Iyo infrared oiri mita chishandiso chinoshandiswa zvakanyanya kuyera mafuta ari mumvura. Inoshandisa musimboti we infrared spectroscopy kuongorora quantitatively mafuta ari mumvura. Iine zvakanakira kukurumidza, kwakaringana uye kuri nyore, uye inoshandiswa zvakanyanya mukutarisisa kunaka kwemvura, kuchengetedza kwezvakatipoteredza uye mamwe minda.
Oiri musanganiswa wezvinhu zvakasiyana-siyana. Zvinoenderana neiyo polarity yezvikamu zvayo, inogona kukamurwa kuita mapoka maviri: petroleum uye mhuka nemafuta emiriwo. Polar mhuka nemafuta emiriwo anogona kushambadzwa nezvinhu zvakaita se magnesium silicate kana silica gel.
Petroleum zvinhu zvinonyanya kuumbwa nemakemikari ehydrocarbon akadai sealkanes, cycloalkanes, anonhuwirira hydrocarbons, uye alkenes. Iyo hydrocarbon yemukati inoita 96% kusvika 99% yehuwandu. Kuwedzera kumahydrocarbon, zvinhu zvepetroleum zvinewo okisijeni, nitrogen, uye sarufa zvishoma. Hydrocarbon derivatives yezvimwe zvinhu.
Mafuta emhuka nemiriwo anosanganisira mafuta emhuka nemafuta emuriwo. Mafuta emhuka mafuta anotorwa kubva kumhuka. Iwo anogona kazhinji kukamurwa kuita epasi emhuka oiri nemafuta emhuka dzemugungwa. Mafuta emiriwo mafuta anowanikwa kubva mumichero, mbeu, uye utachiona hwezvirimwa. Izvo zvakakosha zvemafuta emiriwo ane mutsara wakakwira mafuta acids uye triglycerides.
Kunobva kusvibiswa kwemafuta
1. Mafuta anosvibisa zvakatipoteredza zvikuru anobva mutsvina yemumaindasitiri netsvina yemumba.
2. Maindasitiri akakosha eindasitiri anoburitsa petroleum zvinosvibisa anonyanya maindasitiri akadai semafuta asina kukora, kugadzirwa, kutakura uye kushandiswa kwemafuta akacheneswa akasiyana-siyana.
3. Mafuta ezvipfuyo nemuriwo anonyanya kubva mutsvina yemumba uye masuweji eindasitiri yekubika. Pamusoro pezvo, maindasitiri akaita sesipo, pendi, ingi, rabha, kusukuta, machira, zvekuzora nemishonga zvinorasa mamwe mafuta emhuka nemiriwo.
Njodzi dzezvakatipoteredza dzemafuta ① Kukuvadza kumvura zvivakwa; ② Kukuvadza kune ivhu kwezvakatipoteredza; ③ Kukuvadza kubata hove; ④ Kukuvadza kune zvirimwa zvemumvura; ⑤ Kukuvadza mhuka dzemumvura; ⑥ Kukuvadza kumuviri wemunhu
1. Nheyo ye infrared mafuta mita
Infrared oiri detector imhando yechiridzwa chinoshandiswa zvakanyanya mumasisitimu ekutarisa nharaunda, petrochemical indasitiri, hydrology uye kuchengetedza mvura, makambani emvura, zvidyarwa zvekuchenesa tsvina, zvidyarwa zvemagetsi zvinopisa, makambani esimbi, yunivhesiti yekutsvagisa nekudzidzisa, yekurima nharaunda yezvekurima, kutarisa nharaunda yechitima. , kugadzirwa kwemotokari, Marine Instruments yekutarisa kwezvakatipoteredza, traffic traffic monitoring, kwezvakatipoteredza sainzi tsvakiridzo uye mamwe makamuri ekuyedza uye marabhoritari.
Kunyanya, iyo infrared oiri mita inovhenekera sampu yemvura pane infrared light source. Mamorekuru emafuta ari mumucherechedzo wemvura anotora chikamu chechiedza che infrared. Oiri yemukati inogona kuverengerwa nekuyera chiedza chakabatwa. Nekuti zvinhu zvakasiyana zvinotora mwenje kune akasiyana wavelengths uye kusimba, marudzi akasiyana emafuta anogona kuyerwa nekusarudza chaiwo mafirita uye ma detectors.
Kushanda kwayo musimboti kunobva pane HJ637-2018 chiyero. Kutanga, tetrachlorethylene inoshandiswa kubvisa zvinhu zvemafuta mumvura, uye iyo yose inotorwa inoyerwa. Ipapo iyo yakatorwa inoshambadzirwa ne magnesium silicate. Mushure mokunge zvinhu zvepolar zvakadai semafuta emhuka nemiriwo zvabviswa, mafuta acho anoyerwa. mutsa. Iyo yakazara inobvisa uye petroleum yemukati inotarwa nenhamba yemafungu e2930cm-1 (kutambanudza vibration yeCH bond muCH2 boka), 2960cm-1 (kutambanudza vibration yeCH bond muCH3 boka) uye 3030cm-1 (aromatic hydrocarbons). Iko kunyura paA2930, A2960 uye A3030 pakutambanudza kudzungudza kweCH bond) bhendi yakaverengerwa. Izvo zviri mukati memhuka nemafuta emiriwo zvinoverengerwa semusiyano pakati pese kubviswa uye petroleum yemukati. Pakati pavo, mapoka matatu, 2930cm-1 (CH3), 2960cm-1 (CH2), uye 3030cm-1 (aromatic hydrocarbons), ndiwo makuru emafuta epetroleum mineral. "Chero musanganiswa" mukuumbwa kwayo unogona "kuunganidzwa" kubva kumapoka matatu aya. Nokudaro, zvinogona kuonekwa kuti kugadziriswa kwemafuta epetroleum kunongoda huwandu hwemapoka matatu ari pamusoro apa.
Iko kushandiswa kwemazuva ese kweiyo infrared oil detectors inosanganisira asi haina kuganhurirwa kune anotevera mamiriro: Inogona kuyera zviri mukati petroleum, senge mineral oiri, akasiyana einjini mafuta, mechanical oiri, mafuta ekuzora, ekugadzira mafuta uye akasiyana ekuwedzera ane kana kuwedzera; panguva imwe chete Izvo zvinehukama zvema hydrocarbons akadai se alkanes, cycloalkanes uye anonhuwirira hydrocarbons anogona kuyerwa zvakare kuti anzwisise zviri mukati oiri mumvura. Pamusoro pezvo, infrared oiri inocherekedza inogona zvakare kushandiswa kuyera mahydrocarbon mune organic zvinhu, senge organic zvinhu zvinogadzirwa nekutsemuka kwepetroleum hydrocarbons, mafuta akasiyana siyana, uye zvigadzirwa zvepakati mukugadzira organic matter.
2. Kuchengetedza kwekushandisa infrared mafuta detector
1. Kugadzirira kwemuenzaniso: Usati washandisa infrared oil detector, sampu yemvura inoda kugadziridzwa. Sampuli dzemvura dzinowanzoda kusefa, kutorwa uye mamwe matanho ekubvisa tsvina uye zvinhu zvinokanganisa. Panguva imwecheteyo, zvinodikanwa kuve nechokwadi chekumiririrwa kwemasampuli emvura uye kudzivirira kuyerwa kukanganisa kunokonzerwa nekusaenzana sampling.
2. Reagents uye zvakajairwa zvinhu: Kuti ushandise infrared oiri detector, unofanirwa kugadzirira anowirirana reagents uye zvakajairwa zvinhu, senge organic solvents, pure mafuta samples, nezvimwe. Izvo zvinodikanwa kuterera kuchena uye nguva yechokwadi yemareagents. , woatsiva uye woagadzirisa nguva nenguva.
3. Instrument calibration: Usati washandisa iyo infrared oiri mita, calibration inodiwa kuti uve nechokwadi chekuyera kurongeka. Zvishandiso zvakajairwa zvinogona kushandiswa kuenzanisa, uye iyo calibration coefficient yechiridzwa inogona kuverengerwa zvichibva pane absorption spectrum uye inozivikanwa zvirimo zveyakajairwa zvinhu.
4. Tsanangudzo yekushanda: Paunenge uchishandisa infrared oiri mita, unofanirwa kutevedzera maitiro ekushanda kuti udzivise kushanda kwakashata kunokanganisa mhedzisiro yekuyera. Semuenzaniso, sampuli inoda kuchengetwa yakagadzikana panguva yekuyerwa kwekuita kuti udzivise kudedera uye kukanganisa; zvinodikanwa kuve nechokwadi chehutsanana uye kuisirwa kwakaringana kana uchitsiva mafirita uye ma detectors; uye zvinodikanwa kusarudza algorithms akakodzera uye nzira dzekuverenga panguva yekugadzirisa data.
5. Kuchengetedza uye kugadzirisa: Ita nguva dzose kugadzirisa pane infrared mafuta detector kuchengetedza midziyo mumamiriro akanaka. Semuenzaniso, gara uchichenesa mafirita uye ma detectors, tarisa kana magetsi masosi uye maseketi ari kushanda nemazvo, uye gara uchigadzirisa uye kugadzirisa zviridzwa.
6. Kubata mamiriro asina kujairika: Kana ukasangana nemamiriro asina kujairika panguva yekushandiswa, senge abnormal mibairo yekuyera, kutadza kwemidziyo, nezvimwewo, unofanirwa kurega kuishandisa nekukurumidza uye kugadzirisa dambudziko. Iwe unogona kutarisa kune iyo midziyo bhuku kana kubata nyanzvi tekinoroji kuti igadziriswe.
7. Kurekodha uye kuchengetedza: Panguva yekushandiswa, zviyero zvekuyera uye mamiriro ekushanda kwemidziyo zvinoda kurekodhwa uye kuchengetwa kuti zviongorore uye kubvunzurudza. Panguva imwecheteyo, kutarisisa kunoda kubhadharwa kuchengetedza zvakavanzika zvemunhu uye kuchengetedzwa kweruzivo.
8. Kudzidzira uye dzidzo: Vashandi vanoshandisa infrared oiri detectors vanofanira kudzidziswa uye dzidzo kuti vanzwisise nheyo, nzira dzekushanda, dziviriro, nezvimwe zvemidziyo. Kudzidziswa kunogona kuvandudza hunyanzvi hwevashandisi uye kuve nechokwadi chekushandisa kwakaringana kwemidziyo uye huchokwadi hwedata.
9. Mamiriro ezvakatipoteredza: Infrared oiri detectors ine zvimwe zvinodiwa zvemamiriro ekunze, sekushisa, humidity, electromagnetic interference, etc. Panguva yekushandiswa, unofanirwa kuve nechokwadi kuti mamiriro ezvakatipoteredza anosangana nezvinodiwa. Kana pane abnormalities, unofanira kugadzirisa uye kugadzirisa.
10. Kuchengetedzwa kwerabhoritari: Chengetedza kuchengetedzwa kwerabhoritari panguva yekushandiswa, sekudzivisa mareagents kubva paganda, kuchengetedza mhepo, nezvimwewo. Panguva imwecheteyo, kutarisisa kunofanirwa kubhadharwa pakurasa tsvina uye kuchenesa marabhoritari kuti uve nechokwadi chehutsanana uye kuchengetedzeka. nzvimbo yerabhoritari.
Parizvino, iyo itsva infrared oiri mita LH-S600 yakagadziriswa neLianhua ine 10-inch high-definition touch screen uye yakavakirwa-mukati piritsi komputa. Inogona kushandiswa zvakananga pakombiyuta yepafurafura pasina kudiwa kwekombiyuta yekunze uye ine zvishoma zvekukundikana. Inogona kuratidza zvine hungwaru magirafu, inotsigira sampuli yekutumidza zita, sefa uye kuona mhinduro dzebvunzo, uye kuwedzera HDMI interface kune yakakura skrini kutsigira kurodha data.
