Malangizo pa Kugula Sieves Molecular

Momwe Sieve ya Molecular imagwirira ntchito

Zomwe zimagwiritsidwa ntchito mu sieve ya ma molekyulu a mafakitale zimakhala ndi ma pores ang'onoang'ono. Zinthu zina zikakumana ndi sieve ya mamolekyulu, mamolekyu omwe ali oyenerera kulowa m’mabowo amaoneka ngati adsorbed. Mamolekyu omwe ndi aakulu kwambiri kuti asagwirizane nawo sangatero. Sieve za mamolekyulu zimagwira ntchito pamlingo wa microscopic, chifukwa chake kukula kwake kumayesedwa mu angstroms. Miyezo ya pore 3Å ndi 4Å idzawonetsa madzi pamene zazikulu zimachotsa ma hydrocarbons akuluakulu.

Zida za Sieve ya Molecular

M'lingaliro lenileni la sayansi, zinthu zambiri zachilengedwe za desiccant desiccant dehumidifiers monga laimu, dongo ndi silika gelisi zimagwiranso ntchito posefa mamolekyu a nthunzi yamadzi, koma ma sieve amalonda amapangidwa ndi aluminosilicates opangidwa ndi crystalline. Mosiyana ndi ma desiccants omwe amapezeka m'chilengedwe, kuwongolera kukula kwa pore panthawi yopanga kumapanga mawonekedwe osankha.

Ubwino wa Sieves Molecular

Sieves ya ma molekyulu imakonda madzi mofulumira kuposa zowumitsira mpweya zina za desiccant ndipo zimatha kuchepetsa chinyezi kumagulu otsika kwambiri omwe amafanana ndi gel osakaniza. Zimakhalanso zogwira mtima kwambiri kuposa ma desiccants achilengedwe omwe amapitilira kutentha kwachipinda. Akagwiritsidwa ntchito moyenera, amatha kuchepetsa mamolekyu amadzi otsika ngati 1ppm m'zotengera zapadera kapena mpaka 10% chinyezi chapamapaketi.

Kuipa kwa Sieves Molecular

Mitengo ndi yapamwamba kuposa mitundu ina ya desiccant dehumidification; komabe, masefa a mamolekyu amakhalanso aluso kwambiri. Ndalama zenizeni pa unit ndi mtengo womaliza zidzadalira zinthu zina monga kuchuluka kwa madzi kuti achotsedwe komanso mulingo wouma wofunikira. Masefa a mamolekyulu, ngakhale amavomerezedwa kuti agwiritsidwe ntchito ndi mankhwala ku Europe, sanavomerezedwe ndi FDA pazakudya kapena mankhwala ku US.

Masefa a mamolekyulu ali ndi mphamvu yabwino kwambiri komanso amakondera, ngakhale pa kutentha kokwera. Ndiwo desiccant okha omwe amasankha kukula kwa maselo.

Kubadwanso Kwatsopano ndi Kugwiritsiridwanso Ntchito Kwa Ma Sieves a Molecular

Ngakhale kuti masefa ena a ma molekyulu omwe amachotsa mowa ndi ma hydrocarbon onunkhira amagwiritsira ntchito mphamvu kuti apangitsenso sieve, masikelo a molekyulu omwe amagwiritsidwa ntchito popanga madzi nthawi zambiri amapangidwanso ndi kutentha. Pazinthu zambiri zamafakitale, kutentha uku kumachokera ku 250 ° mpaka 450 ° F, mofanana ndi kutentha kwa kuphika kwa uvuni wamba wakukhitchini.
