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 oku kusilela, ke ngoku indlela ye-DOP isetyenziswa kakhulu ekubhaqweni kokuvuza.
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-effective filter (ulwelo lwe-DOP lufudunyezwa ukwenza umphunga we-DOP, kwaye umphunga ufudunyezwa kwi-Condensate ethile ibe ngamathontsi amancinci phantsi kweemeko ezithile, susa amathontsi amakhulu kakhulu kunye namancinci kakhulu, kwaye ishiya kuphela i-DOP yomoya ingena ngaphakathi;
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 ekubhaqeni ukuvuza kunye nesicwangciso somgangatho we-air supply duct yokucoca kunye ne-air-conditioning system kwindawo eya kuhlolwa, kwaye yazise inkampani yokucoca kunye ne-air-conditioning yezixhobo ukuba ibe kwisiza ngomhla wokufumanisa ukuvuza ukwenza imisebenzi efana nokusebenzisa iglue kunye nokutshintsha 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 kwe-gasket yesakhelo sokucoca kunye nesakhelo senkxaso yeqela lokucoca, unxibelelwano phakathi kwesakhelo senkxaso kunye nodonga okanye isilingi ukukhangela isihluzi esiphakathi kweepinhole ezincinci kunye nomnye umonakalo kwisihluzi, izitywina zesakhelo, ukutywinwa kwe-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.
