Mafi kyawun Hanyoyi don Tsarkake Sodium Hydrosulfide Da Kyau

Tarihi

A masana'antar man fetur, matatun mai yawanci suna samar da iskar gas mai guba yayin ayyukan sarrafawa kamar narkar da iskar gas da fashewar catalytic. Waɗannan iskar gas mai guba gabaɗaya sun ƙunshi kashi 85%-95% na hydrogen sulfide, kashi 3%-10% na Carbon dioxide, kashi 2%-5% na iskar gas mai guba, da sauran abubuwan da ke cikin 0.5%-3%. Ƙananan matatun mai da matsakaitan girma galibi suna amfani da maganin soda mai guba kashi 30% don shanye iskar gas mai guba da ake samarwa yayin tacewa. Caustic soda yana amsawa da hydrogen sulfide don samar da Sodium Hydrosulfide . Lokacin da yawan sodium hydrosulfide a cikin maganin ya kai kashi 30%, maganin yana ƙara tarawa. Bayan bushewa da yawan amfani, sinadarin sodium hydrosulfide a cikin maganin zai iya kaiwa kashi 70%, sannan ana sarrafa sodium hydrosulfide zuwa yanka.

Duk da haka, kasancewar carbon dioxide a cikin iskar acidic yana haifar da datti na sodium carbonate yayin aikin jiyya, wanda ke shafar tsabtar samfurin sodium hydrosulfide. Bugu da ƙari, yin amfani da slicer mai buɗewa don yanki narkakkar sodium hydrosulfide na iya haifar da halayen oxygenation tare da iskar oxygen a cikin iska, yana samar da thiosulfate, wanda ke da wuyar lalacewa kuma yana da wuyar adanawa. Yanke buɗaɗɗen kuma yana kula da sakin iskar gas mai ban haushi, yana gurɓata yanayin samarwa.

Hanyar sarrafawa

1. Rabuwar Tsakiya:

Canja wurin maganin maida hankali na sodium hydrosulfide daga tankin maida hankali zuwa madaidaicin dunƙule centrifuge don rabuwa, samun gishiri mai crystallized da narkakken monohydrate sodium hydrosulfide.

2. Bakin Insulation da sanyaya:

Aika narkakkar monohydrate sodium hydrosulfide, bayan rabuwar gishiri mai crystallized, zuwa tanki mai rufe fuska don dumama. Sa'an nan, zuba shi a cikin injin daskarewa don sanyaya da kuma ƙarfafa cikin zanen gado na bakin ciki.

3. Jaka ta atomatik:

Ana fitar da zanen gadon sodium hydrosulfide ta hanyar bawul ɗin tauraro a cikin injin jaka ta atomatik don marufi.

Bugu da ari, hanyar tsarkakewa don sodium hydrosulfide ta ƙunshi matakai masu zuwa:

1. Canja wurin sodium hydrosulfide mayar da hankali bayani daga maida hankali tank zuwa a kwance dunƙule centrifuge don rabuwa, samun crystallized gishiri da narkakkar monohydrate sodium hydrosulfide.

2. Aika gishiri mai crystallized da aka samo daga centrifugation zuwa na'urar bushewa, inda za a fara fara bushewa a cikin sashin dumama na saman Layer na na'urar, sa'an nan kuma shigar da sashin sanyaya na ƙananan Layer don sanyaya kafin a tattara shi a matsayin wakili na ruwa don amfani daga baya.

3. Narkakkar monohydrate sodium hydrosulfide, bayan rabuwar gishiri mai crystallized, ana aika shi zuwa tanki mai rufi don dumama. Daga nan sai a zuba shi a cikin na'ura mai sanyaya ruwa don sanyaya da kuma daskarewa cikin zanen gado na bakin ciki.

4. Ana fitar da zanen gadon sodium hydrosulfide ta hanyar bawul ɗin tauraro a cikin injin jaka ta atomatik don marufi.

5. Tsarin iskar gas ɗin da aka samo daga tanki mai rufewa da kuma na'urar sanyaya mai sanyaya ruwa ana kula da shi ta hanyar tsarin kula da iskar gas.

Kammalawa

Wannan hanya ta farko tana raba gaurayen gishirin crystallized, irin su sodium carbonate, daga maganin tattarawar sodium hydrosulfide. Sa'an nan, narkakkar monohydrate sodium hydrosulfide kai tsaye yana ƙarfafa shi cikin zanen gado na bakin ciki ta amfani da injin sanyaya. A ƙarshe, an haɗa samfurin ta amfani da injin jaka ta atomatik. Matsakaicin ƙarancin ƙarancin sodium carbonate a cikin samfurin ya ragu daga 2.4% zuwa 0.3%. Ana aiwatar da tsarin sanyaya a cikin yanayin matsa lamba mara kyau, wanda ke rage yuwuwar sodium hydrosulfide ya shiga cikin hulɗa da iska kuma yana jurewa iskar oxygen, yadda ya kamata ya hana lalacewar samfur. Yin amfani da cikakken tsarin rufewa don tsarkakewa na sodium hydrosulfide yana tabbatar da cewa ba a saki iskar gas mai ban haushi a lokacin tsari, guje wa gurɓataccen gurɓataccen yanayi na biyu. Jakunkuna na sodium hydrosulfide ana ɗaukar su kai tsaye, suna hana kamuwa da cuta yayin ajiya. Bugu da ƙari, wannan ƙirƙira tana da tsari mai sauƙi, yana buƙatar kayan aiki kaɗan, kuma yana da ƙarancin farashi.
