Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a rotary incinerator for burning hard-to-burn industrial waste containing water and oil such as waste oil and sludge.

[0002]

[Prior art]

 In the conventional rotary incinerator, as shown in FIG. 2, the incinerator A is a single cylinder, the front of which is a drying section A1, the rear is a combustion section A2, and a burner B is provided at the rear of the combustion section A2. It was being done. There are also two-stage rotary incinerators.

[0003]

[Problems to be solved by the device]

 To incinerate waste generated as industrial waste, wood chips and paper chips are easy to burn, but waste oil and sludge are very difficult to incinerate. Since the drying section A1 and the incineration section A2 are conventionally rotated in the same cylinder as described above, the heat of the burner B does not reach the drying zone and becomes excessive or deficient in keeping with the combustion state, so that a stable state is maintained. On the other hand, it was inefficient because the burner installed on the other hand needed to supply and operate more fuel than necessary.

Further, in the conventional two-stage rotary incinerator, drying and burning are performed in the primary combustion furnace, and non-combustible gas is burned in the secondary burning furnace. Since it is done, it is no different from what is done in the same cylinder.

Further, the two-stage rotary incinerator has a large apparatus, is expensive, and is difficult to handle.

From the above point of view, the present invention intends to provide a rotary incinerator capable of efficiently burning wastes such as waste oil and sludge which are difficult to incinerate and which contain water and oil.

[0007]

[Means for Solving the Problems]

 According to the present invention, the incinerator body is divided into a front drying furnace and a rear combustion furnace, with a gap between the outer circumference of the drying furnace and the inner circumference of the combustion furnace, and the rear part of the drying furnace is the front part of the combustion furnace. It is characterized in that the drying furnace and the combustion furnace are rushed into each other and are independently rotatable, and that burners are provided on the drying furnace side and the combustion furnace side, respectively.

Therefore, in the present invention, in the drying furnace, the burner provided on the drying furnace side is used to dry the material to be burned and the initial combustion is performed, and then the combustion furnace is used to perform the combustion by the burner provided on the combustion furnace side.

Since the incinerator is divided into a drying furnace and a combustion furnace, each of which rotates independently and a burner is also provided separately, the drying furnace has a burner according to the burned material. The rotation speed can be selected according to the adjustment and the combustion amount, and the combustion furnace can also adjust the burner and the rotation speed to change the rotation direction depending on the combustion state to maintain the optimum combustion state.

Further, since a gap is provided between the outer periphery of the drying furnace and the inner periphery of the combustion furnace at the connecting portion where the drying furnace has entered the combustion furnace, air is supplied from this gap to promote combustion. be able to.

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a rotary incinerator according to an embodiment of the present invention, in which a main part is longitudinally cut, and FIG. 2 is a front view of a conventional rotary incinerator.

In the rotary incinerator of the present invention, a cylindrical incinerator body 1 is divided into a drying oven 2 at the front and a combustion oven 3 at the back. Support tires 4 and 4'are provided in the front and rear of the outer circumferences of the drying furnace 2 and the combustion furnace 3, respectively, and one of the supporting tires 4 and 4'before and after the drying furnace 2 and the combustion furnace 3 is It is mounted on a passive roller 6 on a support 5 provided below the incinerator body 1.

The other support base 4 ′ is mounted on a drive roller 8 which is rotated by a motor 7 on the support base 5. Then, the rotation of the drive roller 8 causes the drying furnace 2 and the combustion furnace 3 to rotate.

A front hood 10 attached to a frame 9 is provided at the front open end of the drying oven 2, and a loading conveyor 12 that communicates with a burnable material loading hopper 11 inside the drying hood 2 from the front of the front hood 10. A rear burner is inserted, and a burner 13 for drying is provided at the front of the hook front hood 10.

The open end of the rear part of the drying furnace 2 is narrowed, and it projects into the front part of the combustion furnace 3. A gap 14 is provided between the outer periphery of the drying furnace 2 and the inner periphery of the combustion furnace 3 at the rush portion, and air is supplied into the combustion furnace 3 through this gap 14. Further, an intermediate hood 15 attached to the frame 9 is provided at the connecting portion between the drying furnace 2 and the combustion furnace 3.

At the rear open end of the combustion furnace 3, there is provided a pot butt 16 attached to the frame 9, and at the rear of the pot butt 16, a burner 17 for combustion is provided. Further, the upper portion of the hook hood 16 is connected to a duct 19 which communicates with the dust collecting cyclone 18. In the figure, 20 is an ash discharging conveyor provided in the lower part of the shuttle hood 16, 21 is an exhaust cylinder, and 22 is an ash bunker.

[0017]

[Effect of device]

 According to the present invention, the drying furnace and the combustion furnace of the rotary incinerator are separated and rotate separately, so that the number of rotations suitable for drying and combustion can be selected depending on the type and amount of the burned material, and efficient operation can be achieved. it can. In addition, a burner for the drying furnace and a burner for the combustion furnace are provided separately, and by supplying air, it is possible to adjust the heating power suitable for drying and burning depending on the type and amount of the burned material, enabling fuel saving operation, waste oil, It is possible to efficiently burn sludge and other waste that is difficult to incinerate. Further, unlike the conventional two-stage rotary incinerator, the device is compact and the cost is low, and the handling is easy, and it is a useful idea with many effects.
