I-Nernst N2035A ACID dewpoint analyzer

Ibanga lohlelo lokusebenza

I-Nernst N2035AI-ACID dewpoint analyzeriyithuluzi lokuqapha ngesikhathi sangempela ku-inthanethi izinga lokushisa le-asidi le-dewpoint ku-flue gas kubhayela nesithando sokushisa.

Ngokwezinga lokushisa elilinganisiwe le-acid dew point, izinga lokushisa legesi ephumayo le-boiler nesithando sokushisa lingalawulwa ngempumelelo. Yehlisa izinga lokushisa eliphansi le-sulfuric acid dew point corrosion of equipment. Thuthukisa ukusebenza kahle kokushisayo. Khulisa ukuphepha kokusebenza kubhayela futhi welule impilo yesevisi yemishini.

Izici zohlelo lokusebenza

Ngemuva kokusebenzisa i-Nernst N2035AI-ACID dewpoint analyzer(amazolo ane-asidi), ungakwazi ngokunembile ukwazi inani le-asidi lamazolo, okuqukethwe komoyampilo, umusi (% inani lomhwamuko wamanzi) noma iphuzu lamazolo (-50 °C ~ 100°C), okuqukethwe kwamanzi (g/kg) kanye nenani lomswakama RH i-flue gas ye-boiler kanye nesithando sokushisa.

Umsebenzisi angakwazi ukulawula izinga lokushisa legesi ephumayo ngaphakathi kwebanga elingaphezudlwana kwendawo yamazolo e-asidi yegesi ephumayo ngokuya ngokuboniswa kwethuluzi noma amasiginali amabili okukhiphayo we-4-20mA. Ukuze ugweme ukugqwala kwe-acid esezingeni eliphansi futhi kwandise ukuphepha kokusebenza kwe-boiler.

Umgomo wohlelo lokusebenza

Kuma-boilers wezimboni noma ama-boilers wezitshalo zamandla, ukucwenga kwe-petroleum kanye namabhizinisi amakhemikhali kanye neziko lokushisa. Izibaseli zezinto ezimbiwa phansi (igesi yemvelo, igesi eyomile yokuhlunga, amalahle, uwoyela omkhulu, njll.) ngokuvamile zisetshenziswa njengezibaseli.

Lawa mafutha aqukethe ngaphezulu noma ngaphansi kwenani elithile lesulfure, elizokhiqiza i-SO₂ngesikhathi sokushiswa kwe-peroxide. Ngenxa yokuba khona kwe-oxygen eyengeziwe ekamelweni elivuthayo, inani elincane le-SO₂iphinde ihlangane ne-oxygen yakhe i-SO₃, Fe₂O₃futhi V₂O₅ngaphansi kwezimo zomoya ezeqile ezivamile. (i-flue gas kanye nensimbi evuthayo iqukethe le ngxenye).

Cishe i-1 ~ 3% yazo zonke i-SO₂iguqulelwa ku-SO₃. SO₃I-gas ku-high-temperature flue gas ayigqwali izinsimbi, kodwa lapho izinga lokushisa le-flue gas lehla ngaphansi kuka-400 ° C, SO₃izohlangana nomhwamuko ukuze ikhiqize umhwamuko we-sulfuric acid.

Ifomula yokusabela imi kanje:

SO₃+ H₂O ——— H₂SO₄

Lapho isitimu se-sulfuric acid sijiya endaweni yokushisisa ngasemsileni wesithando somlilo, izinga lokushisa eliphansi le-sulfuric acid dew point corrosion kuyokwenzeka.

Ngesikhathi esifanayo, uketshezi lwe-sulfuric acid olufingqiwe endaweni yokushisa esezingeni eliphansi nalo luzonamathela othulini lwegesi ephumayo ukuze kwakhe umlotha onamathelayo okungelula ukuwususa. Isiteshi segesi se-flue sivinjiwe noma sivinjiwe, futhi ukumelana kuyanda, ukuze kwandiswe ukusetshenziswa kwamandla kwe-fan yokusalungiswa eyenziwe. Ukugqwala nokuvinjwa komlotha kuzobeka engcupheni isimo sokusebenza sendawo yokushisisa kubhayela. Njengoba i-flue gas iqukethe kokubili i-SO₃kanye nomhwamuko wamanzi, bazokhiqiza i-H₂SO₄umhwamuko, okuholela ekwandeni kwephuzu lamazolo e-asidi egesi ye-flue. Lapho izinga lokushisa legesi ephuma ku-flue liphansi kunezinga lokushisa le-asidi lamazolo e-flue gas, i-H₂SO₄i-steam izonamathela ku-flue kanye nesishintshi sokushisa ukuze yenze u-H₂SO₄isisombululo. Kuphinde kulimaze okokusebenza, okuholela ekuvuzeni kwesishintshi sokushisa kanye nokulimala komtshingo.

Kumadivayisi asekelayo wesithando sokushisa noma ibhayili, ukusetshenziswa kwamandla kwe-flue kanye nesishintshi sokushisa kubala cishe u-50% wengqikithi yamandla asetshenziswa idivayisi. Ukushisa kwegesi ephumayo kuthinta ukusebenza kahle kokushisa okushisayo kwezithando zokushisa kanye nama-boilers. Ukuphakama kwezinga lokushisa lokukhipha umoya, kunciphisa ukusebenza kahle kokushisa. Njalo ngo-10°C enyuka izinga lokushisa legesi ephumayo, ukusebenza kahle kwe-thermal kuzokwehla cishe ngo-1%. Uma izinga lokushisa legesi yokukhipha umoya liphansi kunezinga lokushisa le-asidi lamazolo egesi ephumayo, lizodala ukugqwala kwemishini futhi libangele izingozi zokuphepha ekusebenzeni kwezithando zokushisa namabhayela.

Izinga lokushisa elikahle lokukhipha umoya wesithando sokushisisa nebhayela kufanele libe phezulu kancane kunezinga lokushisa elineasidi lamazolo egesi ephumayo. Ngakho-ke, ukunquma izinga lokushisa lamazolo e-asidi yezithando zokushisa nama-boilers kuyisihluthulelo sokuthuthukisa ukusebenza kahle kokushisa nokunciphisa izingozi zokuphepha zokusebenza.
