1.1 Isishwankathelo seplanti yokulungisa amalahle
I-Longquan Coal Preparation Plant yeNkampani ye-Taiyuan Coal Gasification yinkqubo enkulu ye-double-system ene-design capacity ye-5.00Mt / a evelisa kakhulu amalahle e-coking kwaye ithathela ingqalelo ukuveliswa kwamalahle ashushu.Inkqubo ye-slime erhabaxa yeplanti yokulungisa amalahle yenza i-5% yezinga lokuvelisa amalahle akrwada kwaye inomthamo wokusetyenzwa kweyure oyi-56.82t/h.
1.2 Inkqubo yokuhlela
Inkqubo yokulungisa amalahle kuyilo lweplanti yokulungisa amalahle imi ngolu hlobo lulandelayo: Emva kokuba amalahle esuliwe kwaye ahluzwa (isikrini se-desliming yi-1mm), i-50～1mm yahlulwe sisitshingitshane esinemveliso ezintathu esineziphene ezinobunzima obuphakathi. , 1～0.25mm I-slime yamalahle erhabaxa yahlulwe yi-TBS, kunye ne-0.25mm ye-slime ecolekileyo yamalahle ifunyanwa ngokujiya kunye nokucoca njengemveliso yamalahle ephakathi.
2.1 Ukwahlula kunye nenkqubo yokubuyisela i-slime erhabaxa phambi kwenguqu yobugcisa
Ukwahlula kunye nenkqubo yokubuyisela i-slime e-coarse phambi kokuguqulwa kobugcisa be-Longquan Coal Preparation Plant yile: i-cyclone concentration + ye-TBS ukwahlula + i-cyclone concentration + ye-arc sieve desliming kunye ne-dewatering + i-centrifuge dewatering.Inkqubo ethile iboniswe kuMfanekiso 1.
Umzobo 1 Itshati yokuqukuqela kwenkqubo yokwahlulwa kwe-slime erhabaxa phambi kwenguqu kubuchwepheshe
2.2 Kukho ingxaki
Itheyibhile ye-1 ibonisa idatha yovavanyo lwe-sieving yegalelo le-curved sieve kunye ne-over-the-screen xa i-sieve egobileyo yayisetyenziselwa ukusika kunye nokwahlula i-TBS yokugxilwa kokuphuphuma phambi kokuguqulwa kobugcisa.Ukususela ekuthelekisweni kwedatha yovavanyo lokuhlola, kunokubonwa ukuba umehluko phakathi komxholo womlotha wezinto ezingenayo kunye ne-sieve ingaphantsi kwe-5%, ebonisa ukuba ukusebenza kakuhle kokuhlolwa kwe-arc sieve kuphantsi kunye nomphumela wokunciphisa umlotha. uhlwempuzeke kakhulu.
Itheyibhile 1 Uvavanyo lokuhlola idatha ye-arc sieve ngaphambi kokuguqulwa kweteknoloji
I-Longquan Coal Preparation Plant inothuthu oluphezulu, i-ganggue sludge, uthuthu lwangaphakathi oluphezulu, isivuno esincinci, kunye nomxholo omkhulu wemveliso ephakathi.Ke ngoko, kwimveliso yokwenyani, uyilo lwantlandlolo lokwahlulwa kwe-slime erhabaxa kunye nenkqubo yokubuyisela ikakhulu inezi ngxaki zilandelayo:
Inkqubo yokuqala ithatha isikrini esimile njenge-arc esine-screening esezantsi esebenzayo ukusika i-coarse, i-sludge kunye nokukhupha amanzi okuphuphuma kwe-TBS.Ngenxa yodaka olukhulu lwenzeka yodaka kumalahle akrwada kunye nesiqulatho esiphakamileyo sodaka oluluthuthu oluluthuthu, ngokuqinisekileyo luya kubangela: isikrini esigobileyo siqulethe udaka oluninzi oluluthuthu olucolekileyo, olukhokelela kwisiqulatho sothuthu olurhabaxa. namalahle acocekileyo;Isikrini esigobileyo sisebenzisa intsimbi engatyiwayo Isikrini esisityiweyo sinesithuba esikhulu sesikrini kwaye kulula ukusinxiba, nto leyo eya kubangela ukuba isixa esikhulu sothuthu olurhabaxa oluphantsi lulahlekane kwaye luphulukane namalahle acocekileyo acocekileyo.Ngexesha elifanayo, isikrini kufuneka sitshintshwe rhoqo.
3.1 Isicwangciso senguqu kubuchwepheshe
Ukuze kuphuculwe izinga lokubuyisela amalahle acocekileyo kunye neenzuzo zezoqoqosho, i-Longquan Coal Preparation Plant idibene ne-Anhui Fangyuan Plastic Co., Ltd.Emva komboniso, yamkela ngokuthe ngqo i-Anhui Fangyuan Plastic Co., Ltd. ukuvelisa ukusebenza kakuhle kovavanyo, I-FY-HVS-1500 elaminated high-frequency screen kunye nesiphumo esihle se-deilting ithatha indawo yesikrini esigobileyo ngokufanelekileyo nangempumelelo ukusika imveliso ye-TBS ephuphumayo kunye nesikrini. yona.
3.2 Ulwakhiwo kunye nomgaqo-nkqubo wokusebenza we-FY-HVS-1500 elaminethiweyo isikrini sefrikhwensi ephezulu.
I-Fangyuan FY-HVS-1500 isikrini esiphezulu esipakishweyo luhlobo lwezixhobo zoomatshini ezisebenzisa i-vibration ephezulu-frequency ye-screen surface kunye nobunzima bezinto eziphathekayo ukufezekisa ukuhlelwa ngokobukhulu bamasuntswana ezinto.Ulwakhiwo lwayo luqulunqwe ikakhulu ngumsasazi, i-feeder, kunye nezakhelo zesikrini eziphezulu nezisezantsi., Imotor ye-vibration ephezulu, i-hopper yokuqokelela imveliso kwisikrini, itanki yokuqokelela imveliso phantsi kwesikrini, isakhelo kunye neqonga lenkxaso.Umgaqo osebenzayo womatshini we-sieve uboniswe kuMfanekiso 2. Iimpawu zayo eziphambili kunye neenzuzo zilandelayo.
Umfanekiso wesi-3 Indawo yokuhlola amalahle apakishweyo
