The invention discloses a novel
sludge drying processing device, and belongs to the technical field of
environmental protection equipment. The novel
sludge drying processing device comprises a feeding
machine, an
air blower, an
air heater, a diffuser, air flow dryers, a
cyclone dryer, a
cyclone separator, a dust remover, and an induced draft fan; air is heated by the
air heater to a temperature higher than 100 DEG C, is delivered into the diffuser, and is mixed with
dewatered sludge so as to obtain a hot air
sludge flow, wherein
water content of the
dewatered sludge is controlled to be 80%, and the
dewatered sludge is delivered into the diffuser via the feeding
machine, and is smashed using the diffuser; sludge in the hot air sludge flow is dried using the air flow dryers and the
cyclone dryer, dried air sludge flow is delivered into the cyclone separator so as to obtain dried sludge with a
water content less than 5% via separation; hot air and dried sludge dust are delivered into the dust remover; and dried sludge dust is discharged via the bottom of the dust remover. The novel sludge
drying processing device is used for processing sludge using a man-made heat source, deep
dewatering is realized,
thermal treatment effect is achieved, the activity of microorganisms in sludge are inhibited, and the obtained dried sludge can be taken as fertilizers, building materials, and the like.
