[Purpose of the invention] Industrial application field This invention is a method for processing pyrolysis gas in a smoldering furnace that efficiently burns pyrolysis gas discharged from a smoldering furnace that performs the smoking process for smoking roof tiles, etc. It is related to the device. Conventional technology To manufacture smoked tiles using a smoked tile firing furnace, as an example of a smoking operation, the tiles are usually fired with an oxidizing flame to a temperature of 1,000 to 1,100°C, and then an exhaust hole for pyrolysis gas is provided in the flue leading to the chimney. With a damper attached and all openings of the firing furnace other than the discharge hole sealed, the furnace is cooled to approximately 900°C, which is the optimum temperature for smoking, and at this point a smoking agent such as LPG is introduced into the furnace. Smoked tiles are produced by catalytically decomposing a smoking agent that has been converted into hydrocarbons through high-temperature pyrolysis onto a hot tile base, and depositing carbon on the surface of the base. And the injection of fumigating agent is usually carried out for 30 to 60 minutes,
During this time, the pyrolysis gas is released into the atmosphere from the chimney through the exhaust hole, but this pyrolysis gas is odorous and contains a large amount of solid carbon (soot), causing many pollution problems. Conventionally, therefore, a simple igniter was installed near the outlet of the exhaust hole to ignite and burn the exhausted pyrolysis gas. Problems to be Solved by the Invention However, although the conventional treatment methods can relatively easily decompose odorous gases, they have not been sufficiently effective in burning solid carbon. This is because solid carbon itself is difficult to burn, and pyrolysis gas is emitted from the exhaust hole at a very high velocity of around 50 m/sec, so even if it ignites, it is emitted from the chimney without being fully combusted. To solve this problem, it is necessary to provide sufficient time and temperature for combustion, and this has the disadvantage of requiring a long chimney, resulting in a tall chimney, resulting in very high equipment costs. [Structure of the invention] Means for solving the problems In view of the above drawbacks, the present invention has a method in which pyrolysis gas generated during the smoking process is introduced into one chimney of a firing furnace that has a process of smoking tiles, etc. A combustion air introduction pipe into which combustion air is introduced is arranged on the outer periphery of the exhaust gas pipe, and a combustion air introduction pipe into which combustion air is introduced is arranged on the circumference of the exhaust gas pipe, and a combustion air introduction pipe into which combustion air is introduced into the combustion air introduction pipe is introduced into the exhaust gas pipe. A combustion air mixing tube is formed by a combustion air introduction tube and an exhaust tube by penetrating a large number of injection holes for injecting the air into the combustion air, and a combustion air mixing tube is fitted onto the outer periphery of the combustion air introduction tube in the upper part of the combustion air mixing tube. A combustion tube which is heated by a burner is formed, and a combustion part is removably arranged around the outer periphery of the combustion tube, in which an exterior tube is integrally arranged concentrically with a predetermined interval. The chimney of the other firing furnace having the smoking process is connected to the chimney by a horizontal flue, and the horizontal flue is provided with a second processing device having a heating device. It is an object of the present invention to provide a treatment apparatus for pyrolysis gas in order to overcome the above-mentioned drawbacks. Effect: By the above means, the pyrolysis gas is introduced into the exhaust gas cylinder and while it rises, combustion air is injected and supplied in a strong swirling state from the combustion air introduction cylinder through the injection hole.
It is mixed with pyrolysis gas in the exhaust gas cylinder and reaches the upper combustion cylinder, where it comes into contact with the combustion cylinder which has been made red hot by a burner and is combusted.The pyrolysis gas is then sent to another chimney through a horizontal flue. It is made to flow in through the air and be released into the atmosphere. In this process, the material reaches a second processing device in the side flue, where it comes into contact with a heating member heated to a predetermined temperature and is burned again, and is released into the atmosphere through the chimney with an extremely low solid carbon content. It will be done. Embodiment An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 denotes a first treatment device for pyrolysis gas, and one chimney 3 is installed in communication with an exhaust port 2 of a firing furnace.
A smoking damper 4 that opens and closes the exhaust port 2 is removably attached to the lower part of the interior through a working hole 5, and a central part of the smoking damper 4 discharges pyrolysis gas into the chimney 3. Discharge hole 6
(usually φ30 to 50 mm). Reference numeral 7 denotes a combustion air mixing cylinder disposed above the smoking damper 4, and an exhaust gas cylinder 8 is installed upright so as to communicate with the exhaust hole 6, and a predetermined interval is provided around the outer circumference of the exhaust gas cylinder 8. At least the combustion air introduction tube 9 is arranged concentrically, and a sealed air introduction chamber 10 is formed between the combustion air introduction tube 9 and the exhaust gas tube 8, and a blower or the like is installed in the air introduction chamber 10. An air supply pipe 11 through which combustion air is forcibly introduced from the outside is introduced via a valve 12,
In addition, an air jetting part 13 having a slightly larger diameter is formed in the upper part of the exhaust gas pipe 8, and the air introducing chamber 10 is connected to the exhaust gas pipe 8 by extending around the entire circumference of the air jetting part 13.
A large number of injection holes 14, 14a, . . . are provided therethrough and communicate with each other. Reference numeral 15 denotes a combustion section that is detachably disposed above the combustion air mixing tube 7 and communicates with the exhaust gas tube 8. At the same time, an outer cylinder 17 is integrally arranged at a concentric position with a predetermined interval on the outer periphery of the combustion cylinder 16. is attached to heat the combustion tube 16. Reference numerals 19, 19a, . . . are jet holes through which the flame of the burner 18 is ejected, 20, 20a, . Then, as shown in Fig. 3, the chimney 3a of another kiln
A horizontal flue 22 is installed between the chimney 3a and the chimney 3 to communicate with each other, and a second processing device 23 is installed in the middle of the horizontal flue 22, that is, in a lattice shape. The heating member 24 made of assembled bricks is placed in an intervening position, and the heating member 2
A heating device 26 is installed to heat and burn the pyrolysis gas passing through the horizontal flue 22 by installing a burner 25 that heats the duct 4 to a predetermined temperature. Note that 21a is a chimney damper installed in the chimney 3a. Next, to explain the operation of the pyrolysis gas processing device in the smoldering and firing furnace according to the present invention, firstly, regarding the first processing device 1 of one chimney 3, the firing furnace is loaded with a trolley loaded with tile blanks. is heated by a firing burner and raised to a maximum firing temperature of 1000 to 1100°C, during which combustion gas is discharged from the furnace through the flue and into the atmosphere through the chimney 3. After firing, the firing burner is extinguished, the smoking damper 4 is installed between the flue and the chimney 3, and the other openings of the firing furnace are sealed, leaving only the exhaust hole 6 of the smoking damper 4 inside the furnace. to communicate with the outside. Under these conditions, the temperature inside the furnace is about the appropriate temperature for smoking.
While being cooled to 900°C, the combustion air mixing cylinder 7 and the combustion cylinder 16 are installed on the smoking damper 4 so as to communicate with the exhaust hole 6, and the combustion cylinder 16 is heated to a red-hot state by the burner 18. Let it heat up. The fumigation operation is carried out by injecting the fumigating agent into the furnace from a number of fumigating agent injection nozzles installed on the furnace wall of the kiln. Immediately after the fumigating agent is introduced, pyrolysis gas is ejected from the exhaust hole 6. Therefore, combustion air is introduced into the combustion air introduction tube 9 using a blower or the like at the same time as or a little before the smoldering. The introduced combustion air becomes a swirling flow in the combustion air introduction tube 9 and is ejected into the exhaust gas tube 8 from the injection holes 14, 14a... provided through the air jetting part 13 of the exhaust gas tube 8, and is converted into pyrolysis gas. The mixture is well mixed and introduced into the upper combustion tube 16. Since the combustion tube 16 has already been made red hot by the burner 18, the pyrolysis gas mixed with combustion air is ignited and burned in the combustion tube 16, and the solid carbon content in the pyrolysis gas is efficiently combusted and sent to the chimney 3. It is released into the atmosphere. In addition, it is desirable to adjust the amount of combustion air to be mixed to the optimum combustion state in accordance with the amount of smoker added, and this may be automatically controlled depending on the amount of smoker. In the case of a mixture, the amount of combustion air may be controlled by proportionally controlling the flow rate of the combustion air to be mixed in response to fluctuations in the pressure or flow rate supplied into the furnace. The above is an arrangement in which the pyrolysis gas is processed only by the first processing device 1;
Processing equipment 1 can be expected to have a great effect on relatively low-capacity kilns that can fire around 1,000 tiles at a time, but recently, high-capacity kilns that can fire around 4,000 tiles at a time are being used. Furnaces are also being used, and the amount of fumigating agent used in such large-capacity kilning furnaces is also increasing, but pyrolysis gas discharge holes 6 are still used with diameters of around 30 to 50 mm. Because of this, the ejection speed of the pyrolysis gas is about 2 to 3 times higher, and in this case, the processing capacity of the first processing device 1 alone will naturally be poor, and even a firing furnace with a small capacity will have more problems due to pollution, etc. There may also be cases that require complete treatment. Therefore, regarding the second processing device 23 interposed between the other chimney 3a and one chimney 3 in order to cope with such a request, the chimney of the chimney 3 in the firing furnace where the smoking and firing will be performed before the temperature rise starts. damper 2
1 is closed so that exhaust gas and pyrolysis gas flow into the horizontal flue 22 and are discharged into the atmosphere through the chimney 3a of another kiln. Then, as the exhaust gas whose temperature is rising passes through the horizontal flue 22, the temperature of the heating member 24 disposed in the horizontal flue 22 is gradually raised, and at the start of smoking, the heating member 24 is heated by the burner 25 to 600 to 1000 ℃. Heat it to a high temperature around ℃. When smoking starts in such a state, pyrolysis gas flows in from the exhaust hole 6, is combusted in the first processing device 1 as described above, and reaches the second processing device 23 in the horizontal flue 22. When it comes into contact with the heating member 24 heated to a predetermined temperature, it is burned again and is released into the atmosphere through the chimney 3a with an extremely low solid carbon content. Below, actual measured values are shown when pyrolysis gas is processed by the pyrolysis gas processing device in the smoldering furnace according to the present invention. Fumigation was carried out for 50 minutes using LPG as a fumigating agent. The amount of LPG used is usually indicated by the pressure of the gas supplied into the furnace, and as shown in Figure 4, the amount of LPG used is 200% for the first 5 minutes.

In short, the present invention disposes an exhaust gas cylinder 8 into which pyrolysis gas generated during the smoking process is introduced into one chimney 3 of a firing furnace that performs the process of smoking tiles, etc.
A combustion air introduction pipe 9 into which combustion air is introduced is disposed on the outer periphery of the exhaust gas pipe 8, and a combustion air introducing pipe 9 introduced into the combustion air introduction pipe 9 is injected into the exhaust gas pipe 8 on the circumferential surface of the exhaust gas pipe 8. A large number of injection holes 14, 1
Since the combustion air mixing cylinder 7 is constituted by the combustion air introduction cylinder 9 and the exhaust gas cylinder 8 by penetrating the combustion air cylinder 4a,
By injecting combustion air into the pyrolysis gas containing a large amount of solid carbon in a swirling manner, the solid carbon can be scattered and the combustion air can be mixed efficiently. A combustion tube 16 is formed to be heated by a burner 18 so as to fit around the outer periphery of the combustion air introduction tube 9, and an exterior tube 17 is formed at a predetermined interval on the outer periphery of the combustion tube 16. Since the combustion part 15 is arranged concentrically and integrally in a removable manner, the pyrolysis gas mixed with combustion air in the combustion air mixing cylinder 7 is heated to red heat by the burner 18, and the combustion part 15 is removably arranged. By making the combustion tube 16 come into contact with the combustion tube 16, it is possible to efficiently perform the combustion process and prevent air pollution due to the release of soot and dust, and since the combustion tube 16 is arranged in a detachable manner, the workability when replacing the combustion tube 16 is improved. It is possible to force it. Also, the chimney 3a of the other firing furnace having the smoking process
and the chimney 3 are communicated through a horizontal flue 22, and a second processing device 23 having a heating device 26 is provided in the horizontal flue 22, so that the heat generated by the combustion process in the first processing device 1 is The cracked gas is transferred to the second processing device 2.
By carrying out combustion treatment again in step 3, the concentration of soot and dust in the emitted exhaust gas can be further reduced. 3a can be used effectively, it can be manufactured at a very low cost compared to a structure in which a second treatment device 23 is added on the same chimney, and maintenance can be easily performed. Two or more kilns for firing tiles, etc. are installed, and when one kiln starts the cooling process, the other kilns are ignited and the temperature is increased, which is effective for most kilns. Its practical effects are enormous, such as the fact that it can be applied to many situations.
