Description

Technical Field

[0001] This utility model relates to the field of chemical system technology, and in particular to a system for the synergistic treatment of organic waste gas. Background Technology

[0002] Currently, the mainstream methods for treating organic waste gas in industry are catalytic combustion, regenerative thermal combustion, and adsorption. Catalytic combustion and regenerative thermal combustion require large investments in the construction of specialized furnaces and kilns, and also consume additional energy during operation. Adsorption requires regular replacement of the adsorbent, which generates secondary pollutants—waste adsorbent. The overall efficiency of all three methods is not high.

[0003] Therefore, there is currently a lack of an industrial treatment solution for organic waste gas that can improve overall efficiency. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a system for the synergistic treatment of organic waste gas, thereby improving the overall efficiency of industrial organic waste gas treatment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: In a first aspect, this utility model provides a system for the synergistic treatment of organic waste gas, including a gas-liquid separator and a sulfur incinerator. The lower tank of the gas-liquid separator is connected to an organic tail gas pipe, and its bottom is connected to a concentrated liquid discharge pipe. Its top is connected to the first side of the sulfur incinerator via an organic tail gas inlet pipe and an organic tail gas burner. The first side of the sulfur incinerator is also connected to a sulfur gun. The side of the sulfur gun away from the sulfur incinerator is connected to a liquid sulfur pipeline. The dedicated air inlet of the sulfur incinerator is connected to an air pipeline. A flue gas discharge device is provided on the second side of the sulfur incinerator.

[0006] The beneficial effects of this invention are as follows: Organic waste gas undergoes a gas-liquid separation process in a gas-liquid separator to remove any entrained liquids. The waste gas is then burned in a sulfur incinerator via an organic waste gas burner. An additional organic waste gas combustion pipeline is added to the existing sulfur incinerator. Utilizing the high-temperature combustion environment of sulfur within the incinerator, harmful substances in the organic waste gas are decomposed into harmless carbon dioxide and water, achieving compliant treatment. Therefore, this invention requires only a small addition to existing sulfuric acid production equipment to achieve industrial treatment of organic waste gas, simultaneously treating harmful substances and reducing environmental pollution, thereby improving the overall efficiency of industrial organic waste gas treatment.

[0019] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0020] Example 1 Please refer to Figure 1 A system for co-processing organic waste gas includes a gas-liquid separator 10, a sulfur incinerator 4, and a waste heat boiler 19. The lower tank of the gas-liquid separator 10 is connected to an organic tail gas pipe 9, and its bottom is connected to a concentrated liquid discharge pipe 17. Its top is connected to the first side of the sulfur incinerator 4 via an organic tail gas inlet pipe 12 and an organic tail gas burner 15. The first side of the sulfur incinerator 4 is also connected to a sulfur gun 8. The side of the sulfur gun 8 away from the sulfur incinerator 4 is connected to a liquid sulfur pipeline 5. That is, organic tail gas and sulfur are introduced into the first side of the sulfur incinerator 4. The dedicated air inlet of the sulfur incinerator 4 is connected to an air pipeline 1, and a flue gas discharge device is provided on the second side of the sulfur incinerator 4.

[0021] In this embodiment, the flue gas discharge device includes a three-way bell valve 18. One side of the lower valve body of the three-way bell valve 18 is connected to the second side of the sulfur incinerator 4, and the upper valve body is connected to a flue gas conveying pipe 25. The other side of the lower valve body of the three-way bell valve 18 is connected to the head of the waste heat boiler 19. A condensate discharge pipe 22 is connected to the lower part of the tail of the waste heat boiler 19, and a condensate discharge valve 21 is installed on the condensate discharge pipe 22. A steam drum 20 is connected to the top of the waste heat boiler 19, and the upper part of the tail of the waste heat boiler 19 is connected to the upper valve body of the three-way bell valve 18 through a flue gas regulating pipe 23. An electric flue gas regulating valve 24 is installed on the flue gas regulating pipe 23. Thus, this utility model can fully utilize the heat energy generated by the decomposition of organic matter in the organic waste gas, converting it into useful steam and realizing waste heat recovery.

[0022] In this embodiment, a demister 11 is installed above the interior of the gas-liquid separator 10. The demister 11 further removes fine droplets from the organic exhaust gas to achieve a better gas-liquid separation effect.

[0023] In this embodiment, each pipeline is equipped with a corresponding detector and regulating valve to monitor and regulate the gas or liquid in the pipeline. Specifically, the flue gas delivery pipe 25 is equipped with a sampling valve 26 and a remote thermometer 28, and the sampling valve 26 is connected to an online flue gas analyzer 27. The air pipeline 1 is equipped with an air flow meter 2 and an electric air regulating valve 3. The liquid sulfur pipeline 5 is equipped with a sulfur flow meter 6 and a liquid sulfur regulating valve 7. The organic tail gas inlet pipe 12 is equipped with an organic tail gas flow meter 13 and an organic tail gas pneumatic regulating valve 14. The concentrate discharge pipe 17 is equipped with a concentrate discharge valve 16.

[0024] In summary, the working process of this embodiment is as follows: (1) Organic exhaust gas enters gas-liquid separator 10 through organic exhaust gas pipe 9. Liquid that may be carried in the organic exhaust gas is separated by the concentrate in gas-liquid separator 10, and fine droplets in the organic exhaust gas are further removed by demister 11.

[0025] (2) The organic tail gas after liquid separation is burned in sulfur incinerator 4 through organic tail gas burner 15. By adding liquid sulfur pipeline 5 and sulfur gun 8 on the basis of sulfur incinerator 4, an organic waste gas combustion pipeline is added. By utilizing the high temperature combustion environment of sulfur in sulfur incinerator 4 at about 1000℃, the harmful substances in organic waste gas are decomposed into harmless carbon dioxide and water to achieve the standard treatment of organic waste gas.

[0026] (3) At the same time, the organic matter in the harmful gas will release heat when it decomposes at high temperature. This heat is transferred to the waste heat boiler 19 to generate steam, and the gas in the waste heat boiler 19 is transferred to the upper valve body of the three-way bell valve 18 through the flue gas regulating pipe 23 so as to be discharged through the flue gas conveying pipe 25.

[0027] Therefore, in this embodiment, the organic waste gas is separated into liquid by a gas-liquid separator 10 and a demister 11, and then burned in a sulfur incinerator 4 by an organic waste gas burner 15. The high-temperature combustion environment of sulfur in the sulfur incinerator 4 achieves the standard treatment of the organic waste gas. Thus, this invention only requires a small addition to existing sulfuric acid production equipment to achieve industrial treatment of organic waste gas, simultaneously treating harmful substances in the organic waste gas and reducing environmental pollution. Furthermore, the heat energy generated during the decomposition of organic matter in the organic waste gas is converted into useful steam, achieving waste heat recovery and improving the overall efficiency of industrial organic waste gas treatment. In addition, this embodiment is applicable to various environments for organic waste gas reuse, expanding its applicability. In summary, this embodiment has the advantages of high comprehensive efficiency and wide applicability.
