Moreover, the structure is simplified and the manufacturing cost can be reduced and the equipment can be installed.

Next, the operation of the incinerator device 10 according to the present invention will be described. The incinerator device 10 is installed at a garden of a business office or a general house to incinerate various wastes. Then, dusts or wastes containing plastics are put into the furnace body 44 from the charging port 40 of the furnace body 14 to close the doors 48, 48 of the charging port 40, and the heating port 32. Ignites and burns the incineration object.

In the furnace body 44, air is naturally ventilated to the incineration object from a large number of holes 54 on the outer peripheral surface of the air ventilation pipe 52, and the ignited incineration object continues to burn without misfire. it can. The combustion gas in the furnace body 44 flows toward the communication port 72 at the upper end of the partition wall 12 with the upper canopy 24 as a flow path. At this time, air flows in from the air suction hole 82 communicating with the flow path of the combustion gas in the canopy 24 and the air suction hole 84 of the frame body 44 of the charging port 40.

Further, air flows into the combustion gas flowing from the communication port 72 to the cyclone incineration unit 16 from the left and right air holes 78a and 78b of the air intake unit 76 provided in the vicinity of the communication port 72, and these air flows. In the cyclone furnace body 56, the combustion gas mixed with is secondary-combusted while swirling around the outer periphery of the chimney 58 at high speed, and the combustion gas including unburned gas is completely combusted in the cyclone incinerator 16. And

Further, the dust contained in the combustion gas is centrifugally separated from the combustion gas swirling at high speed in the cyclone furnace body 56, and is dropped and deposited on the inner bottom portion of the cyclone furnace body 56. The completely burned combustion gas goes down in the cyclone furnace body 56, rises in the stack 50 from the lower end of the stack 50 and is exhausted to the outside, and only smokeless and clean combustion gas is discharged to prevent pollution. it can.

Further, since the furnace body 14 and the cyclone incineration unit 16 are constructed of refractory materials such as refractory bricks and castables, they have high heat resistance and can easily incinerate incineration objects having a high combustion temperature such as plastic. It can be processed. Further, since the furnace body 14 and the cyclone incineration unit 16 are integrally formed by being divided by the partition wall 12, the structure is simplified, the manufacturing cost is low, and the facilities from small and medium-sized business establishments to general households can be installed. Meanwhile, pollution such as soot and smoke can be prevented.
