Musiyano pakati peVPSA okisijeni jenareta uye PSA okisijeni jenareta

Kunyatsokwira, VPSA (yakaderera adsorption vacuum desorption) kugadzirwa kweokisijeni ndeimwe "mutsauko" wePSA kugadzirwa kweokisijeni, misimboti yavo yekugadzirwa kweokisijeni inenge yakafanana, uye musanganiswa wegasi unopatsanurwa nemusiyano mukukwanisa kwesefa yemamorekuru ku "adsorb" akasiyana gasi mamorekuru.Asi PSA kugadzirwa kweokisijeni kuri kuburikidza nepressurize adsorption, mhepo yekumanikidza desorption kuparadzanisa okisijeni.Iyo VPSA maitiro ekugadzirwa kweokisijeni ndeye desorption saturated molecular sieve pasi pevacuum mamiriro.

Kunyangwe ese ari maviri akavakirwa pamhepo seyakagadzirwa, musimboti wekugadzirwa kweokisijeni wakafanana.Asi mukunyatsoenzanisa, pane misiyano inotevera;

1. TheVPSA okisijeni jenaretainoshandisa blower kuwana mweya mbishi nekuidzvanya, nepo PSA okisijeni jenareta inoshandisa air compressor kugovera gasi.

2, Muchikamu chepakati - zeolite molecular sieve kusarudzwa, PSA oxygen generator inoshandisa sodium molecular sieve uye VPSA oxygen generator inoshandisa lithium molecular sieve.

3. Iyo adsorption pressure yePSA oxygen generator inowanzo 0.6 ~ 0.8Mpa, uye adsorption pressure yeVPSA oxygen generator ndeye 0.05Mpa uye desorption pressure ndeye -0.05Mpa.

4, PSA imwe chirimwa gasi kugadzira gasi kukwanisa kusvika 200 ~ 300Nm³/h, uye VPSA imwe chirimwa gasi kugadzira gasi kukwanisa kusvika 7500 ~ 9000Nm³/h.

5, VPSA inoenderana nePSA, yakaderera simba rekushandisa (kugadzirwa kwe1Nm3 okisijeni simba rekushandisa ≤ 0.31kW, kuchena kweokisijeni 90%, pasina kudzvanywa kweokisijeni), uye zvakanyanya kushamwaridzana.

6, Zvinoenderana nekugadzirwa kweokisijeni, simba rekushandisa zviyero uye mari yekusarudza PSA maitiro kana VPSA maitiro.

VPSA okisijeni jenareta kunyangwe iyo imwe chirimwa yekugadzira okisijeni yakakura, asi kushomeka kwayo ndeyekuti system midziyo yakanyanya kuoma, vhoriyamu yemidziyo yakakura (kuenzanisa neye cryogenic mudziyo ichiri diki), inotsigira uye utilities mamiriro ari kudiwa zvakanyanya. , ichatora nzvimbo yakakura, kazhinji haigone kugadzirwa mumudziyo.Uye inoda pa-saiti kuisirwa, kutumwa, kubva panguva ino chete.PSA ine zvimwe zvakanakira.
