Embodiments will be described with reference to the drawings. In FIG. 1, 1 is an incinerator and 2 is a cyclone for solid-gas separation. Incinerator 1
And the cyclone communicate with each other through the communication pipe 3, and are tangentially introduced into the cyclone 2 from the upper part of the incinerator 1 through the communication pipe 3, where a centrifugal separation action is provided, the solid matter is at the bottom, and the clean exhaust is at the top. It is discharged into the air from the provided smoke tube 4. Next incinerator 1
The details of each unit will be described in order from. The outermost side of the incinerator 1 is covered with an outer shell 5 made of an iron plate, a furnace wall 6 made of refractory bricks is formed inside the outer shell 5, and an annular air layer 7 exists between them. An injecting port 8 for incineration objects such as dust is provided at a substantially middle portion of the incinerator 1, and a burning and ash removing port 9 is provided at a bottom portion. Reference numeral 10 is a grate provided on the bottom of the furnace.

FIG. 4 is a vertical view of the furnace wall 6, FIG. 5 is a top view of the furnace wall, FIG. 6 is a bottom view of the same, and FIG. 7 is a detailed view of a plurality of air nozzles 11 provided on the furnace wall 6. A large number of air nozzles 11 are regularly and radially arranged on the furnace wall 6 having a circular cross section, so that an annular air layer 7 formed on the outer periphery of the furnace wall 6 is formed.
Combustion air is freshly blown from the air nozzle 11 toward the core. The air layer 7 is provided with a partition wall 19 for partitioning it into upper and lower parts, and partitions it into a lower chamber 7a and an upper chamber 7b. The air nozzle 11 is not limited to the furnace wall 6 and as shown in FIG.
It is installed vertically upward on the bottom of the furnace, and combustion air is blown up from here. The air nozzle 11 has a nozzle hole 11a at its tip (FIG. 7).

8 to 10 show a combustion air supply system.
As is clear from FIG. 9, a blower 12 is installed below the space between the incinerator 1 and the cyclone 2. The operation of the blower 12 is controlled by the control panel 13. Well blower 12
The air sent from is sent to the vertical pipe 14 (square pipe in the figure).
The vertical pipe 14 branches into a lower branch pipe 15a, a middle branch pipe 15b and an upper branch pipe 15c, and a volume damper 16 (16
a, 16b, 16c) to the annular air layer 7. After that, it is blown from the nozzle 11 toward the core.
(Figure 10). The annular air layer 7 is placed in the upper chamber by a partition plate 19.
Partitioned into 7a and lower chamber 7b, the upper branch pipe 15c leads to the upper chamber 7b, and the middle branch pipe 15b leads to the lower chamber 7a. The lower branch pipe 15a communicates with the bottom of the furnace.

FIG. 11 shows details of the exhaust smoke pipe 4 at the top of the cyclone. The smoke pipe 4 has a cylindrical shape, and a net cylinder 17 is attached to the top thereof, whereby fine particles are completely removed and exhausted. Reference numeral 18 is a measurement hole provided in the lower portion of the smoke pipe 4, from which an exhaust sample is sampled and used for measurement.

[0009]

Function: A material to be burned (however, a synthetic resin product is selectively removed and charged) is charged from the charging port 8 and stored on the bottom grate 10. Then, ignition is performed at the lower firing port / ash outlet 9.
At the same time, the blower 12 is rotated to send air to the vertical pipe 14.
Air is sent from the lower branch pipe 15a to the furnace bottom, from the middle branch pipe 15b to the lower chamber 7a, and further to the upper chamber 7b via the upper branch pipe 15c. The air sent to the lower chamber 7a of the annular air layer 7 is blown from this through the nozzle 11 toward the core. Further, the air sent to the upper chamber 7b is blown out from here toward the core through the nozzle 11 as well. Thus, not only the upper and lower sides of the furnace, but also the entire circumference of the furnace are evenly supplied to completely burn the material to be burned, and the flue gas is tangentially sent from the upper part to the cyclone 2 through the communication pipe 3. At this time, the speed adjusting air is supplied by opening and closing the adjusting hole 3a provided in the middle of the communication pipe 3, and is sent into the cyclone 2 at an appropriate wind speed to be subjected to the centrifugal action.
The exhaust gas that has been solid-gas separated in the cyclone 2 rises in the exhaust pipe 4, removes the fine particles remaining in the net cylinder 17 at the top, and is exhausted to the atmosphere.

[Effect] Consists of an incinerator 1 having a charging port 8 in the upper part and a firing port / ash outlet 9 in the lower part, a cyclone 2 connected by a communication pipe 3 in the upper part, and an exhaust pipe 4 connected to the upper part of the cyclone 2. The incinerator 1 comprises an outer shell 5, a furnace wall 6 made of refractory bricks provided with an outer layer 5 and an annular air layer 7 vertically divided by a partition plate 19. Lower part of the air layer 7 having a large number of air nozzles 11 facing the core
Air is sent from the blower 12 to the 7a, the upper chamber 7b, and the furnace bottom, and the air is sent from the air nozzle 11 to the upper and middle parts of the incinerator and the furnace bottom, and the air is sent to the lower chamber 7a, the upper chamber 7b, and the furnace bottom. Volume dampers 16a, 16b, and 16c are provided in the middle branch pipe 15b, the upper branch pipe 17c, and the lower branch pipe 17a, respectively, so that the air supply can be controlled individually. With such a configuration, the combustion air is supplied throughout the incinerator, and incomplete combustion due to insufficient air does not exist at all, and ideal combustion is possible. Since such combustion is good and solid-gas separation is performed well in the next cyclone, it is possible to provide an incinerator free from pollution due to soot and the like even in the vicinity of a house. Further, since the connecting portion is provided with the hole 3a, the wind speed can be adjusted by opening and closing the hole, and the efficiency of the solid-gas separation portion can be further increased.
