Description of the invention: [Technical Field of the Invention] The present invention relates to a Regenerative Thermal Oxidizer (RT〇) 'In particular, the present invention proposes a regenerative burner The heat energy recovery method, the heat exchanger, naturally generates gas and flow disturbances by using the high-low temperature density difference smoke effect and the kinetic energy (speed energy) difference effect of the gas flow without using the windmill. The flow 'supplied the heat generated in the combustion chamber of the combustion furnace to the high-efficiency heat energy recovery and reuse function in the closed loop of the combustion chamber, which is different from the open circuit of a conventional technology. [Prior Art] Various countries have a standard for volatile organic solvents (V〇iatHe 〇rganic c〇mp〇unds; v〇Cs), and volatile organic solvents are widely used in the industry. Take the Republic of China as an example. The Bad Insurance Agency announced in August that it has implemented air pollution control and emission standards for semiconductor manufacturing. Its volatile organic waste gas mandates that its v〇Cs reduction rate should be greater than 9〇%. The treatment of organic waste gas is pure, such as heat incineration, catalyst incineration, regenerative combustion, recirculation incineration, activated carbon adsorption, and condensation recovery. The regenerative combustion furnace is provided with a single or a plurality of regenerative beds (Regenerative H+s), and the regenerative beds are filled with heat accumulating materials, so that the volatile organic waste gas flows through the regenerator bed for preheating (this. (the hot material releases heat energy), Then the volatile organic waste gas enters the high temperature oxidation zone (> 800 is burned to medium). At this time, the auxiliary heat energy generated by the fuel nozzle of the burner can provide heat generated by the oxidative decomposition of the components and the VC^Cs component, so that the combustion chamber Maintain a certain temperature - the v〇Cs component of the organic waste gas is completely oxidized to harmless H2〇 and c〇2 in a fixed residence time.

Colagio, U.S. Patent No. 5,297,954, is a conventionally used multi-column regenerative burner. The combustion system contains three sets of regenerator beds, and the energy released by burning v〇Cs is stored by alternate use of three sets of regenerator beds as auxiliary thermal energy. In addition, the high temperature v〇Cs, the work is replaced by the hot father to further recover the heat, so that the exhaust gas can be reduced to a safe temperature before being discharged. The following uses a conventional two-column regenerative burner as an example to illustrate. ° Figure 1 is a schematic diagram of the conventional traditional two-tower regenerative furnace 1 〇 (RT〇) with hot gas bypass-burning 16 (Hot Gas By-Pass) heat recovery. The regenerative combustion furnace 10 mainly comprises two sets of regenerator beds [the first regenerator bed 11 and the second regenerator bed 12], the exhaust gas combustion chamber 13 and its associated exhaust gas inlet and outlet lines, and a flow direction regulating valve. In more detail, the process fan “extracts the organic exhaust gas 2〇 (V0Cs Laden Air) from the exhaust gas source end to the inlet of the double tower regenerative combustion furnace 1〇 (RTO) population called moxibustion (at this time, the fifth flow regulating valve is 〇ff state), there are two modes to enter the reaction in the combustion chamber 13. The first mode: organic exhaust gas 2〇 (hereinafter referred to as VOCS20) enters the pipeline through an intake damper 26, respectively, through the first flow regulating valve to enter the first The second regenerator bed 12 (the second flow regulating valve 22 and the third flow regulating valve 23 at this time is 〇]^[closed]. After passing through the second regenerator bed 12, the VOCs 20 are in the combustion chamber 13 by the fuel nozzle. 14 provides a combustion flame 15 to oxidize V〇Cs20 to form H20 and C〇2. The combustion inside the combustion chamber 13 can reach a temperature of 8 〇〇 9 9 thieves, and the second heat storage during the process The bed can store the heat of the reaction 2: the VOCs2〇 for preheating and then enter the combustion chamber for reaction, so that the energy loss of the flame 15 can be reduced. After the reaction, v〇Cs2〇 (more than 9〇% by water and The carbon dioxide is flowed through the first regenerator bed 11 and the fourth flow direction regulating valve 24 It is discharged to the atmosphere 35 by the blower 27. The second mode: v〇Cs2〇 enters the pipeline from the intake damper 26 via the second flow regulating valve 23 (the first flow regulating valve 21 and the fourth vector regulating valve at this time) 24 is 〇][^ state) enters the first regenerator bed. After passing through the first regenerator bed, v〇Cs2〇 is corrected in the combustion chamber 13 by burning 1293359 埯7·26. The combustion flame 15 oxidizes v〇Cs20 to Η20 and C〇2. In addition to the selection of the first flow regulating valve 21 and the third flow regulating valve 23, the regenerative combustion furnace 1 includes a hot gas bypass pipe 16 connected to the blower 27, and the bypass pipe also has a fifth flow direction control. Valve 25 controls, but this path is only used in the case of a two-column regenerative furnace (RTO) system shutdown, not a normal route for v〇Cs2〇 combustion. Similar to the first mode, in the combustion process, the first heat storage bed u stores the heat of the reaction for preheating and then the VOCs 20 enter the combustion chamber 13 for reaction. The v〇Cs2〇 exhaust gas stream after the reaction passes through the second regenerator bed 12 and the second flow direction regulating valve 22, and is discharged to the atmosphere by the blower 27. The first and second mode timing loops described above are switched to maintain the first regenerator bed, and the first regenerator bed 12 maintains the surface temperature for preheating the reaction gas. Among them, the heat storage materials are mostly composed of ceramic materials. Usually, if the heat energy contained in the exhaust gas V〇CS2〇 is required to be re-oxidized after the oxidation, then a pipe will be connected to the thin line 3G (heatexehan (four), money (four) and green _ connected to the air supply) :27> The cooled V〇Cs2G is discharged to the atmosphere%. v〇Cs2() is transferred to the heat exchanger via the heat exchanger, and the heat exchanger is internally provided with the heat exchange tube bundle 31 to absorb the heat energy, and the heat exchange tube bundle μ is Containing = ^ = f Μ for hot coffee.

That is to say, the airflow disturbance and the flow are naturally generated by the high-low temperature density difference soot effect and the kinetic energy (speed energy) difference effect of the gas flow, so that the heat generated in the combustion chamber of the combustion furnace can be closed again in the combustion chamber. The function of recycling high-efficiency heat energy in the loop (Cl〇se Loop) is different from the open loop of a conventional technology. The re-purpose of the present invention is to increase the tube bundle type dispersion in the horizontal position of the combustion chamber above the storage material in the Lai burner, and construct the heat exchanger in parallel flow mode - the official beam heat exchanger is used for Heat recovery. The double effect of the organic exhaust gas in the smoke and the dynamic pressure difference is made to the portion of the reduced-burning room towel to be fed into and out of the heat exchanger without a burning chamber. First of all, the organic waste gas (VOCs Laden Ai〇) is: a process air is pumped into the combustion furnace to enter the first heat storage bed. The exhaust gas is heated by the first heat storage bed. H2〇 and C〇2 After the combustion process, the organic waste gas then enters the second regenerator bed, and the second regenerator bed stores the heat of the oxidation reaction for heat recovery, and (4) after the preheating, the first two (four) beds pass through the organic purity of the human chamber. The combustion part of the combustion chamber is connected to the high-low temperature density difference.

First, referring to FIG. 2, it is a schematic diagram of a structure 100 of a two-column regenerative combustion furnace (RTO). The regenerative combustion furnace 100 mainly comprises two sets of regenerator beds (the first regenerator bed 11 〇 and the second regenerator bed 120), the exhaust gas combustion chamber 130 and the exhaust gas inlet and outlet lines connected thereto. The inlet and outlet modes of the organic exhaust gas 200 (VOCs Laden Air) are as follows: The process fan 280 extracts organic exhaust gas 2 (VOCs Laden Air; hereinafter referred to as VOCs 200) from the exhaust gas source end and is controlled by an intake dam 260 to enter the combustion furnace pipeline. The second regenerator bed 120 is entered via the first flow regulating valve 210 (the second flow regulating valve 22 and the third flow regulating valve 230 are in the OFF state). After passing through the second regenerator bed 12, v 〇 Cs2 〇〇 in the combustion chamber 13 由 a combustion flame 15 is supplied from the fuel nozzle 140 to oxidize the v 〇 Cs2 形成 to form harmless Ηβ and C〇2. The means for providing the combustion chamber π〇 thermal energy to the fuel nozzle 14〇 may also be an electrothermal or plasma generator. The position of the fuel nozzle 14 can also be at the inlet of the regenerative burner (not shown). The combustion temperature inside the combustion chamber 13〇 can be 65~95〇C or other temperature (depending on the substance to be burned), and the high-temperature exhaust gas after entering the combustion process enters the first heat storage bed 11G. The first-f hot bed ησ can store the heat of the reaction as heat energy recovery, and then it can be used to reduce the combustion after the advanced person _ regenerator bed 11 (^v〇c side, then enter the combustion: ^ to 130) The energy loss of the nozzle 。4〇, wherein the first regenerator bed 12〇 and the first regenerator bed 11 are composed of a honeycomb material, a saddle shape or a cylindrical material, which has a good heat storage capacity and a shouting material. The hole structure can make the VOCs of the reaction pass through the heat bed l2 (ml into the combustion chamber (4). The first flow direction is adjusted to the coffee, the second flow direction is adjusted to the third stage 230, and the fourth flow regulating valve 24_ is connected. The electric or pneumatic valve is configured to be capable of switching between each other to include a hot gas passage port 正 directly above the M k chamber 130 and (10) to cause the high temperature hot gas to naturally lead to the tube bundle heat exchanger 30 located above the combustion chamber 130. (T * bundles heat exchanger) The temperature of the scheme is low, and the VOCs200 after the reverse 1293359 will automatically diffuse into the tube bundle heat exchanger 3〇〇 with lower temperature to form the natural convection flow phenomenon of the smoke with different density. In the case of the exhaust gas density around 300 and the combustion chamber 130, the exhaust gas density after the reaction of v〇Cs2 〇〇 in the tube bundle type heat father 300 is naturally lower than the exhaust gas density in the combustion chamber 13〇, and the tube bundle heat exchanger 300 The position is higher than the combustion chamber 130, so there is a natural convection flow phenomenon with a chimney effect. In addition, the V〇cs200 after the reaction also generates a wind speed away from the first regenerator bed 110 or the second regenerator bed 12 due to the exhaust gas flow. The action of the velocity pressure to enter the tube bundle heat exchanger 3 to perform heat exchange. The above is the focus of the present invention. The tube bundle heat exchanger 300 includes a spiral shape. The heat exchange tube bundle line 3 1〇 and a structure 34 () for the VOCS 200 exhaust gas in and out. The heat exchange tube bundle line 31 is filled with a flowing heat transfer medium 320 for heat exchange operation. The guiding medium 32 includes any fluid of any form such as air, steam, water, and heat medium oil. The spiral hot-forward tube bundle tube 310 may be formed of other shapes of pipes, and the purpose thereof is to increase The contact area of the pipeline in the structure 340 with the high temperature VOCs 200. The heat transfer medium 32 〇 through the heating of the hot gas, high temperature steam, hot water and heat medium oil can be utilized by different methods to achieve thermal resources. For the purpose of recovery, the initial temperature of the heat transfer medium 320 entering the tube bundle heat exchanger 3 is not limited, but needs to be lower than the reaction temperature of the combustion chamber 13 ,, and the heat transfer medium 32 of the official beam heat exchanger 300 is removed. 〇 Control between 18〇~3〇〇 (changes with the requirements of the machine in the factory). It should be noted, however, that the greater the difference between the initial temperature of the heat transfer medium 320 and the temperature of the combustion chamber 13 (), the higher the heat exchange efficiency. In addition, a bypass s 330 (bypass) is added between the inlet end and the exit end of the heat exchange tube bundle line 310, and a sixth flow direction regulating valve 36 〇 is located on the bypass tube 33〇 (as shown in FIG. 2). To regulate the heat transfer medium 32, when too much heat is absorbed, causing the temperature to be too high, the heat transfer medium 32 that has not passed through the official heat exchanger 300 in winter (the heat that does not absorb heat is 1293359 95· 7·26) The conductive medium 320) directly passes through the bypass tube 33 0 to achieve the effect of temperature control. The VOCs 200 after the reaction have the same flow path as the conventional regenerative combustion furnace 10 described above. The first regenerator bed 110 and the fourth flow direction regulating valve 240 are discharged to the atmosphere 350 by the blower 270. - The VOCs 200 can also enter the pipeline from the intake dam 260, enter the first regenerator bed 110 via the third flow regulating valve 230, and preheat the VOCs 200 using the first regenerator bed 110 that has absorbed thermal energy. After passing through the first regenerator bed 110, the VOCs 200 provide a combustion flame 150 in the combustion chamber 130 by the combustion nozzle 140 to oxidize the VOCs 200 to form harmless η20 and CO2. The south temperature exhaust gas after passing through the combustion process enters the second regenerator bed 120, which stores the heat of the reaction as heat energy for preheating and then enters the VOCs 200 of the second regenerator bed 120. The VOCs 200 of the reaction at this time are also subjected to the heat exchange operation in the tube bundle heat exchanger 3 as described above, and will not be repeatedly described herein. After the reaction, the VOCs 200 flow through the second regenerator bed 120 and the second flow direction regulating valve 220, and are discharged to the atmosphere 350 by the blower 270. The second regenerator bed 120 also absorbs part of the heat energy of the VOCs 200, thereby discharging the v〇 in the atmosphere 35〇. The Cs200 can be reduced to safe temperature and concentration emissions. The above-mentioned VOCS200 flow direction (reacting in the first regenerator bed 11 (or the second regenerator bed 120) is periodically switched to maintain the first regenerator bed 110 and the second regenerator bed 12 〇 to maintain a high temperature for preheating the reaction gas. This heat recovery rate can reach 93. Above / 〇, the purification rate can reach 95%~99%. The VOCS 200 has a first flow direction regulating valve 210 and a third flow direction regulating valve 23, and the regenerative combustion furnace 100 includes a bypass pipe connected to the blower 270, and the bypass pipe also has a fifth flow direction control valve 250. Control, but this path is only used in the case of the shutdown of the double-exhaustive combustion furnace 100 (RTO) system, not the normal route of the v〇Cs2〇〇_ burning reaction. The tube bundle heat exchanger 300 of the present invention can be used in any type of combustion furnace or oxidizing furnace or reactor 'without additional additional introduction means, in the embodiment of the invention only the double column regenerative burner Explain it. The reference example of the present invention is a specific embodiment in the field of the invention, and those skilled in the art should be able to understand the meaning of the present invention as appropriate and minor adjustments and applications. The essence of the invention will not be lost. All such applications and adjustments are included in the scope of the patent application. To sum up the specificity of the implementation of the present invention, Cheng has complied with the review of the patents and articles responsible for reviewing the invention as stipulated in the Patent Law, and granted the patent as a prayer.
