Ụzọ ọgwụgwọ maka Electroplating Cyanide Exhaust Gas

Okwu Mmalite

N'ime ụlọ ọrụ electroplating , a na-ejikarị cyanides eme ihe dị ka ihe mgbakwunye electroplating dị mkpa. Ha nwere ike ime ka mma na arụmọrụ nke oyi akwa electroplating dịkwuo mma nke ukwuu. Agbanyeghị, n'oge usoro electroplating, a na-emepụta gas exhaust nwere cyanide , nke nwere ihe ndị na-egbu egbu dị ka hydrogen cyanide (HCN). Nke a na-etinye nnukwu ihe egwu nye gburugburu ebe obibi na ahụike mmadụ. Ya mere, ọgwụgwọ dị irè nke gas exhaust cyanide electroplating dị oke mkpa.

Isi mmalite nke Electroplating Cyanide Exhaust Gas

1. Tankị Electroplating : N'oge electroplating, n'ihi mgbanwe nke electrolyte na gas nke mmeghachi omume electrolytic na-emepụta, a na-ewepụta gas ikuku nke nwere cyanide. Dịka ọmụmaatụ, na electroplating cyanide nke ọlaedo na ọlaọcha, ngwakọta cyanide dị na ngwọta plating ga-agbanwe n'okpuru ọrụ nke okpomọkụ na ọkụ eletrik.

2. Usoro Nhicha : Mgbe ejiri ihe nhicha dị na electroplating hichaa ihe ndị e ji arụ ọrụ ahụ , obere cyanides ga-emebi emebi. Ọ bụrụgodị na mkpokọta cyanides dị na ihe nhicha ahụ adịghị obere, mkpokọta ogologo oge na mmebi nwere ike ibute nsogbu mmetọ.

3. Ọgwụgwọ Mmiri Mkpofu : Ọ bụrụ na ọgwụgwọ mmiri mkpofu elektrọnik adịghị mma, gas cyanide nwere ike ịpụ. N'ime usoro ọgwụgwọ mmiri mkpofu nwere cyanide, ọ bụrụ na a naghị achịkwa ọnọdụ mmeghachi omume nke ọma, mmebi nke cyanides nwere ike imepụta gas HCN ma banye n'ikuku.

4. Ngwa Ndị Na-enyere Aka : Ngwa dịka sistemu ikuku na ngwaọrụ ndị na-ekpo ọkụ nwekwara ike ịkpata obere gas ikuku na-ekupụ n'oge a na-arụ ọrụ. Ọ bụ ezie na ọnụọgụ ya pere mpe, ebe ọ bụ na e nwere nnukwu nsị nke cyanide, a pụghị ileghara ya anya.

Njirimara nke Electroplating Cyanide Exhaust Gas

1. Nnukwu Nsí : Ihe ndị dị na Cyanide, karịsịa HCN, na-egbu egbu nke ukwuu. Ọbụna n'ime obere mkpokọta, ha nwere ike imebi ahụ mmadụ. Iku ume gas nke nwere cyanide nwere ike ibute mgbaàmà dịka isi ọwụwa, isi ọwụwa, iku ume mkpụmkpụ, na n'ọnọdụ ndị siri ike, ọ nwere ike ibute ndụ.

2. Mmetụta Dị Ala Mana Ọ Na-agbakọta : N'ozuzu, oke ikuku cyanide nke na-ekupụ ihe na-eme ka electroplating dị obere, mana n'ihi mmepụta na-aga n'ihu n'oge usoro electroplating, ọ bụrụ na ejighị ya nke ọma, mmetụta ahụ ga-ebute mmetọ ogologo oge na gburugburu ebe obibi.

Usoro ọgwụgwọ nke Electroplating Cyanide Exhaust Gas

1. Mkpokọta gas na-ekpochapụ

• Wụnye mkpuchi mkpuchi gas ma ọ bụ ngwaọrụ nchịkọta ndị ọzọ na ebe nrụpụta gas na-ekpochapụ. Ekwesịrị ịmepụta ngwaọrụ nchịkọta ndị a dịka usoro mmepụta na nhazi nke kpọmkwem iji hụ na enwere ike ịnakọta gas na-ekpochapụ nke ọma. Dịka ọmụmaatụ, na nnukwu ụlọ ọrụ electroplating, enwere ike iji ngwakọta nke mkpuchi mkpokọta mpaghara yana usoro ikuku ikuku zuru oke iji weghara gas iyuzucha nke nwere cyanide.

2. Esemokwu

• Iwepụ Uzuzu : Jiri ngwa iwepụ uzuzu dịka nzacha akpa ma ọ bụ ihe na-eme ka mmiri ghara ịdị n'ime gas ikuku. Ihe nwere ike ibu ihe ndị dị n'ime ya, iwepụ ha tupu oge eruo nwere ike ime ka ọgwụgwọ ahụ ka mma ma gbochie mmebi nke akụrụngwa ọgwụgwọ.

• Iwepụ wax na mmiri mmiri : Ebe ọ bụ na gas ikuku nwere ike ịnwe uzuoku mmiri na uzuoku mmanụ, jiri ngwaọrụ mwepụ ihe na ihe ndị na-eme ka mmiri dị jụụ wepụ ihe ndị a. Uzuoku mmiri nwere ike imetụta arụmọrụ mmeghachi omume nke usoro ọgwụgwọ na-esote, uzuoku mmanụ nwekwara ike inwe mmetụta na arụmọrụ nke ihe na-akpali akpali na ihe ndị na-amịkọrọ ihe.

3. Usoro ọgwụgwọ isi

• Usoro absorption nke kemịkalụ

• Ụkpụrụ : Jiri ihe ngwọta alkaline dịka sodium hydroxide (NaOH) ma ọ bụ calcium hydroxide (Ca(OH)₂) dị ka ihe ndị na-amịkọrọ ihe. Cyanide dị na gas ikuku na-emeghachi omume na ihe ngwọta alkaline iji mepụta nnu cyanide. Dịka ọmụmaatụ, HCN na-emeghachi omume na NaOH iji mepụta Sodium Cyanide (NaCN), nke nwere ike iwepụ cyanide nke ọma na gas ikuku ikuku.

• Usoro : Gas ikuku na-abanye n'ụlọ elu mmiri kemịkalụ, ebe ọ na-ezute mmiri alkaline a gbanyere n'ụzọ mgbochi ọkụ. A na-ejikarị ihe ndị e ji ekpuchi ụlọ elu mmiri ahụ ejupụta ebe a na-etinye gas na mmiri mmiri iji mee ka ebe dị n'etiti gas na mmiri ahụ dịkwuo mma, na-eme ka arụmọrụ mmiri dịkwuo mma.

• Usoro Oxidation Catalytic

• Ụkpụrụ : N'okpuru ọrụ nke ihe na-akpali akpali, a na-eme ka cyanide dị n'ime gas ikuku na-ekupụ ghọọ Carbon dioxide (CO₂), mmiri (H₂O), na nitrogen (N₂). Ihe ndị na-akpali akpali a na-ahụkarị gụnyere ihe na-akpali akpali ígwè dị oké ọnụ ahịa (dịka platinum, palladium) na ihe na-akpali akpali ígwè (dịka titanium dioxide, vanadium pentoxide).

• Usoro : Mgbe ọ gafere ụlọ elu nke na-amịkọrọ kemịkalụ, gas ikuku na-abanye na ngwaọrụ ikuku ọkụ catalytic. Ngwaọrụ a nwere ihe mkpuchi ihe mkpali, gas ikuku ọkụ na-agafekwa n'elu ihe mkpuchi ihe mkpali na okpomọkụ na ọsọ oghere ụfọdụ. Ihe mkpali ahụ na-akwalite mmeghachi omume ikuku ọkụ nke cyanide, na-ebelata nsị ya.

• Ụzọ absorption mmiri

• Ụkpụrụ : Jiri ụlọ elu mmiri na-amịkọrọ mmiri fesa ihe na-amịkọrọ mmiri iji na-amịkọrọ cyanide n'ime gas na-amịkọrọ mmiri. Ihe na-amịkọrọ mmiri nwere ike ịbụ ihe ngwọta kemịkalụ pụrụ iche nke a na-emepụta dịka njirimara nke cyanide si dị.

• Usoro : Mmanụ ikuku na-esi n'ala abanye n'ụlọ elu mmiri na-amịkọrọ mmiri, a na-efesakwa ihe na-amịkọrọ mmiri site n'elu. Ha abụọ na-emetụ aka n'ụlọ elu ahụ, ihe na-amịkọrọ mmiri na-amịkọrọ mmiri na-amịkọrọ mmiri na-amịkọrọ mmiri. A na-agwọkwa mmiri ahụ a mịrị amị iche iche iji wepụ ihe na-amịkọrọ mmiri.

• Usoro ọgwụgwọ ndu

• Ụkpụrụ : Ụfọdụ nje ndị dị ndụ nwere ike ịgbaze cyanide. Jiri nje ndị a gbazere cyanide n'ime ikuku anwụrụ ọkụ n'ebe kwesịrị ekwesị.

• Usoro : A na-ebu ụzọ mee ka ikuku anwụrụ ọkụ ahụ dị mmiri mmiri wee banye na ngwaọrụ ọgwụgwọ bayọlọji. Ngwaọrụ ahụ nwere ihe na-ebu biofilm nke a na-etinye obere nje. Cyanide dị na gas anwụrụ ọkụ na-abanye na biofilm ma gbazee site na obere nje ndị na-adịghị egbu egbu. Agbanyeghị, usoro a chọrọ njikwa siri ike nke ọnọdụ gburugburu ebe obibi dịka okpomọkụ, pH, na inye nri iji hụ na obere nje ndị ahụ na-eto ma na-arụ ọrụ nke ọma.

4. Nleba anya na mwepụ

• Wụnye akụrụngwa nleba anya n'ịntanetị n'ọdụ ụgbọ mmiri na-ekpochapụ gas ka ị na-enyocha mgbe niile na mkpokọta cyanide na mmetọ ndị ọzọ na gas na-ekpochapụ. Naanị mgbe gas na-ekpochapụ na-ezute ụkpụrụ ikuku nke mba na nke mpaghara nwere ike ịwụpụ ya na ikuku. Ekwesịrị ịdekọ data nleba anya na ịkọ akụkọ mgbe niile iji hụ na nnabata gburugburu ebe obibi.

Ileba Ọmụmụ

Otu ụlọ ọrụ electroplating nwere nnukwu nsogbu na mmetọ ikuku nke cyanide nwere n'oge usoro mmepụta. Iji dozie nsogbu a, ụlọ ọrụ ahụ nakweere usoro ọgwụgwọ ndị a:

1. Nchịkọta Gas Ikuku : E tinyere ihe mkpuchi nchịkọta gas dị elu n'elu tankị electroplating iji hụ na e chịkọtara ihe karịrị 95% nke gas ikuku.

2. Ọgwụgwọ tupu oge eruo : Hazie sistemụ iwepụ uzuzu na iwepụ mmiri mmiri iji wepụ ihe ndị dị n'ime ya na uzu mmiri dị n'ime gas ikuku.

3. Ọgwụgwọ Isi : A nabatala njikọta nke usoro nnabata kemịkalụ na usoro oxidation catalytic. Nke mbụ, gas ikuku na-apụ apụ banyere n'ụlọ elu nnabata kemịkalụ juputara na mmiri NaOH iji wepụ ọtụtụ cyanide ahụ. Mgbe ahụ, a na-eme ka cyanide fọdụrụnụ gbazee ma gbazee na ngwaọrụ oxidation catalytic.

4. Nlekota : E tinyere sistemụ nlekota n'ịntanetị iji hụ na ikuku anwụrụ ọkụ a gwọrọ ruru ụkpụrụ mwepụta mba.

Mgbe mmejuputa usoro ndị a gasịrị, ntinye nke cyanide na gas na-ekpochapụ nke ụlọ ọrụ ahụ belatara nke ukwuu, na-ebelata mmetọ gburugburu ebe obibi nke ọma na ichebe ahụike nke ndị ọrụ.

mmechi

Ọgwụgwọ nke electroplating cyanide iyuzucha gas bụ ihe dị mkpa iji chebe gburugburu ebe obibi na ahụike mmadụ na ụlọ ọrụ electroplating. Site na ịnakwere mkpokọta gas na-ekpochapụ kwesịrị ekwesị, ọgwụgwọ mbụ, ọgwụgwọ bụ isi, na nleba anya na usoro mwepụ, enwere ike belata ntinye nke cyanide na gas iyuzucha nke ọma iji mezuo ihe ndị a chọrọ maka nchekwa gburugburu ebe obibi. N'ọdịnihu, na-aga n'ihu na nkwalite nke ihe nchekwa gburugburu ebe obibi chọrọ, ụlọ ọrụ electroplating kwesịrị ịnọgide na-ebuli ma na-emepụta usoro ọgwụgwọ ikuku gas iji nweta mmepe na-adigide.
