Since the incinerator 1 employs a gasification combustion method, the fuel nozzle 5 does not always supply fuel, and the fuel nozzle 5 is positioned as an “assisting nozzle”.

At this time, the combustion chamber 3 of the incinerator 2 is provided with a diffusion pipe 6 extending in the vertical direction for communicating with the blower 4 and supplying air into the combustion chamber 3. A plurality of diffused hole portions 7 formed at different positions are provided, and a temperature sensor 8 for detecting the temperature in the combustion chamber 3 of the incinerator 2 is provided, and the fuel is detected by a temperature detection signal from the temperature sensor 8. A control means (also referred to as a “control unit”) 9 for controlling the amount of fuel supplied from the nozzle 5 is provided, and air is sent from the blower 4 into the diffusion pipe 6 so that each air diffuser 7 in each stage is provided. A plurality of air curtain layers 10 are created by jetting air in a horizontal direction from each other, a plurality of combustion areas 11 are formed between the plurality of air curtain layers 10, and the waste is generated at the bottom of the incinerator 2. During combustion, waste is liquefied and vaporized. The gas in the upper layer of the high temperature combustion area 11 and configured to burn gasified.

And the 1st-4th aeration hole part 7-1, 7-2, 7-3, 7-4 is formed in the stage from which the height position of the said diffusion tube 6 differs in multiple steps, for example, 4 steps | paragraphs.
At this time, the first air diffuser portion 7-1 located at the lowest position functions as an air diffuser hole for gasification and is not for creating the air curtain layer 10, so the second to fourth air diffuser holes. Compared with the parts 7-2, 7-3 and 7-4, the number of holes is reduced.
The second air diffuser 7-2 is positioned above the first air diffuser 7-1, and the third and fourth air diffuser 7 are above the second air diffuser 7-2. -3, 7-4 are formed sequentially.
In addition, when forming the above-mentioned 1st-4th air diffused hole parts 7-1, 7-2, 7-3, 7-4, compared with the 1st air diffused hole part 7-1, the 2nd-4th air diffused parts. It is also possible to form the pores 7-2, 7-3, 7-4 so that the number of holes gradually increases from the lower stage toward the upper stage.
Furthermore, regarding the hole diameters of the first to fourth air diffusion holes 7-1, 7-2, 7-3, and 7-4, all the hole diameters can be made the same size, while from the lower stage toward the upper stage, It is also possible to gradually increase the hole diameter.
Furthermore, the top portion of the diffusion tube 6 is closed by a tube lid (not shown).

Further, the temperature sensor 8 is connected to the input side of the control means 9, and the blower 4 and the fuel nozzle 5 are connected to the output side of the control means 9, respectively.
The control means 9 controls driving of the blower 4 and the amount of fuel supplied from the fuel nozzle 5 based on a temperature detection signal from the temperature sensor 8.
At this time, in the drive control of the blower 4 by the control means 9, the following control measures can be considered.
(1) Measures for realizing slow combustion in the combustion chamber 3 by adding strength to the amount of flowing air supplied with strength and weakness in the drive control of the blower 4.
In addition, it is realizable by switching a drive control state for every predetermined time as a policy which attaches strength to the drive control of the air blower 4. FIG.
(2) Measures for controlling the air blower 4 to a constant driving state so as not to change the amount of flowing air.
(3) A measure for driving and controlling the blower 4 based on a temperature detection signal from the temperature sensor 8 to change the amount of flowing air so as to make the combustion constant in the combustion chamber 3.

Further, an automatic maintenance function is added to the control means 9.
That is, when the temperature in the combustion chamber 3 of the incinerator 2 has decreased to below the required temperature, the temperature in the combustion chamber 3 is detected by the temperature sensor 8, and the temperature detection from the temperature sensor 8 is detected. Drive control of the blower 4 by the control means 9 is performed by a signal, and the temperature in the combustion chamber 3 is automatically returned to an appropriate state.

Then, air is sent from the blower 4 into the diffusion pipe 6 to blow out the air in the horizontal direction from the diffuser holes 7 of each stage, and as shown in FIG. Third air curtain layers 10-1, 10-2, 10-3 are created.
A plurality of stages, for example, three stages of first to third combustion areas 11-1, 11-2, 11-3 are formed between the first to third air curtain layers 10-1, 10-2, 10-3. .
At this time, the first combustion area 11-1 located in the lower stage can be rephrased as “lower combustion chamber”, and the second combustion area 11-2 located in the middle stage can be rephrased as “middle combustion chamber”. In addition, the third combustion area 11-3 located in the upper stage can be rephrased as an “upper combustion chamber”.
Further, when the waste burns at the bottom of the incinerator 2, the gas generated by liquefaction and vaporization of the waste is converted into a high-temperature combustion area 11, that is, the first to third combustion areas 11- 1, 11-2 and 11-3, gasification combustion is performed sequentially from the lower stage to the upper stage.

At this time, in the drive control of the blower 4 by the control means 9, the control mode for realizing the slow combustion described above, the control mode for setting the blower 4 in a constant drive state, or the amount of flowing air is varied. A control mode for making combustion constant in the combustion chamber 3 can be arbitrarily selected.

In addition, when the waste burns in the combustion chamber 3 of the incinerator 2, first, as shown by the white arrow A in FIG. Since air is ejected from the portion 7-2 into the combustion chamber 3 in the horizontal direction to form the first air curtain layer 10-1, the first air curtain layer 10-1 defines a lower position. In the first combustion area 11-1, the waste is liquefied and vaporized to generate gas.
The gas generated in the first combustion area 11-1 flows into the combustion chamber 3 from the third aeration hole 7-3 through the diffusion pipe 6 by the blower 4 as shown by the white arrow B in FIG. Since air is ejected in the horizontal direction and the second air curtain layer 10-2 is formed, the second combustion located in the upper middle layer that is partitioned by the second air curtain layer 10-2 and has a high temperature. Reach area 11-2.
The gas combusted in the second combustion area 11-2 is sent from the fourth air diffuser 7-4 through the diffusion pipe 6 by the blower 4 through the diffusion tube 6 as shown by the white arrow C in FIG. Since air is blown out horizontally into the third air curtain layer 10-3, it is partitioned by the third air curtain layer 10-3. The third combustion area 11-3 is reached, and gasification combustion is performed effectively in sequence.

A smoke detection sensor 23 is provided at the connection portion 26.
If it adds, the said incinerator 2 without a burner by a gasification combustion system will be in the state which a black smoke etc. tends to come out in the low temperature state, such as the time of ignition and fire extinguishing. Of course, when black smoke is generated, there are many possibilities of releasing harmful substances such as dioxin, so a flue that connects the smoke detection sensor 23 from the combustion chamber 3 of the incinerator 2 to the dust collecting unit 22; That is, black smoke is detected by the smoke detection sensor 23 provided at a connection site between the incinerator 2 and the dust collecting unit 22.
Then, a refractory caster 24 processed for heat resistance is connected to the discharge side of the dust collecting portion 22, and a second addition is performed by supplying fuel from the fuel tank in the vicinity of the inlet 24 a of the refractory caster 24 and performing additional combustion. A fuel nozzle 25 is provided.
At this time, as shown in FIG. 2, the refractory caster 24 is connected to the upper portion of the dust collecting portion 22 and is directed upward and then curved in the horizontal direction. A horizontal intermediate portion 24-2 extending in the horizontal direction from the downstream end of the inlet portion 24-1 and a downstream end curved downward after being connected to the horizontal intermediate portion 24-2 and directed toward the downstream end.

Fuel is supplied from the additional fuel nozzle 25 into the refractory caster 24 to perform additional combustion.
At this time, the control means 9 controls the second additional fuel nozzle 25 to perform additional combustion, so that the exhaust gas becomes high temperature, and black smoke and harmful substances in the exhaust gas passing through the refractory caster 24 are completely removed. is doing.
Accordingly, not only the problem caused when the waste is incinerated is solved, but also when the incinerator 2 is ignited or when waste exceeding capacity is put into the combustion chamber 3 of the incinerator 2 or when the incinerator 2 is incinerated. The exhaust gas generated during incineration such as during fire extinguishing can be further combusted as necessary to further promote purification of the exhaust gas.

Further, the dust collecting part 22 forms a water cooling jacket 27 on the wall part and exchanges heat with the exhaust gas flowing into the dust collecting part 22.

Accordingly, by forming a water cooling jacket 27 on the wall of the dust collecting part 22 and exchanging heat of the exhaust gas, wastes made of a high molecular weight material such as foam, plastic, rubber, etc. are simply incinerated. Instead, the heat energy generated during the incineration can be fully utilized by the heat exchange of the exhaust gas flowing into the dust collection unit 22.

  FIG. 3 shows a third embodiment of the present invention.

  The feature of the third embodiment is that in the system 31 including the waste incinerator 1, the dust collecting unit 22, the second dust collecting unit 32, and the forced suction fan 33 are disposed downstream of the incinerator 1.

The dust collection part 32 is provided and a fine dust can be removed completely.
Further, by providing the second dust collecting part 32, the flow of the exhaust gas is resisted, the flue is loaded, and the exhaust gas exhaustion may be deteriorated. Since this causes combustion, it is possible to provide the forced suction fan 33 to forcibly draw in the exhaust gas so as to smoothly exhaust the exhaust gas and achieve efficient combustion and clean exhaust.

Further, as shown in FIG. 3, a storage tank 37 is connected to the water cooling jacket 27 of the dust collecting section 22 through a water supply pipe 36, and a water supply pump 38 is provided in the middle of the water supply pipe 36. In addition, the storage tank 37 is provided with a first water supply pipe 39, a second hot water supply pipe 40, and a third drainage pipe 41 connected to each other.
Therefore, the following effects can be obtained by exchanging heat of the exhaust gas with the water cooling jacket 27 of the dust collecting unit 22.
(1) Hot water can be obtained by heat exchange of exhaust gas, and the hot water can be effectively used for hot water supply or heating.
(2) Since the high-temperature exhaust gas can be cooled by heat exchange, the environment-friendly exhaust can be performed by preventing the binding of harmful substances.

  The present invention is not limited to the first to third embodiments described above, and various application modifications can be made.
