1.1 Ukubuka konke kwesitshalo sokulungiselela amalahle
I-Longquan Coal Preparation Plant ye-Taiyuan Coal Gasification Company iyisistimu enkulu enezinhlobo ezimbili enomthamo wokuklama ongu-5.00Mt/a ekhiqiza kakhulu amalahle okupheka futhi icabangele ukukhiqizwa kwamalahle ashisayo. Uhlelo lwe-slime oluqinile lwesitshalo sokulungiselela amalahle lubalelwa ku-5% wesilinganiso sokukhiqizwa kwamalahle aluhlaza futhi lunamandla okucubungula ngehora angu-56.82t/h.
1.2 Inqubo yokuhlunga
Inqubo yokulungiselela amalahle ekwakhiweni kwesitshalo sokulungiselela amalahle imi kanje: Ngemva kokuba amalahle aluhlaza esesusiwe futhi ahlolwe (isikrini sokususa amalahle siyi-1mm), ama-50 ～1mm ahlukaniswa yisiphepho esinzima esiphakathi nesinemikhiqizo emithathu esisusa amalahle nesingenangcindezi, i-1 ～0.25mm I-coarse coal slime ihlukaniswa yi-TBS, kanti i--0.25mm fine coal slime ibuyiswa ngokujiya bese ihlunga njengomkhiqizo wamalahle ophakathi.
2.1 Inqubo yokuhlukanisa nokubuyisela i-slime embi ngaphambi kokuguqulwa kobuchwepheshe
Inqubo yokuhlukanisa nokubuyisela i-slime ecolekile ngaphambi kokuguqulwa kobuchwepheshe be-Longquan Coal Preparation Plant yile: ukuhlushwa kwesiphepho + ukuhlukaniswa kwe-TBS + ukuhlushwa kwesiphepho + ukuhlushwa kwesihlupho se-arc ukusula nokususa amanzi + ukusula amanzi nge-centrifuge. Inqubo ethile iboniswe kuMfanekiso 1.
Isithombe 1 Ishadi lokugeleza kwenqubo yokuhlukaniswa kweslime esiqinile ngaphambi kokuguqulwa kobuchwepheshe
2.2 Kunenkinga
Ithebula 1 libonisa idatha yokuhlolwa kokuvinjelwa kokufakwa kwesihlungo esigobile kanye nezinto eziphezu kwesikrini lapho isihlungo esigobile sisetshenziswa ukusika nokuhlukanisa ukugcwala kwe-TBS concentrate ngaphambi kokuguqulwa kobuchwepheshe. Kusukela ekuqhathanisweni kwedatha yokuhlolwa kokuvinjelwa, kungabonakala ukuthi umehluko phakathi kokuqukethwe komlotha wezinto ezingenayo kanye nesihlungo ungaphansi kuka-5%, okubonisa ukuthi ukusebenza kahle kokuvinjelwa kwesihlungo se-arc kuphansi futhi umphumela wokunciphisa umlotha mubi kakhulu.
Ithebula 1 Idatha yokuhlola yokuhlola yesihlungi se-arc ngaphambi kokuguqulwa kobuchwepheshe
I-Longquan Coal Preparation Plant inomlotha omningi, udaka olukhulu lwe-gangue, umlotha omningi wangaphakathi, isivuno esincane sokugxila, kanye nokuqukethwe okukhulu komkhiqizo ophakathi. Ngakho-ke, ekusebenzeni kwangempela kokukhiqiza, ukwakheka kokuqala kwenqubo yokuhlukanisa i-slime kanye nokubuyisa ama-coarse slime ikakhulukazi kunezinkinga ezilandelayo:
Inqubo yokuqala isebenzisa isikrini esimise okwe-arc esinokusebenza okuphansi kokuhlola ukuze kunqunywe ukugcwala okuqinile, okungcolile kanye nokusula amanzi okuchichima kwe-TBS concentrate. Ngenxa yesimo esinzima sodaka se-gangue kumalahle angavuthiwe kanye nokuqukethwe okuphezulu kodaka oluqinile olunomlotha ophezulu, kuzobangela ngokungenakugwenywa: isikrini esigobile siqukethe inani elikhulu lodaka oluqinile olunomlotha ophezulu, okuholela ekuquketheni okuphezulu komlotha wamalahle aqinile futhi ahlanzekile; isikrini esigobile sisebenzisa insimbi engagqwali Isikrini esinezikhala sinesikhala esikhulu sesikrini futhi kulula ukusigqoka, okuzobangela ukuthi inani elikhulu lodaka oluqinile olunomlotha ophansi lulahleke futhi lulahlekelwe amalahle aqinile ahlanzekile. Ngesikhathi esifanayo, isikrini sidinga ukushintshwa njalo.
3.1 Uhlelo lokuguqula ubuchwepheshe
Ukuze kuthuthukiswe izinga lokubuyiselwa kwezinzuzo zamalahle ahlanzekile kanye nezomnotho, iLongquan Coal Preparation Plant ihlangene ne-Anhui Fangyuan Plastic Co., Ltd. ukuguqula uhlelo lokuhlukanisa i-slime oluqinile. Ngemva kokuboniswa, yamukela ngqo i-Anhui Fangyuan Plastic Co., Ltd. ukuze ikhiqize ukusebenza kahle kokuhlola okuphezulu, isikrini se-FY-HVS-1500 esine-laminated high-frequency esinomphumela omuhle wokususa i-silting sithatha indawo yesikrini esigobile ukuze sisike umkhiqizo we-TBS ogcwele kahle futhi siwuhlole ngempumelelo.
3.2 Isakhiwo kanye nesimiso sokusebenza sesikrini se-FY-HVS-1500 esine-laminated high frequency.
Isikrini esihlanganisiwe se-Fangyuan FY-HVS-1500 high-frequency stacked uhlobo lwemishini yemishini esebenzisa ukudlidliza okuphindaphindekayo kobuso besikrini kanye namandla adonsela phansi kwezinto ukuze kufezwe ukuhlukaniswa ngokwesayizi wezinhlayiya zezinto. Isakhiwo sayo sakhiwe kakhulu ngumsabalalisi, i-feeder, kanye nozimele besikrini abaphezulu nangaphansi. , Imoto yokudlidliza ephindaphindekayo, i-hopper yokuqoqa umkhiqizo esikrinini, ithangi lokuqoqa umkhiqizo ngaphansi kwesikrini, uhlaka kanye nepulatifomu yokusekela. Isimiso sokusebenza somshini wokuhluza siboniswe kuMfanekiso 2. Izici nezinzuzo zayo eziyinhloko yilezi ezilandelayo.
Umfanekiso 3 Indawo yokuhlolwa kwamalahle ahlanganisiwe
I-Longquan Coal Preparation Plant inomlotha omningi, udaka olukhulu lwe-gangue, umlotha omningi wangaphakathi, isivuno esincane sokugxila, kanye nokuqukethwe okukhulu komkhiqizo ophakathi.
