Ọna iṣelọpọ ati ṣiṣan ilana ti iṣuu soda hydrosulfide

I. Ifihan

Sodium hydrosulfide (NaHS) jẹ kemikali eleto ti o ṣe pataki ti a lo ni ọpọlọpọ awọn aaye bii imọ-ẹrọ kemikali, irin, awọn oogun, awọn ipakokoropaeku, Ati hihun. Nkan yii yoo ṣafihan awọn ọna iṣelọpọ ti Iṣuu soda hydrosulfide, pẹlu awọn ohun elo aise, ṣiṣan ilana, awọn igbesẹ iṣiṣẹ, ohun elo, iṣakoso didara, ati awọn igbese ailewu.

II. Awọn ohun elo aise

Awọn ohun elo aise akọkọ fun iṣelọpọ iṣuu soda hydrosulfide jẹ iṣuu soda hydroxide ati hydrogen sulfide. Sodium hydroxide yẹ ki o jẹ ti ipele ile-iṣẹ pẹlu mimọ ti ko din ju 96%, ati pe gaasi hydrogen sulfide yẹ ki o ni ibamu pẹlu awọn iṣedede orilẹ-ede.

III. Sisan ilana

Sisan ilana iṣelọpọ fun iṣuu soda hydrosulfide jẹ bi atẹle:

1. Igbaradi Sodium Hydroxide: Ṣafikun iṣuu soda hydroxide to lagbara si iye omi ti o yẹ, ru lati tu, ki o mura ojutu soda hydroxide kan.

2. Ifihan ti Hydrogen Sulfide: Ṣe afihan gaasi hydrogen sulfide sinu ojutu iṣuu soda hydroxide lati fesi ati gbejade iṣuu soda hydrosulfide.

3. Crystallization: Tutu ojutu idahun si crystallize ati gba awọn kirisita sodium hydrosulfide.

4. Iyapa Centrifugal: Ṣe ipinya centrifugal lori ohun elo crystallized lati gba ọja iṣuu soda hydrosulfide ti pari.

5. Gbigbe: Gbẹ ọja iṣuu soda hydrosulfide ti o ti pari ti a gba lati iyapa centrifugal.

IV. Awọn Igbesẹ Iṣẹ

1. Ni ibamu si ipin pàtó kan, ṣafikun iṣuu soda hydroxide to lagbara si ojò itusilẹ, ṣafikun iye omi ti o yẹ, ki o ru lati tu, ngbaradi ojutu iṣuu soda hydroxide.

2. Ṣii àtọwọdá gaasi sulfide hydrogen ki o ṣafihan gaasi hydrogen sulfide sinu ojutu iṣuu soda hydroxide, ṣiṣakoso iwọn sisan gaasi ati iwọn otutu ifa lati ṣe agbejade iṣuu soda hydrosulfide.

3. Nigbati pH ti ojutu ifaseyin ba de iye kan, da ṣiṣan gaasi duro, jẹ ki ojutu ifasẹyin si iwọn otutu kan pato, ati gba iṣuu soda hydrosulfide laaye lati di crystallize.

4. Gbe ohun elo crystallized sinu centrifuge fun iyapa centrifugal lati gba ọja iṣuu soda hydrosulfide.

5. Gbe ọja iṣuu soda hydrosulfide ti o gba lati ipinya centrifugal sinu ẹrọ gbigbe kan fun itọju gbigbe lati gba ọja iṣuu soda hydrosulfide ikẹhin.

V. Ohun elo

Ohun elo ti o nilo fun iṣelọpọ iṣuu soda hydrosulfide pẹlu ojò itusilẹ, kettle ifaseyin, ojò crystallization, centrifuge, ati ohun elo gbigbe. Awọn ẹrọ wọnyi yẹ ki o ni ibamu pẹlu awọn iṣedede iṣelọpọ ti o yẹ ati awọn ibeere ailewu, ati pe wọn nilo lati ṣetọju nigbagbogbo ati ṣayẹwo lati rii daju ailewu ati iṣẹ ṣiṣe deede.

VI. Iṣakoso didara

Lati rii daju didara awọn ọja iṣuu soda hydrosulfide, awọn igbese iṣakoso didara ti o muna gbọdọ wa ni imuse. Eyi pẹlu awọn abala wọnyi:

1. Iṣakoso Ohun elo Raw: Rii daju pe didara iṣuu soda hydroxide ati gaasi hydrogen sulfide ni ibamu pẹlu awọn iṣedede ti o yẹ.

2. Iṣakoso ifaseyin: Ṣakoso iwọn sisan gaasi, iwọn otutu ifaseyin, ati akoko lati rii daju didara ati ikore ti iṣuu soda hydrosulfide ti a ṣe.

3. Idanwo Ọja: Ṣe idanwo didara lori iṣuu soda hydrosulfide ti a ṣejade, pẹlu mimọ, akoonu ọrinrin, iye pH, ati awọn itọkasi miiran, lati rii daju pe didara ọja ba awọn iṣedede ibamu.

VII. Awọn Igbesẹ Aabo

Ilana iṣelọpọ ti iṣuu soda hydrosulfide ṣafihan awọn eewu ailewu kan, nitorinaa awọn igbese ailewu ti o baamu nilo lati mu:

1. Hydrogen sulfide gaasi jẹ majele ati ipalara; nitorina, o jẹ awọn ibaraẹnisọrọ to muna šakoso awọn gaasi sisan oṣuwọn ati lenu otutu lati se gaasi jo ati eniyan ti oloro awọn iṣẹlẹ.

2. Awọn ami ikilọ aabo ati awọn ohun elo ija ina yẹ ki o ṣeto ni aaye iṣelọpọ lati rii daju aabo eniyan ati mu awọn agbara idahun pajawiri pọ si.

3. Awọn oniṣẹ gbọdọ gba ikẹkọ alamọdaju lati loye awọn ohun-ini ti ọja ati awọn ilana ṣiṣe, ni idaniloju aabo ati iduroṣinṣin ti ilana iṣiṣẹ.

VIII. Ipari

Gẹgẹbi ohun elo aise kemikali pataki, iṣelọpọ ti iṣuu soda hydrosulfide nilo iṣakoso to muna lori didara ohun elo aise, awọn ipo ifaseyin, ati didara ọja lati rii daju didara ati ikore ọja naa. Ni afikun, o ṣe pataki lati teramo imuse ati iṣakoso ti awọn igbese ailewu lati rii daju aabo ati iduroṣinṣin ti ilana iṣelọpọ.
