Yini i-Molasses Silo: Ukugcinwa Kwe-Viscous, Fermenting Liquid Bulk
I-silo ye-molasses iyisitsha sokugcina esiyisilinda somuthi omanzi, onobukhulu obuphezulu, ovutshelwayo: idinga isisekelo esizokhipha uketshezi olujiyile ngokuphelele, ukushisisa noma ukulandelela ukugcina i-viscosity isebenza, ukunyakazisa ukuvimbela ukuhlangana nokuvutshelwa, kanye nendlela yokukhipha i-CO₂ ekhiqizwa uketshezi olugciniwe. I-silo yensimbi ehlanganiswe nengilazi inikeza ingaphakathi elingenzi lutho ku-pH 1–14 ngongqimba lwe-enamel oluhlanganiswe ku-820–930 °C, olungu-0.25–0.45 mm ubukhulu futhi luhlolwe nge-spark ku-1500 V DC, kuyilapho ingaphakathi le-epoxy elihlanganiswe nge-fusion-bonded ku-180–280 µm ngokwe-AWWA C550 kuyindlela ehlukile yomsebenzi onolaka noma oshintshanayo.
Indawo yokukhiqiza utshwala, isitshalo semvubelo noma umkhiqizi wokudla ogcina i-molasses uyazi ukuthi lena akuyona ithangi lamanzi. I-molasses iminyene, inamathela, ijwayele ukuvutshelwa lapho inomoya, futhi ishiya insalela eqinile kunoma iyiphi indawo eyithintayo lapho yoma. Lezo zinto ezintathu zilolonga yonke i-silo: phansi kufanele kukhiphe uketshezi olujiyile kuze kufike cishe ku-zero, ingaphakathi kufanele kugezeke kube yindawo ehlanzekile, ithangi kufanele libhekane negesi ekhiqizwa ukuvutshelwa, futhi esimweni sezulu esibandayo uketshezi kufanele kugcinwe kufudumele ngokwanele ukuze lunyakaze. Uma kukhona okungalungile kulezi, i-silo iba inkinga yokuhlanza ehambisana nokulahlekelwa umthamo.
I-Viscosity, ukukhipha amanzi kanye ne-bottom geometry
Uketshezi olunamathelayo alunakuzilinganisa ngokwalo, ngakho-ke phansi kwakhiwe njengomshini wokudonsa amanzi. I-molasses ithulula futhi izilinganise kancane kakhulu kunamanzi, futhi uma isipholile iba mncane kakhulu, okusho ukuthi iphansi eliyisicaba elinezimbobo zokuphuma lishiya insalela enkulu eqina epuletini. Impendulo ejwayelekile iwukuthi kube nomgodi ongaphansi oyisicone othambekele ngokwanele ukuthi uketshezi lugijime luye endaweni eyodwa yokuphuma, noma ifaneli engajulile enomjikelezo wokumpompa ophinda ujikelezise umkhiqizo usuka endaweni yokuphuma ubuyele phezu kwendawo ukuze ulinganise. Indawo yokuphuma kanye nepompo kufanele zilinganiswe ngokwesimo esibandayo nesinamathelayo hhayi esifudumele, futhi ipompo kufanele ibe uhlobo olukhipha ngamandla olunensiza yokugcina, ngoba ipompo ye-centrifugal ku-molasses eqinile ilahlekelwa ijika layo elijwayelekile tambe lapho isitshalo siyidinga. Iphuzu eliphansi lidinga futhi umugqa wokugeza noma wokuhlanza ukuze into yokugcina kube ngamanzi omthombo wawo, hhayi isincibilikisi, futhi ukuze ithangi likwazi ukukhishwa ukuze lihlolwe ngaphandle komsebenzi wamasonto wokwenza ngesandla.
I-Fermentation gas, ukukhipha umoya kanye ne-atmospheric boundary
I-molasses egciniwe iyabila uma inokumoya-mpilo nokushisa, futhi i-CO₂ kufanele iye endaweni ephephile. Ngisho ithangi elivalwe kahle lizobona igesi evela kunoma yimuphi umoya ongena ngesikhathi sokugcwalisa, ngakho i-silo idinga isikhala somoya esilinganiswe nezinga lokugcwalisa, indlela yokukhulula umfutho wokubila, kanye ne-flare noma i-scrubber lapho isitshalo sinayo; ingcindezi ehilelekile iphansi, cishe ngamakhilopaskali ambalwa, okugcina i-silo nophahla lwayo ngokukhululekile endaweni yomoya womkhathi. Lapho inhloso iwukunciphisa ukubila, impendulo yokuklama iwukugcina uketshezi lunyakaza, ukugcina isikhala esingaphezulu sincane noma singenamoya, ukugwema ukungenisa umoya endaweni yokugcwalisa, nokugcina i-molasses ifudumele futhi ingenayo imithwalo yemvubelo eqala ukubila. Lapho ukubila kufuneka — emsebenzini we-fermenter yase-distillery — indlela efanayo yegesi iba indawo yokuqoqa, futhi ithangi liba ingxenye yenqubo enomugqa wegesi, idivayisi yokukhulula ingcindezi kanye ne-flame arrestor.
Ukushisa, ukugovuza kanye nokulawula izinga lokushisa
Izinga lokushisa liyingxenye yenqubo la, hhayi into yokunethezeka. I-molasses ijiyela kakhulu njengoba iphola, ngakho-ke esimweni sezulu esibandayo ithangi lifakwa ijakethi yokushisisa, amakhoyili angaphakathi noma umjikelezo wamanzi afudumele, okulinganiselwe ukulahlekelwa ukushisa okulindile hhayi okwesikhashana. Ukushisisa kuphela akwanele: ithangi elishisisiwe elinomthamo omile lakha ungqimba oluzinze kanye nezindawo ezishisa kakhulu zendawo ezikhuthaza ukuvutshelwa odongeni, ngakho-ke ukushisisa kuhambisana nokujikeleza — noma i-loop yepompo noma isixhumi esibonakalayo esisheshayo — esigcina umzimba wonke usezingeni lokushisa elifanayo. Inkonzo yebhayoloji ye-mesophilic, lapho isebenza khona, isebenza ku-35–38 °C; ekugcinweni umgomo umane uyinga lokushisa lapho uketshezi luthela ngokuthembekile ngokusebenzisa umgudu wokuphuma kanye nepompo. Ukunyakaza kokushisa nakho kufanele kwakhelwe ithangi eliboshiwe: igobolondo elishisisiwe liyakhula futhi linciphe emjikelezweni, ngakho-ke i-gasket ehlanganyelwe nokubekezelelana kwebhawodi, umsele kanye nemininingwane ye-anchor kufanele kucaciswe ukushintsha kwezinga lokushisa, hhayi indawo ezungezile.
