Japanese Patent No. 4950690

In this oiling device, a vaporizing container containing waste plastic such as a bottle cap as a raw material is heated to a predetermined temperature determined by the material of the waste plastic and the waste plastic is melted and vaporized. By cooling the vaporized gas in the process of passing through the condenser, the vaporized gas is condensed (liquefied) to refine the hydrocarbon oil.

In this oil vaporizer, the vaporization container has a bottomed cylindrical shape, and an electric heater for heating the vaporization container is wound around and fixed to the outer periphery of the vaporization container. For this reason, the oil vaporizer is not configured so that the vaporizer can be detached from the oil vaporizer, and even when it is desired to continue processing the waste plastic, the heated vaporizer is cooled to a predetermined temperature. Without waiting for this, the waste plastic to be processed next could not be put into the vaporization container.

As described above, in this type of oil making apparatus, waste plastics are processed in a batch manner, and when the waste plastics are continuously processed, there is a waiting time for the heated vaporization container to cool to a predetermined temperature. Since this occurs, the cycle time of the oil generator becomes long.

A pipe connecting the vaporization container and the condenser and supplying the vaporized gas to the condenser is provided with a separation mechanism that can separate the vaporization container from the condenser,
The heating unit is configured to heat the vaporization container placed on the heating unit.

According to the present invention, by separating the vaporization container from the condenser by the separation mechanism, the vaporization container placed on the heating means can be taken out from the small oil vaporization apparatus. The container can be removed from the compact oil making apparatus without waiting for the container to cool to a predetermined temperature.
Therefore, by preparing a plurality of vaporization containers in which waste plastic is charged in advance, the waste plastic can be continuously processed in a batch manner.

Then, after joining the pipe 35 of the vaporization vessel 3 and the pipe 45 of the condenser 4, the pipe 35 and the pipe 45 are connected by a clamp 46. And the door member 2b is moved to the arrow direction in the figure, and the opening part 20b3 of the case 2 is sealed with the door member 2b.

Then, as shown in FIG. 7B, the door member 2c of the case 2 is opened, and the refrigerant Wa is injected into the storage unit 41 of the condenser 4 from the opened opening 20c1. At this time, the refrigerant Wa is stored up to a position higher than the heat exchanger 42 disposed in the storage unit 41, and the heat exchanger 42 is immersed in the refrigerant Wa.
After the refrigerant Wa is stored up to a height at which the heat exchanger 42 in the storage unit 41 is immersed, the door member 2c of the case 2 is closed to close the opening 20c1.

Next, when the power of the compact oil refiner 1 is turned on, the temperature of the ceramic heater 5 is adjusted by the control unit 9 (see FIG. 1B). The controller 9 adjusts the temperature of the ceramic heater 5 based on the output result of a temperature sensor (not shown) provided in the vaporization container 3.

As shown in FIG. 8A, the waste plastic in which the ceramic heater 5 is heated by the temperature control by the control unit 9 and the temperature of the vaporization vessel 3 placed thereon is put into the vaporization vessel 3. When it becomes higher than the melting point of PL, the waste plastic PL is melted (see FIG. 8B).
When the ceramic heater 5 is further heated and the temperature in the vaporization vessel 3 becomes higher than a predetermined vaporization temperature, the molten waste plastic PL is vaporized and vaporized gas PLG is generated (see FIG. 8C). ).

As shown in FIG. 8C, the vaporized gas PLG generated by vaporizing the waste plastic PL passes through the pipe 35 and the pipe 45 provided on the top wall 3 c of the vaporization container 3, and the gas in the heat exchanger 42. It flows into the space 432b of the introduction part 43 (see the arrow in the figure). The vaporized gas PLG that has flowed into the space 432b is distributed from the space 432b to each flow pipe 44, and moves in the flow pipe 44 toward the oil discharge portion 48.

Here, the heat exchanger 42 is immersed in the refrigerant Wa, and each flow pipe 44 of the heat exchanger 42 is in a state cooled by the refrigerant Wa. Therefore, when the vaporized gas PLG passes through each flow pipe 44, it is cooled and condensed (liquefied) to purify the hydrocarbon oil POL.

The hydrocarbon oil POL flows through the flow pipe 44 inclined so as to become lower from the gas introduction part 43 toward the oil discharge part 48 and moves to the oil discharge part 48.
Then, the hydrocarbon oil POL that has moved to the oil discharge part 48 is stored in the storage container 6 through a pipe 49 a provided in the lower part of the oil discharge part 48.

Here, when the vaporized gas PLG does not condense (liquefy) when passing through the flow pipe 44 of the heat exchanger 42, the vaporized gas PLG passes through the flow pipe 44 together with the hydrocarbon oil POL. It moves to the oil discharge part 48. Then, the vaporized gas PLG is discharged to the atmosphere through an exhaust gas pipe 49b provided at the upper part of the oil discharge part 48 and the catalyst 7 for removing harmful components of the vaporized gas PLG. for that reason. The vaporized gas PLG after the harmful components are removed by the catalyst 7 is released to the atmosphere.

Also, the hydrocarbon oil POL that has not been discharged from the pipe 49 a and has accumulated at the bottom of the oil discharge section 48 is stored in the storage container 6 through the drain pipe 49 c provided at the bottom of the oil discharge section 48. It has become.

When the liquefaction treatment of the waste plastic PL charged into the vaporization container 3 is completed, the door member 2b of the case 2 is opened and the clamp 46 is removed in order to charge the next waste plastic PL into the vaporization container 3. After separating the vaporization vessel 3 and the condenser 4, the vaporization vessel 3 after the oiling treatment is taken out. At this time, the vaporization vessel 3 after the oil treatment is heated to a high temperature by the ceramic heater 5, but the vaporization vessel 3 and the condenser 4 are simply removed by removing the clamp 46 that connects the pipe 35 and the pipe 45. Since the vaporization container 3 is only placed on the placement surface 51 of the ceramic heater 5, the vaporization container 3 can be removed from the ceramic heater 5 and easily removed from the space S1 of the case 2. It has become.

Then, another vaporization container 3 into which the waste plastic PL to be oiled next is placed in advance is placed on the placement surface 51 of the ceramic heater 5, and the door member 2b is closed.

Then, the power supply of the small oil vaporizer 1 is turned on, and the temperature of the ceramic heater 5 on which the vaporization container 3 is placed is adjusted so that the vaporization container 3 becomes equal to or higher than the vaporization temperature of the waste plastic PL, and the vaporization container 3 The waste plastic PL inside is melted and vaporized. Then, the vaporized gas PLG generated by vaporizing the waste plastic PL is cooled and condensed (liquefied) by the condenser 4 to purify the hydrocarbon oil POL condensed with the vaporized gas PLG.

In this way, by preparing a plurality of different vaporization containers 3 charged with the waste plastic PL in advance and replacing them with the vaporization containers 3 that have been subjected to the oily treatment, the oily treatment is continuously performed in a batch manner. be able to.

Moreover, when the bottle main body 62 of the storage container 6 is filled with the refined hydrocarbon oil POL, only the bottle main body 62 is removed from the bottle cap 61 and a new bottle main body 62 is attached to the bottle cap 61. The storage container 6 can be easily replaced.

Here, as described above, in the condenser 4, the fixing

members

434 and 484 fastened with bolts and nuts are removed, whereby the flow pipe 44 connected to the

connection members

431 and 481 is connected to the condenser 4. Can be removed from.
In particular, since each flow pipe 44 is formed in a straight line shape, it is possible to easily clean the flow pipe 44 by removing the fixing

members

434 and 484 and removing the flow pipe 44 from the condenser 4. Can do. Further, even when any one of the plurality of flow pipes 44 is clogged, maintenance can be easily performed by removing and replacing the corresponding flow pipes 44 individually.

The refrigerant Wa of the condenser 4 is indirectly in contact with the hydrocarbon oil POL via the flow pipe 44 of the heat exchanger 42, so that the hydrocarbon oil POL is not mixed with the refrigerant Wa and contaminated. However, when the refrigerant Wa of the condenser 4 is replaced, the refrigerant Wa can be easily discharged simply by opening the valve 8a connected to the refrigerant drain pipe 49d (see FIG. 1).

Further, when the inside of the vaporization container 3 is dirty, after the vaporization container 3 is taken out from the small oil vaporization apparatus 1, the lid member 34 can be removed and a washing apparatus can be inserted from the inlet 32 to clean the inside. Alternatively, the door member 2a of the case 2 may be opened, and a cleaning device may be inserted into the charging port 32 opened from the opening 20b4 for cleaning.

(1) As described above, in the embodiment, the vaporization container 3 that stores the waste plastic PL (resin material) that is a raw material, and the vaporization container 3 is heated to a predetermined temperature that is vaporized after melting the waste plastic PL. A ceramic heater 5 (heating means) and a condenser 4 that cools and condenses the vaporized gas PLG generated by vaporizing the waste plastic PL, and carbonizes by condensation of the vaporized gas PLG generated from the waste plastic PL. A small-sized oil purification apparatus 1 for purifying hydrogen oil POL, which connects a vaporization container 3 and a condenser 4 to pipes (pipes 35 and 45) for supplying vaporized gas PLG to the condenser 4. Is provided so as to be separable from the condenser 4, and the ceramic heater 5 is connected to the ceramic. And configured to heat the evaporation vessel 3 placed on the over motor 5.

If comprised in this way, since the vaporization container 3 is only mounted in the ceramic heater 5 easily and removal from the ceramic heater 5 is easy, the vaporization container 3 is removed from the condenser 4 with a separation mechanism. By making it separate, the vaporization container 3 can be easily taken out from the small oil making apparatus 1. Thereby, the vaporization container 3 heated with the ceramic heater 5 can be taken out from the small oil-ized apparatus 1 without waiting for the vaporization container 3 to cool to predetermined temperature.
Therefore, by preparing a plurality of vaporization containers 3 into which the waste plastic PL is charged in advance, the waste plastic PL can be continuously processed in a batch manner.

Moreover, in the conventional oil vaporization apparatus, the electric heater for heating a vaporization container is wound around the vaporization container, and in order to transmit the heat of this electric heater efficiently to a vaporization container, The periphery of the heater (vaporization vessel) was covered with a heat insulating member. As a result, the heat of the electric heater is kept warm by the heat insulating member, and the heat of the electric heater is efficiently transmitted to the vaporization container.
However, in the conventional oil vaporization apparatus, since the periphery of the electric heater (vaporization container) is covered with a heat insulating member, the high-temperature heat of the vaporization container after the oiling treatment is difficult to escape outside beyond the heat insulation member. It was a bad thing. Therefore, a longer waiting time is required to wait for the vaporization container to cool to a predetermined temperature, and the cycle time of the oilifier cannot be shortened.

In the present invention, since the vaporization vessel 3 is merely placed on the ceramic heater 5 (heat insulation member 22), the vaporization vessel 3 can be easily separated from the ceramic heater 5 (heat insulation member 22). Only the container 3 can be cooled in a short time by a method such as air cooling.
Therefore, since the waiting time for waiting for the vaporization container 3 to cool to a predetermined temperature can be shortened, even when a plurality of vaporization containers 3 are not prepared, the waste plastic PL can be continuously processed in a batch manner. The cycle time of the converter can be shortened.

(2) The pipe is composed of a pipe 35 (first pipe) fixed to the vaporization vessel 3 and a pipe 45 (second pipe) fixed to the condenser 4. The pipe 35 and the pipe 45 are connected in a separable manner.

If comprised in this way, since the isolation | separation mechanism becomes a structure which isolate | separates the piping 35 fixed to the vaporization container 3, and the piping 45 fixed to the condenser 4, each piping 35 and 45 is fixed. The vaporized container 3 and the condenser 4 can be separated from each other.

(3) The separation mechanism includes a flange 35a (flange) provided at the end of the pipe 35, a flange 45a (flange) provided at the end of the pipe 45, a flange 35a of the pipe 35, and a flange 45a of the pipe 45. And a clamp 46 that is connected in a state of being joined on the same axis.

With this configuration, the separation mechanism is sandwiched by the clamp 46 in a state where the flange 35a of the pipe 35 fixed to the vaporization vessel 3 and the flange 45a of the pipe 45 fixed to the condenser 4 are coaxially joined. Therefore, the vaporization container 3 can be easily separated from the condenser 4 simply by removing the clamp 46 from the flange.

In this case, by providing a vaporized gas discharge port provided with a flange in the main body of the vaporization vessel 3, the clamp 46 separates the pipe 45 connected to the condenser 4 and the vaporization gas discharge port of the vaporization vessel 3. It is good also as a structure connected so that possible.

As described above, even when the pipe 45 connected to the condenser 4 and the vaporized gas discharge port of the vaporization vessel 3 are directly connected by the clamp 46, the condenser 4 and the vaporization vessel 3 are separated. Can be easily performed.

(5) The vaporization vessel 3 has a bottom wall 3a (bottom wall portion) that is arcuate in cross-sectional view, and the ceramic heater 5 is a heating that has an arcuate placement surface 51 that matches the outer shape of the bottom wall 3a. It was set as the structure which is a member.

With this configuration, the bottom wall 3a of the vaporization vessel 3 is placed in alignment with the placement surface 51 of the ceramic heater 5, so that the heat of the ceramic heater 5 can be efficiently transferred to the vaporization vessel 3.

(6) The bottom wall 3a has an arc shape in which the central portion 3a1 in the longitudinal direction is positioned closer to the ceramic heater 5 than the both side portions 3a2, 3a3 in the longitudinal direction, and the bottom wall is viewed from the ceramic heater 5 side. The peripheral wall 3b (peripheral wall part) surrounding the peripheral edge of 3a over the entire circumference is provided, and the ceramic heater 5 is formed to have a size that contacts at least the entire surface of the bottom wall 3a.

If comprised in this way, since the heat of the ceramic heater 5 will be transmitted to the position used as the center of the curvature radius r of the vaporization container 3, heat will be transmitted to the inside of the waste plastic PL accommodated in the vaporization container 3. The waste plastic PL can be melted in a short time.
Further, since the entire bottom wall 3a of the vaporization vessel 3 is in contact with the ceramic heater 5, the heat of the ceramic heater 5 is transferred to the entire bottom wall 3a of the vaporization vessel 3 so that the vaporization vessel 3 can be efficiently shortened. Can be heated in time.
In particular, the bottom wall 3a of the vaporization container 3 has an arc shape in which the central portion 3a1 in the longitudinal direction (line segment X direction) is located closer to the ceramic heater 5 than the both side portions 3a2 and 3a3 in the longitudinal direction. The melt produced by the melting of the waste plastic PL is always collected on the central portion 3a1 side. Then, even if the collected melt vaporizes in the central portion 3a1 of the bottom wall 3a, new melt is sequentially supplied. Therefore, if at least the region near the central portion 3a1 can be reliably heated, the waste plastic PL is dissolved. And can be surely vaporized.

Therefore, it is not necessary to provide a heating source (heater) up to the peripheral wall 3b surrounding the entire periphery of the bottom wall 3a as in the conventional apparatus for melting the waste plastic PL. It is possible to reduce the size of the apparatus. Furthermore, since the heating range is smaller than the apparatus according to the conventional example, the power consumption necessary for melting and vaporization is sufficiently reduced, so the energy cost required for the treatment of the waste plastic PL is higher than that of the apparatus according to the conventional example. Will be less. Therefore, the miniaturization and the reduction of energy cost make it practical to use the miniaturizing apparatus 1 at home.

Moreover, in the small oil-ized apparatus 1, the case 2 was divided into two spaces S1 and S2 arranged vertically, and the vaporization container 3 and the condenser 4 were accommodated in the spaces S1 and S2. Therefore, the vaporization container 3 can utilize the area of the bottom wall 20a of the case 2 to the maximum, and the area ratio of the bottom wall 3a of the vaporization container 3 to the area of the bottom wall 20a can be increased.
Therefore, since the height of the vaporization container 3 can be lowered by an amount corresponding to the increase in the area of the bottom wall 3a of the vaporization container 3, the height of the small oil vaporizer 1 in a side view can be further reduced. .

Further, in the vaporization container 3, the bottom wall 3a is formed in an arc shape to increase the heat transfer area, and the bottom wall 3a has a flat shape, so that the waste plastic PL charged into the vaporization container 3 is evaporated. The evaporation area increases. As a result, since the liquid depth of the waste plastic PL melted and liquefied becomes shallow at the bottom of the vaporization container 3, it is not necessary to provide a heater for heating up to the upper part of the vaporization container 3 on the peripheral wall 3b.
Therefore, the vaporization container 3 can be configured to be detachably mounted on the mounting surface 51 of the ceramic heater 5, and the waste plastic PL can be disposed only by the ceramic heater 5 provided on the lower side of the bottom wall 3 a. It can be surely vaporized in a short time.
Further, as the evaporation area of the liquefied waste plastic PL is increased, the evaporation amount (evaporation amount) of the vaporized gas PLG is increased, and the oiling processing time can be shortened.

Furthermore, since the bottom wall 3a of the vaporization vessel 3 has an arc shape, the heat transfer area of the bottom wall 3a heated by the ceramic heater 5 can be increased.
For this reason, the area of the bottom wall 3a heated by the predetermined amount of electric power supplied to the ceramic heater 5 is increased, and conversely, the amount of electric power for heating the bottom wall 3a of the predetermined area is decreased (the watt density is reduced). Lower). Therefore, in the vaporization container 3, since the watt density can be suppressed low, it is possible to suppress scorching when melting the waste plastic PL.

Moreover, since the waste plastic melted and liquefied has low thermal conductivity, when the liquid depth of the liquefied waste plastic is deep, it is difficult for heat to be transferred to the waste plastic far from the ceramic heater. Therefore, in order to vaporize the liquefied waste plastic in a short time, the heating temperature of the ceramic heater 5 is increased and the heat of the ceramic heater 5 is transmitted to the waste plastic at a distant position, or the watt density is increased. A method for increasing the thermal coefficient is conceivable. However, in these methods, the liquefied waste plastic may be burnt, and power consumption increases, making it difficult to use at home.
In the small oil making apparatus 1 of the present invention, the bottom wall 3a of the vaporization vessel 3 is arcuate and flat to increase the heat transfer area (evaporation area) of the waste plastic PL. Since the depth becomes shallower and the distance from the ceramic heater 5 to the liquefied waste plastic PL becomes shorter, the heat of the ceramic heater 5 can be quickly transferred to the entire liquefied waste plastic PL, and the waste plastic is vaporized in a short time. be able to.

(7) The ceramic heater 5 is a plate-like member formed of a ceramic material.

If comprised in this way, the shape of the mounting surface 51 of the ceramic heater 5 will be made into the vaporization container by putting the powder of ceramic material into the shaping | molding die of the same shape as the shape of the bottom wall 3a of the vaporization container 3, and sintering. 3 can be easily formed into a shape that matches the shape of the bottom wall 3a.

(8) When viewed from the ceramic heater 5 side (in plan view), the vaporization vessel 3 has a rectangular shape in which the width W2 in the width direction is shorter than the length L2 in the length-width direction. The placed vaporization container 3 was configured to be movable in the width direction while being separated from the condenser 4.

If comprised in this way, while the vaporization container 3 mounted in the ceramic heater 5 is comprised so that a movement in the width direction orthogonal to a curve direction is possible, the vaporization container 3 is mounted in the mounting surface 51 of the ceramic heater 5. FIG. Therefore, the vaporization container 3 separated from the condenser 4 can be easily taken out from the ceramic heater 5.

(9) In the vaporization container 3, a waste plastic PL inlet 32 is provided in a region located in the longitudinal direction perpendicular to the width direction of the peripheral wall 3 b, and a lid member 34 that seals the inlet 32 is provided. It was set as the structure provided in the opening | mouth 32 so that attachment or detachment was possible.

With this configuration, the lid member 34 can prevent the waste plastic PL introduced into the vaporization container 3 from dropping from the insertion port 32.
Further, since the waste plastic PL can be charged into the vaporization container 3 simply by opening the charging port 32 and removing the lid member 34, without removing the vaporization container 3 every time the processing of the waste plastic PL is completed. It becomes possible to process the next waste plastic PL.

(10) The condenser 4 is provided with a storage part 41 in which the refrigerant Wa (cold water) is stored, and the storage part 41, and one end 44a in the longitudinal direction is a gas introduction part 43 of the vaporized gas PLG ( And the other end 44b has a flow pipe 44 having an oil discharge portion 48 (discharge port). The flow pipe 44 is inclined with respect to the horizontal line to discharge the flow inlet. It was set as the structure located above the exit.

In the conventional condenser of the liquefier, the vaporized gas is directly discharged into the refrigerant (cold water) to obtain hydrocarbon oil obtained by condensing (liquefied) the vaporized gas, and the specific gravity is lighter than that of the refrigerant (cold water). In addition, only the hydrocarbon oil floating above the refrigerant was collected.
In such a conventional oil making apparatus, the refrigerant and the hydrocarbon oil are mixed and cannot be completely separated. Therefore, it is necessary to treat the used refrigerant as waste. Therefore, the operation cost of the apparatus is increased by the processing cost of the used refrigerant.

If comprised as mentioned above, the flow path comprised from the some flow pipe 44 and the gas introduction part 43 and the oil discharge part 48 which the one end and the other end of each flow pipe 44 open will be the storage part of the refrigerant | coolant Wa. 41, the vaporized gas PLG is cooled and condensed (liquefied) in each flow pipe 44, so that the hydrocarbon oil POL obtained by the condensation is the refrigerant Wa in the reservoir 41. Will not mix.
Therefore, when the refrigerant Wa is discarded, the refrigerant Wa does not need to be rendered harmless. Therefore, when the refrigerant Wa in the storage unit 41 is replaced, the refrigerant Wa can be thrown away as it is into the sewer, and the disposal cost is unnecessary. Therefore, the operation cost is lower than that of the conventional apparatus.

Further, since the flow pipe 44 provided in the condenser 4 is provided so as to be lowered with respect to the horizontal line from the gas introduction part 43 side toward the oil discharge part 48 side, the vaporized gas PLG is generated. Condensed and refined hydrocarbon oil POL flows along the inclination of the flow pipe 44 toward the oil discharge part 48 side, so that it does not stay in the flow pipe 44 and block the flow pipe 44. .

(11) The condenser 4 has a plurality of flow pipes 44, and the plurality of flow pipes 44 are configured to be spaced from other flow pipes.

With this configuration, the refrigerant Wa (cold water) stored in the condenser 4 enters between the respective flow pipes 44 and the adjacent flow pipes 44, and there is no space between the flow pipes 44. In comparison, each flow pipe 44 can be reliably cooled in a shorter time.

In the above embodiment, the configuration in which the pipe 35 fixed to the vaporization container 3 and the pipe 45 fixed to the condenser 4 are detachably connected by the clamp 46 is exemplified. If it is the structure which can isolate | separate with the container 4, it will not be limited to this aspect.
For example, piping (35, 45) connected to either the vaporization container 3 or the condenser 4 may be directly connected to the connection part of the other condenser 4 or vaporization container 3.

Even if comprised in this way, the vaporization container 3 and the condenser 4 can be isolate | separated, while the vaporization container 3 after an oil-ized process is taken out from the small oil-ized apparatus 1, and the other vaporization container 3 into which the waste plastic PL was thrown in Can be set in the small oil making apparatus 1. Thereby, the liquefaction process of waste plastic can be continuously performed by a batch type.

In the above-described embodiment, the case where the bottom wall 3a of the vaporization container 3 has an arc shape is illustrated, but a flat surface parallel to the bottom wall 20a of the case 2 may be used. In this case, the mounting surface 51 of the ceramic heater 5 also needs to be formed on a flat surface parallel to the bottom wall 20a of the case 2.
Even if comprised in this way, by heating the ceramic heater 5, the heat | fever of the ceramic heater 5 can be transmitted to the bottom wall 3a of the vaporization container 3, and the whole vaporization container 3 can be heated.

Further, in the above-described embodiment, the case where the vaporization container 3 is placed on the placement surface 51 of the ceramic heater 5 is exemplified, but the ceramic heater 5 contacts either the peripheral wall 3b or the top wall 3c of the vaporization container 3. You may make it do.
Even if comprised in this way, since any wall (the peripheral wall 3b, the top wall 3c) of the vaporization container 3 and the ceramic heater 5 contact, the vaporization container 3 is reliably heated by the ceramic heater 5. FIG.

Moreover, in above-described embodiment, the refrigerant | coolant drain pipe 49d was connected to the bottom wall 41a of the storage part 41, and the case where the refrigerant | coolant Wa stored in the storage part 41 was discharged | emitted outside through the refrigerant | coolant drain pipe 49d was illustrated. However, the refrigerant drain pipe 49d may not be provided.
Even in that case, since the upper part of the peripheral wall 41b of the storage part 41 is an opening part 411, the condenser 4 is taken out from the space S2 of the small oil refiner 1, and the refrigerant Wa is discharged from the opening part 411 of the storage part 41. Can be discarded directly.

In the above-described embodiment, the waste plastic PL is charged into the vaporization container 3 by opening the door member 2b of the case 2 and taking out the vaporization container 3, and then removing the waste plastic PL from the charge port 32 of the vaporization container 3. Although the case where it inputs is illustrated, the injection | throwing-in method to the vaporization container 3 of the waste plastic PL is not limited to this aspect.
For example, as shown in FIG. 6 (a), the door 2a of the case 2 is opened, and the waste plastic PL is introduced through the inlet 32 of the vaporization container 3 facing the opening 20b4 after the door 2a is opened. It may be. If comprised in this way, there will be no troublesomeness which takes out the vaporization container 3, and there can exist an effect similar to the above.

In addition, the size of the case 2 of the small-sized oil refiner 1, a line that fits the A4 size based on ISO 216 (international standard), a cross-section obtained by cutting the small-sized oil refiner 1 along the XY plane defined by the line segments X and Y, The cross section obtained by cutting the small oil refiner 1 along the XZ plane defined by the minutes X and Z is sized to fit within the A3 size based on ISO 216 (international standard), so it is easy to carry and general It can also be used on a large desk. Also, it is possible to carry an aircraft into the cabin as baggage.
