The rotary culler 2 is provided with a charging port 21 capable of being opened and closed at one side thereof and a discharging port 22 formed at the other side thereof and a screw 23 is formed on the inner peripheral edge thereof, And the polymer compound is interlocked with the screw 23 in the direction of the discharge port 22 so that pyrolysis is performed.

In the present invention, the rotary culler 2 rotates the rotary culler 2 itself by a motor as shown in FIG. 2, so that it can heat a large area and evenly heat the heat, thereby improving the pyrolysis efficiency.

The heating method of the rotary culler 2 is known in the art, so that detailed description thereof will be omitted.

A sludge outlet 24 is formed in the rotary culler 2 in the direction of the inlet 21 so that the sludge outlet 24 is connected to the rotary culler 2 in the reverse direction So that the sludge is discharged through the screw 23 to the sludge discharge port 24.

In the process of pyrolyzing the rotary cullet 2, the sludge including tar and the like is immersed in the rotary culler 2. The present invention is characterized in that the rotary culler 2 rotates in the direction opposite to the direction of rotation in the pyrolysis process The sludge immersed in the rotary culler 2 is guided in the direction opposite to the discharge port 22 due to the action of the screw 23 and discharged to the sludge discharge port 24, thereby simplifying the separate cleaning process.

The exhaust holes 262 are formed in the exhaust surface 261,

The discharge pipe 26 is internally fixed within the discharge port 22 so that the rotary culvert 2 rotates about the discharge pipe 26. Particularly, the discharge pipe 26 has one end connected to the rotary Coulomb The reason for this construction is that as shown in FIG. 4, foreign matter deposited on the inner circumference of the rotary cullet 2 flows in the direction of the discharge port 22 due to the action of the screw 23, The discharge pipe 26 is formed to protrude from the inside of the rotary culler 2 to prevent the flowing sludge S from flowing into the discharge hole 262 of the discharge pipe 26, To control the generation of load and to produce refined oil of good quality.

And also controls the clogging of the discharge pipe 26 itself by the sludge. This is because, in the case of gas G by pyrolysis, a vortex is formed by the discharge pipe 26 protruded when flowing along the inner periphery of the rotary culler 2, so that foreign substances mixed in the gas G are separated, So that only the gas flows through the discharge pipe 26 to the rear end.

Preferably, the discharge hole 262 is formed in the shape of a long hole so that foreign matter mixed in the gas is filtered without hindering the flow of the fluid.

As shown in FIG. 5, the present invention provides an embodiment for controlling the inflow of the sludge S into the discharge pipe 26 and further enhancing the removal efficiency of the foreign substances from the gas.

6 can be attached to and detached from the discharge pipe 26 and has a second closed surface 271 at its end and a plurality of second exhaust holes 272 formed at the second closed surface 271, The second discharge pipe 27 is configured to be mounted on the discharge pipe 26 so that the second face 271 and the discharge face 261 of the discharge pipe are spaced apart from each other to form a settling space 28. [

The second discharge pipe 27 is mounted on the discharge pipe 26 and the second closing face 271 of the second discharge pipe 27 and the closing face 261 of the discharge pipe 26 are spaced from each other, .

The inner diameter of the second discharge pipe 27 is set to be the same as the outer diameter of the discharge pipe 26 so that the second discharge pipe 27 is fitted to the discharge pipe 26, The second discharge pipe 27 is detached from the discharge pipe 26 to clean the deposited foreign matter.

The operating relationship of the present embodiment is that the gas introduced through the second discharge hole 272 of the second discharge pipe 27 collides against the closing face 261 of the discharge pipe 26, So that the separated gas is discharged to the rear end through the discharge hole 262 of the discharge pipe 26. [

The discharge hole 262 and the second discharge hole 272 are formed to have a long hole shape in one direction to further increase the deposition efficiency in the sedimentation space 28. The discharge hole 262 and the second discharge hole 272 are alternately And the second discharge pipe (27) is assembled to the discharge pipe (26) so as to be positioned orthogonally to the second discharge pipe (27).

That is, the gas introduced into the second exhaust hole 272 by the mutually orthogonal long hole 262 and the second exhaust hole 272 collides with the closed surface 261 in a larger area and is mixed with the gas So that the separation efficiency of the foreign matter can be improved.

The gas discharged from the rotary culler 2 mentioned above flows into the separator 3 at the downstream stage. The separator 3 separates the discharged gas into a heavy oil gas and a light oil gas. The separating device 3 has a variety of known technologies. For example, the discharge port is provided at the upper part and the lower part so that the heavy oil having a high specific gravity is discharged to the discharge port at the lower part.
