Umkhiqizo isingeniso ka Into Single Burning
SBI ukuhlolwa, okusho monomer omlilo test, indlela ejwayelekile entsha eyanyatheliswa bese zilandelwa ngu-European Union ukuhlola izici omlilo of izinto. Le ndinganiso usebenzisa isimiso esifanayo njengoba ekhoneni umlilo test and Isigaxa Calorimeter. Izinga yokuhlola phakathi kwalezi ezimbili. I SBI test izinyathelo ushintsho umoya-mpilo lokuhlushwa ngesikhathi sesivivinyo, kanye flue igesi ukugeleza kanye CO2 lokuhlushwa iphayiphi. Ngu kubalwa ukushisa Ukukhululwa izinga ngesikhathi esithile, lo FIGRA Inkomba ukushisa Ukukhululwa izinga, esiphezulu ukushisa ukukhululwa rate quotient isikhathi inqubo yokuhlola, is, kulinganiswa esisetshenziselwa ahlukanisa retardancy ilangabi ukwakha izinto.
Lonke imishini yokuhlola kuhlanganisa amandla omlilo laboratory, indlu yokulawula, inqola, intuthu qeda ipayipi, iqoqo ledatha kudivayisi ukuhlaziywa, igesi ukunikezela ukulawula idivayisi. Ukuhlolwa kwenziwa egumbini amandla omlilo nge ekuphakameni 2.4M futhi indawo 3M X 3m. Kwakukhona igesi lokuqoqa hood umusi qeda ipayipi exhunywe ne izibonelo zalokho ipayipi phezulu ekamelweni, futhi kwakukhona isikhala nomoya ukungena ophumayo ngokwemvelo ngaphansi inqola. Ngesikhathi sesivivinyo, ukushisa ezikhishwe omlilo isampula kanye imikhiqizo amandla omlilo akhishwe ipayipi qeda. A izibonelo zalokho endaweni oluphelele luyatholakala emsini qeda ipayipi ngokufaka izinzwa kanye izibonelo zalokho amashubhu. Negesi lokushisa, lokuhlushwa compounds omlilo ezikhishwe, umoya-mpilo okuhlushwa, attenuation ukukhanya gas flue, inani ukugeleza rate umoya amandla omlilo imikhiqizo alinganiswe e ipayipi izibonelo zalokho.
Izici yomkhiqizo nokusebenzisa Into Single Burning
1. Monomer imishini amandla omlilo test kuhlanganisa inqola, Uhlaka fixed, igesi ngalendoda, ngalendoda, J-uhlobo qeda ipayipi, umlandeli centrifugal, umoya control ijubane kudivayisi, oluphelele nesilinganiso kwesigaba, igesi ukuhlaziywa iKhabhinethi, uhlelo yokufuna idatha, njll
2. Sibona ikani ifakwe zezinhlobo ezimbili Okusizayo perpendicular isampula. Ezansi le engela mpo, kukhona isihlabathi ibhokisi sikaphalafini. Ebusweni ukuthungela imodi esenziwayo, nelangabi uhlelo ukuthola ifakwe njengoba idivayisi zokucisha Ukuvikelwa.
3. Fixed uzimele. I inqola bephushelwa kuwo ukuhlola ukusekela igesi lokuqoqa kwenzakalani. Kuvele sikaphalafini asizayo athe njó uzimele. Ngesikhathi esifanayo, uhlelo ukuthola ilangabi ifakwe ukwenza njenge idivayisi Ukuvikelwa wokukucima umlilo.
4. engagqwali igesi ngalendoda itholakala phezulu ifreyimu fixed ukuqoqa igesi eyenziwe amandla omlilo.
5. Insimbi steel J-uhlobo intuthu qeda ipayipi, ukushisa-nangokuvikela ipayipi isiyingi nge ububanzi elingaphakathi (315 +5) mm, ngci nge 50 mm obukhulu ukushisa ukumelana amaminerali uvolo;
6. yentuthu ohlelweni qeda kufanele ukwazi ngokuqhubekayo ngibheme futhi intuthu qeda ngejubane 0.50 m3 / s-0.65 m3 / s, futhi kumele kuhanjiswe ngokwezidingo zomThetho imvamisa ukuguqulwa.
7. Insimbi steel fan centrifugal, okungase ukumelana degrees 300 lokushisa, lihlangabezana okusezingeni eliphezulu lokushisa imfuneko isinyathelo Samandla.
8. IMisa ukugeleza isilawuli nge uhla 0 g / s-2.5 g / s, ukunemba kokufunda hhayi ngaphansi kuka 1.5%;
9. Ngokwenza izinguquko propane ukugeleza rate ngokusebenzisa mass ukugeleza isilawuli, supply igesi sikaphalafini kufanele ilawulwe ngokuzenzakalelayo. Le gesi mass ukugeleza rate kuyinto 647 mg / s 2000 mg / s. Uhlelo lokulawula igesi kungaqinisekisa ukuthi ushintsho ijubane igesi ukunikezela kumele singeqi 5 mg / s kanti ukushisa okukhipha kufanele kube 30.7 + 2 kW.
10. I flue igesi amasampuli uhlelo siqukethe umlotha lemifanekiso, compressor epholisayo, omiswe ikholomu, izibonelo zalokho futha futha peristaltic ukuqinisekisa ukuqoqwa ephumelelayo igesi amasampula flue nokwesula ahlanzekile.
11. diaphragm futha, ukugeleza rate: 400l / h, izinga lokushisa eliphezulu futhi ukugqwala ukumelana, esetshenziselwa izibonelo zalokho igesi;
12. Ikhanda lemifanekiso intuthu nothuli isihlungi yakhiwa PTFE esiqinile ngezinto ezingashi 0.5um isihlungi ngaphakathi impahla.
13. samandla epholisayo, ukupholisa umthamo 320KJ / h, amazolo iphuzu ukuzinza 0.1 degree, amazolo iphuzu static ushintsho 0.1K, Ukuvikelwa ezingeni IP20;
14. Ngenisa Rotor flowmeter, ukulinganisa lebanga 0-5L / imiz, ulungise ukugeleza izinga analyzer.
15. Paramagnetic-mpilo analyzer, ukulinganisa lebanga 0-25%, ukulinganisa-mpilo lokuhlushwa igesi, lokuhlushwa lebanga 0-25%, T90 <imizuzwana 12;
16. Non-dispersive infrared CO2 analyzer: CO2: 0-10%;
17. iphayiphi nge ubude 2155 mm ifakwe ingcindezi uphenyo, thermocouples ezintathu, igesi izibonelo zalokho Uphenyo nomhlophe uhlelo ukukhanya.
18. Uphenyo bi Ohlangothi ixhunyiwe nge amazwe ingcindezi inzwa ngobubanzi wokulinganisa okungenani (0-100) Pa kanye ukunemba (+2 Pa). Isikhathi Ukusabela ka-90% okukhiphayo ingcindezi inzwa 1 s okungenani.
19. igesi izibonelo zalokho Uphenyo ixhunyiwe ngedivayisi igesi umqondo kanye amazwe igesi analyzer O2 kanye CO2.
20. Ukukhanya attenuation uhlelo uhlobo esikhipha, kanye ngokuhlanganyela nezimo efakwe ohlangothini ipayipi ipayipi qeda.
21. Isibani kuyinto isibani esikhipha futhi lisetshenziswe kweyesi (2900 + 100) K umbala lokushisa. I kwamandla kuyinto isitebele DC samanje, futhi uhla ukuguquguquka zamanje luphakathi (+ 0.5%) (kuhlanganise lokushisa, yesikhathi esifushane neyezinto ukuzinza eside).
22. A lens uhlelo ngokugxila ukukhanya ku ugodo parallel ububanzi okungenani 20 mm. I beso elikhanyayo we phototube kufanele sise ayiphoyinti lens phambi kwalo, futhi ubukhulu bayo (d) kumele kunqunywe ubude ebalulekile (f) se-lens ukuze d / f lingaphansi kuka 0.04.
23. umtshina futhi probe Silicon photodiode abe ukuzinza komugqa 0.1% kanye 10-bit nesilinganiso ibanga. I Spectral ukusatshalaliswa ukubhekana eqondana Silicon photodiode ne CIE (okukhanyisa ijika). Izinga umsebenzi V (gamma) ingafinyelela okungenani (+ 5%) ukunemba.
24. 90% impendulo nesikhathi optical attenuation uhlelo akufanele idlule bo-3.
25. Air busuka ohlangothini tube ukugcina optical idivayisi ngokwanele ihlanzekile ukuhlangabezana nemfuneko yokukhanya attenuation drift. Umoya onomfutho zingasetshenziswa ukufeza lokhu.
