荷も小さくなる。In conventional processing equipment, the step of separating granulated water from granulated water slurry is performed in one step. In contrast, in the present invention, relatively large-diameter granulated water is separated by a screw conveyor provided upstream of the granulated water tank, and then a filtration system that exerts the filtration ability discovered by the present inventors is placed in the downstream part. A cylindrical filter with a pore size of less than 0.5n separates particles suspended in the granulated water slurry, such as hair-like granulated water and small-diameter granulated water. By carrying out the separation process in two stages in this manner, each process is carried out efficiently, and the load on the screw conveyor or cylindrical filter is also reduced.

ため、毛状水砕。Furthermore, by selecting a cylindrical filter with a filtration pore size of less than 0.5 fi in relation to the slurry concentration, a water head difference is created between the inlet and outlet sides of the cylindrical filter, and this water head difference allows for water pulverization. Hair-like water particles, small-diameter water particles, etc. floating and suspended in the slurry are filtered under pressure. Therefore, hair-like hydration.
小径水砕等の分離が迅速に行われ、従来の装置にみられ

No extra energy is required, and the device itself has a simple configuration.

This water head difference becomes pressure, and the granulated slurry 2 is forced into the cylindrical filter FD and filtered, and the filtrated water is discharged from the outlet WG under its own weight. In this way, the cylindrical filter FD
When passing through the granulated water slurry 2, hair-like granules, small-diameter granules, etc. floating and suspended in the granulated water slurry 2 are captured by the cylindrical filter FD.

is a double pipe, and is connected to a water supply source or conduit 13 via an appropriate pressure and flow rate adjustment valve (not shown) through the inner pipe IP. This water injection nozzle-N may be one having a slit-shaped opening provided along the width direction of the cylindrical filter FD, or one consisting of a plurality of nozzle groups provided along the width direction. Also, in place of this water injection nozzle-N, a nozzle that injects compressed air may be employed. Alternatively, it is of course possible to remove the accumulated hair-like water particles, small-diameter water particles, etc. by providing a mechanical scraper so as to face the wire mesh of the cylindrical filter FD.

The water is cooled while flowing down the cooling tower 10 and stored in the cold water tank 11. The treated water in the cold water tank 11 is returned to the blowing apparatus 1 via a pipe line 13 by a circulation pump 12.

ター面のみを使用した例である。The hair-like water particles, small-diameter water particles, etc. that are crimped onto the cylindrical filter FD are below the level of the rotation axis R3, that is, the cylindrical filter F
When the surface D faces downward, it may be easy to separate from the filter surface again depending on the size of the diameter of the cylinder and the water pressure from the depth of the granulation tank 3. As a result, there is a possibility that the particles may be deposited below the cylindrical filter FD and hinder the operation of the cylindrical filter FD and the flow of the granulated water slurry 2. Therefore, in order to prevent hair-like water particles, small-diameter water particles, etc. from adhering to the filter surface facing downward of the cylindrical filter FD, the center of rotation of the cylindrical filter FD is lowered in relation to the flow of the granulated water slur IJ-2. This is an example in which only the upwardly oriented filter surface of the type filter FD is used.

れる。As explained above, in the granulated water production apparatus of the present invention, by sequentially providing a screw conveyor and a cylindrical filter in the upstream and downstream parts of the granulated water tank, the water suspended and Qi in the granulated water slurry is The crushed pieces are taken out separately according to their particle size. That is, medium and large particle diameter granules are discharged by a screw conveyor, and hair-like granules, small-diameter granules, etc. are separated by a cylindrical filter using the water pressure of the granule slurry.
It is being discharged. Therefore, there is no need to install not only a dewatering tank but also a large-scale sedimentation tank or sedimentation tank, and the equipment becomes small and simple, and equipment costs and maintenance costs can be significantly reduced. The treated water after the granulated water has been separated in this way can be returned to the blowing device and can be fully reused. Moreover, the productivity of granulated water is dramatically improved, and the processing cost of granulated water is significantly reduced, which brings about many effects.
