Simba rinodiwa nefeni kufambisa mhepo mumishini yekufemesa mweya rinopihwa nefani. Kune marudzi maviri emafeni anowanzo shandiswa: centrifugal uye axial: ① Centrifugal mafeni ane yakakwirira feni musoro uye yakaderera ruzha. Pakati pavo, fan-inopetera ine mashizha emhepo-yakafanana nemhepo yakaderera-ruzha uye yepamusoro-soro fan. Dongguan ventilation equipment ② Axial kuyerera feni, pasi pemamiriro eiyo dhayamita imwechete yekutenderera uye kumhanya kwekutenderera, mhepo yekumanikidza yakadzikira pane yemhando yecentrifugal, uye ruzha rwakakwira kupfuura rwemhando yecentrifugal. Inonyanya kushandiswa kune ventilation systems ine diki system resistance; mabhenefiti makuru madiki saizi uye nyore kuisa. , inogona kuiswa zvakananga pamadziro kana mupombi.

Iwo mafeni anoshandiswa mumhepo inofefetera akakamurwa kuita guruva-risingapindi mafeni, mafeni anoputika, uye anorwisa-corrosion mafeni zvinoenderana nesvikiro rekufambisa.

Mhepo sefa Kuti uve nechokwadi chehutano hwevanhu uye kusangana nezvinodiwa zvehutsanana hwemhepo kune mamwe maitiro ekugadzira maindasitiri (senge indasitiri yechikafu, nezvimwewo), mweya unotumirwa mukamuri unofanirwa kucheneswa kune madhigirii akasiyana. Mafirita emhepo anowanzo shandiswa mumasisitimu ekupa mweya kubvisa guruva mumhepo. Zvinoenderana neakasiyana efiltration efficiencies, mafirita emhepo akakamurwa kuita zvikamu zvitatu: coarse, medium and high performance. Kazhinji waya mesh, girazi faibha, furo, synthetic fiber uye pepa refirita zvinoshandiswa sefirita zvinhu.

Muunganidzi weguruva nemidziyo yekuchenesa gasi inokuvadza Kana huwandu hwetsvina mumhepo yabuda huchipfuura mwero wekuburitsa guruva, muunganidzi weguruva kana gasi rinokuvadza midziyo yekurapa inofanira kugadzirwa kuti mweya wabuda usvike pachiyero chekuburitsa usati waburitswa mumhepo. .

Dust collector imhando yemidziyo yekuparadzanisa zvimedu zvakasimba mugasi, iyo inoshandiswa kubvisa guruva muindasitiri yekufefetera mhepo. Hupfu uye zvicherwa zviri mumhepo zvinoburitswa kubva kune mamwe magadzirirwo ekugadzira (sekupwanya simbi, isiri-ferrous kunyungudutsa simbi, kugadzira zviyo, nezvimwewo) ndizvo zvinhu zvakabikwa kana zvigadzirwa zvinogadzirwa, uye zvine mutsindo mune zveupfumi kuzvishandisa patsva. Naizvozvo, muzvikamu izvi, vaunganidzi veguruva vari vaviri midziyo yekudzivirira kwezvakatipoteredza nemidziyo yekugadzira.

Dust vaunganidzi vanowanzoshandiswa mukufemesa uye kubvisa guruva masisitimu ndeaya: cyclone guruva muunganidzi, bhegi sefa, wet dust muunganidzi, electrostatic precipitator, nezvimwe.

Inowanzo shandiswa inokuvadza gasi nzira dzekurapa mumhepo masisitimu dzinosanganisira absorption nzira uye adsorption nzira. Nzira yekunyura ndeye kushandisa mvura yakakodzera semushonga wekubata nemhepo ine magasi anokuvadza, kuitira kuti magasi anokuvadza anotorwa neanomwisa kana kuti kemikari anopindirana neanonyudza kuti ave zvinhu zvisingakuvadzi. Iyo adsorption nzira ndeyekufefetera midziyo Dongguan kufefetera midziyo

Shandisa zvimwe zvinhu zvine hombe adsorption simba se adsorbents kushambadza magasi anokuvadza. Activated carbon ndeimwe yeanonyanya kushandiswa adsorbents muindasitiri. Iyo adsorption nzira yakakodzera kurapwa kweanokuvadza yakaderera-concentration magasi anokuvadza, uye iyo adsorption inoshanda inogona kuva pedyo ne100%. Nekuda kwekushaikwa kwehupfumi uye hunoshanda nzira dzekurapa kune mamwe magasi anokuvadza, mhepo isina kurapwa kana isina kukwana inobatwa inogona kuburitswa mudenga nemachimney akakwirira seyekupedzisira sarudzo. Iyi nzira inonzi high-altitude discharge.

Air heaters Munzvimbo dzine kutonhora kwakanyanya, hazvibviri kutumira zvakananga mhepo inotonhora yekunze muimba, uye mhepo inofanira kupisa. Kupisa kwepamusoro kunowanzo shandiswa kupisa mweya nemvura inopisa kana chiutsi semhepo inopisa.

Kana mhepo yeketeni yemhepo yaburitswa kubva paburi rakatsemuka pane imwe sipidhi, inoumba jeti rendege. Kana midziyo yekufemesa muDongguan yakamisikidzwa iine mhepo yakatsemuka kuti inhale kuyerera kwemhepo iyi, kuyerera kwemhepo kwakafanana neketeni kunogadzirwa pakati pekufuridza nemhepo. Mudziyo unoshandisa manyawi emhepo inovhuvhuta pachayo kugura mhepo kumativi ose ekuyerera kwemhepo unodaidzwa kuti keteni remhepo. Keteni remhepo rakaiswa pamusuwo nekubuda kwechivako rinonzi keteni remusuwo remhepo. Chidzitiro chemhepo chegonhi chinogona kudzivirira kunze kwemhepo, guruva, zvipembenene, mhepo yakasvibiswa uye kunhuwa kubva mukamuri, kuderedza kupisa (kutonhora) kurasikirwa kwechivako, uye hakutadzisi kufamba kwevanhu nezvinhu. Maketeni emhepo egonhi ave achishandiswa zvakanyanya muzvirimwa zveindasitiri, mafiriji, zvitoro zvedhipatimendi, mabhaisikopo, nezvimwewo apo vanhu nemotokari vanowanzopinda nekubuda. Muzvivakwa zvehurumende, iyo yekumusoro mhepo yekupa mhando ine yekumusoro mhepo yekupa ndiyo inonyanya kushandiswa, uye yakaderera mhepo yekupa mhando uye yedivi rekutumira mhando inonyanya kushandiswa muzvivakwa zveindasitiri. Maketeni emhepo anoshandiswawo kudzora kupararira kwezvinosvibisa munzvimbo dzenzvimbo. Zvishandiso zvinoshandiswa pachinangwa ichi zvinonzi air curtain partitions kana kuvhuvhuta uye kusveta exhaust hoods. Kugamuchirwa kwakawanda. Kana ichienzaniswa neyechinyakare exhaust hood, ine simba shoma rekushandisa uye nani kusvibisa kusvibisa maitiro pasina kutadzisa kugadzirwa.
