Description

Technical Field

[0001] This utility model relates to the field of carbon emission detection technology, and more specifically, to a waste gas combustion system. Background Technology

[0002] Waste gas emissions have always been a significant environmental issue in industrial production. These emissions contain various pollutants, including volatile organic compounds (VOCs), acidic and alkaline gases, fumes from furnaces, and cooking fumes from commercial or residential kitchens. The emission of these pollutants not only disrupts the ecological balance and reduces air quality but also poses a direct threat to human health. Therefore, waste gas must undergo purification treatment to ensure that its emissions meet national and regional environmental standards before being released into the atmosphere, thereby minimizing its adverse impacts on the environment and public health.

[0003] Currently, the main technologies for treating waste gas include activated carbon adsorption, condensation recovery, and catalytic combustion. During catalytic combustion, a large amount of greenhouse gases are inevitably produced, primarily carbon dioxide and nitrous oxide. Greenhouse gas emissions are a major cause of global warming; their accumulation in the atmosphere creates the greenhouse effect, leading to rising Earth's surface temperatures and triggering a series of chain reactions, including more extreme weather events, glacial melting, and rising sea levels. However, existing waste gas treatment equipment has limitations in monitoring carbon emissions, relying mainly on periodic manual testing and estimation, and cannot achieve real-time monitoring and calculation. Utility Model Content

[0004] The main objective of this invention is to provide a waste gas combustion system that can solve the problem that existing waste gas treatment equipment mainly relies on periodic manual testing and estimation of carbon emissions, and cannot achieve real-time monitoring and accounting.

[0005] To achieve the above objectives, this utility model provides an exhaust gas combustion system, comprising: a combustion device having a combustion chamber; an exhaust gas delivery pipeline connected to the combustion chamber; a first combustion-supporting gas delivery pipeline connected to the combustion chamber, wherein a first detection component is provided on the first combustion-supporting gas delivery pipeline, the first detection component including a first flow detection unit and a first gas concentration detection unit; an exhaust pipeline connected to the combustion chamber, wherein a second detection component is provided on the exhaust pipeline, the second detection component including a second flow detection unit and a second gas concentration detection unit; and an accounting system including a carbon emission accounting module, wherein both the first and second detection components are communicatively connected to the carbon emission accounting module.

[0006] Furthermore, a third detection component is installed on the exhaust gas transmission pipeline. The third detection component includes a third flow detection unit and a third gas concentration detection unit, both of which are communicatively connected to the carbon emission accounting module.

[0007] Furthermore, the exhaust gas combustion system also includes a second combustion-supporting gas delivery pipeline, which is connected to the combustion chamber.

[0008] Furthermore, the combustion device is provided with a first air inlet, a second air inlet, and an exhaust port that are connected to the combustion chamber. The first air inlet, the second air inlet, and the exhaust port are located on different side walls of the combustion device. The first combustion gas delivery pipeline and the second combustion gas delivery pipeline are both connected to the second air inlet. The exhaust gas delivery pipeline is connected to the first air inlet, and the exhaust pipeline is connected to the exhaust port.

[0009] Furthermore, the exhaust gas combustion system also includes a filter device, which is installed at the inlet end of the exhaust gas delivery pipeline.

[0010] Furthermore, the exhaust gas combustion system also includes a first air supply device and a second air supply device. The first air supply device is connected to the exhaust gas conveying pipeline, and the second air supply device is connected to the first combustion-supporting gas conveying pipeline.

[0011] Furthermore, the first flow detection unit and the first gas concentration detection unit are arranged sequentially along the direction of waste gas transport, and the second flow detection unit and the second gas concentration detection unit are arranged sequentially along the direction of waste gas transport.

[0012] Furthermore, the exhaust gas combustion system also includes communication equipment, and both the first detection component and the second detection component are connected to the carbon emission accounting module via the communication equipment.

[0013] Furthermore, the exhaust gas combustion system also includes a chimney, with the exhaust pipe's outlet end connected to the chimney.

[0014] Furthermore, the exhaust pipeline includes a main exhaust pipe and multiple exhaust branch pipes. The main exhaust pipe is connected to the combustion chamber. The second detection component is installed on the main exhaust pipe. One end of each of the multiple exhaust branch pipes is connected to the main exhaust pipe, and the other end of each of the multiple exhaust branch pipes is connected to the chimney.

[0015] The present invention comprises a combustion device, an exhaust gas delivery pipeline, a first combustion-supporting gas delivery pipeline, an exhaust pipeline, and a calculation system. Exhaust gas is delivered to the combustion chamber via the exhaust gas delivery pipeline, and the first combustion-supporting gas (such as air) is delivered to the combustion chamber via the first combustion-supporting gas delivery pipeline. Both gases burn within the combustion chamber, and the resulting gases are discharged through the exhaust pipeline. The first combustion-supporting gas delivery pipeline is equipped with a first flow rate detection unit and a first gas concentration detection unit, used to detect the flow rate and concentration of carbon dioxide in the first combustion-supporting gas in real time. The exhaust pipeline is equipped with a second flow rate detection unit and a second gas concentration detection unit, used to detect the amounts of carbon dioxide, methane, and nitrous oxide emitted after combustion, i.e., the carbon emissions generated during the exhaust gas combustion process. Since both the first and second detection components are communicatively connected to the carbon emission calculation module, the detected data is transmitted to the carbon emission calculation module for timely and accurate processing. The carbon emission calculation module can automatically calculate the carbon emissions during the exhaust gas combustion process based on this real-time data, including the emissions of greenhouse gases such as carbon dioxide, nitrous oxide, and methane, thereby achieving real-time carbon emission calculation. Compared to existing technologies that rely on periodic manual testing and estimation, this method can continuously collect and analyze data, detect and calculate carbon emissions in real time, and thus achieve automation and accuracy in carbon emission accounting.

Detailed Implementation

[0021] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, this utility model provides an exhaust gas combustion system, which includes: a combustion device 10 having a combustion chamber; an exhaust gas delivery pipeline 20 communicating with the combustion chamber; a first combustion-supporting gas delivery pipeline 40 communicating with the combustion chamber, the first combustion-supporting gas delivery pipeline 40 being provided with a first detection component 30, the first detection component 30 including a first flow detection unit 31 and a first gas concentration detection unit 32; an exhaust pipeline 50 communicating with the combustion chamber, the exhaust pipeline 50 being provided with a second detection component 60, the second detection component 60 including a second flow detection unit 61 and a second gas concentration detection unit 62; and an accounting system including a carbon emission accounting module, the first detection component 30 and the second detection component 60 being communicatively connected to the carbon emission accounting module.

[0023] In this embodiment, exhaust gas is transported to the combustion chamber through exhaust gas delivery pipeline 20, and a first combustion-supporting gas (such as air) is transported to the combustion chamber through a first combustion-supporting gas delivery pipeline 40. Both gases are burned in the combustion chamber, and the resulting gases are discharged through exhaust pipeline 50. The first combustion-supporting gas delivery pipeline 40 is equipped with a first flow detection unit 31 and a first gas concentration detection unit 32, which are used to detect the flow rate and concentration of carbon dioxide in the first combustion-supporting gas in real time, respectively. The exhaust pipeline 50 is equipped with a second flow detection unit 61 and a second gas concentration detection unit 62, which are used to detect the amounts of carbon dioxide, methane, and nitrous oxide emitted after combustion, i.e., the carbon emissions generated during the exhaust gas combustion process. Since both the first detection component 30 and the second detection component 60 are communicatively connected to the carbon emission calculation module, it ensures that the detected data can be transmitted to the carbon emission calculation module for processing in a timely and accurate manner. The carbon emission calculation module can automatically calculate the carbon emissions during the exhaust gas combustion process based on this real-time data, including the emissions of greenhouse gases such as carbon dioxide, nitrous oxide, and methane, thereby achieving real-time carbon emission calculation. Compared to existing technologies that rely on periodic manual testing and estimation, this method allows for continuous data collection and analysis, real-time detection and calculation of carbon emissions, thereby achieving automation and accuracy in carbon emission accounting. The exhaust gas combustion system of this application has a simple structure and is easy to operate, enabling periodic or continuous monitoring of carbon emissions during the exhaust gas combustion process.

[0024] like Figure 1 As shown, in one embodiment of the present invention, a third detection component is provided on the exhaust gas conveying pipeline 20. The third detection component includes a third flow detection unit and a third gas concentration detection unit, both of which are communicatively connected to the carbon emission accounting module.

[0025] In this embodiment, a third flow detection unit and a third gas concentration detection unit are provided on the waste gas delivery pipeline 20. If the waste gas contains carbon dioxide, the third flow detection unit and the third gas concentration detection unit are used to detect the flow rate and concentration of carbon dioxide in the waste gas, respectively.

[0026] In one embodiment, the first flow detection unit 31, the second flow detection unit 61, and the third flow detection unit are all flow meters.

[0027] In one embodiment, the first gas concentration detection unit 32, the second gas concentration detection unit 62, and the third gas concentration detection unit all employ existing greenhouse gas emission monitoring instruments, the specific structures of which will not be described in detail here.

[0028] like Figure 1 As shown, in one embodiment of the present invention, the exhaust gas combustion system further includes a second combustion-supporting gas delivery pipeline 70, which is connected to the combustion chamber.

[0029] In this embodiment, the second combustion-supporting gas delivery pipeline 70 is used to deliver methane into the combustion chamber. As a high-energy-density fuel, methane has a calorific value much higher than that of air. Introducing methane into the exhaust gas combustion process can significantly increase the combustion temperature, thereby improving combustion efficiency and ensuring that harmful components in the exhaust gas can be more thoroughly oxidized and decomposed, reducing the emission of pollutants from incomplete combustion.

[0030] like Figure 1 As shown, in one embodiment of the present invention, the combustion device 10 is provided with a first air inlet 11, a second air inlet 12 and an exhaust port 13 that are connected to the combustion chamber. The first air inlet 11, the second air inlet 12 and the exhaust port 13 are located on different side walls of the combustion device 10. The first combustion-supporting gas delivery pipeline 40 and the second combustion-supporting gas delivery pipeline 70 are both connected to the second air inlet 12. The exhaust gas delivery pipeline 20 is connected to the first air inlet 11 and the exhaust pipeline 50 is connected to the exhaust port 13.

[0031] In this embodiment, by introducing the first combustion-supporting gas (such as air) and the second combustion-supporting gas (such as methane) into the combustion chamber from different locations, a more uniform gas mixing can be achieved, improving combustion stability and efficiency, and ensuring that harmful components in the exhaust gas are completely burned. Both the first combustion-supporting gas delivery line 40 and the second combustion-supporting gas delivery line 70 are connected to the second air inlet 12, providing flexibility in adjusting combustion conditions. When treating different types of exhaust gas, the system can dynamically adjust the ratio of the two combustion-supporting gases as needed to achieve higher combustion efficiency and lower greenhouse gas emissions.

[0032] like Figure 1As shown, in one embodiment of the present invention, the exhaust gas combustion system further includes a filter device 80, which is disposed at the air inlet end of the exhaust gas conveying pipeline 20.

[0033] In this embodiment, the filter device 80 can effectively remove particulate matter and macromolecular pollutants, such as dust, from the exhaust gas, preventing them from entering the combustion device 10 and affecting combustion efficiency and equipment performance. The filter device 80 can protect the combustion device 10, reduce maintenance frequency, and extend its service life.

[0034] In one embodiment, the filtration device 80 employs a cyclone separator.

[0035] like Figure 1 As shown, in one embodiment of the present invention, the exhaust gas combustion system further includes a first air supply device 90 and a second air supply device 100. The first air supply device 90 is connected to the exhaust gas conveying pipeline 20, and the second air supply device 100 is connected to the first combustion-supporting gas conveying pipeline 40.

[0036] In this embodiment, the first air supply device 90 is used to deliver exhaust gas to the combustion chamber, and the second air supply device 100 is used to deliver the first combustion-supporting gas to the combustion chamber.

[0037] In one embodiment, both the first air supply device 90 and the second air supply device 100 are blowers.

[0038] like Figure 1 As shown, in one embodiment of the present invention, the first flow detection unit 31 and the first gas concentration detection unit 32 are arranged sequentially along the direction of waste gas conveying, and the second flow detection unit 61 and the second gas concentration detection unit 62 are arranged sequentially along the direction of waste gas conveying.

[0039] In this embodiment, this arrangement enables the exhaust gas combustion system to respond quickly to changes in exhaust gas flow and concentration, adjust the combustion strategy in a timely manner, and ensure combustion efficiency under different operating conditions.

[0040] like Figure 1 As shown, in one embodiment of the present invention, the exhaust gas combustion system further includes a communication device, and the first detection component 30 and the second detection component 60 are both connected to the carbon emission accounting module through the communication device.

[0041] In this embodiment, the communication device can realize information transmission and communication. The first detection component 30 and the second detection component 60 are connected to the carbon emission accounting module through the communication device, so that the exhaust gas combustion system can realize real-time data transmission and automated processing, thereby improving the efficiency of system operation.

[0042] In one embodiment, the communication device is a switch or a router.

[0043] like Figure 1 As shown, in one embodiment of the present invention, the exhaust gas combustion system further includes a chimney 200, and the exhaust pipe 50 is connected to the chimney 200 at its outlet end.

[0044] The above-mentioned design ensures that the exhaust gases after combustion can be smoothly and quickly discharged into the atmosphere, avoiding their retention within the system and reducing the possibility of secondary pollution. Furthermore, the exhaust gases are emitted into the air through chimney 200, significantly reducing their impact on the ground environment.

[0045] like Figure 1 As shown, in one embodiment of the present invention, the exhaust pipeline 50 includes an exhaust main pipe and a plurality of exhaust branch pipes. The exhaust main pipe is connected to the combustion chamber. The second detection component 60 is installed on the exhaust main pipe. One end of each of the plurality of exhaust branch pipes is connected to the exhaust main pipe, and the other end of each of the plurality of exhaust branch pipes is connected to the chimney 200.

[0046] The above settings ensure that the exhaust gas after combustion can be evenly distributed into the chimney 200, avoiding uneven exhaust gas emission caused by a single outlet, thus ensuring more uniform diffusion of exhaust gas in the atmosphere.

[0047] In one embodiment, the exhaust gas combustion detection system further includes a data acquisition module. The data acquisition module is connected to the carbon emission calculation module via a communication device. The data acquisition module collects the power consumption of the exhaust gas combustion device 10 and transmits the relevant data to the carbon emission calculation module via the communication device. The carbon emission calculation module includes carbon emission calculation software. The carbon emission calculation software receives data from the first flow detection unit 31, the first gas concentration detection unit 32, the second flow detection unit 61, the second gas concentration detection unit 62, and the data acquisition module, including exhaust gas flow rate, exhaust gas concentration, and the device's power consumption. Then, using preset calculation formulas and algorithms, it calculates the greenhouse gas (such as carbon dioxide, methane, and nitrous oxide) emissions during the exhaust gas combustion process based on the received data.

[0048] Specifically, carbon emission accounting for waste gas combustion systems needs to consider not only the carbon emissions generated during the combustion process but also the carbon emissions from the electrical energy consumption of the waste gas combustion treatment equipment (e.g., fans, igniters, etc.). The formula for calculating carbon dioxide emissions from electricity consumption is as follows: Carbon emissions from electricity consumption = Electricity consumption × Electricity emission factor, where the electricity emission factor is the average carbon dioxide emission factor published by the relevant national authority. The formula for calculating the total carbon emissions from waste gas combustion is as follows: Total carbon emissions = Carbon emissions from waste gas combustion + Carbon emissions from electricity consumption. The amount of greenhouse gases produced by waste gas combustion can be calculated using the following formula: Greenhouse gas quantity = Waste gas flow rate × Greenhouse gas concentration. The corresponding carbon emissions from greenhouse gases can be calculated using the following formula: Carbon emissions from waste gas combustion = Greenhouse gas quantity × Global warming potential of greenhouse gases, where the global warming potential of greenhouse gases can be obtained from IPCC reports. The 100-year global warming potential of methane is 25, and the 100-year global warming potential of nitrous oxide is 298. Waste gas combustion treatment can be divided into waste gas combustion emissions under normal operating conditions and waste gas combustion emissions under abnormal operating conditions caused by accidents, start-up and shutdown, equipment maintenance, etc. Greenhouse gas emissions generated by waste gas combustion under normal operating conditions include carbon dioxide and nitrous oxide, while greenhouse gas emissions generated by waste gas combustion under abnormal operating conditions include carbon dioxide, nitrous oxide, and unburned methane. If some of the carbon dioxide contained in the waste gas before treatment is generated by the process, this part of the carbon dioxide is included in the carbon emission accounting of the process. Furthermore, the exhaust gas contains not only pollutants generated by the emission source but also components in the air. Therefore, when calculating the carbon emissions generated by the exhaust gas combustion activity, the carbon dioxide already present in the air needs to be subtracted. Carbon dioxide emissions = outlet exhaust gas flow rate × outlet carbon dioxide concentration - inlet exhaust gas flow rate × inlet carbon dioxide concentration. Nitrous oxide emissions = outlet exhaust gas flow rate × outlet nitrous oxide concentration. Methane emissions = outlet exhaust gas flow rate × outlet methane concentration. Exhaust gas combustion carbon emissions = carbon dioxide emissions + nitrous oxide emissions + methane emissions. The inlet exhaust gas flow rate can be obtained by the first flow detection unit 31, and the inlet carbon dioxide concentration can be obtained by the first gas concentration detection unit 32. The outlet exhaust gas flow rate can be obtained by the second flow detection unit 61, and the outlet carbon dioxide concentration can be obtained by the second gas concentration detection unit 62.

[0049] In one embodiment, the carbon emission accounting module can provide computing power and run software applications in a network environment to calculate carbon emission data of the exhaust gas combustion system based on data from the first detection component 30 and the second detection component 60, and store the relevant carbon emission data.

[0050] In one embodiment, the exhaust gas combustion detection system further includes a network printer and a web interface. Both the network printer and the web interface are communicatively connected to the carbon emission accounting module. The carbon emission data of the selected exhaust gas combustion device can be printed through the network printer, and the carbon emission data of the exhaust gas combustion device can be viewed remotely through the web interface.

[0051] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: a combustion device, an exhaust gas conveying pipeline, a first combustion-supporting gas conveying pipeline, an exhaust pipeline, and a calculation system are provided. The exhaust gas is conveyed to the combustion chamber through the exhaust gas conveying pipeline, and the first combustion-supporting gas (such as air) is conveyed to the combustion chamber through the first combustion-supporting gas conveying pipeline. The two are burned in the combustion chamber, and the gas after combustion is discharged through the exhaust pipeline. The first combustion-supporting gas delivery pipeline is equipped with a first flow detection unit and a first gas concentration detection unit, which are used to detect the flow rate and concentration of carbon dioxide in the first combustion-supporting gas in real time, respectively. The exhaust pipeline is equipped with a second flow detection unit and a second gas concentration detection unit, which are used to detect the amounts of carbon dioxide, methane, and nitrous oxide emitted after combustion, i.e., the carbon emissions generated during the exhaust gas combustion process. Since both the first and second detection components are communicatively connected to the carbon emission calculation module, it ensures that the detected data can be transmitted to the carbon emission calculation module for processing in a timely and accurate manner. Based on this real-time data, the carbon emission calculation module can automatically calculate the carbon emissions during the exhaust gas combustion process, including the emissions of greenhouse gases such as carbon dioxide, nitrous oxide, and methane, thereby achieving real-time carbon emission calculation. Compared to existing technologies that rely on periodic manual detection and estimation, this method allows for continuous data collection and analysis, real-time detection and calculation of carbon emissions, and thus automates and improves the accuracy of carbon emission calculation.
