Mekhoa e Metle ea ho Hloekisa Sodium Hydrosulfide Hantle

Background

Indastering ea petrochemical, libaka tsa ho hloekisa hangata li hlahisa likhase tse nang le asiti nakong ea ts'ebetso ea ts'ebetso joalo ka ho qhala ha vacuum le ho petsoha ha catalytic. Likhase tsena tse nang le asiti hangata li na le 85%-95% ea hydrogen sulfide, 3%-10%. k'habone dioxide, 2%-5% ea likhase tsa tlhaho, le likarolo tse ling tse 0.5%-3%. Liindasteri tse nyane le tse mahareng hangata li sebelisa tharollo ea soda e bakang ho bola ea 30% ho monya likhase tse nang le asiti tse hlahisoang nakong ea ho hloekisa. Soda e bakang ho bola e arabela le hydrogen sulfide ho theha. Sodium Hydrosulfide. Ha motsoako oa sodium hydrosulfide ka tharollo o fihla ho 30%, tharollo e ntse e tsepamisitsoe haholoanyane. Ka mor'a ho felloa ke metsi le ho tsepamisa mohopolo, sodium hydrosulfide content ka tharollo e ka fihla ho 70%, 'me sodium hydrosulfide e ntan'o sebetsoa ka lilae.

Leha ho le joalo, boteng ba carbon dioxide ka likhase tse acidic bo hlahisa litšila tsa sodium carbonate nakong ea phekolo, e amang bohloeki ba sehlahisoa sa sodium hydrosulfide. Ho feta moo, ho sebelisa sekhechana se bulehileng ho arola sodium hydrosulfide e qhibilihisitsoeng ho ka lebisa ho ts'ebetso ea oksijene moeeng, ho hlahisa thiosulfate, e atisang ho senyeha le ho thata ho e boloka. Ho khaola ho bulehileng ho boetse ho atisa ho lokolla likhase tse halefisang, tse silafatsang tikoloho ea tlhahiso.

Mokhoa oa ho sebetsa

1. Centrifugal Separation:

Fetisetsa motsoako oa sodium hydrosulfide concentrated ho tloha tanka ea mahloriso ho ea ho screw centrifuge e otlolohileng bakeng sa karohano, ho fumana letsoai le kristale le ho qhibiliha monohydrate sodium hydrosulfide.

2. Vacuum Insulation le Cooling:

Romela monohydrate sodium hydrosulfide e qhibilihisitsoeng, ka mor'a karohano ea letsoai e khanyang, ho tanka ea vacuum insulation bakeng sa ho futhumatsa. Ebe u e pompa ka har'a vacuum paddle cooler bakeng sa ho pholile le ho tiisa maqephe a tšesaane.

3. Automatic Bagging:

Maqephe a sodium hydrosulfide a ntšoa ka valve ea linaleli ka har'a mochini oa mekotla oa othomathike bakeng sa ho paka.

Ho feta moo, mokhoa oa ho hloekisa sodium hydrosulfide o kenyelletsa mehato e latelang:

1. Fetisetsa sodium hydrosulfide concentrated solution ho tloha tanka ea mahloriso ho ea ho screw centrifuge e otlolohileng bakeng sa karohano, ho fumana letsoai le kristale le ho qhibiliha monohydrate sodium hydrosulfide.

2. Romela letsoai le entsoeng ka kristale le fumanoang ho tloha centrifugation ho ea ho se omisang, moo le qalang ho felloa ke metsi 'meleng karolong e futhumatsang ea lera le ka holimo la se omisitsoeng, ebe le kena karolong e pholileng ea lera le ka tlaase bakeng sa ho pholisa pele le bokelloa e le moemeli oa phekolo ea metsi bakeng sa tšebeliso ea morao-rao.

3. The molten monohydrate sodium hydrosulfide, ka mor'a hore letsoai le arohane ka kristale, le romelloa ka tanka ea ho kenya vacuum bakeng sa ho futhumatsa. E ntan'o pompeloa ka har'a vacuum paddle cooler bakeng sa ho pholile le ho tiisa maqephe a masesaane.

4. Lipampiri tsa sodium hydrosulfide li ntšoa ka valve ea linaleli ka har'a mochine oa mekotla o ikemetseng bakeng sa ho paka.

5. Mokhahlelo oa khase o ntšitsoeng ka tanka ea ho kenya vacuum le pholileng ea vacuum paddle e phekoloa ka mokhoa oa ho hloekisa khase ea litšila.

fihlela qeto e

Mokhoa ona o qala ka ho arola matsoai a kristale a tsoakiloeng, joalo ka sodium carbonate, ho tsoa ho sodium hydrosulfide concentrated solution. Ka mor'a moo, monohydrate sodium hydrosulfide e qhibilihisitsoeng e tiisoa ka ho toba ho ba maqephe a tšesaane ho sebelisa vacuum paddle cooler. Qetellong, sehlahisoa se phuthetsoe ho sebelisoa mochine oa mekotla o itekanetseng. Motsoako oa litšila tsa sodium carbonate sehlahisoa o fokotsehile ho tloha ho 2.4% ho ea ho 0.3%. Ts'ebetso ea ho pholisa e etsoa tikolohong ea khatello e mpe, e fokotsang monyetla oa hore sodium hydrosulfide e kopane le moea le ho kenella ka oxidation, e thibelang hantle ho senyeha ha sehlahisoa. Tšebeliso ea tsamaiso e koetsoeng ka ho feletseng bakeng sa tlhoekiso ea sodium hydrosulfide e tiisa hore ha ho na likhase tse halefisang tse lokolloang nakong ea ts'ebetso, ho qoba tšilafalo ea bobeli ho tikoloho. Lipampiri tsa sodium hydrosulfide li kentsoe ka ho toba, li thibela tšilafalo nakong ea polokelo. Ho phaella moo, moqapi ona o na le mokhoa o bonolo, o hlokang lisebelisoa tse fokolang, 'me o na le litšenyehelo tse tlaase.
