1.1 Isishwankathelo sendawo yokulungisa amalahle
I-Longquan Coal Preparation Plant yeTaiyuan Coal Gasification Company yinkqubo enkulu enezixhobo ezimbini ezinomthamo woyilo we-5.00Mt/a evelisa ikakhulu amalahle okupheka kwaye ithathela ingqalelo ukuveliswa kwamalahle ashushu. Inkqubo yeslime erhabaxa yesityalo sokulungiselela amalahle ibandakanya i-5% yezinga lokuveliswa kwamalahle aluhlaza kwaye inomthamo wokucubungula ngeyure we-56.82t/h.
1.2 Inkqubo yokuhlela
Inkqubo yokulungiselela amalahle kuyilo lwesityalo sokulungiselela amalahle yile ilandelayo: Emva kokuba amalahle aluhlaza esusiwe kwaye evalwe (isikrini sokususa amalahle yi-1mm), i-50 ～1mm yahlulwe yinkanyamba ekhupha amalahle kunye nengenaxinzelelo enemveliso ezintathu, i-1 ～0.25mm I-coarse coal slime yahlulwe yi-TBS, kwaye i--0.25mm fine coal slime ifunyanwa ngokutyeba kunye nokucinezela isihluzi njengemveliso yamalahle ephakathi.
2.1 Inkqubo yokwahlula nokubuyisela uthuli olurhabaxa ngaphambi kotshintsho lobugcisa
Inkqubo yokwahlula nokubuyisela ulwelo olurhabaxa ngaphambi kotshintsho lobuchwephesha lweLongquan Coal Preparation Plant yile: uxinaniso lwenkanyamba + ukwahlukana kweTBS + uxinaniso lwenkanyamba + ukuhluzwa kwe-arc sieve desliming kunye nokukhupha amanzi + ukuhluzwa kwe-centrifuge. Inkqubo ethile iboniswe kuMfanekiso 1.
Umfanekiso 1 Itshathi yokuhamba kwenkqubo yokwahlulwa kweslime embi ngaphambi kotshintsho lwetekhnoloji
2.2 Kukho ingxaki
Itheyibhile 1 ibonisa idatha yovavanyo lokusila yento efakwe kwisihluzo esigobileyo kunye nezinto eziphezu kwesikrini xa isihluzo esigobileyo sasisetyenziselwa ukusika nokwahlulahlula i-TBS concentrate explosion ngaphambi kotshintsho lobugcisa. Ukusuka kuthelekiso lwedatha yovavanyo lokusila, kunokubonwa ukuba umahluko phakathi komxholo wothuthu lwezinto ezingenayo kunye nesihluzo ungaphantsi kwe-5%, nto leyo ebonisa ukuba ukusebenza kakuhle kwesihluzo se-arc kuphantsi kwaye isiphumo sokunciphisa uthuthu sibi kakhulu.
Itheyibhile 1 Idatha yovavanyo lokuhlola isihluzo se-arc ngaphambi kotshintsho lobuchwepheshe
Isityalo sokulungiselela amalahle saseLongquan sinomthamo ophezulu wothuthu, udaka olukhulu lwe-gangue, uthuthu lwangaphakathi oluphezulu, isivuno esiphantsi soxinzelelo, kunye nomxholo omkhulu wemveliso ephakathi. Ke ngoko, kwimveliso yokwenyani, uyilo lokuqala lwenkqubo yokwahlulahlula i-slime kunye nokubuyisela imeko luneengxaki ezilandelayo:
Inkqubo yokuqala isebenzisa isikrini esimile okwe-arc esinokusebenza okuphantsi kokucoca ukuze kunqunyulwe i-grey, i-sludge kunye ne-dehydrate ukugcwala kwe-TBS concentrate. Ngenxa yento enodaka enkulu ye-gangue kumalahle aluhlaza kunye nomxholo ophezulu wodaka oluthambileyo olunomlotha ophezulu, ngokuqinisekileyo iya kubangela: isikrini esigobileyo sinodaka oluninzi oluthambileyo olunomlotha ophezulu, okubangela umxholo ophezulu womlotha wamalahle aqinileyo nacocekileyo; isikrini esigobileyo sisebenzisa intsimbi engagqwaliyo. Isikrini esine-slots sinomsantsa omkhulu wesikrini kwaye kulula ukusinxiba, nto leyo eya kubangela ukuba i-low-ash coarse slime ilahleke kwaye ilahlekelwe yi-grey coal. Kwangaxeshanye, isikrini kufuneka sitshintshwe rhoqo.
