FIG. 1 is an overall sectional view of a smoke exhaust device of a refuse incinerator according to the present invention, and FIG. 2 is a plan view thereof. The incinerator 1 is formed by stacking heat-resistant bricks in a cylindrical shape, and covers the top surface thereof with a lid 3 provided with a chimney 2 in the center of a cone. Two horizontal rails 4 are disposed on the left and right of the upper part of the incinerator 1, and a plurality of wheels 5 running on the rails 4 are provided on the lid 3.
Is provided, and the top surface of the incinerator 1 is opened or closed by sliding the lid 3. The chimney 2 is erected at the center of the lid 3, rises upward, bends the tip at 90 degrees, turns the tip sideways, and turns the tip in the sliding direction of the lid 3. In the center of the inside of the incinerator 1, an air supply cylinder 6 is erected vertically from the bottom. The air supply cylinder 6 is provided with a plurality of through-holes 7 at a constant interval from the bottom surface in a plurality of steps at the same circumference, and the upper end is closed. The through hole 7 is bored at an angle of 10 to 15 degrees obliquely downward from the axis of the air supply cylinder 6, and a blower 8 is connected to the lower end of the air supply cylinder 6. A roster 9 is horizontally arranged above the first-stage through hole 7 from the base of the air supply cylinder 6, and a ash intake (not shown) is provided on the lower side wall of the incinerator 1 partitioned by the rostr 9, toward the front. ) Is provided.

[0006] A smoke exhaust purifier 10 is provided adjacent to the sliding direction of the lid 3, and an inlet 12 for inserting the tip of the chimney 2 is opened in the side wall of the housing 11. The slide 3 is slidably inserted into the housing 11. FIG.
As shown in the figure, the tip of the chimney 2 is shifted obliquely from the center of the flue gas purifier 10 and
Avoid contact with 3. Even if the lid 3 is returned and the top surface of the incinerator 1 is closed, the end of the chimney 2 remains
The length of the chimney 2 is secured so as not to come off the side wall of the stack.
The inner wall of the casing 11 facing the tip of the chimney 2 of the flue gas purifier 10 is covered with a heat-resistant material such as ceramics so as to withstand high-temperature exhaust discharged from the chimney 2. An exhaust chimney 13 protruding upward is attached to the center of the ceiling of the smoke exhaust purifier 10, an exhaust port 14 is provided at an upper end of the exhaust chimney 13, and the lower end thereof is inserted into the housing 11 long. An air supply pipe 15 is erected at the center of the bottom of the exhaust gas purifier 10, the upper end thereof is inserted from the lower end of the exhaust chimney 13 to a predetermined height, and the other end is connected to the blower 8. Further, a water supply pipe 16 is attached to a lower side wall of the smoke exhaust purifier 10, water is supplied from a water supply tank 17 to a predetermined water level, and the water level is maintained by a float water supply valve 18 provided in the water supply tank 17.

The lid 3 of the incinerator 1 is constructed as described above.
Slide along the rail 4 to open the top surface of the incinerator 1. The lid 3 may be opened and closed as appropriate to fully open the refuse to be incinerated first, or to ignite the refuse, or to replenish the outside air during the combustion to increase the fire. In any case, the chimney 2 slides while being inserted into the inlet 12 of the exhaust gas purifier 10. Garbage is put into the incinerator 1, then flammable newspaper or the like is ignited and put in, the lid 3 is closed, and incineration of the garbage is started. After the heat becomes strong, the blower 8 is driven and the air supply cylinder 6 is turned on.
Air is fed into the incinerator 1 through the through hole 7 to start combustion.
By partitioning the base of the air supply cylinder 6 up and down by the rostr 9, clogs accumulate at the bottom of the incinerator 1 and block the through holes 7 to prevent incomplete combustion. Furthermore, a high-pressure air reservoir is formed below the rostr 9 through the first-stage through-hole 7, and an upward air flow passes through the rostr 9 and between the refuse. The air discharged from the through hole 7 at the upper part of the air supply cylinder 6 is heated through the space between the burning refuse and hits the inner wall of the incinerator 1 to heat the inner wall of the incinerator 1 and is incinerated by the air rising from the roaster 9. The refuse in the incinerator 1 is burned by increasing the heat concentration in the center of the furnace 1. In addition, the lid 3 is slightly opened during the combustion, and the outside air is sucked through the gap between the lid 3 to increase the fire in the incinerator 1 and promote the incineration of refuse.

[0008] The soot and high-temperature exhaust gas generated by combustion is introduced into the exhaust gas purifier 10 through the chimney 2 of the lid 3. As shown in FIG. 2, this flue gas is discharged tangentially along the inner wall of the flue gas purifier 10, so that the flue gas purifier 1
The inside of the cylinder rotates in a swirl shape around the exhaust chimney 13, and incomplete combustion products such as soot in the flue gas fall to the bottom of the flue gas purifier 10. On the other hand, outside air is blown in from the blower 8 through the air supply pipe 15 to generate a flow of air that passes through the exhaust chimney 13 and is exhausted from the exhaust port 14. It is discharged out of the smoke purifier 10. As a result, an exhaust flow that descends while rotating around the exhaust chimney 13 is generated inside the exhaust gas purifier 10. Furthermore, flue gas purifier 1
0 is filled with water to a certain water level, so that the dust contained in the descending smoke exhaust falls into the water, and the exhaust chimney 1
The dust in the exhaust gas discharged from 3 is removed. In addition, due to the temperature of the exhaust gas and the rise in the temperature of the inner wall of the flue gas purifier 10, the water at the bottom is also heated and becomes steam to rise in the flue gas purifier 10 to remove incomplete combustion products such as soot in the exhaust gas. Adsorb and fall,
The effect of removing dust from exhaust gas collected and discharged in water can be improved.
