Hereinafter, an ultra-high temperature drying apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a schematic sectional configuration of an ultra-high temperature drying apparatus according to the present invention, FIG. 2 is a view for explaining a main constitution of an ultra-high temperature drying apparatus according to the present invention, Quot; and FIG. 4 is a view schematically showing a cross-sectional shape of the hot air supply pipe at the point "B" in FIG.

As shown in these drawings, the ultra-high temperature drying apparatus according to the present invention includes a burner 10, a drying object input port 50, a primary drying unit 20, a secondary drying unit 30, a discharge unit 40 A hot air supply pipe 60, a blowing motor 70, a blowing pipe 72, a blower motor driving circuit 84, a key input unit 80, a control circuit unit 82 and a display unit 86.

The burner 10 is configured to generate and output an ultra-high temperature hot air of 1,200 ° C to 5,000 ° C at high speed.

The drying object input port 50 is a structure for inputting a drying object having a high water content, such as, for example, sewage sludge collected in a sewer or food waste collected in a general household or a food factory.

The primary drying unit 20 is configured to primarily dry by the hot air at high temperature and high speed generated by the burner 10 while moving the drying object introduced through the drying object input port 50.

The secondary drying unit 30 is configured to perform secondary drying while moving the dried object to be dried in the primary drying unit 20.

The discharge unit 40 is configured to discharge an object to be dried having a water content of about 4 to 5%, which has passed through the secondary drying unit 30. In the ultra-high temperature drying apparatus of the present invention, the water content of the sewage sludge is dried to about 4 to 5%, and it is confirmed that the self-heating amount of the dried sewage sludge has 4,500 to 4,800 calories. Therefore, the ultra-high temperature drying apparatus of the present invention can recycle sewage sludge to be used as fuel.

The hot air supply pipe 60 is disposed between the burner 10 and the primary drying unit 20 and transfers the hot air of 1,200 ° C. to 5,000 ° C. generated in the burner 10 to the primary drying unit 20. . The hot air supply pipe 60 includes an inner pipe 64 communicated between the burner 10 and the primary drying unit 20 and a plurality of inner pipes 64 arranged to surround the inner pipe 64, And an outer tube 62 which is blocked by the blocking portion 66 and is opened to the primary drying portion 20 side.

The air blowing motor 70 sucks outside air and supplies outside air to the air supply space 68 between the inner tube 64 and the outer tube 62 constituting the hot air supply tube 60 through the air blowing pipe 72 .

The blowing pipe 72 is configured to supply the blowing air generated from the blowing motor 70 to the air supply space 68 between the inner pipe 64 and the outer pipe 62 of the hot air supply pipe 60.

The blowing motor driving circuit 84 drives the blowing motor 70 under the control of the control circuit 82 to adjust the blowing amount generated and output by the blowing motor 70.

The control circuit unit 82 controls the display unit 86 when the moisture content of the object to be dried is inputted from the key input unit 80 and registered. And controls the blowing motor driving circuit unit 84 to drive the blowing motor 70 in accordance with the moisture content of the object to be dried.

For example, when the moisture content of the object to be dried is 75% or less, the blowing motor 70 is driven at a low speed so as to maximize the amount of air blown into the air supply space 68 of the hot air supply pipe 60, To 80%, the blowing motor 70 is driven at a high speed so that the amount of air blown into the air supply space 68 of the hot air supply pipe 60 is large, and when the moisture content of the object to be dried is 80% to 85% The air blowing motor 70 is driven at a medium speed so that the amount of blowing air supplied to the blowing air supply space 68 of the hot air supply pipe 60 is medium and when the moisture content of the object to be dried is 85% 70 are driven at a low speed so that the air blowing amount supplied to the air supply space 68 of the hot air supply pipe 60 is small and when the water content of the object to be dried is 95% The hot air supply pipe 60, It supplied to the supply air flow space 68, so that blowing air volume can be the smallest amount is supplied. This is because when the water content of the object to be dried is low, the cold air is supplied to the primary drying unit 20 through the hot air supply pipe 60 by the blowing motor 70 so that the drying object is dried and dried And when the moisture content of the object to be dried is high, the cold air is supplied to the primary drying unit 20 through the hot air supply pipe 60 by the blowing motor 70 in a small amount, Drying can be prevented.

The blowing air supplied to the air supply space 68 of the hot air supply pipe 60 absorbs the heat of the inner pipe 64 and the outer pipe 62 of the hot air supply pipe 60 and flows into the primary drying furnace 20 Thereby contributing to the drying of the object to be dried. Therefore, the drying efficiency of the drying object can be improved while preventing the durability problems such as the curving phenomenon due to the overheating of the inner pipe 64 and the outer pipe 62 of the hot air supply pipe 60. In addition, the front end of the primary drying unit 20 adjacent to the hot air supply pipe 60 is also cooled, thereby improving the durability of the front end of the primary drying unit.

Also, by controlling the amount of air blown into the air supply space 68 of the hot air supply pipe 60 according to the water content of the object to be dried, efficient drying performance of the object to be dried can be achieved.

The present invention is not limited to the above-described specific embodiments, and various modifications and changes may be made without departing from the gist of the present invention. It will be obvious that such modifications and variations are included in the appended claims.
