Nrog rau kev sib tw ua lag luam hnyav zuj zus thiab kev txhim kho ntawm qib kev noj qab haus huv, muaj kev loj hlob ntawm kev tswj xyuas kev ruaj ntseg ntawm cov dej qab zib los txhim kho cov khoom zoo thiab yog li ua kom muaj kev sib tw ua lag luam. Oxygen "yog tus yeeb ncuab ntawm kev ntim cov dej haus, yog li kev tswj cov pa oxygen yog qhov tseem ceeb tshaj plaws hauv kev lag luam dej haus niaj hnub tswj kom zoo. Cov ntsiab lus ntawm cov pa oxygen yaj yog ze ze rau ib feem ntawm cov pa oxygen hauv huab cua thiab qhov kub ntawm cov dej. Cov xwm txheej ntuj, cov pa oxygen hauv huab cua tsis hloov pauv ntau, yog li dej kub yog qhov tseem ceeb, qhov kub ntawm cov dej qis dua, cov ntsiab lus ntawm cov pa oxygen hauv cov dej ntau dua 20 degree thiab 100kPa, yaj oxygen hauv dej ntshiab. yog kwv yees li 9mg/L. Qee cov organic compounds undergo biodegradation nyob rau hauv qhov kev txiav txim ntawm cov kab mob aerobic, uas yuav tsum tau noj cov pa yaj hauv dej.Qhov kev puas tsuaj ntawm cov pa yaj: 1. Hloov cov tsw ntawm cov dej haus thiab cuam tshuam rau lawv cov xim; 2, Txo cov pa oxygen. tsw ruaj khov thiab tsis muaj roj ntsha ruaj khov ntawm cov dej haus; 3, Thaum qhov kub thiab txias, qhov tshwm sim ntawm "lub raj mis vau" tshwm sim vim kev siv cov pa oxygen. ib yam khoom, inexhaustible thiab tsis muaj xim, tsis muaj tshuaj lom, thiab tsw ntxhiab inert gas. Qhov ceev yog 1.2506kg / m, lub melting point yog -209 86 degree , thiab lub boiling point yog -195.8 degree . Nws yog me ntsis soluble nyob rau hauv dej thiab ethanol thiab tsis nquag rau tshuaj lom neeg nrog rau lwm yam tshuaj. Gaseous nitrogen tsis tso cov tshuaj seem thaum siv rau hauv cov txheej txheem khaws cia, yog li nws feem ntau siv rau kev khaws khoom noj. Kev siv nitrogen raws li kev khaws cia rau npias, cawv, thiab kua txiv hmab txiv ntoo yog tam sim no ib qho kev nkag siab zoo los ntawm cov tuam txhab ntawm cov khoom zoo li no. Nws tuaj yeem ua kom huv ntawm cov khoom zoo li no ntau qhov tseeb, nrog lub neej txee ntev dua, thiab tsim nyog rau cov saj ntawm cov neeg siv khoom niaj hnub no. Kev sib piv ntawm nitrogen thiab carbon dioxide Tam sim no, ntau lub teb chaws npias, cawv, thiab kua txiv hmab txiv ntoo cov khoom lag luam tseem siv cov pa roj carbon dioxide ua cov pa roj. Tom qab kev taw qhia ntawm nitrogen preservation thev naus laus zis, ntau qhov zoo yog qhov zoo heev piv rau carbon dioxide. 1, Tsawg tus nqi khiav lag luam, cov khoom siv tsis muaj nqi, siv huab cua los ua cov khoom siv raw thiab siv lub zog viav vias adsorption kom cais cov nitrogen los ntawm huab cua, qhov txheeb ze peev nyiaj tsawg dua carbon dioxide; 2, Cov roj ntau lawm ceev ceev, thiab nws tuaj yeem qhib thiab siv tau txhua lub sijhawm. Nees nkaum feeb ua ntej siv, tsim nyog roj tuaj yeem tsim los ntawm kev tig lub tshuab; 3, High degree ntawm automation, siv Siemens computer programming, tsis tas yuav muaj kev mob siab rau cov neeg ua haujlwm saib xyuas, thiab tuav thaj chaw me me; 4, Kev nqis peev ib zaug, kev saib xyuas yooj yim. Kev sib xyaw ntawm nitrogen hauv cov dej haus tuaj yeem ua rau cov pa oxygen yaj hauv cov kua dej los nag, thiab cov pa oxygen hauv cov kua dej tuaj yeem ua rau lawv saj thiab ua rau lawv lub neej ntev. Nyob rau hauv ib txoj kev hu ua "stirring" (cov roj compressed stirs cov kua los ntawm ib tug tshuaj tsuag), gaseous nitrogen yog nkag mus rau hauv cov kua thaum lub sij hawm kev kho mob. Cov npuas no tshem tawm cov pa oxygen los tiv thaiv oxidation, kev noj nyiaj txiag thiab fading ntawm carbonate dawb dej qab zib (txiv hmab txiv ntoo, tshuaj yej thiab mis nyuj). Cia peb qhia luv luv PSA nitrogen generator, uas yog lub siab viav vias adsorption nitrogen generator.
