Izindlela Eziphumelelayo Zokukhiqiza I-Sodium Hydrosulfide kanye Nokugeleza Kwenqubo

I-Sodium hydrosulfide (NaHS) iyikhemikhali ebalulekile engakhiqizi izinto eziphilayo esetshenziswa kabanzi emikhakheni eyahlukene efana nemboni yamakhemikhali, i-metallurgy, imithi, izibulala-zinambuzane, i-organosilicon, ukwelashwa kwamanzi amdaka, kanye nokucutshungulwa kwamaminerali. Lesi sihloko sizonikeza isingeniso esifushane ngezindlela zokukhiqiza ze- Sodium hydrosulfide , okuhlanganisa izinto zokusetshenziswa, ukugeleza kwenqubo, izinyathelo zokusebenza, imishini, ukulawulwa kwekhwalithi, kanye nezinyathelo zokuphepha.

Ama-Raw material

Izinto zokusetshenziswa eziyinhloko zokukhiqizwa kwe-sodium hydrosulfide (NaHS) yi-sodium hydroxide ne-hydrogen sulfide. I-sodium hydroxide kufanele ibe yezinga lezimboni ngobumsulwa obungekho ngaphansi kwama-96%, futhi igesi ye-hydrogen sulfide kufanele ihambisane nezindinganiso zikazwelonke ezifanele.

Ukugeleza kwenqubo

1. Ukulungiswa kweSodium Hydroxide Solution : I-sodium hydroxide eqinile ifakwa emanzini afanele bese ivuselelwa ukuze incibilike, kwakhiwe isixazululo se-sodium hydroxide.

2. Ukwethulwa kwe-Hydrogen Sulfide : Igesi ye-hydrogen sulfide ifakwa esixazululweni se-sodium hydroxide ukuze isabele futhi ikhiqize i-sodium hydrosulfide.

3. Ukuhlukaniswa Kwe-Centrifugal : Izinto ezicwebezelisiwe zifakwa ekuhlukanisweni kwe-centrifugal ukuze kutholakale umkhiqizo oqediwe we-sodium hydrosulfide.

4. Ukomisa : Umkhiqizo we-sodium hydrosulfide otholakala ekuhlukanisweni kwe-centrifugal uyomiswa.

Izinyathelo Zokusebenza

1. Ngokwesilinganiso esibaluliwe, engeza i-sodium hydroxide eqinile ethangini lokuhlakazeka, bese wengeza inani elifanele lamanzi bese ugoqa ukuze ancibilike, wakhe isixazululo se-sodium hydroxide.

2. Vula i-hydrogen sulfide gas valve bese wethula igesi ye-hydrogen sulfide kusisombululo se-sodium hydroxide, ulawule izinga lokugeleza kwegesi kanye nezinga lokushisa lokusabela ukuze kube lula ukusabela okukhiqiza i-sodium hydrosulfide.

3. Lapho i-pH yenhlanganisela yokusabela ifinyelela inani elithile, misa ukugeleza kwegesi, pholisa ingxube yokusabela ezingeni lokushisa elithile, futhi uvumele i-sodium hydrosulfide ukuba ikhanye ngaphandle.

4. Beka i-crystallized material ku-centrifuge yokuhlukaniswa kwe-centrifugal ukuze uthole umkhiqizo oqediwe we-sodium hydrosulfide.

5. Dlulisa umkhiqizo we-sodium hydrosulfide otholwe ekuhlukaniseni i-centrifugal uwuyise emshinini wokomisa wokwelapha ukuze uthole umkhiqizo wokugcina we-sodium hydrosulfide.

Isisetshenziswa

Izinto ezidingekayo ukuze kukhiqizwe i-sodium hydrosulfide zihlanganisa ithangi lokuhlakaza, igedlela lokusabela, ithangi le-crystallization, i-centrifuge, nemishini yokomisa. Lawa madivaysi kufanele ahambisane namazinga afanele okukhiqiza kanye nezidingo zokuphepha, futhi adinga ukunakekelwa njalo nokuhlolwa ukuze kuqinisekiswe ukusebenza okuvamile nokusetshenziswa okuphephile.

Ikhwalithi yokulawula

1. Igesi ye-Hydrogen sulfide inobuthi futhi iyingozi, ngakho-ke kubalulekile ukulawula ngokuqinile izinga lokugeleza kwegesi kanye nezinga lokushisa lokusabela ukuze kuvinjelwe ukuvuza kwegesi kanye nezigameko zobuthi bezisebenzi.

2. Indawo yokukhiqiza kufanele ifakwe izimpawu eziyisixwayiso zokuphepha kanye nezindawo zokucisha umlilo ukuze kuqinisekiswe ukuphepha kwabasebenzi kanye nokuthuthukisa amakhono okubhekana nezimo eziphuthumayo.

3. Abasebenzisi kufanele bathole ukuqeqeshwa kochwepheshe ukuze baqonde izici zomkhiqizo nezinqubo zokusebenza, baqinisekise ukuphepha nokuzinza kwenqubo yokusebenza.

Njengento ebalulekile yamakhemikhali eluhlaza, i-sodium hydrosulfide idinga ukulawula okuqinile phezu kwezici ezifana nekhwalithi yempahla eluhlaza, izimo zokusabela, kanye nekhwalithi yomkhiqizo phakathi nenqubo yokukhiqiza ukuze kuqinisekiswe ikhwalithi kanye nesivuno somkhiqizo. Ukwengeza, kubalulekile ukuqinisa ukuqaliswa nokuphathwa kwezinyathelo zokuphepha ukuze kuqinisekiswe ukuphepha nokuzinza kwenqubo yokukhiqiza.
