3 Sieve ya Molecular
-
Kuchepa kwa Mowa mu Distillation Tower/Desiccant/Adsorbent/Hollow glass molecular sieve
Sieve ya molekyulu 3A, yomwe imadziwikanso kuti molecular sieve KA, yokhala ndi pobowo pafupifupi 3 angstroms, imatha kugwiritsidwa ntchito poyanika mpweya ndi zakumwa komanso kutaya madzi m'thupi la ma hydrocarbon.Amagwiritsidwanso ntchito kwambiri poyanika mafuta onse, mpweya wosweka, ethylene, propylene ndi mpweya wachilengedwe.
Mfundo yogwirira ntchito ya sieve ya maselo imagwirizana kwambiri ndi kukula kwa pore kwa masikelo a molekyulu, omwe ndi 0.3nm/0.4nm/0.5nm motsatana.Amatha kutsatsa mamolekyu a mpweya omwe ma molekyulu awo amakhala ochepa kuposa kukula kwa pore.Kukula kwa kukula kwa pore, kumapangitsanso mphamvu ya adsorption.Kukula kwa pore kumakhala kosiyana, ndipo zinthu zomwe zimasefedwa ndikuzilekanitsa ndizosiyananso.M'mawu osavuta, 3a molekyulu sieve imatha kutsatsa mamolekyu omwe ali pansi pa 0.3nm, 4a molecular sieve, ma molekyulu adsorbed ayeneranso kukhala osakwana 0.4nm, ndi 5a molecular sieve chimodzimodzi.Akagwiritsidwa ntchito ngati desiccant, sieve ya molekyulu imatha kuyamwa mpaka 22% ya kulemera kwake mu chinyezi.
