Description

Felt type sludge dewatering device {SLUDGE DEHYDRATE SYSTEM OF FELT TYPE}

The present invention relates to a felt-type sludge treatment apparatus in which a high-pressure dewatering belt made of felt is attached to a high-pressure transfer dehydration unit, and more specifically, a flocculated sludge is dropped into a dewatering-transfer unit installed in front of the pressure-transfer dewatering unit and sludge at its own weight. The present invention relates to a felt-type sludge dewatering apparatus configured to drain water first, and to be fed to a pressure feed dewatering unit, transferred between the compression rollers, and then compressed and dehydrated.

Conventional sludge dewatering apparatus is mainly used double belt press type dewatering apparatus for placing the pressure roller in a multi-stage in the support frame chamber and winding the dewatering belt on the outer surface to inject sludge between the dewatering belt and dewatering.

In the conventional dehydration device as described above, the filtrate is drained while storing and supplying various sludge to be treated as a pretreatment process, and the precipitated sludge is supplied together with the polymer flocculant to the sludge stirring tank and stirred with dehydrator while stirring. The sludge dewatering device is constructed to transfer the sludge and press the belts on both sides through the gravity part and the gravity part to remove the primary water by compressing the water in the sludge to remove moisture and discharge the sludge. However, its composition is complicated, and the water extracted during the pressurization process is absorbed back into the sludge, which has a low dehydration effect.

The present invention is to develop a more effective sludge dewatering apparatus by improving the conventional problems as described above will be described based on the accompanying drawings.
