Description

Technical Field

[0001] The present invention relates to the field of RTO technology, and in particular to an RTO device for treating organic waste gas. Background Art

[0002] RTO is a treatment device for volatile organic compounds (VOCs). It decomposes VOCs through high-temperature oxidation, converting them into carbon dioxide and water, and uses thermal storage materials to recover heat to improve energy efficiency. RTO systems are usually designed with fans, combustion chambers, multiple thermal storage chambers, ceramic thermal storage bodies, inlet switching valves and outlet switching valves. The core lies in the ingenious switching of ceramic thermal storage bodies and switching valves.

[0003] During operation, each switching valve switches in a predetermined sequence to achieve effective heat exchange and oxidation treatment of the exhaust gas. For example, in a two-chamber RTO, first, the VOCs organic waste gas to be treated is introduced into one of the regenerators. At this time, the ceramic regenerator in the regenerator begins to release heat to the exhaust gas due to the heat stored in the previous cycle, causing the exhaust gas temperature to rise and the regenerator temperature to drop. Then, the preheated exhaust gas then enters the combustion chamber, heating the exhaust gas to above 700°C, causing the organic matter in the exhaust gas to be oxidized and decomposed into carbon dioxide and water. The high-temperature gas produced by the oxidation reaction flows through another regenerator again, transferring heat to the regenerator in the regenerator, causing the regenerator to heat up, store heat, and the gas temperature to drop. The above process is completed in one cycle, and then the flow direction of the exhaust gas and clean air is changed by the switching valve, so that each regenerator acts as a preheating chamber and an oxidation chamber in turn, forming a continuous cycle operation.

[0004] The switching valve is one of the key components of the RTO system. Frequent switching and opening and closing actions are not only cumbersome to operate and the overall operation is not smooth, but may also cause wear of the valve seals and cause leakage problems. The replacement of the switching valve is particularly expensive. In addition, if the valve cannot be switched accurately and timely, it will affect the flow of gas, resulting in reduced treatment efficiency and even safety risks. Therefore, the present invention proposes an RTO device for treating organic waste gas. Summary of the invention

DETAILED DESCRIPTION

[0032] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] Example 1: An RTO device for treating organic waste gas, such as Figures 1 to 5As shown, it includes a chassis 101, an exhaust pipe 102 is fixedly connected to the right side of the chassis 101, the exhaust pipe 102 is used to discharge the exhaust gas discharged from the combustion treatment, an intake pipe 103 is horizontally penetrated in the exhaust pipe 102, a guide pipe 104 is fixedly connected to the left side of the chassis 101, the guide pipe 104 is set in a C shape, and a rotating disk 105 is rotatably connected in the middle of the chassis 101. The upper and lower ends of the guide pipe 104 are connected to the left side of the middle of the chassis 101 near the rotating disk 105, the exhaust pipe 102 and the intake pipe 103 are connected to the right side of the middle of the chassis 101 near the rotating disk 105, four evenly distributed ceramic heat storage bodies 106 are fixedly connected to the rotating disk 105, and a plurality of circumferentially distributed drain ports 107 are opened on the outer side of the rotating disk 105. The inlet on the upper side of the guide pipe 104 is fixedly connected to Gas piece 108, the gas guide piece 108 is set to a hollow truncated cone shape, which is used to accelerate the exhaust gas into the guide pipe 104. A motor 109 is fixedly connected to the side of the chassis 101 close to the guide pipe 104, and the output shaft of the motor 109 is fixedly connected to the rotating disk 105. An intake controller 110 and a gas controller 111 are fixedly connected to the left side of the chassis 101. The intake controller 110 is located below the gas controller 111. The pipe openings of the intake controller 110 and the gas controller 111 are both inserted into the guide pipe 104. An adjusting column 112 is slidably connected to the pipe of the gas controller 111 in the up and down directions. A storage bottle 113 is fixedly connected to the top middle of the chassis 101. Gas is stored in the storage bottle 113. The storage bottle 113 is connected to the pipeline of the gas controller 111, and the adjusting column 112 is provided with a transversely penetrating channel 114.

[0034] like Figure 6 to Figure 7 As shown, it also includes a first fixing frame 201, which is fixed in the guide tube 104, the first fixing frame 201 is rotatably connected to a rotating plate 202, the rotating plate 202 is rotatably connected to a connecting rod 203, the adjusting column 112 is fixed to a sliding rod 204, and the sliding rod 204 is rotatably connected to the connecting rod 203.

[0035] First, the air intake controller 110 and the gas controller 111 have been turned on, the gas in the storage bottle 113 and the oxygen introduced from the outside enter the guide tube 104 through the gas controller 111 and the air intake controller 110 respectively, the gathering area of ​​the gas and oxygen is the oxidation reaction area, the ceramic heat storage body 106 on the front side has stored heat in the last circulation process, and the ceramic heat storage body 106 on the upper side has stored heat in the last circulation process, the exhaust gas enters the chassis 101 through the air intake pipe 103, and first passes through the ceramic heat storage body 106 on the upper side, the ceramic heat storage body 106 on the upper side begins to release heat to the exhaust gas, so that the exhaust gas temperature increases, and the upper ceramic heat storage body 106 The temperature of the ceramic heat storage body 106 on the side drops, and under the guidance of the air guide 108, the preheated exhaust gas flows along the guide pipe 104. When passing through the oxidation reaction zone, VOCs are oxidized and decomposed into carbon dioxide and water by high-temperature oxidation. The exhaust gas after combustion treatment continues to flow to the right along the guide pipe 104, and the water flows to the rotating disk 105 and is discharged through the drain port 107 at the bottom. When passing through the ceramic heat storage body 106 on the lower side, the high-temperature exhaust gas transfers its heat to the ceramic heat storage body 106 on the lower side, so that the ceramic heat storage body 106 on the lower side is stored in heat in this cycle, the temperature of the exhaust gas drops, and it is discharged along the exhaust pipe 102.

[0036] After completing the above-mentioned exhaust gas treatment, the control motor 109 drives the rotating disk 105 to rotate 90 degrees, so that the ceramic heat storage body 106 whose temperature drops on the upper side rotates to the rear side, the ceramic heat storage body 106 that has stored heat on the front side rotates to the upper side, and the ceramic heat storage body 106 that has stored heat on the lower side rotates to the front side, and then the exhaust gas entering through the intake pipe 103 repeats the above-mentioned treatment operation again, and this cycle continues.

[0037] In summary, compared with the traditional ceramic heat storage body 106 fixedly arranged in different heat storage chambers, the present invention drives the rotating disk 105 through the motor 109 to drive the four ceramic heat storage bodies 106 to rotate alternately, thereby realizing the switching of the ceramic heat storage body 106, without the need to convert the switching valve, thereby solving a series of disadvantages caused by the switching valve.

[0038] In the above process, when the exhaust gas enters the guide tube 104 from the upper side, it will pass through the rotating plate 202. Driven by the exhaust gas, the rotating plate 202 rotates to the left, thereby pushing the sliding rod 204 to move upward through the connecting rod 203, and then pushing the adjusting column 112 upward to make the channel 114 move upward, and the gas flows into the pipeline of the gas controller 111 through the channel 114. The more the exhaust gas intake, the greater the thrust pushing the rotating plate 202 to rotate to the left, and finally the greater the distance the adjusting column 112 slides upward, that is, the larger the channel 114 connecting the adjusting column 112 and the pipeline of the gas controller 111, the greater the gas intake. In this way, the gas intake can be automatically regulated according to the exhaust gas intake, thereby regulating the combustion fire.

[0040] When the exhaust gas enters through the intake pipe 103, it will push the suction fan 303 to rotate, thereby accelerating the entry of the exhaust gas. The suction fan 303 drives the first rotating shaft 302 to rotate, and the first rotating shaft 302 drives the second rotating shaft 305 to rotate through the bevel gear set 304, thereby driving the exhaust fan 306 to rotate, thereby accelerating the discharge of the exhaust gas.

[0041] Embodiment 3: Based on embodiment 2, Figure 10 to Figure 11 As shown, it also includes an insulation shell 401, which is fixed to the outside of the chassis 101 close to the rotating disk 105. The lower part of the insulation shell 401 is connected to a drain pipe 402, and the drain pipe 402 passes through the chassis 101.

[0042] The heat-insulating shell 401 can insulate the ceramic heat storage body 106 on the rotating disk 105 to prevent the ceramic heat storage body 106 from being lost, and the water generated by the oxidation reaction can be discharged through the drain pipe 402.
