FIG. 3 shows an embodiment of the present invention.
It will be described based on. (The air duct 32 and the exhaust heat medium intake pipe 106 in FIGS. 2 and 3 are the same and serve as ventilation holes.)

The cooled groundwater or the like is heated and can be used for an external bath or the like from the drain pipe 110.

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A smokeless chimney coil and a combustion method according to embodiments of the present invention will be described in detail below.

As shown in FIG. 3, when the dump truck raises the loading platform, the loading sensor 35 'provided at the air inlet 35 opens the incineration material collection door 24 of the drying chamber A to take in the incineration material. 'Can be linked with the hand switch.

Next, when the incinerator sensor A 'in the drying chamber A is turned on by the blower (blower) 101 provided in FIG. 2, the air suction flow into the intake port 35 shown in FIG. When confirmed by ', the ignition burner 5' is switched on.

The flame of the ignition burner 5 'heats the combustion chamber B at a high temperature, and the hot air heats the heat exchange smoke collecting hood 4 and the hood upper slope 2 of the drying chamber A to raise the air. The heat energy is converted into electricity or the like in the power generation system of FIG. The air is converted into low-temperature air, which is accelerated by the blower 101 and discharged to the outside via the dust collector 102. The dust collector is operated as needed.

When the temperature in the drying chamber A rises and the incinerated material dries, the humidity sensor 1 'gradually opens the door 22 and slides down into the combustion chamber B to start combustion, and complete ignition occurs. ', The ignition burner is switched off, but if the temperature of the combustion chamber drops, the ignition sensor 22' switches on the ignition burner 5 'to turn on and heat the ignition. When the fire extinguishing button is pressed, the hydraulic cylinder 11 'closes the air port with the fire extinguishing valve 12 and the fire is extinguished.

The combustion temperature of the combustion chamber B is controlled by the air mixing amount of the fire extinguisher valve 12 and is incinerated. Smoke gas generated by extending the durability of the combustion chamber B by low-temperature combustion is previously energized and heated to a high temperature. The inside of the chimney coil 9 'is energized and completely burned.

The chimney coil 9 'is formed of a material having a high melting point, such as tungsten, so that the smoke gas is not melted even if it is burned at an extremely high temperature. The energization is stopped and the combustion temperature is lowered to return to normal combustion.

In order to adjust the combustion speed of the chimney coil 9 ', a screw is cut into the air port cap 36, and the outside of the chimney coil 9' is cut off with smoke gas to reduce the temperature of the chimney coil 9 '. Regulating and fast burning explosions of smoke gases at this location are not possible due to the lack of added oxygen in the air.

The inside of the chimney coil 9 'is a blower 101 shown in FIG.
NOx (nitrogen oxides) is hardly produced due to negative pressure combustion, and dioxin and CO
And other harmful gases are also close to zero by the air mixing valve.

The outside air is sucked from the suction port 35 shown in FIG. 3 by the suction pressure of the blower 101 shown in FIG.
The air heated by the heat exchange port 3 is supplied from a heating air pipe 3 ′ provided in the combustion chamber B, and the incinerated material is burned evenly.

The air outside the apparatus shown in FIG.
The heating air which has been cross-exchanged by the heating air pipe 4 ′ through the heating air pipe 4 ′ through the mixing air inlet valve 29 is supplied to the air bypass 1.
The gas is sucked into the chimney coil 9 'through 0' and is simultaneously mixed with the smoky gas from the coil intake port 10, so that the inside of the chimney coil 9 'is heated to a complete combustion at a high temperature by a synergistic effect of electric heating. The smoked gas and the like that have been thermally decomposed are smokeless, cooled down via a tornado generator by the blower 101 shown in FIG.

The smokeless oxygen-free gas from the dust collector 102 is absorbed by the exhaust heat medium intake pipe 106 and the oxygenated air from the intake port 35 at the same time, and the mixing ratio is determined by the fire extinguisher valve 12. The thermal power is adjusted, and a large amount of aerobic air can be sent to increase the incineration speed in order to forcibly discharge a large amount of incineration heat to the outside by using the exhaust heat medium.

When the temperature of the smokeless exhaust gas absorbed in the hot air duct 32 is too high, the exhaust of the heat medium is directly mixed in the bypass pipe 109 by the heat medium bypass on-off valve 108 and cooled.

Since all the air lines are performed by a single blower (blower) 101, the pressure is released in the dust collector 102 in FIG. There is no danger of heat explosion due to accumulation.

The blower (blower) 101 shown in FIG. 2 is designed to rotate at a high speed and increase the combustion speed to supply a large amount of heat energy when a large power generation output is required.

The negative pressure energy (air volume × air pressure) of the blower (blower) 101 is divided by the cross-sectional area of the opening of the valve and the resistance of the air line, the flow rate is determined, and is input to the temperature sensor computer to determine the temperature of each part. The opening / closing amount of the valve is adjusted by moving the hydraulic cylinder connected to the valve using a thermometer.

Due to the above-mentioned mechanism, even if there is a large difference in heat calorie depending on the kind of incinerated material, the temperature change is drastically reduced by adjusting the amount and the burning speed so that stable high speed combustion and high power generation can be performed. ing.

In one example, the amount of electric current of the electric power sold from the generator goes in the increasing direction, and the output of the blower is increased by sensing the amount of electric current as a sensor, thereby increasing the combustion speed and increasing the heat medium exhaust flow rate. As a result, the combustion temperature does not change much, but a large amount of heat calories are transferred so that it can respond to the heat absorption of the power generation system.

When an easily combustible gas such as a tire or the like containing a large amount of smoke gas is burned, the combustion temperature is sensed by a sensor and the ratio of air to heat medium exhaust is adjusted by the digestion valve 12, and the smoke gas is removed. The chimney coil 9 'made of tungsten material is heated by energization to be burned at a high temperature until smokeless, and further heat-exchanged and heated by a heating air pipe 4' from a mixing inlet 33 to feed heated air to an air bypass 10 '. It absorbs more oxygen in the air, and the amount of air is computer-controlled by the compound intake valve 29.

In the event that the automatic operation computer for temperature control or the like has failed and has reached a dangerous temperature, although not shown, the low-melting lead balls arranged in each part are melted and the sprinkler SW (switch) is connected between two points. At the same time, the hydraulic cylinder of each valve operates directly to extinguish the fire.

[0040]

According to the present invention, the burning speed can be freely controlled in order to extract the heat calories required for power generation, regardless of the kind of incineration, and furthermore, oxygen-free air of smokeless exhaust is used as a heat medium. Since the heat can be transferred quickly in the incinerator by using it, a large amount of aerobic air can be sent to speed up the incineration.

In order to prevent the high temperature oxidation of the furnace wall, to increase the durability and to make it economical, a smoke gas is generated by low temperature combustion,
The product to be burned next is dried by the low-temperature heat, and the moving means is low-cost with a dropping type, and the high-temperature combustion chamber of the flammable gas is compactly formed so that it can be replaced durably, and a high-performance, low-cost product I can do it.

Furthermore, the high temperature combustion chamber can be freely controlled by forming a chimney coil in the high temperature combustion chamber of the flammable gas from a material having a high melting point such as tungsten material and heating the current, and it is non-polluting from ignition to digestion. In addition to being able to incinerate, it has the effect of being able to generate cheap electricity using the waste heat.
