I-Environmental Technology Exhaust Gas Treatment

Incazelo emfushane:

Igesi yokuphelelwa yigesi yokuphekela igesi iyingozi empilweni yomuntu nasendaweni yokuphila, nephunga legesi yokuphelelwa yi-coating akonakaliswa yi-soling ye-coating kanye nokubola kwefilimu lapho yomiswa, iningi le-organic hydrocarbons.


Incazelo Yomkhiqizo

Igesi yokukhipha igesi yokukhipha igesi iyingozi empilweni yomuntu kanye nemvelo ephilayo, futhi iphunga legesi yokukhipha igesi elinamathelayo liyi-solvent ye-coating kanye nokubola kwefilimu lapho isomiswa, ikakhulukazi ama-hydrocarbon ephilayo.Kunezinhlobo ezintathu zokunukubezeka komoya egesini ephumayo evela ekudwebeni, okuyilezi
1) ingaba i-organic solvent ye-photochemical smog <isibonelo: i-xylene, i-methyl isobutyl ketone, isophorone, njll.
2) iphunga likapende onukayo, imikhiqizo yokubola okushisayo nemikhiqizo yokusabela (njenge-triethylamine, i-acrolein, i-formaldehyde, njll.)
3) upende wokufafaza uthuli.

Isimiso Sokusebenza

1. Ukuphuma kwegumbi lokufafaza ukuze kugcinwe indawo yokusebenza yegumbi lokufutha, isivinini sokungenisa umoya kufanele silawulwe ngaphakathi kwebanga (0.25 ~ 1) m/s ngokuhambisana nezinhlinzeko zomthetho wokuphepha kanye nezempilo.Ukuphela kwegumbi elijwayelekile lokufafaza ngevolumu yomoya enkulu, ukugcwaliseka kwe-solvent vapor kuphansi kakhulu (ingxenye yayo yevolumu icishe ibe ngo-10-3% ~ 2 × 10 - '%).Ngaphezu kwalokho, ukuqeda amandla egumbi lesifutho futhi kuqukethe ingxenye yenkungu yokupenda ekhiqizwe ngokufafaza.
Usayizi wezinhlayiyana zalolu thuli (amaconsi enkungu ye-lacquer) cishe (20 ~ 200) μm noma ngaphezulu, awukho umoya omkhulu endizela kude, futhi ubangele ingozi yomphakathi eseduze, kodwa futhi ube yisithiyo sokumosha ukwelashwa kwegesi, lezi kufanele zikhokhelwe. ukunaka.
2. Umsebenzi wokukhipha umoya ekamelweni okomisa umoya ekamelweni ukwenza i-coating emdwebeni, ukomisa noma ukomiswa ngenkani ngaphambili, ukuze ingxenye ye-solvent efilimini i-volatilization ebushelelezi kanye nokwakheka kwefilimu enhle, ngokuvamile isandiso se-solvent. Inqubo yegumbi lokupenda, kulokhu kuqothuka kuqukethe kuphela i-solvent vapor, futhi cishe kungekho bust wist wist.
3. I-exhaust ephuma egumbini lokomisa Igesi ekhishwayo ephuma egumbini lokomisa, okuhlanganisa nokuphuma kwesistimu kapende kanye nesistimu kaphethiloli.Owokuqala uqukethe i-solvent eyinsalela kufilimu enamathelayo engahwamuki egunjini lesifutho nasegunjini lokomisa, ingxenye yezingxenye eziguquguqukayo njenge-plasticizer noma i-resin monomer, imikhiqizo yokubola okushisayo, imikhiqizo yokusabela.Lesi sakamuva sisetshenziswa njengomthombo wokushisa wamagesi okukhipha uphethiloli.Ukubunjwa kwayo kuyahlukahluka ngophethiloli, njengokushisa kwamafutha anzima, aqukethe inani elikhulu lesulfure ekukhiqizeni igesi ye-sulfite, lapho izinga lokushisa lomlilo liphansi, ukulungiswa kokusebenza nokugcinwa okungalungile nokuphathwa, ngenxa yokuvutha okungaphelele nomusi.Ukusetshenziswa kukaphethiloli wegesi, yize izindleko zikaphethiloli ziphezulu futhi igesi yokuphekela i-combustion icacile, kunezindleko eziphansi zemishini, ukulungiswa okulula, izinzuzo eziphakeme ezisebenza kahle.Lapho kusetshenziswa ugesi nomusi njengemithombo yokushisa egumbini lokumisa, amagesi aqede ohlelweni lwamafutha awabhekwanga.
