Pyrolysis treatment device with multi-stage multi-row structure and continuous waste synthetic resin pyrolysis treatment facility including the same

The present invention relates to a continuous waste synthetic resin pyrolysis treatment facility including a pyrolysis treatment device with a multi-stage multi-row structure. More specifically, in transferring and supplying waste synthetic resin to a pyrolysis transfer path, inputting and stirring the waste synthetic resin. , the entire process of compression and supply is carried out automatically and continuously, and transfer screw conveyors for pyrolysis are arranged in multiple stages and rows within one pyrolysis firebox, thereby maximizing efficiency by pyrolyzing a large amount of waste synthetic resin. It relates to a continuous waste synthetic resin pyrolysis treatment facility including a pyrolysis treatment device with a thermal structure.

Products made of synthetic resin, such as tires, vinyl, and plastic, which are widely used in various industrial fields and daily life, are recycled after use, and most are classified as waste and are landfilled or incinerated. These synthetic resin wastes are considerably larger in volume compared to their weight, so not only are landfill costs greater than regular waste, but they do not rot even when landfilled, so they are considered a social nuisance.

Recently, as a way to recycle synthetic resin waste without incinerating or landfilling it, research and development of emulsification methods and devices that can obtain useful oil by pyrolyzing synthetic resin waste has been actively conducted.

Conventionally, waste synthetic resin had to be added manually, so each time the material was added, the pyrolysis treatment device was stopped and a certain period of time passed before the material was added. This caused not only the inconvenience caused by adding the material, but also extremely low work efficiency. Because there are many problems, such as a significant decrease in productivity, there is a need to develop technology that can continuously operate the device and automatically input materials.

Accordingly, in the current pyrolysis treatment facility, a method of sequentially pyrolyzing waste through a plurality of transfer screws has been proposed. However, this pyrolysis device cannot increase the temperature at each stage, so the firebox temperature must be increased by increasing the supply heat source gas, so it has a large capacity. A burner was required, and there was a problem of clogging of the oil vapor duct and a large amount of tar being generated from the produced oil.

FIG. 2 is a diagram showing the configuration of the multi-stage pyrolysis transfer screw conveyor 140 shown in FIG. 1.
FIG. 3 is a diagram showing the overall configuration of a continuous waste synthetic resin pyrolysis treatment facility 200 including a pyrolysis treatment device using the multi-stage multi-row structure shown in FIG. 1.

Below, preferred embodiments are presented to aid understanding of the present invention. However, the following examples are provided only to make the present invention easier to understand, and the content of the present invention is not limited by the examples.

Figure 1 is a front view and a side view of a pyrolysis treatment device 100 with a multi-stage multi-row structure according to an embodiment of the present invention, and Figure 2 shows the configuration of the multi-stage pyrolysis transfer screw conveyor 140 shown in Figure 1. It is a drawing.

Looking at Figures 1 and 2, the pyrolysis treatment apparatus 100 with a multi-stage multi-column structure according to an embodiment of the present invention largely includes a pyrolysis reactor body 110, a first gas burner 120, and a plurality of second gases. It may be configured to include a burner 130 and a pair of multi-stage pyrolysis transfer screw conveyors 140.

First, the pyrolysis reactor body 110 is formed in a box shape, and inside it accommodates a first gas burner 120, a plurality of second gas burners 130, and a pair of multi-stage pyrolysis transfer screw conveyors 140, which will be described later. do. The pyrolysis reactor body 110 may be formed to have a width of 3.8 m.

Among the inner surfaces of the pyrolysis reactor main body 110, first gas burners 120 are provided on the weak side corresponding to the longitudinal direction, and each first gas burner 120 is angle adjustable at a 45 degree angle in the vertical direction. Since it has a possible universal joint structure, the internal temperature, flame state, and Depending on the temperature distribution of the gas discharge duct, the angle can be adjusted to maintain the required temperature. In particular, although not shown in the present invention, the internal temperature of the first to fourth pyrolysis transfer screw conveyors 141, 142, 143, and 144, which will be described later, is automatically measured, and as a result of the measurement, the internal temperature is not maintained normally and the cooling is lowered. In this state, the angle of the first gas burner 120 may be changed to discharge flame toward the corresponding pyrolysis transfer screw conveyor. In addition, as a result of the measurement, in an overheated state where the internal temperature is not maintained normally and becomes excessively high, the angle of the first gas burner 120 may be changed to discharge flame to avoid the corresponding pyrolysis transfer screw conveyor.

In particular, in the case of the fourth pyrolysis transfer screw conveyor 144 located at the bottom, the Char, which is a residue after pyrolysis, must be cooled and discharged to the outside, so the discharge temperature must be lowered to prevent the risk of fire. Therefore, in this case, the angle of the first gas burner 120 may be adjusted so as not to directly heat the fourth pyrolysis transfer screw conveyor 144.

A plurality of second gas burners 130 are arranged at regular intervals on the inner surface of the pyrolysis reactor main body 110, especially on both sides corresponding to the width direction, and, like the first gas burner 120, are angled at a 45 degree angle in the vertical direction. It has an adjustable universal joint structure. Therefore, the angle can be adjusted to maintain the necessary temperature according to the internal temperature and flame state of the first to fourth pyrolysis transfer screw conveyors (141, 142, 143, 144) and the temperature distribution of the gas discharge duct. At least 6 second gas burners 130 are disposed at regular intervals on one inner side of the pyrolysis reactor main body 110 and 12 or more are on both sides to perform heating.

These plurality of second gas burners 130, like the first gas burner 120, automatically measure the internal temperature of the first to fourth pyrolysis transfer screw conveyors (141, 142, 143, and 144), and provide internal temperature as a result of the measurement. In a cooling state where the temperature is not maintained normally and is lowered, the angle of the plurality of second gas burners 130 may be changed to discharge flame toward the corresponding pyrolysis transfer screw conveyor. In addition, as a result of the measurement, in an overheated state where the internal temperature is not maintained normally and becomes excessively high, the angle of the plurality of second gas burners 130 may be changed to discharge flames avoiding the corresponding pyrolysis transfer screw conveyor.

In particular, in the case of the fourth pyrolysis transfer screw conveyor 144 located at the bottom, the Char, which is a residue after pyrolysis, must be cooled and discharged to the outside, so the discharge temperature must be lowered to prevent the risk of fire. Therefore, in this case, the angle of the plurality of second gas burners 130 may be adjusted so as not to directly heat the fourth pyrolysis transfer screw conveyor 144.

The multi-stage pyrolysis transfer screw conveyor 140 is arranged in a pair to face each other at a certain interval within the pyrolysis reactor body 110, and sequentially transfers the waste synthetic resin input from the waste synthetic resin input device to the first And it serves to generate oil vapor by heating the second gas burner (120, 130).

More specifically, the multi-stage pyrolysis transfer screw conveyor 140 is configured to include second to fourth pyrolysis transfer screw conveyors 142, 143, and 144, starting with the first pyrolysis transfer screw conveyor 141 located at the top. . Since the first to fourth pyrolysis transfer screw conveyors (141, 142, 143, 144) are formed in a zigzag shape, the injected waste synthetic resin is transferred in a zigzag shape to the first and second gas burners (120, 130). It is thermally decomposed by heating and produces oil vapor.

The first pyrolysis transfer screw conveyor 141 is located at the top inside the pyrolysis reactor main body 110, and transfers the waste synthetic resin input from the waste synthetic resin input device to one side (for example, from left to right) and simultaneously And the first pyrolysis treatment is performed by heating the second gas burners 120 and 130.

The second pyrolysis transfer screw conveyor 142 is connected to the transfer end portion at the lower side of the first pyrolysis transfer screw conveyor 141, and transfers the pyrolysis material transferred from the first pyrolysis transfer screw conveyor 141 to one side (for example, the right side). to the left, and at the same time, secondary pyrolysis treatment is performed by heating the first and second gas burners 120 and 130. Since the rotation direction of the second pyrolysis transfer screw conveyor 142 is opposite to the rotation direction of the first pyrolysis transfer screw conveyor 141, the pyrolyzate subjected to the secondary pyrolysis treatment is in the opposite direction to the pyrolyzate subjected to the primary pyrolysis treatment. is transported.

The third pyrolysis transfer screw conveyor 143 is connected to the transfer end portion at the lower side of the second pyrolysis transfer screw conveyor 142, and transfers the pyrolysis material transferred from the second pyrolysis transfer screw conveyor 142 to one side (for example, the left side). to the right, and at the same time, the third pyrolysis treatment is performed by heating the first and second gas burners 120 and 130. Since the rotation direction of the third pyrolysis transfer screw conveyor 143 is opposite to the rotation direction of the second pyrolysis transfer screw conveyor 142, the pyrolyzate subjected to the third pyrolysis treatment is in the opposite direction to the pyrolyzate subjected to the second pyrolysis treatment. is transported.

The fourth pyrolysis transfer screw conveyor 144 is connected to the transfer end portion at the lower side of the third pyrolysis transfer screw conveyor 143, and transfers Char, which is the final pyrolysis treatment product, transferred from the third pyrolysis transfer screw conveyor 143. It is discharged to the outside. At this time, a pipe may be provided at the transfer inlet of the fourth pyrolysis transfer screw conveyor 144 to discharge the generated oil vapor to the outside. In addition, tea, which is a pyrolysis treatment product discharged through the distal end of the fourth pyrolysis transfer screw conveyor 144, is discharged to the tea processing unit and treated.

Meanwhile, within the pyrolysis reactor body 110, a pair of first pyrolysis transfer screw conveyors 141 facing each other, a pair of second pyrolysis transfer screw conveyors 142 facing each other, and a pair of first pyrolysis transfer screw conveyors 142 facing each other. 3 The pyrolysis transfer screw conveyor 143 and the pair of fourth pyrolysis transfer screw conveyors 1441 facing each other are arranged to form a certain distance from each other. At this time, the first pyrolysis transfer screw conveyor 141 located at the top ), it has a structure in which the spacing between them becomes wider as it goes down to the fourth pyrolysis transfer screw conveyor 144 located at the bottom.

Due to this structure, the heat (heat flow) of the exhaust gas rises from the fourth pyrolysis transfer screw conveyor 144 to the first pyrolysis transfer screw conveyor 141 and gathers in the center, and at this time, a pair of first pyrolysis transfer screws On the upper side of the conveyor 141, the heat of the exhaust gas collected by the pair of first pyrolysis transfer screw conveyors 141 is temporarily confined and then the heat is discharged while surrounding the pair of first pyrolysis transfer screw conveyors 141. A bumper 111 for collecting exhaust gas may be provided.

The exhaust gas collection bumper 111 has a structure in which the heat of the exhaust gas concentrated in the upper center of the pyrolysis reactor main body 110 does not escape directly to the upper side and additionally heats the pair of first pyrolysis transfer screw conveyors 141. Because of this, heat transfer efficiency can be increased.

In addition, in the present invention, the lower inlet end is disposed at regular intervals along the longitudinal direction on the upper side of the pyrolysis reactor main body 110, and the upper discharge end may further include a combustion gas discharge duct 150 that is integrated into one.

The combustion gas exhaust duct 150 includes at least three lower inlet ends, and all lower inlet ends are connected to one upper discharge end. At this time, a damper for controlling the amount of combustion gas flowing into each lower inflow stage and a thermometer for determining the temperature of the combustion gas flowing into each lower inlet stage may be provided. Therefore, during the operation of the pyrolysis treatment device, the opening and closing amount of each damper is automatically adjusted according to the temperature measurement results within the pyrolysis reactor main body 110, so that the temperature within the pyrolysis reactor main body 110 can be maintained constant.

In one embodiment, the present invention provides a monitoring camera within the pyrolysis reactor main body 110 to prevent combustion efficiency from decreasing by constantly monitoring the combustion state of the burner within the pyrolysis reactor main body 110 and controlling the flame through this. can be installed.

In addition, in one embodiment, the present invention is connected to one side of the fourth pyrolysis transfer screw conveyor 144 within the pyrolysis reactor main body 110, and allows oil vapor to be discharged from the fourth pyrolysis transfer screw conveyor 144 together with the oil vapor. It may further include an internal duct that collects the discharged tar and reintroduces it into the fourth pyrolysis transfer screw conveyor 144.

The internal duct includes a duct for discharging oil vapor and a duct for transporting tar as a single structure within the pyrolysis reactor main body 110. This improves the tar removal rate when discharging oil vapor, and allows the discharging of oil vapor and re-introduction of tar to occur simultaneously. By doing so, clogging inside the duct can be prevented, and the oil vapor temperature can be increased by maximizing the circulation (rotation) time of the oil vapor, so the amount of gas used as a heat source of the first and second gas burners 120 and 130 can be reduced. There can also be advantages in reducing costs.

This internal duct may be connected to the upper part of the entrance side of each fourth pyrolysis transfer screw conveyor 144, and has a pyramid shape with a diameter that narrows from the bottom to the top.

The pyrolysis product is transferred to one side (for example, from left to right) and at the same time, the 3rd pyrolysis process is performed by heating the first and second gas burners 120 and 130. Likewise, a pipe may be provided at the transfer end of the third pyrolysis transfer screw conveyor 143 to discharge the generated oil vapor to the outside. Since the rotation direction of the third pyrolysis transfer screw conveyor 143 is opposite to the rotation direction of the second pyrolysis transfer screw conveyor 142, the pyrolyzate subjected to the third pyrolysis treatment is in the opposite direction to the pyrolyzate subjected to the second pyrolysis treatment. is transported.

Next, we will look at the overall configuration of the continuous waste synthetic resin pyrolysis treatment facility 200, which includes a pyrolysis treatment device using the multi-stage multi-row structure described above.

FIG. 3 is a diagram showing the overall configuration of a continuous waste synthetic resin pyrolysis treatment facility 200 including a pyrolysis treatment device using the multi-stage multi-row structure shown in FIG. 1.

Looking at Figure 3, the continuous waste synthetic resin pyrolysis treatment facility 200, which includes a pyrolysis treatment device with a multi-stage multi-row structure, is largely divided into a waste synthetic resin input unit 210, a pyrolysis treatment unit 220, a tea treatment unit 230, and oil vapor. It may be configured to include a heat exchange unit 240, an oil processing unit 250, and a gas processing unit 260.

The waste synthetic resin inlet 210 is largely comprised of an articulated crane 211 for injecting the waste synthetic resin, a hopper 212 for receiving the injected waste synthetic resin, and a machine installed in the longitudinal direction within the hopper 212 to stir the injected waste synthetic resin. A pair of stirring screws 213, a pair of compression screws 214 installed in the longitudinal direction at the lower side of the hopper 212 and supplying and simultaneously compressing the stirred waste synthetic resin in one direction, the pair of compression screws A pair of vertical stirring screws 215 and each vertical stirring screw are installed to be connected in a vertical direction at one end of (214), and transport the waste synthetic resin to the lower side and simultaneously release the waste synthetic resin in a compressed state. It is connected to (215) and may be configured to include a pair of supply screws (216) that supply the transferred waste synthetic resin to the pyrolysis transfer path.

The articulation crane 211 can be a three-stage articulation crane for the smooth introduction, packaging, storage, and loading of waste synthetic resin, which is the main raw material, into the hopper 212, and can be installed so that the working radius is 9.5 m.

The hopper 212 serves to accommodate a large amount of waste synthetic resin introduced through the articulated crane 211, and can be formed in an upper and lower shape with the upper and lower parts open. In addition, a pair of stirring screws 213 may be provided inside the longitudinal direction, and the waste synthetic resin is discharged through a pair of open areas provided on the lower side. At this time, each open area has a pair of compression screws. A screw 214 is provided.

A pair of stirring screws 213 serve to agitate a large amount of waste synthetic resin introduced into the hopper 212. At this time, the stirring drive motor, the stirring shaft that rotates by being coupled to the rotation axis of the stirring drive motor, and the outer peripheral surface of the stirring shaft It may be configured to include a spiral stirring blade provided along. The pair of stirring screws 213 can be more easily compressed through the pair of compression screws 214 by breaking or loosening a large amount of waste synthetic resin input into the hopper 212 if it is lumped or pressed. Let it be.

Meanwhile, the pair of stirring screws 213 are installed parallel to each other while maintaining a certain distance (for example, 150 mm) from each other within the hopper 212, and at this time, the compression of the pair of compression screws 214 It rotates in the direction opposite to the direction (direction of rotation).

A pair of compression screws 214 are provided below a pair of open areas provided in the longitudinal direction (lengthwise) at the bottom of the hopper 120, and supply waste synthetic resin discharged through the pair of open areas in one direction. At the same time, it serves to compress the waste synthetic resin.

This pair of compression screws 214 is a pair of conveyor ducts (or conveyor pipes) communicating with a pair of open areas provided in the lower part of the hopper 212, and a pair of compression drives provided in the pair of conveyor ducts. It may be configured to include a motor, a rotation shaft coupled to the rotation axis of the compression drive motor and extending in the longitudinal direction of the conveyor duct, and a compression screw provided along the outer peripheral surface of the rotation shaft.

At this time, the compression screw transfers the waste synthetic resin in the rotational direction through its spiral structure, and the pitch may be gradually narrowed based on the transfer direction. Accordingly, the compression efficiency through the pair of compression screws 214 can be increased by increasing the conveying speed due to the narrowing pitch.

The waste synthetic resin compressed and transferred through a pair of compression screws 214 is transferred to a pair of vertical stirring screws 215.

A pair of vertical stirring screws 215 are installed to be connected in the vertical direction at one end of the pair of compression screws 214, and simultaneously transport the conveyed waste synthetic resin in a downward direction. It plays a role in releasing the compressed waste synthetic resin.

The pair of supply screws 216 are each connected to the lower part of the vertical stirring screw 215, and serve to supply the waste synthetic resin transferred through the pair of vertical stirring screws 150 to the pyrolysis transfer path.

Meanwhile, although not shown in the drawing, the present invention may further include a catalyst input unit (not shown). The catalyst introduced through the catalyst inlet is preferably zeolite, and more preferably slaked lime (calcium hydroxide). This is to reduce the cost of catalyst input.

Additionally, zeolite or slaked lime may be used as the catalyst. At this time, the zeolite contains SiO2 62.2-75.0 wt%, Al2O2 10.0-21.0 wt%, Na2O 1.5-5.0 wt%, K2O 1.7-3.5 wt%, CaO 0.8-2.5 wt%, Fe2O2 0.5-1.8 wt%, and 0.5 wt% of other components. It contains ~1.8 wt%, and the loss on ignition is 5.2~15.3 wt%, and other components may include FeO, TiO2, P2O5, and MnO. Additionally, the pH of the zeolite may be 9.0 to 10.5, and the cation exchange capacity (CEC) may be 80 to 92 meq/100g. Slaked lime may contain more than 70% of CaO, less than 2% of SiO2, less than 3% of MgO, less than 1% of Fe2O3, and less than 1% of Al2O3, and preferably does not contain sulfur.

In addition, the slaked lime has a particle size that allows more than 95% of the slaked lime to pass through a 325 mesh sieve. Specifically, it is desirable to have a particle size that allows 96.58% of the slaked lime to pass through a 325 mesh sieve.
