Background Art

[0002] Conventionally, from the viewpoint of environmental sanitation, Ammonia odor gas containing has been decomposed and treated.

[0003] In Patent Document 1, a gas to be treated containing ammonia is decomposed in an ammonia decomposition chamber by heat from an electric heater, and the gas to be treated containing nitrogen and hydrogen generated by the decomposition is led into a pyrolysis gas combustion chamber. At the same time, air is supplied into the pyrolysis gas combustion chamber so that the hydrogen is burned in the pyrolysis gas combustion chamber.

[0004] However, in the device disclosed in Patent Document 1, an ammonia decomposition chamber for thermally decomposing a gas to be treated containing ammonia by an electric heater is required, which increases the size of the device, resulting in high equipment costs and high running costs.

[0005] Patent Document 2 discloses a regenerative combustion deodorization device that includes a combustion chamber equipped with a burner, three or more heat storage chambers each equipped with a heat storage body and communicating with the combustion chamber, a supply flow path equipped with a fan and supplying raw gas to the combustion chamber through one of the heat storage chambers, an exhaust flow path exhausting treated gas from the combustion chamber through one of the heat storage chambers, a purge flow path extracting treated gas from the combustion chamber through one of the heat storage chambers and circulating it upstream of the fan in the supply flow path, and an adjustment damper disposed in the exhaust flow path or upstream of the junction of the supply flow path with the purge flow path, and that controls the opening of the adjustment damper to adjust the flow path resistance of the exhaust flow path or upstream of the junction of the supply flow path with the purge flow path, thereby maintaining a constant gas flow rate in the purge flow path.

[0006] However, even with the device disclosed in Patent Document 2, there are problems in that the entire device becomes very large, resulting in very high equipment costs and high running costs.

[0008] However, even with the device shown in Patent Document 3, the entire device is long in the horizontal direction, which requires a long space in the horizontal direction and results in high equipment costs. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] WO2012 / 120773 publication [Patent Document 2] Patent No. 5468359 [Patent Document 3] Patent No. 5878587 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0010] The present invention provides ammonia The present invention aims to solve the above-mentioned problems in an apparatus for decomposing and treating odorous gases containing benzophenone.

[0011] That is, the present invention is ammonia The present invention addresses the problem of enabling an apparatus for decomposing and treating odorous gases containing benzophenone-3, benzophenone-4, benzotriazole ... [Means for solving the problem]

[0012] In order to solve the above-mentioned problems, the odorous gas treatment device of the present invention has the following features: Contains ammonia A combustion chamber in which odorous gas is thermally decomposed by combustion with a burner, and a heat storage device provided below the combustion chamber, which stores the heat of the first decomposed gas thermally decomposed in the combustion chamber in a heat storage material and stores the heat stored in the heat storage material to decompose the odorous gas remaining in the first decomposed gas. The aforementioned a heat storage chamber for thermally decomposing odorous gases; The aforementioned The apparatus is provided with an exhaust section for exhausting the second decomposition gas produced after the odorous gas has been thermally decomposed.

[0013] In the odorous gas treatment device of the present invention, in the combustion chamber, Contains ammonia The odorous gas is decomposed by heating using a burner and then burned in a combustion chamber. The aforementioned The first decomposition gas of the odorous gas is led to the heat storage chamber installed under the combustion chamber, and is then heated by the heat storage material in the heat storage chamber. The aforementioned The heat in the first decomposition gas of the odorous gas is stored, and the heat stored in the heat storage material is used to heat the gas remaining in the first decomposition gas. The aforementioned When odorous gases are decomposed, The aforementionedDecomposition of odorous gases can be completed in a short time, and the combustion chamber can be shortened (reduced in height), so the device does not have to be large as in the past. The aforementioned This allows for efficient decomposition and treatment of odorous gases. In particular, the height of the combustion chamber can be reduced, allowing it to be installed in factory buildings with low ceilings.

[0014] Here, the odorous gas treatment device of the present invention As mentioned above, the odorous gases in Treating odorous gases containing ammonia I try to .

[0015] Furthermore, in the odorous gas treatment device of the present invention, a control device is provided for controlling the flow rates of fuel and combustion air supplied to a burner provided in the combustion chamber, and a temperature detection device is provided for detecting the temperature of the second decomposition gas exhausted from the exhaust section, and the flow rates of fuel and combustion air supplied to the burner can be controlled by the control device based on the temperature of the second decomposition gas detected by the temperature detection device.

[0016] When the temperature of the second decomposition gas discharged from the exhaust section detected by the temperature detection device is low, the control device increases the flow rates of fuel and air supplied to the burner, while when the temperature of the second decomposition gas discharged from the exhaust section is high, the control device decreases the flow rates of fuel and air supplied to the burner.

[0017] When the temperature of the second decomposition gas exhausted from the exhaust section is low, increasing the flow rates of the fuel and air supplied to the burner raises the temperature of the odor gas that is burned and decomposed in the combustion chamber, promoting the decomposition of the odor gas. At the same time, the temperature of the first decomposition gas led to the heat storage chamber increases, increasing the heat stored in the heat storage material in the heat storage chamber. The odor gas remaining in the first decomposition gas is decomposed more efficiently by the heat stored in the heat storage material. On the other hand, when the temperature of the second decomposition gas exhausted from the exhaust section is high, even if the flow rates of the fuel and air supplied to the burner are reduced, the temperature of the heat storage material in the combustion chamber and the heat storage chamber is high. Therefore, the odor gas can be appropriately burned and decomposed in the combustion chamber, and the odor gas remaining in the first decomposition gas can be decomposed by the heat stored in the heat storage material, eliminating the need to use more fuel than necessary. At the same time, the temperature of the second decomposition gas exhausted from the exhaust section decreases, protecting the cooling device that cools the second decomposition gas. When the concentration of the odor gas in the combustion chamber becomes too high, the fuel supply can also be stopped.

[0018] Here, As mentioned above When using an odor gas containing ammonia, the hydrogen contained in the odor gas remaining in the first decomposition gas is burned and consumed by the heat stored in the heat storage material, and the heat generated by this combustion is stored in the heat storage material. This enables the safe exhaust of the second decomposition gas and The aforementioned effectively utilizes the hydrogen contained in the odor gas.

[0019] In addition, in the odorous gas treatment device of the present invention, the heat storage chamber is provided laterally from below the combustion chamber, the exhaust section is provided at a position of the heat storage chamber away from the combustion chamber, and a suppression section is provided at the boundary between the combustion chamber and the heat storage chamber near the exhaust section to suppress the first decomposition gas of the odorous gas burned in the combustion chamber from flowing into the heat storage chamber, so that the first decomposition gas can be led to the heat storage chamber from a position away from the exhaust section. In this way, the first decomposition gas of the odorous gas that has been heated and decomposed by combustion in the combustion chamber is prevented from flowing into the heat storage chamber from the boundary between the combustion chamber and the heat storage chamber, which is close to the exhaust section, and the prevention section provided at the boundary allows the first decomposition gas of the odorous gas to be introduced into the heat storage chamber from a position away from the exhaust section and guided to the exhaust section, so that the heat in the first decomposition gas of the odorous gas is efficiently stored in the entire heat storage material in the heat storage chamber, and the odorous gas remaining in the first decomposition gas is more efficiently decomposed by the heat stored in the heat storage material in the heat storage chamber. Effect of the Invention

[0020] In the odorous gas treatment device according to the present invention, as described above, Contains ammonia The odorous gas is decomposed by heating in the combustion chamber by a burner, and the gas is decomposed by heating in the combustion chamber. The aforementioned The first decomposition gas of the odorous gas is introduced into a heat storage chamber provided below the combustion chamber, and the heat in the first decomposition gas is stored in a heat storage material in the heat storage chamber, and the heat stored in the heat storage material is used to convert the heat remaining in the first decomposition gas into heat. The aforementioned Decomposes odorous gases, The aforementioned After the odorous gas is decomposed, the second decomposition gas is exhausted from the exhaust section.

[0021] As a result, the odorous gas treatment device of the present invention does not become large in size. Contains ammonia It has become possible to efficiently decompose and treat odorous gases. [Brief description of the drawings]

BEST MODE FOR CARRYING OUT THE INVENTION

[0023] The odorous gas treatment device according to the embodiment of the present invention will be specifically described below with reference to the accompanying drawings. Note that the odorous gas treatment device according to the present invention is not limited to the embodiment shown below, and can be appropriately modified and implemented within the scope of the invention.

[0024] In the odorous gas treatment apparatus according to the embodiment, as shown in FIGS. 1 and 2, an odorous gas Gn containing ammonia NH3 is introduced into the combustion chamber 10 from an introduction part 11 provided at the top of the combustion chamber 10, and the odorous gas Gn is burned by each burner 12 provided in the combustion chamber 10, so that the ammonia NH3 contained in the odorous gas Gn is burned and thermally decomposed into hydrogen H2 and nitrogen N2, and the first decomposition gas Gn1 of the burned odorous gas Gn is discharged into the combustion chamber 10. The decomposed gas Gn1 is led into a heat storage chamber 20 provided horizontally below the decomposed gas storage chamber 10, and the heat of the first decomposed gas Gn1 is stored in a heat storage material 21 contained in the heat storage chamber 20, and the odorous gas Gn remaining in the first decomposed gas Gn1 is thermally decomposed by the heat stored in the heat storage material 21. The second decomposed gas Gn2 obtained after the odorous gas Gn remaining in the first decomposed gas Gn1 has been decomposed in the heat storage chamber 20 is exhausted through an exhaust part 22 provided horizontally. In this way, the height of the entire odorous gas treatment apparatus can be made lower than when the heat storage chamber is provided vertically and the exhaust part is provided below the heat storage chamber as in the conventional case, and the apparatus can be installed in a factory building with a low ceiling.

[0025] And in the odor gas treatment apparatus according to the embodiment, the temperature of the second decomposition gas Gn2 exhausted through the exhaust part 22 as described above is detected by the temperature detection device 31, and the temperature of the second decomposition gas Gn2 detected by this temperature detection device 31 is output to the control device 30.

[0026] Also, in this embodiment, in order to prevent the heat storage material 21 accommodated in the heat storage chamber 20 from spilling out to the exhaust part 22, a grating 23 is provided between the heat storage chamber 20 and the exhaust part 22.

[0027] Here, in the odor gas treatment apparatus according to this embodiment, when burning and thermally decomposing the odor gas Gn by each burner 12 provided in the combustion chamber 10 as described above, a flow rate adjustment valve 13a is provided in each fuel supply pipe 13 that supplies the fuel gas Ga to each burner 12, and a flow rate adjustment valve 14a is provided in each air supply pipe 14 that supplies the combustion air Air to each burner 12.

[0028] Then, the temperature of the second decomposition gas Gn2 exhausted from the inside of the heat storage chamber 20 through the exhaust part 22 is detected by the temperature detection device 31, and based on the temperature of the second decomposition gas Gn2 detected by this temperature detection device 31, the control device 30 adjusts the flow rate adjustment valve 13a provided in each fuel supply pipe 13 to adjust the amount of fuel gas Ga supplied to each burner 12, and adjusts the flow rate adjustment valve 14a provided in each of the above air supply pipes 14 to adjust the combustion air Air supplied to each burner 12.

[0029] Here, when the temperature of the second decomposition gas Gn2 detected by the temperature detection device 31 does not reach a predetermined temperature, for example, 800°C at which the thermal decomposition of the second decomposition gas Gn2 becomes difficult, as shown in FIG. 1, the control device 30 adjusts the flow rate adjustment valve 13a provided in each fuel supply pipe 13 to adjust the amount of fuel gas Ga supplied to each burner 12. At the same time, the flow rate adjustment valve 14a provided in each air supply pipe 14 is adjusted to adjust the combustion air Air supplied to each burner 12. In each burner 12, the fuel gas Ga and the combustion air Air are mixed and burned, and the odor gas Gn containing ammonia NH3 introduced into the combustion chamber 10 from the introduction part 11 as described above is heated in the combustion chamber 10 so that the ammonia NH3 contained in the odor gas Gn is decomposed into hydrogen H2 and nitrogen N2.

[0030] Then, the first decomposition gas Gn1 of the odor gas Gn burned in this way is introduced into the heat storage chamber 20, and the heat of the first decomposition gas Gn1 is stored in the heat storage material 21 accommodated in the heat storage chamber 20. At the same time, the odor gas Gn remaining in the first decomposition gas Gn1 is thermally decomposed by the heat stored in the heat storage material 21.

[0031] On the other hand, when the temperature of the second decomposition gas Gn2 detected by the temperature detection device 31 reaches 800°C or more of the predetermined temperature and the temperature in the combustion chamber 10 reaches a temperature at which the odor gas Gn containing ammonia NH3 can be thermally decomposed, the control device 30 reduces the flow rates of the fuel gas Ga and the combustion air Air supplied to each burner 12 to control the temperature in the combustion chamber 10 to be maintained.

[0032] 2, when the temperature inside the combustion chamber 10 becomes too high, the control device 30 closes the flow rate control valves 13a provided in the fuel supply pipes 13 to prevent the supply of fuel gas Ga to the burners 12, and furthermore, in order to suppress an increase in the temperature inside the combustion chamber 10, only combustion air Air is supplied from the air supply pipes 14 to the burners 12, so that the odorous gas Gn containing ammonia NH3 introduced into the combustion chamber 10 from the introduction part 11 is burned and thermally decomposed inside the combustion chamber 10. Note that the flow rate control valves 13a and 14a are shown as open when open and as filled in when closed.

[0033] Then, when the first decomposition gas Gn1 of the odorous gas Gn thus burned and thermally decomposed is introduced into the heat storage chamber 20, the odorous gas Gn remaining in the first decomposition gas Gn1 is sufficiently thermally decomposed by the heat stored in the heat storage material 21 which is heated to a high temperature while being contained in the heat storage chamber 20. Note that a combustion chamber temperature sensor (not shown) for detecting the temperature inside the combustion chamber 10 may be provided to detect whether the temperature inside the combustion chamber 10 has reached the combustion temperature at which the odorous gas Gn containing ammonia NH3 is combusted.

[0034] In this way, the amount of fuel gas Ga supplied to each burner 12 can be reduced, thereby reducing fuel costs, and the temperature of the second decomposition gas Gn2 exhausted through the exhaust section 22 can be prevented from becoming higher than necessary, thereby protecting the cooling device (not shown) that cools the second decomposition gas Gn2 exhausted through the exhaust section 22.

[0035] Furthermore, when an odorous gas Gn containing ammonia NH3 is used as the odorous gas Gn as described above, the hydrogen H2 contained in the odorous gas Gn remaining in the first decomposition gas Gn1 is burned and consumed by the heat stored in the heat storage material 21, and the heat from this combustion is stored in the heat storage material 21, making it possible to safely exhaust the second decomposition gas Gn2 and effectively utilize the hydrogen H2 contained in the odorous gas Gn.

[0036] Also, in the odor gas treatment apparatus according to this embodiment, when burning the odor gas Gn with each burner 12 provided in the combustion chamber 10 as described above, as shown in FIG. 3, the combustion chamber 10 is formed in a cylindrical shape, and the fuel gas Ga and the combustion air Air are injected from each burner 12 in the tangential direction on the inner peripheral side of the combustion chamber 10, so that the odor gas Gn introduced into the combustion chamber 10 from the introduction part 11 is swirled in the combustion chamber 10 and burned. This is preferable. By doing so, the odor gas Gn introduced into the combustion chamber 10 is burned while being sufficiently stirred in the combustion chamber 10, the odor gas Gn is quickly burned and decomposed, and the height of the combustion chamber 10 can be reduced.

[0037] Also, in the odor gas treatment apparatus according to this embodiment, as shown in FIGS. 4 and 5, in order to suppress the first decomposition gas Gn1 of the odor gas Gn burned in the combustion chamber 10 from flowing into the heat storage chamber 20 from the combustion chamber 10 at a position close to the exhaust part 22 and being immediately guided to and discharged from the exhaust part 22, at the boundary part between the combustion chamber 10 and the heat storage chamber 20 close to the exhaust part 22, as a suppression part 40 for suppressing the first decomposition gas Gn1 from being guided to the heat storage chamber 20, a semicircular suppression plate 41 is provided so as to protrude toward the center part, and the first decomposition gas Gn1 can be guided to the heat storage chamber 20 through a communication part 50 away from the exhaust part 22 where the suppression plate 41 is not provided.

[0038] By doing so, the first decomposition gas Gn1 is introduced into the heat storage chamber 20 from a position away from the exhaust part 22 through the communication part 50 and guided to the exhaust part 22. The heat of the first decomposition gas Gn1 is efficiently stored in the entire heat storage material 21 in the heat storage chamber 20, and the odor gas Gn remaining in the first decomposition gas Gn1 is more efficiently decomposed by the heat stored in the heat storage material 21 in the heat storage chamber 20.

[0039] In addition, in the odor gas treatment apparatus shown in FIG. 4, in order to prevent the heat storage material 21 accommodated in the heat storage chamber 20 from spilling out into the exhaust section 22, instead of the grating 23 described above, a plurality of inclined plates 24 inclined upward with respect to the exhaust direction are provided at a required interval in the vertical direction.

[0040] Further, in the odor gas treatment apparatus according to this embodiment, in order to suppress the first decomposition gas Gn1 of the odor gas Gn burned in the combustion chamber 10 from flowing from the combustion chamber 10 to the heat storage chamber 20 at a position close to the exhaust section 22 and being immediately guided to the exhaust section 22, when providing the suppressing portion 40 at the boundary portion between the combustion chamber 10 and the heat storage chamber 20 close to the exhaust section 22, for example, as shown in FIG. 6, a suppressing plate 42 having an arc shape such that both sides are away from the exhaust section 22 so that the area is larger than the semi-circular shape is provided, and the first decomposition gas Gn1 is guided from a position away from the exhaust section 22 through the communication portion 50 to the heat storage chamber 20, or as shown in FIG. 7, a plurality of communication portions 50 having different circular shapes are provided on a suppressing plate 43 formed on a disc that closes the boundary portion between the combustion chamber 10 and the heat storage chamber 20, and the diameter of the circular communication portion 50 is made larger as it is away from the exhaust section 22.

[0041] And even when configured as shown in FIGS. 6 and 7, the first decomposition gas Gn1 of the odor gas Gn is introduced into the heat storage chamber 20 from a position away from the exhaust section 22 through the communication portion 50 and then guided to the exhaust section 22 as described above. The heat of the first decomposition gas Gn1 is efficiently stored in the entire heat storage material 21 in the heat storage chamber 20, and the odor gas Gn remaining in the first decomposition gas Gn1 is more efficiently decomposed by the heat stored in the heat storage material 21 in the heat storage chamber 20.

[0042] Also, in the odor gas treatment apparatus according to this embodiment, when the suppression unit 40 suppresses the first decomposition gas Gn1 from flowing into the heat storage chamber 20 at a position close to the exhaust unit 22 from the combustion chamber 10 and being immediately guided to the exhaust unit 22 as described above, as shown in FIG. 8, at the boundary portion between the combustion chamber 10 and the heat storage chamber 20 close to the exhaust unit 22, a suppression member 44 is provided such that the upper surface 44a inclines downward toward the center portion from the combustion chamber 10 toward the heat storage chamber 20 side, and the first decomposition gas Gn1 of the odor gas Gn can be guided to the communication unit 50 along the upper surface 44a of the suppression member 44 and introduced into the heat storage chamber 20.

[0043] Also, as shown in FIG. 8, in the heat storage chamber 20, an inclined guide portion 51 is provided at the lower corner portion away from the exhaust unit 22 to reduce the flow resistance of the bent portion, and the first decomposition gas Gn1 introduced into the heat storage chamber 20 from the communication unit 50 away from the exhaust unit 22 as described above can be guided by the guide portion 51 and led to the exhaust unit 22 through the heat storage material 21 accommodated in the heat storage chamber 20.
