Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a refuse incinerator used for treating refuse generated in general households, businesses, etc., and particularly to the structure of its loss.

[0002]

[Prior art]

 All of the conventional incinerators that are commercially available have a flat shape. Therefore, if a large amount of dust or stacks of dust such as newspapers and magazines are charged as incineration objects, most of the air circulation area of the rustle is blocked by the incineration objects, and the combustion air intake As a result of obstructing the supply of air from the plant, combustion efficiency is significantly reduced, causing black smoke and the like. Furthermore, as a result of insufficient supply of combustion air, the debris generated due to incomplete combustion clogs the grate and further deteriorates combustion efficiency.

In order to solve the above problems, for example, a refuse incinerator equipped with an afterburner, a catalyst device, a dust collector, etc. is commercially available, but a refuse incinerator equipped with such an auxiliary device is Naturally, it will be very expensive. The inventor previously applied for Japanese Patent Application No. 06-6549 as a refuse incinerator that has improved this point. That is, this invention identifies the depth length (L) of the primary combustion chamber from the relationship between the maximum charging level (G) of combustible dust and the space (H) on the upper surface of the rostrur, and arranges the multi-sided rostrut. By doing so, it is a device related to a refuse incinerator in which obstacles such as generation of black smoke and incomplete combustion are improved.

However, even if the refuse incinerator with such an improvement is used in practice, it rarely burns depending on the amount or shape of the incineration object to be charged. It was found that the supply of air from the intake air intake is obstructed, which may cause the same problems as before, such as the generation of black smoke and incomplete combustion.

[0005]

[Problems to be solved by the device]

 The present invention completely solves the above-mentioned problems of the conventional technology by a simple means of improving the structure of the multi-sided shape of the waste incinerator without using an expensive and complicated device. The purpose was to provide a waste incinerator that can be used.

[0006]

[Means for Solving the Problems]

 The present invention is a waste incinerator in which a multi-sided grate is arranged, in which a multi-sided grate is provided in which a large number of protrusions are provided on the surface of the multi-sided grate that is in contact with the material to be incinerated and in which the air circulation holes are formed. It is a garbage incinerator characterized by that.

[0007]

[Action]

 In the present invention, the loss incinerator has a multi-sided shape, and the multi-sided shape has multiple projections on the surface that is in contact with the object to be incinerated and has air circulation holes. It is possible to prevent close contact with the fuel cell, and therefore, regardless of the amount of dust to be loaded, the shape, etc., it is possible to always flow the combustion air and secure a sufficient amount of air in each combustion chamber.

Further, the number, size and arrangement of the protrusions to be placed on the surface of the multi-sided roostle to be incinerated and on the surface where the air circulation holes are formed are such as the size of the refuse incinerator. It can be determined as appropriate.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. Here, FIG. 1 is a perspective view of a multifaceted grate according to the present invention, and FIG. 2 is a vertical sectional side view schematically showing a gomi incinerator to which the present invention is applied. Reference numeral 1 denotes a steel furnace body, and inside thereof, a secondary combustion chamber 5 and a secondary combustion chamber 5 and 2 adjacent to the primary combustion chamber 4 and the primary combustion chamber 4 are formed by a channel-type multifaceted rostrur 2 and a partition plate 3. It is divided into the secondary combustion air flow path 6.

The polyhedral rostrur 2 has a channel structure made of steel and is narrower than the width of the primary combustion chamber 4. Further, as can be seen from FIG. 1, a large number of air circulation holes 7 are provided at the corners, and even if a large amount of incinerator is charged at one time, the air circulation holes 7 are not completely closed. That is, even if combustible dust is charged into the upper surface 2a of the multi-sided rostrur 2 and the upper surface circulation hole 7a is blocked, the combustion air can flow from the side surface circulation hole 7b, and the primary combustion chamber 4 The point that the amount of combustion air is sufficiently secured without insufficiency is the most significant difference from the conventional planar shape loss.

In addition, the air intake side of the multi-sided rostrur 2 is integrated with the lid member 8 in which the air intake port 8a is formed, and the opposite side is in close contact with the partition plate 3 as shown in FIG. And is connected to the secondary combustion air passage 6 through the air circulation hole 6a. The multi-sided rod 2 can be pulled out from the furnace body 1 in the direction of the arrow in Fig. 2 via the handle of the lid material 8, the handle 8b, etc., which is convenient for daily maintenance such as removal of residual ash. It

Reference numeral 15 is a protrusion provided on the upper surface 2a of the multifaceted rostrur 2 which is the greatest feature of the present invention and is in contact with the material to be incinerated and in which the air circulation hole 7a is formed. Although twelve protrusions are provided in FIG. 1, the number of protrusions to be installed may be appropriately selected according to the size of the refuse incinerator. The height of the protrusion may be appropriately selected according to the situation, and the mounting method may be any method such as pressing, welding, and bolting. In FIG. 2, 6b is an adjusting plate that regulates the flow rate of the secondary combustion air, 9 is a smoke exhaust flow hole that guides the combustion gas generated in the primary combustion chamber 4 to the secondary combustion chamber 5, and 10 is raw garbage. An incinerator, 11 is a garbage entrance, 11a is a lid for opening and closing the garbage entrance, 12 is a furnace lid, 13 is a combustible garbage entrance that is opened and closed by a revolving door 13a, and 14 is a smoke stack.

In the embodiment shown in FIG. 1, 12 truncated cone-shaped projections made of steel having a height of 3 mm and a diameter of 22 mm are arranged at intervals of 70 mm on the upper surface of the polyhedral rostruls that comes into contact with the material to be incinerated by pressing. It is arranged and manufactured. Next, 12 kg of combustible waste and 1 kg of raw waste were incinerated using the small household waste incinerator of the present invention. The main specifications (example) are as follows.

Furnace size: width 350 mm x height 500 mm x depth 500 mm L (depth of primary combustion chamber): 400 mm H (distance between the upper surface of the multi-sided rostrur and the G level): 220 mm multi-sided rostrul: width 140 mm × Length 400 mm × Height 90 mm, Air circulation hole width 10 mm Raw garbage incineration basket (made of stainless steel): Width 184 mm × Height 130 mm × Depth 234 mm As a result, there is no incineration of garbage and no black smoke is generated, which is high. It was confirmed that the incineration process is possible with the combustion efficiency.

In addition, in the embodiment, the shape of the multi-sided rostr 2 is shown as a channel type, but the present invention is not limited to this, and the air circulation hole 7 is not limited to one surface of the upper surface. Any shape is acceptable as long as it can be provided on two or more surfaces including the side surface that is less likely to be blocked by the combustible dust that is loaded. Further, although each air circulation hole 7 of the multi-sided loss 2 is shown as a single slit-shaped opening extending from the upper surface to the side surface, it may be opened independently on each of the upper surface and the side surface, and the shape is also a slit-shaped opening. It may be a circular hole other than the mouth, a square hole, or the like.

Further, although the example in which the protrusion is provided on the upper surface of the multifaceted rostrur is shown, it may be provided on the side face and the shape of the protrusion may be a continuous linear shape instead of a local shape. .

[0017]

[Effect of device]

 By arranging a multi-sided rostrut with many protrusions on the surface where the incinerator comes into contact and the air circulation hole is formed according to the present invention, black smoke can be completely generated without using an expensive device such as a catalyst. It is possible to provide a refuse incinerator that can be suppressed.
