Kodi Chowumitsira Chozizira N'chiyani?
Chowumitsira mufiriji chimachotsa madzi kuzinthu zomwe zimawonongeka kuti zisungidwe, kukulitsa moyo wake wa alumali komanso / kapena kuti zikhale zosavuta kuyenda.Zowumitsira kuzizira zimagwira ntchito pozizira zinthuzo, kenako kuchepetsa kuthamanga ndi kuwonjezera kutentha kuti madzi oundana azitha kusintha kukhala nthunzi (sublimate).
Chowumitsira chowumitsa madzi chimagwira ntchito m'magawo atatu:
1. Kuzizira
2. Kuyanika Kwambiri (Sublimation)
3. Kuyanika Kwambiri (Adsorption)
Kuyanika kozizira koyenera kumatha kuchepetsa nthawi yowumitsa ndi 30%.
Gawo 1: Gawo Lozizira
Iyi ndi gawo lovuta kwambiri.Zowumitsira kuzizira zimagwiritsa ntchito njira zosiyanasiyana zowumitsa zinthu.
Kuziziritsa kungathe kuchitika mufiriji, bafa lozizira kwambiri (mufiriji wa zipolopolo), kapena pa shelefu ya chowumitsira.
· Chowumitsira kuzizira chimaziziritsa zinthu zomwe zili pansi pa katatu kuti zitsimikizire kuti sublimation, osati kusungunuka, idzachitika.Izi zimasunga mawonekedwe akuthupi azinthu.
Choumitsira kuzizira bwino chimawumitsa madzi oundana akuluakulu, omwe amatha kupangidwa ndi kuzizira pang'onopang'ono kapena kuzizira.Komabe, ndi zinthu zachilengedwe, makhiristo akakula kwambiri amatha kuthyola makoma a cell, ndipo izi zimapangitsa kuti aziwumitsa amaundana ochepa kwambiri.Pofuna kupewa izi, kuzizira kumachitika mofulumira.
• Pazinthu zomwe zimakonda kugwa, annealing itha kugwiritsidwa ntchito.Izi zimaphatikizapo kuzizira kwambiri, ndikukweza kutentha kwa mankhwala kuti makhiristo akule.
Gawo 2: Kuyanika Kwambiri (Kutsitsa)
· Gawo lachiwiri ndi kuyanika koyamba (sublimation), momwe kuthamanga kumatsikira ndikutentha kumawonjezeredwa pazinthuzo kuti madzi azitha kutsika.
· Chowumitsira chowumitsira chowumitsira chowumitsa chiwongolero chimathamanga kwambiri.Chowumitsira chowumitsira kuzizira chimapereka malo oti nthunzi wamadzi umamatire ndi kulimba.Condenser imatetezanso pampu ya vacuum ku nthunzi yamadzi.
· Pafupifupi 95% ya madzi muzinthu amachotsedwa mu gawoli.
· Kuyanika koyambirira kumatha kukhala pang'onopang'ono.Kutentha kwambiri kumatha kusintha kapangidwe kazinthu.
Gawo 3: Kuyanika Kwambiri (Adsorption)
Gawo lomalizali ndi kuyanika kwachiwiri (adsorption), pomwe mamolekyu amadzi omangidwa ndi ionically amachotsedwa.
· Mwa kukweza kutentha kwambiri kuposa gawo loyamba lowumitsa, zomangira zimasweka pakati pa zinthu ndi mamolekyu amadzi.
· Kuundana zouma zouma kukhala ndi porous dongosolo.
· Chowumitsira kuzizira chikamaliza ntchito yake, vacuum imatha kuthyoledwa ndi mpweya wa inert zinthuzo zisanasindikizidwe.
· Zipangizo zambiri zitha kuuma mpaka 1-5% chinyezi chotsalira.
Mavuto Owumitsa Owumitsa Kuti Muwapewe:
Kutenthetsa chinthucho kutentha kwambiri kungayambitse kusungunuka kapena kugwa kwazinthu
Kuchulukirachulukira kwa condenser komwe kumachitika chifukwa cha nthunzi wochuluka womwe ukugunda pa condenser.
o Kupanga nthunzi wambiri
o Pamwamba kwambiri
o Malo ochepa kwambiri a condenser
o Kusakwanira firiji
· Kutsekeka kwa nthunzi - mpweya umapangidwa mothamanga kwambiri kuposa momwe ungadutse pa doko la nthunzi, doko pakati pa chipinda chopangira zinthu ndi condenser, ndikupanga kuchuluka kwamphamvu kwachipinda.
