Anti tshuaj lom txoj cai ntawm tshuaj lom lim tank

Cov khoom ntim hauv lub tank lim lim yog tsim los ntawm cov txheej txheem adsorbent thiab lim txheej. Ntawm lawv, txheej adsorption yog siv los lim cov pa phem, thiab lim txheej siv los lim cov teeb meem sol.

(1) Anti tshuaj lom txoj cai ntawm adsorbent txheej

Cov txheej txheem adsorbent ntawm lub npog ntsej muag tau txais cov pa roj carbon activated nrog catalyst lossis tshuaj adsorbent. Cov pa roj carbon activated no feem ntau hu ua kuzi activated carbon lossis impregnated carbon, los yog tshuaj lom pov thawj carbon lossis catalytic carbon. Impregnated activated carbon ua tiav lub hom phiaj ntawm kev tiv thaiv kab mob los ntawm peb txoj haujlwm hauv qab no.

① Lub cev adsorption. Lub cev adsorption yog tshwm sim los ntawm kev sib nrig sib attraction ntawm cov adsorbate thiab cov adsorbent molecules. Cov adsorbed molecules tswj lawv cov khoom siv tshuaj qub, tsis muaj kev xaiv, thiab muaj qhov nrawm nrawm thiab desorption ceev. Piv txwv li, cov pa roj carbon activated muaj lub cev adsorption ntawm cov pa phem xws li sarin, mustard gas, chlorine, thiab lwm yam.

② Chemisorption. Chemisorption yog tshwm sim los ntawm adsorption ntawm adsorbate thiab adsorbent molecules los ntawm lub zog zoo ib yam li cov saw hlau. Cov adsorbate thiab adsorbent tsim cov khoom sib xyaw ua ke, uas yog xaiv thiab feem ntau tsis tuaj yeem thim rov qab.

③ Catalysis. Catalysis yog hais txog cov tshuaj tiv thaiv catalytic ntawm qee cov tshuaj lom vapors uas nyuaj rau lub cev thiab tshuaj lom neeg adsorbed, uas tuaj yeem txhim kho qhov ceev ntawm cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv catalytic ntawm impregnated carbon feem ntau yog oxygen thiab dej hauv huab cua. Nyob rau hauv qhov kev txiav txim ntawm lub catalyst, nws reacts nrog cov tshuaj lom neeg sawv cev.

(2) Antivirus txoj cai ntawm lim txheej

Cov txheej lim tshwj xeeb yog siv los lim cov teeb meem aerosols. Cov pa luam yeeb (cov khoom tsis zoo), pos huab (cov kua ua kua), cov plua plav hluav taws xob thiab cov khoom uas muaj cov kab mob thiab cov kab mob hu ua aerosols. Cov txheej txheem pom ntawm cov teeb meem aerosol los ntawm cov txheej lim dej muaj me ntsis ua rau cov khoom siv tshuaj lom neeg ntawm aerosol hais, tab sis feem ntau nrog lawv lub cev thiab cov yam ntxwv ntawm kev txav.

Cov txheej txheem ntawm filtering aerosols. Tam sim no, feem ntau siv iav fiber ntau lim txheej yog tsim los ntawm ntau txheej ntawm crisscross fiber ntau daim phiaj. Thaum aerosol hais dhau los, lawv yuav muaj sijhawm los tiv tauj cov fiber ntau thiab raug thaiv.
