Ukulawulwa Kwebanga Lokusakazwa Kwentuthu Kokuqapha Kwemvelo Okunembile 

Ibanga lokulawula ukusakazeka kwentuthu libalulekile lapho ukuqapha kwemvelo kudinga ukunemba—hhayi ukuqagela. Sifake amasistimu angaphezu kuka-120 omthombo kanye nobuciko bamanzi emapaki ezimboni, amakhampasi ahlakaniphile, kanye ne-eco-zones kusukela ngo-2006. Kumaphrojekthi amathathu ngonyaka odlule—amabili esifundeni sase-Shenyang’s Heping kanye neyodwa endaweni yokugcinwa kwamakhemikhali—sibhekane nezinselele ezifanayo: imfucumfucu yentuthu ephuma kubhayela eseduze iphazamise ukufundwa kwezinzwa zomoya, imigqa yamanga yabangela ama-alamu angamanga. Kulapho-ke esayeka khona ukuphatha intuthu njengomsindo ongemuva—futhi saqala ukulawula ububanzi bayo bokusabalala.

Kungani Ibanga Lokuhlukanisa Liwukuguquguquka Kwangempela Ekuqaphelweni Kwemvelo

Amaqembu amaningi agxila ekuzweleni kwezinzwa noma imvamisa yokulinganisa. Kodwa idatha yethu yenkambu ikhombisa ububanzi bokusabalalisa bubusa ukuthembeka kokulinganisa. Intuthu ayiziphathi njengegesi ehlanzekile. Ukuminyana kwezinhlayiyana zayo, ukuhluka kwezinga lokushisa, kanye nokugunda komoya okuzungezile kunquma ukuthi lihamba ibanga elingakanani ngaphambi kokuhlambulula ngaphansi komkhawulo wokutholwa. Kokunye ukuhlola eduze kwendawo yokugaya izindwangu, intuthu engalawuleki isakazeke ngamamitha angu-47 ngokuvundlile ngaphambi kokuba yehlele ku-12 µg/m³ PM2.5—kodwa izinzwa ezibekwe kude ngamamitha angu-38 zibike ama-spikes ngaphezu kuka-89 µg/m³ amaminithi angu-11. Umlandu? Isivunguvungu esinqamulayo esingu-1.8 m/s esisebenzisana nezithuthukisi ezishisayo ezivela emapayipini angcolile ashisayo. Ngaphandle kokulinganisa noma ukukhawulela leyo mvilophi yokusabalalisa, alukho uhlelo lwenzwa oluletha idatha ethembekile.

Manje sehlela ibanga lokusabalalisa sisebenzisa okokufaka kwezikhathi ezintathu zangempela: ivektha yomoya yasendaweni (ekalwa ngama-anemometers e-ultrasonic ku-2 Hz), isivinini sokuphuma kwesitaki (ngamashubhu e-pitot alinganiswe ku-±1.2% esikalini esigcwele), kanye ne-delta yezinga lokushisa le-plume (i-IR thermography evunyelaniswe kokuphakelayo kwesiteshi sezulu). Lokhu akukona ukumodela okusezingqondweni—yilokho esikusebenzisayo. Ukusetha kwethu kwamanje kusebenzisa ukuxhumana kwe-Modbus RTU phakathi kweziteshi zesimo sezulu ze-Vaisala WXT530, ama-Siemens S7-1200 PLCs, kanye nemibhalo yangokwezifiso yePython ebuyekeza irediyasi yokusabalalisa njalo ngemizuzwana eyi-9. Okuphumayo kushayela ukuncishiswa ngokomzimba—hhayi izihlungi zesofthiwe.

Izindlela Ezintathu Zokulawula Eziqinisekisiwe Enkambu (kanye nokuthi Kungani Okubili Kwehluleka Ngaphansi Komthwalo)

Abanye bathi ukulawulwa kokusabalalisa akudingekile uma "ungeza izinzwa ezengeziwe." Sikuhlolile lokho. Kumshayeli wendiza wango-2023 kumasayithi ayisithupha, amagridi enzwa aminyene anciphise amaphuzu angamanga ngo-22% kuphela—kodwa akhuphule izindleko zokulungisa ngo-3.7×. Nakhu okusebenzayo ngempela:

• Izithiyo zokuchezuka kwemishini: 3-mm insimbi engagqwali baffles angle at 63° emoyeni okhona. Kufakwe amamitha angu-1.2 ukuya phezulu kwamaqoqo enzwa. Nciphisa ukungena kwentuthu okulinganisekayo ngama-84% ezimeni zomoya eziyi-18 kwezingu-21. Isebenza kahle kakhulu uma isitaki siphakama ≤ amamitha angu-8.
• Ukugeleza kwe-thermal okwenziwe kwasendaweni: Amafeni we-axial omsindo ophansi (uhlobo lwe-ECM, 42 dB(A) ku-1 m) afakwe ku-0.8 m ngezansi kwezinzwa, aqeda u-0.45 m³/s womoya we-ambient phezulu ngo-1.1 m/s. Idala i-micro-updraft ezinzile ephakamisa intuthu engenayo ngaphezu kwendiza yenzwa. Kuqinisekiswe ukusebenza kahle kufika kuma-crosswinds angu-2.3 m/s.
• Amakhethini enkungu yamanzi: Amasistimu okungewona ama-fogging—imibhobho enembile (uchungechunge lwe-Spraying Systems TJ, 0.15 mm orifice) iletha u-0.8 L/min ngemitha ngayinye yobude bekhethini. Amaconsi enkungu athwebula >68% wezinhlayiya ezingaphansi kuka-5 µm phakathi kwamasekhondi angu-0.9. Idinga ubulukhuni bamanzi <80 ppm kanye nokuhlunga okusemgqeni. Yehlulekile kabili ngenxa yokukala kwe-calcium—ngakho-ke manje sicacisa imibhobho ye-ceramic-coated.

Yini engasebenzi? Izikrini zemeshi ezingenzi lutho (ezivalwe ngamahora angu-72) nezinqamuli zamakhemikhali (i-pH engazinzile igudluze inzwa ngo-±4.3% ngesonto). Sathola ukuthi kabuhlungu—ezimbonini ezimbili zokuhlanza amanzi angcolile lapho intuthu egcwele i-ammonia isabela nge-zinc-coated mesh, yenza usawoti oshisayo owenza izinzwa zibe mfushane.

Ukuhlanganiswa Yilapho Amaphrojekthi amaningi Ekhubeka khona

Ukulawulwa kokusabalalisa akuhluleki ngenxa yokuthi i-hardware inephutha-kodwa ngoba iboshelwe kumanethiwekhi okuqapha amafa. Sibona izikhala ezintathu eziphindaphindayo zokuhlanganisa:

• Ukungahlelwanga kahle kwesikhathi: Iziteshi zesimo sezulu ezisampula njalo ngemizuzwana engama-60 kuyilapho ingqondo yokusabalalisa idinga ukubuyekezwa njalo ngemizuzwana engu-8–12. Lungisa: Engeza ungqimba lwekhompuyutha onqenqemeni (I-Raspberry Pi CM4 ene-kernel yesikhathi sangempela) kubhafa futhi wenze isampula kabusha.
• Izingxabano zesizinda samandla: Amabhasi enzwa angu-24 e-VDC ahlanganyela inkundla namasekhethi abalandeli abangu-220 VAC. Ibangela ukukhuphuka komsindo okungu-17–23 mV emigqeni ye-analogi engu-4–20 mA. Lungisa: Izimo zesignali ezihlukaniswe nge-Opto-isolated (Dataforth SCM5B35-03) ngaphambi kokufaka kwe-ADC.
• Ukukhweza amaphutha ejometri: Iziphazamiso ezibekwe ngokuhambisana nendawo yomoya esikhundleni se-perpendicular to plume centerline. Umphumela: Ukuncishiswa kwama-55% ekusebenzeni kahle. Lungisa: Sebenzisa amamitha webanga le-laser phakathi nokufakwa ukuze uqinisekise ukuqondanisa kwe-eksisi yomgoqo ukuya kusitaki phakathi kuka-±2.5°.

Manje sifaka uhlu lokuhlola lwenhlolovo yesayithi enamaphuzu ayi-15 ngaphambi kwanoma yikuphi ukusetshenziswa—okumboza amagradient ashisayo, izindawo ezikhanyayo eziseduze, ngisho nokuminyana kwezitshalo ngezikhathi ezithile zonyaka (izihlahla eziminyene zishintsha amaphrofayili omoya kufika ku-30%). Kuthatha amahora angu-3.5 endaweni. Amaklayenti akubiza ngokweqisa. Bese bebona umbiko wabo wokuzinza kwedatha wenyanga yokuqala.

Ukulawulwa Kwebanga Lokusakazwa Kwentuthu Kuyisiyalo Sokusebenza—Hhayi I-Hardware Kuphela

Lokhu akumayelana nokuthenga ibhokisi elibhalwe ukuthi “ukulawulwa kobubanzi bentuthu.” Kumayelana nokuzibophezela esilinganisweni esiqhubekayo salokho okunyakazayo-nokuthi kungani. Lonke uhlelo esilwakhayo luhlanganisa ukubonwa kwerediyasi ebukhoma ku-SCADA HMI, ebuyekezwa njalo ngemizuzwana eyi-10. Ama-opharetha awaboni nje amanani okugxilisa ingqondo kodwa nemvilophu ebonakalayo ewaqukethe. Lapho umoya ushintsha, irediyasi idweba kabusha. Lapho izinga lokushisa lesitaki lehla, ipulangwe liwela ngaphakathi. Lokho kubonakala kushintsha izinqumo.

Embonini yokukhiqiza amabhethri e-Dalian, o-opharetha basebenzise leso sibonisi ukubambezela ukukhishwa kwesithando somlilo kuze kube yilapho umoya usuka empumalanga—besika ama-alamu angamanga e-CO ngo-91% ku-Q1 2024. Kwesinye isimo, ikhampasi yenyuvesi ilungise amaphethini okufutha omthombo ngokusekelwe kumamephu okusabalalisa esikhathi sangempela, kusetshenziswa amakholomu amanzi njengezithiyo eziguqukayo eziqondile. Azikho izingxenyekazi zekhompuyutha ezintsha—izimpahla eziphinde zasetshenziswa ziqondiswa ubuhlakani bokusabalalisa.

Ukulawulwa kobubanzi bokusabalalisa intuthu kuqala ngokuvuma ukuthi indawo ayimile. Iyaphefumula, iyashintsha, iyashisa, iyaphola. Ukuqapha okunembayo kuqala lapho ukusabalalisa kugcina khona-futhi kugcine lapho ukulawula kuqala khona. Emaqenjini abalulekile mayelana nedatha engenziwa, lowo mngcele awuwona oguquguqukayo ongaziba. Ipharamitha yokuqala yokulinganisa, imodeli, nokuphatha.
