KubDrying
Thermal sludge ziab yog txheej txheem ntawm dewatering wastewater kho cog sludge siv tshav kub. Lub tswv yim tseem ceeb tom qab thermal sludge kom qhuav yog kom evaporate dej los ntawm cov sludge los ntawm kev nthuav tawm nws mus rau qhov kub thiab txias, uas ua rau txo qis hauv ntim thiab nce hauv cov khoom khib nyiab.
Muaj ntau ntau hom thermal sludge dryers, suav nrog:
Cov tshuab ziab khaub ncaws ncaj qha
Cov tshuab ziab khaub ncaws ncaj qha yog cov tshuab ziab khaub ncaws uas siv kev sib cuag ncaj qha ntawm cov khoom qhuav thiab cov kwj ntawm cov roj kub kom tshem tawm cov dej noo. Cov pa roj kub feem ntau yog tsim los ntawm cov roj hlawv, xws li cov pa roj carbon monoxide, propane, lossis diesel, hauv chav combustion chamber. Cov tshuab ziab khaub ncaws ncaj qha feem ntau yog siv rau ziab cov ntaub ntawv xws li nplej, ntoo chips, minerals, thiab tshuaj, thiab lawv tuaj yeem ua haujlwm nyob rau hauv kev sib koom ua ke tam sim no lossis counter-tam sim no flow configurations. Thaum cov tshuab ziab khaub ncaws ncaj qha tuaj yeem muab cov thermal efficiency thiab cov nqi qis, lawv yuav tsis haum rau qee cov khoom siv hluav taws xob lossis cov khoom tawg.
Indirect hluav taws xob tshuab ziab khaub ncaws
Indirect-fired dryers yog cov tshuab ziab khaub ncaws uas siv cov phab ntsa rhuab los yog lub raj xa cua sov rau cov khoom siv qhuav, tsis yog kev sib cuag ncaj qha nrog cov kwj ntawm cov roj kub. Cov cua kub tuaj yeem tsim los ntawm cov roj hlawv, xws li hauv qhov cub, lossis los ntawm kev siv cov ncu lossis lwm cov kua thermal. Indirect-fired dryers feem ntau yog siv rau ziab tshav kub-sensitive los yog explosive cov ntaub ntawv, nrog rau cov ntaub ntawv uas yuav tsum tau ib tug high degree ntawm purity. Lawv tuaj yeem ua haujlwm nyob rau hauv kev sib koom ua ke tam sim no lossis counter-tam sim no ntws kev teeb tsa, thiab tuaj yeem tsim nrog ntau qhov cua sov thiab cua txias rau kev tswj qhov kub thiab txias. Indirect-fired dryers feem ntau muaj peev nyiaj ntau dua thiab cov nqi khiav lag luam piv rau cov tshuab ziab khaub ncaws ncaj qha, tab sis tej zaum yuav tsim nyog rau qee yam kev siv.
Nruas tshuab ziab khaub ncaws
Drum dryers yog cov tshuab ziab khaub ncaws uas siv lub nruas tig kom qhuav ntau yam khoom, suav nrog cov khoom noj khoom haus, tshuaj, thiab cov zaub mov. Cov khoom yuav tsum tau qhuav yog pub rau hauv lub nruas, qhov twg nws yog qhuav los ntawm kev sib cuag nrog lub nruas rhuab nto. Lub nruas feem ntau yog cua sov los ntawm chav dej, dej kub, lossis cov roj thermal, thiab cov khoom siv tuaj yeem cuam tshuam los yog nqa los ntawm cov fins sab hauv los txhim kho kev ua kom qhuav. Nruas tshuab ziab khaub ncaws tuaj yeem tsim nyob rau hauv ntau yam kev teeb tsa, xws li ib leeg lossis ob lub nruas, thiab tuaj yeem ua haujlwm nyob rau hauv hom sib koom lossis tam sim no. Lawv muab cov khoom siv siab thiab ua kom qhuav, tab sis yuav xav tau cov peev nyiaj ntau dua thiab cov nqi khiav lag luam dua li lwm hom tshuab ziab khaub ncaws.
Fluidized txaj dryers
Fluidized txaj tshuab ziab khaub ncaws yog cov tshuab ziab khaub ncaws uas siv lub txaj fluidized ntawm cov khoom kom tshem tawm thiab ziab cov khoom ua tiav. Lub txaj feem ntau yog ua los ntawm inert hais, xws li xuab zeb los yog alumina, thiab yog fluidized los ntawm cov pa kub los ntawm nws. Cov khoom yuav tsum tau qhuav yog pub rau hauv lub txaj fluidized, qhov chaw uas nws qhuav los ntawm kev sib cuag nrog cov khoom kub thiab roj. Fluidized txaj tshuab ziab khaub ncaws muab cov nqi siab ntawm cov cua sov thiab huab cua hloov pauv, ua rau kom qhuav sai thiab ua tau zoo. Lawv tuaj yeem ua haujlwm hauv batch lossis txuas ntxiv, thiab tuaj yeem tsim nrog ntau yam kev teeb tsa, xws li ntsug lossis kab rov tav orientations. Fluidized txaj tshuab ziab khaub ncaws feem ntau yog siv los ziab cov ntaub ntawv kub-sensitive lossis tsis yooj yim, xws li tshuaj, khoom noj, thiab tshuaj.
Thermal sludge drying yog ib txoj hauv kev zoo los ua kom qhuav, ruaj khov, thiab yooj yim tuav cov khoom. Nws yog feem ntau siv ua ke nrog rau lwm txoj kev ntawm sludge dewatering, xws li mechanical dewatering, kom ua tiav cov khoom kawg xav tau.
Txawm li cas los xij, thermal sludge ziab kuj tseem siv zog, thiab xav tau kev nqis peev tseem ceeb hauv cov cuab yeej siv thiab cov vaj tse. Nws kuj tseem tsim cov roj tsev cog khoom ntau heev, uas tuaj yeem ua rau muaj kev txhawj xeeb los ntawm ib puag ncig kev xav. Tsis tas li ntawd, qhov kub siab siv hauv thermal sludge kom qhuav tuaj yeem ua rau tsim cov khoom muaj txiaj ntsig zoo, xws li dioxins, uas yuav tsum tau ua tib zoo tswj xyuas kom ntseeg tau tias cov sludge qhuav muaj kev nyab xeeb rau kev pov tseg.
