Description

[Detailed explanation of the idea] Industrial applications The present invention relates to incineration equipment.

BACKGROUND ART Conventionally, in incineration equipment in which combustion is performed in a rotary kiln and then post-combusted in a grate furnace, the incinerated material from the rotary kiln is directly dropped onto the grate from the kiln body of the rotary kiln.

Problems to be Solved by the Invention According to the above conventional configuration, since the kiln main body rotates in a fixed direction, the incinerated material, that is, the waste from the kiln main body, is always concentrated in one place on the grate, and in uneven places. There was a problem that because the fuel fell, it was not evenly distributed on the grate, making combustion unstable.

Therefore, the purpose of the present invention is to propose an incineration facility that can solve the above problems.

Means for Solving the Problems In order to solve the above problems, the incineration equipment of the present invention combines the rotary kiln and the grate furnace in an incinerator that performs combustion in the rotary kiln and then post-combustion in the grate furnace. A guide cylinder for guiding the incinerated material is provided at the connection part of the rotary kiln, which can rotate forward and backward around the same rotation axis as the rotary kiln.

Effect In the above configuration, during the incineration of waste, the guide tube rotates forward and backward alternately for a certain period of time, and the incinerated material from the rotary kiln side is evenly distributed and falls onto the grate on the grate furnace side. be done.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 1 is a waste incineration facility, which includes a rotary kiln 2 for burning waste, a grate furnace 4 for post-combusting the incinerated material, that is, exhaust 3 from the rotary kiln 2, and a grate furnace 4 for after-burning the waste 3 from the rotary kiln 2. It is composed of a guide tube 5 that is uniformly distributed on the grate furnace 4 side. The guide cylinder 5 is rotatably supported on the same rotation axis as the kiln main body 6 of the rotary kiln 2 via, for example, a receiving roller (not shown), and one end thereof is connected to the discharge port end 6a of the kiln main body 6. The other end is positioned above the end of the grate 7 of the grate furnace 4. Further, the guide tube 5 is rotatable in forward and reverse directions by a rotary drive device (not shown, but for example, an electric motor). Furthermore, the grate 7 is arranged to have an optimum head H based on the angle of repose of the discharged material 3 from the rotary kiln 2 side, and of course the central axes of the rotary kiln 2 and the grate 7 coincide in a plane. It's like that. 8 and 9 are the furnace walls on the side of the grate furnace 4. Note that air seals are provided in the gaps between the kiln body 6 and the guide tube 5 and the gaps between the guide tube 5 and the furnace walls 8 and 9.

In the above configuration, during the incineration of waste, the guide tube 5 is also rotated in forward and reverse directions for a certain period of time as shown by arrows A and B. Therefore, the discharged material 3 from the kiln main body 6 is transferred to the grate 7 by the rotating guide cylinder 5.
A fixed amount is alternately dropped on the left and right positions above (indicated by 3A, 3), resulting in a dispersed state on the grate 7. Therefore, the entire fire grate 7 can be used effectively and a stable combustion state can be obtained.

Effects of the invention According to the above-mentioned configuration of the invention, a guide tube for guiding incineration, which can freely rotate in forward and reverse directions around the same rotation axis as the rotary kiln, is provided at the connection part between the rotary kiln and the grate furnace. By rotating the rotary kiln forward and backward for a certain period of time, the incinerated material from the rotary kiln side can be evenly distributed and dropped to the left and right positions on the grate on the grate furnace side, thereby achieving stable combustion. I can do it.
