Next, the operating principle of this device will be explained.

The frozen ground 6 contained in the storage tank 4 is fed into the metering tank 12 by the interlocking pump 7.

In the measuring tank 12, when the deep bed 6 is poured into the rotary combustion f15, as shown in FIGS. By adjusting the storage capacity once the storage capacity has been set, it is possible to prevent the deep bed 6 from leaking from the rotating shaft portion 40.

When a predetermined amount of deep bed 6 is fed into the metering tank 12, the metering mechanism 11 senses, and its operation causes the interlocking pump 7 to stop, and then the automatic nozzle valve 13 opens and the frozen ground 6 is poured into the rotary combustion furnace 15. It will be done. Since the combustion flame 41 from the primary burner 17 is constantly blown into the central space 42 of the rotary combustion furnace 15 along the axial direction, the temperature inside the rotary combustion furnace 15 is high, but the temperature inside the rotary combustion furnace 15 is high. By pouring, the temperature inside the furnace decreases at an appropriate rate. By the time the deep bed 6 is poured, the temperature inside the furnace reaches a predetermined temperature...for example, 200'C...
The opening degree of the automatic valve 13 is adjusted so that the temperature inside the furnace reaches a predetermined temperature, and the thermocouple 43 whose sensing portion faces the inside of the furnace is activated. This thermocouple 43 is connected to the automatic valve 13, and the automatic valve 13 closes when the thermocouple 43 operates. At the same time as this automatic valve 13 closes, the interlocking pump 7 that is interlocked with the automatic valve 13 is driven to feed the floor covering 6 into the measuring tank 12 for the next preparation.

On the other hand, the rotary combustion furnace 15 containing the floor door 6 rotates in the direction A in which the blades 29 are opened. With this rotation, the blade 29 lifts up the deep bed 6 and hangs it toward the burning flame 41. The deep bed 6 comes into contact with the combustion flame 41 while being sprayed, and initially the moisture in the frozen ground 6 as well as hydrogen sulfide, methyl mercaptan, methyl sulfide,
Methyl disulfide.

Odorous components such as triethylamine and ammonia.

Sulfur oxides, soot dust, etc. are sent to the deodorizing furnace 31,
When the moisture in the frozen ground 6 disappears, it becomes powder, and this combustible and combustible powder is incinerated in the rotary combustion furnace 15.The combustion of this powder gradually increases the temperature inside the furnace, and near the end of combustion, the temperature inside the furnace reaches about 60℃.
The temperature inside the furnace reaches a high temperature of about 0 to 800 C, and the thermocouple 43 senses this temperature inside the furnace, opens the automatic valve 13, pours the deep bed 6 in the metering tank 12 into the rotary combustion furnace 15, and continues the process in the same manner as described above. Frozen Plains 6 will be incinerated.

If the frozen ground 6 is not passed through the filter 1 and the crusher 2, or if other solid waste is input from the ash outlet 23, if the rotary combustion furnace 15 is rotated in the direction B, the tips of the blades 29 will be removed. 44 can crush lumps in the waste.

On the surfaces of the inner cylinder 19 and blades 29 of the rotary combustion furnace 15,
Heat resistant materials such as alumina and ceramics.

If a corrosion-resistant coating is formed, the inner cylinder 19 and the blades 2
9. Erosion and thermal deformation are suppressed.

As described above, the continuous incineration apparatus for fluid waste according to the present invention includes a storage tank 4 for storing fluid waste, and a measuring tank for weighing the fluid waste sent from the storage tank 4.
12, and the combustion flame 41 extends along the axial direction into the central space 4.
A rotary combustion furnace 15 has a large number of blades 29 protruding from its inner surface to scoop up fluid waste, and a deodorizing furnace burns odor-filled exhaust gas discharged from the rotary combustion furnace 15. A sensing part of a thermocouple 43 that operates at two points, low temperature and high temperature, is placed in the furnace of the rotary combustion furnace 15. There is an automatic valve 13 that opens and closes according to the operation iC of the couple 43, and an interlocking pop 7 that is interlocked with the automatic valve 13 and the metering mechanism 11 of the metering tank 12 in the middle of the transportation vibrator 8a that connects the storage tank 4 and the metering tank 12. After a certain amount of fluid waste sent from the storage tank 4 by the interlocking pump 7 is measured in the measuring tank 12, an automatic valve 13 is opened and the fluid waste is sent to the rotary combustion furnace. 15, the temperature inside the rotary combustion furnace at the start of combustion is sensed by the thermocouple 43, and the automatic valve 13 is closed, and at the same time, the interlocking pump 7 is activated to send the fluid waste into the measuring tank 12, while [Rotary Combustion Furnace] As the rotary combustion furnace rotates, the fluid waste is scooped up by the blades and dispersed toward the combustion flame 41, and the moisture and odorous components in the fluid waste are volatilized, and the odorous components are removed. At the same time, other combustible components in the fluid waste are incinerated in the rotary combustion furnace 15, and the temperature inside the rotary combustion furnace 15 in the latter stage of incineration is detected by the thermocouple 43. The mechanism is such that the automatic valve 13 is opened in order to send the fluid waste in the metering tank 12 to the rotary combustion furnace 15.

Therefore, the fluid waste is scooped up by a large number of blades 29 and dispersed toward the combustion flame 41, so that the waste efficiently contacts the combustion flame 41, vaporizes moisture and odor components, and evaporates combustible components. The ability to incinerate the sexual components is ensured.

Since the furnace is closed, it is possible to maintain a high temperature inside the furnace and increase combustion efficiency, and it is also possible to reduce fuel costs.

Furthermore, rotary combustion furnace 1. ．． Since the odoriferous exhaust gas discharged from the deodorizing furnace 31 is heated to a considerably high temperature by the rotary combustion furnace 15, the deodorizing effect in the deodorizing furnace 31 is extremely high, and the exhaust gas discharged from the deodorizing furnace 31 is odorless. It has various advantages such as, and has extremely high practical value.
