Ama-Anaerobic Digester Ensini Ezingeni Eliphezulu Ye-Bolted Steel Yokukhiqiza Okuthuthukisiwe Kwama-Biogas Nengqalasizinda Yokuguqula Udoti Ube Amandla
Emikhakheni yokuphathwa kwamanzi angcolile kamasipala, ukwelashwa kwamanzi angcolile ezimbonini, kanye nokucubungula udoti wezolimo, i-anaerobic digestion iyinqubo ebalulekile yokunciphisa ivolumu, ukuzinza kwezifo, kanye nokutholwa kwamandla avuselelekayo. Ingqikithi yale misebenzi yokuguqula udoti ube amandla yi-anaerobic digester yensimbi eboshiwe—i-biological reactor ekhethekile eyenzelwe ukwenza lula ukubola okushukumisayo okwenziwa amagciwane ngokuphelele ngaphandle komoya-mpilo.
Ngokungafani nezindawo zokugcina izinto eziwuketshezi ezijwayelekile, i-anaerobic digester iphatha izinto ezilukhuni kakhulu, eziguquguqukayo, futhi ezilimaza amakhemikhali. Isakhiwo kumele sikwazi ukubekezelela ukushintsha okungapheli kwezinga lokushisa, siphakamise ingcindezi enkulu yangaphakathi eyenziwa ukuqoqwa kukagesi, sibekezelele ukuguguleka okunamandla kwamakhemikhali okuvela kumagciwane anama-organic acids, futhi sibekezelele ukugqwala okubangelwa amagciwane ngaphakathi kwendawo kagesi. Kubathuthukisi bamaphrojekthi, abaqeqeshi be-civil EPC, kanye nonjiniyela besitshalo, ukukhetha impahla yokugcina i-anaerobic kudinga ukuthi kungabikho mphumela wokuhluleka kwesakhiwo noma ukuvuza kukagesi.
Njengomhlaba wonke owenza izinto ezintsha ezihlobene nezinhlelo zokugcina ezakhiwe ngezimbazo kusukela ngo-2008, i-Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) yakha futhi yenze izixazululo zokubamba ezenziwe ngokwezifiso ezanelisa izidingo eziphakeme kakhulu zomhlaba zezimiso ze-bioenergy. Ngokusekelwa iminyaka engaphezu kwamashumi amathathu yokuhlangenwe nakho okuthuthukisiwe kokukhiqiza, i-Glass-Fused-to-Steel (GFS) Bolted Steel Anaerobic Digesters yethu enezimbazo ihlinzeka ngendawo yokuphendula ethembekile, engadingi ukunakekelwa okuningi eyenzelwe ukuthuthukisa ukubuyiswa kwe-methane.
1. I-Biochemistry yenqubo: i-Kinetics ye-Methanogenesis kanye ne-MIC Dynamics ye-Headspace
I-anaerobic digester yensimbi enezimbazo isebenza njengendawo yokucwenga ye-biochemical ethuthukisiwe, esiza izikhathi ezilandelanayo zokubola kwezinto eziphilayo:
Le biochemistry yethula izindlela ezimbili ezihlukene zokugqwala ezisongela ukuqina komzimba kwempahla:
● Isigaba Esiyisikhuluphala (Ukuhlasela Okuyisidakamizwa): Phakathi kwezinyathelo zokuqala ze-acidogenesis ne-acetogenesis, amagciwane akhethekile aguqula izinto eziyinkimbinkimbi zibe ama-monomers e-organic nama-volatile fatty acids. Le nqubo yehlisa i-pH matrix yoketshezi, idale indawo enesidakamizwa ehlasela kakhulu ukhonkolo olunezingqimba futhi ikhuphe izendlalelo zopende ezisetshenziswa ensimini.
● Isigaba Segesi (I-MIC Ye-Headspace): I-biogas eyenziwe ithwala imikhondo yomswakama negesi ye-hydrogen sulfide (H2S). Ku-headspace evalekile ngaphezu komugqa wamanzi, le gesi isabela nomswakama womoya kanye nemikhondo ye-oxygen ezindongeni zezitsha. Amagciwane okhipha i-sulfur ahlala kulezi zindawo adla igesi ukuze akhiqize i-sulfuric acid (H2SO4) egxilile, okubangela i-Microbial-Induced Corrosion (MIC) ebucayi.
I-Center Enamel ibhekana nalezi zinsongo ezimbili zamakhemikhali ngokusebenzisa ubuchwepheshe obuseqophelweni eliphezulu bamapaneli engilazi ashunqulwe efektri, ahlala engashintshi lapho evezwa ezindaweni ezinama-acidic kuze kufike ku-pH 1.0.
2. Isayensi Yezinto Ezithuthukisiwe: Izinzuzo Zensimbi Ehlanganiswe Ngama-bolts ye-GFS
