ukuthi amaphesenti angama-90 adlula ku-sieve engu-250-mesh. Uma utshisa ugwayi onothuli oluningi lwe-sulfur, ubukhulu be-limestone flour kufanele baqinisekise ukuthi amaphesenti angama-90 adlula ku-sieve engu-325-mesh. Ngokuqinisekile, ungasebenzisa futhi i-quicklime (Ubuningi be-lime kufanele bube ngaphezu kwe-85%) njengesithako sokumunca.
2. Yikuphi isigcwalisi somilingo esikufanele sikhethe?
Manje njengoba sesifunde mayelana nesilinganiso sobuciko bokugaya itshe le-limestone, sesinokweqophelo elifanele lokuya kulomshini wokugaywa. Lapha sincoma imishini emibili yokugaya itshe le-limestone ngokuya kulokho okuduma emakethe.
1) Isigcwalisi somilingo se-MTW European Trapezium (Uhlobo olukhulu lwesiI-Raymond Mill)
I-MTW New-type I-Raymond Mill isebenzisa idivayisi yokuvala ekhethekile engavimbeli ukusakaza uphondo, ihlangabezana nosayizi ofunayo futhi iqinisekisa ulawulo olusebenzayo kwekhwalithi yomkhiqizo ophelile. Ngaphezu kwalokho, i-MTW New-type Raymond mill ibe nezixhobo zokukhishwa kwezikhutha ezifanele ezikwazi ukufeza ukusebenza kahle kokukhipha uthuli nokunciphisa ukungcola okuphuma emvelweni. Ngakho-ke kuyasiza ukuhlangabezana nezimfuneko zemvelo. Imishini isebenzisa uhlelo lokudlulisa oluphelele lwe-bevel gear, okwenza isakhiwo sawo sibe sincane futhi sibe nokusebenza okuningi.
2) I-LM Series Vertical Mill
I-LM vertical mill ihlanganisa ukucwiliswa, ukuomisa, ukugaya, ukukhetha amafutha, ukudlulisa konke kwelinye. Umsebenzi wokusebenza ungenziwa ngesinyathelo esisodwa okuholela ekunciphiseni kakhulu imali engenayo. Izinto zingalala emhlonyeni isikhashana, okunciphisa ukukhunjulwa kokuqhuma; ukuxhumana kwezinto eziqukethwe kungalawulwa kangcono futhi. Ngakho, ukukhulu kwemveliso yokugcina kuqinile kakhulu. Ngesikhathi esifanayo, akukho ukuxhumana okungqongqo phakathi kwe-grinding roller kanye ne-grinder table, okuqinisekisa ukuhlanzekile kwamanzi e-limestone (izinto ezincane ze-iron), futhi lokhu kungafanela izidingo.
Iphilisi le-limestone elenziwa nge-umshini wokuhlobisa ye-I-SBM selisetshisiwe ekususa i-sulfur yamahlathi wamandla ahlukahlukene kakhulu, futhi amakhasimende asephumelele ngokuzuzisa kwezomnotho okuhle. Ukuze kungafani i-limestone flour, singakunikeza izincomo ezahlukene nemishini ye-grinding ehambisana nayo.
Uma unemibuzo mayelana namanani ezindawo ezihlukahlukene zokugaya, sicela uxhumane nathi ku-inthanethi noma ushiye umyalezo wakho efomini. Sizokuphendula ochwepheshe!
