Uma kunamaphutha esihlungi se-hepa nokufakwa kwawo, njengezimbobo ezincane kusihlungi uqobo noma imifantu emincane ebangelwa ukufakwa okuxekethile, umphumela wokuhlanza okuhlosiwe ngeke uzuzwe. Ngakho-ke, ngemuva kokuthi isihlungi se-hepa sifakiwe noma sifakwe esikhundleni, kufanele sihlolwe ukuvuza kuhlungi nokufakwa kokufakwa.
1. Inhloso kanye nobubanzi bokutholwa okuvuzayo:
Injongo yokutholwa: Ngokuhlola ukuvuza kwesihlungi se-hepa, thola iziphambeko zesihlungi se-hepa nokufakwa kwawo, ukuze kuthathwe izinyathelo zokulungisa.
Uhla lokutholwa: indawo ehlanzekile, i-laminar flow umsebenzi webhentshini kanye ne-hepa Hlunga ngemishini, njll.
2. Indlela yokutholwa yokutholwa:
Indlela esetshenziswa kakhulu yindlela ye-DOP yokutholwa okuvuzayo (okungukuthi, ukusebenzisa i-DOP solvent njengomthombo wothuli futhi usebenza nge-aerosol photometer ukuthola ukuvuza). Indlela yokuthwebula i-Counter Counter Counter Counter nayo ingasetshenziselwa ukuthola ukuvuza (okungukuthi, kusetshenziswa uthuli lomkhathi njengomthombo wothuli futhi lusebenza ngekhawunta yezinhlayiya.
Kodwa-ke, ngoba ukufundwa kwezinhlayiyana okulwa yizinhlayiyana kufundwa okuqongelelayo, akukufanele ukuskena futhi ijubane lokuhlola lihamba kancane; Ngaphezu kwalokho, ohlangothini olukhuphukile lwesihlungi se-hepa ngaphansi kokuhlolwa, ukugxila kothuli komkhathi kuvame ukwehlisa, futhi intuthu eyengeziwe iyadingeka ukuthola kalula ukuvuza. Indlela ye-Partic Counter Indlela isetshenziselwa ukuthola ukuvuza. Indlela ye-DOP ingavele ikwenze lokhu ukushiyeka, ngakho-ke manje indlela ye-DOP isetshenziselwa kakhulu ukutholwa okuvuzayo.
3. Umgomo osebenzayo wokutholwa kokuvuza kwe-DOP:
I-DOP Aerosol ikhishwe njengomthombo wothuli ohlangothini olusezingeni eliphezulu lokuvezwa okuphezulu kokuhlolwa (i-dop yi-dioctyl perthalate, isisindo molecular is 390.57, kanye nezinhlayiya ziyindilinga ngemuva kokufafaza).
I-aerosol photometer isetshenziselwa ukusampula ohlangothini oluphansi. Amasampula endiza aqoqiwe adlula ehlathini le-Photometer. Isibani esihlakazekile esikhiqizwa yigesi equkethe igesi equkethe uthuli nge-photometer siguqulwa sibe ngogesi ngomphumela we-photoelectric kanye nokukhuliswa okuqondile, futhi kuboniswa ngokushesha yi-micrommeter, ukugcwala okuhlobene ne-aerosol kungalinganiswa. Lokho okuhlolo kwe-DOP empeleni kungokulinganisa izinga lokungena kwesihlungi se-hepa.
I-DOP Generator iyithuluzi elikhiqiza intuthu. Ngemuva kokuthi i-solvent ye-dop ithululelwa esitsheni sojeneli, intuthu ye-aerosol ikhiqizwa ngaphansi kwengcindezi ethile noma isimo sokushisa futhi ithunyelwa ohlangothini oluphezulu lwesihlungi esisebenza kahle (i-dop liquid ifudunyezwa ukwakha i-dop Steam, kanye nomusi ukufuthelelwa ku-condensate ethile kumaconsi amancane ngaphansi kwezimo ezithile, susa amaconsi amakhulu kakhulu futhi amancane kakhulu, ashiye izinhlayiya ezi-0.3um kuphela, futhi i-fopgy dop ingena i-duct yomoya);
Ama-Photosol Photosol (amathuluzi okulinganisa nokubonisa ukugxila kwe-aerosol kufanele abonise isikhathi sokuvunyelwa kokulinganisa, futhi angasetshenziswa kuphela uma edlula isikhathi sokuba semthethweni);
4. Inqubo Yokusebenza Yokuhlola Ukutholwa:
(1). Ukulungiselela Ukutholwa Kwe-Leak
Lungiselela imishini edingekayo ekutholweni okuvuzayo kanye necebo eliphansi lokukhishwa komoya kohlelo lokuhlanzwa nohlelo lokuhlanza endaweni okufanele luhlolwe, futhi wazise inkampani yokuhlanzwa kanye ne-air-activity company ukuze ibe sendaweni yosuku lokuvuza Ukutholwa ukwenza imisebenzi efana nokusebenzisa i-glue futhi kubuyise izihlungi ze-hepa.
(2). Ukusebenza kokutholwa kokutholwa
① Check ukuthi izinga loketshezi le-dop solvent ku-aerosol generator liphakeme kunezinga eliphansi, uma linganele, kufanele lingezwe.
② Cindezela ibhodlela le-nitrogen ku-aerosol generator, vula ukushintshwa kwamazinga okushisa kwe-aerosol generator, bese ulinda kuze kube yilapho ukukhanya okubomvu kuguquka kube luhlaza, okusho ukuthi izinga lokushisa lifinyelelwe (cishe ama-390 ~ 420 ℃).
③ Cindezela okukodwa kokuhlolwa kwe-hose test to the upstream Photometer Test Port ye-Aerosol Photometer, bese ubeka omunye umkhawulo ohlangothini lwe-air inlet (uhlangothi olusezingeni eliphezulu) lokuhlunga kwe-HEPA Vula i-Photometer Shintsha bese ulungisa inani lokuhlola ku- "100".
④Turn on the nitrogen switch, lawula ingcindezi ku-0.05 ~ 0.15mpa, vula kancane i-valve kawoyela ye-aerosol generator, lawula kancane inani lokuhlola le-photosometer ku-10 ~ 20, bese ufaka i-Upstream elilinganise ukugxila ngemuva kokuqina kwenani lokuhlola. Yenza imisebenzi yokuskena nokuhlola okulandelayo.
⑤ Cindezela okukodwa kokuhlolwa kwe-hose test to the Dowstream Throgection Test Port ye-Aerosol Photometer, bese usebenzisa elinye ukuphela, ikhanda lesampula, ukuskena uhlangothi lokuphuma komoya kwesihlungi kanye nebakaki. Ibanga phakathi kwekhanda lesampula kanye nesihlungi cishe esingu-3 kuye kwangama-5 cm, kanye nohlaka lwangaphakathi lwesihlungi kuskena emuva naphambili, futhi ijubane lokuhlola lingaphansi kwe-5cm / sper c.
Ububanzi bokuhlola bufaka impahla yokuhlunga, ukuxhumana phakathi kwezihlungi kanye nohlaka lwayo, ukuxhumana phakathi kwe-gasket yohlaka lokuhlunga kanye nohlaka lokusekelwa kweqembu lokuhlunga, uhlaka noma uphahla ukuze uhlole Izihlungi ezi-medium eziphakathi kanye nomonakalo wokuhlunga, izimbotshana zozimele, izimbotshana ze-gasket, nokuvuza ngohlaka lokuhlunga.
Ukutholwa okuvuthiwe okujwayelekile kwezihlungi ze-hepa ezindaweni ezihlanzekile ngaphezulu kweklasi 10000 ngokuvamile kanye ngonyaka (unyaka nonyaka ezindaweni ezinyumba); Lapho kunezifo ezibalulekile enanini lezinhlayiya zothuli, amagciwane edimentation, kanye ne-air velocity ekuqapheleni nsuku zonke kwezindawo ezihlanzekile, ukutholwa okuvuzayo kufanele futhi kwenziwe.
