Nzira yekugadzira uye nzira yekuyerera kwe sodium hydrosulfide

Ini. IniNnhanganyaya

Sodium hydrosulfide ( NaHS ) ikemikari inokosha muOrganic inoshandiswa zvakanyanya muminda yakasiyana-siyana yakadai se chemical engineering, metallurgy , pharmaceuticals , pesticides , uye textile . Chinyorwa chino chichatsanangura nzira dzekugadzira Sodium hydrosulfide , kusanganisira zvinhu zvakabikwa , process flow , processing steps, midziyo, Quality Control , uye Safety Measures.

II. Mbichi zvinhu

MA muzvinhu zvakagadzirwa pakugadzira Sodium hydrosulfide iSodium hydroxide neHydrogen sulfide . Sodium Hydroxide inofanira kunge iri yemhando yeindasitiri ine kuchena kweinenge 96 % , uye Hydrogen Sulfide Gas inofanira kutevedzera mitemo yenyika.

III. Process Flow

Maitiro ekugadzira Sodium Hydrosulfide ndeaya anotevera:

1. Kugadzirira Sodium hydroxide : Wedzera Sodium hydroxide yakasimba mumvura yakakodzera , kurunga kuti inyungudike, wobva wagadzira sodium hydroxide solution.

2. Kuiswa kweHydrogen Sulfide: Isa hydrogen sulfide gasi mumushonga we sodium hydroxide kuti iite chimwe chinhu uye igadzire sodium hydrosulfide.

3. Kugadzira kristalo: Kutonhodza mhinduro yereaction kuti igadzire crystallize uye kuwana makristaro eSodium hydrosulfide.

4. Kupatsanura kwepakati : Ita kupatsanura kwepakati pechinhu chakagadzirwa kuti uwane chigadzirwa chakagadzirwa nesodium hydrosulfide.

5. Kuomesa: Omesa chigadzirwa che sodium hydrosulfide chapedzwa chakawanikwa kubva mukupatsanurwa kwe centrifugal.

IV. Matanho Okushanda

1. Zvinoenderana nechiyero chakatarwa, wedzera yakasimba sodium hydroxide kune tangi yekunyungudutsa, wedzera huwandu hwakakodzera hwemvura, uye kurunga kunyungudika, uchigadzira sodium hydroxide solution.

2. Vhura iyo hydrogen sulfide gasi vharafu uye unza hydrogen sulfide gasi musodium hydroxide solution, uchidzora gasi kuyerera uye kuita tembiricha kugadzira sodium hydrosulfide.

3. Kana pH yemhinduro yemhinduro yasvika paACH ine kukosha kwakati, misa kuyerera kwegasi, tonhodza mhinduro yemhinduro kusvika patembiricha yakatarwa, uye bvumira sodium hydrosulfide kuti iite crystallize.

4. Isa iyo crystallized zvinhu mu centrifuge yekuparadzanisa centrifugal kuti uwane iyo sodium hydrosulfide chigadzirwa.

5. Isa iyo sodium hydrosulfide chigadzirwa chakawanikwa kubva ku centrifugal kupatsanurwa muchina chekuomesa chekuomesa kurapwa kuti uwane yekupedzisira sodium hydrosulfide chigadzirwa.

V. Equipment

Midziyo inodiwa pakugadzira sodium hydrosulfide inosanganisira tangi rekunyungudutsa, kettle yereaction, tangi recrystallization, centrifuge, uye michina yekuomesa. Midziyo iyi inofanirwa kutevedzera mitemo yekugadzira yakakodzera uye Zvinodiwa zvekuchengetedza , uye inofanirwa kugara ichichengetwa uye ichiongororwa kuti ive nechokwadi chekuti inoshanda zvakachengeteka uye zvakajairika.

VI. Kutungamirirwa kwehutano

Kuti zvive nechokwadi chekuti zvigadzirwa zve sodium hydrosulfide zvakanaka , matanho akasimba ekudzora mhando anofanira kuitwa. Izvi zvinosanganisira zvinotevera:

1. Raw Material Kudzora: Ita shuwa kuti mhando yesodium hydroxide uye hydrogen sulfide gasi inosangana nezvinodiwa.

2. Kudzora Kudzora: Dzora kuyerera kwegasi, kuita tembiricha, uye nguva yekuve nechokwadi chemhando uye goho reiyo sodium hydrosulfide inogadzirwa.

3. Kuongororwa Kwechigadzirwa : Ita bvunzo dzemhando yepamusoro pa sodium hydrosulfide inogadzirwa, kusanganisira kuchena, hunyoro, pH kukosha , nezvimwe zviratidzo, kuti uve nechokwadi chekuti mhando yechigadzirwa inosangana nezvinodiwa.

VII. Matanho ekuchengetedza

Maitiro ekugadzira sodium hydrosulfide ane njodzi dzekuchengetedza , saka matanho ekuchengetedza anoenderana nawo anofanira kutorwa:

1. Gasi rehydrogen sulfide rine chepfu uye rinokuvadza; saka, zvakakosha kudzora zvakanyanya kuyerera kwegasi uye tembiricha yekuita kuti gasi ribude uye zviitiko zve chepfu yevashandi zvisaitike.

2. Zviratidzo zvekunyevera nezvekuchengetedza uye nzvimbo dzinodzivirira moto dzinofanira kuiswa panzvimbo yekugadzira kuitira kuti vashandi vagare vakachengeteka uye kuvandudza kugona kwevanoda rubatsiro panguva yenjodzi.

3. Vashandi vanofanirwa kudzidziswa zvehunyanzvi kuti vanzwisise hunhu hwechigadzirwa uye maitiro ekushanda , vachiona kuchengetedzeka uye kugadzikana kwemaitiro ekushanda.

VIII. Mhedziso

Sechinhu chakakosha chemakemikari , kugadzirwa kwe sodium hydrosulfide kunoda kudzora zvakanyanya kunaka kwezvinhu zvakagadziriswa, mamiriro ekuita, uye mhando yechigadzirwa kuti ive nechokwadi chemhando uye goho rechigadzirwa. Pamusoro pezvo, zvakakosha kusimbisa kuiswa nekutarisira matanho ekuchengetedza kuti ive nechokwadi chekuchengetedzeka uye kugadzikana kweMaitiro Ekugadzira.
