Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for incinerating plastic bottles, foam plastic trays, polymeric substances such as paper diapers, activated sludge, mud-like organic substances such as feces, garbage and other wastes.

[0002]

2. Description of the Related Art Conventionally, wastes from general households, hospitals, grocery stores, food processing industries, etc. have been put in a plastic bag and have the municipalities collect or dispose of the wastes. . However, it had to be stored until the garbage was collected. Since the waste is bulky, it requires a large storage space, and it produces a foul odor over time.The waste from the hospital is also dangerous because it contains pathogens and the storage space is limited. There has been proposed an incinerator that heats and dries or incinerates to reduce the external volume and sterilize.

In the above-mentioned conventional waste incinerator, the inside of the deposit is not heated because it is incinerated from the surface of the accumulated waste, and the combustion efficiency is poor. Therefore, the production cost of the device becomes large and the cost is high. Moreover, since the internal structure of the incinerator is complicated, it is difficult to clean the inside of the incinerator.

Therefore, by directly injecting a flame into the accumulated high molecular weight substances, muddy organic substances, and other wastes, the wastes are incinerated efficiently in a steamed state to be carbonized and ash, and small wastes are generated. As a prior invention of the present invention, Japanese Patent Application No. 6- There is a 68884 waste incineration method and incinerator.

[0005]

However, in the incinerator of the invention of the prior application, the fine particles and organic substances in the exhaust gas generated by incineration are separated by the separating device, but the fine particles and organic substances separated in the separating device are separated. Since the substance is accumulated, there is a problem that it is necessary to perform an operation or a cleaning process for removing the separated fine particles or organic substances from the separation device, often during the stop of operation or during the rest. In order to solve the above problems, the incinerator according to the present invention,
We provide an incinerator that has a dust collector integrated with the incinerator to separate fine particles and organic substances in exhaust gas generated by incineration of waste and then removes the separated fine particles and organic substances from the incinerator together with the incinerator. The purpose is to do.

In order to achieve the above object, the incinerator of the present invention comprises an incinerator, which is a main body, of a cylindrical body 1 having side plates at both ends, and the central upper portion of the cylindrical body 1 is provided. Alternatively, a waste input port 2 and a spray device for injecting water into the cylindrical body 1 are provided in the flank, and an outlet for the solidified substance (incinerated matter) that is incinerated and carbonized and ashed in the lower part near the center of the cylindrical body 1. 4 is provided, and a rotary shaft 6 having a stirring blade 7 is provided inside the cylindrical body 1 on the central axis of the cylindrical body 1.

The stirring blades 7 are attached to the rotary shaft 6 so as to be arranged in the left and right directions with blade angles that are inclined in opposite directions with respect to the central portion of the cylindrical body (the central portion of the outlet). Rotating shaft 6
Is rotated by the power transmitted from the drive motor 10.

At the bottom of one side plate 8 of the cylindrical body 1, the cylindrical body 1
A burner 5 for injecting a flame is provided inside the. A collision type dust collector 12 is provided on the upper side of the other side plate 9 side of the cylindrical body 1 with the bottom of the collision type dust collector 12 opened to the inner wall of the cylindrical body 1, and inside the collision type dust collector 12 is a metal plate such as stainless steel or steel or a ceramic. Collision-type dust collectors are formed by arranging mountain-shaped collision plates 13 made of wood or the like at intervals and arranged vertically and horizontally, and arranging a fountain or a spray nozzle 14 for injecting water into exhaust gas under the collision plates 13.
A suction port 11 for exhausting the combustion exhaust gas from the cylindrical body 1 is provided on the upper part of 12. Further, the amount of water ejected from the fountain and the spray nozzle 14 can be appropriately set by the control device 23.

[0009]

The burner 5 of the incinerator constructed as described above
The flame ejected from the cylinder 1 emanates from one side of the cylinder 1 to the other side along the flow of air in the cylinder 1 generated by the suction of the suction pump 17, so that the center of the cylinder 1 serves as the flame path. Become.

Thereupon, the waste that is charged from the charging port 2 and is accumulated or clumped in the cylindrical body 1 is unraveled by the stirring blade 7 and is stirred and the surface of the waste which hits the flame ejected from the burner 5 is hit. While exchanging, while being scooped up by the stirring blade 7 and spreading around the inside of the cylindrical body 1 and falling from the upper part of the cylindrical body 1, the flame is hit and dried and incinerated,
The accumulated wastes and lumps are pyrolyzed by steaming from the inside to be carbonized and ash.

The stirring blades 7 are inclined in directions opposite to each other with the center of the take-out port provided in the substantially central portion of the cylindrical body 1 as a boundary and are rotated.
Since the stirring blade 7 is normally rotated, the waste in the cylindrical body 1 is moved to the center of the cylindrical body 1 by the stirring blade 7, and when the stirring blade 7 is rotated in the reverse direction, the waste is moved to both side plates of the cylindrical body 1. To be Therefore, the waste that spreads at both ends in the cylindrical body 1 is incinerated and carbonized by rotating the stirring blade 7 in the forward direction so as to always move toward the outlet 4 at the center of the cylindrical body 1 while being stirred by the stirring blade 7. And, as it becomes ash, it is scraped up in the outlet 4.

Exhaust gas generated by incineration of waste is sucked by a suction pump 17 and directed toward a collision type dust collector 12 located at an inlet provided in front of the suction port 11, and fine particles and organic substances in the exhaust gas are sprayed by a spray nozzle 14 Fine particles and organic substances that fall in accordance with water droplets that are cooled or increase in gravity and collide with the mountain-shaped collision plate 13 lose the inertial force and fluidity of the fine particles and fall into the cylindrical body 1. Alternatively, the organic substance adheres to the collision plate 13, moves downward along the inclined surface of the collision plate 13, and drops from the lower end of the collision plate 13 to the bottom of the cylindrical body like a drop.

After that, the fine particles and the organic substances that have fallen are scraped together with the incinerated material in the direction of the outlet 4 by the stirring blade 7 and taken out of the incinerator through the outlet 4. Further, when the collision plate 13 is made of a ceramic material, the high temperature exhaust gas passes through the collision type dust collector 12, so that the ceramic of the collision plate 13 becomes high temperature by the exhaust gas and emits far infrared rays, so that the organic substances in the exhaust gas are It is decomposed by far-infrared rays and makes harmful substances harmless.
