2. Kushandisa
2.1 Nyaya chaiyo
Huwandu hwemhepoQpakucherwa kwemugodhi i3m3/s, kupikisa kwemhepo kwemugodhi wekufefetera mugodhi i0. 0045(N·s2)/m4, mutengo wesimba rekufemesaeiri 0. 8CNY/kwh;mutengo we800mm dhayamita yemugodhi wekufefetera duct i650 CNY/pcs, mutengo wemugodhi wekufemesa mweya une dhayamita ye1000mm i850 CNY/pcs, saka torab= 65 CNY/m;mutengo wecoefficientkyekugadzika uye kugadzirisa duct iri 0.3;iyo mota yekufambisira zvakanaka ndeye 0.95, uye iko kushanda kwepoinzi kweiyo fan yemuno i80%.Tsvaga dhayamita yehupfumi yemugodhi wemhepo yekufefetera fan.
Zvinoenderana neformula (11), iyo dhayamita yehupfumi yemugodhi wekufema wemugodhi unogona kuverengerwa se:
2.2 Economical dhayamita mugodhi ventilation duct kune akasiyana mweya zvinodiwa
Zvinoenderana neformula (11) uye mamwe ma paramita mune chaiyo kesi, verenga dhayamita yehupfumi mugodhi wemhepo yekufefetera duct ine mhepo yakasiyana.Ona Tafura 4.
Tafura 4 Hukama pakati pemavhoriyamu akasiyana emhepo anodiwa pakushanda kumeso uye dhayamita yehupfumi hwekufemesa duct
| Mhepo yemhepo inodiwa pakushanda kumeso/( m3· s-1) | 0.5 | 1 | 1.5 | 2 | 2.5 | 3 | 4 | 5 |
| Economic duct dhayamita/mm | 0.3627 | 0.5130 | 0.6283 | 0.7255 | 0.8111 | 0.8886 | 1.0261 | 1.1472 |
Kubva paTafura 4, zvinogona kugumiswa kuti dhayamita yehupfumi hwemhepo yemhepo duct yakanyanya kukura kupfuura iyo yeanowanzo vhezheni duct.Iko kushandiswa kwehupfumi dhayamita ventilationduct kunobatsira kuwedzera huwandu hwemhepo hwechiso chekushanda, kuderedza kushandiswa kwesimba, uye kuderedza mari yekufema.
3. Mhedziso
3.1 Kana mugodhi wepopotera wemugodhi uchishandiswa kupinza mhepo munharaunda, dhayamita yedhairi rekufefetera rinoenderana nemutengo wekutenga kwepombi yemugodhi, mutengo wemagetsi wepombi yekufefetera mugodhi, uye kuisirwa nekuchengetedza mari yemugodhi wekufemesa mweya. .Kune yakakwana yehupfumi mugodhi wemhepo yekufemesa dhayamita ine mutengo wakaderera wakazara.
3.2 Paunenge uchishandisa mugodhi wekufemesa kwemugodhi wekufemesa kwenzvimbo, zvichienderana nehuwandu hwemhepo hunodiwa nechiso chekushanda, iyo yehupfumi dhayamita yekufemesa duct inoshandiswa kuwana iyo yakaderera mutengo wemhepo yemuno, uye mhepo yemhepo yakanaka.
3.3 Kana chikamu chemugwagwa chichibvumira, uye mari yekutenga yemugodhi wemhepo yemhepo yakaderera, dhayamita yehupfumi hwemhepo yemhepo inofanira kusarudzwa sezvinobvira kuti uwane chinangwa chemhepo yakakura, kushomeka kudiki uye mutengo wakaderera wemhepo. pachiso chekushanda.
