Akụkọ - Kedu ụzọ e si agwọ uzuzu graphite na elektrọd mkpofu?

1. Njikwa Isi Iyi na Teknụzụ Njide

Usoro Emechiri Emechi na Mkpuchi Ekpuchiri: Wụnye mkpuchi e mechiri emechi n'ebe dị mkpa maka imepụta uzuzu (dịka ọmụmaatụ, ịpịcha, nyocha, ibuga) jikọtara ya na nzacha akpa dị elu (dịka ọmụmaatụ, ndị na-anakọta uzuzu akpa electrostatic). Nke a na-ebelata mkpokọta mmepụta uzuzu site na 2,000–3,000 mg/m³ ruo mkpokọta mwepụta nke 20–30 mg/m³, na-enweta arụmọrụ iwepụ uzuzu 99%.
Ngwa Mwepụ Uzuzu Na-egbochi Mgbawa: Ebe ọ bụ na uzuzu graphite na-eduzi ihe na otú o si emetụta ọkụ, jiri ihe ndị na-anakọta uzuzu na-anaghị agbawa agbawa (dịka ọmụmaatụ, ihe ndị na-ekewapụ cyclone na ihe nzacha akpa na-anaghị agbawa agbawa) iji belata ihe egwu mgbawa mgbe ejikọtara ya na ihe ndị nwere ike ire ọkụ.
Sistemụ Nchịkọta Uzuzu Mmiri: Jiri ihe mmiri fesa mmiri mee ka uzuzu dajụọ, nke dabara adaba maka iji ngwaọrụ arụ ọrụ. Rịba ama: Hụ na ihe electrode kpọrọ nkụ (dịka ọmụmaatụ, 60–80°C n'ime oven convection maka otu awa) iji gbochie mmetọ mmanụ dielectric.

2. Njikwa Nhicha na Mwepụ Ikuku

Usoro Nchacha nke Ọtụtụ Ogbo: Jụụ ikuku ọkụ dị elu site na ihe na-agbanwe okpomọkụ, wee gafee ya n'usoro site na ihe nkesa cyclone (maka obere ihe ndị buru ibu), ihe nhicha alkaline (iji mee ka gas acidic ghara ịdị irè), na ụlọ elu nke na-eme ka carbon na-abanye n'ime ahụ (maka iwepụ VOC). Mwepụ ikpeazụ na-eme site na ihe na-eme ka ikuku dị mita 15, na-ahụ na e mere ya nke ọmaỤkpụrụ Mwepụ Ihe Mmetọ Ikuku maka Isi Izugbe(GB 16297-1996).
Nlekota na Nhazi Ntanetị: Wụnye ihe mmetụta maka ihe ndị dị n'ime ihe na mkpokọta VOC iji gbanwee paramita dịka pH ngwọta srubber na oge nnọchi carbon a na-arụ ọrụ, na-eme ka mkpokọta mwepụta dị n'okpuru 120 mg/m³.

3. Usoro Njikwa Enyemaka

Mmiri mmiri: Tinye ihe mgbochi uzuzu (dịka ọmụmaatụ, mmiri polyacrylamide) n'ime ọdọ mmiri ndị e ji ọla kọpa mee na ọdụ, na-eme ka mmiri dị n'elu ala ruo 6–8% iji belata uzuzu na-agba ọsọ.
Nlekọta Ngwaọrụ na Nchedo Ndị Ọrụ: Na-ehicha akpa nzacha mgbe niile, na-enyocha ihe mkpuchi ọkpọkọ, ma na-enye ndị ọrụ ihe nku ume N95 na uwe na-anaghị ekpuchi uzuzu iji belata ohere ọrụ.

1. Ọgwụgwọ anụ ahụ tupu oge eruo

Nhazi na Nhicha: Kewaa elektrọd dịka ụdị (dịka ọmụmaatụ, ike nkịtị, ike dị elu), wepụ ihe ndị na-adịghị ọcha n'elu mmanụ na ígwè, ma jiri igwe ultrasonic (ugboro 40 kHz) hichaa ya ruo nkeji 10-15.
Ịkụcha na Ịchọpụta: Jiri ihe e ji agbaji agba iji belata elektrọd ruo ihe ruru ≤50 mm, wee jiri ihe na-ama jijiji fụchie ya. Debe ihe ruru 5–50 mm maka mmepụta elektrọd ọhụrụ.

2. Ịdị ọcha na Mweghachi nke Kemịkalụ

Nhazi Grafit dị Elu: Kpoo ihe ndị dị n'ime ọkụ graphitization na 2,800–3,000°C ruo awa 4–6 iji wepụ ihe ndị na-adịghị mma (dịka ọmụmaatụ, sọlfọ, nitrogen), na-eme ka ọdịnaya carbon dị na ya dịkwuo elu ruo ≥99.5%.
Nchacha Acid maka iwepụ ihe na-adịghị ọcha: Tinye ihe ndị a gwepịara egwepịa n'ime 15–20% hydrochloric acid na okpomọkụ 80–90°C ruo awa abụọ iji wepụ aluminom, ígwè, na ihe ndị ọzọ na-adịghị ọcha n'ígwè. Mee ka nzacha ahụ dị n'ime mmiri tupu a wụpụ ya.

3. Imegharị ihe pụrụ iche nke Alloy Electrode

Nkewa nke Platinum-Iridium Elektrọd: Maka elektrọd ndị nwere platinum-iridium alloys, gbazee platinum na aqua regia (80°C ruo awa 3). Wepụta iridium site na electrolysis nnu agbazere agbaze (usoro NaCl-KCl na 700°C) ma mee ka ha abụọ dị ọcha ruo 99.99% site na iji agbaze mpaghara.
Mmeghari ohuru nke Electrode nke E ji Kọpa mee: Ghichaa ihe mkpofu elektrọd copper-graphite, kewapụ graphite (njupụta: 1.8–2.1 g/cm³) na ntụ ntụ kọpa (njupụta: 8.9 g/cm³) site na flotation, ma mee ka ntụ ntụ kọpa dị ọcha nke ukwuu site na electrolysis (njupụta ugbu a: 200 A/m²).

1. Ntụnyere Ọnụego na Uru

Nzacha Akpa: Ntinye ego mbụ: ~¥500,000; ọnụ ahịa ọrụ: ¥0.2/m³ nke gas ikuku. Dabara adaba maka nnukwu ụlọ ọrụ elektrọd graphite (olu ikuku ikuku kwa afọ ≥100,000 m³).
Sistemụ Nchịkọta Uzuzu Mmiri: Ntinye ego akụrụngwa: ¥200,000; ọnụ ahịa ngwọta dabere na mmiri: ¥0.5/ton nke mmiri mkpofu. Ọ dị mma maka obere ụlọ ọrụ mmepụta ihe.
Mmegharị Electrode nke ihe mkpofu: Tọn ọ bụla na-enweta graphite kilogram 850 (uru ¥3,000) na ọla kilogram 150 (uru ¥5,000), na-emepụta ¥8,000 na mkpokọta ego. Oge ịkwụghachi ego: afọ 1.5–2.

2. Ọmụmụ Ihe gbasara ụlọ ọrụ

Ụlọ Ọrụ Electrode Graphite Na-eduga: E tinyere usoro "静电袋式除尘器 (ihe nzacha akpa electrostatic) + ụlọ elu adsorption carbon activated", na-ebelata mwepụta nke ihe ndị na-adịghị mkpa site na 2,000 mg/m³ ruo 15 mg/m³ ma na-enweta 95% VOC. Ntaramahụhụ gburugburu ebe obibi kwa afọ belatara site na ¥2 nde.
Ụlọ Ọrụ Mmegharị Elektrọd Ahụike: Eweghachitela alloys platinum-iridium ruo 99.99% site na electrolysis nnu gbazere agbaze, nke a na-eji ozugbo eme ihe na pacemaker. Echekwara ¥1.2 nde kwa tọn nke elektrọd mkpofu na ọnụ ahịa ihe eji arụ ọrụ.

Ụkpụrụ Mwepụ: Soro iwu ndị aGraphite Industry Pollutant Discharge Standard(GB 31573-2015), na-enye iwu ka e wepụta ihe ndị na-anaghị emepụta ihe ruru 30 mg/m³ na VOC ≤100 mg/m³.
Ihe Mkpali Mweghachi Akụrụngwa: Gbaa mbọ ka a nabata nke aNkọwapụta Nkà na ụzụ maka imegharị ihe mkpofu graphite(GB/T 35164-2017) yana ihe mkpali ụtụ isi (dịka ọmụmaatụ, nkwụghachi VAT 70% maka ngwaahịa graphite emelitere).
Iwu Nchekwa: Soro Iwu NchekwaKoodu Nchekwa Mgbochi Mgbawa Uzuzu(GB 15577-2018), nke chọrọ ngwaọrụ enyemaka mgbawa (nrụgide: 0.01–0.02 MPa) na nyocha ala electrostatic oge niile maka sistemụ iwepụ uzuzu.
