[0002] RTO refers to a regenerator thermal oxidizer, which is mainly used for treating organic waste gas. By first heating the waste gas and then burning the heated waste gas, the organic components in the waste gas are completely decomposed into carbon dioxide and water, so that the treated waste gas meets the emission standards.

[0024] The above scheme is adopted: the exhaust gas and the first delivery pipe 2 are delivered to the interior of the delivery box 3 through the air inlet pipe 1.

At this time, the burner 606 is started to heat the flue gas, so that the flue gas is oxidized and decomposed. The purified gas after decomposition is discharged through the first heat storage chamber 602. At this time, the heat storage ceramic plate 705 at the first heat storage chamber 602 is heated, so that the exhaust gas can contact the heated heat storage ceramic plate 705 when discharged into the combustion furnace main body 601, and then the exhaust gas is preheated by the heated heat storage ceramic plate 705, thereby improving the effect of subsequent combustion.

[0025] like Figures 1 to 7 As shown, the heat storage mechanism 7 includes a connecting plate 701, a cylinder 702 and a support bar 703. The connecting plate 701 is fixed to the inner wall of the combustion furnace body 601. The cylinder 702 is fixed to the top inner end of the connecting plate 701.

The connecting rod 704 is provided with two groups of support bars symmetrically distributed about the central axis of the support bar 703.

[0026] like Figures 1 to 7 As shown, one end of the connecting rod 704 is hinged to a heat storage ceramic plate 705, and a heat storage groove 706 is fixed on the surface of the heat storage ceramic plate 705. The connecting plates 701 are symmetrically distributed about the central axis of the first heat storage chamber 602. The connecting plates 701 are provided with three groups fixed inside the first heat storage chamber 602, the second heat storage chamber 603 and the third heat storage chamber 604. Several groups of support bars 703 are provided, and the support bars 703 are distributed in an array. The heat storage grooves 706 are in the shape of an equilateral hexagon and are distributed in an array.

[0027] The above scheme is adopted: by starting the cylinder 702 to change the height of the support bars 703 on both sides, the device can change the tilt angle of the heat storage ceramic plate 705 and the heat storage tank 706 through the cylinder 702, and then when the device introduces the exhaust gas into the interior of the combustion furnace main body 601, it contacts the heat storage ceramic plate 705 in the tilted state, and the heat storage ceramic plate 705 can guide the exhaust gas when entering, so that it quickly enters the interior of the combustion furnace main body 601 for combustion. When the exhaust gas is discharged after combustion is completed, it contacts the tilted heat storage ceramic plate 705 and the heat storage tank 706, and the exhaust gas is discharged through the tilted heat storage ceramic plate 705. 05 and the heat storage tank 706 extend the time for the flue gas to be discharged after entering the second control valve 5, thereby increasing the heat exchange time between the flue gas and the heat storage ceramic plate 705 and the heat storage tank 706, thereby improving the heat recovery effect and reducing the heat loss rate.

[0028] like Figures 1 to 13 As shown, the heat recovery mechanism 8 includes a first exhaust pipe 801, an exhaust groove 802 and a superconducting magnetic ring 803. The first exhaust pipe 801 is connected to the output end of the conveying box 3. The exhaust groove 802 is opened inside the first exhaust pipe 801. The outside of the first exhaust pipe 801 is provided with a superconducting magnetic ring 803. The outside of the first exhaust pipe 801 is provided with a heat exchange ring 804. One end of the heat exchange ring 804 is connected to the second conveying pipe 805. One end of the second conveying pipe 805 is connected to a conveying water pump 806. One end of the conveying water pump 806 is connected to a heat exchange box 807. The first exhaust pipe 801 is provided with three groups, and the superconducting magnetic ring 803 is provided with several groups. The superconducting magnetic rings 803 are distributed at equal intervals. When the superconducting magnetic ring 803 is energized, a dynamic annular magnetic field is generated inside. The magnetic lines of force of the superconducting magnetic ring 803 are spirally distributed. The heat exchange box 807 is sleeved on the outside of the first conveying pipe 2, and the interior of the heat exchange ring 804 is filled with heat exchange fluid.

[0029] The above solution is adopted: the flue gas after combustion is discharged through the first exhaust pipe 801 via the second control valve 5 and the conveying box 3. After the purified flue gas undergoes heat conversion with the heat storage ceramic plate 705, it still retains some heat. In order to minimize the heat loss rate of the device, the superconducting magnetic ring 803 is started to pass a high-frequency pulse current to generate a dynamic annular magnetic field inside the superconducting magnetic ring 803. The magnetic lines of force are spirally distributed, forcing the charged particles in the high-temperature flue gas to form vortex chains along the Lorentz force trajectory, thereby extending the residence time of the flue gas inside the first exhaust pipe 801. At this time, the heat exchange ring 804 is sleeved on the outside of the first exhaust pipe 801. When the flue gas is discharged, the decelerated flue gas is in contact with the heat exchange ring 804 for a longer period of time, thereby improving the heat conversion efficiency. The heat exchange fluid inside the heat exchange ring 804 is heated and conveyed by the conveying water pump 806. When it contacts the first conveying pipe 2, it transfers heat to the flue gas about to be injected into the combustion furnace body 601, thereby further reducing the heat loss rate of the device.

[0030] like Figures 1 to 13 As shown, the filtering mechanism 9 includes a filter box 901, a support rod 902 and a transmission fan blade 903. The input end of the filter box 901 is connected to the first exhaust pipe 801. The interior of the filter box 901 is rotatably connected to the support rod 902. The transmission fan blade 903 is fixed to the outside of the support rod 902. The scraper 904 is fixed to the outside of the support rod 902. The filter plate 905 is fixed to the inside of the filter box 901. The filter box 901 is provided with three groups, and the transmission fan blade 903 is provided with several groups. The transmission fan blades 903 are distributed at equal intervals about the central axis of the support rod 902. The scraper 904 is provided with several groups. The scraper 904 is distributed in an array. The surface of the filter plate 905 is provided with several groups of filter holes.

[0031] The above scheme is adopted: the exhaust flue gas can be filtered through the filter plate 905, and the particulate matter that has not been completely burned is blocked on the surface. When the purified flue gas is transported to the inside of the filter box 901 through the first exhaust pipe 801, it contacts the transmission fan blades 903, driving the transmission fan blades 903 to rotate, and because the flue gas moves in a spiral shape, the effect of driving the transmission fan blades 903 to rotate is improved. The transmission fan blades 903 drive the scraper 904 to rotate, and clean the particulate matter attached to the surface of the filter plate 905, thereby ensuring the effect of filtering the flue gas.

[0032] The working principle and use process of the present invention are as follows: the exhaust gas is transported to the interior of the transport box 3 through the air inlet pipe 1 and the first transport pipe 2. In the first stage, the exhaust gas is transported to the interior of the combustion furnace body 601 by opening the first control valve 4 at the bottom of the first heat storage chamber 602. At this time, the burner 606 is started to heat the flue gas, so that the flue gas is oxidized and decomposed. The purified gas after decomposition is discharged through the third heat storage chamber 604. At this time, the heat storage ceramic plate 705 at the third heat storage chamber 604 is heated. In the second stage, the first control valve 4 at the bottom of the third heat storage chamber 604 is opened. 4. The exhaust gas is transported to the interior of the combustion furnace body 601. At this time, the burner 606 is started to heat the flue gas, causing the flue gas to oxidize and decompose. The decomposed purified gas is discharged through the second regenerator 603. At this time, the heat storage ceramic plate 705 in the second regenerator 603 is heated. In the third stage, the exhaust gas is transported to the interior of the combustion furnace body 601 by opening the first control valve 4 at the bottom of the second regenerator 603. At this time, the burner 606 is started to heat the flue gas, causing the flue gas to oxidize and decompose. The decomposed purified gas is discharged through the first regenerator 602. At this time, the heat storage ceramic plate 705 at the first heat storage chamber 602 is heated, so that the exhaust gas can contact the heated heat storage ceramic plate 705 when it is discharged into the combustion furnace main body 601, and then the exhaust gas is preheated by the heated heat storage ceramic plate 705 to improve the effect of subsequent combustion, and the height of the support bars 703 on both sides is changed by starting the cylinder 702, so that the device can change the inclination angle of the heat storage ceramic plate 705 and the heat storage tank 706 through the cylinder 702, and then when the device introduces the exhaust gas into the interior of the combustion furnace main body 601, it contacts the heat storage ceramic plate 705 in the inclined state, and the heat storage ceramic plate 705 can guide the exhaust gas when entering, so that it can quickly enter the interior of the combustion furnace main body 601 for combustion, and when the exhaust gas is discharged after combustion is completed, it contacts the inclined storage ceramic plate 705. The thermal ceramic plates 705 are in contact with the heat storage tank 706. The inclined thermal storage ceramic plates 705 and the heat storage tank 706 prolong the time for the flue gas to be discharged after entering the second control valve 5, thereby increasing the heat exchange time between the flue gas and the thermal storage ceramic plates 705 and the heat storage tank 706, thereby improving the heat recovery effect and reducing the heat loss rate. At this time, the idle group of thermal storage ceramic plates 705 and the heat storage tank 706 are set to a parallel state to ensure that the purified flue gas can be discharged more smoothly from the second control valve 5 of the current stage. In the switching stage, the inclination angle of each group of thermal storage ceramic plates 705 is adjusted accordingly, so that the exhaust gas can always be guaranteed to enter quickly when entering the device, and the time required for discharge is extended to improve the heat conversion rate. The combusted flue gas is discharged through the first exhaust pipe 801 through the second control valve 5 and the conveying box 3; After the purified flue gas undergoes heat conversion with the heat storage ceramic plate 705, it still retains some heat. In order to minimize the heat loss rate of the device, the superconducting magnetic ring 803 is started to generate a dynamic annular magnetic field inside the superconducting magnetic ring 803 through a high-frequency pulse current. The magnetic lines of force are spirally distributed, forcing the charged particles in the high-temperature flue gas to form a vortex chain along the Lorentz force trajectory, thereby extending the residence time of the flue gas inside the first exhaust pipe 801. At this time, the heat exchange ring 804 is sleeved on the outside of the first exhaust pipe 801. When the flue gas is discharged after being decelerated, the contact time with the heat exchange ring 804 is extended, thereby improving the heat conversion efficiency, and heating the heat exchange fluid inside the heat exchange ring 804, and then delivering it to the heat exchanger through the water pump 804. 06 is transported so that when it contacts the first transport pipe 2, the heat is transferred to the flue gas that is about to be injected into the combustion furnace main body 601, so that the device can further reduce the heat loss rate, and the exhaust flue gas can be filtered through the filter plate 905, and the particulate matter that has not been completely burned is blocked on the surface. When the purified flue gas is transported to the inside of the filter box 901 through the first exhaust pipe 801, it contacts the transmission fan blade 903, driving the transmission fan blade 903 to rotate, and because the flue gas moves in a spiral shape, the effect of driving the transmission fan blade 903 to rotate is improved, and the transmission fan blade 903 drives the scraper 904 to rotate, and cleans the particulate matter attached to the surface of the filter plate 905, thereby ensuring the effect of filtering the flue gas.
