Ngo-2015, umsunguli uCui Weihua wembula ilungelo lobunikazi: indlela yokulungisa i-calcium carbonate ekhanyayo ehlanzekile kakhulu kusuka ku-slag yensimbi. Ingabe kungenzeka ukwenza i-calcium carbonate ehlanzekile kakhulu kusuka ku-slag yensimbi usebenzisa i-slag yensimbi umshini wokugaya oqondile?

Ngokusho kwe-China Powder Technology Network, muva nje, "umugqa wokubonisa ukusetshenziswa kwezimboni we-carbonization method iron and steel slag comprehensive industrialization", iphrojekthi yenkontileka "yokuvuselela iMongolia ngesayensi nobuchwepheshe", yethulwe eBaotou. Lo msebenzi wakhiwa ngokubambisana yiBaotou Steel Group kanye neYukuang Environmental Protection Technology (Shanghai) Co., Ltd. Kubikwa ukuthi lo msebenzi usekelwe emiphumeleni "yomugqa wokukhiqiza wokuqinisekisa amatani ayi-10,000 wokusetshenziswa okuphelele kwe-steel slag ngendlela ye-carbonization". I-steel slag yenziwe nge-carbon ngokuphelele, futhi ekugcineni ikhiqiza imikhiqizo yezimboni efana nezinto eziqukethe i-calcium carbonate ehlanzekile kakhulu kanye nensimbi, ukuze kusetshenziswe kabusha izinsiza ze-steel slag. Uma kuqhathaniswa nobuchwepheshe bendabuko, ubuchwepheshe bokwelapha i-carbonization iron and steel slag bungathatha i-carbon dioxide ngqo njengezinto zokusetshenziswa ukuze zihlanganyele ekusabeleni ngenkathi kunciphisa ukukhishwa kwe-carbon dioxide, okunomphumela wokunciphisa i-carbon kabili, kufezwe umgomo wokunciphisa ukukhishwa kwegesi ebamba ukushisa kanye nokukhuthaza ukuthuthukiswa kwe-carbon low-carbon eyindilinga. Ngemva kokuphothulwa kwephrojekthi, amathani angu-424000 e-slag yensimbi angalungiswa minyaka yonke, kuyilapho amathani angaba ngu-100000 e-carbon dioxide angafakwa i-carbon (avalwe), kanye nomthamo wokukhiqiza wamathani angu-200000 e-calcium carbonate ehlanzekile kakhulu kanye namathani angu-310000 ezinto zensimbi ungafinyelelwa. Lo msebenzi uwukuhlola okwengeziwe kwezimboni, okungakhuthazwa kabanzi emabhizinisini afanayo. Ngenkathi kuhlangatshezwana nesidingo sokusetshenziswa okuphelele kwemfucuza eqinile, kuyasiza ekufezeni umgomo we-carbon peak kanye ne-carbon neutralization. Lokhu kusho ukuthi kungenzeka ukuthi iphrojekthi yokukhiqiza i-calcium carbonate ehlanzekile kakhulu isuka ku-slag yensimbi iyasebenza. Iphinde inikeze indlela entsha yokusetshenziswa okuphelele kwemfucuza eqinile ye-slag yensimbi.

Izici zobuchwepheshe eziyinhloko zokukhiqiza i-calcium carbonate emsulwa kakhulu kusuka ku-slag yensimbi yilezi ezilandelayo: okokuqala, gaya i-slag yensimbi ibe yimpuphu, veza i-calcium oxide yamahhala ku-slag yensimbi ebusweni be-slag yensimbi, khipha i-calcium oxide ku-slag yensimbi ngendlela emanzi nge-acetic acid engu-0.5%, uyihlunge bese uyicacisa, bese uyi-carbon dioxide ngegesi, bese uyikhipha amanzi emzimbeni, uyigeze, uyomise, uyipholise, uyishaye bese uyivala ukuze ukhiqize i-calcium carbonate ekhanyayo emsulwa kakhulu. I-calcium carbonate ekhanyayo emsulwa kakhulu isetshenziswa kabanzi njengokugcwalisa amathayili okwenziwa phansi, irabha, amapulasitiki, ukwenza amaphepha, izembozo, upende, uyinki, izintambo, izinto zokwakha, ukudla, imithi, izindwangu, ukudla, amazinyo okugcoba kanye neminye imikhiqizo. Kule nqubo, ubuncane bokugaya be-slag yensimbi kudinga ukufinyelela kuma-meshes angaphezu kuka-400. Hlobo luni lwemishini olungasetshenziswa ukufeza ukukhiqizwa okukhulu kwe-powder encane ye-slag yensimbi? Njengomkhiqizi ochwepheshe weinsimbiumshini wokugaya i-slag, I-HCMilling (Guilin Hongcheng) incoma ukuthi ukhetheI-HLM steel slagumshini wokugaya oqondile ukukhiqizwa kwempuphu ye-slag yensimbi. Njengamanje, inqubo yokwelapha impuphu ye-slag yensimbi emakethe ngokuyinhloko ingaphambi kokugaya + ukugaya kahle. I-slag yensimbi ingagaywa ibe ngaphezu kwama-micron angu-420 ngemva kokugaya ngezigaba ezimbili. Intengo yemishini, indawo yephansi kanye nokusetshenziswa kwamandla okumaphakathi konke kuyizimali ezinkulu.

Ithimba le-R&D le-HCMilling (Guilin Hongcheng) kanye nochwepheshe bemboni, ngokubambisana okujulile kanye nokuhlolwa, baqalise i-I-slag yensimbi yochungechunge lwe-HLMumshini wokugaya oqondile, engagaya i-powder ye-slag yensimbi ibe yisimo ngesikhathi esisodwa, ithuthukisa kakhulu inani lokusetshenziswa kwe-powder ye-slag yensimbi, futhi ivule imakethe yesicelo esingezansi. Kuyimishini ye-powder ye-slag micro yensimbi efanelekile yokonga izindleko, ukusetshenziswa kwamandla, indawo yaphansi, isivuno kanye nenani elengeziwe lemikhiqizo eqediwe.

Uma unesidingo sokukhiqizwa kanye nokucutshungulwa kwempuphu ye-slag yensimbi, sicela usithinte ukuze uthole imininingwane futhi usinikeze ulwazi olulandelayo:
