Ukuqonda Amalahle Okuphekela: Umhlahlandlela Ophelele

Lo mhlahlandlela unikeza umbono ophelele we ukupheka amalahle, ihlola izakhiwo zayo, ukusetshenziswa kwayo, ukuguquguquka kwezimakethe, nomthelela kwezemvelo. Sihlola izinhlobo ezahlukene ukupheka amalahle, inqubo yayo yokukhiqiza, kanye nendima yayo ebalulekile ezimbonini ezihlukahlukene. Funda mayelana nembulunga yonke ukupheka amalahle imakethe, okuhlanganisa abadlali ababalulekile kanye nezitayela zesikhathi esizayo. Lolu lwazi lubalulekile kunoma ubani obambe iqhaza embonini yensimbi noma onentshisekelo yokuqonda lesi sisetshenziswa esibalulekile.

Ukupheka amalahle, owaziwa nangokuthi amalahle e-metallurgical, wuhlobo oluthile lwamalahle anento encane eguquguqukayo kanye nokuqukethwe kwekhabhoni ephezulu. Ngokungafani nezinye izinhlobo zamalahle asetshenziselwa ukukhiqiza ugesi, ukupheka amalahleIzakhiwo ezihlukile ziyenza ifaneleke ukusetshenziswa ezithandweni eziqhumayo ukukhiqiza insimbi nensimbi. Ikhono layo lokukwazi ukumelana namazinga okushisa aphakeme ngaphandle kokuwohloka libalulekile enqubweni yokupheka, okuhlanganisa ukushisisa amalahle ukuze kuxoshwe izingxenye eziguquguqukayo futhi kwakhiwe i-coke eqinile, enezimbotshana.

Izinhlobo zamalahle okuphekela

Ukupheka amalahle ihlukaniswa ngokusekelwe ezicini ezimbalwa, okuhlanganisa izinga layo (izinga le-metamorphism), okuqukethwe kwento eguquguqukayo, kanye nezakhiwo zokupheka. Ngokuvamile, i-high-volative ukupheka amalahle, ukuguquguquka okuphakathi ukupheka amalahle, futhi iyaguquguquka ephansi ukupheka amalahle zihlukene, ngayinye inezici zayo ezihlukile kanye nezindlela ezisetshenziswa ngayo ekwenzeni insimbi. Inhlanganisela yezinhlobo ezahlukene ze ukupheka amalahle ivame ukuthuthukiswa ukuze kuzuzwe ikhwalithi ye-coke oyifunayo yezinqubo ezithile zokukhiqiza insimbi.

Inqubo Yokupheka

Inqubo yokupheka iyisinyathelo esibalulekile ekukhiqizeni insimbi. Kubandakanya ukushisa ukupheka amalahle ngokungabikho komoya (i-pyrolysis) kuhhavini we-coke emazingeni okushisa aphezulu (cishe 900-1000 ° C) amahora amaningana. Le nqubo iguqula amalahle abe yi-coke, i-porous carbon material enamandla amakhulu kanye nokusebenza kabusha, okubalulekile ekunciphiseni insimbi yensimbi esithandweni somlilo. Imikhiqizo yenqubo yokupheka, njengegesi ye-coke oven ne-coal tar, nazo ziyizinsiza ezibalulekile ezinezinhlelo zokusebenza ezihlukahlukene zezimboni.

Umhlaba jikelele ukupheka amalahle imakethe ithonywa kakhulu yizici ezifana namazinga okukhiqiza insimbi, ukukhula komnotho womhlaba, kanye nemithethonqubo yezemvelo. Abakhiqizi abakhulu nabathengi be ukupheka amalahle agxile ngokwendawo, okuholela ekuguquguqukeni kochungechunge lokuhlinzeka. Intengo ye ukupheka amalahle iyaguquguquka futhi imvamisa ikhombisa ibhalansi phakathi kokuhlinzekwa kanye nesidingo emakethe yomhlaba. Ukuqonda lezi zinguquko zemakethe kubalulekile kumabhizinisi abandakanyekayo ku ukupheka amalahle imboni.

Ukucatshangelwa Kwemvelo

Ukukhishwa kanye nokusetshenziswa kwe ukupheka amalahle zibe nemiphumela ebalulekile kwezemvelo. Imisebenzi yezimayini ingaholela ekucekeleni phansi komhlaba, ukungcoliswa kwamanzi, kanye nokukhishwa kwesisi esibamba ukushisa. Inqubo yokupheka ngokwayo iphinde ikhiqize ukukhishwa, okuhlanganisa ukungcola okufana ne-sulfur oxides ne-particle matter. Imboni yensimbi igxile kakhulu ekunciphiseni umthelela wemvelo we ukupheka amalahle ukusetshenziswa ngokusungula izinto ezintsha zobuchwepheshe kanye nezinqubo ezizinzile.

Amathrendi Azayo Embonini Yamalahle Yokupheka

Ikusasa le ukupheka amalahle imboni yakhelwa yizici eziningana, okuhlanganisa intuthuko yezobuchwepheshe, imithethonqubo yezemvelo, kanye nesidingo esikhulayo sensimbi. Ucwaningo lusaqhubeka lokuthuthukisa izindlela ezihlanzekile nezisebenza ngempumelelo ukupheka amalahle ukukhiqiza kanye nokusetshenziswa. Ukwamukelwa kobunye ubuchwepheshe, obufana nokusetshenziswa kwe-biomass noma izinto ezigaywe kabusha ekwenzeni insimbi, nakho kungaba nomthelela omkhulu esidingweni sesikhathi esizayo ukupheka amalahle.

Abadlali Ababalulekile Embonini Yamalahle Yokupheka

Izinkampani eziningi ezinkulu zamazwe ngamazwe zidlala indima ebalulekile emhlabeni jikelele ukupheka amalahle imakethe. Lezi zinkampani zibambe iqhaza emikhakheni eyahlukene yemboni, kusukela kwezezimayini nokucubungula kuya ekuhwebeni nasekusabalaliseni. Ukuqonda abadlali ababalulekile namasu abo ezimakethe kunikeza imininingwane mayelana nokuguquguquka kwemboni kanye nokuthambekela kwekusasa. Isibonelo, i-Inner Mongolia Xinxin Silicon Industry Co.,Ltd (https://www.xinxinsilicon.com/) ungumdlali obalulekile embonini ye-silicon, egqamisa ukuxhumana kwezinto ezihlukahlukene ngaphakathi kwendawo yezimboni ebanzi.
