Kana paine hurema musefa yehepa uye kuisirwa kwayo, senge maburi madiki musefa pachayo kana kutsemuka kunokonzerwa nekusagadzika kuisirwa, chinangwa chekuchenesa hachizowanikwe.Naizvozvo, mushure mekunge hepa sefa yaiswa kana kutsiviwa, inofanirwa kuita yekuvuza bvunzo pane sefa uye yekuisa kubatana.
1. Chinangwa uye chiyero chekuonekwa kwekuvuza:
Chinangwa chekuona: Nekuyedza kubuda kwesefa yehepa, tsvaga kukanganisa kwesefa yehepa nekuiswa kwayo, kuti utore matanho ekugadzirisa.
Detection renji: nzvimbo yakachena, laminar kuyerera basa bhenji uye hepa sefa pamidziyo, nezvimwe.
2. Nzira yekuona kubuda kwemvura:
Nzira inonyanya kushandiswa inzira yeDOP yekuona panobuda mvura (kureva, kushandisa DOP solvent sehupfu uye kushanda neaerosol photometer kuona panobuda).Iyo huruva particle counter scanning nzira inogonawo kushandiswa kuona panobuda (kureva, kushandisa huruva yemuchadenga senzvimbo inobvisa huruva uye kushanda nekaunda kuona panobuda mvura.
Nekudaro, sezvo iyo particle counter kuverenga kuri kuwedzera kuverenga, haikodzeri kuongorora uye kumhanya kwekuongorora kunononoka;uyezve, parutivi rwemhepo rwesefa yehepa pasi pekuyedzwa, guruva remuchadenga rinowanzove rakaderera, uye utsi hwekuwedzera hunodiwa kuti uone kubuda.Iyo particle counter method inoshandiswa kuona panobuda mvura.Iyo nzira yeDOP inogona kungogadzirisa izvo zvinoshomeka, saka ikozvino nzira yeDOP inoshandiswa zvakanyanya kuona kuvuza.
3. Nheyo yekushanda yeDOP nzira yekuona leak:
DOP aerosol inoburitswa sechitubu cheguruva kudivi remhepo repamusoro-soro sefa iri kuedzwa (DOP inonzi dioctyl phthalate, molecular weight is 390.57, uye zvimedu zvakatenderera mushure mekupfapfaidza).
Aerosol photometer inoshandiswa kuita sampling padivi pemhepo.Iwo masampuli emhepo akaunganidzwa anopfuura nemukamuri yekuparadzira yephotometer.Chiedza chakapararira chinogadzirwa neguruva-ine gasi rinopfuura nepakati pefotometer rinoshandurwa kuita magetsi neiyo photoelectric effect uye linear amplification, uye inokurumidza kuratidzwa ne microammeter, hukama hwehuwandu hweaerosol hunogona kuyerwa.Izvo zvinoyera iyo DOP bvunzo ndeyeyero yekupinda yehepa sefa.
DOP jenareta mudziyo unogadzira utsi.Mushure mekunge iyo DOP solvent yadirwa mugaba rejenareta, utsi hweaerosol hunogadzirwa pasi peimwe dzvinyiriro kana kupisa mamiriro uye inotumirwa kudivi remhepo repamusoro-soro sefa (iyo DOP mvura inopisa kuita DOP chiutsi, uye chiutsi inopisa mune chaiyo Condensate kuita madonhwe madiki pasi pemamwe mamiriro, bvisa madonhwe akakura uye madiki, achisiya chete anenge 0.3um particles, uye mhute DOP inopinda mumhepo duct);
Aerosol photometers (zviridzwa zvekuyera uye kuratidza aerosol concentrations zvinofanirwa kuratidza iyo yechokwadi nguva yecalibration, uye inogona kushandiswa chete kana ikapfuura calibration uye iri mukati menguva yechokwadi);
4. Maitiro ekushanda ekuvuza yekuongorora bvunzo:
(1).Kugadzirira kwekuona kuvuza
Gadzirira midziyo inodiwa pakuona kuvuza uye hurongwa hwepasi hweiyo mhepo yekupa duct yekucheneswa uye yemhepo-inogadzirisa mhepo munzvimbo inozoongororwa, uye zivisa kambani yekuchenesa uye yekufefetera midziyo kuti ive panzvimbo pazuva rekudonha. kuona kuita maoparesheni akadai sekuisa guruu uye kutsiva mafirita ehepa.
(2).Kubuda kwemvura
① Tarisa uone kana iyo yemvura level yeDOP solvent mujenareta yeaerosol yakakwira kupfuura yakaderera, kana isina kukwana, inofanirwa kuwedzerwa.
② Batanidza bhodhoro renitrogen kune jenareta reaerosol, vhura tembiricha yejenareta yeaerosol, uye mirira kusvika mwenje dzvuku wachinja kuita girinhi, zvinoreva kuti tembiricha yasvikwa (inenge 390 ~ 420 ℃).
③Batanidza imwe magumo epombi yebvunzo kune yakakwira chiteshi chekuyedza cheaerosol photometer, uye isa imwe magumo parutivi rwemhepo inopinza (kurutivi rwekumusoro) kwehepa sefa iri kuedzwa.Batidza chinja chephotometer uye gadzirisa kukosha kwebvunzo ku "100".
④Batidza nitrogen switch, dzora kudzvanywa pa 0.05 ~ 0.15Mpa, zvishoma nezvishoma vhura valve yemafuta yejenareta yeaerosol, dzora kukosha kwekuyedza kwephotometer pa10 ~ 20, uye pinda mumhepo yakayerwa yekumisikidza mushure mekunge kukosha kwebvunzo kugadzikana.Ita zvinotevera scanning uye kuongorora mabasa.
⑤ Batanidza imwe mugumo wepombi yekuyedza kune yakadzika yekudzika bvunzo chiteshi cheiyo aerosol photometer, uye shandisa imwe magumo, sampling musoro, kutarisa mhepo yekubuda kwesefa uye bracket.Chinhambwe chiri pakati pemusoro wesampling nesefa chinenge 3 kusvika 5 cm, pamwe nemukati mesefa inotariswa kumashure nekudzoka, uye kumhanya kwekutarisa kuri pazasi 5cm / s.
Chiyero chekuyedza chinosanganisira iyo sefa zvinhu, kubatana pakati pesefa zvinhu uye furemu yayo, kubatana pakati pegasket refirita furemu uye chimiro chekutsigira cheboka remafirita, kubatana pakati pechitsigiro furemu nemadziro kana sirin'i kutarisa. iyo sefa yepakati madiki pinholes uye kumwe kukuvadza musefa, furemu zvisimbiso, gasket zvisimbiso, uye inobuda mufirita furemu.
Routine yekuona kuvuza kwemasefa ehepa munzvimbo dzakachena pamusoro pekirasi 10000 kazhinji kamwe pagore (semi-pagore munzvimbo dzisina utachiona);kana paine kusakosha kwakakosha muhuwandu hweguruva, mabhakitiriya ekunyungudika, uye kukurumidza kwemhepo mukutarisisa kwezuva nezuva kwenzvimbo dzakachena, kuburitswa kwemvura kunofanirwawo kuitwa.
