Tunnel yekuvaka ventilation nzira dzakakamurwa kuita echisikigo kufefetedza uye mechanic ventilation zvinoenderana nekunobva simba. Mechanical ventilation inoshandisa simba remhepo rinogadzirwa neventilation fan yekufemesa.
Nzira dzekutanga dzekugadzira tunnel yekuvaka mechanic ventilation inonyanya kusanganisira kuvhuvhuta kwemhepo, kubuda kwemhepo, kupihwa kwemhepo uye exhaust yakasanganiswa, yakasanganiswa uye nzira.
1. Air blowing type
Iyo mhepo inovhuvhuta yemhepo inofefetera duct iri kunze kwemugero, uye mhepo yekubuda iri pedyo nechiso chemugero. Pasi pechiito chefani, mweya mutsva unotumirwa kuchiso chemugero uchibva kunze kwemugero kuburikidza nemapaipi kuti usvibise zvinosvibisa, uye mweya wakasviba unodonhedzwa kunze, uye marongerwo anoratidzwa muMufananidzo 1.
2. Air exhaust type
Mhepo inopera yakakamurwa kuva yakanaka kumanikidzwa exhaust mhando uye yakashata kumanikidza exhaust mhando. Mhepo inopinza ye duct iri pedyo nechiso chemugero, uye mhepo yekubuda iri kunze kwemugero. Pasi pechiito chefani, mweya mutsva unopfuura nepamugero uchienda kuchiso chemugero, uye mweya wevitiated unoburitswa zvakananga kubva pamukoto kuenda kunze. Kurongeka kwayo kunoratidzwa muMufananidzo 2 uye Mufananidzo 3.
3. Mhepo inovhuvhuta uye mhepo inopera yakasanganiswa mhando
Mhepo inovhuvhuta uye mhepo inoputika yakasanganiswa mhando isanganiswa yemhepo inovhuvhuta uye inopedza mweya. Iine mafomu maviri, imwe ndeyekumanikidza kwakanaka kunopedza yakasanganiswa mhando, uye imwe yacho isimba rakaipa rinopisa rakasanganiswa mhando, sezvakaratidzwa muFigure 4 neFigure 5.
Pasi pechiito chefani, mweya mutsva unopinda mugero uchibva kunze kwemugero, unoyerera uchienda kunopinda nemhepo yekuvhuvhuta uye wopinda mumhepo inofefetera duct, uye unosvika kuchiso chemugero kuburikidza nemhepo inofefetera yemhepo, uye mweya wemhepo unoyerera uchibva kunzira kuenda kunopinda mugero rekuburitsa kubva mugero remhepo, pinda mugero rekunze, pinda nemugero rekunze. exhaust duct.
4. Combination type
Mhepo inovhuvhuta mhando uye exhaust mhando inoshandiswa panguva imwe chete kugadzira musanganiswa wemhando. Saizvozvo, kune marudzi maviri ekushandisa musanganiswa, yakanaka kumanikidza kupera simba musanganiswa wekushandisa uye yakaipa yekumanikidza kupera simba musanganiswa kushandiswa.
Chikamu chemweya mutsva chinotumirwa kuchiso chemugero kuburikidza nemhepo inofefetera yemhepo, chikamu chemweya mutsva unopinda mumugero kubva kunze kwemugero, chikamu chemhepo yakasvibiswa inoyerera ichibva kuchiso chemugero ichienda pamusuwo wepombi yekuburitsa, uye chimwe chikamu chemhepo nyowani kubva mugero inonyungudutsa zvinosvibisa munzira. Mushure mekunge mhepo yakaomeswa yayerera ichienda kunopinda nepombi yepombi, mweya miviri yakasvibiswa inoyerera ichipinda mupombi yekuburitsa uye inoburitswa kunze kwemugero. Kurongeka kunoratidzwa muMufananidzo 6 uye Mufananidzo 7.
5. Rudzi rwenzira
Iyo nzira yemugwagwa yakakamurwa kuva jet roadway type uye main fan roadway type.
Jet tunnel mhando iri pasi pechiito chejet fan, mweya mutsva unopinda uchibva kune imwe mugero kuburikidza nemugero wemhepo, mweya wakaomarara unoburitswa kubva kune imwe mugero, uye mweya mutsva unosvika pachiso chemugero kuburikidza nemhepo inofefetera yemhepo. Chimiro chinoratidzwa mumufananidzo 8.
Iyo huru fan tunnel mhando iri pasi pekuita kweiyo huru fan, mweya mutsva unopinda uchibva kune imwe mugero, mweya weviated unoburitswa kubva kune imwe mugero, uye mweya mutsva unogoverwa kuchiso chemugero nemugero wekufemesa. Chimiro chinoratidzwa mumufananidzo 9.
