Iyini i-Silo Ye-Powder Yamakhemikhali?
Isiloli samakhemikhali okuyimpuphu siyisitsha esinzima, esimise okomgodi, esakhelwe ngokukhethekile ukugcina izinto eziningi, ukuvikela, nokukhipha ngokulawuleka izimpuphu zamakhemikhali ezomile, izinhlayiya, namaminerali—njenge-soda ash, i-titanium dioxide, izisekelo zokuhlanza, i-carbon black, izithasiselo zepulasitiki, nosawoti wezimboni ezahlukene.
Ezindaweni zanamuhla zokucubungula amakhemikhali, izikhungo zokukhiqiza, kanye nezikhungo zokusabalalisa izimboni, izinqolobane zamakhemikhali eziyimpuphu zisebenza njengezinqolobane ezibalulekile zempahla phakathi kwezinto zokusebenza eziluhlaza ezinkulu (njengamaloli amathangi nezimoto zikaloliwe) kanye nemigqa yokukhiqiza ezenzakalelayo eqhubekayo. Ngenxa yokuthi izimpuphu eziningi zamakhemikhali ziyagqoloja, zimunca umswakama, ziyasebenza ngamandla, noma zingaqhuma kalula, izinqolobane zamakhemikhali zidinga ubunjiniyela obukhethekile bezinsimbi, ukuvalwa okungangeni moya, kanye nezinhlelo eziqinile zokuphepha ukuze kuvinjwe ukungcola, ukugqwala kwesakhiwo, kanye nezingozi zemvelo.
Izici Eziyinhloko Zobunjiniyela Nokuphepha
Ukugcina izimpuphu zamakhemikhali zezimboni kuveza izinselele eziyinkimbinkimbi zamakhemikhali nezomshini ezingenakubhekwa iziloli ezijwayelekile zezolimo noma zamatshe. Iziloli zamakhemikhali zihlanganisa izingxenye ezibalulekile zobunjiniyela:
·
Ubunjiniyela Obukhethekile Bokumelana Nokugqwala: Ngokuya ngezakhiwo zamakhemikhali zomkhiqizo ogciniwe, iziloli zenziwa ngensimbi engagqwali esezingeni eliphezulu (njenge-304 noma i-316L), insimbi ecwebezelisiwe ekhethekile, noma insimbi yekhabhoni evikelwe ngamafutha e-epoxy amelana namakhemikhali noma i-fluoropolymer.
·
·
Ukuvimbela Ukuqhuma nokukhipha Umoya (Ukuthobela i-ATEX/NFPA): Izimpushana eziningi ezinhle zezinto eziphilayo nezingaphili zakha amafu othuli oluvuthayo lapho zintanta emoyeni. Amasilo afakwe amaphaneli okukhulula ukuqhuma, ama-rupture disc, nezinhlelo zokugxumeka phansi ezingenayo i-antistatic ukuze kukhishwe ngokuphepha amandla okuqhuma.
·
·
Ukuvala Okungangeni Moya Nokubuyisela Umhwamuko: Ukuze kuvinjelwe ukuthi umusi onobuthi ungaphumi noma umswakamo ovela emoyeni wonakalise amakhemikhali azwela umswakamo, amasilo avalwa ngokuphelele futhi ahlanganiswe nezinhlelo zokulinganisa umhwamuko ezivaliwe noma zokukhipha umoya.
·
·
Ukulayisha Okuthuthukile Kwe-Pneumatic Nokuhlunga: Kuhlome ngezintambo zokugcwalisa ezinomfutho ophezulu kanye nezihlungi zothuli ezinama-pulse-jet ezifakwe phezulu ezinemidiya yokuhlunga ekhethekile emelana namakhemikhali ukuze kuthathwe izinhlayiya ezincane ngesikhathi kuthululwa amaloli amathangi.

I-Matrix Yokuqhathanisa: Izinto Zesilo Se-Powder Yamakhemikhali
Into Yesilo / Ukufakwa Ngaphakathi | Ukumelana Namakhemikhali Nokugqwala | Ukumelana Nokuguguleka | Amandla Esakhiwo Nempilo Yokusebenza | Ukusetshenziswa Okufanele Kwamakhemikhali |
Insimbi Engagqwali (316L / 304) | Evelele (Ayisebenzi kumachiza amaningi, usawoti, nezincibilikisi) | Phezulu | Ehle Kakhulu (Impilo yokusebenza ende, ayikhiphi ubumba) | Amakhemikhali ahlanzekile kakhulu, imithi, nezimpushana eziyizinto ezisebenzayo |
Insimbi Yekhabhoni Efakwe i-Epoxy | Phakathi nendawo kuya Phezulu (Kuncike ekuhambisaneni kwamakhemikhali okumbozayo) | Phakathi nendawo | Phezulu (Kudinga ukuhlolwa nokumbozwa kabusha kwe-coating ngezikhathi ezithile) | Amakhemikhali ajwayelekile ezimbonini, izimpushana ezinama-alkali athambile |
Ingilazi Ehlanganiswe Nensimbi (GFS) | Ephakeme (Ingilazi engasebenzi imelana nezinga le-pH elinamandla) | Okuphawulekayo (Ubunzima be-Mohs obungu-6.0) | Okuhle kakhulu (Akudingi ukulungiswa, impilo engaphezu kweminyaka engu-30) | Amaminerali abolayo, izimpushana zokuhlanza, nosawoti wezimboni |
Izicelo Ezibalulekile Zezimboni
1.
Ukuhlanganiswa Kwamakhemikhali Nokukhiqiza: Ukugcina izinto ezingavuthiwe zamakhemikhali (njenge-soda ash, i-sodium sulfate, nezinto ezixubile zamakhemikhali) ngaphambi kokuxuba.
2.
3.
Ukukhiqiza Izinto Zokuhlanza Nensipho: Ukugcina izinto ezinkulu zokwakha, ama-surfactant, nezimpushana eziqeda umbala ezindaweni ezinomswakama olawulwayo.
4.
5.
Ukuhlanza Amanzi Namanzi Angcolile: Ukugcina izinto zokwelapha ezomile ezinjenge-activated carbon, i-lime, nama-coagulant powders ngaphambi kokufakwa okulawulwayo emanzini.
6.
7.
Ukuhlanganiswa Kwepulasitiki Ne-Polymer: Ukuqukatha izinto ezigcwele zamaminerali, imibala, nama-flame retardant powders.

Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Kungani izilinda zempushana zamakhemikhali zidinga izinto zangaphakathi ezikhethekile noma izinsimbi ezikhethekile?
Impendulo: Izimpushana eziningi zamakhemikhali ziyagqwala, zine-asidi, noma zine-alkali. Ukuzigcina ensimbi evamile kubangela ukugqwala okusheshayo, ukugqwala okunjengemigodi, nokwehla kwesakhiwo, kuyilapho kungcolisa umkhiqizo wamakhemikhali ngezicucu zomhlwa. Izinto ezingagqwali njenge-stainless steel noma i-glass-fused-to-steel zivikela ukuhlaselwa kwamakhemikhali.
Umbuzo: Izimpushana zamakhemikhali ezingavutha ziphathwa kanjani ngokuphepha esilindeni?
A: Izinhlayiya ezicolekile zamakhemikhali ezintantayo emoyeni zingakha izingxube eziqhumayo. Amasilo amakhemikhali afaka amaphaneli okukhulula ukuqhuma ahambisana ne-ATEX/NFPA, amasistimu okuphahla aqhubekayo ukuze kuqedwe ugesi omile, nezinzwa zokuthola izinhlansi ukuze kuvinjelwe izehlakalo zokuqhuma okungazelelwe.
Q: Kuvinjelwa kanjani ukuthi umswakamo wonakalise izinhlayiya zamakhemikhali ezimunca umswakamo?
A: Amasilo avalwa ngokuphelele ukuze angangeni imvula nomswakamo womoya. Izinhlelo eziningi zamakhemikhali ezizwelayo zisebenzisa futhi ukufakwa kwe-nitrogen noma izinhlelo zokungenisa umoya owomisiwe ukuze kugcinwe umoya owomile ngaphakathi, kuvinjelwe ukubumba nokuhlangana.
Q: Izinhlayiya zamakhemikhali zilayishwa futhi zikhishwe kanjani esilweni?
A: Izimpushana zidluliselwa esilweni ngokusebenzisa izinhlelo zokuthutha eziphefumulayo ezivela emalolini amakhulu ethangi noma ezitimeleni zikaloliwe kusetshenziswa umoya ohlungiwe noma i-nitrogen. Ukukhishwa kwenzeka ngomthelela womhlaba nge-hopper cone engezansi, kulawulwa ama-rotary airlock noma ama-screw conveyor anikezela izikali zezitshalo ezizenzakalelayo.
