intshayelelo

Kwishishini le-electroplating , ii-cyanides zisetyenziswa kakhulu njengezongezo ezibalulekileyo ze-electroplating. Zinokuphucula kakhulu umgangatho kunye nokusebenza kakuhle kwee-layers ze-electroplating. Nangona kunjalo, ngexesha lenkqubo ye-electroplating, kuveliswa igesi yokukhupha i-cyanide , equlethe izinto ezinobuthi obukhulu njenge-hydrogen cyanide (HCN). Oku kusongela kakhulu okusingqongileyo nakwimpilo yabantu. Ke ngoko, unyango olusebenzayo lwegesi yokukhupha i-cyanide ye -electroplating lubaluleke kakhulu.

Imithombo ye-Electroplating Cyanide Exhaust Gas

1. IiTanki Zokugquma Nge-Electroplating : Ngexesha lokufakelwa nge-electroplating, ngenxa yokuguquguquka kwe-electrolyte kunye negesi eveliswa yi-electrolytic reaction, igesi yokukhupha ephumayo ene-cyanide iyakhutshwa. Umzekelo, kwi-cyanide electroplating yegolide nesilivere, ii-cyanide compounds kwisisombululo sokugquma ziya kuguquguquka phantsi kwesenzo sobushushu kunye nomsinga wombane.

2. Iinkqubo zokucoca : Emva kokusebenzisa i-electroplating, xa izinto zokusebenza zicocwa ngezisombululo zokucoca ezineCyanides , inani elincinci le-cyanides liya kuguquka. Nokuba ubuninzi be-cyanides kwisisombululo sokucoca buphantsi, ukuqokelelana kwexesha elide kunye nokuguquka kunokubangela iingxaki zongcoliseko.

3. Unyango lwamanzi amdaka : Ukuba unyango lwamanzi amdaka olusebenzisa i-electroplating alufanelekanga, igesi ye-cyanide inokuphuma. Ngexesha lokunyanga amanzi amdaka aqukethe i-cyanide, ukuba iimeko zokusabela azilawulwa kakuhle, ukubola kwe-cyanides kunokuvelisa igesi ye-HCN kwaye kungene emoyeni.

4. Izixhobo Ezincedisayo : Izixhobo ezifana neenkqubo zokungenisa umoya kunye nezixhobo zokufudumeza nazo zinokuvelisa ubuninzi begesi ephumayo ngexesha lokusebenza. Nangona ubungakanani buncinci, xa kujongwa ubuthi obuphezulu be-cyanides, abunakubethwa ngoyaba.

Iimpawu ze-Electroplating Cyanide Exhaust Gas

1. Ubuthi Obuphezulu : Iikhompawundi zeCyanide, ingakumbi iHCN, ziyingozi kakhulu. Nokuba ziphantsi kakhulu, zinokubangela umonakalo emzimbeni womntu. Ukuphefumla igesi yokukhupha umoya equlethe i-cyanide kunokubangela iimpawu ezifana nentloko ebuhlungu, isiyezi, ukuphefumla okufutshane, kwaye kwiimeko ezinzima, kunokuba yingozi ebomini.

2. Isiphumo Esiphantsi Sokuxinanisa Kodwa EsiQokelelweyo : Ngokubanzi, uxinzelelo lwegesi yokukhupha i-cyanide nge-electroplating luphantsi kakhulu, kodwa ngenxa yokuveliswa okuqhubekayo ngexesha lenkqubo yokufakelwa i-electroplating, ukuba ayinyangwa kakuhle, umphumo oqokelelweyo uya kubangela ungcoliseko lwexesha elide kwindalo esingqongileyo.

Inkqubo yoNyango lwe-Electroplating Cyanide Exhaust Gas

1. I-Exhaust Gas Collection

Ezi zixhobo zokuqokelela kufuneka zenziwe ngokuhambelana nenkqubo ethile yokuvelisa kunye noyilo ukuze kuqinisekiswe ukuba igesi yokukhupha ingaqokelelwa ngokufanelekileyo. Ngokomzekelo, kwi-workshop enkulu ye-electroplating, indibaniselwano yee-hoods zendawo yokuqokelela kunye neenkqubo zokungenisa umoya jikelele zingasetyenziselwa ukubamba ngokubanzi igesi yokukhupha i-cyanide.

2. Utyando

• Ukususwa kothuli : Sebenzisa izixhobo zokususa uthuli ezifana nezihluzi zeengxowa okanye ii-electrostatic precipitators ukususa izinto ezincinci kwigesi yokukhupha umoya. Izinto ezincinci zinokuba neekhompawundi ze-cyanide kumphezulu wazo, kwaye ukuzisusa kwangaphambili kunokuphucula ukusebenza kakuhle konyango olulandelayo kwaye kuthintele umonakalo kwizixhobo zonyango.

• Ukususa i-Waxing kunye nokuSuswa koMswakamo : Ekubeni igesi yokukhupha umoya inokuba nomphunga wamanzi kunye nomphunga weoyile, sebenzisa izixhobo zokususa umphunga kunye nezisusa umswakama ukususa ezi zinto. Umphunga wamanzi unokuchaphazela ukusebenza kakuhle kwempendulo yeenkqubo zonyango ezilandelayo, kwaye umphunga weoyile unokuba nefuthe ekusebenzeni kwee-catalysts kunye nezifunxi.

3. Inkqubo engundoqo yoNyango

• Indlela yokufunxa imichiza

• Umgaqo : Sebenzisa izisombululo ze-alkaline ezifana ne-sodium hydroxide (NaOH) okanye i-calcium hydroxide (Ca(OH)₂) njengezifunxi. I-Cyanide kwi-exhaust gas isabela kwisisombululo se-alkaline ukwenza iityuwa ze-cyanide. Umzekelo, i-HCN isabela kwi-NaOH ukwenza i-Sodium Cyanide (NaCN), enokuyisusa ngempumelelo i-cyanide kwi-exhaust gas.

• Inkqubo : Igesi ephumayo ingena kwinqaba yokufunxa iikhemikhali, apho idibana nesisombululo se-alkaline esitshiziweyo ngendlela echasene nomsinga. Inqaba yokufunxa idla ngokuzaliswa zizinto zokupakisha ukwandisa indawo yoqhagamshelwano phakathi kwegesi nolwelo, nto leyo ephucula ukusebenza kakuhle kokufunxa.

• Indlela ye-Catalytic Oxidation

• Umgaqo : Phantsi kwesenzo se-catalyst, i-cyanide kwi-exhaust gas i-oxidized ibe yi-non-toxic Carbon dioxide (CO₂), amanzi (H₂O), kunye ne-nitrogen (N₂). Ii-catalysts eziqhelekileyo ziquka ii-precious metal catalysts (ezifana ne-platinum, i-palladium) kunye nee-metal oxide catalysts (ezifana ne-titanium dioxide, i-vanadium pentoxide).

• Inkqubo : Emva kokudlula kwinqaba yokufunxa iikhemikhali, igesi yokukhupha umoya ingena kwisixhobo sokufunxa i-catalytic oxidation. Esi sixhobo sixhotyiswe ngebhedi ye-catalyst, kwaye igesi yokukhupha umoya idlula kwibhedi ye-catalyst kubushushu obuthile kunye nesantya sendawo. I-catalyst ikhuthaza ukusabela kwe-oxidation ye-cyanide, inciphisa ubuthi bayo.

• Indlela yokufunxa emanzi

• Umgaqo : Sebenzisa inqaba yokufunxa emanzi ukutshiza isifunxi solwelo ukuze kufunxwe i-cyanide kwigesi yokukhupha umoya. Isifunxi sinokuba sisisombululo esikhethekileyo seekhemikhali esenziwe ngokweempawu ze-cyanide.

• Inkqubo : Igesi yokukhupha umoya ingena kwinqaba yokufunxa emanzi isuka ezantsi, kwaye into efunxa umoya itshizwa isuka phezulu. Ezi zimbini zidibene kwinqaba, kwaye i-cyanide kwigesi yokukhupha umoya ifunxwa yi-absorbent. Ulwelo olufunxayo emva koko luphathwa ngokwahlukeneyo ukuze kususwe i-cyanide.

• Indlela yoNyango lwebhayoloji

• Umgaqo : Ezinye iintsholongwane zinamandla okubola i-cyanide. Sebenzisa ezi ntsholongwane ukonakalisa i-cyanide kwigesi yokukhupha umoya kwindawo efanelekileyo.

• Inkqubo : Igesi yokukhupha umoya iqala ifumile ize ingene kwisixhobo sonyango lwebhayoloji. Esi sixhobo sinesithwali sebhayoloji apho iintsholongwane zinamathele khona. I-Cyanide kwigesi yokukhupha umoya ifunxwa yi-biofilm ize ibole ziintsholongwane zibe zizinto ezingenabungozi. Nangona kunjalo, le ndlela ifuna ulawulo olungqongqo lweemeko zokusingqongileyo ezifana nobushushu, i-pH, kunye nobonelelo lwezondlo ukuqinisekisa ukukhula okuqhelekileyo kunye nomsebenzi weentsholongwane.

4. Ukubeka iliso kunye nokukhutshwa

• Faka izixhobo zokubeka iliso kwi-intanethi kwindawo yokukhupha igesi yokukhupha ukuze uhlale ubeka iliso kugxininiso lwe-cyanide kunye nolunye ungcoliseko kwirhasi yokukhupha. Kuphela xa igesi yokukhupha idibana nemigangatho yelizwe kunye neyendawo yokukhupha inokuthi ikhutshwe emoyeni. Idatha yokubeka iliso kufuneka irekhodwe kwaye ixelwe rhoqo ukuqinisekisa ukuthotyelwa kokusingqongileyo.

Into yokuphonononga

Ishishini elithile le-electroplating libe neengxaki ezinzulu ngongcoliseko lwegesi ephuma kwicyanide ngexesha lenkqubo yokuvelisa. Ukusombulula le ngxaki, ishishini lamkele la manyathelo onyango alandelayo:

3. Unyango Oluphambili : Kwamkelwe indibaniselwano yeenkqubo zokufunxwa kweekhemikhali kunye neenkqubo zokufunxwa kweekhemikhali. Okokuqala, igesi yokukhupha umoya yangena kwinqaba yokufunxwa kweekhemikhali ezaliswe yisisombululo seNaOH ukususa uninzi lwe-cyanide. Emva koko, i-cyanide eseleyo yaphinda yafunxwa yaza yabola kwisixhobo sokufunxwa kweekhemikhali.

4. Ukubeka iliso : Ndifake inkqubo yokubeka iliso kwi-intanethi ukuqinisekisa ukuba igesi ephumayo ecociweyo iyahlangabezana nemigangatho yesizwe yokukhupha umbane.

Emva kokuphunyezwa kwala manyathelo, i-cyanide concentration kwi-exhaust gas yeshishini yehla kakhulu, ukunciphisa ngokufanelekileyo ukungcoliseka kwendalo kunye nokukhusela impilo yabasebenzi.

isiphelo
