Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a plastic waste incineration apparatus configured to efficiently incinerate plastic waste.

[Background of the invention]

There have been a wide variety of devices for burning (incinerating) plastic waste, but plastic has the advantage of being a fluid because it easily melts when heated. This melted plastic fluid tends to adhere to the inner wall surface of the casing of the combustion device. The surface of the plastic melt adhering to the inner wall of the casing burns, but the inside is affected by the temperature of the casing and is difficult to burn, making it difficult to completely incinerate the plastic. As the welded plastic adhered to the walls of the case gradually accumulates, it not only becomes difficult to handle, but it also obstructs the supply of sufficient heat energy and air necessary for combustion, thereby achieving the intended purpose. There were problems in that it was difficult to achieve complete combustion and to obtain strong firepower.

[Purpose of the invention]

The present invention has been made by focusing on such conventional problems, and includes a substantially semi-cylindrical inner pot located in the center of a cylindrical outer pot, and plastic waste is sequentially placed in the inner pot. By supplying combustion flame and combustion air from a burner between the outer pot and the inner pot, the plastic waste on the inner pot can be efficiently incinerated. The purpose of this project is to provide an incineration device for

[Embodiments of the invention]

The present invention will be explained in detail below based on embodiments shown in the drawings.

Reference numeral 1 denotes an outer pot formed into a model cylindrical shape, and a fireproof wall 2 made of refractory bricks or the like is constructed on the inner wall surface of this outer pot. A double lid consisting of an inner lid 3 and an outer lid 4 is attached to the front opening 1a of the outer hook 1, and the outer lid 4 is attached to the outer hook 1 by a tightening handle 5. The inner cover 3 is fixed to the inside of the outer cover 4 by means of a fastening handle 6. In addition, the rear opening 1b of the outer pot 1 is a heat exchanger (not shown).
It is formed in an opening that leads to. Reference numeral 7 denotes an inner pot located at the center inside the outer pot 1. This inner pot 7 is formed into a substantially semi-cylindrical shape by cutting a cylinder in the axial direction. The hook 7 is fixed by an inner hook support rod 8 and an inner hook support rod stay 9 so that the central axis of the hook 7 is coaxial with the center axis of the outer hook 1. 10 is a waste input pipe for sequentially supplying plastic waste onto the inner pot 7 from the outside. On the inner surface of approximately 1/4 upper half of the outer pot 1,
A plurality of blower outlets 11 for drawing air toward the inner pot 7 are arranged so as to be sequentially shifted in both the axial direction and the circumferential direction of the outer pot 1. 12
indicates an air supply pipe for blowing out combustion air from the blower outlet 11. In addition, the combustion flame is placed on the inner surface of approximately 1/4 of the lower half of the outer pot 1.
A plurality of heavy oil burners 13 are arranged so as to be sequentially shifted in both the axial direction and the circumferential direction of the outer pot 1.

The above is the configuration of this embodiment.Next, its operation will be described.While the heavy oil burner 13 is combusted, and appropriate air is blown out from the blower outlet 11, air is injected from the waste inlet pipe 10. The plastic waste is fed onto the inner pot 7. As a result, the plastic waste supplied onto the inner pot 7 is burned, but the inner pot 7 receiving the plastic waste is placed in a floating state in the center of the outer pot 1. Moreover, since the structure is such that the entire inner pot 7 is heated to a high temperature by blowing flame and air from a burner over the entire inner pot 7, the plastic waste on the inner pot 7 can be completely burned. This eliminates exhaust pollution and provides powerful combustion power. In addition, this combustion device has an outer pot and an inner pot, and the inner pot is heated to a high temperature, so the heating temperature of the outer pot is relatively low, which reduces the durability of the outer pot. is improved. Furthermore, this combustion device has the advantage of being excellent in practicality because it has a simple structure and can be constructed at low cost.

[Summary of the invention]

As described above, the present invention provides an outer pot 1 formed in a horizontal cylindrical shape, and a floating position at the center of the inner side of the outer pot 1 so as to maintain an appropriate distance between the outer pot 1 and the inner wall surface of the outer pot. a semicircular gutter-like inner pot 7, a burner 13 and a blower outlet 11 for blowing out combustion flame and air from the inner wall surface of the outer pot over substantially the entire length of the inner pot; This is a plastic waste incineration apparatus characterized in that it is equipped with a waste input pipe 10 for supplying waste plastic to a plastic waste incinerator.

〔Effect of the invention〕

Therefore, according to this incinerator, the inner pot 7 that receives the waste can be burned at a high temperature together with the waste, so the waste can be completely combusted, thereby eliminating exhaust pollution. It becomes possible to incinerate plastics. Furthermore, since the heating temperature of the outer pot can be kept relatively low, the durability of the outer pot is improved. Furthermore, since this device has a simple structure, it can be provided at a low cost.
