Description

Apparatus for restoring plastic to oil

The present invention relates to an emulsification reduction apparatus for plastics, and more particularly, to an apparatus for cooling a gas generated by dissolving plastics to produce an emulsified solution.

In order to reduce environmental pollution caused by waste plastics, a method of reducing waste plastics with renewable oils such as heavy oils has been widely used. This reduction process consists of collecting gas generated by dissolving the plastic and cooling the collected gas to obtain an emulsified solution. However, in the related art, a process of dissolving the plastic at a low temperature and a process of generating the decomposition gas by heating the dissolved plastic at a high temperature have been performed in separate apparatuses. Therefore, there has been a problem that the device is large in size and is not suitable for treating a small amount of plastic.

In order to solve this problem, the proposed method is characterized by performing both the dissolution and decomposition gas generation in one pyrolysis tank. That is, the plastic in the solid state is stored and dissolved, and the dissolved plastic is continuously heated to generate decomposition gas. However, when the plastic in the solid state is dissolved, the volume decreases, and thus heating the entire dissolution tank until decomposition gas occurs is inefficient and wastes power.

In addition, when the decomposition gas is cooled in the cooling tank to generate regenerated oil, a process of separating the regenerated oil into separate components such as heavy oil is required. Since this process is also performed in a separate device, the overall device is also large and not suitable for processing small quantities of plastic.

The technical problem to be achieved by the present invention is to provide an emulsification reduction apparatus for plastics that can reduce the power consumed in the process of dissolving plastics to produce regenerated oil.

In order to achieve the above technical problem, the emulsion reduction apparatus of a plastic according to the present invention, the receiving space is formed therein, the melting furnace capable of sealing by the upper cover; An outer container accommodating the melting furnace and provided with a coil for dissipating heat on an inner side thereof; And a control circuit for independently supplying current to the upper coil provided on the inner side of the outer container and the lower coil provided on the lower portion of the upper coil.

According to the emulsification reduction apparatus of the plastic according to the present invention, by separating the coil for supplying heat to the melting furnace into the upper coil and the lower coil to supply the current, respectively, the space corresponding to the upper coil according to the volume of the plastic contained in the melting furnace and Since the temperature of the space corresponding to the lower coil can be adjusted individually, waste of power can be reduced. In addition, by forming the inner wall of the outer container by the refractory brick, it is efficient because the radiant heat can be supplied to the melting furnace for a long time even after the power supply to the coil is stopped. Furthermore, by providing a reflecting plate on the inner side of the groove in which the coil is located, the heat efficiency from the coil is reflected and supplied to the melting furnace, thereby improving the thermal efficiency.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the emulsification reduction apparatus of a plastic according to the present invention.

1 is a view showing the configuration of a preferred embodiment of the emulsification reduction apparatus of a plastic according to the present invention.

Referring to FIG. 1, the emulsification reduction apparatus of plastic according to the present invention includes an outer container 110, a melting furnace 120, a cooling tank 130, and a control circuit 140.

The outer container 110 serves to supply heat to the melting furnace 120 for dissolving the plastic. The melting furnace 120 has an accommodating space formed therein to accommodate the material to be treated, for example, plastic, and has a sealable structure. In addition, the inner side of the outer container 110 is provided with coils 112 and 114 for dissipating heat by receiving current. The coils 112 and 114 are composed of an upper coil 112 and a lower coil 114 positioned below the upper coil, and the control circuit 140 is independently of the upper coil 112 and the lower coil 114, respectively. Supply the current. Specifically, a method of controlling the current supplied to the upper coil 112 and the lower coil 114 will be described later.

The inner wall of the outer container 110 may be constituted by a plurality of refractory bricks. The refractory brick is resistant to high temperatures and does not dissipate heat well. Thus, even when the current supply to the coils 112 and 114 is stopped, the radiant heat emitted from the inner wall of the outer container 110 for a considerable period of time is dissolved in the furnace 120. Since it can supply to, it has the effect of reducing the power consumption. However, the inner wall of the outer container 110 may be made of another material having similar properties to the fire brick.

When the outer container 110 is made of refractory bricks, grooves for installing the coils 112 and 114 are formed on one surface of each of the refractory bricks forming the inner surface of the outer container 110.

2 is an enlarged view illustrating an inner side surface of the outer container 110 in which the coils 112 and 114 are installed. Referring to FIG. 2, grooves 212 are formed on one surface of the firebrick 210 constituting the inner wall of the outer container 110, and coils 112 and 114 are positioned in the inner space of the grooves 212. The number of grooves 212 formed in one firebrick 210 is set according to the amount of heat emitted from the coils 112 and 114 to be installed. In addition, in order to ensure that the coils 112 and 114 are stably positioned, the shape of the grooves 212 is preferably in the shape of a circle or an ellipse when viewed from the side as shown in FIG. 2.

A reflector plate 214 may be installed on the inner side surface of the groove 212 to allow the heat emitted from the coils 112 and 114 to be transmitted to the melting furnace 120 as much as possible without being absorbed by the refractory brick 210. In this case, when the reflecting plate 214 is installed to extend in a form surrounding the inner surface of the outer container 110, deformation such as expansion or contraction occurs due to heat radiated from the coils 112 and 114, and thus the coils 112, 114) may also be affected. Therefore, as shown in FIG. 2, the reflective plate 214 may be formed to be short so that the plurality of reflective plates 214 may be detachably installed on the inner surface of the groove 212 at regular intervals. Since the length of the reflector 214 is shortened, deformation by heat can be prevented. In addition, when the reflective plate 214 is detachably installed, there is an advantage that it is easy to install and replace.

In addition, due to the characteristics of the reflector 214, which must have a property of reflecting heat, when the reflector 214 is present, heat emitted from the coils 112 and 114 may be transferred to the reflector 214, so that a substantial portion thereof is transmitted. In order to minimize the amount of heat, the coils 112 and 114 may be installed to be spaced apart from the reflecting plate 214. To this end, a means for fixing the coils 112 and 114 to the grooves 212 while being spaced apart from the reflecting plate 214 is required.

3 is a view showing the installation form of the coils 112 and 114 when the reflecting plate 214 is not installed, and FIG. 4 shows the outer container 110 and the melting furnace 120 when the reflecting plate 214 is installed. It is the figure which expanded the space between. 3 and 4, the inner wall of the outer container 110 is composed of a plurality of refractory bricks 210, and the heat absorbed by the refractory bricks 210 is outwardly toward the outside of the refractory bricks 210. Insulation material 220 is disposed so as not to be discharged. In this way, the firebrick 210, the heat insulating material 220, and the outer wall 230 surrounding the outside form the outer container 110. It can be seen from FIG. 3 and FIG. 4 that the melting furnace 120 is spaced apart from the outer container 110.

Referring to FIG. 3, when the reflecting plate 214 is not installed, it is unlikely that heat emitted from the coils 112 and 114 is transferred to the firebrick 210. Thus, the coil does not necessarily have to be spaced apart from the inner side of the groove 212.

However, when the reflecting plate 214 is installed on the inner side of the groove 212 as shown in FIG. 4, the coils 112 and 114 are spaced apart from the reflecting plate 214, and are connected to the groove 212 by the connecting pin 216. It is fixed. The connecting pin 216 is preferably made of a material which is not thermally conductive or small, and the connecting pin 216 may be disposed at the reflecting plate 214 to minimize heat transfer from the coils 112 and 114 to the reflecting plate 214. A hole may be formed in the portion to be disposed so that the coils 112 and 114 do not directly contact the reflector plate 214. Alternatively, when the reflecting plate 214 is installed as shown in FIG. 2, since the inner surface of the groove 212 is exposed between the neighboring reflecting plates 214, the connecting pin 216 is disposed at the corresponding portion. can do.

5A and 5B illustrate an example in which a reflecting plate 214 is installed in a groove 212 having a parabolic shape. 5A and 5B, when the shape of the groove 212 is a parabola, heat emitted from the coils 112 and 114 is reflected horizontally from the reflecting plate 214 and transferred to the melting furnace 120. Efficiency can be improved. However, when the shape of the groove 212 is a parabola, the reflection plate 214 is more likely to be separated from the groove 212 when the removable reflection plate 214 is installed than in the case shown in FIGS. 3 and 4. Accordingly, as shown in FIG. 5B, a small groove may be formed in the inlet portion of the groove 212, and the shape of the reflecting plate 214 may also correspond to fix the reflecting plate 214 to the groove 212.

FIG. 6 is a view illustrating a form in which coils 112 and 114 are removed from an inner side surface of the outer container 110 shown in FIG. 2. Referring to FIG. 6, the connecting pins 216 connecting the inner surfaces of the grooves 212 and the coils 112 and 114 are disposed in a space between the neighboring reflecting plates 214 so that the coils 112 and 114 and the reflecting plates ( 214 can be prevented from making direct contact. 7A and 7B illustrate various types of connection pins 216. The connecting pin 216 of the type shown in FIG. 6 is connected to the side surfaces of the coils 112 and 114 to fix the coils 112 and 114. In this case, however, only one side of the coil is fixed and not stable. On the other hand, since the connecting pins 216 having the shape shown in FIGS. 7A and 7B have a shape surrounding the lower portions of the coils 112 and 114, the coils 112 and 114 may be more stably supported. In particular, since the connecting pin 216 of the type shown in FIG. 7B is not connected to one point of the coils 112 and 114 but supports a large area, the coils 112 and 114 are most stably fixed to the grooves 212. You can.

8 is a view showing a detailed configuration of the outer container 110 and the melting furnace 120 shown in FIG. Referring to FIG. 8, the melting furnace 120 is spaced apart from the outer container 110 having the configuration as described above, and the space between the outer container 110 and the bottom surface of the melting furnace 120 is the melting furnace 120. Is formed by a support 128 spaced apart from the outer container 110. In this case, the support 128 is located at a portion where the coil 114 is not installed on the inner wall of the outer container 110. Since the outer wall of the melting furnace 120 and the inner wall of the outer container 110 are not in direct contact with each other, the melting furnace 120 receives heat in the form of radiant heat from the coils 112 and 114 installed on the inner wall of the outer container 110. Dissolve the plastics stored inside. When the melting furnace 120 is spaced apart from the outer container 110, the inner space of the melting furnace 120 may be evenly heated as compared with the direct contact.

As described above, since the coils 112 and 114 are separated into the upper coil 112 and the lower coil 114, the inner space of the melting furnace 120 is surrounded by the upper coil 112 to draw heat from the upper coil 112. Surrounded by the supply space and the lower coil 114 is separated into a space receiving heat from the lower coil 114. When the plastic in the solid state accommodated in the melting furnace 120 is dissolved and becomes a liquid state, the volume is reduced. Therefore, at first, the plastic is located in the space surrounded by the upper coil 112 and the lower coil 114, but when the plastic dissolves over time, the overall volume decreases, and the plastic dissolved only in the space surrounded by the lower coil 114 It may happen that you are located. In this case, heating the entire furnace 120 by continuously supplying current to both the upper coil 112 and the lower coil 114 is a waste of power.

Therefore, when the coils 112 and 114 are separated into the upper coil 112 and the lower coil 114 as in the present invention, the control circuit 140 cannot reach the space surrounded by the molten plastic by the upper coil 112. When it is determined that the current supplied to the upper coil 112 is cut off, it is possible to reduce the waste of power. For example, if the total time to dissolve all the plastic in the melting furnace 120 is 2 hours, the control circuit 140 is supplied to the upper coil 112 at the time 50 minutes after the dissolution process of the plastic is started. Can cut off the current. In addition, the control circuit 140 may control the supply of current according to the temperature of the inner space of the melting furnace 120.

To this end, the emulsion reduction apparatus according to the present invention is the melting furnace 120 surrounded by the upper coil 112 to adjust the current supplied to the upper coil 112 and the lower coil 114 according to the internal temperature of the melting furnace 120. It further includes a lower temperature sensor 118 for measuring the temperature of the inner space of the melting furnace 120 surrounded by the upper temperature sensor 116 and the lower coil 114 to measure the temperature of the inner space of the. The control circuit 140 controls the current supplied to the upper coil 112 and the lower coil 114 based on the temperature measured by the upper temperature sensor 116 and the lower temperature sensor 118.

The control circuit 140 first heats the melting furnace 120 by supplying current to both the upper coil 112 and the lower coil 114. Therefore, the temperature of the entire inner space of the melting furnace 120 is increased. At this time, when the temperature measured by the upper temperature sensor 116 becomes a predetermined first reference temperature, for example, 300 ° C, the control circuit 140 cuts off the current supplied to the upper coil 112. As described above, the melting furnace 120 receives heat from the outer container 110 in the form of radiant heat, and the current is no longer supplied to the coils 112 and 114 due to the characteristics of the refractory brick forming the inner wall of the outer container 110. If not, the temperature may be maintained for a long time and heat may be supplied to the melting furnace 120. In addition, the control circuit 140 controls the current supplied to the lower coil 114 so that the temperature measured by the lower temperature sensor 118 is maintained between the second reference temperature and the third reference temperature that is set in advance. That is, the space surrounded by the lower coil 114 always maintains a constant temperature. In this case, the second reference temperature and the third reference temperature may be set higher than the first reference temperature, and may be set to maintain a temperature near 497 ° C and 503 ° C, that is, 500 ° C, respectively. In addition, the temperature of the entire inner space of the melting furnace 120 is maintained at about 300 ℃ ~ 450 ℃.

As mentioned above, the melting furnace 120 dissolves the material to be treated, ie, plastic, stored therein by using radiant heat supplied from the outer container 110. The plastic housed in the melting furnace 120 is preferably shredded to a certain size so as to be easily dissolved. The melting furnace 120 is closed by the upper flange 121 and the lower flange 122 during the dissolution process of the plastic. The decomposition gas generated by dissolving the plastic is discharged from the melting furnace 120 through the gas transport pipe 125 and collected by the cooling tank 130 for the emulsification process.

At this time, the gas discharged from the melting furnace 120 may contain impurities such as wax components of the plastic mixture. When such impurities are transferred to the cooling tank 130 as it is, the secondary impurity removal operation by the filtering device should be performed on the emulsion solution generated in the cooling tank 130. Therefore, the emulsion reduction apparatus according to the present invention for the efficiency of the emulsification process may further include a gas dust collector 123 is installed on the upper cover of the melting furnace (120). The gas dust collector 123 is installed between the lid of the upper flange 121 of the melting furnace 120 and the gas transportation pipe 125, and includes a strainer 124 to decompose the gas discharged from the melting furnace 120 into the gas transportation pipe. Impurities can be effectively removed before entering 125. A support may be installed below the sieve 124 in the gas dust collecting unit 123 to support the sieve 124.

In this case, when the decomposition gas passes through the gas dust collecting unit 123, the speed of the decomposition gas discharged to the cooling tank 130 may be slower than that of the decomposition gas in the melting furnace 120, and the melting furnace 120 and the gas may be reduced. Vortex phenomena may occur between the dust collectors 123. Therefore, it is preferable that the lower width of the gas dust collecting part 123 is designed to be equal to the width of the melting furnace 120. 9A and 9B illustrate the shape of the gas dust collector 123. Referring to FIG. 9A, the gas dust collecting part 123 is designed to have a cylindrical shape, and the width of the portion where the sieve 124 is positioned and the portion where the decomposition gas is collected under the sieve 124 are the same. Referring to FIG. 9B, the width of the gas dust collector 123 is gradually increased from the bottom of the sieve 124 so that the amount of decomposition gas collected at the same time increases.

The exhaust port 127 connected from the side surface of the melting furnace 120 to the outer wall of the outer container 110 is completed with the cooling fan 126 installed on the outer wall of the outer container 110 after the melting process of the plastic is completed. It is provided for cooling. The exhaust port 127 and the cooling fan 126 may be installed in a space surrounded by the upper coil 112 and a space surrounded by the lower coil 114, respectively.

After the melting process is completed, the plastics may be additionally dissolved using residual heat inside the melting furnace 120 without forcibly cooling the inside of the melting furnace 120 by the exhaust port 127 and the cooling fan 126. To this end, the re-inlet 150 is installed on the upper cover of the melting furnace 120. The re-entry 150 has a lower stopper 151 and an upper stopper 153 to prevent the decomposition gas inside the melting furnace 120 from being discharged outward. The opening and closing of the lower stopper 151 is made by the lower valve 152, and the opening and closing of the upper stopper 153 is made by the upper valve 154. The upper stopper 153 is installed on the outside of the re-entry 150, but may be designed in the form of a lid instead of being opened and closed by a valve, but the lower stopper 151 is located inside the re-entry 150. It should be designed in such a way that the opening and closing by the lower valve (152). In addition, the side of the re-entry 150 may be formed of a heat insulating material to prevent heat generated while the plastic is dissolved in the melting furnace 120 through the re-entry 150, and the re-entry 150 for aesthetics. A cover (not shown) may be further installed on the outer side of the cover.

10A and 10B are views showing shapes when the lower plug 151 is closed and open, respectively. 10A and 10B, the lower stopper 151 is connected by the lower valve 152 and the plate-shaped accommodating part, and the plate-shaped accommodating part is hollowed out so that the lower stopper 151 is accommodated. Has When the lower valve 152 is rotated to open the lower stopper 151, the lower stopper 151 is accommodated in the accommodating part as illustrated in FIG. 10B to connect the inside of the melting furnace 120 and the re-inlet 150. As such, a structure such as a lower valve 152 that moves the lower cap 151 to the left and right to open and close the tube is called a light gate valve.

When additional plastic is to be added through the re-inlet 150, first, the upper cap 153 is opened by the upper valve 154, the plastic is injected into the re-inlet 150, and the upper cap 150 is closed. Since the lower plug 151 is blocked, the injected plastic is positioned between the lower plug 151 and the upper plug 153. Next, the lower cap 151 is opened to inject plastic into the melting furnace 120, and the lower cap 151 is closed again. Thus added plastic is dissolved by the residual heat in the melting furnace 120, the generated decomposition gas is delivered to the cooling tank 130 via the gas transport pipe (125).

In another embodiment, the plastic may be further added through the re-inlet 150 during the dissolution process in the melting furnace 120, but in this case, the decomposition gas inside the melting furnace 120 may reintroduce the re-inlet 150. Since it may be discharged through, it is preferable to add the plastic after the dissolution process is finished.

According to one embodiment of the outer container 110 and the melting furnace 120 shown in Figure 8 when designing the emulsion reduction apparatus of the plastic according to the present invention, the specifications of each part is as follows.

Height of the melting furnace 120: 500mm

Width of the furnace 120: 276mm

Melting furnace (120) wall thickness: 6mm

Spacing between coils 112 and 114: 50 mm

Diameter of the exhaust port 127: 60 mm

Diameter of the gas dust collector 123: 200 mm

Re-inlet 150 diameter: 89mm

Reinsertion hole 150 length: 500 mm

On the basis of the above specifications, if you design the emulsion reduction device of plastics according to the present invention

11 is a view showing a detailed configuration of the cooling tank 130 shown in FIG. The cooling tank 130 collects and cools down the decomposition gas discharged by dissolving the plastic in the melting furnace 120 to generate a regeneration oil 139 which is an emulsified solution. To this end, the internal space of the cooling tank 130 collects the recycled oil in which the recycled oil generating space 162 and the generated recycled oil 139 gather together to cool the cracked gas by the coolant 133 to generate the recycled oil 139. It is divided into spaces 164.

The collected decomposition gas is directly injected into the coolant 133 located in the regeneration oil generating space 162, and the coolant 133 is introduced through the coolant inlet 137 installed in the cooler cover 131 to perform an emulsification process. After it is discharged through the cooling water outlet 136. In addition, when the decomposition gas discharged from the melting furnace 120 is introduced into the cooling tank 130 through the gas transport pipe 125, the backflow shutoff valve 132 prevents the decomposition gas from flowing back to the melting furnace 120 again. . When the coolant 133 is filled up to the upper end of the regeneration oil generating space 162, when the coolant 133 is additionally introduced through the coolant inlet 137, the coolant 133 is regenerated by the surface of the coolant. 164). Therefore, a boundary membrane 134 having a network structure is installed between the regeneration oil generation space 162 and the regeneration oil collection space 164 to stabilize the surface of the cooling water 133.

The regenerated oil 139 generated in the regenerated oil generating space 162 forms a layer separated from the coolant 133, and is located at the top because the specific gravity is smaller than that of the coolant 133. When the regeneration oil 139 is generated in a predetermined amount or more, it passes through the boundary membrane 134 on the top of the regeneration oil generating space 162 and collects in the regeneration oil collection space 164. The regeneration oil 139 of the regeneration oil collection space 164 is discharged to the outside through the regeneration oil outlet 135.

In order to separate the regeneration oil 139 generated in the cooling tank 130 into kerosene and diesel, a separate treatment process is required. For this purpose, the regeneration oil 139 may be added to the melting furnace 120 to perform a separation process in the melting furnace 120. That is, after the dissolution process of the plastic in the melting furnace 120 is finished, the temperature inside the melting furnace 120 is sufficiently lowered by using the cooling fan 126 and the exhaust port 127 and the regeneration oil 139 is introduced. Thereafter, the melting furnace 120 is gradually heated to sequentially extract gasoline, kerosene, diesel and heavy oil from the regeneration oil 139. As described above, the separation process of the regeneration oil 139 is performed in the melting furnace 120 so that it is not necessary to provide a separate device for the separation of the regeneration oil 139. It can be used suitably for processing.

On the other hand, when the emulsification process of the decomposition gas is performed in the cooling tank 130, a by-product made of a gas such as water vapor may occur. These by-products are discharged from the cooling tank 130 through the gas outlet 138 and the gas discharge pipe 610, all of them can be burnt and removed by the incineration heater 620.

12 is a flowchart illustrating an overall process of generating regenerated oil by dissolving and emulsifying plastics.

Referring to FIG. 12, first, the plastic to be dissolved is introduced into the melting furnace 120 (S1110). Plastics can be crushed and added to facilitate dissolution. Next, the control circuit 140 supplies current to the upper coil 112 and the lower coil 114 installed on the inner side of the outer container 110, and heat dissipated from the coils 112 and 114 is the melting furnace 120. It is supplied to (S1120). The temperature of the space surrounded by the upper coil 112 and the space surrounded by the lower coil 114 in the inner space of the melting furnace 120 is measured by the upper temperature sensor 116 and the lower temperature sensor 118, respectively. The control circuit 140 controls the current supplied to the lower coil 114 to maintain the temperature measured by the lower temperature sensor 118 between the second reference temperature and the third reference temperature. In addition, when the temperature measured by the upper temperature sensor 116 is greater than or equal to a predetermined first reference temperature (S1130), the supply of current to the upper coil 112 is stopped (S1140).

The cooling tank 130 collects the gas discharged by dissolving the plastic in the melting furnace 120 (S1150). In the cooling tank 130, the regeneration oil 139 is generated by cooling and emulsifying the gas by the cooling water 133 (S1160). The generated regenerated oil 139 is added to the cooled melting furnace 120 after the dissolution process of the plastic is finished (S1170). As the melting furnace 120 is gradually heated again, gasoline, kerosene, light oil and heavy oil may be sequentially separated (S1180).
