The foreign material collection box for receiving foreign matter to remove the interference of the opening and closing drive of the slider 65, 72 is a cover that is opened and closed to remove the foreign matter accumulated in the foreign matter collection box 70 even during operation of the equipment.

Referring to the method of using the liquid and solid waste pyrolysis apparatus according to an embodiment of the present invention configured as described above are as follows.

As shown in Fig. 1 and Fig. 2, when the above-mentioned first hopper (2) is filled with general and hardly decomposable waste containing a lot of water such as sludge, food waste, livestock waste, etc., the first driving means described above The rotating body 5 is driven by the driven gear 6 fixed to the outer periphery of the driving gear 7 and the rotating body 5 engaged with the bearings 9, 10 and the rotating body 5 for supporting both ends thereof. It is supported by the support pieces 14 and 15 mounted on the frame 18 so as to support the casing which forms the disc type drying chamber 3 which forms the vapor accumulation space 12 outward and is rotated at a predetermined speed.

Therefore, the waste introduced into the rotary disk type drying chamber 3 from the first hopper 2 is guided by the transfer blade 4 formed on the outer periphery of the rotating body 5, and in the left direction (arrow) in FIG. And the waste to be dried while being transported are discharged through the outlet 16. At this time, the transfer blade (4) is formed so that the pitch gradually densified from its inlet to the outlet side of the rotary body (5) outer circumference, continuous input, transfer of waste from the first hopper (2) And drying is smooth.

At this time, the vapor evaporated during the transport of the waste is discharged along the transfer pipe 13 after being accumulated in the steam accumulation space 12 formed by the casing to the outside of the rotary body (5).

In addition, the temperature inside the pyrolysis space 29 of the pyrolysis and drying heat source residence space 55 and the pyrolysis chamber 31 of the first rotary body 5 in which the equipment is operated is the combustion chamber burner 49 described above. Due to the operation of the temperature rises to a predetermined temperature (about 500 ~ 900 ℃), the combustion chamber burner 49 is not yet generated pyrolysis gas from the pyrolysis chamber 31, the temperature inside the combustion chamber 52 to a predetermined temperature The auxiliary fuel 51 is operated until it is heated up. The exhaust gas heated up to a predetermined temperature in the combustion chamber 52 passes through the heat source residence space 55 of the rotary body 5 and the pyrolysis space 29 of the pyrolysis chamber 31 along the transfer pipe 53.

On the other hand, some of the waste discharged from the disk-type drying chamber (3) is recycled, and some are put into the second hopper 19 to which the waste for pyrolysis is introduced along a predetermined transfer device (17). In this case, the thermal decomposition waste may include liquid waste or solid industrial waste as well as dried waste.

Therefore, the waste introduced into the above-mentioned second hopper 19 is the slider 65 of the primary slide gate 21 is the hydraulic (or pneumatic) cylinder 64 by the detection of the waste input detection sensors 62,63. As it is opened by driving (shrinkage driving), waste is put on the secondary slide gate 22, and after the predetermined time elapses, the aforementioned primary slide gate 21 drives the hydraulic (or pneumatic) cylinder 64. It is closed by (kidney drive).

At this time, as the vacuum valve 25 mounted between the first and second slide gates 21 and 22 is opened, the air flowing along the waste is removed during the inflow of the waste, and thus, between the first and second slide gates 21 and 22. The space of is maintained in a low oxygen vacuum state. That is, the air flowing between the primary and secondary slide gates 21 and 22 is introduced into the combustion chamber 52 through the filter 24-the vacuum valve 25-the vacuum tank 26-the vacuum pump 27. do.

Therefore, when the above-described secondary slide gate 22 is opened, and at the same time, as the heat transfer prevention damper 23 is interlocked and opened, the waste from which air is removed is at the inlet side of the pyrolysis chamber 31 having the circular cross section described above. Is put into. At this time, after the secondary slide gate 22 and the heat transfer preventing damper 23 are closed, the pyrolysis gas introduced from the pyrolysis chamber 31 between the primary and secondary slide gates 21 and 22 is a vacuum valve ( 25 is removed as it is opened and supplied to the combustion chamber 52 described above, thereby preventing gas leakage to the outside.

On the other hand, when the above-described primary and secondary slide gates (21, 22) are driven through the sliding groove 78 by the foreign material removal cutter 77 mounted on the inlet side of the slide body 66 slides ( 65) It is possible to remove foreign matter deposited on the surface.

In addition, when the first and second slide gates 21 and 22 are interrupted by the slider 65 due to the foreign matter accumulated between the slider 65 end surface or the sliding groove 78 due to the continuous driving. The clogging of the sliding groove 78 may be prevented by the foreign matter collection box 70 formed at the end of the sliding groove 78. At this time, the cleaning of the foreign matter accumulated in the above-described foreign matter collection box 70 can be performed by opening the cover 72 even during the operation of the equipment.

On the other hand, even when fine foreign matter such as dust is accumulated continuously in the sliding groove 78 described above, the slider 65 is the sliding groove 78 by the slider contact tension device 67 formed on the sliding body 66. Close to the airtight can be maintained. In addition, since the upper and lower surfaces of the slider 65 are crimped and supported by the slider positioning roller 68 provided between the cylinder 64 and the sliding body 66, when the impact is applied to the slider 65 from the outside, or Even when the primary and secondary slide gates 21 and 22 are repaired and replaced, the slider 65 can be kept horizontal.

Accordingly, in the drawing of FIG. 1, the feed vanes 30 spirally formed on the rotating shaft 30a are continuously moved in the right direction (arrow display direction). At this time, due to the variable drive of the drive motor 38 described above, the rotational shaft 30a is variablely driven so that the thermal decomposition speed of the waste can be variably adjusted.

On the other hand, when the temperature inside the pyrolysis chamber 31 is maintained at 500 to 900 ° C., the body and the rotating shaft 30a of the pyrolysis chamber 31 are pyrolysis chambers even when the contraction and expansion are repeated by high temperature heat. (31) The thermal expansion guides 39 and 40 supporting both ends allow the streamlined pyrolysis chamber 31 to always maintain its initial state.

Therefore, the residues thermally decomposed continuously in the atmosphere conditions of high temperature and low oxygen state, as the heat transfer prevention damper 33 formed on the outlet side of the pyrolysis chamber 31 by the detection of the upper and lower opening and closing detection sensors 73 and 74, It passes through the first and second slide gates 34 and 35 and is discharged to the outside.

And mixed with water vapor supplied from 35, supplied to the combustion chamber 52.

At this time, after the pyrolysis gas is completely combusted by the high temperature of 1100 ° C. or higher in the combustion chamber 52, the exhaust gas that has been completely combusted is transferred to the pyrolysis chamber 31 through the transfer pipe 53 and the heat source supply pipe 54 for pyrolysis and drying. The pyrolysis space 29 and the heat source stay space 55 of the rotating body 5 is supplied to stay for a predetermined time, and is discharged through the discharge pipe 56 of the heat source stay space 55 for pyrolysis and drying.

The exhaust gas passing through the discharge pipe 56 described above is heated to the combustion chamber burner 49 by the heat exchanger 57 for heating, and then discharged into the atmosphere through the exhaust fan, and the heat circulation pipe 76 Is supplied to the combustion chamber 52 to promote the temperature increase of the combustion chamber 52.

On the other hand, the air supplied to the combustion chamber burner 49 by the above-described air recovery device is a heat exchanger 59 for cooling the water vapor generated during drying of the waste containing moisture and accumulated in the above-described vapor accumulation space 12. And after passing through the condensation tank 60 to remove moisture, it is heated through the heat exchanger 57 for heating and supplied to the combustion chamber 52 by the blowing fan 50.

At this time, air and gas introduced between the first and second slide gates 34 and 35 when the pyrolyzed residues are discharged, as in the first and second slide gates 21 and 22 at the inlet side of the pyrolysis chamber 31. The filter 42 is supplied to and removed from the combustion chamber 52 by driving the pyrolysis gas mixing fan 44 via the filter 42-the vacuum valve 43-the vacuum tank 26-the vacuum pump 27.
