Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to a three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure. Background Technology

[0002] Regenerative Thermal Oxidizers (RTOs) heat the organic waste gas discharged from production processes through regenerative ceramic chambers, rapidly raising its temperature to 680–1050°C under the heating effect of combustion gas within the furnace. At this high temperature, VOCs in the waste gas directly decompose into carbon dioxide and water vapor, forming odorless, high-temperature flue gas. This flue gas then flows through the cooler regenerative ceramic chambers, where a significant amount of heat energy is transferred to the regenerative chamber to heat the next cycle of organic waste gas to be decomposed. The high-temperature flue gas itself experiences a substantial temperature drop, and after passing through a heat recovery system and other media for heat exchange, its temperature is further reduced before finally being discharged into the atmosphere. However, due to the large size of the RTO furnace, the waste gas is directly introduced into the combustion chamber through the regenerative chamber. Turbulence easily forms within the combustion chamber, preventing directional flow. Furthermore, the actual combustion range within the combustion chamber is limited, meaning some waste gas may not be converted into flue gas through combustion, resulting in mixed waste gas in the discharged flue gas and low combustion efficiency.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure to solve the problem of low combustion efficiency caused by turbulence inside the existing RTO equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure includes an RTO body, a blower, an inlet manifold, an outlet manifold, a purge manifold, a burner, a rectifier, and a flow guiding device. The RTO body includes a combustion chamber and three regenerative chambers arranged sequentially at the bottom of the RTO body. The combustion chamber is located at the top of the RTO body and is connected to the combustion chamber. The blower is connected to one end of the inlet manifold. Each regenerative chamber is connected to the inlet manifold, the outlet manifold, and the purge manifold, respectively. The burner is located at the top of the combustion chamber. The rectifier is mounted on one end of each of the three regenerative chambers near the combustion chamber. The flow guiding device is located around the burner within the combustion chamber.

[0007] As described above, the three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure includes a first guiding mechanism, a second guiding mechanism, and a third guiding mechanism. The first guiding mechanism and the second guiding mechanism are respectively and correspondingly located above two spaced-apart regenerative chambers. The first guiding mechanism and the second guiding mechanism are symmetrically arranged along the central axis of the combustion chamber, and the third guiding mechanism is arranged around the burner.

[0008] As described above, the three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure includes a plurality of first guide plates. The plurality of first guide plates are arranged obliquely upward along the width direction of the RTO body, and each first guide plate is inclined relative to the height direction of the RTO body.

[0009] As described above, the three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure includes two guiding components. The two guiding components are respectively located on both sides of the combustion chamber in the width direction, and a channel is formed between the two guiding components. Each guiding component includes multiple second guiding plates, which are arranged in an arc around the burner.

[0010] As described above, in the three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure, the first guide plate and the second guide plate have the same structure. The first guide plate includes a first inclined portion, a second inclined portion, and a spiral portion. The two ends of the spiral portion are respectively connected to the first inclined portion and the second inclined portion.

[0011] The three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure as described above includes a perforated plate as the rectifying device.

[0012] In the three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure as described above, the perforated plate has a regular hexagonal shape for the holes.

[0013] Beneficial effects:

[0014] This utility model discloses a three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure, comprising an RTO body, a blower, an inlet manifold, an outlet manifold, a purge manifold, a burner, a rectifier, and a flow guiding device. The RTO body includes a combustion chamber and three regenerative chambers, each of which is connected to the inlet manifold, the outlet manifold, and the purge manifold. The three regenerative chambers respectively perform inlet, outlet, and purge operations. During the next combustion operation, the regenerative chamber that performed outlet operation in the previous operation performs inlet operation, and the regenerative chamber that performed purge operation in the previous operation performs combustion in this operation. During operation, exhaust gas is discharged, and the regenerator chamber that performed air intake in the previous incineration operation is purged during this incineration operation. This cycle repeats. Exhaust gas enters any of the regenerator chambers through the fan and the main intake pipe. After heat exchange in the regenerator chamber, the rectifier rectifies the exhaust gas, dispersing it in the combustion chamber. The dispersed exhaust gas forms a directional airflow through the guide device, and the burner triggers combustion. The three-bed regenerator RTO equipment with airflow guidance structure disclosed in this application re-guides the dispersed exhaust gas to form a directional airflow, ensuring more uniform combustion and improving the combustion efficiency of the RTO equipment.

[0019] In the description of this utility model, it should be understood that the terms "top" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation" and "connection" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figure 1-2 As shown in the figure, this application proposes a three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure, including an RTO body 1, a blower 2, an inlet manifold 3, an outlet manifold 4, a purge manifold 5, a burner 6, a rectifier 7, and a flow guiding device 8. The RTO body 1 includes a combustion chamber 11 and three regenerative chambers 12, which are arranged sequentially on the bottom of the RTO body 1. The combustion chamber 11 is located on the top of the RTO body 1, and all three regenerative chambers 12 are connected to the combustion chamber 11. The blower 2 is connected to one end of the inlet manifold 3. Each regenerative chamber 12 is connected to the inlet manifold 3, the outlet manifold 4, and the purge manifold 5, respectively. The burner 6 is located on the top of the combustion chamber 11. The rectifier 7 is mounted on one end of the three regenerative chambers 12 near the combustion chamber 11. The flow guiding device 8 is located around the burner 6 within the combustion chamber 11.

[0021] This utility model discloses a three-bed regenerative thermal oxidizer (RTO) with an airflow guiding structure, comprising an RTO body 1, a blower 2, an inlet manifold 3, an outlet manifold 4, a purge manifold 5, a burner 6, a rectifier 7, and a flow guiding device 8. The RTO body 1 includes a combustion chamber 11 and three regenerative chambers 12. Each regenerative chamber 12 is connected to the inlet manifold 3, the outlet manifold 4, and the purge manifold 5, respectively. The three regenerative chambers 12 respectively perform inlet, outlet, and purge operations. When performing the next combustion operation, the regenerative chamber 12 that performed outlet operation in the previous combustion operation performs inlet operation, and the regenerative chamber 12 that performed purge operation in the previous combustion operation performs inlet operation. 2. During this incineration operation, exhaust gas is discharged, and the regenerator chamber 12 that performed air intake in the previous incineration operation is purged during this incineration operation. This cycle repeats. The exhaust gas enters any of the regenerator chambers 12 through the fan 2 and the main intake pipe 3. After heat exchange in the regenerator chamber 12, the rectifier 7 rectifies the exhaust gas, dispersing it in the combustion chamber 11. The dispersed exhaust gas forms a directional airflow through the guide device 8, and the burner 6 triggers the combustion of the exhaust gas. The three-bed regenerator RTO equipment with airflow guiding structure disclosed in this application re-guides the dispersed exhaust gas to form a directional airflow, ensuring more uniform combustion and improving the combustion efficiency of the incineration RTO equipment.

[0022] The flow guiding device 8 includes a first flow guiding mechanism 81, a second flow guiding mechanism 82, and a third flow guiding mechanism 83. The first flow guiding mechanism 81 and the second flow guiding mechanism 82 are respectively and correspondingly arranged above the two spaced heat storage chambers 12. The first flow guiding mechanism 81 and the second flow guiding mechanism 82 are symmetrically arranged along the central axis of the combustion chamber 11. The third flow guiding mechanism 83 is arranged around the burner 6. The first flow guiding mechanism 81 and the second flow guiding mechanism 82 guide the exhaust gas on both sides of the combustion chamber 11 toward the center. Combined with the third flow guiding mechanism 83, the exhaust gas is gathered again, so that the exhaust gas is concentrated for combustion, reducing the amount of exhaust gas residue on both sides of the combustion chamber 11 and improving the combustion efficiency.

[0023] The first flow guiding mechanism 81 includes a plurality of first flow guiding plates, which are arranged obliquely upward along the width direction of the RTO body 1. Each first flow guiding plate is inclined relative to the height direction of the RTO body 1. The third flow guiding mechanism 83 includes two flow guiding components, which are respectively disposed on both sides of the combustion chamber 11 in the width direction, forming a channel between the two flow guiding components. Each flow guiding component includes a plurality of second flow guiding plates, which are arranged in an arc around the burner 6. The first and second flow guiding plates have the same structure. The first flow guiding plate includes a first inclined portion 811, a second inclined portion 812, and a spiral portion 813. The two ends of the spiral portion 813 are respectively connected to the first inclined portion 811. 1. Connected to the second inclined portion 812, in actual use, the exhaust gas near the burner 6 can directly enter and flow to the burner 6, and the flame of the burner 6 weakens outward in an elliptical shape. By tilting the first guide plate, the exhaust gas on both sides of the combustion chamber 11 is guided towards the burner 6, avoiding collisions between the exhaust gas and other parts of the combustion chamber 11 that would cause turbulence. The airflow outside the second guide plate enters the middle of the third guide mechanism 83 through the first inclined portion 811 and the second inclined portion 812 respectively. The airflow inside the second guide plate converges towards the center of the third guide mechanism 83 through the spiral portion 813, so that the exhaust gas is concentrated for combustion. The channel formed between the two guide components reduces the obstruction to the lateral flow of the airflow.

[0024] The rectifier 7 includes a perforated plate with hexagonal holes. The perforated plate disperses the airflow, thereby reducing turbulence.

[0025] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
