Sludge ziab tuaj yeem tshem tawm cov dej sib txuas, dej capillary thiab feem ntau ntawm cov dej txuas nrog hauv cov sludge. Raws li kev sib cuag hom ntawm sludge thiab cua sov nruab nrab, sludge ziab tuaj yeem muab faib ua indirect drying thiab ncaj qha ziab. Indirect drying yog dav siv vim nws qhov zoo ntawm cov hmoov av tsawg dua thiab tsis muaj kuab paug los ntawm qhov nruab nrab kub. Tam sim no, feem ntau siv indirect drying khoom feem ntau muaj xws li teb disc tshuab thiab paddle tshuab.
Cov khoom siv los ntawm paddle dryers muaj xws li:
Chemistry: ntsev, Catalysts, Brominated Organics, Cellulose, Starch
Petrochemical: Khoom Devolatilization
Polymers thiab yas: polypropylene, polycarbonate, polyphenylene sulfide, polyester, PTA
Gourmet: hmoov, dej haus hmoov, khoom xyaw confectionery, nqaij khoom
Minerals thiab hlau: hlau hmoov, hlau carbonates, sulfates thiab hydroxides
Nyob rau hauv qhov tseeb sludge kev kho mob, lub peev xwm ua ntawm lub tshuab ziab khaub ncaws yog ze ze rau kev ua haujlwm ntawm cov khoom siv thiab cov khoom ntawm cov sludge. Txhawm rau kom ua tiav kev ua haujlwm siab dua, peb yuav ua ntej txheeb xyuas qhov cuam tshuam txog kev ua haujlwm ntawm lub tshuab ziab khaub ncaws:
Txhawm rau txhawm rau txiav txim siab qhov ntim ntawm cov khoom qhuav ntawm lub tshuab ziab khaub ncaws, nws tuaj yeem muab xam rau hauv kev suav ntawm nws lub ntsiab conveying muaj peev xwm, xam lub zog conveying, thiab xam lub zog ntawm txhua feem. Ntawm chav kawm, thawj thiab foremost yog xam ntawm lub conveying muaj peev xwm. . Tsawg chav siab lossis dej cov ntsiab lus, tsis zoo nplawm thiab sib xyaw ua haujlwm, cov khoom siv qis khiav ceev, cov khoom siv tsis tsim nyog hauv lub tshuab, dej tsub zuj zuj hauv lub paddle lossis hollow ncej, cov dej siab hauv cov khoom noj, ua raws li phab ntsa lossis scaling ntawm cov cua sov nto, Cov dej noo tsis tso tawm kom zoo, cov dej condensed rov qab mus rau lub tshuab ziab khaub ncaws, thiab lub paddle lossis lub tsho xau cua thiab dej.
