Description

DEODORIZATION WATER DRYING EQUIPMENT [0002]

More particularly, the present invention relates to a water deodorizing dryer capable of improving sludge drying efficiency by allowing steam supplied from a steam supply unit to flow uniformly in a drum.

Conventionally, landfill or marine dumping method for sludge treatment is a treatment method which is being avoided due to secondary pollution. As an alternative to the landfill or marine dumping method, there is a sludge treatment method using microorganisms, but the sludge treatment method using the microorganisms has not been commercialized because of the technical development.

As a solution to such a situation, there is adopted a method in which high temperature steam is applied to the sludge to deodorize and dry the moisture of the sludge, and then the residue is recycled as compost or the like. Since the sludge generated in the wastewater treatment plant has a very high moisture content, if the sludge is treated by deodorizing and drying the moisture of the sludge, the problem of causing environmental pollution can be solved, and the residue can be recycled There is an advantage that can be.

Examples of the apparatus for dehydrating and drying the moisture of the sludge include a drying apparatus for supplying steam to the cylinder into which the sludge is introduced to dry the dehydrated sludge by dehydrating the sludge, And a centrifugal separator for removing moisture by centrifugal force by rotating the sludge at a high speed.

In particular, when it is assumed that the drying apparatus for drying steam by sucking moisture from the sludge by supplying steam is to dry the same amount of sludge, it is possible to shorten the drying time required for drying than other drying apparatuses, In most sludge treatment processes, there is used a drying device which supplies steam to dehydrate the sludge by dehydrating the sludge.

A drying device for drying food sludge is disclosed in Japanese Patent Application No. 10-1314519 (registration date: 2013.09.27. 2013) as a drying device technique in which steam is supplied and dried by deodorizing the moisture of the sludge. In the drying apparatus, steam is supplied to the periphery of a cylindrical drying drum and steam is supplied to the inside of a stirrer provided inside the drying drum to stir the sludge, thereby drying the sludge by dehydrating moisture from the sludge .

However, since the conventional art does not have a structure for discharging the steam supplied to the inside of the agitator, when the sludge is continuously dried in a state in which the supplied steam is not discharged, the drying effect by the steam heat becomes insignificant There is a limit in that the drying efficiency of the sludge by steam heat can not be constantly displayed.
