Biogas ikukula kukhala yamtengo wapatali kwambiri ngakhale mafuta akutha. Ili ndi hydrogen sulfide (H₂S) yomwe imawononga kwambiri, yomwe imakhudzana ndi zinthu zachitsulo monga mapaipi, ma valve ndi zida zoyaka. Izi zimakhala zovulaza mphamvu ya makina ndi moyo wa zida.
Kuchotsa sulfurization ndi njira yabwino yochepetsera kuwononga chilengedwe pochepetsa kutulutsa kwa sulfure dioxides, komwe ndiko kuyambitsa mvula ya asidi ndi kuipitsidwa kwa mpweya. Kuchotsa sulfurization ndi njira yofunikira kuti ikwaniritse malamulo okhwima okhudza chilengedwe. Kuphatikiza apo, kumathandizira kuti kuyaka kugwire bwino ntchito poyatsa bwino, kukonza mphamvu zomwe zimatulutsa komanso kuchepetsa ndalama zogwirira ntchito.
Mavuto mu Kuchotsa Mafuta a Biogas Mwachikhalidwe
Pali mavuto akuluakulu omwe alipo pakusintha kwa biogas monga, kuyeza mochedwa, zolakwika pamanja, kuchuluka kwa ogwira ntchito komanso nkhawa zachitetezo. Tiyeni tikambirane nkhani zomwe zili pamwambapa imodzi ndi imodzi tsopano.
Kuyesa ndi manja nthawi ndi nthawi ndiyo njira yayikulu yowunikira kuchulukana kwa madzi. Komabe, kuchulukana kwa madzi oyeretsera sulfur kumatha kusiyana pakapita nthawi, zomwe zimapangitsa kuti zolakwika zazikulu zisachitike chifukwa cha kufulumira kwadzidzidzi kapena kuchepa kwa mphamvu ya madzi oyeretsera sulfur. Kuyeza kochedwa kumalepheretsa ogwiritsa ntchito kupeza mavuto ndikuwathetsa nthawi yake.
Kugwiritsa ntchito pamanja popereka zitsanzo ndi kusamutsa mwayi wopuma chifukwa cha zolakwika. Mwachitsanzo, madzi osungunuka amatha kuchitapo kanthu ndi mpweya kapena kuipitsidwa ndi zinthu zosafunika, zomwe zimapangitsa kuti muyeso ukhale wolakwika. Kuphatikiza apo, kuwerenga kosadalirika kungayambitsidwe ndi ngodya ya wowonera, thovu mu madziwo kapena kusintha kwa chilengedwe.
Kutenga zitsanzo ndi kuyeza pogwiritsa ntchito manja nthawi zambiri kumawonjezera ntchito zambiri komanso ndalama zambiri zogwirira ntchito, makamaka m'mafakitale akuluakulu oyeretsera sulfur omwe ali ndi malo ambiri oyezera. Ndipo ogwira ntchito omwe akukumana ndi zinthu zoopsa kuchokera ku zakumwa zoyeretsera sulfur nthawi zambiri amakumana ndi mavuto azaumoyo mpaka pamlingo winawake. Kuphatikiza apo, kugwira ntchito pafupipafupi m'malo omwe muli biogas yoyaka moto kumatha kuyambitsa magetsi osasinthasintha komanso ngakhale zipsera.
Ntchito za Chiyeso cha Kuchuluka kwa Madzi
Mu njira zochotsera mpweya wa biogas, ma metre ochulukirachulukira pa intaneti amachita gawo lofunikira kwambiri popititsa patsogolo magwiridwe antchito, chitetezo, komanso kutsatira malamulo okhudza chilengedwe. Nayi ntchito zawo zazikulu:
- Kuwunika Kuchuluka kwa Madzi Osungunuka
Mu biogas yonyowa, yankho la alkaline limagwiritsidwa ntchito kuchotsa hydrogen sulfide (H₂S) kudzera mu kukhudzana ndi countercurrent. Kuchuluka kwa madzi osungunuka kumagwirizana ndi kuchuluka kwake, komwe ma online density meters amatha kuyang'anira nthawi yeniyeni. Izi zimathandiza ogwiritsa ntchito kusunga kuchuluka kwa madzi moyenera, kuonetsetsa kuti H₂S imachotsedwa bwino komanso kuti njirayo ikhale yokhazikika. - Kukonza Mikhalidwe Yochitira Zinthu
Kuchuluka kwa madzi oyeretsedwa kumasintha pamene zinthu zoyambitsa matenda zikugwiritsidwa ntchito ndipo zinthu zimapangidwa panthawi ya mankhwala. Potsatira kusiyana kwa kuchuluka kumeneku, mita yoyeretsedwa pa intaneti imapereka chidziwitso cha momwe zinthu zikuyendera komanso momwe zimagwirira ntchito. Ogwiritsa ntchito amatha kusintha magawo monga kutentha, kuthamanga, ndi kuchuluka kwa zowonjezera kuti awonjezere kuchuluka kwa madzi oyeretsedwa kuchotsedwa ndikuwonjezera magwiridwe antchito ochotsa sulfure. - Kulamulira Kukonza Madzi Otayira
Njira yochotsera sulfure imapanga madzi otayira okhala ndi sulfates yambiri ndi zinthu zina zoipitsa. Poyang'anira kuchuluka kwa madzi otayirawa, mita yoyezera kuchuluka kwa madzi otayira pa intaneti imathandiza kudziwa kuchuluka kwa zinthu zoipitsa, zomwe zimathandiza kusintha njira zochizira madzi otayira kuti akwaniritse miyezo ya chilengedwe. - Kuletsa Kutsekeka kwa Zipangizo
Mu njira monga kuyeretsa mpweya wonyowa (monga kugwiritsa ntchito njira za sodium carbonate), kufalikira kwa madzi kosakwanira kapena kuchulukira kosayenera kwa kupopera kungayambitse kutsekeka kwa nsanja zoyeretsa mpweya. Mamita oyezera kuchuluka kwa madzi pa intaneti amapereka chenjezo koyambirira pozindikira kusintha kwa kuchuluka kwa madzi, zomwe zimathandiza kupewa mavuto monga kuipitsidwa kapena kutsekeka kwa mabedi odzaza. - Kuonetsetsa Kuti Dongosolo Lili Lokhazikika ndi Chitetezo
Ndi mayankho enieni pa magawo ofunikira kwambiri, mita iyi imathandizira kugwira ntchito bwino kwa makina, kuchepetsa chiopsezo cha kuwonongeka kwa zida kapena kusokonekera kwa ntchito. Kuphatikiza apo, imachepetsa kukhudzidwa ndi zinthu zoopsa mwa kuchotsa kufunikira koyesa zitsanzo pamanja pafupipafupi m'malo omwe angakhale oopsa.
Zogulitsa Zovomerezeka & Ubwino Wofanana
Nambala 1 ya Meter ya Kulemera kwa Foloko
Ndi yabwino kwambiri pa matope ngati omwe amapezeka mu njira zonyowa zochotsera sulfur. Amapereka muyeso wokhazikika wa kuchuluka kwa madzi nthawi yeniyeni, ndipo ali ndi kuyika kosavuta mwachindunji. Kapangidwe kake kolimba kamachepetsa ndalama zokonzera ndikuwonjezera kudalirika kwa makina, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'mafakitale a biogas.
Kukonza Foloko Kachulukidwe Meter
Nambala 2 ya Akupanga Kachulukidwe Meter
Chidachi chimagwirizana ndi ntchito zosiyanasiyana, kuphatikizapo kupanga mankhwala. Kapangidwe kake kolimba, kugwirizana ndi madzi owononga, komanso kutulutsa deta ya digito kumapangitsa kuti chikhale chofunikira poyang'anira machitidwe ochotsera sulfur kuchokera ku biogas.
Nambala 3 ya Coriolis Flow Meter
Ngakhale kuti makamaka Coriolis flow meters, amathanso kuyeza kuchulukana molondola kwambiri mu njira zokhudzana ndi zakumwa zomwe zimakhala ndi kuchulukana kosiyanasiyana. Ndi odalirika pakuchotsa sulfurization ya biogas komwe kuwongolera molondola kwa momwe mankhwala amachitira ndikofunikira.
Yankho la biogas desulfurization liyenera kutsindika udindo wofunikira wa ma automation a mafakitale ndi kuwongolera molondola pakukonza njira. Mwa kugwiritsa ntchito zida zowunikira nthawi yeniyeni, monga inline density mita, mafakitale amatha kuyendetsa bwino kuchuluka kwa madzi osungunuka kuti atsimikizire kuti magwiridwe antchito ndi kukhazikika kwa dongosolo. Izi sizimangoletsa dzimbiri ndi kutsekeka kwa zida komanso zimachepetsa ndalama zogwirira ntchito ndikuwonjezera kutsatira malamulo azachilengedwe pochepetsa mpweya woipa monga hydrogen sulfide.
Kuphatikiza apo, kugwiritsa ntchito njira yochotsera sulfur yokha kumachepetsa kwambiri mphamvu ya ogwira ntchito, kumawonjezera chitetezo, komanso kumaonetsetsa kuti ntchito ikuyenda bwino komanso modalirika. Kuwongolera molondola madzi ochotsera sulfur kumathandiza kukonza bwino momwe zinthu zimachitikira, zomwe zimapangitsa kuti mphamvu zigwiritsidwe ntchito bwino komanso kuti mpweya wa biogas ukhale wabwino. Kupita patsogolo kumeneku kukuyimira kupita patsogolo kwa mafakitale okhazikika, mogwirizana ndi zolinga zamakono zamagetsi komanso kusamalira zachilengedwe.
