The dry distillation incinerator of the present invention has a distillation chamber, a radiation cylinder, a burner, a combustion chamber (including a combustion cylinder), a blower, and an exhaust cylinder as constituent requirements. The distillation chamber accommodates the incinerated object and has an outlet (dry gas outlet) of dry gas generated from the incinerated object. The radiant barrel penetrates the inside of the distillation chamber and radiantly heats the incineration object outside the barrel by the flame in the barrel to generate dry gas. The burner supplies flame (burner combustion flame) into the bin from the inlet of the radiator. The combustion chamber has an air inlet communicating with an outlet of the dry gas and an outlet of the radiant cylinder. The blower sends combustion air from the air inlet into the combustion chamber to burn dry gas. The exhaust cylinder is connected to the combustion chamber, discharges the exhaust gas generated by the combustion out of the furnace, and at the same time draws dry gas in the drying chamber into the combustion chamber by a draft action.

In the dry compartment, the radiator penetrates through the inside, and the combustion chamber is simply the outlet of the radiator, the dry gas outlet, the air inlet, and the intake port of the exhaust cylinder. Since it is sufficient to install a burner, a fan motor, or the like outdoors, the dry distillation incinerator of the present invention has a very simple furnace structure and is excellent in operability and maintainability. In addition, the radiation can be easily produced using a stainless steel pipe, heat-resistant steel pipe and the like. The cross-sectional shape of the copying cylinder is not particularly limited. In addition, the radiation can be any one of a straight pipe, a curved pipe, a branch pipe. In addition, the distillation chamber and the combustion chamber can be manufactured using ordinary refractory materials, steel materials, etc.

The present invention has such a simple furnace structure and very high dry distillation and combustion efficiency. That is, since the radiator penetrates the inside of the distillation chamber, the burned object is not exposed to the burner combustion flame in the bin and is heated only by radiant heat from the outer surface, so that no ignition occurs, and dry distillation and gasification in an anoxic state proceeds and The efficiency is almost 100%. Therefore, dust (soot and dust) hardly occurs. The generated dry gas is sucked into the combustion chamber from the dry gas outlet by the draft effect of the exhaust cylinder. The dry gas entering the combustion chamber is mixed with the burner combustion flame from the radiant outlet and the combustion air from the air inlet, and burns at a combustion efficiency of almost 100% at the combustion temperature (800 ° C. or higher) based on the emission standard. The exhaust gas generated by this combustion is a clean gas containing almost no smoke, odor, flame, dust, CO, dioxins, or other harmful gases.

As described above, in the present invention, the incinerator is separated into a dry chamber and a combustion chamber, so that only the dry gas and gasification of the incinerated object can be burned in the dry chamber, and only the dry gas is burned in the combustion chamber. Very high dry distillation incinerators have been realized.

The dry distillation incinerator of the present invention is operated, for example, as follows.

Put the waste into the distillation chamber ⇒ Burner ignition ⇒ Start the blower ⇒ Start the feeding of combustion air with a delay (e.g. 10 minutes) ⇒ Air flow rate of the burner so that the temperature in the combustion chamber is a predetermined value (e.g. 800 to 900 ° C) And adjusting fuel flow rate (automatic adjustment) ⇒ After a predetermined time (depending on the throughput, for example, about 2 hours in some cases, for example about 6 hours in many cases), and then performing interval combustion (below) as necessary ⇒ blower Stop, burner digestion⇒ We extract incineration residue from distillation room.

In addition, in the present invention, the carbonized product (carbon) remaining in the furnace after dry burning and gasification of the burned material and burning dry gas is opened by the draft action of the exhaust cylinder by opening the cover of an air intake port that is properly installed, such as a cover of the ash outlet. It can be aspirated in the furnace and very easily burned and combusted.

Next, a preferred embodiment of the present invention will be described.

Although the radiation form is not specifically limited by the arrangement | positioning form, It is preferable to arrange | position in a longitudinal length or a lateral length from a viewpoint of ease of description and manufacture. The number of copy bins is not particularly limited and may be singular or plural. In addition, when arrange | positioning in a lateral length, it is preferable to make the position of a radiation cylinder below the inner height direction center (more preferably 1/4 below) of a distillation chamber. The reason is that the waste, which is a burning object, is bulky before it is distilled and deposited near the ceiling of the distillation chamber, but when the distillation starts, the volume quickly decreases, and for most of the distillation time, the height center of the distillation chamber ( This is because the surface of the object to be burned is lower than that of the radiation cylinder even if the radiation cylinder is disposed in the area of 1/4) or more from the bottom, and the heating and drying efficiency is lowered.

In addition, it is preferable that the outlet of the dry gas is located around the exit portion of the radiation barrel. By doing so, the distillate gas flows near the outer wall of the radiator, which is a hot heat source, enters the combustion chamber with sufficient heating (preheating), and as soon as it enters, it mixes with the burner combustion flame containing excess air from the radiant outlet, making it more efficient. Is burned.

In addition, it is preferable that the said combustion chamber is made into a cyclone shape or a normal combustion cylinder. By making the combustion chamber into a cyclone shape, even if dust is generated in the distillation chamber and flows into the combustion chamber, it can be collected and collected at the bottom of the combustion chamber. In the case of the cyclone shape, it is preferable to connect the dry gas gas outlet and the air inlet to the side of the combustion chamber (more preferably, the upper portion, and more preferably the side tangential direction) so that the turning downward airflow is generated in the combustion chamber. . In the case of the cyclone shape, it is also preferable to position the intake port of the exhaust cylinder below the inside of the combustion chamber so as to lengthen the stroke of the air flow in the combustion chamber to increase the combustion time of the dry gas.

In addition, a smaller furnace structure can be obtained by using the combustion chamber as a combustion cylinder. In addition, the combustion cylinder also has the advantage that it can be more easily manufactured using a stainless steel pipe, heat-resistant steel pipe and the like. The cross sectional shape of the combustion cylinder is not particularly limited. In addition, it is preferable to arrange the combustion cylinder in the longitudinal length because the semicircular column that becomes the upper side may be overheated when the combustion cylinder is disposed in the transverse direction or at an angle. Moreover, in the combustion cylinder arrange | positioned at the longitudinal length, in view of combustion efficiency and equipment downsizing, it is preferable that the said dry gas outlet is connected to the side part (more preferably, the lower part) of a combustion cylinder, and the said air inlet is connected to the bottom part of a combustion cylinder. desirable. In the combustion cylinder arrange | positioned at the longitudinal length, it is preferable to also connect the intake port of the said exhaust cylinder to the uppermost part of a combustion cylinder from a viewpoint of size reduction of equipment. In addition, the combustion cylinder may be singular or plural. In the case of having a plurality, the exhaust cylinders can be separately provided for each combustion cylinder, and the outlets can be collectively collected in a collective combustion method.

Moreover, it is preferable that the air flow path leading to the air inlet of a combustion cylinder makes at least one part thereof follow a combustion cylinder. This is because the cylinder wall is cooled by the combustion air flowing along the combustion cylinder to prevent heat damage of the combustion cylinder, and at the same time, the combustion air is preheated by the heat of combustion inside the combustion cylinder to further improve the combustion efficiency.

Further, in the present invention, it is preferable to directly contact or integrate the partition element of the distillation chamber and the compartment element of the combustion chamber at least in part. By doing in this way, heat generated by combustion of the dry gas in the combustion chamber is effectively transferred to the dry gas chamber through the portion of the partition element which is directly contacted or integrated, thereby further promoting the drying and gasification.

The present invention is also described in (Bl) and (B2) below, in addition to what has been described so far (incinerator through a radiation chamber in a distillation chamber: type C incinerator) as a means for achieving the above object. Also included is an incinerator (referred to as type B incinerator) in which the radiation cylinder (outlet) and the combustion cylinder (inlet) are connected in the distillation chamber.

(B1) A dry storage chamber having a dry gas outlet (dry gas gas outlet) for accommodating the to-be-burned object and generated from the burned-in object, and at a predetermined height position therein through the bottom of the inside of the dry-drying chamber or additionally above it. A radiant barrel arranged to reach the radiant heat generated by the flame inside the barrel to radiate heat to generate dry gas from the incinerator, a burner for supplying flame into the barrel at the inlet of the radiant, and an outlet of the radiant barrel. A blower for sending combustion air into the combustion cylinder through the combustion cylinder having an air inlet and an air passage leading from the outside of the distillation chamber to the air inlet to combust the dry gas, and the exhaust gas generated by the combustion. And an exhaust cylinder for discharging out of the furnace, wherein the dry gas is supplied to the junction between the outlet of the radiation cylinder and the combustion cylinder. A gun-flow furnace wherein a sphere is formed.

(B2) A distillation chamber which contains an incineration object and has an outlet (dry gas outlet) of dry gas generated from the incineration object, and is disposed at a longitudinal length from the outside of the distillation chamber to a predetermined height position in the flame in the barrel. By radiantly heating the incinerator outside the cylinder to generate dry gas from the incinerator, a burner for supplying flame into the cylinder from each inlet of the radiator, and the outlets of the plurality of radiation cylinders. A blower which sends combustion air into the combustion cylinder through the combustion cylinder having an air inlet, an air passage leading from the outside of the distillation chamber to the air inlet to combust the dry gas, and exhaust gas generated by the combustion. And an exhaust port for discharging, and an outlet of the dry gas is formed at a junction between the outlet of the radiation tank and the combustion cylinder. Haida gun-flow furnace, characterized in that.

In these B type incinerators, the predetermined height position is preferably set to a height position of (0.15 to 0.75) × H with respect to the total height H in the drying chamber based on the bottom of the drying chamber. More preferably, it is (0.25-0.65) * H.

In type B incinerators, a dry gas outlet is formed at the junction between the outlet of the radiation cylinder provided in the distillation chamber and the inlet of the combustion cylinder. Since the exhaust cylinder is connected to the outlet of the combustion cylinder as in the case of the C type incinerator, dry gas generated in the dry chamber is sucked by the draft action of the exhaust cylinder, passes through the dry gas outlet, enters the combustion cylinder, and is almost completely burned. In addition, since the inside of the cylinder is under negative pressure in the junction at the junction, as compared with the barrel inside the barrel, the burned object is dried and gasified in an oxygen-free state without burner combustion sparks leaking into the barrel. In addition, since the combustion cylinder is in the distillation chamber, the heat generated by burning dry gas in the combustion cylinder is supplied as radiant heat to the distillation chamber, and the combustion air flowing through the interior of the distillation chamber and reaching the air inlet is preheated. Drying and gasification are further promoted. In addition, it is preferable that at least a portion of the air passage is along the combustion cylinder so that the combustion cylinder can be cooled by the combustion air, thereby preventing heat damage of the combustion cylinder due to overheating.

In (B1), the radiator is arranged so as to reach a predetermined height position from the outside of the distillation chamber by passing through the bottom of the inner part or further upwards thereof, so that the radiator can be arranged in a longitudinal length. The effective reach has been extended to further improve the distillation efficiency. In addition, in (B2), by providing a plurality of radiation bins arranged in the longitudinal length, it was possible to obtain a large-scale incinerator which can be incinerated efficiently with a simple furnace structure, especially when there is a large amount of waste treatment. In addition, the operation method of a B type incinerator is the same as that of a C type incinerator.

It reacts with the combustion air 12 supplied through the inlet 14 to burn almost completely. The clean and harmless exhaust gas 13 produced by this combustion is discharged out of the furnace from the exhaust cylinder 50.

(2) Fig. 2 is a schematic side cross-sectional view showing an embodiment (Example 2) of the incinerator C of the present invention. In this embodiment, the radiation cylinder 2 penetrates the interior of the distillation chamber 1 containing the object to be burned (not shown) in the longitudinal length, and the radiation cylinder 2 opened outside the distillation chamber is the inlet of the lower end ( It is connected to the burner 3 in 2A), and it communicates with the combustion cylinder 4 arrange | positioned outside the distillation chamber 1 at the exit 2B of an upper end part. The distillation gas outlet 8 is formed by a hole drilled around the radiating chamber through portion of the ceiling of the distillation chamber, and the opening and the inlet of the combustion cylinder 4 are connected by a distillation gas flow passage 16 formed in a labyrinth shape. . The dry gas flow path 16 is in contact with the drying chamber and the combustion cylinder. The air inlet 14 is provided near the combustion cylinder inlet and is connected to the blower 9 through the air flow passage 15. A part of the air flow path 15 (part close to the air inlet 14) is formed to follow the combustion cylinder 4 using a double pipe structure. The exhaust cylinder 50 is attached to the outlet of the combustion cylinder 4.

When the burner 3 is ignited, the flame 5 is supplied into the radiation chamber, the radiation cylinder 2 is heated, and the radiant heat 6 is released into the drying chamber 1, whereby the burned object is heated to an oxygen-free state. Dry distillation and gasification generate | occur | produce dry gas (11). The generated dry gas 11 is sucked into the combustion cylinder 4 through the dry gas discharge port 8 by the draft action of the exhaust cylinder, the flame 5 supplied from the outlet 2B of the radiation cylinder, and the blower 9. It reacts with the combustion air 12 supplied through the air inlet 14 from the gas and is burned almost completely. The clean and harmless exhaust gas 13 produced by this combustion is discharged out of the furnace from the exhaust cylinder 50.

The dry distillation gas 11 is kept warm or preheated when passing through the dry distillation gas passage 16 in contact with the distillation chamber and the combustion cylinder, and the combustion air 12 is the combustion cylinder extension portion (double pipe structure) of the air passage 15. Combustion part becomes high because it is preheated by the radiant heat of the flame 5A. Moreover, the combustion air 12 cools the combustion cylinder by passing through the combustion cylinder extension part, prevents the heat damage, and extends the lifetime. Further, since the dry gas 11 enters the combustion cylinder through the labyrinth-type dry gas gas flow passage 16, even if dust is generated in the dry gas chamber and mixed in the dry gas 11, the labyrinth acts as a cyclone. The rinse-shaped dry gas flow path 16 is collected and collected and does not reach the combustion cylinder.

(3) Fig. 3 is a schematic side cross-sectional view (a) and a schematic planar cross-sectional view (b) showing an embodiment (Example 3) of a type C incinerator of the present invention. In this embodiment, the radiation cylinder 2 penetrates the interior of the distillation chamber 1 containing the object to be burned (not shown) in the transverse length, and the radiation cylinder 2 whose both ends open out of the distillation chamber has one end. It is connected to the burner 3 at the inlet 2A (for example, the left end), and is led into the combustion chamber 7 adjacent to the distillation chamber 1 at the outlet 2B of the other end (for example, the right end). The penetrating position of the copying cylinder 2 is in the center part of the width direction of a distillation chamber, and the lower part (position lower than 1/2 of the height in a distillation chamber) of a height direction. The dry gas outlet 8 is formed by a gap between the radiation through hole and the radiation through the side wall of the drying chamber. The combustion chamber 7 is made into a cyclone shape. A part of the side wall of the combustion chamber is integrated with that of the distillation chamber. The air inlet 14 is provided on the side wall of the combustion chamber and is connected to the blower 9.

When the burner 3 is ignited, the flame 5 is supplied into the radiation chamber, the radiation cylinder 2 is heated, and the radiant heat 6 is released into the drying chamber 1, whereby the burned object is heated to an oxygen-free state. Dry distillation and gasification generate | occur | produce dry gas (11). The generated dry gas 11 is sucked into the combustion chamber 7 through the dry gas discharge port 8 by the draft action of the exhaust cylinder, and is discharged from the flame 5 and the blower 9 supplied from the outlet 2B of the radiation cylinder. It is mixed with the combustion air 12 supplied through the air inlet 14, and fully reacts with the air while turning downward while turning. The clean and harmless exhaust gas 13 generated by this combustion is discharged out of the furnace from the exhaust cylinder 50.

Since the radiator is disposed in the lower part of the distillation chamber in the longitudinal length, even if the burned-up material is reduced in volume after the start of distillation, the radiant heat can be supplied from the inside of the deposit, so that it can be dried and gasified more efficiently. In addition, since the distillation chamber and the combustion chamber integrate a part of the sidewalls, heat generated by the combustion of the dry gas in the combustion chamber is transferred to the distillation chamber through the integrated sidewalls, whereby higher distillation efficiency can be obtained. Even if dust is generated in the drying chamber and enters the combustion chamber by the flow of dry gas, it is separated by the cyclone action and remains at the bottom of the combustion chamber so that it does not leak out of the furnace.

(4) Fig. 4 is a schematic side cross-sectional view (a) and a schematic planar cross-sectional view (b) showing an embodiment (Example 4) of a type C incinerator of the present invention.

The generated dry gas 11 passes through the dry gas gas outlet 8 by the draft action of the exhaust cylinder, is sucked in the vicinity of the radiant outlet of the combustion cylinder 4 and the vicinity of the air inlet, and is supplied from the outlet 2B of the radiant cylinder. The flame 5 and the blower 9 rapidly mix with the combustion air 12 supplied through the air inlet 14 to burn almost completely. The clean and harmless exhaust gas 13 generated by this combustion is discharged out of the furnace from the exhaust cylinder 50.

Since the radiator is disposed in the lower part of the distillation chamber in the lateral length, even if the burned-up material is reduced in volume after the start of distillation, the radiant heat can be supplied from the inside of the sediment, so that it can be dried and gasified more efficiently. Moreover, since the combustion cylinder is closely arranged on the side wall of the distillation chamber, the structure is very simple and heat generated by the combustion of the dry gas in the combustion vessel is effectively transferred in the distillation chamber, and the distillation efficiency is further increased.

(6) Fig. 6 is a schematic side cross-sectional view showing an embodiment (Example 6) of the type B incinerator B1 of the present invention. In the present embodiment, the radiation container 2 is moved from the outside of the distillation chamber 1 containing the small object (not shown) to an almost center position in the room height direction along the inner bottom (below the road grid 17). It stands up and the outdoor radiation cylinder inlet 2A is connected with the burner 3. As shown in FIG. The radiant cylinder outlet 2B in the room is in contact with the inlet of the combustion cylinder 4, and a dry gas outlet 8 is formed at this junction. The air inlet 14 is located near the combustion cylinder inlet and is connected to the blower 9 in the air flow passage 15. A part of the air flow path 15 follows a combustion cylinder using a double pipe structure. The exhaust cylinder 50 is connected to the outlet of the combustion cylinder 7.

When the burner 3 is ignited, the flame 5 is supplied into the radiation chamber, the radiation cylinder 2 is heated, and the radiant heat 6 is discharged into the drying chamber 1, whereby the burned object is heated to an oxygen-free state. Dry distillation and gasification generate | occur | produce dry gas (11). The generated dry gas 11 passes through the dry gas gas outlet 8 by the draft action of the exhaust cylinder, is sucked in the vicinity of the radiant outlet of the combustion cylinder 4 and the vicinity of the air inlet, and is supplied from the outlet 2B of the radiant cylinder. It is rapidly mixed with the flame 5 and the combustion air 12 supplied from the blower 9 through the air inlet 14 to burn almost completely. The clean and harmless exhaust gas 13 generated by this combustion is discharged out of the furnace from the exhaust cylinder 50.

Since the radiant heat 6 is supplied not only at the standing portion of the copying box but also at the bottom extension part (that is, the effective reach of the radiant heat is extended), the efficiency of carbonization is higher than in the case of a copying box having a simple longitudinal length arrangement. In addition, in this example, a part of the air passage is along the combustion cylinder to cool the combustion cylinder, but the present invention is not limited thereto.

In addition, in the present embodiment, although the inverted T-shaped tubular body as shown in the figure shows that the copy tube stands up from the outside of the distillation chamber to a predetermined height position along the inner bottom, the present invention is here. It is not limited, For example, the tube uses a tube such as an inverted V-shape (A type) or an inverted Y-shape so that the copy tube enters the bottom of the interior from the outside of the distillation chamber, and passes through the inclination upwards, for example, to reach a predetermined height position therein. It may be one. Even in this form, the effective reach of the radiant heat can be extended to obtain the same effect.

As shown in FIG. Each radiation cylinder outlet 2B in the room is connected to the inlet of the combustion cylinder 4, respectively, and a dry gas outlet 8 is formed at this junction. The air inlet 14 is located near the combustion cylinder inlet and is connected to the blower 9 in the air flow passage 15. A part of the air flow path 15 uses a double pipe structure to follow the combustion cylinder. The exhaust cylinder 50 is connected to the outlet of the combustion cylinder 7.

When the burner 3 is ignited, the flame 5 is supplied into the radiation chamber, the radiation cylinder 2 is heated, and the radiant heat 6 is discharged into the drying chamber 1, whereby the burned object is heated to an oxygen-free state. Dry distillation and gasification generate | occur | produce dry gas (11). The generated dry gas is sucked by the draft action of the exhaust cylinder into the vicinity of the radiant outlet of the combustion cylinder 4 and the vicinity of the air inlet through the distillate gas outlet 8, and the flame 5 supplied from the outlet 2B of the radiant cylinder. , And rapidly mix with the combustion air 12 supplied from the blower 9 through the air inlet 14 to burn almost completely. The clean and harmless exhaust gas 13 generated by this combustion is discharged out of the furnace from the exhaust cylinder 50.

Since the radiant heat 6 is supplied from two radiation cylinders arrange | positioned at another part, dry distillation and gasification are accelerated | stimulated further. In this example, a part of the air flow path is provided along the combustion cylinder to cool the combustion cylinder, but the present invention is not limited thereto. In addition, in this example, one exhaust cylinder is connected to each combustion cylinder. However, it is possible to provide a collective chimney type exhaust cylinder in which the outlets are collected in one.

According to the present invention, a dry distillation incinerator having high dry distillation and combustion efficiency, very simple furnace structure, and excellent operability and maintainability can be realized.
