2. Isicelo
2.1 Eyona meko
Umthamo womoyaQubuso bokomba bomgodi yi-3m3/s, ukuxhathisa komoya kumbhobho wokungena umoya womgodi yi-0. 0045(N·s2)/m4, ixabiso lamandla okungena komoyaeyi-0. 8CNY/kwh;Ixabiso le-800mm yedayamitha ye-ventilating duct mgodi yi-650 CNY/pcs, ixabiso lombhobho wokungenisa umoya wemigodi onobubanzi obuyi-1000mm yi-850 CNY/pcs, ngoko thathab= 65 CNY/m;i-coefficient yeendlekokyofakelo kunye nokugcinwa kombhobho yi-0.3;ukusebenza kakuhle kokuhanjiswa kwemoto yi-0.95, kwaye indawo yokusebenza yomqhubi wendawo yi-80%.Fumana i-diameter yezoqoqosho ye-fan ye-ventilation yasemgodini.
Ngokwefomula (11), i-diameter yezoqoqosho yombhobho wokungenisa umoya wemigodi ingabalwa ngolu hlobo:
2.2 Umbhobho wokungenisa umoya wedayamitha yoqoqosho yeemfuno ezahlukeneyo zomoya
Ngokutsho kwefomula (11) kunye nezinye iiparameters kwimeko yokwenyani, bala ububanzi bombhobho wezoqoqosho we-ventilation duct kunye nomthamo womoya owahlukileyo.Jonga kwiTheyibhile 4.
Itheyibhile 4 Ubudlelwane phakathi kwemithamo yomoya eyahlukeneyo efunekayo kubuso obusebenzayo kunye nobubanzi bombhobho wokungenisa umoya wezoqoqosho
| Umthamo womoya ofunekayo kubuso obusebenzayo/( m3· s-1) | 0.5 | 1 | 1.5 | 2 | 2.5 | 3 | 4 | 5 |
| Umbhobho wezoqoqosho ubukhulu / mm | 0.3627 | 0.5130 | 0.6283 | 0.7255 | 0.8111 | 0.8886 | 1.0261 | 1.1472 |
Ukususela kwiThebhile 4, kunokugqitywa ukuba ububanzi bombhobho wokungenisa umoya wezoqoqosho bukhulu kakhulu kunombhobho oqhelekileyo wokungenisa umoya.Ukusetyenziswa kwe-ventilationduct ye-diameter yezoqoqosho kunenzuzo ukunyusa umthamo womoya wobuso obusebenzayo, ukunciphisa ukusetyenziswa kwamandla, kunye nokunciphisa iindleko zokungenisa umoya.
3. Isiphelo
3.1 Xa umjelo wokungena komoya osemgodini usetyenziselwa indawo yokuphuma komoya yasekuhlaleni, ububanzi bombhobho wokungenisa komoya bunxulumene neendleko zokuthenga umjelo wokungenisa umoya womgodi, iindleko zombane wombhobho wokungenisa umoya womgodi, kunye neendleko zofakelo kunye nokugcinwa kwexabiso lombhobho wokungenisa umoya womgodi. .Kukho owona mbhobho webhobho wokungenisa umoya ofanelekileyo woqoqosho ngeyona ndleko iphantsi iyonke.
3.2 Xa usebenzisa umbhobho we-ventilation womgodi wokungena komoya wendawo, ngokuhambelana nomthamo womoya ofunwa ngubuso obusebenzayo, i-duct ye-economic diameter ye-ventilation isetyenziselwa ukufezekisa iindleko eziphantsi kakhulu zokungena komoya wendawo, kwaye umphumo wokungena umoya ulungile.
3.3 Ukuba icandelo lendlela yendlela livumela, kwaye iindleko zokuthengwa kombhobho wokungenisa umoya wemigodi ziphantsi, ububanzi bombhobho wokungenisa umoya wezoqoqosho kufuneka bukhethwe kangangoko kunokwenzeka ukufezekisa injongo yomthamo omkhulu womoya, ukuchasana okuncinci kunye neendleko eziphantsi zokungenisa umoya. ebusweni obusebenzayo.
