Amathangi okugaya amanzi angcolile: Ukuklanywa kwe-Anaerobic Reactor nezinto
Ukuphathwa kwe-sludge kuyisizinda sezindleko esithulile kuzo zonke izimboni zamanzi angcolile, futhi ukugaya yisigaba esisodwa esingakuguqula kusuka ezindlekweni kube into yamandla. Umkhumbi osesizeni salokho kuguqulwa — ithangi lokugaya — kumele ubambe i-sludge eshisayo, egqwalayo, ekhiqiza igesi amasonto amaningi ngaphandle kokuvuza amanzi noma i-methane.
Ithangi lokucubungula udoti (digester tank) iyisitsha esishisayo, esixubile se-anaerobic — ngokuvamile sisebenza ku-mesophilic 35-38°C — lapho amagciwane abhubhisa khona ama-volatile solids angu-60-70% esludge ngesikhathi sokugcinwa kwezinsuku eziyi-15-25, kukhiqizwa i-biosolids ezinzile kanye ne-biogas equkethe i-methane engu-60-65%.
Yiziphi Izimo Zenqubo Okufanele Ithangi Le-Digester Likwazi Ukumelana Nazo?
Ukushisa okuqhubekayo nokugqwala: ukusebenza kwe-mesophilic 35-38°C noma i-thermophilic 50-55°C, lapho izindawo zangaphakathi zivezwa ku-biogas ene-H2S kanye ne-digestate ene-asidi — okudinga izinto zokumboza ezingenamaphutha nezingenazo izikhala.
Ukuqina kwegesi: umkhumbi kufanele ugcine i-methane ukuze kutholakale amandla nokuphepha; izicabha ezingaphezulu ezinama-membrane amabili noma izembozo ezihlala zikhona ezinokukhulula kwengcindezi zakhelwe ukugcina nokukhipha i-biogas ngendlela ebikezelwayo.
Imithwalo yokuxuba: izinhlelo zokuxuba ngemishini, ngokuphinda zisakaze noma ngegesi zilayisha ngokujikelezayo igobolondo nophahla, ngakho ukuqina kodonga nokuqiniswa kwemibhobho yizinto eziyisisekelo zokuklama.
Yiziphi Izinto Zethangi Ezenza Kahle Kakhulu Ekugayweni Kwenhlaka?
Ingilazi ehlanganiswe nensimbi (GFS): uqweqwe oluncibilikisiwe ngezinga lokushisa elingu-820-930°C linikeza indawo engasebenzi ye-pH 1-14 engathinteki ngamasulfide, futhi ukwakhiwa ngamabhawodi kuvumela umthamo wokugaya ukuthi ungezwe ngokukokwa kweringi ngeringi.
Insimbi eweldedwe ngopheya we-epoxy: indlela efakazelwe enezindleko eziphansi zokuqala yamadigester amakhulu anevolumu eyodwa, uma nje ikhwalithi yopheya nokulungiswa kwesikhathi esizayo kuhleliwe.
Ukhonkolo: indabuko yamadigester amakhulu omasipala, kodwa uvame ukugqwala endaweni yegesi futhi udinga ama-liner ukuze kungangeni umoya we-biogas.
Insimbi engagqwali: ukukhetha okuphezulu kwamadigester amancane abalulekile kanye nomsebenzi we-thermophilic lapho kufunwa khona ukumelana nokugqwala okuphezulu.
Amadigester Tanks Alinganiswa futhi Ahlelwa Kanjani?
Umthamo oqhutshwa ukugcinwa: ukulayishwa kwe-volatile solids kanye nokucekelwa phansi okuhlosiwe kubeka isikhathi sokugcina amanzi (hydraulic retention time) sezinsuku eziyi-15-25; umthamo wokusebenza we-digester ulandela ngqo ukugeleza kwe-sludge.
Ukuhlelwa kwesiteji: ukuhlanganiswa okuphelele, ukugeleza kwe-plug noma ukumiswa kwezigaba ezimbili kushintshanisa amandla okuxuba nokusebenza kahle kokuguqula, kukhethwa i-egg noma i-cylindrical geometry ngokufanele.
Ukuhlanganiswa okusizayo: amalophu okushisisa, ukulawulwa kwegwebu, ukugcinwa kwe-sludge egayiwe kanye nomthamo we-gasholder kumele kuklanywe nge-tank njengohlelo olulodwa ukuze ukutholwa kwegesi kusebenze kahle.
I-Matrix yokuqhathanisa: Izinketho zezinto zethangi lokugaya
Into | Ukumelana nokugqwala | Isikhathi sokusebenza | Ijubane Lokumisa | Izindleko Eziqhathaniswayo |
Ingilazi ehlanganiswe nensimbi | I-pH 1-14 engasebenzi, engangenwa sulfide | Iminyaka engu-30+ | Ishesha (ukubopha ngamabhawodi) | Emaphakathi |
Insimbi eweldedwe ngopheya we-epoxy | Phezulu, kuncike kopheya | Iminyaka engu-20-30 | Ihamba kancane (ukuwelda ensimini) | Emaphakathi |
Ukongkolo (olunomugqa) | Okumaphakathi; ubungozi besikhala segesi | Iminyaka engu-50 (ngokulungisa) | Ihamba kancane | Emaphakathi-Phezulu |
I-Stainless 304/316L | Kuhle kakhulu | Iminyaka engu-40+ | Emaphakathi | Phezulu |
I-digester ithola inzuzo yayo kuphela uma i-biology, isakhiwo kanye nokusingathwa kwegesi kuhlangene ekwakhiweni. Abasebenzi abaguqula i-sludge liability ibe yimali ye-biogas bakhetha njalo imikhumbi enama-coatings aphila kokubili ku-digestate ewuketshezi kanye nendawo enegesi enolaka — bese belinganisa isikhathi sokugcina ngokwe-chemistry yangempela ye-sludge hhayi ngokomthetho wokuqagela.
Imibuzo Ejwayelekile (FAQ)
Umbuzo 1: Ithangi lokugaya udoti lisebenza ezingeni lokushisa elingakanani?
Iningi lamathangi okugaya udoti lisebenza ngendlela ye-mesophilic ku-35-38°C, lilinganisa isivinini sokuguqula kanye namandla okushisisa. Ukusebenza nge-thermophilic ku-50-55°C kwandisa ukucekelwa kwezinto eziqinile eziguqukayo kanye nokubulala amagciwane kodwa kudinga ukushisa okwengeziwe kanye nethangi eliqinile — ngokuvamile i-GFS enesimbo se-2C noma ngaphezulu noma ithangi lensimbi engagqwali.
Umbuzo 2: Ithangi lokugaya likhiqiza malini igesi ye-biogas ngethani ngalinye lodoti?
Ngokucekelwa kwezinto eziqinile eziguqukayo okungu-60-70%, udoti oluhlaza ngokuvamile ukhiqiza cishe u-0.75-1.0 m3 we-biogas ngemitha cubic ngayinye yodoti ogayiwe kuye ngokugxila kokudla, ngemethane engu-60-65% — okwanele ukumboza u-50% noma ngaphezulu kwesidingo sikagesi sesikhungo esimaphakathi ngemva kokuguqulwa kwe-CHP.
Umbuzo 3: Ithangi lokugaya udoti lidinga isikhathi esingakanani sokugcina?
Amathangi e-mesophilic agaya ngokuphelele ngokuvamile agcina udoti izinsuku eziyi-15-25. Ngaphansi kwezinsuku eziyi-15, ukucekelwa kwezinto eziqinile eziguqukayo kwehla kakhulu; ngaphezu kwezinsuku ezingama-25, isivuno segesi esingeziwe asivamisile ukuthethelela umthamo wethangi owengeziwe.
Umbuzo 4: Ingabe amadigester kakhonkolo akhona angathuthukiswa?
Yebo — izinto ezivamile zokuthuthukisa zihlanganisa ama-liner angaphakathi e-GFS noma ensimbi engagqwali, uphahla olusha lwe-double-membrane gasholder kanye nokuxuba okuthuthukisiwe. Lapho umthamo hhayi isimo okuyiyona inkinga, ukwengeza i-bolted steel digester eceleni kwemikhumbi ekhona kuvame ukushesha futhi kushibhile kunokwakha kabusha ukhonkolo.
