Regenerative Thermal Oxidation (RTO) technology, as a highly efficient method for treating organic waste gas, has been widely applied in various industries. However, conventional incinerators with removal efficiencies of 99%–99.5% often fail to consistently achieve the desired results when treating high-concentration, low-limit waste gas due to factors such as valve switching and leakage.

[0025] like Figure 1As shown, the high-efficiency regenerative thermal oxidizer includes an incinerator 100, a mixing unit 200, a heat transfer system 300, and a catalytic plate 400. The incinerator 100 is a hollow structure with an inlet and an outlet. The incinerator 100 is located on one side of the mixing unit 200 and is connected to the mixing unit 200 by a pipeline. The mixing unit 200 is a hollow shell suitable for secondary treatment of waste gas, allowing the waste gas to be mixed. The heat transfer system 300 is fixedly installed inside the mixing unit 200, dividing the mixing unit into upper and lower layers, and the waste gas can pass through the heat transfer system 300. The catalytic plate 400 is a mesh structure with a preset thickness. The mesh structure of the catalytic plate 400 is filled with catalyst. The catalytic plate 400 is located in the upper layer inside the mixing unit 200 and at the tail end of the heat transfer system 300.

[0026] Specifically, such as Figure 1 As shown, the specific structure of the high-efficiency regenerative thermal oxidizer includes an incinerator 100, a mixing unit 200, a heat transfer system 300, and a catalytic plate 400. To allow material to enter the incinerator 100, the incinerator 100 is configured as a hollow structure with an inlet and an outlet, allowing the material to burn within the incinerator 100. The combustion of the material in the incinerator generates high-temperature waste gas and low-temperature waste gas. To treat the high-temperature and low-temperature waste gases, two mixing units 200 are provided. The mixing units 200 and the incinerator 100 are connected by pipelines, allowing the high-temperature waste gas to pass through the mixing unit. High-temperature and low-temperature exhaust gases can enter the mixing unit 200. Similarly, to accommodate both high-temperature and low-temperature exhaust gases, the mixing unit 200 is a hollow shell. To treat these gases, a heat transfer system 300 and a catalytic plate 400 are incorporated into the mixing unit 200. Both are located inside the mixing unit 200, with the heat transfer system 300 dividing it into upper and lower layers. This allows for secondary or even multiple treatments of the high-temperature and low-temperature exhaust gases. Because VOCs are present in both the high-temperature and low-temperature exhaust gases, and VOC emissions are harmful to the environment, a catalytic plate 400 is included. The catalytic plate 400 is a mesh structure with a predetermined thickness, filled with a catalyst. The high-temperature and low-temperature exhaust gases react with the catalyst as they pass through the catalytic plate 400, removing VOCs.

[0027] In one possible implementation, the heat transfer system 300 includes a first heat transfer plate 310, a second heat transfer plate 320, a third heat transfer plate 330, and a fourth heat transfer plate 340; the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 are all arranged perpendicular to the bottom of the mixing unit 200, the tops of the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 are all connected to the top of the mixing unit 200, and the bottoms of the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 are all connected to the bottom of the mixing unit 200; the fourth heat transfer plate 340 is arranged parallel to the bottom of the mixing unit 200, dividing the mixing unit 200 into upper and lower layers, and the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 penetrate through the fourth heat transfer plate 340. The first heat transfer plate 310 is disposed on the side close to the mixing unit 200, and there is a preset distance between the first heat transfer plate 310 and the side of the mixing unit 200; the third heat transfer plate 330 is disposed on the side of the first heat transfer plate 310, and there is a preset distance between the third heat transfer plate 330 and the first heat transfer plate 310; the second heat transfer plate 320 is disposed between the first heat transfer plate 310 and the third heat transfer plate 330, and there is a preset distance between the second heat transfer plate 320 and both the first heat transfer plate 310 and the third heat transfer plate 330.

[0028] Specifically, such as Figure 1 As shown, the specific structure of the heat transfer system 300 includes a first heat transfer plate 310, a second heat transfer plate 320, a third heat transfer plate 330, and a fourth heat transfer plate 340. The first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 are all arranged perpendicular to the bottom of the mixing unit 200, and the fourth heat transfer plate 340 is arranged parallel to the bottom of the mixing unit 200. This arrangement divides the interior of the mixing unit 200 into upper and lower layers. The first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 are arranged on one side of the mixing unit 200, and there is a preset distance between the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330. Arranging the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 on one side of the mixing unit 200 is to save space on the other side of the mixing unit for placing the catalyst plate 400. The first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 are connected through the fourth heat transfer plate 340, so that there are heat transfer plates on both the upper and lower layers. Through the double-layer heat transfer plate system, the heat of the secondary treated waste gas is transferred to the primary treated waste gas on the upper layer, which increases the initial temperature required for the catalytic reaction and at the same time reduces the temperature of the purified flue gas after secondary treatment.

[0029] In one possible implementation, two through holes are provided on the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330, and the two through holes on the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 are symmetrically arranged with respect to the fourth heat transfer plate 340; the fourth heat transfer plate 340 is also provided with two through holes, namely a first through hole 341 and a second through hole 342, and the first through hole 341 is provided at one end of the fourth heat transfer plate 340 and is located between the first heat transfer plate 310 and one side of the mixing unit 200, and the second through hole 342 is provided at the other end of the fourth heat transfer plate 340.

[0030] Specifically, such as Figure 2 As shown, in order to allow high-temperature and low-temperature exhaust gases to pass through the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330, through holes are provided on each of the three heat transfer plates. Furthermore, each of the three heat transfer plates has two pipe perforations, ensuring that both high-temperature and low-temperature exhaust gases can pass through the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330, regardless of whether they are in the upper or lower layer. Similarly, in order to enable high-temperature exhaust gas and low-temperature exhaust gas to circulate between the upper and lower layers, two through holes are also provided on the fourth heat transfer plate 340, namely the first through hole 341 and the second through hole 342. The first through hole 341 is provided at one end of the fourth heat transfer plate 340 and is located between the first heat transfer plate 310 and one side of the mixing unit 200. The second through hole 342 is provided at the other end of the fourth heat transfer plate 340.

[0031] Through holes are made in the first heat transfer plate 310, the second heat transfer plate 320, the third heat transfer plate 330 and the fourth heat transfer plate 340 to form channels for the passage of exhaust gas, so that the airflow forms a deflection.

[0032] In one possible implementation, the catalytic plate 400 is disposed on the upper layer of the mixing unit 200, with its top connected to the top of the mixing unit 200 and its bottom connected to the fourth heat transfer plate 340; the second through hole 342 is located between the catalytic plate 400 and the other side of the mixing unit 200. The catalytic plate 400 and the fourth heat transfer plate 340 have an included angle α, and the included angle α is in the range of 20°≤α≤30°.

[0033] Specifically, to create a temperature difference between the upper and lower layers of exhaust gas, a catalytic plate 400 is installed at the other end of the third heat transfer plate 330 and the mixing unit 200. To allow both high-temperature and low-temperature exhaust gas to pass through the catalytic plate 400 before entering the lower layer, the second through hole 342 is located between the catalytic plate 400 and the mixing unit 200 on the other side. To increase the contact between the high-temperature and low-temperature exhaust gas and the catalytic plate 400, the catalytic plate 400 and the fourth heat transfer plate 340 are at an angle α, with the angle α ranging from 20° to 30°. The exhaust gas, at a higher temperature after passing through the catalytic plate 400, enters the lower layer and then passes through the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 installed in the lower layer, transferring its temperature to the upper layer. This raises the temperature of the exhaust gas in the upper layer, making it suitable for reaction with the catalytic plate 400 and resulting in heat recovery.

[0034] In one possible implementation, a triple-eccentric butterfly valve 500 is also included, which is disposed on the first through hole 341. The triple-eccentric butterfly valve 500 allows for direct opening when secondary processing is not required, enabling direct drainage from top to bottom. The triple-eccentric butterfly valve 500 is employed because its sealing technology and unique structural design ensure absolutely no leakage during valve switching.

[0035] In one possible implementation, a high-temperature exhaust gas outlet is provided at the top of the incinerator, a low-temperature exhaust gas outlet is provided at the bottom of the incinerator, and a high-temperature exhaust gas inlet and a low-temperature exhaust gas inlet are provided on the mixing unit, with the high-temperature exhaust gas outlet and the high-temperature exhaust gas inlet connected by a pipeline, and the low-temperature exhaust gas inlet and the low-temperature exhaust gas outlet connected by a pipeline.

[0036] In one possible implementation, a mode switching system and a control system are also included, both of which are located within the hybrid unit and are electrically connected. Both the mode switching system and the control system are suitable for connection to an external computer.

[0037] By setting up a mode switching system and control system, the whole system becomes more intelligent. It can automatically switch between catalytic treatment mode and conventional mixing box mode according to the needs of waste gas treatment without manual intervention. It can monitor parameters such as waste gas composition, flow rate and temperature in real time, and automatically adjust the working parameters based on these parameters. It can also monitor and adjust the heat recovery ratio in real time to ensure the best energy saving effect under different operating conditions.

[0038] A flow guide 600 is provided on the heat transfer plate system. The flow guide 600 consists of multiple grooves with a preset length. The flow guide 600 is distributed on the first heat transfer plate 310, the second heat transfer plate 320, the third heat transfer plate 330 and the fourth heat transfer plate 340. This is to help the exhaust gas to flow better in this direction and avoid dead corners or stagnation.

[0039] It should be noted that the heat transfer plates at the bottom of the vertical mixing unit 200 can be more than three, and the heat transfer plates at the bottom of the parallel mixing unit 200 can be more than one, or multiple as needed. In other words, the spacing and number of heat transfer plates can be set in multiple ways to adapt to different heat transfer efficiency and removal rate requirements.

[0040] A highly efficient regenerative thermal ignition (RTI) incineration method, using the aforementioned highly efficient RTI incineration device, includes the following steps: First, material enters the incinerator through the feed inlet, where it is incinerated to generate high-temperature waste gas and low-temperature waste gas. The high-temperature waste gas exits through a pipe into a mixing unit, and the low-temperature waste gas exits through a pipe into the mixing unit. The high-temperature and low-temperature waste gases mix in the mixing unit to form a mixed waste gas. At this point, the mixed waste gas is located in the upper layer of the mixing unit. After passing through perforations in the first, second, and third heat transfer plates, the mixed waste gas passes through a catalytic plate and is heated by the catalyst on the catalytic plate. The heated mixed waste gas then enters the lower layer through the second through-hole of the fourth heat transfer plate, meeting emission standards. Finally, it is discharged through the exhaust port in the lower layer.

[0041] This application achieves a high overall removal rate through the synergistic effect of the heat transfer plate system and the catalytic plate. It utilizes the heat generated by the catalytic reaction to heat the upper waste gas, improving energy utilization efficiency and reducing operating costs. The triple-eccentric butterfly valve design allows the equipment to be flexibly converted to a conventional mixing chamber when no additional improvement in removal efficiency is needed. Furthermore, the integrated mode switching and control systems enhance the overall intelligence, automatically switching between catalytic treatment mode and conventional mixing chamber mode according to waste gas treatment requirements without manual intervention. It can monitor waste gas composition, flow rate, and temperature in real time and automatically adjust operating parameters accordingly. It can also monitor and adjust the heat recovery ratio in real time, ensuring optimal energy saving under different operating conditions. Through these features, this application achieves high overall system removal efficiency while saving energy, solving the technical problem of existing incineration devices requiring increased fuel consumption to maintain high treatment efficiency, leading to increased energy consumption and overall high energy consumption.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
