[0002] The increasingly serious pollution of industrial waste gas such as haze, ozone and VOCs has aroused widespread social concern. The biggest difference from the control measures of water pollution process is that the whole chain management of water resources, water utilization, water pollution control and wastewater discharge is conducive to the management and quality improvement of water ecological environment. However, the management process of air utilization, total amount and concentration of pollutants in waste gas is difficult to improve.

[0003] In the existing technology, only some indirectly related combustion processes are involved. Industrial waste gas generally only considers relevant process parameters and standard regulations to determine the required air consumption. For example, there are many types of kilns. Taking natural gas combustion to produce heat as an example, if the kiln is a high-temperature temperature control process, taking titanium dioxide calcination as an example, the calcination process is actually a high-temperature reactor process.

The volume concentration of the residual oxygen content in the waste gas is about 15%. According to the general kiln waste gas emission requirements, the waste gas oxygen content ranges from 6-11%, which means that the pollutant emission concentration of the type kiln may exceed the standard.

[0040] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0042] like Figure 1As shown, the present invention provides an industrial waste gas recycling treatment method, the industrial waste gas recycling treatment method comprising:

[0043] In step S11, the original industrial waste gas is discharged into the gas utilization device through the circulation blower, and after the original industrial waste gas is utilized, the remaining industrial waste gas is discharged into the waste gas treatment device;

[0044] In step S12, the remaining industrial waste gas is purified by the waste gas treatment device, and the purified industrial waste gas is discharged into at least one waste gas standard treatment device;

[0045] In step S13, after being processed by the at least one waste gas standard treatment device, the induced draft fan device discharges the industrial waste gas that has met the standards into a preset chimney, and the industrial waste gas that does not meet the standards is circulated and transported to the gas utilization device.

[0046] In one embodiment, industrial waste gas first enters the gas utilization device through a circulating blower to utilize resources or recover energy from the waste gas. The remaining waste gas enters the waste gas treatment device for purification. The purified waste gas enters at least one waste gas standard treatment device to ensure that the emission meets the standard. The waste gas that meets the standard is discharged into a preset chimney through an induced draft fan device; the waste gas that does not meet the standard is recirculated back to the gas utilization device. Flow meters are set in each key pipeline to monitor the flow of waste gas at different stages. The gas flow rate Q1 indicates the flow rate of waste gas that does not meet the standard being circulated back to the gas utilization device. The gas flow rate Q2 indicates the flow rate of waste gas entering the induced draft fan device. The gas flow rate Q3 indicates the flow rate of waste gas that meets the standard discharged by the induced draft fan into the chimney. Compare Q2 with the sum of Q1 and Q3 in real time to ensure the consistency of gas flow and the stability of closed-loop control. If the flow rates are not equal, it means that there is a problem with the pipeline or device. When the gas flow monitoring determines that Q2 is not equal to the sum of Q1 and Q3, the specific flow data of each pipeline can be used to analyze which link has a problem. Fault diagnosis provides a clear method to locate the fault point by troubleshooting flow anomalies. A pressure gauge and a safety valve are set at the induced draft fan device to monitor the pressure of the exhaust gas. When the pressure gauge detects that the pressure value reaches the preset warning value, the safety valve is closed to prevent excessive pressure from causing a safety accident. Safety is protected based on pressure monitoring to prevent equipment damage or exhaust gas leakage. The dual monitoring of gas flow and pressure, as well as the cyclic treatment of exhaust gas that does not meet the standards, form a closed-loop control to ensure the stability and safety of the system, and can continuously adjust the exhaust gas treatment process and automatically provide feedback and adjustments in abnormal situations.

[0047] In the process of waste gas treatment, an intelligent control system is added, and the Internet of Things (IoT) technology is combined to collect and analyze waste gas flow, pressure, temperature and other parameters in real time. Through big data analysis technology, historical data and real-time data are compared to find potential abnormal conditions or predict equipment maintenance needs, realize predictive maintenance, and avoid sudden failures. According to the composition of the waste gas, the waste gas can be divided into different categories of gas, and graded and purified through multi-level classification treatment devices. For example, for waste gas with a higher calorific value, energy recovery can be carried out first; for waste gas with a high concentration of pollutants, deep purification treatment is given priority. This can maximize the efficiency and resource utilization of waste gas treatment. In addition to gas utilization devices, other waste gas resource technologies can be expanded, such as extracting specific components in the waste gas (such as carbon dioxide and carbon monoxide), combining chemical reactions or microbial treatment, and converting them into usable chemicals or energy, further improving the resource utilization rate of waste gas. Based on real-time monitoring data, the operating status of each device can be automatically adjusted, such as the speed of the blower and induced draft fan, the operating load of the waste gas treatment device, etc., to ensure the maximum efficiency and effect of waste gas treatment. At the same time, if a problem occurs in a certain section of the pipeline or equipment, the faulty link can be automatically isolated and the processing flow can be reorganized to maintain the normal operation of the system.

[0048] The technical solution in this embodiment recycles the original industrial waste gas through a gas utilization device to reduce energy waste, and performs multi-stage purification through a waste gas treatment device and a standard treatment device to ensure that the final discharged waste gas meets environmental protection standards. The waste gas that does not meet the standards is recycled back into the system for further treatment, forming a closed-loop control, effectively reducing pollutant emissions, which not only improves resource utilization but also reduces environmental pollution risks.

[0049] In one embodiment, Figure 2 As shown, the following steps S21-S22 are also included:

[0050] In step S21, according to the gas type of the industrial waste gas, the waste gas is discharged to the corresponding waste gas standard treatment device;

[0051] In step S22, the corresponding waste gas treatment device is selected for discharge according to the concentration of harmful gases in the industrial waste gas.

[0052] In one embodiment, based on the gas type of the industrial waste gas, a treatment device suitable for treating the type of waste gas is selected. Different types of industrial waste gas may contain different pollutant components (such as acidic gas, alkaline gas, volatile organic compounds, etc.), and each gas type requires a specific treatment device or process to efficiently remove pollutants. The determination of the gas type is the first step in determining the treatment method, which ensures that the device into which the waste gas enters can effectively treat a specific type of pollutant component. According to the concentration of harmful gases in the waste gas, an appropriate treatment device is selected. Even for the same type of gas, different concentrations will affect the selection of the treatment device. Waste gas with a higher concentration of harmful gases requires a more stringent or advanced treatment device to ensure that the purification effect meets the standard, while waste gas with a lower concentration may only need to pass through an ordinary treatment device. By judging the gas concentration, it is ensured that the waste gas is properly purified and the emissions meet environmental protection standards.

[0053] Based on the judgment of gas type, it is ensured that the waste gas enters the most suitable preliminary treatment device. Different types of gas treatment devices may use different technical means, such as chemical absorption, catalytic oxidation, or physical filtration. Therefore, diverting the waste gas to the corresponding treatment equipment according to the type is the basis of the entire treatment process. After the gas type is determined, the judgment of concentration plays a role in further refining and optimizing the treatment. In the same type of gas, different concentrations correspond to different treatment requirements. For example, for high-concentration waste gas, it may be necessary to increase the reaction time of the treatment, improve the treatment efficiency of the device, or adopt multi-stage treatment. Concentration judgment ensures the depth and thoroughness of the treatment, which is a supplement and refinement of the gas type judgment. When each waste gas enters the treatment device, it will be comprehensively considered based on its gas type and concentration. This parallel selection logic can ensure that waste gas with different characteristics gets the most appropriate treatment plan, thereby improving the treatment efficiency and effect. The two criteria of gas type and concentration work together to ensure that each type of waste gas not only enters the appropriate treatment device, but also can be targeted and purified according to its specific degree of pollution. Gas type selection is the first step in determining the treatment path, and concentration further optimizes the intensity and method of treatment. This complementarity ensures that the exhaust gas meets both the type requirements and the concentration requirements of the environmental protection standards. Based on the choice of gas type or concentration, the exhaust gas is ensured to comply with environmental protection regulations. The exhaust gas treatment system can ensure the full removal of pollutants so that the exhaust gas reaches the safety level required by regulations.

[0054] In addition to the type of gas and the concentration of harmful gases, the treatment of waste gas can also be refined according to other parameters such as temperature, humidity, pressure, and concentration of volatile organic compounds (VOCs). For example, high-temperature waste gas may need to be cooled first; high-humidity waste gas may need to be pre-dehumidified to improve the efficiency of subsequent purification devices. Adding judgments on these parameters can more accurately match the treatment device, making the entire system more flexible and efficient. By real-time monitoring of the multi-dimensional parameters of the gas and combining intelligent algorithms, the system can automatically adjust the operating mode of the treatment device. For example, a certain type of gas needs to increase the amount of catalyst when the concentration is high, and the reaction temperature needs to be increased at low temperatures. Exhaust gas treatment is divided into multiple levels to cope with different types and concentrations of waste gas. Primary treatment can be used for low-concentration waste gas or gas containing a small amount of pollutants, using relatively simple devices such as physical filtration or adsorption devices; intermediate treatment is suitable for waste gas with higher concentration or complex pollutant components, using chemical absorption, catalytic oxidation and other technologies; deep treatment is specifically for high-concentration waste gas containing highly toxic or difficult-to-treat components, using multi-stage purification or special high-efficiency treatment devices. This layered processing logic can provide the most appropriate treatment solution based on the different characteristics of the exhaust gas, saving energy while ensuring the treatment effect.

[0055] At each stage of waste gas treatment, energy recovery devices such as heat recovery devices and waste heat power generation devices can be set up. In particular, for high-temperature waste gas or energy-rich waste gas, heat or other forms of energy can be recovered during the treatment process to achieve secondary utilization of resources, thereby further improving the overall benefits of the system. By introducing artificial intelligence (AI) algorithms, the system can automatically optimize the waste gas treatment path and device configuration according to changes in waste gas type, concentration, and other real-time parameters. For example, AI can predict the emission pattern of a certain type of waste gas based on historical data, and adjust the status of the treatment equipment in advance to ensure that the equipment always operates within the high-efficiency range. AI can also automatically select the best treatment solution by learning the system's treatment effect, reducing the time cost of manual intervention and equipment adjustment.

[0056] When the exhaust gas parameters change, the system can automatically switch the exhaust gas treatment device or adjust the flow distribution. For example, when the exhaust gas concentration in a certain section suddenly increases, the system can automatically switch to the advanced treatment device and adjust the operating status of other devices as needed to ensure the smooth operation of the system. This automated diversion and switching logic can significantly improve the system's ability to cope with complex exhaust gases. The treatment device can automatically adjust the load according to the real-time exhaust gas flow and pollutant concentration. For example, when the gas flow is large and the pollutant concentration is high, the device's processing capacity and operating speed will automatically increase; when the exhaust gas flow and concentration decrease, the system will reduce the load and reduce energy consumption. This dynamic load management can optimize the system's operating efficiency, reduce energy consumption, and extend the service life of the equipment. In order to cope with sudden large-scale exhaust gas emissions or equipment failures, redundant treatment equipment can be set up. When a device is overloaded or needs maintenance, the redundant equipment will automatically be put into operation to ensure the continuous operation of exhaust gas treatment. At the same time, the system can automatically distribute the load according to the changes in the exhaust gas flow, so that the operating load of each treatment device is balanced and the excessive use of a single device is avoided. Further develop the useful components in the exhaust gas and convert them into by-products or energy through chemical reactions or physical separation. For example, some industrial waste gas may contain carbon dioxide, carbon monoxide, hydrogen and other components, which can be converted into valuable chemicals such as methanol and synthesis gas through chemical reactions, thus realizing the resource utilization of waste gas. This not only reduces waste gas emissions, but also creates additional economic benefits for enterprises.
