Abstract

This invention provides a heat recovery method for a regenerative thermal oxidizer, which includes a tube bundle heat exchanger for recovering the heat energy at the hot air side in a manner of parallel-connecting flow above the horizontal position of a combustion chamber over a heat-storage bed. A combusting path for volatile organic substances in organic waste gas includes the steps of: pumping the substances into the pipeline of the regenerative thermal oxidizer and then into a first heat-storage bed by a ventilator, heating the volatile organic substances by the first heat-storage bed such that the volatile organic substances in the organic waste gas become harmless H2O and CO2 by oxidizing reaction in the combustion chamber. After the combusting processes, the organic waste gas may be introduced into a second heat-storage bed for storing the heat generated by the oxidizing reaction, thereby recovering the heat for pre-heating the organic waste gas before being introduced into the combustion chamber. In the combustion chamber, part of burned organic waste gas of high temperature is smoothly disturbed and introduced into the bundle heat recovering heat exchanger, in a comparatively lower temperature, by means of stack effect of density difference in high/low temperature and kinetic energy difference effect of gas flow continuously, thereby performing heat exchange operation to achieve the objective of recovering heat resource. A circulating heat conductive medium, for absorbing the reacted clean heat energy in the organic waste gas with high temperature by the chance of indirectly contacting with the organic waste gas, is provided in the tube bundle heat recovering heat exchanger. The reacted clean organic waste gas is continuously pumped to discharge into the atmosphere through the second heat-storage bed by a ventilator, in the mean while the temperature of the waste gas has dropped to safe temperature and cleanness suitable for being exhausted into the atmosphere.

The function of achieving high-efficiency thermal energy utilization in the closed loop of the combustion chamber is different from the open loop of a conventional technology. Recycling The hair is regeneratively recovered by the hot gas end. Let the hot gas burn. First, its blower draws a heat storage bed (VOCs). After the process, the organic oxidation reaction bed recovers the heat transfer reaction through the partially bundled tube bundle resource. The dry gas continues to pass through the exhaust gas. Another purpose of Zhiming is to construct organic waste gas in parallel flow of heat storage materials in the combustion furnace. The organic waste gas is automatically paralleled in the combustion chamber of the chimney (V0C; after the heated exhaust gas sent into the combustion furnace, there is an oxidation anti-exhaust gas in the combustion chamber and then enters the first. The heat is re-entered into the combustion chamber for the purpose of organic waste gas, which then borrows kinetic energy (speed energy) for differential heat recovery and heat exchange. It enters the conducting medium through indirect net and high-temperature organic waste from the second heat storage bed, and the temperature has been reduced to safety.

200420857 V. Description of the invention (6) [Embodiment] The present invention produces a heat exchanger on a regenerative combustion furnace to allow organic waste gas to automatically enter and exit the heat exchanger. The embodiment uses a double-tower regenerative combustion furnace as an example to The spirit of the present invention will be described. First, referring to FIG. 2, it is a schematic diagram of the structure 100 of a double-tower regenerative combustion furnace (RT0). The regenerative combustion furnace 100 is mainly composed of two sets of regenerative beds (the first regenerative bed 110 and the second regenerative bed 120), the exhaust gas combustion chamber 150, and the exhaust gas inlet and outlet pipelines connected thereto. The way of entering and exiting the organic waste gas 2 0 (VOCs Laden Air) is as follows: The organic waste gas 2 0 (VOCs Laden Air; hereinafter referred to as VOCs 2 0 0) is controlled by an inlet damper 2 6 0 and enters the combustion furnace pipeline, respectively through the first The one-way control valve 2 1 0 enters the second heat storage bed 1 2 0 (the second flow direction control valve 220 and the third flow direction control valve 2 3 0 at this time are in the OFF state). After passing through the second thermal storage bed 120, VOCs 2 0 0 is provided by a fuel nozzle 140 in the combustion chamber 130 with a combustion flame 1 50 and the VOCs are oxidized to form harmless H20 and C02. The fuel nozzle 140 can provide a device for providing the heat energy of the combustion chamber, which may also be composed of an electric heater or a plasma generator or other facilities capable of providing heat energy, or one of which is not required. The position of the fuel nozzle 140 can also be located at the entrance of the regenerative burner (not shown). The combustion temperature in the combustion chamber of 130 can reach 60 ° C ~ 950 ° C or other temperature (depending on the substance to be burned). The high-temperature exhaust gas after the combustion process enters the first heat storage. In the bed 110, the first heat storage bed 110 can store the heat of the reaction as heat energy for recovery, and is used for preheating and then enters the first heat storage bed 1 1 0

Page 1ί 200420857 V. Description of the invention (7) VOCs 2 0 0, and then enter the combustion chamber 1 30 for reaction. In this way, the energy phase consumption of the combustion nozzle 1 40 can be reduced. The second thermal storage bed j 2 0 and the first thermal storage bed 1 10 are composed of honeycomb-shaped, & horse-shaped or cylindrical ceramic materials, etc., which have good heat storage capacity, and the pore structure of the ceramic material. The reacted organic waste gas VOCs20 can pass through the thermal storage beds 120 and 120 and enter the combustion chamber 130. The first flow direction regulating valve 2 丨 〇, the second vector adjustment valve 2 2 0, the third flow direction regulating valve 2 3 0, and the fourth flow direction regulating valve 2 4 〇 are respectively connected with an electric valve or a pneumatic valve to enable Switch between each other. There are hot gas pipeline channels 17 0 and 160 directly above the combustion chamber. The high temperature hot gas will naturally lead to the tube bundle heat exchanger 300, which is located above the combustion, and its tube bundle type The temperature of the heat exchanger 300 is low, and the VOCs 200 after the reaction will automatically diffuse into the lower temperature tube bundle heat exchanger 300 and form the natural convection flow phenomenon of the chimney effect with different density. As far as the exhaust gas density around the tube bundle heat exchanger 300 and the combustion chamber 130 is concerned, the organic exhaust gas VOCs 2 0 0 in the tube bundle heat exchanger 3 0 0 is naturally lower than the combustion chamber 1 3 The exhaust gas density within 0, and the tube bundle heat exchanger 300 is higher than the combustion chamber 130, so the natural convection flow phenomenon with a chimney effect exists naturally. In addition, the reacted organic waste gas V 0 C s 2 0 will also enter the tube bundle due to the influence of the velocity pressure of the wind speed leaving the first heat storage bed 1 10 or the second heat storage bed 1 2 0 caused by the flow of the waste gas. The heat exchanger 300 performs heat exchange operation. This is the focus of the present invention. The tube-bundle heat exchanger 300 includes a spiral-shaped pipe 3 10 and a structure 340 for VOCs 2 0 exhaust gas to enter and exit. Heat exchange tube bundle pipe 310

The heat transfer medium 3 2 0 that can be added includes: air, steam, water, heat medium oil, etc., in any form of fluid. The helical pipe 3 10 can be composed of other shapes of pipes, and the purpose is to increase the contact area of the pipe in the structure between 3 40 and the high-temperature VOCs 2000. The heat gas, high-temperature steam, hot water, and heat medium oil formed after heating can be used in different ways to achieve the purpose of heat resource recovery. The initial temperature of the heat conduction medium 3 2 0 entering the tube bundle heat exchanger 300 is not limited, but it needs to be lower than the reaction temperature of combustion to 300, and the heat conduction medium of the tube bundle heat exchanger 300 3 2 0 is controlled between 180 ° ~ 300 ° C (changes with the requirements of the machine in the factory). However, it can be noticed that the larger the difference between the initial temperature of the heat conducting medium 32 and the temperature of the combustion chamber 300 is, the higher the heat exchange efficiency is. In addition, a bypass pipe 3 3 0 (bypass) is added to the pipe 310 of the heat exchange tube bundle in and out of the tube bundle heat exchanger 300, and a sixth flow regulating valve 33 is located on the bypass officer (as shown in Figure 2). (Shown) Used to adjust the heat conduction medium 32〇 When too much heat energy is absorbed and the temperature is too high, the heat conduction medium 3 2 0 (the heat conduction medium without heat absorption ^ 32〇 / The through pipe 3 3 0 achieves the effect of temperature control. &Amp; Same as the organic waste gas VOCs 20 after the reaction of the traditional thermal storage type and the fourth flow direction regulating valve 〇 The same way the combustion furnace 1 〇 flows through the first thermal storage bed 1 0 240, It is discharged into the atmosphere by the blower 2 70. The VOCS20 0 can also enter the pipeline through the air inlet valve 26 and enter the first heat storage bed through the third flow direction adjustment 阙 230. It can be used to preheat V by absorbing the heat storage bed uo. 〇Cs200. After passing the first heat storage bed ', u〇s

The reaction v0Cs2 0 0 at this time will also enter the & beam heat parent switch 300 for heat exchange action as described above, and will not be repeated here. After the reaction, the VOCs 2 0 0 flows through the second heat storage bed 12 0 and the second flow regulating valve 2 2 0 and is discharged into the atmosphere by the blower 2 70. The second heat storage bed 2 2 will also absorb part of the heat energy of VOCs 2 0 and is discharged. VOCs 2 0 0 in the atmosphere 3 5 can be reduced to safe temperature and concentration emissions. The flow direction of the above-mentioned organic waste gas V0Cs20 0 (reacting on the first thermal storage bed 110 or the second thermal storage bed 120) is periodically switched to maintain the first thermal storage bed and the second thermal storage bed to maintain high temperatures for the purpose of predicting Thermal reaction gas, so that the thermal energy recovery rate can reach more than 93%, and the purification rate can reach 95% to 99%.
