Njirimara nke Electroplating Cyanide Exhaust Gas

1. Nnukwu nsi: Ngwakọta Cyanide, karịsịa HCN, na-egbu egbu nke ukwuu. Ọbụlagodi na mkpokọta dị ala, ha nwere ike imerụ ahụ mmadụ. Ikuku gas iyuzuchasị nke nwere cyanide nwere ike ibute mgbaàmà dịka isi ọwụwa, isi ọwụwa, mkpụmkpụ ume, na n'ọnọdụ siri ike, ọ nwere ike ibute ndụ egwu.

2. Ntụkwasị obi dị ala mana mmetụta mkpokọta: N'ozuzu, ntinye nke electroplating cyanide iyuzucha gas dị ntakịrị, ma n'ihi ọgbọ na-aga n'ihu n'oge usoro electroplating, ọ bụrụ na a naghị agwọ ya nke ọma, nchịkọta nchịkọta ga-eme ka mmetọ dị 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

• Wepụ ustjá: Jiri akụrụngwa na-ewepu uzuzu dị ka ihe nzacha akpa ma ọ bụ ihe ọkụ eletrik iji wepụ ihe dị n'ime ikuku ikuku. Ihe dị iche iche nwere ike iburu ogige cyanide n'elu ya, na iwepụ ha tupu oge eruo nwere ike imeziwanye arụmọrụ nke ọgwụgwọ na-esote ma gbochie mmebi nke akụrụngwa ọgwụgwọ.

• Mwepụ na mkpochapụ na iru mmiri: Ebe ọ bụ na ikuku iyuzucha nwere ike ịnwe uzuoku mmiri na alụlụ mmanụ, jiri ngwaọrụ na-ekpochapụ ihe na ihe na-ekpochapụ ihe ndị a iji wepụ ihe ndị a. Uzuoku mmiri nwere ike imetụta mmeghachi omume mmeghachi omume nke usoro ọgwụgwọ na-esote, na alụlụ mmanụ nwekwara ike inwe mmetụta na arụmọrụ nke ihe na-akpali akpali na ihe na-amị amị.

3. Usoro ọgwụgwọ isi

• Usoro absorption nke kemịkalụ

• Ụkpụrụ: Jiri ihe ngwọta nke alkaline dị ka sodium hydroxide (NaOH) ma ọ bụ calcium hydroxide (Ca (OH) ₂) dị ka ihe ndị na-eri ihe. Cyanide dị n'ime ikuku ikuku na-emeghachi omume na ngwọta alkaline iji mepụta nnu cyanide. Dịka ọmụmaatụ, HCN na-emeghachi omume na NaOH iji mepụta sodium cyanide (NaCN), nke nwere ike wepụ cyanide n'ụzọ dị irè na gas iyuzucha.

• usoro: The iyuzucha gas na-abanye kemịkalụ absorption ụlọ elu, ebe ọ na-akpọtụrụ ndị sprayed alkaline ngwọta n'ụzọ countercurrent. Ụlọ elu absorption na-ejupụtakarị na ihe nkwakọba ihe iji mee ka mpaghara kọntaktị dị n'etiti gas na mmiri mmiri na-eme ka ọ dịkwuo mma.

• Usoro Oxidation Catalytic

• ỤkpụrụN'okpuru ọrụ nke ihe na-akpali akpali, a na-eme ka cyanide dị na gas ikuku na-ekupụ ghara ịdị njọ 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 oxide (dịka titanium dioxide, vanadium pentoxide).

• usoro: Mgbe ị gafechara ụlọ elu nke kemịkalụ, ikuku ikuku na-abanye na ngwaọrụ oxidation catalytic. Ngwaọrụ ahụ nwere akwa akwa akwa, na ikuku iyuzucha na-agafe n'ihe ndina na-eme ka ọ dị ọkụ na ụfọdụ okpomọkụ na oghere oghere. Ihe na-akpali akpali na-akwalite mmeghachi omume oxidation nke cyanide, na-ebelata nsị ya.

• Ụzọ absorption mmiri

• Ụkpụrụ: Jiri ụlọ elu nnabata mmiri na-efesa ihe na-amịkọrọ mmiri iji banye cyanide n'ime ikuku ikuku. The absorbent nwere ike ịbụ ihe pụrụ iche kemịkalụ ngwọta emepụtara dị ka e ji mara cyanide.

• usoro: Igwe na-ekpocha ọkụ na-abanye n'ụlọ elu nke mmiri mmiri na-abanye n'ime ala, a na-efesakwa ihe ahụ site n'elu. Ha abụọ nọ na kọntaktị na ụlọ elu ahụ, na cyanide dị na gas na-ekpochapụ na-etinye uche na ya. A na-edozi mmiri mmiri a na-etinye n'ime ya iche iche iji wepụ cyanide.

• Usoro ọgwụgwọ ndu

• Ụkpụrụ: Ụfọdụ microorganisms nwere ike ire ere nke cyanide. Jiri microorganisms ndị a mebie cyanide n'ime ikuku ikuku na gburugburu ebe kwesịrị ekwesị.

• usoro: A na-ebu ụzọ mee ka ikuku iyuzucha ikuku wee banye na ngwaọrụ ọgwụgwọ nje. Ngwa ahụ nwere ihe na-ebu biofilm nke ejikọtara microorganisms na ya. A na-etinye Cyanide dị n'ime gas na-ekpochapụ site na biofilm wee mebie ya site na microorganisms ka ọ bụrụ ihe na-adịghị egbu egbu. Agbanyeghị, usoro a chọrọ njikwa siri ike nke ọnọdụ gburugburu ebe obibi dị ka ọnọdụ okpomọkụ, pH, na nri nri iji hụ na uto na ọrụ nke microorganisms na-adị.

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. Mkpokọta gas na-ekpochapụ: Awụnyere mkpuchi mkpuchi gas na-arụ ọrụ dị elu n'elu tankị electroplating iji hụ na a na-anakọta ihe karịrị 95% nke ikuku gas.

2. Esemokwu: Hazie usoro iwepụ uzuzu na ikpo ọkụ iji wepụ ihe na-adịghị mma na ikuku mmiri na gas na-ekpochapụ nke ọma.

3. Isi ọgwụgwọ: Nabata ngwakọta nke nnabata kemịkalụ na usoro oxidation catalytic. Nke mbụ, ikuku na-ekpocha ọkụ batara n'ụlọ elu nnabata kemịkalụ jupụtara na ngwọta NaOH iji wepụ ọtụtụ n'ime cyanide. Mgbe ahụ, cyanide fọdụrụnụ bụ oxidized ọzọ wee mebie na ngwaọrụ oxidation catalytic.

4. Monitoring: Awụnyere usoro nleba anya n'ịntanetị iji hụ na gas iyuzuchacha a na-edozi zutere ụkpụrụ ikuku nke 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.
