Ukuhlafuna nge-Phosgenekuyinqubo ebalulekile yokususa le gesi eyingozi ekukhishweni kwegesi ezimbonini, ukuvikela abasebenzi, imiphakathi, kanye nemvelo ngenkathi kuqinisekiswa ukulandelwa kwemithetho eqinile njengaleyo evela kwi-Environmental Protection Agency (EPA).
Okubalulekile kule nqubo yilokhuimitha yokuhlushwa koketshezi lokuhlafuna, idivayisi eqapha ukuhlushwa koketshezi oluhlafunwayo njenge-sodium hydroxide (NaOH) ukuze igcine ukumuncwa okuhle. Ngokuvimbela izinkinga ezifana nokungaxutshwa kahle noma ukuxutshwa ngokweqile, lawa mamitha athuthukisa ukusebenza kweizinhlelo zokuhlanza igesi.
I-Lonnmeter, umkhiqizi ohamba phambili nonolwazi lwezinzwa zenqubo ezihlakaniphile, iyazikhandla ekukhiqizeni izinzwa zenqubo yezimboni eziqinile ukuze ithuthukise izinga lokuzenzakalela komugqa wokukhiqiza ohlanganisiwe.umkhiqizi we-isocyanate,umenzi we-polycarbonate, noma ukuphathaindawo yokuphatha imfucuza, imitha yokuhlushwa eqondile yeLonnmeter iyizixazululo ezisetshenziswa kakhulu ukuthuthukisa ukusebenza kahle nokunciphisa izindleko.
Ukuqonda Ukuhlafuna Igesi Ye-Phosgene
Ukuhlafuna kuhilela ukudlulisa igesi equkethe i-phosgene nge-umbhoshongo wokuhlanza igesinoma uhlelo lapho uketshezi, ngokuvamile i-NaOH, luqeda noma lumunca igesi, luyiguqule ibe yizakhi eziphephile njenge-sodium carbonate (Na₂CO₃) kanye ne-sodium chloride (NaCl). Ukusebenza kahle kwale nqubo kuncike ekugcineni ukuhlushwa okulungile koketshezi lokuhlikihla, okuyilaphoamamitha okuhlushwa koketshezi lokuhlafunabadlala indima ebalulekile.
Kungani Kudingeka Ukuhlafuna I-Phosgene Gas?
Ukuhlafuna ngegesi ye-phosgenekubalulekile ngezizathu eziningana:
Ukuphepha:Ukuchayeka kwe-phosgene ekugxilweni okuphansi njengo-3–5 ppm kungabangela ukucasuka kokuphefumula, kuyilapho amazinga aphezulu eholela ekuvuvukeni kwamaphaphu. Ukuhlafuna kuvimbela ukuchayeka kwabasebenzi kanye nomphakathi.
Ukuthobela Imithetho:Imithetho eqinile, njengaleyo evela ku-EPA, iyalela ukuqapha nokulawula ukukhishwa kwe-phosgene ukuze kuvikelwe imvelo.
Ukuvikelwa Kwemvelo:Ukukhishwa kwe-phosgene okungalawulwa kungangcolisa umoya namanzi, kulimaze imvelo.
Ukuqhubeka Kokusebenza:Ukuhlikihla okuphumelelayo kuvimbela ukwehluleka kwesistimu, okuqinisekisa ukukhiqizwa okungaphazamiseki.
Izihlanzi ze-Caustic Ukuhlanza Igesi Ye-Phosgene
Izihlanzi ze-Caustic zisetshenziswa kabanziukuhlafuna nge-phosgenengenxa yobulula nokusebenza kahle kwazo. Zisebenza ngokudlulisa igesi ye-phosgene kukholomu egcwele egcwele i-NaOH, esabela ekwakheni i-Na₂CO₃, i-NaCl, namanzi. Izinto ezibalulekile okufanele uzicabangele zifaka:
Ukuqapha Ukuhlushwa:Ukuhlushwa kwe-NaOH kumele kugcinwe ngaphakathi kwe-5–20 wt% ukuqinisekisa ukumuncwa okuphumelelayo.
Ukuphathwa Kokushisa:Ukusabela kwe-exothermic kudala ukushisa, okudinga uhlelo lokupholisa.
Ukwakheka Kosawoti:Amazinga aphezulu e-NaCl noma e-Na₂CO₃ (5–30 wt%) angabangela ukwakheka kwamakristalu, okudinga ukususwa kukasawoti ukuze kuvinjelwe ukuvaleka kwesistimu.
Ukweqiwa kwemisebenzi:Amaphampu okusekelayo kanye nezinsiza zikagesi eziphuthumayo ziqinisekisa ukusebenza okuqhubekayo.
Indima Yokuhlanza Amamitha Okuhlushwa Koketshezi
Zisebenza Kanjani?
Amamitha okuhlushwa koketshezilinganisa amazinga e-NaOH, NaCl, kanye ne-Na₂CO₃ ngesikhathi sangempela, uqinisekise ukumuncwa okuhle kakhuluizinhlelo zokuhlanza igesi. Kusetshenziswa ubuchwepheshe be-ultrasonic, lawa mamitha ahlaziya ijubane le-sonicmanufacuhlakangu-d Lku-onni-meterukunquma ukujiya.
Inzwa yokucwilisa yemitha ivame ukufakwa kumapayipi e-DN 80 phakathi kwe-scrubber nethangi lokuvuselela, ihlanganiswe nezinhlelo zokulawula ukuze kulungiswe ngokuzenzakalelayo.
Izicelo ku-Phosgene Scrubbing
Ukuqapha Okuqondile:Iqinisekisa ukwakheka koketshezi okuhambisanayo ngesikhathi sokuhlikihla.
Ukulawulwa Kwenqubo:Ilungisa ngokuzenzakalelayo isilinganiso se-NaOH noma ukususwa kosawoti ukuze kuvinjelwe ukwakheka kwekristalu.
Ukuphathwa Kwemfucuza:Ihlola okuqukethwe kwamakhemikhali okusele ukuze kusetshenziswe kabusha noma kulahlwe.
Izinzuzo Zokuhlafuna Ukulinganisa Ukuhlushwa Koketshezi
Ukuphepha Okuthuthukisiwe
Ukulinganisa ukuhlushwa koketshezikuqinisekisa ukuthi uketshezi lokuhlikihla luhlala lusebenza kahle, kunciphisa ingozi yokuphuma kwe-phosgene. Lokhu kubalulekile ekuvikeleni abasebenzi kanye nemiphakathi ekuchayekeni kule gesi enobuthi obukhulu.
Ukuthobela Imithetho
Izimboni kumele zilandele imithetho eqinile, njengaleyo evela ku-EPA kanye ne-OSHA. Amamitha okuhlushwa ahlinzeka ngedatha enembile, yesikhathi sangempela yokubika ukukhishwa komoya, ukwenza kube lula ukuhlolwa kwezimali kanye nokugwema izinhlawulo.
Ukusebenza Kahle Kokusebenza
Ukuqapha ngesikhathi sangempela kuvimbela ukungasebenzi kahle okubangelwa ukugcwala okungalungile, kunciphisa isikhathi sokungasebenzi kwesistimu nezidingo zokulungisa. Isibonelo, isitshalo samakhemikhali songe ihora eli-1 nsuku zonke ezindlekweni zabasebenzi ngokuzenzakalelayo ukuhlolwa kokugcwala.
Ukonga Izindleko
Ngokwenza ngcono ukusetshenziswa kwe-NaOH nokuvimbela ukuncishiswa kwe-d d ngokweqile,amamitha okuhlushwa koketshezi lokuhlafunaukunciphisa izindleko zokulahlwa kwemfucuza kanye nokugcwalisa kabusha, okunikeza ukonga okukhulu kwemisebenzi ebiza kakhulu.
Izici Zobuchwepheshe Nokuhlanganiswa
Ukufakwa kanye Nokusebenza
Amamitha okuhlushwa koketshezizifakwa emapayipini noma emathangini, kusetshenziswa izinzwa eziqinile ezenziwe ngezinto eziqinile ukuze zimelane nezimo ezigqwalayo. Zihlanganiswa nezinhlelo ze-PLC/DCS zokulawula okuzenzakalelayo, ziqinisekisa ukulungiswa kwesikhathi sangempela ukuze kulondolozwe ukugxila okufanele.
Izidingo Zokunakekela
Ukulinganisa:Ukuhlolwa ngezikhathi ezithile ukuqinisekisa ukunemba.
Ukuhlanza Izinzwa:Kuvimbela ukungcola okuvela ekuqongeleleni usawoti.
Ukuhlolwa Kwesistimu:Ukuhlolwa njalo kwezinto zikagesi kanye nokuxhumeka.
Izitayela Zesikhathi Esizayo Zokuhlafuna Igesi Ye-Phosgene
Ukuzenzakalela:Izinhlelo eziqhutshwa yi-AI zizobikezela ukugxila koketshezi okuhle kakhulu ngokusekelwe kudatha yesikhathi sangempela.
Izinzwa Ezihlakaniphile:Izokala imingcele eyengeziwe efana ne-pH kanye namazinga okungcola.
Ukusimama:Uketshezi lokuhlanza olusekelwe kwi-bio lungadinga ukuqapha ngokucophelela ukuhluzwa.
Ukuguquka Kwemithetho:Izindinganiso eziqinile zokukhishwa komoya zizokwandisa isidingo semikhiqizo esezingeni eliphezuluukulinganisa ukuhlushwa koketshezi.
Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa)
Kungani kudingeka ukuhlafuna ngegesi ye-phosgene?
Ukuhlafuna nge-PhosgeneKubalulekile ukususa igesi enobuthi ye-phosgene ekukhishweni kwegesi, ukuvikela abasebenzi, imiphakathi, kanye nemvelo ngenkathi kuqinisekiswa ukulandelwa kwemithetho efana naleyo evela ku-EPA.
I-caustic scrubber isebenza kanjani ku-phosgene?
I-caustic scrubber isebenzisa i-NaOH ukuqeda i-phosgene, yakha i-Na₂CO₃, i-NaCl, namanzi.Amamitha okuhlushwa koketsheziqapha amazinga e-NaOH ukuqinisekisa ukumuncwa okuphumelelayo.
Zisetshenziswa kuphi izihlanzi zegesi ze-phosgene?
Izinhlelo zokuhlanza igesizisetshenziswa ezitshalweni zamakhemikhali (ama-isocyanates, ama-polycarbonate), ukukhiqizwa kwamakhemikhali emithi kanye nezolimo, kanye nezindawo zokuphatha imfucuza eziphatha amakhemikhali ane-chlorine.
Ingabe kukhona ukukhathazeka ngokuphepha ngezinhlelo zokuhlanza igesi ye-phosgene?
Yebo, izinhlelo kumele zisebenze ngokuqhubekayo ngama-backups ukuvimbela ukuvuza kwe-phosgene.Ukulinganisa ukuhlushwa koketshezikuqinisekisa ukuthembeka kwesistimu, futhi abaqhubi badinga i-PPE nokuqeqeshwa.
Ukuhlanza amamitha okuhlushwa koketshezi kuthuthukisa kanjani ukusebenza kahle?
Banikeza idatha yesikhathi sangempela ukuvimbela ukuncishiswa ngokweqile noma okunganele, ukunciphisa isikhathi sokungasebenzi kanye nokwenza ngconoukuhlanzwa kwamagesiukuze kongiwe izindleko futhi kulandelwe imithetho.
Amamitha okuhlushwa koketsheziziyashintshaukuhlafuna nge-phosgenengokuqinisekisa ukugcwala koketshezi okufanele, ukuthuthukisa ukuphepha, ukuthobela imithetho, kanye nokusebenza kahle. Sicela uxhumane nonjiniyela beLonnmeter ukuze bahlole izimo zokusebenza kwakho futhi batuse izinzwa zenqubo ezifanele.
Ungavumeli ukuhlafuna okungafanele kubeke engcupheni ukuphepha noma ukuthobela imithetho yesikhungo sakho. Xhumana nathi namuhla ukuze uhlole ukuthi indlela yethu yokuhlanzaamamitha okuhlushwa koketshezi lokuhlafunaingaphakamisa eyakhoumbhoshongo wokuhlanza igesiukusebenza.
