DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. The incinerator 100 of the present invention includes a horizontally arranged cylindrical incinerator body 1, a cooling tank T installed above the incinerator body 1 and containing cooling water for covering the upper portion of the furnace body 1, and a furnace body. Chimney C standing upright in the center of 1
And four legs L provided on the lower side of the furnace body 1.

The incinerator body 1 is made of heat-resistant metal and has a horizontal semi-cylindrical bottom 11, a side wall 12 with both ends of the bottom 11 extended upward, and a horizontal cylindrical ceiling 13. Front wall 14 that covers the cylindrical body and the front and back surfaces thereof
And a body 10 including a rear wall 15. Front wall 1
Said bottom 11 and side wall 1 including 4 and rear wall 15.
The inner wall of 2 is covered with refractory bricks R, and the ceiling 1
3 The outer wall is in contact with the cooling water in the cooling tank T.

Inside the incinerator body 1, a partition wall 2 made of refractory bricks is provided slightly rearward from the middle, and the front part thereof serves as the primary combustion chamber 1A of the incinerated material. The rear portion of the partition wall 2 is further divided into upper and lower parts by a secondary combustion cylinder 3 fitted between the partition wall 2 and the rear wall 15, and the lower part thereof is a dust storage chamber 1B. Partition wall 2 between primary combustion chamber 1A and dust storage chamber 1B
Are communicated with each other through an opening 21 provided in the. The secondary combustion tube 3 is formed by fitting a pipe-shaped object in which a cylindrical surface-shaped bottom plate 31 having a small radius of curvature and a cylindrical surface-shaped top plate 32 having a large curvature radius are stacked in a direction intersecting the axis of the furnace body 1. The left end is opened to form a communication port 33 with the dust storage chamber 1B. A round hole provided near the right end of the top plate 32 serves as a communication port 34 with the upper space 1C.

At the upper part of the incinerator body 1, an upper partition plate 4 having a circular arc-shaped cross section which bulges downward is partitioned from the primary combustion chamber 1A and the upper space 1C of the secondary combustion tube 3 to form a tertiary combustion chamber 1D. Is becoming The tertiary combustion chamber 1D communicates with the upper space 1C at an opening provided at the rear end, and communicates with the chimney C erected on the upper surface of the body 10 at a front portion thereof located in the middle of the primary combustion chamber 1A. is doing. Body 1
The front wall 14 of No. 0 is provided with a door inlet 16 for charging incineration, and the rear wall 15 is provided with a door outlet 17 for taking out dust.

In the primary combustion chamber 1A, a cylindrical lattice (perforated plate) 5 that bulges upward is installed axially on a cylindrical bottom face 18. Further, on both outer sides of the lattice 5, blower pipes 6 in each of which fumes 61 are arranged are provided along the lattice 5. In this embodiment, the lattice 5 is made of a heat-resistant metal, and is formed by combining a large number of arc-shaped weft members 51 and straight rod-shaped warp members 52, as shown in FIG. Blower tube 6
Is connected to a blower (not shown) via an extension pipe 62 extended to the lower side of the incinerator body 1. Further, in the primary combustion chamber 1A, in front of the partition wall 2, a smoke shield plate (incinerator holding plate) 22 is provided upright while maintaining a predetermined distance from the opening 21 and having an upper end higher than at least the opening 21. This smoke shield 2
Reference numeral 2 prevents the incinerated matter in the primary combustion chamber 1A before or during combustion from entering the dust chamber 1B together with the exhaust flow (smoke). The smoke shield 22 may be a flat plate, but the opening 2
The use of the cylindrical face plate convex toward 1 is effective for holding the incinerated material and has an advantage of repelling the burner flame and promoting ignition when the burner for ignition is blown from the charging port 16.

Next, the operation of the incinerator 100 will be described. The incineration material is charged into the primary combustion chamber 1A from the charging port 16 above the lattice 5. After depositing a certain amount of incineration,
Ignition is made from the charging port 16. This ignition may be performed by an ignition means such as a burner installed in the primary combustion chamber 1A.
When air is blown out from the blower pipe 6 at the same time, combustion burns in a layered manner in almost the entire region close to the lattice 5, and the plastics are melted and burn while dropping below the lattice 5,
Other solids fall below the grate 5 after combustion. As a result, the incineration material deposited in the primary combustion chamber 1A gradually moves downward due to the reduction in bulk due to combustion, and is incinerated sequentially. That is, the incinerated material in the vicinity of the grid 5 burns most quickly, and the incinerated material in the upper part sequentially descends to the position of the grid 5, and all the incinerated material can be burned smoothly and quickly.

Particularly, since the blower pipes 6 in which the fumaroles 61 are arranged on both sides of the lattice 5 are arranged, the air gently flows toward the inside of the lattice 5, and the smooth and quick combustion near the lattice 5 is performed. Can last. Further, since unburned gas and dust are contained in the exhaust gas flowing from the primary combustion chamber 1A through the opening 21 of the partition wall to the dust storage chamber 1B, the dust is temporarily retained in the dust storage chamber 1B to drop the dust. Further, the unburned gas containing the toxic gas is incinerated in either or both of the burner B1 blown into the secondary combustion cylinder 3 and the burner B2 blown into the tertiary combustion chamber 1D. Normally, only the burner B1 is heated to incinerate unburned components in the exhaust gas, but when further heating is required, the burner B2 is also used to improve the cleanliness of the exhaust gas.

In the above-mentioned embodiment, the porous partition may have a structure having a large number of openings such as a wire mesh, a punching metal, a crosspiece, etc. for communicating the upper and lower sides or the outer and inner sides of the partition in addition to the lattice 5. Further, the refractory bricks R and the cooling tank T are for improving durability, and have an effect of extending the life of the refractory metal furnace body 1 by about ten times.
