New description: [New technical field] This is an energy-saving device for a nitrogen-containing and/or sulfur-containing volatile organic matter incineration treatment system, especially an additional heat exchanger that will be purified by a repurification unit. After the purification of the gas stream, the heat is recycled again before the designer of the atmosphere. [Prior Art] Organic solvents, widely used in life and production, are easily volatilized into gases at room temperature, so they are also known as Volatile Organic Compounds (VOCs). Most VOCs are toxic to humans and must be toxic. In addition, the air quality monitoring data shows that ozone generated by the reaction of odor precursors such as VOCs and NOx with light has replaced the suspended particles as a major pollutant affecting the air pollution index (PSI), so the regulation is strengthened. VOCs emissions are one of the current air pollution control priorities; however, using incinerators as one of the VOCs waste gas treatment methods, the removal rate of VOCs under appropriate conditions can reach over 99%, and the products after combustion are usually water, carbon dioxide, Nitrogen oxides, sulfur oxides, etc., are a method for effectively treating VOCs and odors contained in exhaust gas. Sub-press, if an incinerator is used to incinerate nitrogen-containing and/or sulfur-containing volatile organic compounds (such as those listed below), it must be added to the downstream end of the incinerator (10) as shown in the first figure. The denitrification and/or desulfurization repurification unit (20) discharges the derivatized pollutants (nitrogen oxides (NOx) or/and sulfur oxides (SOx)) after incineration combustion to the atmosphere; However, due to the repurification unit (20) used for denitration and/or desulfurization, the operating temperature has the lowest temperature limit -3- M373455 system 'Generally must be above 20 (TC is preferably 300. (: ~400) Between °C), in order to obtain better purification efficiency, especially if the derivative pollutant is sulfur oxide (SOx), then there must be attention to the problem of acid corrosion dew point; and the repurification technology of this derivative pollutant is known and common. The technology will not be described here; however, the flow of gas through the repurification unit (2〇) usually controls the outlet gas temperature of the incinerator (1〇) to the operating temperature required by the repurification unit (20) ( As above, above 200 ° C), 俾 to achieve the effect of re-purification; The temperature of the purge gas discharged from the unit (20) is still very high (possibly between 200 ° C and 400 ° C), which can be reused for heat recovery. Furthermore, in order to prevent high boiling point volatile organic residues on the inlet side of the incinerator In the event of a shutdown smoldering problem or a Tar phenomenon, general incinerators (especially regenerative incinerators) are required to periodically raise the temperature of the gas stream for the incinerator to perform a high-temperature Bake out process. Residual high-boiling volatile organic compounds are thermally desorbed.

It has the effect of adding a heat exchanger to save energy. Another purpose of this creation is to enhance the repurification efficiency and the effect of heat drying and decontamination. In order to achieve the above-mentioned functions, the structural features of the creation include: an incinerator connected to the air intake pipe and the exhaust pipe; a re-purification unit disposed downstream of the exhaust pipe of the incinerator, through which the incinerator is to be passed The incineration and combustion of the derivatized pollutants is re-purified, and the purified gas stream is discharged to the atmosphere by the discharge pipe; and a heat exchanger that recovers the heat from the discharge pipe. - In addition, the incinerator is a recovery incinerator, a regenerative incinerator or a regenerative accumulator. The incinerator has a fan disposed on the air intake pipe or the exhaust pipe. The heat exchanger is a shell or plate or plate heat exchanger. The repurifying unit is one or a combination of denitration or/and desulfurization equipment. The air inlet pipe or the discharge pipe is alternatively arranged to avoid the bypass pipe of the heat exchanger, and the first thermometer and the second thermometer are disposed at the inlet and the outlet of the incinerator, and the detected temperature is transmitted via the signal A controller adjusts the opening of the bypass control valve. [Embodiment] First, please refer to the second figure. The creation system includes: an incinerator (10) connected with an air inlet pipe (12) and an exhaust pipe (13), and a fan (11) is arranged. The air introducing pipe (12) or the exhaust pipe (13) is used for introducing and incinerating volatile organic compounds; and the incinerator (1〇) is a Recuperative Thermal Oxidizer and a regenerative burning M373455 Regenerative Thermal Oxidizer or rotary regenerative incinerator; a repurification unit (20) disposed downstream of the exhaust pipe (13) of the incinerator (10) for incineration combustion through the incinerator (10) The post-derivative pollutants (nitrogen oxides or/and sulfur oxides) are re-purified, and the purified gas stream is discharged to the atmosphere by the discharge pipe (21) and the smoke letter (22), and the re-purification unit (20) is One or a combination of denitration and/or desulfurization equipment; and a heat exchanger (30), which may be a shell or plate heat exchanger, and the air intake pipe (12) recovers heat energy from the discharge pipe (21) By. In addition, the air inlet pipe (12) or the discharge pipe (21) is alternatively disposed to avoid the bypass pipe (121 or 211) of the heat exchanger (30) for controlling flow through the bypass pipe (121 or 211) The flow rate of the gas, adjusting the gas flow rate into the heat exchanger (30) for heat recovery 'by adjusting the temperature of the exhaust gas stream introduced into the incinerator (1〇) can further limit the inlet of the incinerator (10) And the outlet temperature is high and low; therefore, the first thermometer (31) and the second thermometer (32) can be disposed at the inlet and the outlet of the incinerator (10) to detect the inlet and outlet of the incinerator (1〇) The temperature 'and the temperature signal adjusts the opening of the control valve (122 or 212) of the bypass pipe (121 or 211) via a controller (33), and adjusts the heat entering the heat exchanger (30) for heat recovery. The flow rate, in turn, controls the outlet temperature of the incinerator (10) to be between 300 ° C and 400 ° C. Based on the composition of the heat exchanger (30) added by the prior art, the purified gas stream purified by the repurifying unit (2〇) is subjected to heat recovery and then discharged to the atmosphere; however, according to The test results of the actual machine can be used to introduce the final discharge temperature of the purified gas stream, and then add the heat exchanger (3 〇) to the original incineration furnace (1〇) from the original 350 ° C to 170 ° C. The exhaust gas flow temperature of 6- M373455 is raised from the original 50 °C to 23 (TC, which saves the fuel (energy) required for the incinerator (10), and has energy-saving effect; and can further control the incinerator (10) The high and low values of the population and the outlet temperature, thereby improving the repurification efficiency of the repurifying unit (10), and preventing the residual problem of the volatile organic compounds at the inlet side of the incinerator (10), having a re-purification efficiency and thermal desorption The effect of purification. • In summary, the structure revealed by this creation is nothing for the past, and it can indeed achieve the improvement of efficacy' and can be used for industrial Xiang, fully in line with the new requirements, pray for your review committee.
