I-GQ-AEC2232bX-P
Iyini igesi ye-VOC?
I-VOC yisifinyezo samakhemikhali e-volatile organic. Ngomqondo ojwayelekile, i-VOC ibhekisela ekubunjweni kwamakhemikhali e-volatile organic; Kodwa-ke, maqondana nokuvikelwa kwemvelo, ibhekisela ekilasini lamakhemikhali e-volatile organic asebenzayo futhi ayingozi. Izingxenye eziyinhloko ze-VOC zifaka phakathi ama-hydrocarbon, ama-hydrocarbon e-halogenated, ama-hydrocarbon e-oxygen, nama-hydrocarbon e-nitrogen, kufaka phakathi amakhemikhali ochungechunge lwe-benzene, ama-chloride e-organic, uchungechunge lwe-fluorine, ama-ketone e-organic, ama-amine, ama-alcohols, ama-ether, ama-esters, ama-acid, nama-hydrocarbon e-petroleum. Futhi uhlobo lwamakhemikhali abeka usongo olukhulu empilweni yabantu.
Yiziphi izingozi zegesi ye-VOC?
Yiziphi izindlela zokuthola amagesi e-VOC?
Iyini isimiso se-PID detector?
Ukutholwa kwe-Photoionization (PID) kusebenzisa imisebe ye-ultraviolet ekhiqizwa yi-ionization yegesi engasebenzi yinsimu kagesi evame kakhulu ukuze kufakwe ama-molecule egesi ngaphansi kokuhlolwa. Ngokulinganisa amandla amanje akhiqizwa yigesi efakwe ama-ion, kutholakala ukuhlushwa kwegesi ngaphansi kokuhlolwa. Ngemva kokutholwa, ama-ion aphinde ahlangane abe yigesi yokuqala kanye nomhwamuko, okwenza i-PID ibe yinto yokuhlola engonakalisi.
Inzwa ye-PID ethuthukiswe ngokwayo
Insimu kagesi evuselelayo ehlakaniphile
Impilo ende
Ukusebenzisa isinxephezelo esihlakaniphile ukuvusa insimu kagesi, kwandisa kakhulu impilo yezinzwa (impilo engaphezu kweminyaka emi-3)
Ubuchwepheshe bamuva bokuvala
Ukuthembeka okuphezulu
Ifasitela lokuvala lisebenzisa izinto ze-magnesium fluoride ezihlanganiswe nenqubo entsha yokuvala, okugwema ngempumelelo ukuvuza kwegesi okungavamile nokuqinisekisa isikhathi sokuphila kwenzwa.
Indandatho yokuqoqa igesi emafasiteleni
Ukuzwela okuphezulu nokunemba okuhle
Kukhona indandatho yokuqoqa igesi efasiteleni lesibani se-UV, okwenza i-ionization yegesi ibe yinkimbinkimbi kakhulu futhi ukutholwa kube bucayi futhi kube nembaba.
Izinto ze-Teflon
Ukumelana nokugqwala nokuqina okuqinile
Izingxenye ezikhanyiswa izibani ze-ultraviolet zonke zenziwe ngezinto ze-Teflon, ezinekhono eliqinile lokulwa nokugqwala futhi zinganciphisa ijubane le-oxidation yi-ultraviolet ne-ozone.
Isakhiwo segumbi elisha
Ukuzihlanza nokuzilungisa akudingi
Uhlobo olusha lomklamo wesakhiwo segumbi olunomklamo wesiteshi sokugeleza esengeziwe ngaphakathi kwenzwa, engavunguza futhi ihlanze inzwa ngqo, inciphise ngempumelelo ukungcola epayipini lesibani futhi ifinyelele inzwa engenakulungiswa
I-pump suction detector eyenzelwe ngqo i-PID sensor entsha ivumela i-sensor ukuthi ifinyelele ukusebenza kahle okuphezulu, inikeze imiphumela engcono yokuthola kanye nolwazi olungcono lomsebenzisi.
Izinga lokulwa nokugqwala lifinyelela ku-WF2 futhi lingakwazi ukuzivumelanisa nezimo ezahlukahlukene zomswakama ophezulu kanye nezimo zokufutha ngosawoti omningi (Ukufutha izinto ezilwa nokugqwala ngopende we-fluorocarbon egobolondweni)
Inzuzo 1: Azikho izixwayiso ezingamanga ezindaweni ezinokushisa okuphezulu kanye nomswakama
Lokhu kuhlola kulingisa ukuhlolwa okuqhathanisayo phakathi kwezitholi ze-PID zendabuko kanye nezitholi ze-PID zezinzwa ezimbili endaweni enomswakama ophezulu ongu-55 ° C. Kungabonakala ukuthi izitholi ze-PID zendabuko zinokushintshashintsha okukhulu kokuhlushwa kule ndawo futhi zithambekele ekuhlaselweni ngamanga. Futhi isitholi se-PID sezinzwa ezimbili esinelungelo lobunikazi se-Anxin asiguquguquki kakhulu futhi sizinzile kakhulu.
Inzuzo 2: Ukuphila isikhathi eside kanye nokugcinwa okungenakho
Inzwa entsha ye-PID
ukuqapha okuhlangene
Ukuhlunga okunezigaba eziningi
Thola inzwa ye-PID ephila iminyaka engaphezu kwemi-3 futhi engenakho ukulungiswa phakathi nokuphila kwayo
Impumelelo ebalulekile efana nokuphila kwezinzwa ze-catalytic
Inzuzo 3: Umklamo we-Modular, ukufakwa okulula kanye nokugcinwa
Imodyuli yesenzwa ye-PID, ingavulwa ngokushesha futhi ihlukaniswe ukuze ilungiswe
Iphampu ye-Modular, esheshayo ukuxhuma nokufaka esikhundleni
Imodyuli ngayinye ifinyelele ukwakheka kwemodyuli, futhi zonke izingxenye ezisengozini nezisebenzisekayo zishintshwe ngokushesha nangokulula.
Ukuhlolwa kokuqhathanisa, ukuqhathanisa okuphezulu nokuphansi
Ukuqhathaniswa nemikhiqizo yezinzwa ze-PID ezingenisiwe ezingalashwanga
Ukuhlolwa okuqhathanisayo nohlobo oluthile lwemishini yokuthola emakethe

Mayelana nemibuzo ngama-detector e-PID?
Impendulo: Umkhiqizo oqalwe kulokhu uthatha indawo yenzwa ye-PID yakamuva ethuthukisiwe yenkampani yethu, eshintshe isakhiwo segumbi lomoya (umklamo wesiteshi sokugeleza) kanye nemodi yokunikezwa kwamandla. Umklamo wesiteshi sokugeleza okhethekile unganciphisa ukungcola kokukhanya futhi ufeze ukusula amashubhu esibani angenawo amandla ngokuhlunga okunezinga eziningi. Ngenxa yemodi yokunikezwa kwamandla okuphakathi eyakhelwe ngaphakathi yenzwa, ukusebenza okuphakathi kuyashelela futhi kuhlakaniphe kakhulu, futhi ukutholwa okuhlangene nezinzwa ezimbili kufeza impilo engaphezu kweminyaka emi-3.
Impendulo: Imisebenzi eyinhloko yebhokisi lemvula ukuvimbela amanzi emvula kanye nomusi wezimboni ukuthi ungawuthinti ngqo umshini wokuthola. 2. Vimbela umthelela wezindawo zokushisa okuphezulu kanye nomswakama kuma-PID detectors. 3. Vimba uthuli oluthile emoyeni bese ubambezela isikhathi sokuphila sesihlungi. Ngokusekelwe ezizathwini ezingenhla, sifake ibhokisi elingangenisi imvula njengejwayelekile. Vele, ukwengeza ibhokisi elingangenisi imvula ngeke kube nomthelela omkhulu esikhathini sokuphendula kwegesi.
Impendulo: Kufanele kuqashelwe ukuthi iminyaka emi-3 yokungabi nokugcinwa kusho ukuthi inzwa ayidingi ukunakekelwa, futhi isihlungi sisadinga ukunakekelwa. Siphakamisa ukuthi isikhathi sokugcinwa kwesihlungi ngokuvamile siyizinyanga eziyi-6-12 (sifinyezwe sibe yizinyanga ezi-3 ezindaweni ezinobungozi zemvelo)
Impendulo: Ngaphandle kokusebenzisa izinzwa ezimbili zokuthola amalunga, inzwa yethu entsha ingafinyelela impilo yeminyaka emi-2, ngenxa yenzwa yethu entsha ye-PID (ubuchwepheshe obunelungelo lobunikazi, isimiso esijwayelekile singabonakala esigabeni sesibili). Imodi yokusebenza yokutholwa kwamalunga e-semiconductor+PID ingafinyelela impilo yeminyaka emi-3 ngaphandle kwezinkinga.
Impendulo: a. I-Isobutene inamandla aphansi kakhulu e-ionization, ene-Io engu-9.24V. Ingafakwa i-ionized ngezibani ze-UV ku-9.8eV, 10.6eV, noma ku-11.7eV. b. I-Isobutene inobuthi obuphansi futhi iyigesi ekushiseni kwegumbi. Njengegesi yokulinganisa, ayilimazi impilo yabantu. c. Intengo ephansi, kulula ukuyithola
Impendulo: Ngeke yonakale, kodwa ukugxila okuphezulu kwegesi ye-VOC kungabangela igesi ye-VOC ukuthi inamathele efasiteleni nase-electrode isikhathi esifushane, okuholela ekungasabelini kwenzwa noma ekunciphiseni ukuzwela. Kuyadingeka ukuhlanza ngokushesha isibani se-UV kanye ne-electrode nge-methanol. Uma kukhona isikhathi eside sokuba khona kwegesi ye-VOC edlula i-1000PPM endaweni, ukusebenzisa izinzwa ze-PID akubizi kakhulu futhi kufanele kusetshenziswe izinzwa ze-infrared ezingasabalali.
Impendulo: Isixazululo esijwayelekile i-PID engasifinyelela yi-isobutene engu-0.1ppm, kanti inzwa ye-PID engcono kakhulu ingafinyelela i-isobutene engu-10ppb.
Ukuqina kokukhanya kwe-ultraviolet. Uma ukukhanya kwe-ultraviolet kunamandla kakhulu, kuzoba nama-molecule egesi amaningi angaguqulwa abe yi-ion, futhi ukucaca kuzoba ngcono ngokwemvelo.
Indawo ekhanyayo yesibani se-ultraviolet kanye nendawo engaphezulu kwe-electrode eqoqayo. Indawo ekhanyayo enkulu kanye nendawo ye-electrode eqoqayo enkulu ngokwemvelo kuphumela ekukhanyeni okuphezulu.
Ugesi we-offset we-preamplifier. Uma ugesi we-offset we-preamplifier umncane, ugesi obonakalayo uba buthakathaka. Uma ugesi we-bias we-amplifier yokusebenza mkhulu, isignali yamandla awusizo abuthakathaka izocwiliswa ngokuphelele kugesi we-offset, futhi ukulungiswa okuhle akukwazi ukutholakala ngokwemvelo.
Ukuhlanzeka kwebhodi lesifunda. Amasekethe e-analog ahlanganiswe namabhodi esifunda, futhi uma kukhona ukuvuza okukhulu ebhodini lesifunda, amaza abuthakathaka awakwazi ukuhlukaniswa.
Ubukhulu bokumelana phakathi kwamandla kagesi kanye ne-voltage. Inzwa ye-PID ingumthombo wamandla kagesi, futhi amandla kagesi angakhuliswa kuphela futhi alinganiswe njenge-voltage nge-resistor. Uma ukumelana kuncane kakhulu, izinguquko ezincane ze-voltage azikwazi ukufezwa ngokwemvelo.
Isixazululo se-ADC ye-analog-to-digital. Uma isinqumo se-ADC siphezulu, isignali kagesi engaxazululwa iba ncane, futhi isixazululo se-PID siba ngcono.
