Desiccants ni ibintu bikurura ubuhehere cyangwa amazi. Ibi birashobora gukorwa hakoreshejwe inzira ebyiri zitandukanye:
Ubushuhe bwamamajwe kumubiri; iyi nzira yitwa adsorption
Ubushuhe burahambiriwe; iyi nzira yitwa kwinjiza
Ubwoko busanzwe bwa desiccant bukora alumina, molekile ya molekile, alumina silica gel
Adsorbent (igipimo cya adsorption igipimo cyo kugereranya ingano)
Ingano ya Adsorption:
Alumina silika gel> silika gel> molekile ya sikeli> ikora alumina.
igipimo cya adsorption: icyuma cya molekile> aluminasilika gel> silika gel> ikora alumina.
Tubwire ibisabwa byo kurinda ubushuhe, kandi tuzaguha inama ikwiye. Niba ibicuruzwa byawe cyangwa ibikoresho bipakiye bisaba urwego rwo hasi cyane rwubushuhe, nibyiza gukoresha amashanyarazi ya molekile. Niba ibicuruzwa byawe bidafite ubushyuhe buke, silika gel desiccant izabikora.
① Adsorbent mumazi, imbaraga zo kwikuramo ziragabanuka, kuzura ntabwo byoroshye
Sisitemu yingutu zingana ntabwo cyangwa ihagaritswe, ingaruka ni nini cyane
Gukoresha inkoni yuzuza inkoni, bigira ingaruka kumbaraga zo kwikuramo ibicuruzwa
Alumina ikora: 160 ° C-190 ° C.
Icyuma cya molekulari: 200 ° C-250 ° C.
Amazi ya alumina silika irwanya amazi: 120 ° C-150 ° C.
Inzira yo kubara: kuzuza QTY = Kuzuza Umubare * Ubwinshi bwinshi
Kurugero, imashini imwe yashizeho = 2M3 * 700kg / M3 ＝ 1400kg
JZ-CMS4N yibanda kuri azote ni 240 M3 / toni hashingiwe kuri 99.5% N2 yera, Rero imwe yashizeho N2 ubushobozi bwo gusohora ni = 1.4 * 240 = 336 M3 / h / gushiraho
Uburyo bwa PSA O2: adsorption ikanda, desorption yo mu kirere, Turashobora gukoresha JZ-OI9, JZ-OI5
Uburyo bwa VPSA O2: adsorption yo mu kirere, vacuum desorption, Turashobora gukoresha ubwoko bwa JZ-OI5 na JZ-OIL
Ifu ya zeolite ikora ikurura amazi arenze muri sisitemu ya PU, mugihe defoamer irwanya antifoaming kandi ntabwo ikurura amazi. Ihame rya defoamer nugusenya impirimbanyi zifatika zifatika, kugirango imyenge ifashe. ifu ya zeolite ikora ikurura amazi kandi ikoreshwa mugucamo uburinganire hagati yamazi nicyiciro cyamavuta kugirango defoam.
