Uma kukhona amaphutha kusihlungi se-hepa kanye nokufakwa kwaso, njengemigodi emincane kusihlungi ngokwaso noma imifantu emincane ebangelwa ukufakwa okuxekethile, umphumela wokuhlanza ohlosiwe ngeke ufezwe. Ngakho-ke, ngemva kokufakwa noma ukushintshwa kwesihlungi se-hepa, kumele wenze ukuhlolwa kokuvuza ekuxhumekeni kwesihlungi nokufakwa.
1. Inhloso kanye nobubanzi bokutholwa kokuvuza:
Inhloso yokuthola: Ngokuhlola ukuvuza kwesihlungi se-hepa, thola amaphutha esihlungi se-hepa kanye nokufakwa kwaso, ukuze kuthathwe izinyathelo zokulungisa.
Uhla lokuthola: indawo ehlanzekile, ibhentshi lokusebenza lokugeleza kwe-laminar kanye nesihlungi se-hepa emishinini, njll.
2. Indlela yokuthola ukuvuza:
Indlela esetshenziswa kakhulu yindlela ye-DOP yokuthola ukuvuza (okungukuthi, ukusebenzisa i-DOP solvent njengomthombo wothuli kanye nokusebenza nge-aerosol photometer ukuthola ukuvuza). Indlela yokuskena i-dust particle counter ingasetshenziswa futhi ukuthola ukuvuza (okungukuthi, ukusebenzisa uthuli olusemoyeni njengomthombo wothuli kanye nokusebenza nge-particle counter ukuthola ukuvuza).
Kodwa-ke, njengoba ukufundwa kwekhawunta yezinhlayiya kuyisifundo esihlanganisiwe, akuhambisani nokuskena futhi isivinini sokuhlola sihamba kancane; ngaphezu kwalokho, ohlangothini olukhuphukayo lwesihlungi se-hepa ngaphansi kokuhlolwa, ukugcwala kothuli lomoya kuvame ukuba phansi, futhi intuthu eyengeziwe iyadingeka ukuze kutholakale kalula ukuvuza. Indlela yekhawunta yezinhlayiya isetshenziselwa ukuthola ukuvuza. Indlela ye-DOP ingalungisa lokhu kuntuleka, ngakho-ke manje indlela ye-DOP isetshenziswa kabanzi ekutholeni ukuvuza.
3. Umgomo wokusebenza wokuthola ukuvuza kwendlela ye-DOP:
I-aerosol ye-DOP ikhishwa njengomthombo wothuli ohlangothini olukhuphukayo lwesihlungi esisebenza kahle kakhulu esivivinywayo (i-DOP yi-dioctyl phthalate, isisindo sama-molecule singama-390.57, kanti izinhlayiya ziyindilinga ngemva kokufutha).
I-aerosol photometer isetshenziselwa ukusampula ohlangothini lomoya ophansi. Amasampula omoya aqoqiwe adlula ekamelweni lokusabalalisa le-photometer. Ukukhanya okuhlakazekile okukhiqizwa yigesi equkethe uthuli edlula ku-photometer kuguqulwa kube ugesi ngomphumela we-photoelectric kanye nokukhulisa okuqondile, futhi kuboniswa ngokushesha yi-microammeter, ukuhlushwa okuhlobene kwe-aerosol kungalinganiswa. Lokho ukuhlolwa kwe-DOP okukulinganisayo ngempela izinga lokungena kwesihlungi se-hepa.
Ijenereyitha ye-DOP iyithuluzi elikhiqiza intuthu. Ngemva kokuba i-solvent ye-DOP ithululelwe esitsheni sejenereyitha, intuthu ye-aerosol ikhiqizwa ngaphansi kwengcindezi ethile noma isimo sokushisa bese ithunyelwa ohlangothini oluphezulu lwesihlungi esisebenza kahle kakhulu (uketshezi lwe-DOP luyashiswa ukuze lwakhe umusi we-DOP, bese umusi ushiswa ku-Condensate ethile ube amaconsi amancane ngaphansi kwezimo ezithile, kususwe amaconsi amakhulu kakhulu namancane kakhulu, kushiye cishe izinhlayiya ezingu-0.3um kuphela, bese i-DOP enenkungu ingena emgudwini womoya);
Ama-photometer e-Aerosol (izinsimbi zokulinganisa nokubonisa ukugcwala kwe-aerosol kufanele zibonise isikhathi sokusebenza kokulinganisa, futhi zingasetshenziswa kuphela uma zidlula ukulinganisa futhi zingaphakathi kwesikhathi sokusebenza);
4. Inqubo yokusebenza yokuhlola ukuvuza:
(1). Ukulungiselela ukuthola ukuvuza
Lungisa imishini edingekayo ukuze kutholakale ukuvuza kanye nohlelo lwephansi lomsele wokuhambisa umoya wohlelo lokuhlanza nokupholisa umoya endaweni ezohlolwa, bese wazisa inkampani yemishini yokuhlanza nokupholisa umoya ukuthi ibe khona ngosuku lokutholwa kokuvuza ukuze yenze imisebenzi efana nokusebenzisa iglue nokufaka izihlungi ze-hepa esikhundleni.
(2). Umsebenzi wokuthola ukuvuza
①Hlola ukuthi izinga loketshezi lwe-DOP solvent ku-aerosol generator liphakeme yini kunezinga eliphansi, uma linganele, kufanele lifakwe.
②Xhuma ibhodlela le-nitrogen kujeneretha ye-aerosol, vula iswishi yokushisa yejeneretha ye-aerosol, bese ulinda kuze kube yilapho ukukhanya okubomvu kushintshela kuluhlaza, okusho ukuthi izinga lokushisa selifinyelelwe (cishe ku-390~420℃).
③Xhuma umkhawulo owodwa wepayipi lokuhlola echwebeni lokuhlola lokuhlushwa elingaphezulu kwe-aerosol photometer, bese ubeka omunye umkhawulo ohlangothini lokungena komoya (uhlangothi oluphezulu) lwesihlungi se-hepa esivivinywayo. Vula iswishi ye-photometer bese ulungisa inani lokuhlola libe ngu-"100".
④Vula iswishi ye-nitrogen, lawula ingcindezi ku-0.05~0.15Mpa, vula kancane ivalvu kawoyela yejeneretha ye-aerosol, lawula inani lokuhlola le-photometer ku-10~20, bese ufaka ukuhlushwa okulinganisiwe okuphezulu ngemva kokuba inani lokuhlola lizinzile. Yenza imisebenzi elandelayo yokuskena nokuhlola.
⑤Xhuma umkhawulo owodwa wepayipi lokuhlola echwebeni lokuhlola lokuhlushwa elingezansi le-aerosol photometer, bese usebenzisa umkhawulo omunye, ikhanda lokuhlola, ukuskena uhlangothi lokukhipha umoya lwesihlungi kanye ne-bracket. Ibanga phakathi kwekhanda lokuhlola nesihlungi lingaba ngu-3 kuya ku-5 cm, ohlakeni lwangaphakathi lwesihlungi liyaskenwa emuva naphambili, kanti ijubane lokuhlola lingaphansi kuka-5 cm/s.
Ububanzi bokuhlola buhlanganisa izinto zokuhlunga, ukuxhumana phakathi kwezinto zokuhlunga nohlaka lwazo, ukuxhumana phakathi kwe-gasket yohlaka lokuhlunga kanye nohlaka lokusekela lweqembu lokuhlunga, ukuxhumana phakathi kohlaka lokusekela kanye nodonga noma uphahla ukuze kuhlolwe izimbobo ezincane eziphakathi zokuhlunga kanye nokunye ukulimala kusihlungi, izivalo zohlaka, izivalo zohlaka, kanye nokuvuza kohlaka lokuhlunga.
Ukutholwa kokuvuza okuvamile kwezihlungi ze-hepa ezindaweni ezihlanzekile ezingaphezu kwesigaba 10000 ngokuvamile kwenzeka kanye ngonyaka (okwenziwa kabili ngonyaka ezindaweni ezihlanzekile); lapho kukhona ukungalingani okukhulu enanini lezinhlayiya zothuli, amabhaktheriya e-sedimentation, kanye nesivinini somoya ekuqapheni nsuku zonke izindawo ezihlanzekile, ukutholwa kokuvuza kufanele kwenziwe futhi.
