Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, and specifically relates to an adaptive RTO reactor. Background Technology

[0002] Regenerative Thermal Oxidizer (RTO) is a highly efficient combustion technology widely used in industrial waste gas treatment. Its core principle is to recover the heat generated during combustion through a regenerative ceramic body, which is then used to preheat the incoming waste gas, thereby reducing auxiliary fuel consumption and improving thermal efficiency. However, traditional RTO systems still face the following technical bottlenecks in practical applications;

[0003] Traditional RTOs have a fixed combustion chamber space. When the exhaust gas flow rate is low, the combustion space is too large, resulting in heat dispersion and incomplete combustion. At high flow rates, the combustion space may be insufficient, leading to a short exhaust gas residence time and incomplete oxidation. Furthermore, existing RTO systems typically rely on external sensors (such as flow meters and oxygen analyzers) and electric / pneumatic actuators to regulate the supply of fuel and combustion air. This control method has response delays and is prone to adjustment deviations under complex operating conditions, affecting combustion efficiency.

[0004] To address the aforementioned issues, this application proposes an adaptive RTO reactor. Summary of the Invention

[0005] In response to the problems in related technologies, this invention proposes an adaptive RTO reactor to overcome the aforementioned technical problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adaptive RTO reaction vessel includes a tank box, an isolation plate is fixedly installed on the inner wall of the tank box, a bottom box is fixedly installed on the top of the isolation plate, an annular rotating box is rotatably connected to the top of the bottom box, the annular rotating box and the bottom box are interconnected, multiple mounting boxes are installed on the top of the annular rotating box, an isolation box is fixedly installed on the top of the bottom box, a movable box is slidably connected to the top of the isolation box, and multiple exhaust pipes are installed on the side of the movable box.

[0008] The pneumatic sealing mechanism includes multiple rotating cylinders, which are rotatably mounted on the top of their respective mounting boxes. An angle nozzle is fixedly mounted on the top of each rotating cylinder.

[0009] An adaptive combustion-supporting mechanism includes multiple L-shaped exhaust pipes, each of which is fixedly installed on one side of a mounting box, and the L-shaped exhaust pipes are interconnected with the mounting box.

[0010] The combustion mechanism includes multiple control boxes. A fuel box is rotatably connected to the top of the bottom box. Multiple control boxes are fixedly installed on the top of the fuel box and are interconnected with each other. A gas nozzle is fixedly installed on the top of the control box.

[0011] Preferably, the pneumatic sealing mechanism further includes a rotating tube, which is rotatably mounted on the outside of the movable box. Multiple pull rods are hinged to the outside of the rotating tube. A positioning shaft is fixedly mounted on one side of the rotating cylinder, and a push rod is fixedly mounted on one end of the positioning shaft. The push rod is rotatably connected to the corresponding pull rod.

[0012] The movable box that moves up and down is connected to the rotating tube by its lateral rotation, which in turn drives the rotating tube to move up and down. The rotating tube is connected to the pull rod by a hinge, which drives the pull rod upward. The pull rod pulls the push rod to change the angle, which in turn drives the rotating cylinder to change the angle through the positioning shaft, thereby adjusting the exhaust angle of the L-shaped exhaust pipe.

[0013] Preferably, the adaptive combustion-supporting mechanism further includes an adjustment plate, which is slidably connected to the L-shaped exhaust pipe. A connecting shaft is fixedly installed on the top of the adjustment plate, and a slider is rotatably connected to one end of the connecting shaft. The slider is slidably connected to the corresponding push rod.

[0014] The angle-adjustable push rod is slidably connected to the slider, thereby adjusting the height of the adjusting plate via the connecting shaft, which in turn adjusts the exhaust volume of the L-shaped exhaust pipe, thus regulating the oxygen content of the fuel.

[0015] Preferably, the combustion mechanism further includes a baffle, which is slidably connected to the bottom of the control box, and a hinge rod is rotatably connected to the top of the baffle, the hinge rod being rotatably connected to the rotating tube.

[0016] The movable rotating tube moves by pulling the baffle through the hinge rod. The baffle is slidably connected to the bottom of the control box, so the movable baffle can adjust the amount of communication between the control box and the fuel box, thereby adjusting the amount of fuel discharged and thus adjusting the combustion intensity of the fuel.

[0017] Preferably, an annular conversion box is fixedly connected to the top of the bottom box, the annular conversion box is rotatably connected to the fuel box, and the annular conversion box and the fuel box are in communication with each other. A fuel pipe is installed at the bottom of the annular conversion box, and one end of the fuel pipe extends to the outside of the tank.

[0018] The fuel box is interconnected with the annular converter box, which enables the annular converter box to continuously supply fuel to the rotating fuel box.

[0019] Preferably, the tank is equipped with a combustion-supporting pipe, one end of which is connected to the bottom box.

[0020] Combustion-supporting air is introduced into the bottom box through the combustion-supporting pipe, thereby assisting the combustion of the gas.

[0021] Preferably, a fixing rod is fixedly installed on the inner wall of the isolation box, and a tension spring is fixedly installed on the top of the fixing rod, with the top of the tension spring fixedly connected to the top inner wall of the movable box.

[0022] The use of a fixing rod and a tension spring facilitates the repositioning of the movable box, allowing it to maintain downward movement even under low stress.

[0023] Preferably, a spiral air inlet pipe and a spiral air return pipe are installed on the inner wall of the tank, the spiral air inlet pipe and the spiral air return pipe are staggered, and the top end of the spiral air inlet pipe passes through the isolation plate and is connected to the isolation box, and the top end of the spiral air return pipe passes through the tank and is placed above the isolation plate.

[0024] The exhaust gas is introduced into the tank through the spiral intake pipe and then directed above the baffle plate for combustion. As it passes below the baffle plate, it is preheated by the water source there. The spiral return pipe discharges the combusted gas and recovers the heat through the water source below the baffle plate.

[0025] Preferably, a reinforcing frame is fixedly installed on the outside of the tank, and an inlet and a outlet are installed on the tank, both of which are equipped with valves.

[0026] The reinforcement frame facilitates the fixed support of the tank, thereby increasing its strength. At the same time, the water inlet and outlet allow for the replacement of the water source inside the tank.

[0027] In summary, the technical effects and advantages of this invention are as follows:

[0028] 1. Dynamic sealed combustion space design

[0029] By linking the annular rotating box with the curved nozzle, the reaction force drives the annular rotating box to rotate, forming a dynamic closed combustion space at an angled upward.

[0030] When the exhaust gas flow rate changes, the lifting and lowering of the movable box is adjusted by the rotation tube and the linkage to adjust the angle of the rotating cylinder, adaptively adjusting the size of the combustion space to ensure complete combustion under different flow rates.

[0031] 2. Fuel and combustion adaptive control system

[0032] Dynamic fuel regulation: The displacement of the moving box is linked to the baffle via the hinge rod, which adjusts the connection between the fuel box and the control box in real time to achieve adaptive matching of combustion intensity.

[0033] Precise oxygen supply: Changes in the push rod angle drive the adjustment plate via a slider and connecting shaft, dynamically controlling the exhaust volume of the L-shaped exhaust pipe and optimizing the mixing ratio of gas and oxygen.

[0034] 3. Rotary multi-nozzle synergistic combustion enhancement

[0035] The rotation of the annular rotating box drives multiple mounting boxes to rotate synchronously, causing the bend nozzle to form an annular airflow barrier, enhancing the sealing performance. At the same time, the combustion-supporting gas flow of the L-shaped exhaust pipe is evenly distributed with the rotation, improving combustion efficiency.

[0036] 4. Dual-loop recovery of waste gas and heat

[0037] The spiral intake pipe and spiral return pipe are staggered, allowing exhaust gas preheating and post-combustion heat recovery to occur simultaneously.

[0038] The exhaust gas is preheated by a water source below the isolation plate;

[0039] After combustion, the high-temperature gas transfers heat back to the water source through a spiral return pipe, forming an energy cycle. Attached Figure Description

[0056] Reference Figure 5 and Figure 9The pneumatic sealing mechanism 7 also includes a rotating tube 10, which is rotatably mounted on the outside of the movable box 4. Multiple pull rods 75 are hinged to the outside of the rotating tube 10. A positioning shaft 73 is fixedly mounted on one side of the rotating cylinder 71. A push rod 74 is fixedly mounted on one end of the positioning shaft 73. The push rod 74 is rotatably connected to the corresponding pull rod 75. The movable box 4, which moves up and down, is connected to the rotating tube 10 by lateral rotation, thereby driving the rotating tube 10 to move up and down. The rotating tube 10 is hinged to the pull rod 75, which drives the pull rod 75 upward. The pull rod 75 pulls the push rod 74 to change the angle, which in turn drives the rotating cylinder 71 to change the angle through the positioning shaft 73, thereby adjusting the exhaust angle of the L-shaped exhaust pipe 81.

[0057] Reference Figure 9 The adaptive combustion-supporting mechanism 8 also includes an adjustment plate 84, which is slidably connected to the L-shaped exhaust pipe 81. A connecting shaft 83 is fixedly installed on the top of the adjustment plate 84, and a slider 82 is rotatably connected to one end of the connecting shaft 83.

[0058] Reference Figure 8 The combustion mechanism 9 also includes a baffle 94, which is slidably connected to the bottom of the control box 91. A hinge rod 93 is rotatably connected to the top of the baffle 94, and the hinge rod 93 is rotatably connected to the rotating tube 10. An annular conversion box 96 is fixedly connected to the top of the bottom box 16, and the annular conversion box 96 is rotatably connected to the fuel box 95 and the annular conversion box 96 and the fuel box 95 are interconnected. A fuel pipe 97 is installed at the bottom of the annular conversion box 96, and one end of the fuel pipe 97 extends to the outside of the tank 1. The moving rotating tube 10 moves the baffle 94 by pulling it through the hinge rod 93. The sliding connection between the baffle 94 and the bottom of the control box 91 allows the movable baffle 94 to adjust the communication between the control box 91 and the fuel box 95, thereby adjusting the fuel output and thus the combustion intensity of the fuel. The fuel box 95 is connected to the annular conversion box 96, which allows the annular conversion box 96 to continuously supply fuel to the rotating fuel box 95. A combustion-supporting pipe 15 is installed on the tank 1, with one end of the combustion-supporting pipe 15 connected to the bottom box 16. Combustion-supporting air is introduced into the bottom box 16 through the combustion-supporting pipe 15 to assist the combustion of the gas.

[0059] Reference Figure 7A fixing rod 13 is fixedly installed on the inner wall of the isolation box 3. A tension spring 14 is fixedly installed on the top of the fixing rod 13. The top of the tension spring 14 is fixedly connected to the top inner wall of the movable box 4. The fixing rod 13 and the tension spring 14 facilitate the reset of the movable box 4, so that the movable box 4 can continue to move downward when the force is small.

[0060] Reference Figure 3 The inner wall of the tank 1 is equipped with a spiral air inlet pipe 18 and a spiral air return pipe 17. The spiral air inlet pipe 18 and the spiral air return pipe 17 are staggered. The top end of the spiral air inlet pipe 18 passes through the isolation plate 2 and is connected to the isolation box 3. The top end of the spiral air return pipe 17 passes through the tank 1 and is placed above the isolation plate 2. The exhaust gas is introduced into the tank 1 through the spiral air inlet pipe 18 and then introduced above the isolation plate 2 for convenient combustion treatment. At the same time, when passing under the isolation plate 2, it is preheated by the water source under the isolation plate 2. The spiral air return pipe 17 can discharge the gas after combustion and recover heat through the water source under the isolation plate 2.

[0061] Reference Figure 1 A reinforcing frame 19 is fixedly installed on the outside of the tank box 1, and a water inlet and a water outlet are installed on the tank box 1. Both the water inlet and the water outlet are equipped with valves. The reinforcing frame 19 can be used to fix and support the tank box 1, thereby increasing the strength of the tank box 1. At the same time, the water source inside the tank box 1 can be replaced by the water inlet and the water outlet.

[0062] Working principle: During operation, the exhaust gas is introduced into the tank 1 through the spiral inlet pipe 18 and then introduced above the isolation plate 2. When passing below the isolation plate 2, it is preheated by the water source below the isolation plate 2. The gas in the spiral inlet pipe 18 is introduced into the isolation box 3. Through the gas flow rate, it impacts and pushes the movable box 4 upward and is discharged through the exhaust pipe 5. At the same time, the outlet of the exhaust pipe 5 is set downward, which allows the gas to act directly on the gas nozzle 92, thereby directly performing combustion treatment.

[0063] During combustion, combustion-supporting air is introduced into the bottom box 16 through the combustion-supporting pipe 15 to assist the combustion of the gas. The air is then introduced into the annular rotating box 11 through the bottom box 16. The air in the annular rotating box 11 is then introduced into multiple mounting boxes 12 and sprayed out through the rotating cylinder 71 and the curved nozzles 72. At the same time, the bending design of the curved nozzles 72 causes the sprayed air to push the mounting boxes 12 in the opposite direction, thereby driving the annular rotating box 11 to rotate. Under the action of the multiple curved nozzles 72, a closed space is formed diagonally above the annular rotating box 11, so that the exhaust gas can be combusted in a fixed sealed space. When the amount of exhaust gas introduced is different, the movable box 4 is pushed up and down by the amount of air flow. The movable box 4 is connected to the rotating tube 10 by lateral rotation, which can drive the rotating tube 10 to move up and down. The rotating tube 10 is connected to the pull rod 75 by hinge, which drives the pull rod 75 to move upward. The pull rod 75 pulls the push rod 74 to change the angle, which in turn drives the rotating cylinder 71 to change the angle through the positioning shaft 73, thereby adjusting the exhaust angle of the L-shaped exhaust pipe 81. This allows the size of the enclosed space to be adjusted according to different wind forces, and the size of the combustion space to be adjusted according to the air volume, so as to facilitate the complete combustion of exhaust gas.

[0064] Fuel pipe 97 introduces gas into annular conversion box 96. The gas in annular conversion box 96 is introduced into fuel box 95 through mutual communication with fuel box 95. The gas in fuel box 95 is introduced into multiple control boxes 91 and sprayed out through gas nozzle 92. When movable box 4 moves up and down, movable box 4 drives rotating pipe 10 to move. The moving rotating pipe 10 pulls baffle 94 through hinge rod 93. Through the sliding connection between baffle 94 and the bottom of control box 91, the moving baffle 94 can adjust the amount of communication between control box 91 and fuel box 95, thereby adjusting the amount of fuel output, thereby adjusting the combustion intensity of fuel, and assisting combustion of gas through L-shaped exhaust pipe 81.

[0065] Meanwhile, the gas inside the installation box 12 is discharged through the L-shaped exhaust pipe 81 and assists the combustion of the gas sprayed from the gas nozzle 92. When the angle of the push rod 74 changes, the push rod 74 with the changing angle is slidably connected to the slider 82, so that the height of the adjustment plate 84 can be adjusted through the connecting shaft 83, thereby adjusting the exhaust volume of the L-shaped exhaust pipe 81, and thus adjusting the oxygen content during gas combustion.

[0066] The exhaust gas after combustion is discharged through the spiral return pipe 17 and the heat is recovered through the water source below the isolation plate 2. The recovered heat heats the water source, thereby preheating the gas entering the spiral intake pipe 18.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
