Ukuba kukho iziphene kwisihluzi se-hepa kunye nokufakelwa kwaso, njengemingxunya emincinci kwisihluzi ngokwaso okanye imingxunya emincinci ebangelwa kukufakelwa okukhululekileyo, isiphumo sokucoca esicetywayo asiyi kufezekiswa. Ke ngoko, emva kokuba isihluzi se-hepa sifakiwe okanye sitshintshiwe, kufuneka wenze uvavanyo lokuvuza kwisihluzi kunye noqhagamshelo lofakelo.
1. Injongo kunye nobubanzi bokuchongwa kokuvuza:
Injongo yokufunyaniswa: Ngokuvavanya ukuvuza kwesihluzo se-hepa, fumana iziphene zesihluzo se-hepa kunye nokufakelwa kwaso, ukuze kuthathwe amanyathelo okulungisa.
Uluhlu lokufunyaniswa: indawo ecocekileyo, ibhentshi yokusebenza ye-laminar flow kunye nesihluzi se-hepa kwizixhobo, njl.
2. Indlela yokufumanisa ukuvuza:
Eyona ndlela isetyenziswa kakhulu yindlela ye-DOP yokufumanisa ukuvuza (oko kukuthi, ukusebenzisa i-DOP solvent njengomthombo wothuli kunye nokusebenza nge-aerosol photometer ukufumanisa ukuvuza). Indlela yokuskena i-dust particle counter ingasetyenziselwa ukufumanisa ukuvuza (oko kukuthi, ukusebenzisa uthuli olusemoyeni njengomthombo wothuli kunye nokusebenza nge-particle counter ukufumanisa ukuvuza).
Nangona kunjalo, ekubeni ukufundwa kwekhawuntara yamasuntswana kukufundwa okuqokelelweyo, akuncedi ukuskena kwaye isantya sokuhlola sicotha; ukongeza, kwicala elinyukayo lesihluzo se-hepa phantsi kovavanyo, uxinzelelo lothuli olusemoyeni ludla ngokuba luphantsi, kwaye umsi owongezelelweyo uyafuneka ukuze kubonwe ukuvuza ngokulula. Indlela yekhawuntara yamasuntswana isetyenziselwa ukubona ukuvuza. Indlela ye-DOP inokuzilungisa ezi ngxaki, ngoko ke ngoku indlela ye-DOP isetyenziswa kakhulu ekufumaneni ukuvuza.
3. Umgaqo osebenzayo wokufumanisa ukuvuza kwendlela ye-DOP:
I-aerosol ye-DOP ikhutshwa njengomthombo wothuli kwicala elinyukayo le-filter esebenza kakuhle evavanywayo (i-DOP yi-dioctyl phthalate, ubunzima be-molecular yi-390.57, kwaye amasuntswana angqukuva emva kokutshiza).
I-aerosol photometer isetyenziselwa ukuthabatha iisampulu kwicala lomoya ophantsi. Iisampuli zomoya eziqokelelweyo zidlula kwigumbi lokusasazwa kwe-photometer. Ukukhanya okusasazekileyo okuveliswa yigesi equlethe uthuli edlula kwi-photometer kuguqulwa kube ngumbane ngesiphumo se-photoelectric kunye nokwandiswa komgca, kwaye kuboniswa ngokukhawuleza yi-microammeter, uxinzelelo oluhambelanayo lwe-aerosol lunokulinganiswa. Oko uvavanyo lwe-DOP lukulinganisa ngokwenene lizinga lokungena kwesihluzi se-hepa.
Ijenereyitha ye-DOP sisixhobo esivelisa umsi. Emva kokuba i-DOP solvent ithululelwe kwisikhongozeli sejenereyitha, umsi we-aerosol uveliswa phantsi koxinzelelo oluthile okanye imeko yokufudumeza kwaye uthunyelwa kwicala elinyukayo lesihluzo esisebenza kakuhle (ulwelo lwe-DOP luyafudunyezwa ukuze lwenze umphunga we-DOP, kwaye umphunga ufudunyezwa kwi-Condensate ethile ibe ngamaconsi amancinci phantsi kweemeko ezithile, ususe amaconsi amakhulu kakhulu namancinci kakhulu, ushiye malunga namasuntswana angama-0.3um kuphela, kwaye i-DOP enenkungu ingena kwi-air duct);
Iifotomitha ze-Aerosol (izixhobo zokulinganisa nokubonisa uxinaniso lwe-aerosol kufuneka zibonise ixesha lokusebenza lokulinganisa, kwaye zingasetyenziswa kuphela ukuba zidlulile kwixesha lokusebenza kwaye zingaphakathi kwexesha lokusebenza);
4. Inkqubo yokusebenza yovavanyo lokufumanisa ukuvuza:
(1). Ukulungiselela ukufumanisa ukuvuza
Lungisa izixhobo ezifunekayo ukuze kufunyanwe ukuvuza kunye noyilo lomgangatho wombhobho wokuhambisa umoya wenkqubo yokucoca kunye nokupholisa umoya kwindawo eza kuhlolwa, kwaye wazise inkampani yezixhobo zokucoca kunye nokupholisa umoya ukuba ibe lapho ngomhla wokufumanisa ukuvuza ukuze yenze imisebenzi efana nokusebenzisa iglu kunye nokutshintsha izihluzi ze-hepa.
(2). Umsebenzi wokufumanisa ukuvuza
①Jonga ukuba inqanaba lolwelo lwe-DOP solvent kwijenereyitha ye-aerosol liphezulu na kunenqanaba eliphantsi, ukuba alanelanga, kufuneka longezwe.
②Qhagamshela ibhotile ye-nitrogen kwijenereyitha ye-aerosol, vula iswitshi yobushushu yejenereyitha ye-aerosol, uze ulinde de isibane esibomvu sitshintshe sibe luhlaza, oko kuthetha ukuba ubushushu bufikelelwe (malunga nama-390~420℃).
③Qhagamshela isiphelo esinye sepayipi yovavanyo kwizibuko lovavanyo loxinzelelo oluphezulu lwe-aerosol photometer, uze ubeke esinye isiphelo kwicala lokungena komoya (icala elingaphezulu) le-hepa filter evavanywayo. Vula iswitshi ye-photometer uze ulungise ixabiso lovavanyo libe yi-"100".
④Vula iswitshi yenitrogen, lawula uxinzelelo kwi-0.05~0.15Mpa, vula kancinci ivalvu yeoyile yejenereyitha ye-aerosol, lawula ixabiso lovavanyo lwe-photometer kwi-10~20, uze ufake uxinzelelo olulinganisiweyo oluphezulu emva kokuba ixabiso lovavanyo lizinzile. Yenza imisebenzi elandelayo yokuskena nokuhlola.
⑤Qhagamshela isiphelo esinye sepayipi yovavanyo kwizibuko lovavanyo loxinzelelo olusezantsi lwe-aerosol photometer, kwaye usebenzise esinye isiphelo, intloko yesampulu, ukuskena icala lokukhupha umoya lefiltha kunye nebracket. Umgama phakathi kwentloko yesampulu kunye nesihluzo umalunga ne-3 ukuya kwi-5 cm, ecaleni kwesakhelo sangaphakathi sesihluzo kuskenwa ngasemva nangaphambili, kwaye isantya sokuhlola singaphantsi kwe-5 cm/s.
Ububanzi bovavanyo buquka izinto zokucoca, unxibelelwano phakathi kwezinto zokucoca kunye nesakhelo sazo, unxibelelwano phakathi kwe-gasket yesakhelo sokucoca kunye nesakhelo sokuxhasa seqela lokucoca, unxibelelwano phakathi kwesakhelo sokuxhasa kunye nodonga okanye isilingi ukujonga imingxuma emincinci ye-pinholes kunye neminye imonakalo kwi-filter, i-frame seals, i-gasket seals, kunye nokuvuza kwisakhelo sokucoca.
Ukufunyanwa rhoqo kokuvuza kwezihluzi ze-hepa kwiindawo ezicocekileyo ezingaphezulu kweklasi ye-10000 kudla ngokuba kanye ngonyaka (ixesha eliphindwe kabini ngonyaka kwiindawo ezicocekileyo); xa kukho ukungaqheleki okukhulu kwinani lamasuntswana othuli, iibhaktheriya ezibangela ukubola, kunye nesantya somoya ekubekweni esweni imihla ngemihla kweendawo ezicocekileyo, kufuneka kufunyanwe ukuvuza.
