The pyrolysis furnace 100 is a pyrolysis furnace used to produce waste plastic pyrolysis oil, and may be formed in the form of a tube with a hollow interior.

As shown in FIG. 2, the pyrolysis furnace 100 has a base portion 110 that is open at the top and has a U-shaped cross section, and a cover portion 120 that covers and seals the top of the base portion 110. may include.

This makes it easy to open the pyrolysis furnace 100, making maintenance easier, and makes it easy to install other devices such as the ultrasonic vibrator 200 and pressure valve.

The ultrasonic vibrator 200 includes an ultrasonic vibrator 210 and causes an ultrasonic cavitation phenomenon inside the thermal decomposition furnace 100.

The ultrasonic vibration unit 200 is a device that receives power and generates ultrasonic vibration. It is installed in the pyrolysis furnace 100 and transmits the generated ultrasonic vibration to the pyrolysis furnace 100.

The ultrasonic vibration generated from the ultrasonic vibrator 200 is transmitted to the material (plastic waste, etc.) for thermal decomposition inside the pyrolysis furnace 100, generating cavitation due to vibration, and the cavitation causes the pyrolyzed material (molten It promotes decomposition by creating an environment in which the polymer links of plastic waste, etc. are easily broken.

The cooling unit 300 cools the ultrasonic vibration unit 200.

Since the cooling unit 300 can quickly absorb the heat transferred from the pyrolysis furnace 100 to the ultrasonic vibrating unit 200 and lower the temperature of the ultrasonic vibrating unit 200, the ultrasonic vibrating unit 200 can be used even in a high temperature environment. It is possible to provide ultrasonic vibration for a long time while preventing damage due to heat in the eastern part 200.

As shown in FIG. 2, the pyrolysis furnace 100 of the ultrasonic pyrolysis device according to an embodiment of the present invention may be formed with a through hole into which a part of the ultrasonic vibration unit 200 is inserted.

This is to allow a part of the ultrasonic vibrating unit 200 to be inserted into the interior of the pyrolysis furnace 100.

As shown in FIG. 2, one side of the ultrasonic vibration unit 200 of the ultrasonic pyrolysis device according to an embodiment of the present invention is exposed to the outside of the pyrolysis furnace 100, and the other side is exposed to the interior space of the pyrolysis furnace 100. It is provided to be accommodated in, and the ultrasonic vibrator 210 may be provided to be exposed to the outside of the pyrolysis furnace 100.

In order to increase the effectiveness of ultrasonic decomposition, which breaks polymer links by ultrasonic waves, it is best to transmit ultrasonic waves directly to pyrolyzed materials (molten plastic waste, etc.).

The interior of the thermal decomposition furnace 100 is maintained at a high temperature for thermal decomposition, but the ultrasonic vibrating unit 200 may not function properly or be damaged at high temperatures.

Therefore, the ultrasonic vibrator 210 part of the ultrasonic vibrator 200 is exposed to the outside of the thermal decomposition furnace 100, and the ultrasonic transmission part (horn part, vibration guide part 220) of the ultrasonic vibrator 200 ) is preferably accommodated in the internal space of the pyrolysis furnace 100.

In Figure 2, only one ultrasonic vibrating unit 200 is shown on the right, but the present invention is not limited to this, and more ultrasonic vibrating units 200 are provided on both left and right sides around the rotating shaft unit 130. ) can of course be installed and used in various ways.

As shown in Figure 2, the ultrasonic vibration unit 200 of the ultrasonic pyrolysis device according to an embodiment of the present invention includes a vibration guide unit 220 that transmits ultrasonic vibration of the ultrasonic vibrator 210, One side of the vibration guide part 220 is in contact with the ultrasonic vibrator 210, and the other side of the vibration guide part 220 is provided to be accommodated in the internal space of the pyrolysis furnace 100, and the vibration guide part 220 is It may be characterized in that the cross-sectional area of some of the cross-sections in the other direction is smaller than the end cross-section in one direction.

The ultrasonic vibrating unit 200 may not function properly or may be damaged at high temperatures.

Therefore, it is desirable to minimize heat transfer to the ultrasonic vibrator 210 portion of the ultrasonic vibrator 200, and for this purpose, the vibration guide portion 220 is provided. It is preferable that the partial or total cross-sectional area on the side of the pyrolysis furnace 100 is smaller than the partial cross-section in contact with the ultrasonic vibrator 210.

In the drawing, the shape of the vibration guide unit 220 is shown to have a cross-section that becomes smaller and then becomes constant as it moves toward the pyrolysis furnace 100. However, the present invention is not limited to this, and the part inserted into the through hole or the through hole is Various practices such as making the cross-section of the part adjacent to the part inserted into the ball smaller than the cross-section of the part in contact with the ultrasonic vibrator 210, and then gradually widening the cross-section of the part in direct contact with the pyrolyzed material (molten plastic waste, etc.) Of course, it is possible.

As shown in FIG. 2, the ultrasonic vibration unit 200 of the ultrasonic pyrolysis device according to an embodiment of the present invention has a portion having a smaller cross-sectional area than the end cross-section in one direction of the vibration guide unit 220, which is in the pyrolysis furnace 100. ) It may be characterized as being inserted and fixed into the through hole.

This is to minimize contact between the ultrasonic vibrator 200 and the outer wall of the pyrolysis furnace 100 and minimize heat transfer through the outer wall of the pyrolysis furnace 100.

As shown in FIG. 2, the ultrasonic vibration unit 200 of the ultrasonic pyrolysis device according to an embodiment of the present invention may be provided at the top of the pyrolysis furnace 100.

The ultrasonic vibrator 200 is provided at the upper part of the pyrolysis furnace 100 because there is pyrolyzed material (molten plastic waste, etc.) in the lower part of the pyrolysis furnace 100. This is to minimize the heat transferred from (waste, etc.) to the ultrasonic vibrator 210 of the ultrasonic vibrator 200.

Since pyrolyzed materials (molten plastic waste, etc.) accumulate in the lower part of the pyrolysis furnace 100 due to gravity, it is preferable that the ultrasonic vibrator 210 portion of the ultrasonic vibrator 200 is provided at the top.

As shown in FIG. 3, the pyrolysis furnace 100 of the ultrasonic pyrolysis device according to an embodiment of the present invention includes a rotation shaft portion 130 rotatably provided inside the pyrolysis furnace 100 and the rotation shaft portion ( 130), rotates with the rotation shaft portion 130, and may include a screw portion 140 formed in a screw shape.

The pyrolysis furnace 100 causes pyrolysis when the material to be pyrolyzed is input into the inlet 180, and the material that has been pyrolyzed to the desired extent must be discharged through the outlet 190.

The screw unit 140 is for moving a material for pyrolysis (plastic waste, etc.) or a pyrolyzed material (molten plastic waste, etc.) toward the discharge port 190, and the rotating shaft portion 130 is the screw portion. It is configured to rotate (140).

As shown in FIG. 3, the pyrolysis furnace 100 of the ultrasonic pyrolysis device according to an embodiment of the present invention is configured to prevent the screw part 140 from contacting the ultrasonic vibration unit 200 while rotating. It may be characterized in that a section in which the screw portion 140 is broken is formed in a section where the ultrasonic vibrating unit 200 is provided.

When the screw part 140 formed in the shape of a screw is formed in the entire section of the rotation shaft part 130, the screw part 140 rotates and collides with the ultrasonic vibration unit 200, causing the ultrasonic vibration unit 200 to It can be damaged.

Therefore, it is desirable to prevent the screw part 140 formed in a screw shape from contacting the ultrasonic vibration unit 200.

To this end, a broken section can be formed so that no part comes into contact with the ultrasonic vibrating unit 200 even when the wing portion of the screw unit 140 rotates.

As shown in FIG. 3, the pyrolysis furnace 100 of the ultrasonic pyrolysis device according to an embodiment of the present invention is formed such that the direction of the blades of the screw portion 140 is opposite to that of the outlet 190. It can be characterized as:

If the outlet 190 is installed at the very end of the pyrolysis furnace 100, there will be no problem with the direction of the blades of the screw part 140, but the outlet 190 is a certain distance from the end of the pyrolysis furnace 100. When placed spaced apart, there is a problem that the pyrolyzed material that has passed the outlet 190 continues to move in a direction away from the outlet 190.

To solve this problem, the screw part 140 is formed so that the direction of the blades is opposite to the outlet 190, so that the pyrolyzed material that has passed through the outlet 190 moves back toward the outlet 190. It can be made to be discharged.

In FIG. 3, it can be seen that the directions of the wing provided on the left and the right side of the outlet 190 are opposite to each other, and that the directions of the wings are opposite to each other mean that the rotation shaft portion 130 This means that the direction in which the materials inside the pyrolysis furnace 100 are moved by rotation is reversed.

As shown in Figure 3, the rotating shaft portion 130 of the ultrasonic pyrolysis device according to an embodiment of the present invention is formed in the form of a conduit with a hollow center centered around the rotating shaft, and the fluid heated by the external furnace 900 It may be characterized in that the interior is heated by the thermal decomposition 100 while passing through the rotating shaft portion 130 in the form of a conduit.

In order to heat the inside of the pyrolysis furnace 100, a heating device may be attached to the outside. However, in this case, since heat loss increases, it is preferable to place a heat source near the inside of the pyrolysis furnace 100. do.

By using a heated fluid as a heat source and allowing the heated fluid to pass through the rotating shaft portion 130, the interior can be heated by the thermal decomposition 100 more efficiently.

The external furnace 900 can maintain the temperature inside the pyrolysis furnace 100 at 450 degrees by sending fluid of about 700 to 1000 degrees.

As shown in FIGS. 4 and 5, a plurality of the pyrolysis furnace 100 of the ultrasonic pyrolysis device according to an embodiment of the present invention may be configured to be arranged in multiple stages in the vertical direction.

The purpose of arranging them in multiple stages is to reduce the site area for installing pyrolysis pipes for miniaturization and to enable installation even in narrow sites.

The multi-stage arrangement in the vertical direction is to enable easier discharge and input by using the force of gravity to move the material discharged from the front outlet to the rear inlet.

4 to 5, the material introduced into the inlet side of the first (top side) pyrolysis furnace 100 goes through a process of removing moisture at a temperature of about 150 degrees and is transferred to the right side toward the outlet. is moved to

The material introduced into the second pyrolysis furnace 100 through the outlet of the first pyrolysis furnace 100 undergoes primary pyrolysis and chlorine removal at a temperature of about 250 degrees and is moved to the left.

The material introduced into the third pyrolysis furnace 100 undergoes secondary pyrolysis and primary ultrasonic pyrolysis at a temperature of about 350 degrees and is moved to the right.

The material introduced into the fourth pyrolysis furnace 100 (lowest side) undergoes third pyrolysis and second ultrasonic pyrolysis processes at a temperature of about 450 degrees and is moved to the left.

In other words, the pyrolysis furnace 100 formed in multiple stages can be operated with the temperature increasing as it moves to the next stage.

At this time, since the rotating shaft 130 is formed in the form of a conduit, the pipe can be communicated so that the fluid heated by the external furnace 900 passes through the inside of the conduit rotating shaft portion 130.

In the embodiments of FIGS. 4 and 5, a zigzag pipe connection is used as an example to clearly show the regularity to aid understanding. However, the present invention is not limited to this, and of course, various implementations are possible.

In addition, Figure 4 shows a chamber in which heated fluid can remain between stages, but of course, it is also possible to omit the chamber as shown in Figure 5.

Additionally, the pyrolysis furnace 100 can be arranged to form a certain angle of inclination (in FIG. 4, a 5 degree inclination) in the direction in which the internal materials are to be moved. This is to use the power of gravity in addition to the power of the screw.

In addition, it is desirable to use a cool bearing as the bearing connected to the rotating shaft 130. This is to facilitate rotation because the temperature of the rotating shaft itself is high.

As shown in FIG. 6, the cooling unit 300 of the ultrasonic pyrolysis device according to an embodiment of the present invention includes a first Peltier element unit 310 with one surface in contact with the ultrasonic vibrating unit 200, and the first It may include a first refrigerant circulation unit 320 that is in contact with the other surface of the Peltier element unit 310 and circulates refrigerant to cool the heat of the first Peltier element unit 310.

In order to lower the temperature of the ultrasonic vibrating unit 200, a refrigerant can be used, but in the present invention, the first Peltier element unit 310 is interposed between the ultrasonic vibrating unit 200 and the first refrigerant circulation unit 320. Equipped with this, cooling efficiency is further improved, and the electrical energy produced from the first Peltier element unit 310 can be recycled.

As shown in FIG. 7, the cooling unit 300 of the ultrasonic pyrolysis device according to an embodiment of the present invention includes a second Peltier element unit 330 with one surface in contact with the first refrigerant circulation unit 320, and the It may include a second refrigerant circulation unit 340 that is in contact with the other surface of the second Peltier element unit 330 and circulates refrigerant to cool the heat of the second Peltier element unit 330.

In other words, cooling efficiency can be further improved through multi-cooling consisting of multiple Peltier element units (310, 330) and refrigerant circulation units (320, 340).
