Isingeniso ku-phosphogypsum
I-Phosphogypsum ibhekisela kudoti oqinile ekukhiqizweni kwe-phosphoric acid nge-sulfuric acid phosphate rock, ingxenye eyinhloko yi-calcium sulfate. I-Phosphorus gypsum ngokuvamile iyimpuphu, ukubukeka kumpunga, kuphuzi okumpunga, kuluhlaza okotshani okukhanyayo neminye imibala, iqukethe i-phosphorus ephilayo, ama-sulfur compounds, ubukhulu obukhulu bungu-0.733-0.88g/cm3, ububanzi bezinhlayiya ngokuvamile bungu-5 ~ 15um, ingxenye eyinhloko yi-calcium sulfate dihydrate, okuqukethwe kubalwa cishe ngo-70 ~ 90%, phakathi kwazo izithako zesibili eziqukethwe ziyahlukahluka ngemvelaphi ehlukene yedwala le-phosphate, ngokuvamile ziqukethe izingxenye zedwala i-Ca, i-Mg phosphate kanye ne-silicate. Ukukhishwa kwamanje kwe-phosphogypsum kwaminyaka yonke eShayina kungamathani ayizigidi ezingama-20, ukufuduka okuqongelelekayo cishe kwamathani ayizigidi eziyi-100, kuwukufuduka okukhulu kwemfucuza ye-gypsum, imfucuza ye-gypsum yayithathe inani elikhulu lenhlabathi futhi yakha intaba ye-slag yemfucuza, eyangcolisa kakhulu imvelo.
Ukusetshenziswa kwe-phosphogypsum
1. Isetshenziswa kabanzi emkhakheni wezinto zokwakha, inani elikhulu le-phosphogypsum elisetshenziswayo kanye nendlela yayo yokusetshenziswa kobuchwepheshe obuvuthiwe yenziwa ngomshini wokugaya. Impuphu ecolekile yeplasta ye-gypsum ingasetshenziswa njengezinto zokwakha ekukhiqizeni imikhiqizo emisha kufaka phakathi i-gypsum esikhundleni sokukhiqizwa kwe-gypsum cement retarder yemvelo, i-fine gypsum powder yokwakha, ukukhiqizwa kwebhodi leplasta, i-gypsum block nokunye okunjalo.
2. I-phosphogypsum enziwe yaba ne-acidic, icebile kakhulu nge-sulfur, i-calcium, i-magnesium nezinye izakhi zokulandelela, ngaphezu kwalokho esetshenziswa kabanzi ekwakheni, emigwaqweni nakwezinye izinjongo, kodwa futhi nasekuthuthukiseni i-saline-alkali conditioner soil, idlale indima ebalulekile ekunciphiseni ukuguguleka komhlabathi. Ngaphezu kwalokho, i-phosphogypsum ingalungiswa futhi njengomanyolo osebenza isikhathi eside kanye neminye imifino eluhlaza.
3. I-Phosphogypsum inendawo enkulu kakhulu yokuthuthukiswa. Emkhakheni wezimboni, i-phosphogypsum esetshenziswa ukukhiqiza i-sulfuric acid kanye ne-simende i-ammonium sulfate, i-potassium sulfate kanye neminye imikhiqizo ngezindlela ezahlukene zokucubungula, inikeza ukusebenza okugcwele enanini layo elikhethekile.
Ukugeleza kwenqubo yokuchithwa kwe-phosphogypsum
Uhlelo lokukhetha imodeli yomshini wokwenza impuphu ye-Phosphogypsum
I-HLM okwamanje isetshenziswa kabanzi emakethe njengokukhetha kokuqala komshini wokugaya oqondile wokugaya i-phosphogypsum, ngenxa yokusebenzisa kwayo amandla aphansi, usayizi wokuphakelayo, kulula ukulungisa ubuncane bomkhiqizo; inqubo ilula futhi kunezinye izinzuzo zokusebenzisa amaminerali angewona awensimbi kufaka phakathi imakethe ye-gypsum.
Ukuhlaziywa kwamamodeli okugaya
I-Hong Cheng vertical grinding mill -- i-HLM roller vertical milling ihlanganisa kusukela ekomiseni, ekugayeni, ekuhlukaniseni, ekuthuthweni iyonke, esetshenziswa kakhulu ekugayeni nasekucubunguleni usimende, i-clinker, i-desulfurization yesitshalo samandla nge-lime powder, i-slag powder, i-manganese ore, i-gypsum, amalahle, i-barite, i-calcite nezinye izinto. I-mill ikakhulukazi yakhiwe ngohlaka oluyinhloko, i-feeder, i-classifier, i-blower, izinto zokufaka amapayipi, i-hopper, izinhlelo zokulawula ze-elekthronikhi, izinhlelo zokuqoqa, njll., iyimishini yokugaya ethuthukisiwe kakhulu, ephumelelayo, neyonga amandla.
Isigaba I: Ukuchotshozwa kwezinto zokusetshenziswa
Izinto ezinkulu ze-phosphogypsum zichotshozwa yi-crusher kuze kube yilapho ukuphakelwa kuncane khona (15mm-50mm) okungangena emshinini wokugaya.
Isigaba II: Ukugaya
Izinto ezincane ze-phosphogypsum ezichotshoziwe zithunyelwa endaweni yokugcina izinto nge-elevator, bese zithunyelwa ekamelweni lokugaya lesitsha ngokulinganayo nangobuningi yi-feeder ukuze zigaywe.
Isigaba III: Ukuhlukaniswa
Izinto ezigayiwe zilinganiswa ngohlelo lokulinganisa, kanti impuphu engafaneleki ilinganiswa ngohlelo lokuhlukanisa bese ibuyiselwa emshinini oyinhloko ukuze igaywe kabusha.
Isigaba V: Ukuqoqwa kwemikhiqizo eqediwe
Impuphu evumelana nobuncane igeleza ngepayipi kanye negesi bese ingena eqoqweni lokuqoqa uthuli ukuze ihlukaniswe futhi iqoqwe. Impuphu eqoqwe ithunyelwa esigungwini somkhiqizo oqediwe ngedivayisi yokudlulisa ngembobo yokukhipha, bese ipakishwa yithangi lempuphu noma i-automatic packer.

Umshini wokugaya we-phosphogypsum waseGuilin Hongcheng usebenza kahle futhi usezingeni eliphezulu. Awuxazululi nje kuphela inkinga yokwelashwa kwe-phosphogypsum ngempumelelo, kodwa futhi nempuphu ye-gypsum ecutshunguliwe izoletha izinzuzo ezinkulu kwezomnotho. Ukunqunywa nokuqaliswa kwale phrojekthi ye-phosphogypsum kungavula ngempumelelo izintambo eziphezulu, eziphakathi nezingezansi zemboni yamakhemikhali ye-phosphogypsum, kuqaphele ibhalansi ephumelelayo phakathi kokuthuthukiswa kwemboni yamakhemikhali ye-phosphogypsum kanye nemvelo yemvelo, futhi kukhuthaze intuthuko esheshayo yemboni yokusetshenziswa kwemithombo ye-phosphogypsum. Ukugaya kuyisigaba esibalulekile ekucutshungulweni kwe-phosphogypsum. Umshini wokugaya we-gypsum okhethekile waseGuilin Hongcheng ungafinyelela ukuchotshozwa okusebenzayo nokuzinzile kwe-phosphogypsum, okuyindlela efanelekile yokukhetha imishini yokugaya.
