2. Isicelo
2.1 Icala langempela
Ivolumu yomoyaQUbuso bemayini buyi-3m3/s, ukumelana komoya komgudu wokungenisa umoya wasemayini ngu-0. 0045(N·s2)/m4, inani lamandla okungenisa umoyaeingu-0. 8CNY/kwh;Intengo yomzila wokungenisa umoya wemayini engu-800mm ububanzi ngu-650 CNY/pcs, intengo yepayipi lemayini yokungenisa umoya enobubanzi obungu-1000mm ngu-850 CNY/pcs, ngakho thathab= 65 CNY/m;i-coefficient yezindlekokukufakwa nokugcinwa kwe-duct kungu-0.3;ukusebenza kahle kwe-motor transmission ngu-0.95, kanti indawo yokusebenza kahle yefeni yendawo ingu-80%.Thola ububanzi bezomnotho befeni yokufaka umoya emayini.
Ngokwefomula (11), ububanzi bezomnotho bomgudu wokungenisa umoya wemayini bungabalwa kanje:
2.2 Umbhobho wokungenisa umoya we-Economical mine mine wezidingo ezahlukene zomoya
Ngokwefomula (11) kanye neminye imingcele esimweni sangempela, bala ububanzi bomgudu wokungenisa umoya wezimayini wezomnotho onevolumu yomoya ehlukene.Bheka Ithebula 4.
Ithebula 4 Ubudlelwano phakathi kwevolumu yomoya eyahlukene edingekayo ebusweni obusebenzayo kanye nobubanzi bombhobho wokungenisa umoya ukonga
| Ivolumu yomoya iyadingeka kubuso obusebenzayo/( m3· s-1) | 0.5 | 1 | 1.5 | 2 | 2.5 | 3 | 4 | 5 |
| Ububanzi bepayipi lezomnotho/mm | 0.3627 | 0.5130 | 0.6283 | 0.7255 | 0.8111 | 0.8886 | 1.0261 | 1.1472 |
Kusukela kuThebula lesi-4, kungaphethwa ngokuthi ububanzi bomgudu wokungenisa umoya ngokwezomnotho bukhulu ngokuyisisekelo kunalowo wepayipi elivamile lokungenisa umoya.Ukusetshenziswa kwe-ventilationduct ye-diameter eyongayo kunenzuzo ukwandisa umthamo womoya wobuso obusebenzayo, ukunciphisa ukusetshenziswa kwamandla, nokunciphisa izindleko zokungenisa umoya.
3. Isiphetho
3.1 Uma ipayipi lokungena komoya lemayini lisetshenziselwa ukungena komoya wendawo, ububanzi bomzila wokungenisa umoya buhlobene nezindleko zokuthenga ipayipi lokungena komoya lemayini, izindleko zikagesi wepayipi lemayini lokungena komoya, kanye nezindleko zokufakwa kanye nokugcinwa kokugcinwa kwepayipi lemayini lokungenisa umoya. .Kunobukhulu obufanele bembobo yokungena komoya emayini enezindleko eziphansi kakhulu.
3.2 Uma usebenzisa ipayipi lemayini lokungenisa umoya lasendaweni, ngokuya ngevolumu yomoya edingwa ubuso obusebenzayo, ipayipi lokungenisa umoya eliphakathi kwezomnotho lisetshenziselwa ukufeza izindleko eziphansi kakhulu zokungena komoya wendawo, futhi umphumela wokungenisa umoya muhle.
3.3 Uma ingxenye yomgwaqo ivumela, futhi izindleko zokuthengwa komgudu wokungenisa umoya wezimayini ziphansi, ububanzi bomgudu wokungenisa umoya wezomnotho kufanele bukhethwe ngangokunokwenzeka ukuze kufezwe inhloso yomthamo womoya omkhulu, ukumelana okuncane kanye nezindleko eziphansi zokungenisa umoya. ebusweni obusebenzayo.
