Description

Technical Field

[0001] The present utility model relates to the technical field of organic waste gas, and in particular to an incineration method for an efficient regenerative thermal oxidizer. Background Art

[0002] With the rapid development of industrial production, the emissions of organic waste gas are increasing day by day, posing a serious threat to the environment and human health. As an efficient technology for treating organic waste gas, the regenerative thermal oxidation technology (RTO) has been widely applied in many industries. However, when incinerators with a conventional removal efficiency of 99% - 99.5% are used to treat waste gas with high concentration and low limit values, due to factors such as valve switching / leakage, it is often impossible to stably achieve the required effect. Especially in projects with higher requirements for removal efficiency, the conventional RTO technology seems inadequate.

[0024] As Figure 1 shown, the high-efficiency regenerative incineration device includes an incinerator 100, a mixing unit 200, a heat transfer system 300, and a catalyst plate 400; the incinerator 100 is a hollow structure provided with a feed port and a discharge port, the incinerator 100 is disposed on one side of the mixing unit 200 and is connected to the mixing unit 200 through a pipeline; the mixing unit 200 is a hollow shell suitable for secondary treatment of waste gas to mix the waste gas; the heat transfer system 300 is fixedly disposed in the mixing unit 200, the heat transfer system 300 divides the mixing unit into upper and lower layers, and the waste gas can pass through the heat transfer system 300; the catalyst plate 400 is a mesh structure with a preset thickness, the mesh structure of the catalyst plate 400 is filled with a catalyst, the catalyst plate 400 is disposed in the upper layer inside the mixing unit 200 and is located at the end of the heat transfer system 300.

[0025] Specifically, as Figure 1As shown in the figure, the specific structure of the high-efficiency regenerative incineration device includes an incinerator 100, a mixing unit 200, a heat transfer system 300, and a catalytic plate 400. In order to enable materials to enter the incinerator 100, the incinerator 100 is set as a hollow structure with a feed port and a discharge port, so that the materials are burned in the incinerator 100. When the materials are burned in the incinerator, high-temperature waste gas and low-temperature waste gas will be generated. In order to treat the high-temperature waste gas and the low-temperature waste gas, two mixing units 200 are set. The mixing unit 200 is connected to the incinerator 100 through a pipeline, so that the high-temperature waste gas and the low-temperature waste gas can enter the mixing unit 200. Similarly, in order to enable the mixing unit 200 to accommodate the high-temperature waste gas and the low-temperature waste gas, the mixing unit 200 is a hollow shell. Since the mixing unit 200 is used to treat the high-temperature waste gas and the low-temperature waste gas, a heat transfer system 300 and a catalytic plate 400 are set. The heat transfer system 300 and the catalytic plate 400 are both arranged inside the mixing unit 200. The heat transfer system 300 divides the mixing unit 200 into an upper and a lower layer structure, so that the high-temperature waste gas and the low-temperature waste gas can be secondarily treated and heat energy can be recovered. Because there are VOCs in the high-temperature waste gas and the low-temperature waste gas, but the emission of VOCs is harmful to the environment, a catalytic plate 400 is set. The catalytic plate 400 is a mesh structure with a preset thickness, and the mesh structure of the catalytic plate 400 is filled with a catalyst, so that the high-temperature waste gas and the low-temperature waste gas pass through the catalytic plate 400 to react with the catalyst to remove VOCs.

[0026] In a possible implementation manner, 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, divides the mixing unit 200 into an upper and a lower layer, 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 arranged 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 arranged on one 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 arranged between the first heat transfer plate 310 and the third heat transfer plate 330, and there are preset distances between the second heat transfer plate 320 and the first heat transfer plate 310 and the third heat transfer plate 330 respectively.

[0027] Specifically, as Figure 1As shown in the figure, 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. Through such an arrangement, the interior of the mixing unit 200 is divided into upper and lower layers. One side of the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 is 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 the other side of the mixing unit for placing the catalytic plate 400. 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, so that there are heat transfer plates in both the upper and lower layers. Through the double-layer heat transfer plate system, the heat of the waste gas after secondary treatment is transferred to the waste gas treated for the first time in the upper layer, increasing the initial temperature required for the catalytic reaction and at the same time reducing the temperature of the purified flue gas after secondary treatment.

[0028] In a possible implementation manner, two through holes are opened on each of 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; two through holes are also opened on the fourth heat transfer plate 340, namely a first through hole 341 and a second through hole 342. The first through hole 341 is opened 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 opened at the other end of the fourth heat transfer plate 340.

[0029] Specifically, as Figure 2 shown, in order to enable the high-temperature waste gas and the low-temperature waste gas 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 opened on each of the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330, and two pipe through holes are arranged on each of the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330, so that the high-temperature waste gas and the low-temperature waste gas can pass through the first heat transfer plate 310, the second heat transfer plate 320, and the third heat transfer plate 330 whether in the upper layer or the lower layer. Similarly, in order to enable the high-temperature waste gas and the low-temperature waste gas to form a cycle in the upper and lower layers, two through holes are also opened on the fourth heat transfer plate 340, namely a first through hole 341 and a second through hole 342. The first through hole 341 is opened 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 opened at the other end of the fourth heat transfer plate 340.

[0030] Through holes are formed 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 a passage for the exhaust gas to pass through, so that the air flow forms a baffle flow.

[0031] In a possible implementation manner, the catalytic plate 400 is arranged on the upper layer of the mixing unit 200. The top of the catalytic plate 400 is connected to the top of the mixing unit 200, and the bottom of the catalytic plate 400 is 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. There is an included angle α between the catalytic plate 400 and the fourth heat transfer plate 340, and the range of the included angle α is: 20° ≤ α ≤ 30°.

[0032] Specifically, in order to enable a temperature difference to be generated between the exhaust gases of the upper and lower layers, the catalytic plate 400 is arranged at the other end of the third heat transfer plate 330 and the mixing unit 200. In order to allow the high-temperature exhaust gas and the low-temperature exhaust gas to enter the lower layer after passing through the catalytic plate 400, the opening position of the second through hole 342 is located between the catalytic plate 400 and the other side of the mixing unit 200. In order to increase the contact between the high-temperature exhaust gas and the low-temperature exhaust gas and the catalytic plate 400, there is an included angle α between the catalytic plate 400 and the fourth heat transfer plate 340, and the range of the included angle α is: 20° ≤ α ≤ 30°. The temperature of the exhaust gas after passing through the catalytic plate 400 is relatively high and enters the lower layer. Then, through the first heat transfer plate 310, the second heat transfer plate 320 and the third heat transfer plate 330 arranged in the lower layer, the temperature is transferred to the upper layer, so that the temperature of the exhaust gas in the upper layer rises, which is suitable for reacting with the catalytic plate 400 to form heat recovery.

[0033] In a possible implementation manner, it further includes a triple eccentric butterfly valve 500, and the triple eccentric butterfly valve 500 is arranged on the first through hole 341. The setting of the triple eccentric butterfly valve 500 enables it to be directly opened when secondary treatment is not required, and the exhaust gas can be directly discharged from top to bottom. The triple eccentric butterfly valve 500 is adopted because of its sealing technology and unique structural design, which ensure absolutely no leakage during the valve switching process.

[0034] In a possible implementation manner, a high-temperature exhaust gas outlet is arranged at the top of the incinerator, and a low-temperature exhaust gas outlet is arranged at the bottom of the incinerator. A high-temperature exhaust gas inlet and a low-temperature exhaust gas inlet are opened on the mixing unit, and the high-temperature exhaust gas outlet is connected to the high-temperature exhaust gas inlet through a pipeline, and the low-temperature exhaust gas inlet is connected to the low-temperature exhaust gas outlet through a pipeline.

[0035] In a possible implementation manner, it further includes a mode switching system and a control system. Both the mode switching system and the control system are arranged in the mixing unit, and the mode switching system and the control system are electrically connected to each other. Both the mode switching system and the control system are suitable for connecting to an external computer terminal.

[0036] By setting up a mode switching system and a control system, the whole system becomes more intelligent. It can automatically switch between the catalytic treatment mode and the conventional mixing tank mode according to the waste gas treatment requirements without manual intervention. It can monitor parameters such as the composition, flow rate, and temperature of the waste gas in real time, automatically adjust the working parameters according to these parameters, and can also monitor and adjust the heat energy recovery ratio in real time to ensure the best energy saving effect under different working conditions.

[0037] A diversion part 600 is arranged on the heat transfer plate system. The diversion part 600 is a plurality of grooves with a preset length. The diversion part 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 assist the waste gas to flow better in this direction and prevent the formation of dead corners and stagnant situations.

[0038] It should be noted that the number of heat transfer plates arranged at the bottom of the vertical mixing unit 200 is not limited to three, and more than three can be set according to requirements. The number of heat transfer plates arranged at the bottom of the parallel mixing unit 200 is not limited to one, and multiple can also be set as needed. That is, the spacing and number of layers of the heat transfer plates can be set in multiple ways to meet different requirements for heat transfer efficiency and removal rate.

[0039] An efficient regenerative incineration method uses the above-mentioned efficient regenerative incineration device for incineration. The specific steps include: First, the material enters the incinerator through the feed port of the incinerator and is incinerated in the incinerator to generate high-temperature waste gas and low-temperature waste gas; the high-temperature waste gas enters the mixing unit through a pipeline from the high-temperature waste gas outlet, and the low-temperature waste gas enters the mixing unit through a pipeline from the low-temperature waste gas outlet. The high-temperature waste gas and the low-temperature waste gas are mixed in the mixing unit to form mixed waste gas; at this time, the mixed waste gas is in the upper layer of the mixing unit. The mixed waste gas passes through the through holes opened in the upper layer of the first heat transfer plate, the second heat transfer plate, and the third heat transfer plate in sequence, then passes through the catalytic plate, and is heated by the catalyst on the catalytic plate; the heated mixed waste gas enters the lower layer through the second through hole of the fourth heat transfer plate and reaches the emission standard; finally, it is discharged through the exhaust port in the lower layer.

[0040] When the present application is in use: First, put the materials into the incinerator through the feeding port. After being incinerated in the incinerator, high-temperature waste gas and low-temperature waste gas are generated. The high-temperature waste gas enters the pipeline through the high-temperature waste gas outlet at the top of the incinerator and enters the first chamber on the upper layer of the mixing unit through the pipeline. The low-temperature waste gas enters the first chamber on the upper layer of the mixing unit through the low-temperature waste gas outlet at the bottom of the incinerator. The high-temperature waste gas and the low-temperature waste gas are mixed in the first chamber. When the mixed waste gas does not need to be treated, through the control system, open the triple-eccentric butterfly valve, and the mixed waste gas directly enters the eighth chamber and then is directly discharged. When the mixed waste gas needs to be treated, it enters the first chamber. The diversion part on the first heat transfer plate on the upper layer assists the mixed waste gas to pass through the through holes of the upper first heat transfer plate in this direction and enter the second chamber, and then the diversion part of the second heat transfer plate assists the mixed waste gas to pass through the through holes of the upper second heat transfer plate in this direction and enter the third chamber, and then the diversion part of the third heat transfer plate assists the mixed waste gas to pass through the through holes of the upper third heat transfer plate in this direction and enter the fourth chamber. After that, through the catalytic plate and reacting with the catalyst on the catalytic plate, after the temperature of the mixed waste gas rises, it passes through the second through hole and enters the fifth chamber, and then the diversion part on the third heat transfer plate on the lower layer assists the mixed waste gas to pass through the through holes of the lower third heat transfer plate in this direction and enter the sixth chamber, and then the diversion part of the second heat transfer plate on the lower layer assists the mixed waste gas to pass through the through holes of the lower second heat transfer plate in this direction and enter the seventh chamber, and then the diversion part of the first heat transfer plate on the lower layer assists the mixed waste gas to pass through the through holes of the lower first heat transfer plate in this direction and enter the eighth chamber, and then is discharged through the air outlet of the mixing unit.

[0041] Through the synergistic effect of the heat transfer plate system and the catalytic plate, the present application achieves an overall high removal rate, uses the heat generated by the catalytic reaction to heat the upper-layer waste gas, improves the energy utilization efficiency, reduces the operating cost, and through the design of the triple-eccentric butterfly valve, when the equipment does not need to improve the removal efficiency additionally, it can be flexibly converted into a conventional mixing tank for use, and through the setting of the mode switching system and the control system, the whole is made more intelligent, can automatically switch between the catalytic treatment mode and the conventional mixing tank mode according to the waste gas treatment requirements without manual intervention, can monitor parameters such as the composition, flow rate and temperature of the waste gas in real time, and automatically adjust the working parameters according to these parameters, and can monitor and adjust the heat energy recovery ratio in real time to ensure the best energy-saving effect under different working conditions; through the above settings, the present application can save energy while achieving a high removal efficiency of the overall system, and solves the technical problem that the existing incineration device needs to increase fuel consumption to maintain a high treatment efficiency, resulting in increased energy consumption and a high overall energy consumption.

[0042] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
