[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combustion balance device for avoiding overheating of a refuse incinerator.

[0002]

2. Description of the Related Art In a conventional refuse incinerator, a large amount of black smoke may be generated when a large amount of refuse is thrown in at once or refuse having a high combustion calorie such as a tire is incinerated. This is because the garbage exceeded the incineration capacity of the incinerator and the furnace was overheated. As a solution to this problem, the present inventor has previously invented and applied for a combustion balance device for a refuse incinerator. In this combustion balance device, an air supply cylinder is erected at the center of the bottom of the incineration cylinder, the upper end of the air supply cylinder is closed, a number of blasts are provided radially on the side wall, and water is supplied to the upper end of the air supply cylinder. With a structure in which the pipes are viewed, outside air is blown into the air supply cylinder by a blower during incineration of refuse, and is blown out from the fuze to promote combustion.However, when it is overheated, the water supply pipe directs it toward the upper end of the air supply cylinder. Supply water. This water descends along the side wall of the air supply cylinder, and is sprayed into the incineration cylinder in a mist state by the air blown out from the blast port of the air supply cylinder. As a result, the overheat condition is eliminated, and the combustion in a well-balanced manner prevents the generation of black smoke. However, the overheating state in the incinerator is not uniform depending on the type and amount of waste to be charged, and it is necessary to adjust the amount of water supplied from the water supply pipe while checking the combustion state of the waste every time.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to detect such an overheated state of an incinerator and automatically supply water based on the detection result.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a refuse incinerator according to the present invention. In the refuse incinerator 1, a refuse incineration tube 2 is formed into a bottomed cylindrical shape with an iron plate, and a refuse inlet 3 facing obliquely upward is formed on an upper surface thereof. The dust inlet 3 is closed by a dust inlet 6 attached to the canopy 5 via the hinge 4. Chimney 7 at the top of incinerator 2
And the outer periphery thereof is covered with a smoke buffer tube 8. 9 is a rain shield. An overheat detection sensor 10 is provided in the chimney 7 through the smoke buffer tube 8.

At the lower part of the front of the incinerator 2, an ash outlet 12 is provided.
Ash extraction door 13 is provided. At the bottom of the incineration cylinder 2 is installed a scoop-shaped rooster 14, and a dust collecting section 15 is formed below the scoop 14. The dust push-up protrusions 20 stand upright on the upper surface of the roaster 14 to secure ventilation in the incinerator 2. The inner cylinder 16 is placed on the roaster 14 to form a gap between the inner cylinder 16 and the incineration cylinder 2. An air supply tube 17 is erected vertically through the center of the rostrum 14, and a blower 18 is connected to its base end. The upper end of the air supply cylinder 17 is closed without opening. A plurality of spouts 19 are formed in a large number of stages at regular intervals on the peripheral wall of the air supply cylinder 17. The lowermost fumarole 19 is the dust collector 15
Look into. The blast port 19 is bored at an angle of 10 to 15 degrees obliquely downward from the axis of the air supply cylinder 17. A water supply pipe 21 is erected vertically from the base end of the air supply cylinder 17 through the air supply cylinder 17, the upper end thereof is opened at the upper end of the air supply cylinder 17, and the other end is pulled out of the incineration cylinder 2, On the way, the solenoid on-off valve 1

[0007] With the above configuration, the refuse input cover 7 of the refuse incinerator 1 is opened, refuse is charged into the incinerator 2, and flammable newspaper or the like is ignited from the refuse input cover. Close 7. After the heat is increased, the blower 18 is driven to send outside air into the inner cylinder 16 through the air supply cylinder 17.
The exhaust gas generated by the incineration of the refuse rises from the inner cylinder 16 to the upper part of the incineration cylinder 2, and a part of the exhaust descends from the gap between the inner cylinder 16 and the incineration cylinder 2 to prevent overheating of the incineration cylinder 2. Most of the other exhaust gas enters the chimney 7 directly, passes through the smoke buffer tube 8, removes sparks and solids from the flue gas, and discharges it to the atmosphere.

When a large amount of refuse is input or a large amount of high-calorie refuse such as tires is input, the inside of the incinerator 2 becomes overheated due to the combustion, and the air from the air supply cylinder 17 is discharged. Insufficient supply of gas may cause incomplete combustion to generate a large amount of black smoke, and a flame may blow out into the chimney 7. At this time, when the overheating detection sensor 10 whose tip projects into the chimney 7 detects an overheating state (for example, about 750 ° C.), it sends a signal to the electromagnetic opening / closing valve 11 and
Is driven and opened, water is injected from the water supply pipe 21 to the upper end of the air supply tube 17, and the water descends along the outer periphery of the air supply tube 17, and is incinerated in the form of a mist due to the air flow ejected from the blast port 19. It spreads in the cylinder 2, thereby eliminating the overheating state in the incineration cylinder 2 and promoting the combustion of refuse. When the overheat state in the incinerator 2 is eliminated, the overheat detection sensor 10 detects this, and as a result, the electromagnetic on-off valve 11 closes and the water supply stops. The mounting position of the overheat detection sensor 10 is not limited to the inside of the chimney 7 and the incinerator 2
The same effect can be obtained even if it is mounted on the upper part of the.
Instead of penetrating the water supply pipe 21 from the base end of the air supply pipe 17 and opening the front end to the upper end of the air supply pipe 17 to inject water, the front end of the water supply pipe 21 directly penetrates the canopy 5 and air from above. The same effect can be obtained even if the electromagnetic on-off valve 11 provided in the middle of the water supply pipe 21 is controlled by the signal of the overheat detection sensor 10 while looking at the upper end of the supply cylinder 17.

A thermocouple or the like is used as the overheat detection sensor 10 to directly detect the temperature of the air rising in the chimney 7 or to contact the side wall of the chimney 7 to detect the temperature. The valve 11 is opened. FIG.
As shown in detail, a flame sensor 24 that detects ultraviolet rays is used as the overheat detection sensor 10, a flame that blows out into the chimney 7 at the same time as smoke is detected by the ultraviolet rays, and a signal is sent to the electromagnetic on-off valve 11. The electromagnetic on-off valve 11 is opened. The frame sensor 24 is mounted in a cylinder 25 that blocks external light. The end of the cylinder 25 is viewed into the chimney 7, and when a flame blows out into the chimney 7, the ultraviolet ray is detected. Cylinder 25
Cuts off the external ultraviolet rays, and detects only the ultraviolet rays generated from the flame in the chimney 7 by the frame sensor 24. The overheating detection sensor 10 detects the overheating state in the incineration cylinder 2, opens the electromagnetic on-off valve 11 and supplies water to eliminate the overheating state in the incineration cylinder, thereby suppressing the generation of black smoke and burning in a well-balanced manner. An environmentally friendly stable incinerator can be provided. At the same time, the service life of the incinerator 2 can be extended by preventing overheating of the incinerator 2.

FIG. 2 is a sectional view of a refuse incinerator showing another embodiment of the present invention. In the figure, a water storage tank 22 is arranged close to the incinerator 2 and connected to the water supply pipe 21 from the water storage tank 22 via a water supply pump 23. The water supply pipe 21 penetrates through the canopy 5 and protrudes into the incineration cylinder 2, and its tip is viewed from the upper end of the air supply cylinder 17. Further, an overheat detection sensor 10 is attached to the upper side wall of the incinerator 2 and the overheat detection sensor 1
The output line of 0 is connected to the control unit of the water supply pump 23, and the start or stop of the water supply pump 23 is controlled by the signal of the overheat detection sensor 10. With the above configuration, when incineration of the incinerator 1 proceeds in the incinerator 2 and the incinerator 1 is overheated, the overheat detection sensor 10 detects the overheating in the incinerator 2 and sends the signal to the control unit of the water supply pump 23. The water supply pump 23 is driven to supply water from the water storage tank to the water supply pipe 21, and water is injected from the tip of the water supply pipe 21 to the upper end of the air supply cylinder 17. The injected water descends along the outer circumference of the air supply cylinder 17 and becomes mist-like due to the air flow ejected from the fuze port 19 and spreads into the incineration cylinder 2, thereby eliminating the overheated state in the incineration cylinder 2 and burning. To promote. When the overheat state is eliminated, the water supply pump 23 is stopped by the overheat detection sensor 10, and the water supply is automatically stopped.
