1.1 Uhlolojikelele lwemboni yokulungisa amalahle
I-Longquan Coal Preparation Plant ye-Taiyuan Coal Gasification Company iwuhlelo olukhulu olukabili olunamandla okuklama angu-5.00Mt/a olukhiqiza ikakhulukazi amalahle okuphekela futhi lucabangela ukukhiqizwa kwamalahle ashisayo.Isistimu ye-slime eqinile yesikhungo sokulungiselela amalahle yenza u-5% wezinga lokukhiqiza amalahle aluhlaza futhi inamandla okucubungula ngehora angu-56.82t/h.
1.2 Inqubo yokuhlunga
Inqubo yokulungisa amalahle ekwakhiweni kwemboni yokulungisa amalahle imi kanje: Ngemva kokuba amalahle aluhlaza esuliwe futhi ahlolwa (isikrini se-desliming singu-1mm), i-50～1mm ihlukaniswa yisiphepho esinamandla esinemikhiqizo emithathu esinesisindo esiphakathi. , 1～0.25mm I-slime yamalahle eqinile ihlukaniswa yi-TBS, kanye ne--0.25mm coal slime itholwa ngokujiya nangokuhlunga njengomkhiqizo wamalahle omaphakathi.
2.1 Inqubo yokuhlukanisa kanye nokuthola kabusha i-slime eqinile ngaphambi koshintsho lobuchwepheshe
Inqubo yokuhlukanisa nokubuyisela i-slime eqinile ngaphambi kokuguqulwa kobuchwepheshe be-Longquan Coal Preparation Plant ithi: i-cyclone concentration + TBS separation + cyclone concentration + arc sieve desliming and dewatering + centrifuge dewatering.Inqubo ethile iboniswa kuMfanekiso 1.
Umdwebo 1 Ishadi lokugeleza kwenqubo lokuhlukaniswa kwe-slime emaholoholo ngaphambi kokuguqulwa kwezobuchwepheshe
2.2 Kunenkinga
Ithebula 1 libonisa idatha yokuhlola yokusefa yokokufaka kwesisefo esigobile kanye nokokusebenza kwesikrini lapho isisefo esigobile sisetshenziselwa ukusika nokuhlukanisa ukuchichima kokugxilisa ingqondo kwe-TBS ngezigaba ngaphambi kokuguqulwa kobuchwepheshe.Kusukela ekuqhathanisweni kwedatha yokuhlolwa kokuhlolwa, kungabonakala ukuthi umehluko phakathi kokuqukethwe komlotha wezinto ezingenayo kanye nesisefo ungaphansi kuka-5%, okubonisa ukuthi ukusebenza kahle kokuhlolwa kwesisefo se-arc kuphansi kanye nomphumela wokunciphisa umlotha. impofu kakhulu.
Ithebula 1 Idatha yokuhlola yokuhlola yesisefo se-arc ngaphambi kwenguquko yezobuchwepheshe
I-Longquan Coal Preparation Plant inomlotha omningi, i-ganggue sludge, umlotha wangaphakathi ophezulu, isivuno esiphansi, kanye nokuqukethwe komkhiqizo omkhulu omaphakathi.Ngakho-ke, ekusebenzeni kwangempela kokukhiqiza, idizayini yokuqala yokuhlukaniswa kwe-slime eqinile kanye nenqubo yokubuyisela inezinkinga ezilandelayo:
Inqubo yokuqala yamukela isikrini esimise okwe-arc esinekhono lokuhlola eliphansi ukusika amaholo, udaka kanye nokukhipha amanzi ukuchichima kokugxilisa ingqondo kwe-TBS.Ngenxa yodaka olubucayi lwe-ganggue emalahleni aluhlaza kanye nokuqukethwe okuphezulu kodaka olucolekile olunomlotha omningi, izobangela nakanjani: isikrini esigobile siqukethe inani elikhulu lodaka olucolekile olunomlotha omningi, okuholela ekubeni nomlotha omningi womlotha. namalahle ahlanzekile;isikrini esigobile sisebenzisa insimbi engagqwali Isikrini esigobile sinegebe lesikrini esikhulu futhi kulula ukusigqoka, okuzobangela inani elikhulu le-slime elimahhadla elinomlotha omncane ukuthi liduke futhi lilahlekelwe amalahle ahlanzekile.Ngesikhathi esifanayo, isikrini sidinga ukushintshwa njalo.
3.1 Uhlelo lwezinguquko kwezobuchwepheshe
Ukuze kuthuthukiswe izinga lokutholwa kwezinzuzo zamalahle ahlanzekile nezomnotho, I-Longquan Coal Preparation Plant ehlanganiswe ne-Anhui Fangyuan Plastic Co., Ltd. ukuguqula uhlelo lokuhlukanisa i-slime emaholoNgemuva kokuboniswa, yamukela ngokuqondile i-Anhui Fangyuan Plastic Co., Ltd. ukuze ikhiqize ukusebenza kahle kokuhlola, Isikrini se-FY-HVS-1500 esakhiwe ngefrikhwensi esinomphumela omuhle we-deilting sithatha indawo yesikrini esigobile ukuze sisike ngempumelelo nangempumelelo umkhiqizo nesikrini esichichimayo se-TBS. yona.
3.2 Isakhiwo kanye nesimiso sokusebenza se-FY-HVS-1500 elaminethiwe isikrini sefrikhwensi ephezulu.
Isikrini esistakiwe se-Fangyuan FY-HVS-1500 high-frequency stack iwuhlobo lwezisetshenziswa eziwumshini ezisebenzisa ukudlidliza kwe-high-frequency ye-screen surface kanye namandla adonsela phansi okokusebenza ukuze kufinyelelwe kusigaba ngokuya ngosayizi wezinhlayiyana zezinto.Isakhiwo sayo sakhiwe kakhulu ngumsabalalisi, isiphakeli, namafreyimu esikrini angaphezulu naphansi., Injini yokudlidliza enemvamisa ephezulu, i-hopper yokuqoqwa komkhiqizo esikrinini, ithangi lokuqoqa umkhiqizo ngaphansi kwesikrini, uhlaka kanye nenkundla yosekelo.Isimiso sokusebenza somshini we-sieve siboniswa ku-Figure 2. Izici zayo eziyinhloko kanye nezinzuzo zimi kanje.
Umfanekiso 3 Indawo yokuhlolwa kwamalahle estakiwe
