Yiziphi isitini esiyinjwayelo okulahlwa kuzo izishisi zikadoti?

Izinto zokushisela imfucuza zihlukaniswe zibe: indawo yokushisela imfucuza eqinile kamasipala, isishisi esiphakathi, isishisi sokushisela imfucumfucu, isishisi sokushisela imfucumfucu, isishisi sokushisela imfucumfucu, isishisi sokushisela imfucumfucu yemboni ye-rotary, isithando somlilo sohlobo lwe-grate.

Kuya

Ngenxa yokuthi kunezinhlobo eziningi zemfucumfucu ezingakwazi ukuhlukaniswa ngokuphelele, inani le-caloric likadoti nalo lihlukile. Ukuze kuqinisekiswe ukuthi i-incinerator kadoti igcina ukusebenza kahle ngaphansi kokushisa okuphezulu kwesikhathi eside, kuyadingeka ukucabangela ukukhethwa kwezinto eziphikisayo ezivela ezicini eziningi. Ikakhulukazi izitini ze-silicon carbide. Izinto ezifakwayo ikakhulukazi ezenziwe ngobumba, amapulasitiki ane-alumina ephezulu, asekelwe kubumba, kanye nezinsimbi ezisekelwe ku-silicon carbide. Ngenxa yokugqwala okuphezulu kwezinto zokushisela imfucuza, ukusetshenziswa kwezinto ezilahlayo kuhlala kuvela. Ukusetshenziswa kwe-silicon carbide castables kanye nama-phosphates kuhlanganiswe ne-high-alumina castables kukhula kancane kancane ngoba lezi zinsimbi ezimbili zinokumelana okuhle kokugqoka.

Isisekelo sokukhetha sezinto eziphikisayo: ama-incinerators ahlukene anezimo zokusebenza ezihlukene, futhi amazinga okushisa ahlukene okusetshenziswa kwangaphakathi adinga izakhiwo ezihlukene zezinto eziphikisayo. Ngakho-ke, izinto eziphikisayo ezinezakhiwo ezahlukene kufanele zikhethwe ngokuya ngendawo yazo yokusebenza futhi zisebenzise izinga lokushisa. Izinga lokushisa elisebenzayo le-incinerator kadoti liyi-1200 ℃-1400 ℃. Igesi igqwala kakhulu ezintweni eziphikisayo ngesikhathi sokushiswa, futhi phansi kwesithando somlilo, ophephela, nezindonga ezisemaceleni zigugile kakhulu futhi ziyathinteka. Ngakho-ke, ukukhetha kwe-lining yekhwalithi ephezulu nakho kuzoqhubeka nokubuyekezwa.

Khetha izinto eziphikisayo ngokuya ngendawo yokusebenza. Engxenyeni yokufaka ye-incinerator yemfucuza, njengoba okokufaka nokuwa kwemfucuza kufanele kuthintane nezinto ezibonakalayo, futhi izinga lokushisa le-port yokufaka livame ukushintsha, i-refractory iyadingeka ukuze ibe nokumelana okuhle kokugqoka kanye nokumelana nokushaqeka okushisayo. Ukuze uzinze, izitini zobumba zingasetshenziswa.

Ekamelweni lokumisa kanye negumbi elivuthayo le-incinerator yemfucuza, imfucuza kanye nendwangu yesithando somlilo kuthintana ngokuqondile emazingeni okushisa aphezulu. Ngakolunye uhlangothi, i-slag izonamathela emgqeni wesithando somlilo, futhi ngakolunye uhlangothi, ukungcola kuzohlasela uhlaka lwesithando somlilo. Ngesikhathi esifanayo, ukufakwa kwemfucuza kuzobangela izinguquko zokushisa nakanjani. Ngakho-ke, izinto eziphikisayo azidingeki nje kuphela ukuthi zingagugi, zikwazi ukumelana nokugqwala, futhi kube nzima ukunamathela, kodwa futhi zikwazi ukumelana ne-alkali kanye ne-oxidation. Ngokuvamile, izitini zobumba, izitini eziphezulu ze-alumina, izitini ze-SiC, ama-castable namapulasitiki asetshenziswa.

Khetha izinto eziphikisayo ngokuya ngezinga lokushisa elisetshenziswayo, izishisi zemfucumfucu ezihlukene, izingxenye ezihlukene zokusebenzisa, namazinga okushisa ahlukene okusetshenziswa: izinga lokushisa lokusetshenziswa kophahla, izindonga ezisemaceleni, nezibasi zegumbi elivuthayo yi-1000-1400, kanye ne-refractoriness ye-1750-1790. ingakhethwa. Izitini eziphezulu ze-alumina nezitini zobumba, amapulasitiki ane-refractoriness ye-1750-1790 nawo angasetshenziswa.

Izidingo zezinto eziphikisayo kufanele zibe namaphuzu alandelayo:

1. Sebenzisa imikhiqizo enamandla kakhulu futhi engagugi ukumelana nokuguga nokugeleza komoya okuqinile;

2. Kumele ibe nokungazweli kwe-asidi nokuzinza ukuze imelane nokugqwala kwe-asidi;

3. Ukushaqeka okushisayo nakho kuyisici esibalulekile esingenakunakwa;

Okwesine, kufanele ibe nokuguguleka kwe-CO ukuvimbela ulwelwesi ekuqhekekeni;

Okwesihlanu, ukukhethwa kwezinto zokufakelwa, ngokusho kwezimo ezihlukene, khetha izinto zokukhanyisa ukukhanya ezifanele ingxenye ngayinye.
