VPSA okisijeni kugadzira michina

①: Nhanganyaya yemidziyo uye musimboti wekushanda
VPSA (Vacuum Pressure Swing Adsorption) mudziyo wekugadzira okisijeni, Chinese inonzi low pressure adsorption vacuum desorption oxygen kugadzira michina.Pasi pemamiriro epasi pasi, iyo nitrogen neokisijeni mumhepo zvinosvetwa mukati. Mushure mekunge adsorption yazara, molecular sieve inonyungudutswa pasi pemamiriro ekutsvaira, uye nitrogen inobudiswa kubva pachiteshi chekubuda.Iyo okisijeni inopinda muhurongwa hwekuchenesa.Iyo molecular sieve inoramba ichishambadzirwa uye yakaderedzwa kuti itenderere kuti ibudise yakakwira kuchena okisijeni (90-95%).
③: Equipment kuumbwa uye tekinoroji zviratidzo
VPSA okisijeni kugadzira michina inonyanya kuumbwa ne blower, vacuum pombi, inotonhorera, adsorption system, oxygen buffer tank, uye control system.
Iwo technical zviratidzo ndeaya anotevera:
◆ Chiyero chechigadzirwa: 100-10000Nm3 / h
◆Oxygen purity: ≥90-94%, inogona kugadziriswa muhuwandu hwe30-95% maererano nezvinodiwa nemushandisi.
◆Okisijeni simba rekushandisa: kana kuchena kweokisijeni kuri 90%, kushandiswa kwesimba kunoshandurwa kuita okisijeni yakachena ndeye 0.32-0.37KWh/ Nm3
◆Oxygen pressure: ≤20kpa (inogona kudzvinyirirwa)

◆Simba rekuvhura kwegore: ≥95%

PSA okisijeni kugadzira michina

①: Nhanganyaya yemidziyo uye musimboti wekushanda
PSA (Pressure Swing Absorption) okisijeni yekugadzira mudziyo, zita reChinese nderekumanikidza swing adsorption oxygen chizvarwa.Nheyo ndeyekuparadzanisa musanganiswa wegasi nekushandisa mutsauko mu "adsorption" kuita kwema molecular sieves kune akasiyana gasi mamorekuru.Inoshandisa mhepo sezvinhu zvakasvibirira, uye inoshandisa yakakwirira-inoshanda, yakakwirira-selectivity yakasimba adsorbent kusarudza adsorb nitrogen uye oksijeni kuparadzanisa nitrogen uye oksijeni mumhepo.Pasi peyakajairika tembiricha uye mamiriro ekumanikidza, iyo PSA yakakosha mamorekuru sieve inoshandiswa kusarudza kusviba senge nitrogen, carbon dioxide uye mvura mumhepo kuwana oxygen nekuchena kwepamusoro.
③: Equipment kuumbwa uye tekinoroji zviratidzo
PSA okisijeni kugadzira michina inonyanya kuumbwa nemhepo compressor, firiji dryer, deoiler, adsorption system, oxygen buffer tank, uye control system.
Iwo tekinoroji zviratidzo ndeaya anotevera↓↓
Kuchena: 93% + 2% (93% yemhando yakajairika)
Kudzvinyirira: ≥0.2Mpa
Dew point: <-40 ℃ (yakajairika kudzvanywa)
Kubuda: 3 ~ 200Nm3/h
