3-(4-chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole 2-(chloromethyl)-3-methylpyridinehydrochloride 1-(2-bromo-4-methylphenyl)ethanone 3-chloroisoquinoline-4-carbonitrile 5,8-dichloropyrido[3,2-d]pyridazine 2-bromomalononitrile 2-(4-(bromomethyl)phenyl)benzo[d]thiazole 1-(bromomethyl)-3-methoxy-2-nitrobenzene 6-bromo-1H-[1,2,3]triazolo[4,5-b]pyridine 4-iodo-2-((trimethylsilyloxy)methyl)thiazole 6-iodoimidazo[1,2-a]pyridine-3-carbonitrile 2-(4-chlorophenyl)-2-morpholinoacetonitrile 4-chloro-7H-pyrrolo[2,3-d]pyrimidine 4-chloroisothiazole 5-bromo-6-chloro-1H-indole 7-chloro-3H-imidazo[4,5-b]pyridine ethyl3-(4-formylphenyl)propanoate 2,3-dibromobenzaldehyde 1-(5H-chromeno[2,3-b]pyridin-7-yl)ethanone 5H-chromeno[2,3-b]pyridin-5-one 3-chloroisoquinoline-4-carbaldehyde (E)-2-(3-oxoprop-1-enyl)benzaldehyde methyl4-formyl-3-nitrobenzoate 5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 1-methylbicyclo[4.1.0]heptan-3-one 3-nitro-4-(trifluoromethoxy)benzaldehyde 2-hydroxyquinoline-6-carbaldehyde 2-nitro-3-(trifluoromethyl)benzaldehyde 1-(2-fluoro-4-methoxyphenyl)propan-2-one tert-butyl3-fluoro-4-oxopiperidine-1-carboxylate tert-butyl3-oxopropylcarbamate 2,2-dimethylcyclohexanone 9H-carbazole-3-carbaldehyde N,N-dimethyl-2-oxoacetamide 2-methylpent-4-yn-2-ol 3-tert-butyl-4-hydroxybenzonitrile 4-bromo-2-tert-butylphenol 1,3-dibutoxypropan-2-ol methyl4-hydroxyquinoline-6-carboxylate methyl3-cyano-4-hydroxybenzoate 4-chloro-6-methoxyquinolin-7-ol 3,4-dihydro-2H-benzo[b][1,4]oxazin-7-ol 2-(2-aminothiazol-5-yl)ethanolhydrochloride (R)-ethyl2-chloropropanoate (S)-4-amino-5-(4,4-dimethylcyclohexylamino)-5-oxopentanoicacid (1s,4s)-4-hydroxycyclohexanecarboxylicacid (S)-2-(tetrahydrofuran-3-yloxy)aceticacid (1S,4R)-1-methyl-4-(prop-1-en-2-yl)cyclohex-2-enol (R)-4-(hydroxymethyl)oxazolidin-2-one (S)-4-(hydroxymethyl)oxazolidin-2-one 化工資訊 日前，重慶旗能電鋁有限公司大修槽1053#順利通過技改，采用的新型高位分區(qū)集氣結(jié)構(gòu)，實現(xiàn)了電解鋁生產(chǎn)中所產(chǎn)生的氟化氫氣體得到有效收集。
據(jù)國家實驗室認可的檢測中心檢測顯示，1053#槽與傳統(tǒng)的電解槽下部V型煙道集氣槽1054#槽對比，1053#槽煙氣中氟含量為44.51mg/m3，而1054#槽煙氣中氟含量為24.79mg/m3，煙氣中的氟含量通過凈化系統(tǒng)再次循環(huán)利用率可達98.5%以上。由此可見，采用高位分區(qū)集氣結(jié)構(gòu)的1053#電解槽在氟鹽的再利用上比傳統(tǒng)集氣結(jié)構(gòu)的1054#槽要高79.5%，可以有效降低噸鋁氟化鋁消耗約3.8公斤。
重慶旗能電鋁采用420kA大型預(yù)焙電解槽，傳統(tǒng)的電解槽下部縱向V型集氣結(jié)構(gòu)很難滿足大型電解槽的集氣要求，而采用高位分區(qū)集氣結(jié)構(gòu)設(shè)計更為科學(xué)合理。因電解鋁產(chǎn)生的氟化氫氣體密度輕、易上升，高位集氣能有效捕捉產(chǎn)生的氟化氫氣體，而電解槽下部V型煙道不能全部收集飄浮在槽內(nèi)中、上部的氟化氫氣體，導(dǎo)致部分有害物通過天窗無組織散排。通過改造后的大型鋁電解槽，采用高位分區(qū)集氣技術(shù)能解決以上問題，達到節(jié)能、降耗、環(huán)保的作用。
