Description of the Invention (/) [Background of the Invention] The present invention relates to a recovery device for obtaining oil from waste plastics. The conventional device obtains heavy oil (fuel oil A equivalent) from the waste plastic (high polymer permanent waste) after decomposing with tritium. Such conventional devices are relatively low in the melting tank, about 250. 〇 [or 70 ° C for polyvinyl chloride] melting solid waste plastics (such as polyethylene, polystyrene and polyvinyl chloride) at a temperature of about 40 Ot: (or for polyvinyl chloride) It is i 7 0t) to thermally decompose the molten waste plastic in a thermal decomposition tank, and cool the gas generated by the thermal decomposition to obtain heavy oil. If solid waste plastic is fed directly into the pyrolysis tank, the waste plastic will be carbonized. Such carbonization not only reduces the recovery efficiency, but the carbonized products are not easily removed. This is why a melting tank is first installed to melt solid waste plastic. However, the traditional device of the type just mentioned involves the following problems. First, the need to use a melting tank in addition to the thermal decomposition tank makes the entire assembly more complicated, larger, more expensive, and difficult to maintain. The second 'takes longer to process waste plastic, thus reducing the yield of heavy oil and increasing production costs. The present invention can solve the problems of the above-mentioned conventional technology. The object of the present invention is to provide a simple and compact oil recovery device from waste plastic, which can provide substantial cost savers and ease of maintenance while providing higher yields and lower Great economy. 3 (Please read the precautions on the reverse side before filling out this page) ,!

Description of Invention (j) [Detailed Description of Invention] 1 and FIG. 6 show an embodiment proposed to solve the problem of the conventional device described above. The embodiment shown in FIG. 1 includes a tank 3 closed from the outside, which has front and rear air channels 8, multiple heating pipes 4a, 4 b, 4 c · 4 d, 4 e and 4 ί, which are arranged in a front communication space C Between a partition 7 (4 a and 4b), a rear communication space between Cr and partition 7 (4e and 4f), and a front and rear communication space between Cf and Cr (4c and 4d); -A hot air generator 21, which is connected to a heating pipe located between the front communication space C f and the partition plate 7; and a flue pipe, which is guided to the outside air gardener and is connected to the rear side The heating pipe (4e and 4ί) between the communication space Cr and the partition 7. On the other hand, the embodiment shown in Fig. 6 has multiple heating pipes 4a, 4k, 4 (:, 4 < 1,4 € And 4 £, they are all benders and communicate with the hot air generator, the melting chamber and the flue pipe in the stated order. The configuration shown in Figs. 1 and 6 can keep the heating tube in the thermal decomposition chamber at a temperature suitable for thermal decomposition, and keep the person in the melting chamber at a temperature suitable for melting, and keep the person in the communication space at the above two temperatures. Temperature between people. The solid waste plastic P supplied to the melting chamber R r is heated and melted by the heating pipes 4 f, 4 e, 4 c and 4 d kept at a relatively low temperature. The molten waste plastic L reaches the thermal decomposition chamber Rf through the communication space Rc. As the amount of molten waste plastic L increases, its top level will rise to a higher part of the thermal decomposition chamber R ί. We arrive at the higher R f located in the thermal decomposition chamber _5_ This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) (Please read the precautions on the back before filling this page) _. Take · Order 520391 Printed by the Ministry of Standards and Standards Bureau Consumer Consumption Cooperative Association ^ Α7 Β7 V. In the description of the invention (ψ), the molten waste plastic L of the heating tube 4 a maintained at a relatively high temperature is heated and thermally decomposed. Its gasification. The gasified cracked gas is cooled to liquefy and becomes heavy oil (fuel oil A equivalent). The combination of a thermal decomposition tank and a melting tank contributes to the overall simplification and size reduction of the device, and achieves substantial cost savings and ease of maintenance, while providing higher productivity and greater economics in heavy oil production. In FIG. 1, the groove body 3 has a tapered front end 3f and converges toward the bottom. Converging the bottom reduces the amount of heat required to maintain the temperature of the molten waste plastic L from the bottom when the device is stopped. When the device resumes operation, after the molten waste plastic L moves through the communication space R c to the thermal decomposition chamber R f, the molten waste plastic L is melted because its specific gravity becomes lower and lower as it transitions from the molten state to the thermally decomposed state. Waste plastic L rises. So the 'convergent bottom' can be used for rising molten waste plastic to expand. The slot in the embodiment shown in Fig. 6 has an upright front end 3? And does not converge toward the bottom. However, of course, its groove can be designed similar to that shown in FIG. Having said that, the above designs are not necessary elements of the present invention. Embodiment The embodiment shown in Fig. 1 will be described with reference to Figs. In the drawing, the reference numeral 2 indicates ~ a thermal decomposition tank, which constitutes a main part of the oil recovery device 1. The thermal decomposition tank 2 includes a tank body 3 which in turn includes a front end 3 f ′, a rear end 3 r and a bottom 3 d, as shown in FIGS. 1 and 2. A partition 7 is installed between the left side 3 P and the right side 3 q in the center of the groove 3 7 _ _____6___ This paper size applies to the Chinese National Standard (CNS) A4 specification (21 〇χ 297 mm) (Please read the precautions on the back before filling This page) Order 520391 Α7 Β7 V. Description of the invention (γ). The partition plate 7 has a closed hollow structure. The interior of the partition is partitioned by a partition wall 9 into a front space S f and a rear space S r. In this way, a thermal decomposition chamber R f and a melting chamber R Γ are formed in front of and behind the partition plate 7, respectively, and a communication space Rc is formed under the partition plate 7 at the same time. The outer bottom of the groove body 3 is covered with an outer plate 14, so a closed heat-maintaining space is formed between the outer plate 4 and the groove body 3. The heat-maintaining oil W is supplied into the heat-maintaining space 32 from a heating device 31 described later. In the first embodiment shown in FIG. 1, an outer cover 13 covers the groove body 3 and the outer plate 14, and a front-end communication space C f and a rear-end communication space C r are provided. The front-end communication space C f is between the oblique cone front-end 3 5 of the tank 3 and the jacket 1 3, and the rear-end communication space C r is between the rear-end 3 r of the tank 3 and the jacket 1 3 between. Four horizontally spaced heating pipes 4 a are installed in the upper part of the thermal heating chamber R f.

Description of the invention (b) The rear space S r to the partition 7 and their rear openings lead to the jacket 1 3 external. A lower group of four horizontally separated pipe fittings 4 e are similarly arranged in the melting chamber R ′, and the front (internal) openings of the heating pipes communicate with the rear space S r in the partition 7 and their The rear opening leads to the rear groove® space C r. The heating pipes 4 a, 4 b, 4 c, 4 d, 4 e and 4 f are individually separated at intervals of 10 to 15 cm. This configuration forms a continuous air passage 8 from the heating tube 4 a through the front space S f, the heating tube 4 b, the front communication space cf, the heating tube 4 c and 4 d, the rear communication space C r, and the heating tube 4 e. With the rear space C r to the heating pipe 4 f. In Fig. 1, the uppermost heating pipes 4a and 4f in the thermal decomposition chamber and the melting chamber are connected to the hot-chamber gas generator 21 and the smoke duct 22. However, the pipe fittings of the type just described are not absolutely necessary for the present invention. As long as the other types of pipe fittings can properly maintain the thermal decomposition chamber, the temperature in the melting chamber and the communication space is sufficient. A hopper 12 for feeding solid waste plastic P is installed at the uppermost end of the melting chamber. The reference numeral 15 indicates a cover for covering the top of the tank 3, and a pipe 16 is arranged at the highest point of the center to collect the cracked gas. The duct 16 is connected to a scrubber 52 which will be described later. The outer opening of the uppermost heating pipe 4a is connected to a hot air generator, and the outer opening of the heating pipe 4f is connected to a flue pipe 22 having a blower 2 3. In this way, the hot air supplied from the hot air generator 21 is discharged to the outside through the flue pipe 22. The heating pipe 4a in the upper end of the thermal decomposition chamber R ί has a temperature ratio higher than that in the melting chamber R r (please read the precautions on the back before filling this page).

Description of the invention (7) The heat pipes 4d, 4c, 4e and 4ί are relatively high in temperature. Since the hot air radon loses its heat in moving through the air passage 8, the heating pipe 4f at the downstream has a lower temperature than the heating pipe 4a at the upstream. To sum up, the diameters of the "length" number and the spacing and other conditions of the individual heating pipes 4a, 4b, 4c, 4d, 4e and 4f are determined to make the lower heating pipes 4c and 4d have a temperature Both become high (usually 250 ° C, or 70 ° C for polyvinyl chloride) enough to melt the waste plastic P, while the temperature of the uppermost heating tube 4 a is sufficiently high (usually 4 0 0 ° C, or 170 ° C for polyvinyl chloride) The temperature at which the molten waste plastic L is thermally decomposed. The thermal decomposition chamber requires not only high temperature but also large heat. Therefore, the heating pipes 4a and 4b in the thermal decomposition chamber may be designed to have larger diameters than the heating pipes 4c, 4d, 4e, and 4f. In addition, the heating pipes 4a and 4b in the pyrolysis chamber may be zigzags to increase the contact area with the surroundings. The outer surface of the heating pipe 4 a and the inner surface of the tank body 3 and the place where the molten waste plastic L and the cracked gas are in contact are coated with a heat-resistant liquid glass (which becomes a solid at the room temperature), made of steel or other metal The completed heating pipe 4a and the tank body 3 are susceptible to the corrosive effect of the oxidation accompanying heating. Especially when the waste plastic is polyvinyl chloride, the chlorine generated by thermal decomposition will quickly corrode and oxidize the metal.

Description of the invention (j) First, the hot air generator 21 supplies hot air Η to the uppermost heating pipe 4a, as indicated by the arrow in FIG. 1, so it is heated to about 4 0 ° C. (Or 170 ° C for polyvinyl chloride). The lower heating tubes 4 c and 4 d are heated to approximately 250 ° C (or 7 CTC for polyvinyl chloride). The hot air passing through the air passage 8 is then discharged to the outside through the flue pipe 22 with the help of the suction effect provided by the blower 2 3. Solid waste plastic P (such as polyethylene, polystyrene, and polyvinyl chloride) is fed into the hopper 12. The pulverizer 51 breaks the larger pieces into smaller ones. The solid waste plastic P that has been poured into the hopper 12 is supplied to the inside of the melting chamber Rf. In the tank 2, the waste plastic P will fall to its bottom, where it will be heated and melted by the heating pipes 4c and 4d maintained at a relatively low temperature. The melted plastic waste enters the thermal decomposition chamber R f through the groove ® space R c and is stored in the tank 3, and its surface will rise as the storage capacity increases. When the rising top surface reaches the heating pipe 4a which is kept high in the upper part of the thermal decomposition chamber Rf, the molten waste plastic 1 heated by the heating pipe 4a is thermally decomposed and gasified. The cracked gas thus generated passes through the conduit 16 to the scrubbing tube 52, where the chlorine gas contained in the cracked gas is neutralized. The cracked gas is then supplied from the scrubber to the condenser 54, where it is cooled and liquefied to a heavy oil (fuel oil A equivalent). The condenser 54 is often cooled with a cooling liquid supplied from the cooler 55. The obtained heavy oil is supplied to an oil-water separation tank to remove moisture from the heavy oil. Filter 5 8 removes impurities from heavy oil. The heavy oil thus obtained is stored in a storage tank 59.
