Kana paine zvikanganiso mu hepa filter uye kuiswa kwayo, zvakaita semaburi madiki mu filter pachayo kana tumaburi tudiki tunokonzerwa nekuiswa kwakasununguka, mhedzisiro yekuchenesa kwaunoda haizowanikwe. Saka, mushure mekunge hepa filter yaiswa kana kutsiviwa, unofanirwa kuita bvunzo yekudonha kwemvura pa filter nekubatanidza kwayo.
1. Chinangwa uye huwandu hwekuona kubuda kwemvura:
Chinangwa chekuona: Nekuyedza kubuda kwehepa filter, tsvaga zvikanganiso zvehepa filter uye kuiswa kwayo, kuitira kuti utore matanho ekugadzirisa.
Nzvimbo yekuona: nzvimbo yakachena, bhenji rebasa rekuyerera kwemvura rakatsetseka uye firita yehepa pamidziyo, nezvimwewo.
2. Nzira yekuona kubuda kwemvura:
Nzira inonyanya kushandiswa ndeye DOP nzira yekuona kubuda kwemvura (ndiko kuti, kushandisa DOP solvent senzvimbo inobva guruva uye kushanda ne aerosol photometer kuona kubuda kwemvura). Nzira ye dust particle counter scanning inogona kushandiswawo kuona kubuda kwemvura (ndiko kuti, kushandisa guruva remumhepo senzvimbo inobva guruva uye kushanda ne particle counter kuona kubuda kwemvura).
Zvisinei, sezvo kuverenga kwezvikamu kuri kuverenga kwakabatana, hazvibatsiri kuskena uye kumhanya kwekuongorora kunononoka; pamusoro pezvo, kudivi rekukwira kwefirita yehepa iri kuyedzwa, huwandu hweguruva remumhepo hunowanzova hwakaderera, uye utsi hwekuwedzera hunodiwa kuti uone zviri nyore kudonha. Nzira yekuenzanisa zvikamu inoshandiswa kuona kudonha. Nzira yeDOP inogona kungogadzirisa zvikanganiso izvi, saka ikozvino nzira yeDOP inoshandiswa zvakanyanya pakuona kudonha.
3. Nheyo yekushanda kwekuona kudonha kwemvura nenzira yeDOP:
Aerosol yeDOP inoburitswa seguruva parutivi rwemhepo iri kukwira pamusoro pefirita inoshanda zvakanyanya iri kuyedzwa (DOP idioctyl phthalate, huremu hwemolekyuri i390.57, uye zvidimbu zvacho zvakatenderera mushure mekupfapfaidza).
Chiyero cheaerosol photometer chinoshandiswa pakuyedza sampuli padivi remhepo. Masampuli emhepo akaunganidzwa anopfuura nemukamuri rekupararira kwephotometer. Chiedza chakapararira chinogadzirwa negasi rine guruva chinopfuura nepaphotometer chinoshandurwa kuita magetsi nemhedzisiro yephotoelectric uye kuwedzera kwemutsara, uye chinokurumidza kuratidzwa nemicroammeter, huwandu hweaerosol hunogona kuyerwa. Chinoyerwa neDOP test ipfungwa yekupinda kwehepa filter.
Jenareta yeDOP mudziyo unogadzira utsi. Mushure mekunge DOP solvent yadururwa mumudziyo wejenareta, utsi hweaerosol hunogadzirwa pasi pekumanikidzwa kwakati kana mamiriro ekupisa uye hunotumirwa kudivi rinokwira refirita inoshanda zvakanyanya (mvura yeDOP inodziiswa kuti igadzire DOP steam, uye steam inodziiswa muCondensate chaiyo kuita madonhwe madiki pasi pemamwe mamiriro, kubvisa madonhwe akakura uye madiki, zvichisiya zvidimbu zvingangoita 0.3um, uye DOP ine mhute inopinda mumhepo inoyerera);
Ma photometer eAerosol (zvishandiso zvekuyera nekuratidza huwandu hweaerosol zvinofanira kuratidza nguva yekushanda kwe calibration, uye zvinogona kushandiswa chete kana zvikapfuura nguva yekushanda uye zviri mukati menguva yekushanda);
4. Maitiro ekushanda kwebvunzo yekuona kubuda kwemvura:
(1). Kugadzirira kuona kana mvura yabuda
Gadzirirai michina inodiwa kuti ione kana paine kudonha kwemvura uye purani yepasi pemugero wemhepo wesystem yekuchenesa nekutonhodza mhepo munzvimbo inofanira kuongororwa, uye zivisai kambani yekuchenesa nekutonhodza mhepo kuti ivepo pazuva rekuonekwa kwekudonha kwemvura kuti iite mabasa akadai sekuisa guruu nekutsiva mafirita ehepa.
(2). Kuonekwa kwekubuda kwemvura mumaziso
① Tarisa kana huwandu hwemvura hweDOP solvent mujenareta yeaerosol hwakakwira kupfuura huwandu hwakaderera, kana husina kukwana, hunofanira kuwedzerwa.
②Batanidza bhodhoro renitrogen nejenareta yeaerosol, vhura switch yekupisa yejenareta yeaerosol, womirira kusvika mwenje mutsvuku wachinja kuita girini, zvinoreva kuti tembiricha yasvika (inenge 390~420℃).
③Batanidza mugumo mumwe wepaipi yekuyedza nechiteshi chekuyedza chekumusoro cheaerosol photometer, woisa mumwe mugumo parutivi rwemhepo inopinza (kumusoro) kwefirita yehepa iri kuyedzwa. Batidza switch yephotometer wogadzirisa kukosha kwekuyedza kuita "100".
④Batidza switch yenitrogen, dzora kumanikidzwa pa0.05~0.15Mpa, vhura zvishoma nezvishoma vharuvhu yemafuta yejenareta yeaerosol, dzora kukosha kwekuyedza kwephotometer pa10~20, uye pinda muhuwandu hwakayerwa hwekumusoro mushure mekunge kukosha kwekuyedza kwagadzikana. Ita mabasa anotevera ekuongorora nekuongorora.
⑤Batanidza mugumo mumwe wepaipi yekuyedza nechiteshi chekuyedza che aerosol photometer chiri pasi, uye shandisa mumwe mugumo, musoro wekuyedza, kuti uskene divi rekubuda kwemhepo refirita nebhuraketi. Daro riri pakati pemusoro wekuyedza nefirita rinenge 3 kusvika 5 cm, pafuremu yemukati yefirita rinoskenerwa mberi neshure, uye kumhanya kwekuongorora kuri pasi pe5cm/s.
Kuyedza kunosanganisira zvinhu zvefirita, kubatana pakati pezvinhu zvefirita nefuremu yazvo, kubatana pakati pegasket yefuremu yefirita nefuremu yekutsigira yeboka refirita, kubatana pakati pefuremu yekutsigira nemadziro kana denga kuti utarise maburi madiki epakati efirita uye kumwe kukuvara mufirita, zvisimbiso zvefuremu, zvisimbiso zvegasket, uye kudonhedza kwefuremu yefirita.
Kuongororwa kwemvura inobuda mumasero ehepa munzvimbo dzakachena dziri pamusoro pekirasi 10000 kunowanzoitwa kamwe chete pagore (kaviri pagore munzvimbo dzisina tsvina); kana paine kusarongeka kukuru muhuwandu hwezvimedu zveguruva, mabhakitiriya e sedimentation, uye kumhanya kwemhepo mukutarisa nzvimbo dzakachena zuva nezuva, kuongororwa kwemvura inobuda kunofanirawo kuitwa.
