A regenerative thermal ignition (RTI) waste gas treatment device

Abstract

This invention relates to the field of waste gas treatment equipment technology, and discloses a regenerative thermal incineration waste gas treatment device, including a support frame. Three regenerative chambers are fixedly connected to the top of the support frame, and a common combustion chamber is fixedly connected to the top of the three regenerative chambers. This invention addresses the problem of local overheating and thermal shock cracking of ceramic honeycomb. An auxiliary mechanism and a pressure mechanism are set inside the device. After the waste gas is purified, a hydraulic press pushes a hydraulic push rod upward, which in turn moves the highest fixed frame two upward. As the hydraulic push rod continues to move upward, the six fixed frames two will separate, and the air inlet pipe will generate a negative pressure suction force, forcing the purified high-temperature gas in the common combustion chamber to flow downward and heat the honeycomb ceramic two and honeycomb ceramic one. This causes multiple sets to separate, allowing the oxygen remaining inside the honeycomb ceramic one and honeycomb ceramic two to diffuse outward at once, while reducing the length of the "combustion channel" and effectively reducing the probability of combustion and explosion.

Description

Technical Field

[0001] This invention relates to the field of waste gas treatment equipment technology, specifically a regenerative thermal incineration waste gas treatment device. Background Technology

[0002] Regenerative thermal oxidizers treat low-to-medium concentration organic waste gas using thermal oxidation, efficiently recovering heat through a ceramic regenerative bed. The equipment mainly consists of a ceramic regenerative bed, an automatic reversing valve, a combustion chamber, and a control system. Through alternating switching between the three chambers, it completes a cycle of "regenerative preheating → high-temperature oxidation → exothermic regeneration → cleaning and resetting." The ceramic bed typically uses high-specific-heat-capacity, high-thermal-conductivity honeycomb ceramics or ceramic packing, enabling rapid heat absorption and release, significantly reducing auxiliary fuel consumption, and achieving self-heating operation under high-concentration conditions. After a regenerative chamber completes heat release, the system enters a cleaning and resetting process. Clean, high-temperature gas is used to reverse-purge the regenerative chamber that has just finished exhausting, sending residual waste gas within the ceramic body to the combustion chamber or the inlet end, preventing VOC short-circuiting escape, and simultaneously removing residual organic matter, oil, and condensate from the ceramic surface, avoiding excessively high local concentrations, ceramic carbon buildup, and decreased heat exchange efficiency. To mitigate the cracking of the ceramic honeycomb caused by thermal expansion and contraction, multiple ceramic honeycombs are typically spliced ​​together inside the equipment.

[0003] Backflushing typically employs high-temperature purification of flue gas at the top of the combustion chamber. Ceramic honeycomb structures are prone to carbon buildup during operation, with a self-ignition temperature of approximately 300°C, while the flue gas temperature at the top of the combustion chamber exceeds 700°C. The backflushing gas still contains residual oxygen, which disturbs the stagnant zones within the ceramic structure during purging, entraining surrounding oxygen-rich gas. Simultaneously, the narrow channels of the ceramic honeycomb form "micro-combustion channels," where local temperatures can surge to 900–1100°C, causing localized overheating and thermal shock cracking. To address these problems, this invention is proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a regenerative thermal ignition (RTI) waste gas treatment device, including a support frame, three regenerative chambers fixedly connected to the top of the support frame, a common combustion chamber fixedly connected to the top of the three regenerative chambers, an air inlet pipe penetrating the bottom of the three regenerative chambers, and a support mesh fixedly connected to the inner wall of the through hole of the support frame, and further including: The auxiliary mechanism is fixedly installed on the top of the bracket; The pressure mechanism is fixedly mounted on top of the auxiliary mechanism; The external exhaust gas enters the common combustion chamber in an orderly manner through three intake pipes. The flame inside the common combustion chamber will carry out a high-temperature oxidation reaction on the exhaust gas. After completing a single exhaust gas treatment, the high-temperature gas inside the common combustion chamber will flow downwards and pass through the next heat storage chamber to heat the ceramic inside.

[0005] Preferably, the auxiliary mechanism includes: A fixing component is fixedly installed on the top of the bracket; A sliding component is slidably mounted on the inner wall of the fixed component; The sliding component can slide up and down along the inner wall of the fixed component, which is fixed to the top of the bracket.

[0006] Preferably, the pressure mechanism includes: A limiting component is fixedly positioned on top of the sliding component; The push component is fixedly mounted at the bottom of the bracket; Before use, the bottom end of the pushing component needs to be fixedly connected to the ground. When the high-temperature gas heats the ceramic on the inner wall of the heat storage chamber, the pushing component drives the sliding component and the limiting component to extend.

[0007] Preferably, the fixing assembly includes a fixing frame 1 fixedly connected to the top of the bracket, a sliding cylinder 1 fixedly connected to the top of the fixing frame 1, a limiting ring 1 fixedly connected to the inner wall of the through hole of the fixing frame 1, and a honeycomb ceramic 1 placed on the top of the limiting ring 1. Among them, the cross-section of the honeycomb ceramic is smaller than the cross-section of the inner hole of the fixing frame.

[0008] Preferably, the sliding assembly includes a sliding rod 1 slidably connected to the inner wall of the sliding cylinder 1, and a fixing frame 2 is fixedly connected to the top of the sliding rod 1; The outer wall of the sliding rod is slidably connected to the inner wall of the sliding cylinder, and there are six fixed frames, which are stacked one on top of the other.

[0009] Preferably, the limiting component includes a slide cylinder two fixedly connected to the top of the fixing frame two, a limiting ring two fixedly connected to the inner wall of the through hole of the fixing frame two, and a honeycomb ceramic two placed on the top of the limiting ring two; Among them, the cross-section of the second honeycomb ceramic is smaller than the inner hole cross-section of the second fixed frame. Under normal conditions, the bottom end of the first sliding rod is in contact with the second fixed frame below. In this state, there is a gap between the upper and lower two honeycomb ceramics. The top of the second fixed frame at the highest position does not have the second sliding cylinder.

[0010] Preferably, the pushing component includes a hydraulic press fixedly connected to the side wall of the support, and a hydraulic push rod is fixedly connected to the output end of the hydraulic press; The end of the hydraulic push rod furthest from the hydraulic press is fixedly connected to the outer wall of the second fixed frame at the highest position.

[0011] Preferably, the outer wall of the six sets of sliding rods is slidably connected to the inner wall of the lower sliding cylinder. When the hydraulic press drives the hydraulic push rod to slide upward, the hydraulic push rod will cause the six fixed frames to slide.

[0012] The present invention has the following beneficial effects: (1) This invention addresses the problem of thermal shock cracking caused by localized overheating in ceramic honeycomb structures. An auxiliary mechanism and a pressure mechanism are installed inside the equipment. After the exhaust gas is purified, the hydraulic press pushes the hydraulic push rod upwards, which in turn moves the highest fixed frame two upwards. As the hydraulic push rod continues to move upwards, the six sets of fixed frames two separate from each other. Figure 7 The state becomes Figure 9 In this state, the intake pipe creates a negative pressure suction force, driving the high-temperature purified flue gas in the shared combustion chamber downwards to heat the honeycomb ceramic layer 2 and honeycomb ceramic layer 1. After the multiple layers of ceramic bodies separate, the residual oxygen inside the ceramics can be discharged all at once, while shortening the length of the "combustion channel" and effectively reducing the probability of combustion explosion.

[0013] (2) This invention utilizes the increased spacing of the two fixing frames described above. When the high-temperature gas at the top flows from top to bottom and passes through the honeycomb ceramic, as... Figure 10 As shown, after the high-temperature flue gas passes through the honeycomb ceramic along path K, part of the airflow diffuses laterally along path L; the flowing airflow can carry away the fine carbon deposits in the ceramic channels, thus achieving carbon deposit cleaning.

[0014] (3) As some of the high-temperature gas diffuses outward through L, the air pressure between the two honeycomb ceramics disappears. At this time, under the influence of the negative pressure suction force of the bottom air inlet pipe, the high-temperature air outside will fill the space between the two honeycomb ceramics again through path M. As the spacing between the two honeycomb ceramics expands, the untreated waste gas remaining inside the pores of the two honeycomb ceramics will diffuse outward through path L. Through the application of the above components, the untreated waste gas remaining inside the pores of the two honeycomb ceramics can be effectively removed.

[0015] (4) In this invention, because the two honeycomb ceramics are separated from each other, the high-temperature air outside can flow along the gaps between the two honeycomb ceramics. Compared with the conventional stacked design, because the inner wall of the pores of the two honeycomb ceramics has carbon deposits, the carbon deposits will absorb some heat and then conduct it to the position of the two honeycomb ceramics through thermal radiation. As the gaps between the two honeycomb ceramics are separated, the high-temperature airflow entering from position M will directly contact the upper and lower surfaces of the two honeycomb ceramics, increasing the heating area of ​​the two honeycomb ceramics and increasing the heating rate of the two honeycomb ceramics in the same time.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1-7This invention relates to a regenerative thermal ignition (RTI) waste gas treatment device, comprising a support frame 13, three regenerative chambers 14 fixedly connected to the top of the support frame 13, a common combustion chamber 15 fixedly connected to the top of the three regenerative chambers 14, an air inlet pipe 16 penetratingly connected to the bottom of the three regenerative chambers 14, and a support mesh 17 fixedly connected to the inner wall of the through hole of the support frame 13, and further comprising: Auxiliary mechanism 1 is fixedly installed on the top of bracket 13; Pressure mechanism 2 is fixedly installed on top of auxiliary mechanism 1; External exhaust gas enters the common combustion chamber 15 in an orderly manner through three intake pipes 16. The flame inside the common combustion chamber 15 will burn the exhaust gas. After completing a single exhaust gas treatment, the high-temperature gas inside the common combustion chamber 15 will flow downward and pass through the next heat storage chamber 14 to heat the ceramic inside.

[0021] Auxiliary mechanism 1 includes: Fixing component 11 is fixedly mounted on the top of bracket 13; The sliding component 12 is slidably disposed on the inner wall of the fixed component 11; The sliding component 12 can slide up and down along the inner wall of the fixed component 11, which is fixed to the top of the bracket 13.

[0022] Pressure mechanism 2 includes: Restriction component 21 is fixedly disposed on the top of sliding component 12; Push component 22 is fixedly installed at the bottom of bracket 13; Before use, the bottom end of the pushing component 22 needs to be fixedly connected to the ground. When the high-temperature gas heats the ceramic on the inner wall of the heat storage chamber 14, the pushing component 22 drives the sliding component 12 and the limiting component 21 to extend.

[0023] Example 2, please refer to Figures 3-10 The present invention is a heat storage incineration waste gas treatment device. Based on the first embodiment, the fixing component 11 includes a fixing frame 111 fixedly connected to the top of the support 13, a sliding cylinder 112 fixedly connected to the top of the fixing frame 111, a limiting ring 113 fixedly connected to the inner wall of the through hole of the fixing frame 111, and a honeycomb ceramic 114 placed on the top of the limiting ring 113. Among them, the cross-section of the honeycomb ceramic-114 is smaller than the cross-section of the inner hole of the fixing frame-111.

[0024] The sliding assembly 12 includes a sliding rod 121 that is slidably connected to the inner wall of the sliding cylinder 112, and a fixing bracket 122 is fixedly connected to the top of the sliding rod 121. As some of the high-temperature gas diffuses outward through L, the air pressure between the honeycomb ceramics 213 disappears. At this time, under the influence of the negative pressure suction force of the bottom air inlet pipe 16, the external high-temperature air will fill the space between the honeycomb ceramics 213 again through path M. As the spacing between the honeycomb ceramics 213 increases, the untreated waste gas remaining inside the pores of the honeycomb ceramics 213 will diffuse outward through path L. Through the application of the above components, the untreated waste gas remaining inside the pores of the honeycomb ceramics 213 is effectively removed.

[0025] The limiting component 21 includes a slide cylinder 211 fixedly connected to the top of the fixing frame 2 122, a limiting ring 212 fixedly connected to the inner wall of the through hole of the fixing frame 2 122, and a honeycomb ceramic 213 placed on the top of the limiting ring 212. To address the issue of localized overheating and thermal shock cracking in ceramic honeycomb, an auxiliary mechanism 1 and a pressure mechanism 2 are installed inside the equipment. Under normal conditions, the bottom of the second limiting ring 212 is in contact with the top of the first honeycomb ceramic 114, while the top of the second honeycomb ceramic 213 is in contact with the bottom of the upper limiting ring 212. When external exhaust gas enters the heat storage chamber 14 through the inlet pipe 16, the exhaust gas will pass through the high-temperature second honeycomb ceramic 213 and the first honeycomb ceramic 114, and the temperature of the exhaust gas will be increased through thermal radiation.

[0026] The pushing component 22 includes a hydraulic press 221 fixedly connected to the side wall of the bracket 13, and a hydraulic push rod 222 is fixedly connected to the output end of the hydraulic press 221. After the exhaust gas is purified, the hydraulic press 221 pushes the hydraulic push rod 222 upward, which in turn moves the highest fixed frame 122 upward. Simultaneously, the fixed frame 122 moves the sliding rod 121 along the inner wall of the sliding cylinder 211. Ultimately, the upper fixed frame 122, through the sliding rod 121 and the sliding cylinder 211, moves the lower fixed frame 122 upward in sync. As the hydraulic push rod 222 continues to move upward, the six fixed frames 122 will separate. Figure 7 The state changes to Figure 9 In this state, the intake pipe 16 will generate negative pressure suction force, forcing the purified high-temperature gas in the common combustion chamber 15 to flow downwards and heat the honeycomb ceramic 213 and honeycomb ceramic 114. Through the application of the above components, multiple sets of upper and lower separation are achieved, allowing the oxygen remaining inside the honeycomb ceramic 114 and honeycomb ceramic 213 to diffuse outwards at once, while reducing the length of the "combustion channel" and effectively reducing the probability of combustion explosion.

[0027] The outer wall of the six sets of sliding rods 121 is slidably connected to the inner wall of the lower sliding cylinder 211; Utilizing the increased spacing of the aforementioned fixing bracket 2 122, when the high-temperature gas at the top flows from top to bottom and passes through the honeycomb ceramic 2 213, as... Figure 10 As shown, after the K path passes through the honeycomb ceramic 213, there is another layer of honeycomb ceramic 213 at the bottom. This causes some of the high-temperature gas to diffuse outward along the L path. When the high-temperature gas passes through the pores inside the honeycomb ceramic 213, the high-temperature flowing air will drive the fine carbon deposits in the pores of the honeycomb ceramic 213 to diffuse outward through the L path, effectively removing the fine carbon deposits remaining inside the honeycomb ceramic 213.

[0028] One specific application of this embodiment is as follows: During use, external exhaust gas enters the common combustion chamber 15 through one of the intake pipes 16, and the flame inside the common combustion chamber 15 will burn the exhaust gas. After completing a single exhaust gas treatment, the high-temperature gas inside the common combustion chamber 15 will flow downward and pass through the next heat storage chamber 14 to heat the ceramic inside.

[0029] To address the issue of thermal shock cracking due to localized overheating in the ceramic honeycomb structure, an auxiliary mechanism 1 and a pressure mechanism 2 are installed inside the equipment. Under normal conditions, the bottom of the second limiting ring 212 is in contact with the top of the first honeycomb ceramic 114, while the top of the second honeycomb ceramic 213 is in contact with the bottom of the upper limiting ring 212. When external exhaust gas enters the heat storage chamber 14 through the inlet pipe 16, the exhaust gas passes through the high-temperature second honeycomb ceramic 213 and the first honeycomb ceramic 114, increasing the exhaust gas temperature through thermal radiation. After the exhaust gas is purified, the hydraulic press 221 pushes the hydraulic push rod 222 upward, which in turn moves the highest fixed frame 122 upward. Simultaneously, the fixed frame 122 moves the sliding rod 121 along the inner wall of the sliding cylinder 211. Ultimately, the upper fixed frame 122, through the sliding rod 121 and the sliding cylinder 211, moves the lower fixed frame 122 upward in sync. As the hydraulic push rod 222 continues to move upward, the six fixed frames 122 will separate. Figure 7 The state changes to Figure 9 In this state, the intake pipe 16 will generate negative pressure suction force, forcing the purified high-temperature gas in the common combustion chamber 15 to flow downwards and heat the honeycomb ceramic 213 and honeycomb ceramic 114. Through the application of the above components, multiple sets of upper and lower separation are achieved, allowing the oxygen remaining inside the honeycomb ceramic 114 and honeycomb ceramic 213 to diffuse outwards at once, while reducing the length of the "combustion channel" and effectively reducing the probability of combustion explosion. Utilizing the increased spacing of the aforementioned fixing bracket 2 122, when the high-temperature gas at the top flows from top to bottom and passes through the honeycomb ceramic 2 213, as... Figure 10As shown, after the K path passes through the honeycomb ceramic 213, there is another layer of honeycomb ceramic 213 at the bottom. This causes some of the high-temperature gas to diffuse outward along the L path. When the high-temperature gas passes through the pores inside the honeycomb ceramic 213, the high-temperature flowing air will drive the fine carbon deposits in the pores of the honeycomb ceramic 213 to diffuse outward through the L path, effectively removing the fine carbon deposits remaining inside the honeycomb ceramic 213. In addition, as some high-temperature gas diffuses outward through L, the air pressure between the honeycomb ceramics 213 disappears. At this time, under the influence of the negative pressure suction force of the bottom air inlet pipe 16, the external high-temperature air will fill the space between the honeycomb ceramics 213 again through path M. As the spacing between the honeycomb ceramics 213 increases, the untreated waste gas remaining inside the pores of the honeycomb ceramics 213 will diffuse outward through path L. Through the application of the above components, the untreated waste gas remaining inside the pores of the honeycomb ceramics 213 is effectively removed.

[0030] Because the honeycomb ceramics 213 are separated from each other, high-temperature external air can flow through the gaps between them. Compared to the conventional stacked design, the inner wall of the honeycomb ceramics 213 has carbon deposits, which absorb some heat and then conduct it to the honeycomb ceramics 213 through thermal radiation. As the gaps between the honeycomb ceramics 213 separate, the high-temperature airflow entering from position M will directly contact the top and bottom surfaces of the honeycomb ceramics 213, increasing the heating area of ​​the honeycomb ceramics 213 and improving the heating rate of the honeycomb ceramics 213 in the same time.

[0031] After cleaning the second cellar ceramic 213 and the first cellar ceramic 114, the hydraulic press 221 moves downward with the hydraulic push rod 222, forcing multiple second cellar ceramics 213 from... Figure 9 The state changes to Figure 7 The state.
