Ukuba kukho iziphene kwisihluzo se-hepa kunye nofakelo lwaso, njengemingxuma emincinci kwisihluzo ngokwayo okanye ukuqhekeka okuncinci okubangelwa kufakelo olukhululekileyo, umphumo ojoliswe kuyo wokucoca awuyi kufezekiswa.Ke ngoko, emva kokufaka okanye ukutshintshwa kwe-hepa filter, kufuneka wenze uvavanyo lokuvuza kwisihluzo kunye noqhagamshelo lofakelo.
1. Injongo kunye nobungakanani bokubona ukuvuza:
Injongo yokukhangela: Ngokuvavanya ukuvuza kwesihluzi se-hepa, fumana iziphene zesihluzo se-hepa kunye nofakelo lwaso, ukuze uthathe amanyathelo okulungisa.
Uluhlu lokufumanisa: indawo ecocekileyo, ibhentshi yomsebenzi we-laminar kunye ne-hepa filter kwizixhobo, njl.
2. Indlela yokufumanisa ukuvuza:
Eyona ndlela isetyenziswa ngokuqhelekileyo yindlela ye-DOP yokukhangela ukuvuza (oko kukuthi, ukusebenzisa isinyibilikisi se-DOP njengomthombo wothuli kunye nokusebenza nge-aerosol photometer ukukhangela ukuvuza).Indlela yokukhangela i-particle particle counter scanning ingasetyenziselwa ukukhangela iindawo ezivuzayo (oko kukuthi, ukusebenzisa uthuli olusemoyeni njengomthombo wothuli nokusebenza ngesixhobo sokubala samasuntswana ukukhangela iindawo ezivuzayo. ukuvuza).
Nangona kunjalo, ekubeni i-particle counter reading is a cumulative reading, ayincedi ukuskena kwaye isantya sokuhlola sicotha;Ukongeza, kwicala elinyukayo lesihluzo se-hepa phantsi kovavanyo, ukugxilwa kothuli lwe-atmospheric luhlala luphantsi, kwaye umsi owongezelelweyo uyafuneka ukuze kubonwe lula ukuvuza.Indlela yokubala yamasuntswana isetyenziselwa ukukhangela iindawo ezivuzayo.Indlela ye-DOP inokwenza nje ezi ntsilelo, ke ngoku indlela ye-DOP isetyenziswa ngokubanzi ukubhaqa ukuvuza.
3. Umgaqo osebenzayo wendlela ye-DOP yokubona ukuvuza:
I-aerosol ye-DOP ikhutshwa njengomthombo wothuli kwicala elinyukayo lesihluzo sobuchule obuphezulu esivavanywayo (i-DOP yi-dioctyl phthalate, ubunzima bemolekyuli yi-390.57, kwaye amasuntswana angqukuva emva kokutshiza).
Ifotometer ye-aerosol isetyenziselwa ukwenza isampuli kwicala lomoya osezantsi.Iisampuli zomoya eziqokelelweyo zidlula kwigumbi lokusasaza lefotometer.Ukukhanya okuhlakazekileyo okwenziwa yigesi equkethe uthuli edlula kwi-photometer iguqulwa ibe ngumbane ngempembelelo ye-photoelectric kunye ne-amplification yomgca, kwaye ibonakaliswe ngokukhawuleza nge-microammeter, i-concentration ye-aerosol ehambelanayo inokulinganiswa.Eyona nto ilinganiswayo luvavanyo lwe-DOP ngumlinganiselo wokungena we-hepa filter.
I-DOP generator sisixhobo esenza umsi.Emva kokuba i-solvent ye-DOP igalelwe kwisikhongozeli sejenereyitha, umsi we-aerosol uveliswa phantsi koxinzelelo oluthile okanye imeko yokufudumeza kwaye ithunyelwe kwicala lomoya le-high-efficiency filter (ulwelo lwe-DOP lufudunyezwa ukwenza umphunga we-DOP, kwaye umphunga ifudunyezwe kwi-Condensate ethile ibe ngamathontsi amancinci phantsi kweemeko ezithile, susa amathontsi amakhulu kakhulu kunye namancinci, ushiye kuphela malunga ne-0.3um particles, kunye ne-DOP enenkungu ingena kumbhobho womoya);
Iifotometers ze-aerosol (izixhobo zokulinganisa kunye nokubonisa ukugxilwa kwe-aerosol kufuneka zibonise ixesha elichanekileyo lokulinganisa, kwaye zingasetyenziselwa kuphela xa zidlula ukulinganisa kwaye zingaphakathi kwexesha lokuqinisekisa);
4. Inkqubo yokusebenza yovavanyo lokubona ukuvuza:
(1).Ulungiselelo lokubona ukuvuza
Lungiselela izixhobo ezifunekayo ukuze kubonwe ukuvuza kunye nesicwangciso somgangatho wombhobho wokuhanjiswa komoya wokucocwa kunye nenkqubo yokupholisa umoya kwindawo eza kuhlolwa, kwaye yazise inkampani yokucoca kunye nezixhobo zokupholisa umoya ukuba ibe kwisiza ngomhla wokuvuza. ukufumanisa ukwenza imisebenzi efana nokusebenzisa iglu kunye nokubuyisela izihluzo ze-hepa.
(2).Umsebenzi wokubona ukuvuza
①Khangela ukuba umgangatho wolwelo lwe-DOP ye-solvent kwi-aerosol generator iphezulu kunezinga eliphantsi, ukuba ayanele, kufuneka lifakwe.
②Qhagamshela ibhotile yenitrogen kwijenereyitha ye-aerosol, vula ubushushu bokutshintsha kwejeneretha ye-aerosol, kwaye ulinde de ukukhanya okubomvu kutshintshe kuluhlaza, oku kuthetha ukuba ubushushu bufikelelwe (malunga ne-390 ~ 420℃).
③Qhagamshela isiphelo sombhobho wovavanyo kwizibuko lovavanyo loxinzelelo oluphezulu lwe-aerosol photometer, kwaye ubeke esinye isiphelo kwicala lokungena komoya (icala elingasentla) lesihluzo se-hepa sivavanywa.Vula iswitshi yefotometer kwaye ulungelelanise ixabiso lovavanyo kwi "100".
④Vula umtshini we-nitrogen, lawula uxinzelelo kwi-0.05 ~ 0.15Mpa, vula ngokukhawuleza i-valve yeoli ye-aerosol generator, lawula ixabiso lokuvavanya le-photometer kwi-10 ~ 20, kwaye ungene kwi-concentration yokulinganisa okunyukayo emva kokuba ixabiso lovavanyo lizinzile.Yenza ukuskena okulandelayo kunye nemisebenzi yokuhlola.
⑤ Qhagamshela isiphelo sombhobho wovavanyo kwizibuko lovavanyo lokuxinana ezantsi kwe-aerosol photometer, kwaye usebenzise esinye isiphelo, intloko yesampulu, ukuskena icala lokuphuma komoya lesihluzi kunye nesibiyeli.Umgama phakathi kwentloko yesampuli kunye nesihluzi malunga ne-3 ukuya kwi-5 cm, ecaleni kwesakhelo sangaphakathi sesihluzo siskenwa ngasemva naphambili, kwaye isantya sokuhlola singaphantsi kwe-5cm / s.
Umda wovavanyo ubandakanya imathiriyeli yokucoca, unxibelelwano phakathi kwesixhobo sokucoca kunye nesakhelo saso, unxibelelwano phakathi kwegasket yesakhelo sokucoca kunye nesakhelo senkxaso yeqela lokucoca, unxibelelwano phakathi kwesakhelo senkxaso kunye nodonga okanye isilingi ukujonga. isihluzi esiphakathi imingxunya emincinci kunye nomnye umonakalo kwisihluzo, amatywina efreyimu, amatywina e-gasket, kunye nokuvuza kwisakhelo sokucoca.
Ukufunyaniswa kokuvuza okuvuzayo kwezihluzo ze-hepa kwiindawo ezicocekileyo ngaphezu kweklasi ye-10000 ngokuqhelekileyo kanye ngonyaka (isiqingatha sonyaka kwiindawo ezingenanto);xa kukho ukungaqhelekanga okubalulekileyo kwinani lamasuntswana othuli, iibhaktheriya ze-sedimentation, kunye nesantya somoya ekubekweni kweliso imihla ngemihla kweendawo ezicocekileyo, ukufumanisa ukuvuza kufuneka kwenziwe.
