Summary: Marka limestone-ka la isticmaalo si loo saaro sulfur-ka ee warshadaha korontada, waa maxay shuruudaha loogu baahan yahay in limestone-ka la shiido? Noocee ah ayaa ay tahay in mashiinka shiida loo doorto?...
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 dhulkii kala-wareega Ma inaad doorano? Halkan waxaan idiin soo bandhigaynaa:
1. Shuruudaha dhulka dhulka loo isticmaalo marka loo isticmaalo nadiifinta qiiqa warshadaha korontada
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.
Khibradda hore waxay muujineysaa in dhumucda burinta limestone-ka (loo isticmaalo desulfurization) ee warshadaha korontada guud ahaan loo baahan yahay inay tahay mid u dhaxaysa 200 ilaa 325 mesh. Marka waxay u baahan tahay in cabbirka wax-soo-saarka mashiinka dhagax-burinta uu buuxiyo heerka. Warshadaha kuleeylka leh gaas yar oo sulfur ah ee shidaalka, dhumucda burinta limestone waa inay xaqiijisaa heerka dhaafitaanka ah 90% oo dhex mara shaandhada 250-mesh. Marka shidaalka sulfur-ka badan la shido, dhumucda burinta limestone waa inay xaqiijisaa heerka dhaafitaanka ah 90% oo dhex mara shaandhada 325-mesh. Dabcan, sidoo kale waxaad isticmaali kartaa kalkaynta degdegga ah (nadiifnimada kalkaynta waa inay ka sarreeysa 85%) sida nuugo.
2. Maxaa nooca burburka la dooranaya?
Hadda oo aan baranay heerka saxnaanta dhagaxa limestone-ka, waxaan haynaa tixraac ku habboon oo ku saabsan doorashada mashiinka mindida saxda ah. Halkan waxaan ku talinaynaa 2 mashiin oo lagu shiido limestone iyadoo loo eegayo caan ahaanshaha suuqa.
1) Burburka Dhagaxa Yurub ee MTW (Nooc cusub oo horumaray oo ka mid ah burburka Raymond)
MTW Nooca Cusub ee Dhismaha Raymond wuxuu qaataa qalab xirida gaar ah oo ka hortagi kara dayaca xidhmada, kordhinta fineness looga baahan yahay iyo xaqiijinta kontorool wax ku ool ah ee tayada wax soo saarka dhameystiran. Intaas waxaa sii dheer, Dhismaha Raymond nooca cusub ee MTW waxaa lagu qalabeeyey qalabka ka-saarista boorka xirfadlayaasha ah kaas oo xaqiijin kara waxtarka sare ee ka-saarista boorka iyo hoos u dhigista fiiqa sii deyneysa. Sidaas darteed, waa mid ka faa'iideysanaya in la buuxiyo shuruudaha deegaanka. Qalabku wuxuu qaataa gudbinta dhammaystiran ee taarikada, taas oo ka dhigaysa qaab dhismeedkeeda mid ka weyn oo dabacsan.
LM Taxanaha Goob-toosaha
LM-ka mashiinka dhufaysha ee toosan wuxuu isku daraa burburinta, qalajiinta, shiidista, kala soocidda budada, iyo gaadiidka hal qalab. Habka shaqada waxaa lagu sameyn karaa tallaabo keliya taasoo si weyn u dhimi karta maalgelinta. Maaddooyinka waxay ku sii jiri karaan mashiinka muddo gaaban, taasoo dhimi karta dib u celinta shiidista; isku-darka kiimikada sidoo kale waxaa lagu xakameyn karaa si fiican. Sidaa darteed, tayada alaabta dhammaatay waa mid deggan. Isla mar ahaantaana, ma jiraan isku-taabashada tooska ah ee u dhaxeysa dhiirta shiidista iyo miiska shiidista, taasoo hubinaysa nadiifnimada burka dhagaxa (heer hoose oo bir ah), taasoo buuxinaysa shuruudaha warshadaha korontada ee dhexgalinta sulfuric acid.
Qalabka burburinta limestone-ka ee uu soosaaro mashiinka SBM wuxuu si wanaagsan loogu adeegsan jiray nadiifinta sulfur-ka ee warshado koronto oo kala duwan, macaamiishuna waxay gaareen faa'iidooyin dhaqaale oo wanaagsan. Wixii burburin limestone ah oo kala duwan, waxaan ku siin karnaa xalal kala duwan iyo qalab burburin ku habboon.
Haddii aad qabtid su'aalo ku saabsan qiimaha qalliinada kala duwan, fadlan nagu soo xiriir khadka tooska ah ama ka tag fariintaada foomka. Waxaan kuu haynaa jawaab xirfadle ah!
