Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator capable of incinerating various garbage, and more particularly to an incinerator having a function as a boiler.

[0002]

2. Description of the Related Art Generally, an incinerator is provided with an incinerator for incinerating various garbage, and a waste chimney for discharging gas burned in the incinerator. A cyclone structure is used so that it can be smokeless, odorless, and dustless. Further, in order to perform sufficient combustion in the combustion chamber so that black smoke is less likely to be generated, ventilation means is provided, for example, as disclosed in Japanese Patent Application Laid-Open No. 9-72523. The ventilation means disclosed in this publication has a structure in which a plurality of blower pipes are arranged in a combustion chamber (primary combustion chamber) so that swirls in two directions with different angles are generated. A secondary combustion chamber is provided so that the unburned gas can be completely incinerated.

Further, since the main body of an incinerator is generally made of metal such as iron, the inner surface of the incinerator is lined with refractory bricks in consideration of durability and heat resistance. A member is provided.

[0004]

In the conventional incinerators including the above-mentioned known techniques, since the air supply to the incinerator is not sufficient, the combustion temperature is low, and black smoke and odor are easily generated. There is. Further, as described above, it is possible to complete combustion by providing a plurality of combustion chambers, but the structure becomes complicated and the cost becomes high.

Further, if the combustion temperature in the incinerator is increased, the lining member will be severely deteriorated, and the maintenance will be difficult.
The main body is thermally deformed, which causes problems such as inability to open and close the incinerator door.

The present invention has been made on the basis of the above-mentioned problems, and it is possible to burn at a high temperature and to provide a simple structure and durability without providing a lining member such as refractory brick in the incinerator. The purpose is to provide an excellent incinerator.

[0007]

In order to achieve the above object, the incinerator according to the present invention is arranged so as to surround the incinerator in which various garbage are incinerated, and the incinerator. A main body having a double structure including a tank for storing water, an opening / closing door provided in the main body for allowing various garbage to be put into the incinerator, and an opening having a large number of openings on the inner surface of the incinerator. And an air supply passage that allows the air to be supplied into the combustion chamber through the inside of the tank, and a blower installed in the main body so as to send the air to the air supply passage. .

According to the above construction, since the incinerator has a double structure, that is, the incinerator has a water cooling structure, it is not necessary to attach a lining member such as refractory brick to the inner surface thereof. Moreover, since a large amount of air is sent into the incineration chamber from the inner wall around the incineration chamber, it is possible to incinerate at a high temperature.

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention will be specifically described below with reference to FIGS. In these figures, FIG. 1 is a perspective view showing the overall structure of the incinerator, FIG. 2 is its front view, FIG. 3 is its plan view, FIG. 4 is its right side surface, and FIG. 5 is its sectional view. is there.

The main body 1 of the incinerator has a double structure including an incinerator chamber 2a and a tank 2b provided so as to surround the incinerator chamber 2a and containing water. The combustion chamber 2a is not particularly limited, but in the present embodiment, it is formed as a space having a substantially cubic shape, and the front surface portion thereof, that is, the front surface of the main body 1, is provided with an insertion door 3a at an upper portion. The ash outlet doors 3b are attached to the lower portions so as to be opened and closed.

An exhaust chamber 5 having a cyclone structure is provided on the rear side of the incineration chamber 2a, and the exhaust chamber 5 is provided with a chimney 5a so as to communicate with the exhaust chamber 5 upward. A cyclone ash storage chamber 5b is provided below. The tank 2b has an exhaust chamber 5,
Also, a part of the chimney 5a is integrally formed.

A water stop tank 7 is provided in the main body 1 so that the water level in the tank 2b is always constant.
It can supply water. Also, in the main body 1,
A circulation supply pipe 12a is connected to the bottom of the tank 2b so that the water in the tank 2b can be circulated to an external device, and a circulation discharge pipe 12b is connected to the top of the tank 2b. Drain pipe 12c for draining water in 2b
Is provided. Further, a steam pipe 15 is provided in the main body 1 so as to communicate with the tank 2b so as to be adjacent to the chimney 5a.

A large number of openings 20 for supplying air into the incineration chamber are formed in the inner wall defining the incineration chamber 2a. In the present embodiment, this opening 20 is
It is provided on the side wall and the lower surface wall other than the portion where the input door 3a and the ash outlet door 3b are provided, and a large amount of air can be sent to the incinerator 2a from various directions.

As shown in FIG. 5, a large number (6 × 4) of openings 20 are formed in each of the side walls and the bottom wall in the vertical direction and the horizontal direction, so that the entire incinerator can be formed. Air is sent in. Each opening 20
Is connected to an air supply pipe 21 that is formed to bulge along the outer surface of the main body 1, and the air supply pipe 21 and each opening 2
0 is communicated with 0 via a connecting pipe 21a passing through the inside of the tank 2b. A blower 25 connected to a part of the air supply pipe 21 is installed in the main body 1. By sending air to this part, air is released from each opening 20. There is.

In the incineration chamber 2a, a frame (separation grid) 30 may be arranged so as to separate the incineration section and the ashing section (see FIG. 3). Also, an ignition burner 3 is attached to the main body 1.
2 may be installed. Further, it is preferable to separately install an oil tank 37 connected to the main body 1 via a fuel supply pipe 35 so that a liquid fuel such as waste oil can be supplied to the incineration chamber 2a. That is, since a large amount of air can be supplied to the incinerator as described above, it is possible to incinerate at a high temperature, and liquid fuel such as waste oil can also be efficiently burned. A valve 35a is provided in the fuel supply pipe 35, and the supply amount of fuel is appropriately adjusted by opening and closing the valve.

According to the incinerator having the above structure, the charging door 3
After a is opened and various garbage is put into the incinerator 2a, it is ignited and incinerated. In this case, since a large amount of air is sent into the incineration chamber 2a by the blower 25 from the openings 20 formed on the side wall and the lower surface wall thereof, complete incineration at high temperature becomes possible, and the cyclone described above is obtained. In combination with the exhaust chamber of the structure, generation of black smoke, dust smoke, residual ash, etc. is suppressed as much as possible. As a result, it is possible to treat industrial waste such as tires and waste plastic, and it is also possible to incinerate waste oil as described above.

Further, since the incineration chamber 2a is surrounded by the tank 2b containing water, the inner wall is not damaged by high heat, and it is not necessary to attach a lining member such as refractory bricks. Therefore, the structure is simple, the durability is good, and the maintenance is easy. Since the water in the tank 2b heated by incineration can be circulated and used, by installing it in a facility that uses hot water such as heating, for example, various facilities such as a greenhouse house and an aquaculture farm,
It is possible to reduce the running cost.
