7. Mibvunzo Inowanzo bvunzwa: Mibvunzo Inowanzo bvunzwa Yekurega Kushanda

Kuti zvikubatsire kugadzira nekugadzirisa hurongwa hwako hwekuchengetedza gasi zvinobudirira,

heano mhinduro dzezvimwe zvemibvunzo inonyanya kutsvakwanezve spargers:

Ndeipi flow rate yakanakisisa yesparger?

Mwero wekufamba wakakodzera we sparger unoenderana nekushandiswa, saizi yetangi, uye gasi riri kushandiswa. Zvakakosha kuverenga mwero wekufamba unodiwa zvichibva pazvinhu zvakaita sehuwandu hwetangi, rudzi rwegasi, uye saizi yemabubble anodiwa kuti uve nechokwadi chekupararira kwegasi zvakanaka. Panguva yekuiswa kwesystem, mwero chaiwo wekufamba unofanirwa kuyerwa kuti usimbise kuti unoenderana nemitengo yakaverengerwa uye kuti ugone kuvandudza mashandiro.

Ndeipi saizi yepamusoro ye sparger pore ye oxygenation?

Kune vazhinjikushandiswa kweokisijeni yakanyungudutswa—sekuvirisa, kurima maruva, kana kurima masero—hukuru hwemaburi hwakakodzera hunowanzo kuve1 kusvika ku5 maikironiRudzi urwu runogadziramabhubhu madiki akanaka, izvo zvinowedzera nzvimbo yepamusoro uye zvinosimudzirakushanda zvakanaka kwekufambisa okisijeni (OTR).

Maburi matete = kunyudzwa kwegasi kuri nani = kushanda zvakanaka kwemaitiro.

Ndingashandisa mhepo yakamanikidzwa panzvimbo penitrogen here pakuderedza huwandu hwevhu?

Ehe,mhepo yakamanikidzwainogona kushandiswa kuderedza njodzi mumabasa akawanda, kunyanyakufefetera kana kuvirisaZvisinei, mumaitiro anokonzerwa neoxygen kana anaerobic (semuenzaniso, zvemagetsi, zvekudya, kana mishonga),nitrogen ndiyo inonyanya kufarirwanekuda kwekusashanda kwayo uye njodzi shoma yekusvibiswa.

Gara uchitarisa hunhu hwemhepo (isina mafuta/mvura) uye huwandu hwehutachiona kana ukashandisa mushonga usina utachiona.

Ndeupi musiyano uripo pakati pe sparging ne aeration?

Kunyange zvazvo zvose zvichisanganisira kuisa gasi mumvura,nzira nechinangwa zvinosiyana:

Kubvisa zvinhu zvisina kunyatsojeka uye zvinobudirira—zvakanakira masisitimu anoshanda zvakanyanya kana kuti akavharwa.

Ndingadzivirira sei sparger kuti isavhare?

Kuvharika kwechinhu kunowanzoitika muzvinhu zvine tunhu tudiki, viscous media, kana biofilm formation. Kudzivirira izvi:

*Shandisamaspager esimbi ane sintered emhando yepamusoro(semuenzaniso, simbi isina ngura ye316L)

*Iva nechokwadi chekutikusefa kusati kwaitwayegesi yemagetsi uye mvura

*Dhizaini yeKuenderana kweCIP/SIPuye bvumirakusunda musana

*Dzivisa nzvimbo dzakafa uye iva nechokwadi chekuisa zvakanaka

Kugara uchichenesa uye kugadzirisa zvinhu zvako kwakakosha kuti zvishande kwenguva refu.

Ndinofanira kushandisa flow rate yakadii pa sparger yangu?

Mwero wekuyerera kwemvura unoenderana nekushandiswa, rudzi rwegasi, saizi yetangi, uye zvinangwa zvehukuru hwemabubbleNzvimbo inowanzo tanga masisitimu mazhinji e bioreactor ndeiyi:

- 0.05 kusvika 0.2 vvm(huwandu hwegasi pahuwandu hwemvura paminiti)

Pakusarudza mwero wemvura wakakodzera, funga nezvekumhanya kwegasi pamusoro, iyo inoshandiswa kuona mwero wakakodzera wekuyerera kwegasi kuti pave nekupararira kwemabubble zvinobudirira uye kupararira kwemabubble zvinobudirira.

Kune masisitimu anoshanda zvakanyanya kana madiki ekugadzira ma laboratory, mwero wemvura yakaderera (0.01–0.05 vvm) ungave wakakwana. Kana paine gasi rinobvisa kana mhepo ine simba, mwero wemvura unogona kupfuura 0.5 vvm.

Kugadzirisa zvakanaka kwakavakirwa paOTR, kumanikidzwa kwemusana, uye zvinodiwa pakusanganisa.

Mhedziso: Dhizaini Inokosha Pakuderedza Kushandiswa Kwegasi Zvinobudirira

Kubudirira kwekubvisa gasi hakusi kungosarudza chinhu chaunoda kushandisa chete—kunongovakugadzira sisitimu inoenderana nezvinodiwa zvako chaizvoKubva pakusarudza rudzi rwesparger rwakakodzera uye saizi yemaburi kusvika pakuona kuti zvinhu zvakakodzera, kubatana, uye kuchena kwakakodzera,sarudzo yega yega yekugadzira inokanganisa zvakananga kushanda zvakanaka, kuchengetedzeka, uye kushanda kwenguva refu.

Muzvidzidzo zvazvino, simba remagetsi emakombiyuta raratidza kukosha kukuru pakugadzira nekugadzirisa dhizaini yemagetsi emagetsi. Kuwana chibvumirano chakanaka pakati pekuenzanisa simba remagetsi emakombiyuta nemhedzisiro yekuedza kwakakosha pakusimbisa nekuvandudza mashandiro emagetsi emagetsi mumagetsi-muchina.

Kana uri kushanda mubiopharma, kugadzirisa makemikari, kuvirisa, kana kurapwa nemvura, kuwedzera huwandu hwezvinhu zvakasara kunogona kutungamira ku:

* Nguva dzekukurumidza dzekuita

*Goho guru rezvigadzirwa

*Kuderedza kushandiswa kwegasi uye marara

*Kudzora maitiro kuri nani uye kugara kwenguva refu

Ndosaka zvichibatsira kushanda pamwe chete nemunhu ane ruzivoMugadziri we sparger weOEMseHENGKOIsu tinonyanya kugadzira zvinhu

in masparger esimbi anogadzirwa nesimbi yakagadzirwa nemaokoyakavakirwa kugadzirisa kumanikidzwa kwako kwakasiyana, kuyerera, uye kuenderana kwemakemikari
