Kuyini ukuhanjiswa kwe-pneumatic?
I-pneumatic conveying ukuthuthwa kwezinto eziqinile ngobuningi ngepayipi ngokusebenzisa ukugeleza komoya noma enye igesi.... Ukuthuthwa kwe-pneumatic kungakhiwa njengokucindezela okuhle noma uhlelo lwe-vacuum.
Ukudlulisa impushana yomoya kusebenzisa amandla okugeleza komoya.I-pneumatic conveying ibizwa nangokuthi uhlelo lokudlulisa umoya noma uhlelo lokudlulisa umoya.Ukusetshenziswa okukhethekile kobuchwepheshe be-fluidization ukuthutha izinto ze-granular ngendlela yokugeleza komoya ngepayipi elivaliwe.Isakhiwo sedivayisi yokudlulisa umoya ilula futhi kulula ukuyisebenzisa.Ingasetshenziselwa ukuthutha ovundlile, mpo noma oblique.Phakathi nenqubo yokuthutha, imisebenzi engokwenyama efana nokushisisa, ukupholisa, ukuhlukaniswa kokugeleza okomile, noma eminye imisebenzi yamakhemikhali nakho kungenziwa ngesikhathi esifanayo.
Ngokuvumelana nokuminyana kwezinhlayiya zokuhamba ngamapayipi, ezokuthutha ze-pneumatic zihlukaniswe zibe:
1. I-Dilute phase transportation: okuqukethwe okuqinile kungaphansi kuka-100kg/m3 noma isilinganiso esiqinile-kuya-gas (isilinganiso sokugeleza kwesisindo phakathi kwevolumu yokuthutha eqinile kanye nokusetshenziswa kwegesi okuhambisanayo) ngu-0.1-25.Isivinini segesi esisebenzayo siphezulu uma kuqhathaniswa (cishe ngo-1830ms, ngokuya ngengcindezi yegesi esemgqeni, ihlukaniswe ngohlobo lokudonsa kanye nohlobo lokulethwa kwengcindezi. Ingcindezi esepayipini iphansi kunomfutho womoya, ukuzincela ngokwakho, kodwa kufanele Ibanga lifushane, ingcindezi esephayiphini lokugcina iphakeme kunomfutho womoya, futhi ukukhishwa kulula, futhi kungathuthwa ibanga elide, kodwa impushana. izinhlayiya kufanele zithunyelwe epayipini lokucindezela ngumuntu ophakelayo.
2. Ukuthutha kwesigaba esiminyene: inqubo yokuthutha lapho okuqukethwe okuqinile kungaphezu kuka-100kg/m3 noma isilinganiso segesi eqinile singaphezu kuka-25. Isivinini somoya esisebenzayo siphansi, futhi umfutho womoya ophezulu usetshenziselwa ukwakha uhlelo lokulethwa komoya. .Izikhawu ngezikhathi ithangi eligcwele umoya uhlobo lokuhamba kwesigaba esiminyene.Faka izinhlayiya ethangini lokucindezela ngamaqoqo, bese uzifaka umoya ukuze uzikhulule.Lapho ingcindezi ethangini ifinyelela ukucindezela okuthile, vula i-valve yokukhipha bese ushaya izinhlayiya epayipini elihambisayo lokuhamba.Ukudlulisa i-Pulse ukudlulisa umoya ocindezelwe ethangini eliphansi ukuze kuxegiswe impahla;okunye ukugeleza komkhathi ocindezelwe ukushaya kwe-pulse nge-frequency ye-2040min-1 kushaywe ku-inlet yepayipi lokuphakelayo, kwenze amakholomu amancane ahlelwe ngokushintshana kanye nezingxenye ezincane zepayipi Ikholomu yomoya isebenzisa ukucindezela komkhathi ukuze iqhubekele phambili.Ezokuthutha zesigaba esiminyene zinamandla amakhulu ezokuthutha, zingacindezelwa ibanga elide, umonakalo wezinto ezibonakalayo kanye nokugqokwa kokucushwa kuncane, futhi ukusetshenziswa kwamandla nakho kuncane.Lapho kwenziwa ukuthuthwa kwesigaba se-dilute ohlelweni lokuthutha lwamapayipi ovundlile, isivinini segesi kufanele sibe phezulu ukuze izinhlayiya zikhishwe futhi zimiswe ekugelezeni komoya.Lapho ukhetha ukuhanjiswa kwesigaba sokuxubha noma ukudlulisa isigaba esiminyene, kuklanywe ngokuya ngokukhipha okuphumayo kanye nokusebenza kwempahla eyimpushana.
