Abstract

PURPOSE: To remove a residue of thermal decomposition of a waste such as a plastic or rubber waste from a container for the thermal decomposition without interrupting the thermal decomposition and thus improve the operating efficeincy of a waste treatment apparatus by causing the residue to be sucked into a residue-storing room with a depressurizing means including a vacuum pump and then discharging the waste from the apparatus. CONSTITUTION: A waste such as a plastic or rubber waste 3 is thermally decomposed by externally heating a container 2 contg. the waste 3 with a heating means 4. A gas occurring from the thermally decomposed waste in the container 2 is led through a gas channel 15 to a reactor 12 where to be condensed, separated, and recovered. The thermal decomposition leaves a residue in the container 2. The residue is transferred from the container 2 through a residue transfer channel 21 to an externally cooled residue-storing room 20, stored in the room 20 for a while, and then discharged. The residue is sucked and transferred from the container 2 to the room 20 by depressurizing the room 20 by operating a vacuum pump 25 and opening both a valve installed at a channel connecting the pump 25 to the room 20 and a valve installed at the residue channel 21.

[0015]

An embodiment of the present invention will be described with reference to the drawings. (Embodiment 1) In FIGS. 1 and 2, reference numeral 1 is a waste treatment apparatus, and the waste treatment apparatus 1 is, for example, an apparatus for thermally decomposing a waste PET (polyethylene terephthalate) bottle and treating it.

Reference numeral 2 is a container, and the container 2 is a waste 3 to be processed (the waste 3 is a waste PET bottle in this embodiment, but other than the waste PET bottle, for example, waste plastic, waste rubber, etc. Etc.) is to be inserted.

The waste 3 is obtained by crushing, for example, a waste PET bottle into a 3 cm to 5 cm square by a crusher (not shown) and charging it into the charging hopper 31.

Reference numeral 32 is an opening / closing valve for controlling the charging of the waste 3 charged in the charging hopper 31 into the charging machine 33. Further, reference numeral 34 is an opening / closing valve for controlling the feeding of the waste 3 fed into the feeding machine 33 into the container 2.

The container 2 is externally heated by a heating means such as a burner 4 so that the waste 3 in the container 2 is thermally decomposed.

Further, for example, three sensors 5, 6, 7 are provided in the container 2, and the melting amount of the waste 3 in the container 2 is determined by the temperature detected by the sensors 5, 6, 7. Based on the result of the determination, the heating steam controller 8 turns the pump 9 on and off based on the result, and the heating steam described later (the temperature of the heating steam is, for example, about 100 ° C. to about 250 ° C.).
C., more preferably about 150.degree. C.) is controlled. In addition, 10 is a tank for storing water or an aqueous sodium acetate solution.

For example, when the sensors 5 and 6 are at the same temperature (for example, about 300 ° C.), it is judged that the waste 3 is melted up to the position of the sensor 6, and the heated steam or sodium acetate corresponding to it is judged. The steam containing water is supplied into the container 2 by driving the pump 9. In particular, the sensor 7 located above the container 2 is used to detect the gas temperature generated in the container 2.

Further, one end of the steam introducing passage 11 faces the inside of the container 2. The steam introducing passage 11 passes through the inside of a reaction tower 12 which will be described later in the middle, and uses the waste heat generated when the container 2 is heated to heat the water or the sodium acetate aqueous solution supplied by the pump 9 to generate steam. doing. In addition, 13 is an exhaust duct communicating with the combustion chamber 14.

In this way, one end of the water vapor introduction passage 11 is exposed to the inside of the container 2 and is converted into water vapor by the waste P.
Effectively carry out contact reaction with ET bottles and discard PET
This is because the bottle is heated and heated steam is added for hydrolysis to efficiently extract terephthalic anhydride.

On the other hand, the gas thermally decomposed in the container 2 is introduced into the reaction tower 12 through the gas passage 15. This reaction tower 12 is provided with copper, nickel, etc. as a catalyst, and the gas thermally decomposed in the container 2 is passed through the reaction tower 12 to partially condense and reflux so that the carbon number falls within the range of light oil. I am letting you.

The gas passing through the reaction tower 12 is cooled by the condenser 17 through the passage 16. The gas cooled by the condenser 17 becomes a crystalline substance (phthalic anhydride), a liquid (glycol alcohol, phthalic anhydride styrene compound),
It is stored in the storage tank 18. The crystalline phthalic anhydride can be separated through a filter (not shown), and the glycol alcohol and the styrene phthalic anhydride compound can be supplied to the burner 4 as a fuel source. .

The waste 3 is treated in this way,
A residue is generated in the container 2 with the processing. If the residue is left as it is, the residue adheres to the wall of the container 2 and dissipates heat transfer. Therefore, it is necessary to discharge the residue out of the container 2.

If the residue 3'is discharged to the outside of the residue storage chamber 20 as it is, the residue 3'has a high temperature (for example, about 350.degree. C.).
Therefore, the residue 3'cannot be safely treated. Therefore, the outer peripheral portion 20a of the residue storage chamber 20 is cooled by air cooling or water cooling or the like.

As a result, since the thermally decomposed solution is sucked out together with the residue 3 ', the residue 3'is cooled in the residue storage chamber 20 into a block shape and discharged to the outside of the residue storage chamber 20.

Reference numeral 25 is a vacuum pump, 26 is a vacuum pump side passage connecting the vacuum pump 25 and the residue storage chamber 20, and 28 is a first opening / closing means (for example, an opening / closing valve) for opening / closing the residue introducing passage 21. , 29 are second opening / closing means (for example, opening / closing valve) for opening / closing the vacuum pump side passage 26.

Therefore, when the residue 3'in the container 2 is taken out, the residue opening passage 21 is closed by the first opening / closing means 28, for example, manually (or electrically automatically), and the second opening / closing means is opened.

By, for example, manually (or electrically and automatically) opening the residue introduction passage 21 and opening the second opening / closing means 29, for example,
Manually (or automatically electrically) the vacuum pump side passage 26
When is closed, the pressure in the residue storage chamber 20 is lowered, so that the residue 3'in the container 2 is sucked into the residue storage chamber 20 through the residue introduction passage 21 together with the thermally decomposed solution.

26 is opened to operate the vacuum pump 25, and then the residue opening passage 21 is opened by the first opening / closing means 28 and the vacuum pump side passage 26 is closed by the second opening / closing means 29.

As a result, as in the first embodiment, the residue storage chamber
When the pressure inside 20 is reduced and the residue introduction passage 21 is opened by the first opening / closing means 28 in the state where the pressure is reduced, the residue 3 ′ in the container 2 passes through the residue introduction passage 21, The residue 3 ′ of the waste 3 is sucked into the residue storage chamber 20 and can be extracted to the outside of the container 2 without stopping the operation of the waste treatment device 1 as in the first embodiment.

(Third Embodiment) The first and second embodiments described above.
In the above, since the stirring member described later is not provided in the container 2, the residue 3 ′ of the waste 3 adheres to the inner wall of the container 2. When the residue 3 ′ adheres to the inner wall of the container 2, heat transfer is alienated. Therefore, it is necessary to remove the residue 3 ′ adhered to the inner wall of the container 2 and discharge it outside the container 2.
