Yini Ithangi Lokugaya Indle?
Indle yendle yenziwa yingxenye ebizayo yesitshalo sokuhlanza amanzi angcolile. Kufanele ijiyiswe, iqiniswe, ikhishwe amanzi futhi ilahlwe, futhi ithani ngalinye libiza imali esigabeni ngasinye. Ukugaya yisigaba esisodwa esibuyisela okuthile: kubhubhisa ingxenye enkulu yezinto eziphilayo eziguquguqukayo, kubulala amagciwane, kususa iphunga, kuthuthukisa ukukhipha amanzi, futhi kukhiqiza i-biogas engashisa i-digester ngokwayo futhi ikhiqize amandla.
Ithangi le-digester lendle yisitsha esenza lokho kwenzeke - isiphenduli esishisayo, esixutshiwe, esingangenisi igesi esigcina indle amaviki kunokuba amahora. Yakhiwe yi-Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), ama-digester e-glass-fused-to-steel anikezwa aphelele nophahla, ukushisa, ukuxuba nokuphatha igesi, ngoba ithangi liyingxenye yesiphenduli kuphela.
1. Yini Eyenziwa Yi-Sludge Digester?
Iqinisa indle ngaphandle komoya: amabhaktheriya aguqula izinto eziphilayo eziguquguqukayo zibe yi-biogas, okushiya insalela encishisiwe, eqinisiwe, ekwazi ukukhipha amanzi.
· Ukubhujiswa Kwezinto Eziqinile Eziguqukayo: Ngokuvamile amaphesenti angama-40-50 ezinto eziqinile eziguqukayo aguqulwa abe igesi, okunciphisa ngqo isisindo esilahlwayo.
· Ukukhiqizwa Kwe-Biogas: Igesi icishe ibe ngamaphesenti angama-55-65 e-methane, futhi isetshenziselwa ukushisa, ukushisa okuhlanganisiwe namandla, noma ukuthuthukiswa ibe yi-biomethane.
· Ukuncishiswa Kwama-Pathogen: Ukugcinwa kwe-mesophilic ezingeni lokushisa kunciphisa kakhulu inani lama-pathogen; ukusebenza kwe-thermophilic noma i-pasteurisation kufinyelela amazinga aphezulu.
· Ukuncishiswa Kwephunga Nezinto Ezihambayo: Indle ewumbiwe ayinuki kakhulu futhi ayikhangi izinto ezihambayo njengodaka oluhlaza.
· Ukuthuthukiswa Kokukhipha Amanzi: Ukugaya kushintsha izici zokubopha amanzi zodaka, ngokuvamile kuthuthukisa ukusebenza kokukhipha amanzi futhi kunciphise isidingo se-polymer.
2. Yiziphi Izakhiwo Eziyinhloko?
Izinqumo ezintathu zichaza isitshalo: isimo sokushisa, inani lezigaba, nendlela i-sludge exutshwa futhi ishisiswa ngayo.
· Ukugaywa kwe-Mesophilic: Kusebenza ku-35-38 degrees Celsius, kuqinile futhi kuyabekezelela ukuphazamiseka, futhi kuyindlela esetshenziswa kakhulu ye-sludge kamasipala.
· Ukugaywa kwe-Thermophilic: Kusebenza ku-50-55 degrees Celsius, kucubungula ngokushesha futhi kufinyelela ukubulawa kwamagciwane amaningi, ngenani lokushisa okuphezulu kanye nokungazinzi okuphansi.
· Isigaba Esisodwa uma Kuqhathaniswa Nezigaba Ezimbili: Izinhlelo zezigaba ezimbili zihlukanisa ukwakheka kwe-asidi nokwakheka kwe-methane futhi ngokuvamile zifinyelela ukubhujiswa okuphezulu kwezinto eziqinile eziguquguqukayo ngevolumu efanayo iyonke.
· Izinga Eliphezulu uma Kuqhathaniswa Nejwayelekile: Ama-digester ezinga eliphezulu ahlanganiswa futhi afudunyezwa ngokuqhubekayo, okunikeza isikhathi sokugcina esifushane kakhulu kunamathangi ajwayelekile angahlanganisiwe.
· Ukuhlanganiswa Kwezinto Zokudla: Ukugaywa ngokuhlanganyela nokudla okulahlwayo noma amafutha, uwoyela namagrisi kukhuphula kakhulu isivuno segesi futhi kuvame kakhulu.
3. Yini Ehamba Nethangi?
I-digester iyisistimu: igobolondo, uphahla, ukufudumeza, ukuhlanganisa, ukuphathwa kwegesi nemishini yokuphepha, konke kwakhiwe ndawonye.
· Igobolondo Nophahla Olungavuzi Gesi: Igobolondo lensimbi eliboshiwe elivaliwe elinophahla olungaguquki nedome yegesi, noma isigcini segesi se-membrane sangaphandle.
· Ukushisa Nokuvikela: Igobolondo elivikelwe eline-cladding, kanye nokushintshana kokushisa kwangaphakathi noma kwangaphandle nokulawulwa kwezinga lokushisa.
· Ukuxuba: Ukubuyiselwa kwegesi, izixubi ezisemaceleni noma isixubi se-draft-tube, okukhethwa ngokuya ngokuqukethwe kwezinto eziqinile kanye nokuma kwejiyometri.
· Ukuphathwa Kwegesi Nokuphepha: Indawo yokuphuma kwegesi, izicupho ze-condensate, ukukhululeka kwengcindezi ne-vacuum, izivimbeli zomlilo kanye nokuqapha igesi.
· Amathuluzi Okulinganisa Nokulawula: Izinga lokushisa, izinga, ingcindezi, ukugeleza kwegesi, ukwakheka kwegesi kanye ne-pH noma ukuqapha i-volatile fatty acid njengezimpawu zenqubo.

Isiqinisekiso Sobunjiniyela Nokwesekwa Kwephrojekthi
Wonke amathangi alethwa yiShijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) aklanywa ngokuhambisana ne-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomthwalo wegobongo, uphahla kanye nama-nozzle, ahlanganiswa ku-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 ne-ISO 45001, ahlolwa nge-holiday test ku-1500 V kulo lonke ubuso, futhi ahlanganiswa ngamabhawudi e-Grade 8.8 kanye ne-sealant eqinisekiswe umkhiqizi. Amaphakethe e-digester afaka imidwebo yokuxhumana kwenqubo, incazelo yokufaka insulators nokushisa, ukuhlelwa kokuxuba, ukuphathwa kwegesi kanye namadivayisi okuphepha, kanye nokuqaliswa nokuqeqeshwa kwabasebenzi.
Imibuzo Evame Ukubuzwa (FAQ)
Yini eyenziwa yi-anaerobic digestion ku-sludge?
Iyasimamisa. Amabhaktheriya abola izinto eziphilayo ezingenasimoya, acekele phansi cishe amaphesenti angama-40-50 azo, akhiqize i-biogas, anciphise amagciwane nephunga, futhi athuthukise ukukwazi ukukhipha amanzi ku-digestate esele.
I-sludge digester isebenza kuphi ngezinga lokushisa?
Ama-mesophilic digester asebenza ku-35-38 degrees Celsius futhi ayiwona avame kakhulu; ama-thermophilic digester asebenza ku-50-55 degrees Celsius acubungula ngokushesha futhi abulala amagciwane amaningi kodwa adinga ukushisa okwengeziwe futhi awakwazi ukubekezelela ukuphazamiseka.
Uyini umehluko phakathi kwe-primary digestion ne-mixed sludge digestion?
I-sludge eyinhloko iyabola kalula futhi inikeza isivuno esiphezulu segesi ngekhilogramu yezinto eziqinile eziguqukayo. I-sludge exutshiwe - eyinhloko kanye ne-waste activated sludge - ikhiqiza igesi ephelele eningi ngoba kukhona okokudla okuningi, kodwa ingxenye ye-waste activated inzima ukuyihlukanisa ngaphandle kokwelashwa kwangaphambili.
Yimiphi imishini edingwa yithangi le-digester?
Igobolondo elingavumi igesi nophahla, ukufakwa kwe-insulation nokushisisa ngokulawula izinga lokushisa, imishini yokuxuba, ukuqoqwa kwegesi ngezicupho ze-condensate, ukukhululeka kwengcindezi ne-vacuum, izicishamlilo, kanye nezinsimbi zokulinganisa izinga lokushisa, izinga, ingcindezi, ukugeleza kwegesi nokwakheka kwegesi.
