Oily sludge yog cov pov tseg nyob rau hauv cov txheej txheem ntawm cov roj extraction, kev thauj mus los, roj refining thiab roj dej kho. Oily sludge kuj muaj ntau ntawm benzene series, phenolic tshuaj, tantalum, pyrene thiab lwm yam tshuaj tsw qab thiab tshuaj lom. Ib qho kev sib txuas ntawm oily sludge dehydration thiab high-temperature drying yog qhov tsis ncaj ncees lawm, uas tsis yog tsuas yog ua rau cov khoom siv pov tseg, ua rau huab cua lossis dej paug, tab sis kuj ua rau muaj kev phom sij rau cov neeg ua haujlwm noj qab haus huv.
Piv nrog cov tshuab ziab khaub ncaws los yog cov tshuab ziab khaub ncaws, hollow hniav tshuab ziab khaub ncaws muaj cua sov, tu, txias thiab lwm yam dej num, nrog rau kev sib khi zoo, tsis muaj plua plav thiab cov roj pov tseg hauv kev kho sludge, kev ua haujlwm siab thiab kev tiv thaiv ib puag ncig zoo.
Lub hollow hniav tshuab ziab khaub ncaws tau ua ntau yam tshiab ntawm cov yam ntxwv ntawm sludge nrog ntau hom, cov ntsiab lus dej siab, muaj zog viscosity, thiab cov ntsiab lus dej siab. Nws yog ib qho yooj yim rau lo rau hauv agglomerates thaum lub sij hawm ziab, ua rau cov nplaum nplaum thiab cov phab ntsa, ua rau kom qhuav efficiency tsawg. , cov nyhuv tsis zoo. Nws daws cov teeb meem no hauv cov txheej txheem sludge kom qhuav, ua tiav cov txiaj ntsig ntawm kev txo qis, tsis muaj kev puas tsuaj, kev ruaj ntseg, thiab kev pab cuam, thiab muab kev hloov pauv, ua haujlwm zoo, nyab xeeb, thiab ruaj khov sludge kho guarantees, ua rau kev siv cov sludge mus txog qib tshiab. qib.
Ib txoj hauv kev kom qhuav oily sludge nrog paddle desiccant, suav nrog cov kauj ruam hauv qab no:
(1) Cov roj sludge raug thauj mus rau hauv lub tshuab ziab khaub ncaws los ntawm lub twj tso kua mis;
(2) Dhau lub saturated chav rau hauv lub interlayer ntawm lub hollow paddle thiab lub chamber phab ntsa ntawm lub paddle tshuab ziab khaub ncaws kom indirect cua sov cov oily sludge;
(3) Tom qab oily sludge yog rhuab, dej thiab ib co volatile organic tebchaw evaporate rau cov roj, thiab cov roj nkag mus rau hauv lub scrubber;
(4) Tom qab cov roj tau dhau los ntawm lub tshuab ntxhua khaub ncaws, cov condensate feem ntau yog cov dej phwj tuaj, thiab cov roj rov qab los ntawm cov roj-dej sib cais, thiab cov dej nkag mus rau hauv qhov chaw kho dej; cov roj uas tsis yog condensable yog hlawv;
(5) Lub qhuav oily sludge yog tawm ntawm lub tshuab ziab khaub ncaws thiab khaws cia li qhuav oily sludge hauv hnab.
