Here, the condensation process is reinforced by the same distillation system as the petrochemical process in order to obtain good quality pyrolysis oil.

The most important process in pyrolysis is the calking phenomenon when the waste synthetic resin is pyrolyzed. The coking phenomenon occurs when the pyrolyzed hydrocarbon comes into contact with the inner wall of the reactor containing the heated iron or nickel to separate the hydrogen and the carbon is separated from the inner wall of the pyrolysis tank If the coating is cured by coating, the thickness of the caulking is continuously increased, which causes the cracking tank to rupture. Therefore, most of the pyrolysis reactors have a mechanical structure capable of suppressing or controlling the caulking so that the generation of caulking does not occur.

Reference numeral 90 denotes a combustion burner, and reference numeral 91 denotes a combustible gas combustion burner.

The extraction of pyrolysis oil from the waste synthetic resin by the apparatus of the present invention will be described in more detail as follows.

First, the cooling water is supplied to the secondary cooling tank 40 at a predetermined level below the non-condensing gas backflow prevention discharge pipe 41 before the heat is applied to the pyrolysis heating tank 10, To cool the water flowing into the cooling pipe 81.
Then, the inlet 11 at the top of the pyrolysis heating tank 10 is opened and a certain amount of lead (Pb) used as a metal catalyst is supplied. The amount of lead (Pb) used as the metal catalyst varies depending on the size of the pyrolysis heating tank 10.

When the operation ready state is completed, the charging port 11 at the upper end of the pyrolysis heating tank 10 is opened and the waste synthetic resin is charged with a heat quantity, and then the charging port 11 is closed with the lid. Then, the combustion burner 90 at the bottom is ignited to start preheating the pyrolysis heating tank 10.
When the thermal power through the combustion burner 90 is continuously heated as described above, the lead (Pb) used as the metal catalyst introduced into the pyrolysis heating tank 10 reaches 330 ° C The lead is melted and changed into a liquid state and is settled on the inner bottom surface of the pyrolysis heating tank 10.
When the pyrolysis heating tank 10 is heated in this state and the waste synthetic resin is pyrolyzed in a liquid state, the speed reducer 6 installed at the upper end of the pyrolysis heating tank 10 is operated to rotate the small chain gear 4, Is rotated through rotation of the rotary vane 1 fixed to the lower end while rotating the rotary shaft 2 by rotating the gear 3 which is an alternative to the upper end of the rotary shaft 2 installed at the center of the pyrolysis heating tank 10 The waste synthetic resin is stirred at the same time as the metal catalyst lead and the waste synthetic resin is dissolved in the liquid state. The waste synthetic resin starts to change from a solid state to a liquid state while pyrolyzed by indirect heat transmitted from the thermal decomposition heating tank 10.

The pyrolysis heating tank 10 is heated and the water cooler 80 and the pumping water pump 71 are operated to start circulating the cooling water. The cooling water stored in the secondary cooling tank 40 flows into the primary product supply pipe 72 while the impurities are filtered through the filter device 70 and the cooling pipe 81 And then starts to supply the cooling water to the pipe of the cooling exhaust pipe 30 after passing through the secondary product supply pipe 73.
At this time, the supplied cooling water is supplied to the cooling tank water supply pipe 74 at the upper end of the primary cooling tank 20 at the same time.
As the pyrolysis heating tank 10 is continuously heated as described above and the internal temperature reaches 300 ° C. to 450 ° C., the waste synthetic resin injected into the pyrolysis heating tank 10 is burned by the indirect heat. As a result, combustible gas is generated in the pyrolysis heating tank 10 do.

The combustible gas thus generated flows into the primary cooling tank 20 through the communication pipe 12 at the upper end of the pyrolysis heating tank 10. At this time, if the gas injected through the nozzles provided in the first stage is cooled through the cooling tank water supply pipe 74 installed at the upper end, the temperature of the combustible gas is lowered and the gas is lowered together with the cooling water .

When the pyrolysis heating tank 10 is heated to thermally decompose the waste synthetic resin into a liquid state, the speed reducer 6 installed at the upper outer side of the pyrolysis heating tank 10 is operated for complete combustion to rotate the small chain gear 4 The rotary 3 is rotated through the chain 5 as a substitute for the upper end of the rotary shaft 2 provided at the center of the pyrolysis heating tank 10 so as to rotate the rotary blade 1 fixed to the lower end of the rotary shaft 2, , It is possible to agitate the waste synthetic resin liquid in a liquid state and the waste synthetic resin which is being dissolved in a semi-liquid state to uniformly pyrolyze.

As described above, the combustible gas flowing into the primary cooling tank 20 flows in multiple stages to the cooling water discharge pipe 30 at the lower stage together with the cooling water sprayed from the upper end of the cooling water supply pipe 74, and lowers the temperature of the combustible gas .
The combustible gas passing through the multistage cooling water discharge pipe 30 first flows into the primary gas inflow pipe 31 installed at the center of the primary cooling tank 20 and at the same time flows into the primary gas inflow pipe 31 The cooling water is injected from the injection port (21) of the car spiral, and the temperature is dropped again.

As described above, the combustible gas passing through the primary gas inflow pipe 31 is horizontally coupled to the primary gas inflow pipe 31, and the secondary inflow injection port 22 for spraying the cooling water on the vertical line is fixed, The gas is introduced into the pipe 32 and cooled again by the cooling water injected from the secondary helical injection port 22 to be sent to the tertiary gas inflow pipe 33. The combustible gas flowing into the tertiary gas inflow pipe 33 The temperature of the combustible gas is again lowered through the third helical injection port 23 which is vertically coupled to the secondary gas inlet pipe 32 and injects the cooling water on the horizontal line.

The combustible gas that has passed through the third gas inflow pipe 33 flows into the fourth gas inflow pipe 34. The combustible gas flows into the fourth gas inflow pipe 34 and flows into the third gas inflow pipe 33, The cooling water is injected again through the fourth helical injection port 24 which injects the cooling water on a vertical line and the combustible gas flows into the fifth gas inlet pipe 35 and the fifth gas inlet pipe 35, The cooling water is injected again through the fifth spiral jet opening 25 so as to inject the cooling water onto the horizontal line by vertically coupling the combustible gas to the fourth gas inflow pipe 34 at the same time as the combustible gas is introduced.

The reason why the cooling water is injected in multiple stages as described above is that in order to cool the combustible gas, the cooling water is brought into contact with the area of contact with the combustible gas within a maximum range to gradually condense the heat and to condense the pyrolysis gas. to be.

As described above, when the temperature of the combustible gas passing through the fifth gas inlet pipe 35 is cooled, the oil components contained in the combustible gas are mostly changed into pyrolysis passages by the thermal reaction and flow into the secondary cooling tank 40.

In this case, the cooling water and the changed thermal cracking oil passing through the cooling water discharge pipe 30 of the multi-stage process are collected in the secondary cooling tank 40. In this case, the cooling water having a heavy specific gravity falls downward. Condensed gas backflow preventing pipe 41 connected to the secondary cooling tank 40 and is accumulated in the storage tank 50 through the non-condensing gas backflow prevention discharge pipe 41. [

The residual uncompacted combustible gas, which has not undergone the pyrolysis flow path change, is discharged through the gas discharge pipe 42 installed at the upper part of the secondary cooling tank 40 and flows into the gas combustion chamber 60 through the gas combustion burner 91 And burns the gas completely.

The reason why the U-shaped bent portion 43 is formed in the uncompacted gas backflow preventive discharge pipe 41 provided on the side portion of the secondary cooling tank 40 as described above is that the pyrolysis oil collected in the secondary cooling tank 40 flows into the non- The residual pyrolysis oil gathered in the U-shaped bent portion 43 blocks the non-condensed gas backflow prevention discharge pipe 41 when the flow of the uncompensated gas 41 is lowered to the lower level and the flow into the storage tank 50 is stopped, So as to prevent backflow.

As described above, the cooling water collected in the secondary cooling tank 40 is heated by the temperature of the combustible gas while being moved through the primary cooling tank 20 and the cooling discharge pipe path 30 to maintain the hot water state, The remaining waste in the secondary cooling tank 40 is removed through the filter device 70 and then the cooling pipe 81 is passed through the primary product supply pipe 72 In the process of passing the water, the water cooler 80 at the upper part cools water in a hot water state so that it can be used as cooling water again and is sent to the secondary product supply pipe 73. Thus, a cycle of pyrolytic oil production process is completed, It is possible to extract pyrolysis oil by continuous process.

In the present invention as described above, in the thermal decomposition of the waste synthetic resin, heat is directly applied to the thermal decomposition heating tank 10 by the burning burner 90, and the waste synthetic resin in the lower part, which can maintain a high temperature, And the waste synthetic resin in the upper portion may cause coking due to a temperature difference between the lower end portion and the lower end portion. However, since the lead component liquefied by the high temperature is introduced into the thermal decomposition heating tank 10, The rotation of the rotary shaft 2 coupled to the gear 3 which is an alternative to the rotation of the gear 3 which is an alternate operation of the small chain gear 4 operated by the chain 5, 1) is rotated so that the liquefied lead is stirred and the waste synthetic resin is burned while being diluted with the liquefied lead, thereby preventing the caulking phenomenon in the pyrolysis heating tank 10.
The amount of the lead (Pb) used as the metal catalyst in the pyrolysis heating tank 10 varies depending on the size of the pyrolysis heating tank 10.
For example, the pyrolysis heating tank 10 is charged with about 1,500 kg of lead used as a metal catalyst in a size of about Ø1,800 mm × h 2,000 mm, and the pyrolysis heating tank 10 is heated to raise the temperature from 330 ° C. to 430 ° C. The lead (melting point: about 327 ° C.) in which lead used as a metal catalyst is melted and changed into a liquid phase is stored in a state of being changed into a liquid state on the inner bottom surface of the pyrolysis heating tank 10 because the specific gravity (11.34)
When the thermal decomposition heating tank 10 is continuously heated to decompose the waste synthetic resin into a liquid state, the speed reducer 6 installed at the upper end of the pyrolysis heating tank 10 is operated to rotate the small chain gear 4, The rotation of the rotary vane 1 fixed to the lower end while rotating the rotary shaft 2 is performed by rotating the gear 3 provided at the upper end of the rotary shaft 2 provided at the center of the pyrolysis heating tank 10 through the rotary shaft 5, The waste synthetic resin that is dissolved in the liquid state together with the metal catalyst lead in the state is stirred so that the waste synthetic resin is not solidified due to the unburned combustion, thereby preventing the caulking phenomenon in the thermal decomposition heating tank 10.
The above-mentioned caulking phenomenon does not cause 100% caulking phenomenon at the bottom of the pyrolysis heating tank 10 in which lead is melted, and occurs slightly at a wall surface of about 100 mm, but does not significantly affect gas generation .
The use of about 1,500 kg of lead in the pyrolysis heating tank 10 as described above indicates the weight according to the size of the pyrolysis heating tank 10 exemplified as an example. In stirring the lead in a liquid state, ) Is rotated while the lead is melted and locked about 20 mm in the liquid state and mixed with any waste synthetic resin such as polypropylene (PP), polyethylene (PE), polycarbonate (PC) And the pyrolysis oil can be extracted.
