Ulawulo loLuhlu lokusasazwa komsi ukulungiselela ukuJonga okuNgqongileyo okuNgqongileyo 

Uluhlu lolawulo lokusasazwa komsi lubalulekile xa ukujonga imekobume kufuna ukuchaneka—hayi ukuqikelela. Sifake phezu kwe-120 imithombo yamanzi kunye neenkqubo zobugcisa bamanzi kwiipaki zoshishino, iikhampasi ezihlakaniphile, kunye ne-eco-zones ukususela ngo-2006. Kwiiprojekthi ezintathu zonyaka odlulileyo-ezimbini kwiSithili sase-Shenyang's Heping kunye nenye kwindawo ye-chemical logistics hub-sijongene nemingeni efanayo: iiplamu zomsi ezivela kwi-boiler stacks ezikufutshane ziphazamise ukufundwa kwenzwa yomsindo, i-alarm esekelwe emoyeni yobuxoki. Kulapho sayeka khona ukuphatha umsi njengengxolo yangasemva-kwaye saqalisa ukulawula uluhlu lwayo losasazo.

Kutheni Uluhlu lweDiffusion iluGuquko lokwenyani kuHlolo lokusiNgqongileyo

Uninzi lwamaqela ajolise kubuntununtunu boluvo okanye ukuphindaphindwa kokulinganisa. Kodwa idatha yethu yentsimi ibonisa ukuba uluhlu losasazo lulawula ukuthembeka komlinganiselo. Umsi awuziphathi njengegesi ecocekileyo. Ukuxinana kwayo kwamasuntswana, umahluko wobushushu, kunye nokuchetywa komoya okungqongileyo kumisela ukuba iwuhamba kangakanani na phambi kokuhlanjululwa ngezantsi kwemigangatho yobhaqo. Kolunye uvavanyo kufutshane nelitye lokusila, umsi ongalawulekiyo usasazeke ngeemitha ezingama-47 ngokuthe tye phambi kokuhla ukuya kwi-12 µg/m³ PM2.5—kodwa abenzi boluvo babekwe kumgama oziimitha ezingama-38 baxela izikhonkwane ngaphezulu kwe-89 µg/m³ kangangemizuzu eyi-11. Umoni? I-1.8 m/s crosswind edibana nohlaziyo olushushu oluvela kwimibhobho yamanzi amdaka ashushu. Ngaphandle kokulinganisa okanye ukunyanzela loo mvulophu yosasazo, akukho luhlu lwesivamvo lunikezela ngedatha ethembekileyo.

Ngoku senza imaphu yoluhlu losasazo sisebenzisa amagalelo amathathu exesha lokwenyani: ivektha yomoya yasekhaya (elinganiswa nge-ultrasonic anemometers ku-2 Hz), isantya sokuphuma esipakishweni (ngeetyhubhu zepitot zilinganiswe ukuya ku-±1.2% isikali esigcweleyo), kunye nedelta yobushushu be-plume (IR thermography engqanyaniswe kwisondlo sesikhululo semozulu). Oku ayisiyiyo imodeli yethiyori-yinto esiyithumelayo. Ukuseta kwethu kwangoku kusebenzisa unxibelelwano lwe-Modbus RTU phakathi kwezikhululo zemozulu zeVaisala WXT530, ii-Siemens S7-1200 PLCs, kunye nezikripthi zePython zesiko ezihlaziya irediyo ye-diffusion rhoqo ngemizuzwana eyi-9. Isiphumo siqhuba ukuthomalalisa ngokwasemzimbeni-hayi izihluzi zesoftware.

Iindlela eziNtathu zoLawulo eziQinisekisiweyo (kwaye kutheni ezimbini zisilela phantsi komthwalo)

Abanye bathi ulawulo lokusasaza aluyomfuneko ukuba "ukongeza nje ezinye izinzwa." Sayivavanya loo nto. Kwi-pilot ye-2023 kwiindawo ezithandathu, iigridi ze-sensor ezixineneyo zinciphisa ii-positives zobuxoki kuphela nge-22%-kodwa ziphakamisa iindleko zokugcinwa kwe-3.7 ×. Nantsi eyona nto isebenzayo:

• Imiqobo yokuphambuka koomatshini: 3-mm iibhaffle zentsimbi estainless ezijikelwe kwi-63 ° ukuya kwimimoya ekhoyo. Kufakwe i-1.2 yeemitha phezulu komjelo wamaqela oluvo. Ukunciphisa ukungena komsi okunokulinganiswa ngama-84% kwiimeko zomoya ezili-18 kwezingama-21. Isebenza kakuhle xa istaki sobude ≤ 8 yeemitha.
• Ukuhamba kwe-thermal yendawo: Iifeni ze-axial ezinengxolo ephantsi (uhlobo lweECM, 42 dB(A) kwi-1 m) inyuswe nge-0.8 m ngaphantsi kwabenzi boluvo, ikhupha i-0.45 m³/s yomoya ojikeleze phezulu kwi-1.1 m/s. Yenza i-micro-updraft ezinzileyo ephakamisa umsi ongenayo ngaphezu kwendiza yenzwa. Iqinisekisiwe ukusebenza ukuya kuthi ga kwi-2.3 m/s crosswinds.
• Iikhethini zenkungu yamanzi: Iinkqubo ze-fogging-i-nozzles ezichanekileyo (I-Spraying Systems TJ series, i-0.15 mm orifice) ihambisa i-0.8 L / min ngemitha yobude bekhethini. Amathontsi enkungu abamba i-68% yamasuntswana angaphantsi kwe-5 µm kwimizuzwana eyi-0.9. Ifuna ubulukhuni bamanzi <80 ppm kunye nokuhluzwa okungaphakathi. Ayiphumelelanga kabini ngenxa yokulinganisa i-calcium-ke ngoku sikhankanya imilomo egqunywe ngeceramic.

Yintoni engasebenzi? Izikrini ze-mesh ze-Passive (zivaliwe kwiiyure ze-72) kunye ne-chemical neutralizers (i-pH engazinzanga iguqule i-sensor drift nge-± 4.3% ngeveki). Safumanisa ukuba kunzima—kwimizi-mveliso emibini yokucocwa kwamanzi amdaka apho umsi ozele yiammonia udityaniswe nezinc-coated mesh, usenza iityuwa ezikwaziyo ukuvala iisensi.
