Description

Technical Field

[0001] The present invention belongs to the technical field of energy utilization, and in particular relates to a new type of clean and energy-saving energy utilization and environmental management system. Background Art

[0002] In the current field of environmental governance and new energy, sewage treatment systems, waste incineration systems and electrolytic hydrogen production systems are important components for achieving sustainable urban development. Although there are existing technologies that attempt to combine these three systems, the current combination method mainly focuses on reusing the waste and exhaust gas generated by each system and then using them in other systems, and has not formed a systematic closed-loop energy utilization and environmental governance system.

[0003] In the existing technology, Chinese patent CN117181794A records a system for hydrogen production from urban renewable resources. Although the system includes subsystems such as sewage treatment system, garbage incineration treatment system and electrolytic hydrogen production system, its main function is to integrate various urban renewable resources for hydrogen production, rather than closely combining various systems to form a systematic closed-loop energy utilization and environmental governance system. This situation has led to several obvious deficiencies:

[0004] First, the operational stability of waste incineration power plants is limited by the instability of the calorific value of waste. Due to the large fluctuations in the amount and type of waste, the calorific value of the waste also changes, resulting in unstable power generation efficiency. In order to maintain stable power generation, it is usually necessary to add fossil fuels such as coal or natural gas during the incineration process to increase the calorific value. This not only increases the consumption of fossil resources and easily produces waste gas and other environmental pollution, but also increases the operating cost of the system, weakening the economic and environmental benefits of the power plant.

[0005] Secondly, in terms of sewage treatment, especially for sewage treatment plants in northern regions, under low temperature conditions in winter, it is difficult for the water temperature of the sewage biochemical system to maintain the most suitable temperature range of 30℃ to 35℃. This low temperature environment will significantly affect the effect of sewage treatment and reduce the overall efficiency and treatment capacity of the system.

[0006] These deficiencies show that the combination of existing technologies is limited to the initial integration and partial utilization of resources, and has not achieved a true closed-loop resource and energy cycle. Therefore, it is urgent to develop a technical solution that can effectively integrate the subsystems and form a closed-loop structure to improve energy utilization efficiency and environmental governance, and achieve a comprehensive improvement in the economic and environmental benefits of the system.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention discloses a new type of clean and energy-saving energy utilization and environmental governance system. By integrating sewage treatment, garbage incineration treatment and electrolytic hydrogen production system, it realizes efficient recovery and utilization of energy, recycling of resources and effective reduction of pollutants, significantly reducing carbon emissions and environmental load; the system has the characteristics of self-sufficiency in electricity, low operating cost, intelligent control and efficient operation, and has good flexibility and scalability, and can adapt to a variety of application scenarios, providing strong technical support for achieving sustainable development with high efficiency, energy saving and environmental protection. Through the waste heat boiler in the process of garbage incineration treatment, the heat energy generated by incineration is recovered and used in multiple aspects, including driving steam turbine generators to generate electricity, improving the efficiency of sewage biochemical treatment and providing the required heat for electrolytic hydrogen production. This multiple utilization method significantly improves the utilization rate of energy, reduces energy waste, and achieves the purpose of energy saving.

The present invention significantly improves the utilization efficiency of energy and resources, reduces environmental pollution, reduces the system operation cost, achieves the goals of high efficiency, cleanliness, energy saving and environmental protection, and provides strong technical support for achieving sustainable development.

[0021] 2. The present invention realizes the recycling of resources through the hydrogen and oxygen generated by the electrolytic hydrogen production system. Hydrogen is used to increase the calorific value of waste incineration, and oxygen is used for incineration efficiency enhancement and sewage aeration, which improves the efficiency of incineration and sewage treatment and reduces the emission of harmful substances. At the same time, the recovery and recycling of condensed water reduces the consumption of fresh water and optimizes the management of water resources. The sludge after sludge composting is used as an auxiliary fuel for incineration, which improves the utilization rate of resources and reduces the pollution to the environment caused by direct discharge of sludge. Through efficient resource and energy utilization, the present invention greatly reduces the carbon emissions of the system. For example, the hydrogen of the electrolytic hydrogen production system replaces part of the traditional fossil fuels and reduces the emission of greenhouse gases. The heat generated in the waste incineration process is not only used for power generation, but also for supporting the heat demand in the sewage treatment process, reducing additional energy consumption and carbon dioxide emissions. The system reduces the pollution load of the atmosphere and water bodies and improves the environmental quality through efficient pollution control technology.

[0022] 3. The highly integrated design of the present invention enables each subsystem to support each other and form a self-sufficient closed-loop system. The self-sufficiency of electricity not only reduces the dependence on external power supply, but also reduces the operating cost of the system. The heat energy and by-products (such as hydrogen and oxygen) generated by waste incineration and electrolysis of hydrogen are directly utilized, reducing the need for purchased energy and resources, and further reducing the overall operating cost of the system.

[0023] 4. The present invention integrates multiple control modules to achieve intelligent operation management. Through automated control and real-time monitoring, each system can accurately adjust the operating parameters and optimize the efficiency of each processing link. For example, by accurately regulating the waste heat, the power generation efficiency of the steam turbine generator and the effect of sewage treatment can be maximized. The electrolytic hydrogen production system dynamically adjusts the production of hydrogen and oxygen according to the power supply and demand, which improves the response speed and operation efficiency of the system.

[0024] 5. The present invention uses a variety of advanced environmental governance technologies, and achieves comprehensive governance of solid waste, wastewater and waste gas through efficient sewage treatment, garbage incineration and electrolytic hydrogen production. Through the linkage of multiple systems, the system can effectively remove harmful substances such as organic pollutants and heavy metals in sewage, while reducing the emission of harmful gases during the incineration process, achieving a comprehensive improvement in environmental governance effects.

[0025] 6. The new clean and energy-saving energy utilization and environmental management system in the present invention can be flexibly adjusted and expanded according to actual needs. For example, the electrolysis hydrogen production system can be combined with other renewable energy sources (such as solar energy and wind energy) to further increase the green energy ratio of the system. Each module of the system can be independently upgraded or adjusted according to needs, with good flexibility and scalability, and can adapt to application needs in different scenarios.

[0040] The embodiment of the present invention provides a new clean and energy-saving energy utilization and environmental management system, referring to Figure 1As shown, the novel clean and energy-saving energy utilization and environmental governance system at least comprises a sewage treatment system (1), a garbage incineration treatment system (13) and an electrolytic hydrogen production system (6) which are interconnected; the sewage treatment system (1) comprises a sewage biochemical system, a sewage deep treatment system (2) and a sludge composting bin (11); the sewage biochemical system and the sewage deep treatment system (2) are connected via a first water delivery pipeline (101); water treated by the sewage biochemical system enters the sewage deep treatment system (2) via the first water delivery pipeline (101) for deep treatment; the sewage biochemical system and the sludge composting bin (11) are connected via a first sludge delivery pipeline (201); sludge treated by the sewage biochemical system is transported to the sludge composting bin (11) via the first sludge delivery pipeline (201); A fertilizer bin (11); a garbage incineration treatment system (13) comprising a garbage incinerator (13) and a waste heat boiler (14) connected via a flue gas transmission pipeline (601); an electrolytic hydrogen production system (6) comprising an electrolytic hydrogen production device (6) for generating hydrogen and oxygen, wherein the hydrogen is supplied to the garbage incinerator (13) via a first hydrogen transmission pipeline (401) to increase its calorific value, and the oxygen is transported to the garbage incinerator (13) via a first oxygen transmission pipeline (301) to improve the incineration efficiency, and is connected to the sewage biochemical system via a second oxygen transmission pipeline (302) for aeration; the waste heat boiler (14) is connected to the sewage biochemical system via a first high-temperature steam gas transmission and return pipeline (501), and the steam generated by the waste heat boiler (14) is used to improve the treatment efficiency of the sewage biochemical system.

[0041] The present invention realizes efficient coordination of sewage treatment, garbage incineration and electrolytic hydrogen production by mutual integration. The sewage treatment system (1) performs biochemical and deep treatment on domestic sewage and industrial wastewater to realize the recycling of water resources. The garbage incineration treatment system (13) generates heat energy by incinerating garbage, and the waste heat boiler (14) further uses the heat generated by incineration to generate steam. The steam is not only used for power generation, but also can heat the sewage biochemical system to improve its treatment efficiency. At the same time, the sludge after the sewage biochemical treatment is sent to the sludge composting bin (11) through the first sludge pipeline (201), and after composting and digestion, it is sent to the garbage incinerator (13) through the second sludge pipeline (202) for incineration treatment. It can be used as organic fuel to effectively improve the calorific value of garbage in the garbage incinerator (13). The electrolytic hydrogen production system (6) uses the steam generated by the waste heat boiler (14) and the electricity provided by the power generation system to prepare hydrogen and oxygen by electrolyzing water. The generated hydrogen is used to increase the calorific value of the waste incinerator (13), and the oxygen is used for combustion support during the incineration process and aeration of the sewage biochemical system, thereby improving the energy utilization efficiency and environmental governance effect of the overall system. By integrating sewage treatment, waste incineration treatment and electrolytic hydrogen production systems, the recycling of multiple energy sources and resources is achieved, significantly improving the energy efficiency of the overall system. The use of hydrogen and oxygen further improves the calorific value and incineration efficiency of the incinerator (13), while reducing the use of fossil fuels and carbon dioxide emissions. The comprehensive utilization of waste heat is not only used for power generation, but also optimizes sewage treatment efficiency. The overall system design is compact, which helps to reduce energy consumption and operating costs, improve environmental friendliness, and achieve the goal of energy conservation and emission reduction.

[0042] In some embodiments, the sewage treatment system (1) further comprises a sewage raw water system and a sewage pretreatment system before the sewage biochemical system is treated, such as Figure 1 As shown, the sewage is firstly homogenized and mixed through the sewage raw water system, and then the pH value of the sewage is adjusted through the sewage pretreatment system, and after preliminary physical sedimentation or chemical sedimentation, it enters the sewage biochemical system for organic matter hydrolysis and acidification and aerobic decomposition, nitrification, denitrification, and phosphorus removal; the water after biochemical treatment enters the sewage deep treatment system (2) through the first water pipeline (101) for deep treatment, and deep treatment including but not limited to advanced oxidation or membrane separation treatment. Part of the water after deep treatment is reused by the municipal government to improve the utilization rate of water resources; the other part enters the pure water purification system (3) through the fourth water pipeline (104), and is further purified by using water purification technologies including but not limited to reverse osmosis membrane, EDI, etc.

[0043] In some embodiments, when sewage enters the sewage biochemical system for treatment, various fans with blowing function including but not limited to centrifugal fans, Roots fans, magnetic levitation fans, etc. are used for blowing.

[0044] In some embodiments, the waste incineration treatment system (13) further includes a waste pretreatment system, and the waste is sorted and dried by the waste pretreatment system before being sent to the waste incinerator (13). The high-temperature flue gas generated by the waste incinerator (13) is sent to the waste heat boiler (14) through the flue gas conveying pipeline (601), and the high-temperature flue gas is discharged after being desulfurized and denitrified by the flue gas treatment system to prevent environmental pollution.

[0045] In some embodiments, the waste heat boiler (14) is connected to the sewage biochemical system through the first high-temperature steam gas transmission and return pipeline (501), and the first high-temperature steam gas transmission and return pipeline (501) is used as a heating pipeline to provide heat for the sewage biochemical system, ensuring that when the external environment temperature is too low and the inlet water temperature is too low, the water temperature in the sewage biochemical system is maintained at 30°C to 35°C, that is, the most suitable biological treatment temperature. The first high-temperature steam gas transmission and return pipeline (501) is provided with a process valve interlocked with the biochemical system water temperature control to adjust the high-temperature steam transmission flow rate.

[0046] Furthermore, the new clean and energy-saving energy utilization and environmental management system also includes a steam turbine generator (15), which is connected to the waste heat boiler (14) through the first high-temperature steam gas pipeline (504), and the steam generated by the waste heat boiler (14) drives the steam turbine generator (15) to generate electricity. The output of the steam turbine generator (15) supplies the mains electricity through the first circuit (701), and the steam turbine generator (15) is connected to the electrolytic hydrogen production system (6) through the second circuit (702) to provide electricity for the electrolytic hydrogen production system (6). The waste heat boiler (14) in the garbage incineration treatment system (13) converts the heat generated by the incineration into steam, and the steam is transported to the steam turbine generator (15) through the first high-temperature steam gas pipeline (504), driving it to operate and generate electricity. A part of the generated electric energy is supplied to the mains network through the first circuit (701), and another part of the electric energy is distributed to the electrolytic hydrogen production system (6) for electrolyzing water to produce hydrogen and oxygen. Although most of the electricity used by the electrolytic hydrogen production system (6) is currently derived from renewable energy, renewable energy sources such as wind power and photovoltaic power generation systems all have power generation peak and valley problems, which requires the configuration of an energy storage system to maintain the stability of the input power of the hydrogen production system. Therefore, the present invention not only improves the utilization rate of incineration heat energy through this energy conversion and reuse method, but also provides a stable source of electricity for electrolytic hydrogen production through waste heat power generation, forming a system of energy complementation and recycling, without the need for additional energy storage systems, thereby reducing capital investment and saving costs. The present invention achieves effective utilization of waste heat from garbage incineration by introducing a steam turbine generator (15) and increases the energy output of the system. During the power generation process, the system efficiently converts the waste heat generated by incineration into electricity, and directly supplies it to the city power and the electrolytic hydrogen production system (6), reducing dependence on external power grid electricity and further improving energy self-sufficiency. At the same time, waste heat power generation can not only provide power support for hydrogen production, but also provide electricity for the city power, reducing the burden on the traditional power system and improving the overall energy conservation and emission reduction effect. The present invention can effectively balance the peak and valley problems of renewable energy electrolysis hydrogen production system (6) due to wind power, photovoltaic and other renewable energy power generation systems by coupling the power supply line of waste incineration power generation as a stable backup power source. No additional energy storage system is required, thereby reducing capital investment and saving costs. It ensures that the electrolysis hydrogen production system (6) can be used as backup power to ensure the stable operation of the electrolysis hydrogen production process when wind, light and other renewable energy power generation is insufficient.

[0047] In some embodiments, the steam turbine generator (15) can select different models and specifications according to different process requirements and steam parameters, such as using a back pressure steam turbine or a condensing steam turbine to optimize the efficiency of cogeneration. The design of the steam transmission pipeline can adopt multi-stage heating or supercritical steam technology to further improve the utilization efficiency of steam. For the electrolysis hydrogen production system (6), the power supply method can be adjusted according to demand, such as introducing energy storage devices and combining renewable energy generation, using the peak and valley electricity price differences for power scheduling, so as to achieve the optimization of the electrolysis process.

[0048] Furthermore, the novel clean and energy-saving energy utilization and environmental management system also includes a condensed water storage system (12), and the water condensed by the steam turbine generator (15) is connected to the condensed water storage system (12) through the second water pipeline (102), and the condensed water storage system (12) is connected to the waste heat boiler (14) through the third water pipeline (103) to recycle the condensed water. The condensed water generated by the steam turbine generator (15) during operation is transported to the condensed water storage system (12) through the second water pipeline (102) for centralized storage and management. Subsequently, the recovered condensed water is transported back to the waste heat boiler (14) through the third water pipeline (103) for recycling. This process not only reduces the waste of water resources, but also effectively reduces the system's dependence on external water sources, further optimizing the recycling efficiency of water resources. The present invention recycles and reuses the condensed water generated by the operation of the steam turbine generator (15), thereby significantly improving the water resource utilization efficiency of the system and reducing the consumption of industrial water. The recycling and reuse of condensed water reduces the demand for water replenishment of the waste heat boiler (14) and reduces the use of external fresh water sources, which has the dual effects of saving water resources and protecting the environment. In addition, the recycling of water can also reduce the operating cost of the system and further improve the economy and sustainability of the system.

[0049] In some embodiments, the design of the condensate storage system (12) can adopt different storage and treatment schemes according to the change of the condensate amount. For example, a condensate purification treatment device can be introduced to further improve the quality of the recovered water to meet different process requirements. In addition, the condensate storage system (12) can also be integrated with other systems, such as connecting to an industrial cooling system to fully utilize the potential cooling benefits of condensate. For water pipelines, corrosion-resistant materials are selected or the use of water treatment chemicals is increased to ensure the quality of the condensate and the long-term stable operation of the pipeline. The configuration of the entire system can also be flexibly adjusted according to site conditions, such as adding pump stations or control valves to accurately control the flow direction and usage efficiency of water.

[0050] Furthermore, the electrolytic hydrogen production system (6) includes a pure water purification system (3), a pure water heat exchanger (4), and a pure water storage tank (5) connected in sequence; the pure water purification system (3) is connected to the sewage deep treatment system (2) through the fourth water pipeline (104), and the pure water purified by the pure water purification system (3) enters the pure water heat exchanger (4) through the fifth water pipeline (105), and the pure water after heat exchange enters the pure water storage tank (5) through the sixth water pipeline (106). In the present invention, the water provided by the sewage deep treatment system (2) enters the pure water purification system (3) through the fourth water pipeline (104) for purification, removes impurities and pollutants in the water, and produces high-purity water. The purified pure water is transported to the pure water heat exchanger (4), and through heat exchange with the waste heat in the system, the water temperature is increased to adapt to the optimal working conditions of electrolytic hydrogen production. The pure water after heat exchange then enters the pure water storage tank (5) through the sixth water pipeline (106) for storage and serves as the water source for the electrolytic hydrogen production device (6). The entire process ensures the efficient operation of the electrolytic hydrogen production process through efficient water resource recycling and thermal energy utilization. The present invention optimizes the water quality and water temperature of the electrolytic hydrogen production system (6) by combining the pure water purification system (3) and the heat exchange system, thereby improving the working efficiency and hydrogen output rate of the electrolytic hydrogen production device (6). The water after deep sewage treatment is fully purified and recycled, which effectively reduces the consumption of fresh water resources and improves the environmental protection and sustainability of the system. The heat exchange process uses the system waste heat to preheat the pure water, further saving the energy consumption of electrolytic hydrogen production and significantly reducing the overall operating cost and energy consumption.

[0051] In some embodiments, the pure water purification system (3) can adopt different water treatment technologies, such as reverse osmosis, ion exchange or nanofiltration, and flexibly adjust the purification scheme according to different sewage water quality and treatment requirements. The pure water heat exchanger (4) can adopt various forms such as plate heat exchanger, shell and tube heat exchanger, etc. according to the different heat source temperature and flow rate to achieve the best heat exchange efficiency. For the pure water storage tank (5), its material and design can be adjusted according to system requirements, for example, stainless steel or polymer materials can be selected to improve corrosion resistance and water quality retention performance. In addition, the water inlet parameters of the electrolytic hydrogen production device (6) can be optimized by adjusting the heat exchange capacity of the heat exchanger (4) and the flow setting of the control system to further improve the overall performance of the system.

[0052] Furthermore, the water in the pure water storage tank (5) is divided into two parts, one part is connected to the electrolytic hydrogen production device (6) through the seventh water pipeline (107) to provide water resources for the electrolytic hydrogen production device (6), and the other part is connected to the condensed water storage system (12) through the eighth water pipeline (108). The water stored in the pure water storage tank (5) is distributed into two parts. One part is directly supplied to the electrolytic hydrogen production device (6) through the seventh water pipeline (107) as the water source for electrolytic hydrogen production to ensure the normal progress of the electrolysis process. The other part of the water is transported to the condensed water storage system (12) through the eighth water pipeline (108), and is integrated and recovered with the condensed water of the steam turbine generator (15), further optimizing the recycling of water resources. This reasonable distribution and reuse of water ensures that the water resource management within the system is more efficient, reduces the dependence on external water sources, and improves the resource utilization rate of the system. The present invention not only ensures the normal operation of the electrolytic hydrogen production device (6) by rationally allocating the water resources in the pure water storage tank (5), but also recycles the excess water into the condensed water storage system (12), effectively utilizing all the water resources in the system and reducing the water cost. This configuration further improves the water circulation efficiency, reduces the amount of sewage discharged, and has positive significance for environmental protection. At the same time, the water resource management mode of the system simplifies the water processing and transportation path, which helps to reduce the operation and maintenance costs of the system.

[0053] In some embodiments, the capacity and design of the pure water storage tank (5) can be adjusted according to the scale and water demand of the system, and storage tanks of different materials such as fiberglass or PE storage tanks can be used to meet different chemical and physical requirements. The layout of the seventh water pipeline (107) and the eighth water pipeline (108) can be further optimized, combined with automatic control valves and flow sensors to ensure the accurate allocation and efficient use of water resources between different systems. The recovery path of condensed water can also be adjusted according to site conditions, for example, it can be directly transported to other equipment that needs cooling or cleaning through pipelines to further expand the functions of the system. In order to improve the intelligence level of the system, water resource management software can be introduced to realize the full process automation control of water distribution, use and recovery.

[0054] Furthermore, the electrolytic hydrogen production system (6) also includes an oxygen storage tank (7). The electrolytic hydrogen production device (6) is connected to the oxygen storage tank (7) through an oxygen supply pipeline, the oxygen storage tank (7) is connected to the garbage incinerator (13) through a first oxygen supply pipeline (301), and is connected to the sewage biochemical system through a second oxygen supply pipeline (302). The oxygen storage tank (7) supplies oxygen to the outside through a third oxygen supply pipeline (303). The oxygen generated by the electrolytic hydrogen production device (6) is transported to the oxygen storage tank (7) through the oxygen supply pipeline for storage, and the oxygen storage tank (7) plays a role in balancing the supply and use of oxygen. The stored oxygen can be supplied to the garbage incinerator (13) through the first oxygen supply pipeline (301) to improve the incineration efficiency and calorific value; at the same time, oxygen is provided to the sewage biochemical system through the second oxygen supply pipeline (302) to enhance the aeration effect of the biochemical treatment and improve the sewage treatment efficiency. In addition, the oxygen storage tank (7) also supplies oxygen to the outside through the third oxygen supply pipeline (303), which expands the application range of oxygen, so that the oxygen generated by the system can be used for other industrial or medical purposes, and realizes the multi-level utilization of resources. The present invention realizes the effective management and distribution of the oxygen generated by the electrolytic hydrogen production system (6) by adding an oxygen storage tank (7). The reasonable storage and utilization of oxygen not only improves the combustion efficiency of the garbage incineration process and reduces pollutant emissions, but also enhances the biochemical effect of sewage treatment, and further optimizes the environmental performance of the overall system. The external supply function of oxygen expands the economic benefits of the system, provides an additional source of income for the system, and helps to reduce the environmental burden of other oxygen supply methods.

[0055] In some embodiments, the design of the oxygen storage tank (7) can adopt different materials and capacity configurations, such as stainless steel storage tanks, aluminum alloy storage tanks, etc., to adapt to different oxygen storage requirements and safety specifications. The design of the oxygen delivery pipeline can adjust the path and material according to actual needs, such as using corrosion-resistant materials or adding safety valves to ensure the stability and safety of oxygen delivery. The management of the oxygen storage tank (7) can also be combined with an intelligent control system to achieve real-time monitoring and automatic allocation of oxygen, and optimize the oxygen consumption and utilization efficiency of each part. In addition, according to different application scenarios, the oxygen storage tank (7) can also be connected with other equipment, such as high-pressure oxygen cylinders, oxygen concentrators, etc., to expand the application mode and scope of oxygen, and further enhance the flexibility and economic benefits of the system.

[0056] In some embodiments, the oxygen generated by the electrolytic hydrogen production device (6) (including but not limited to a proton exchange membrane pure water electrolytic hydrogen production device (6), an alkali electrolytic hydrogen production device (6), a solid oxide electrolytic hydrogen production device (6), an anion membrane electrolytic hydrogen production device (6) and other various electrolytic hydrogen production devices (6) formed by a single or multiple combination of hydrogen production devices (6)) is stored in an oxygen storage tank (7), and a portion of the oxygen enters the waste incinerator (13) through the first oxygen supply pipeline (301) as a combustion aid, effectively promoting the complete combustion of waste and reducing the amount of waste generated by combustion. Pollutants generated by insufficient oxygen supply, the first oxygen supply pipeline (301) is provided with a process valve and other designs for interlocking and adjusting the oxygen supply amount according to the garbage incineration situation; a part of the oxygen is provided to users through the third oxygen supply pipeline (303) or bottled for sale, thereby improving the economic benefits of the system; the other part of the oxygen enters the sewage biochemical system for aeration through the second oxygen supply pipeline (302), as pure oxygen, which can more effectively and quickly increase the dissolved oxygen of the biochemical system compared with compressed air, so as to improve the ability of the biochemical system to cope with large fluctuations in system load and enhance the operational stability of the biochemical system. The second oxygen supply pipeline (302) is provided with a process valve and other designs for interlocking and adjusting the oxygen supply amount according to the dissolved oxygen status of the living system. In the prior art, garbage incineration power plants usually use a blast method to supplement oxygen to the garbage incinerator (13) to incinerate garbage. When the blast is insufficient or the temperature of the incinerator (13) is unstable, insufficient combustion supplementation is likely to occur, resulting in the generation of pollutants such as dioxins, which seriously pollutes the atmospheric environment.

[0057] Furthermore, the electrolytic hydrogen production system (6) also includes a hydrogen purification device (8) and a hydrogen storage tank (9). The electrolytic hydrogen production device (6) is connected to the waste incinerator (13) through the first hydrogen transmission pipeline (401), and is connected to the hydrogen purification device (8) through the second hydrogen transmission pipeline (402). The hydrogen purification device (8) is connected to the hydrogen storage tank (9) through the third hydrogen transmission pipeline (403), the hydrogen storage tank (9) is connected to the waste incinerator (13) through the fourth hydrogen transmission pipeline (404), and the hydrogen storage tank (9) supplies hydrogen to the outside through the fifth hydrogen transmission pipeline. The hydrogen produced by the electrolytic hydrogen production device (6) is first directly supplied to the waste incinerator (13) through the first hydrogen transmission pipeline (401) to increase its combustion calorific value. Another part of the hydrogen is transported to the hydrogen purification device (8) through the second hydrogen transmission pipeline (402) for purification treatment to remove impurities and improve the purity of hydrogen. The purified hydrogen enters the hydrogen storage tank (9) for storage through the third hydrogen transmission pipeline (403). The stored hydrogen can not only continue to supply the waste incinerator (13) through the fourth hydrogen transmission pipeline (404), but also be supplied to the outside through the fifth hydrogen transmission pipeline for other industrial purposes or as clean energy. In this way, through the purification and storage links, efficient management and utilization of hydrogen resources are achieved. The present invention not only ensures the high-purity supply of hydrogen by introducing a hydrogen purification device (8) and a hydrogen storage tank (9), but also realizes the storage and distribution management of hydrogen, effectively improving the energy utilization efficiency of the system. The purified hydrogen is supplied to the waste incinerator (13), which helps to further improve the combustion efficiency and calorific value, while reducing the emission of pollutants. The presence of the hydrogen storage tank (9) also allows hydrogen to be flexibly allocated according to demand, thereby enhancing the hydrogen supply stability and safety of the system. In addition, the external hydrogen supply function expands the commercial application value of the system, increases the potential economic benefits for the system, and promotes the promotion and use of clean energy.

[0058] In some embodiments, the hydrogen purification device (8) can use different purification technologies, such as pressure swing adsorption (PSA), membrane separation technology or cryogenic fractionation, to meet different hydrogen quality requirements and production requirements. The design of the hydrogen storage tank (9) can select different materials according to the storage capacity requirements, such as high-pressure steel cylinders, composite storage tanks or liquid hydrogen storage tanks, to improve the safety and flexibility of storage. The design of the hydrogen transmission pipeline can be adjusted according to the actual application, such as adding hydrogen detection sensors and safety valves to ensure safety during the transportation process. For the external supply of hydrogen, it can also be combined with hydrogen filling stations or pipeline transportation methods to further expand the application scenarios and market potential of hydrogen and improve the overall benefits of the system.

[0059] In some embodiments, the produced hydrogen enters the hydrogen purification system (8) through the second hydrogen transmission pipeline (402), and is purified by deoxygenation and drying through a purification process (including but not limited to pressure swing adsorption, temperature swing adsorption, catalytic deoxygenation and other deep purification process systems). The purified hydrogen enters the hydrogen storage tank (9) through the third hydrogen transmission pipeline (403), and a part of it is transported to users for use or bottled for sale through the fifth hydrogen transmission pipeline, thereby improving the economic benefits of the system. The other part is transported to the waste incinerator (13) as a combustion gas through the fourth hydrogen transmission pipeline (404). Hydrogen, as a high-calorific value, reducing high-quality fuel, can effectively promote the complete combustion of garbage while improving the burning calorific value of the waste incinerator (13), ensuring the stability of the power generation while effectively reducing the generation of toxic gas pollutants. The fourth hydrogen transmission pipeline (404) is provided with a process valve that interlocks and adjusts the hydrogen delivery amount according to the waste incineration situation. In the existing technology, waste incineration power plants have unstable calorific value due to the large variability in the amount and type of waste. Therefore, it is necessary to add fossil fuels such as coal or natural gas during waste incineration to increase the calorific value and maintain the power generation capacity, which greatly increases resource consumption.

[0060] In some embodiments, when the waste incinerator (13) does not have high requirements for hydrogen purity, the combustion hydrogen used by the waste incinerator (13) can also be obtained through the first hydrogen transmission pipeline (401), thereby reducing processing costs. The first hydrogen transmission pipeline (401) is provided with a process valve that interlocks and adjusts the hydrogen delivery amount according to the waste incineration situation.

[0061] Furthermore, the waste heat boiler (14) is connected to the hydrogen purification device (8) via the second high-temperature steam gas transmission and return pipeline (502); the waste heat boiler (14) is connected to the pure water heat exchanger (4) via the third high-temperature steam gas transmission and return pipeline (503); the waste heat boiler (14) is connected to the electrolytic hydrogen production device (6) via the second high-temperature steam gas transmission and return pipeline (505). The high-temperature steam generated by the waste heat boiler (14) is transported to the hydrogen purification device (8) via the second high-temperature steam gas transmission and return pipeline (502) to provide the required heat energy and help gas separation and purity improvement during the purification process. The third high-temperature steam gas transmission and return pipeline (503) transports the high-temperature steam of the waste heat boiler (14) to the pure water heat exchanger (4), further optimizing the pure water temperature to ensure that it meets the operating conditions of electrolytic hydrogen production. Through the second high-temperature steam transmission pipeline (505), the steam from the waste heat boiler (14) is directly supplied to the electrolytic hydrogen production device (6) to support the temperature requirements of the electrolysis process and improve the electrolysis efficiency. This configuration ensures that the steam from the waste heat boiler (14) is maximized and fully supports multiple functions within the system. The present invention utilizes the high-temperature steam generated by the waste heat boiler (14) multiple times, which not only improves the working efficiency of the hydrogen purification device (8), the pure water heat exchanger (4) and the electrolytic hydrogen production device (6), but also significantly saves the input demand for external thermal energy and improves the overall energy utilization of the system. The diversified application of high-temperature steam promotes energy sharing and collaborative work among subsystems, reduces the system's dependence on external energy, and reduces operating costs. By fully utilizing waste heat, not only the operating performance of each device is improved, but also the overall environmental protection and energy-saving goals of the system are achieved, and waste heat emissions are effectively reduced.

[0062] In some embodiments, when the electrolytic hydrogen production device (6) is a solid oxide (SOEC) electrolytic hydrogen production device (6), since the electrolytic raw material of the solid oxide (SOEC) electrolytic hydrogen production device (6) is high-temperature steam at about 850°C, and the high-temperature steam of the waste heat boiler (14) is about 400°C to 450°C, the preheating process and energy consumption of the solid oxide (SOEC) electrolytic hydrogen production device (6) can be effectively reduced. The second high-temperature steam gas transmission pipeline (505) from the waste heat boiler (14) to the solid oxide (SOEC) electrolytic hydrogen production device (6) is provided with a process valve for interlocking control of the solid oxide (SOEC) electrolytic hydrogen production device (6).

[0063] In some embodiments, the waste heat boiler (14) is connected to the hydrogen purification device (8) through a second high-temperature steam gas transmission and return pipeline (502), and the heat required for purification (including but not limited to drying, deoxygenation, etc.) is provided to the hydrogen purification device (8) through the second high-temperature steam gas transmission and return pipeline (502), thereby improving the overall system energy utilization rate and reducing additional energy consumption. The second high-temperature steam gas transmission and return pipeline (502) is provided with a process valve interlocked with the hydrogen purification system (8) temperature control to adjust the high-temperature steam transmission flow rate.

[0064] In some embodiments, the waste heat boiler (14) is connected to the pure water heat exchanger (4) through a third high-temperature steam gas transmission return pipeline (503), and serves as a heat exchange heat medium to heat the pure water, ensuring that the temperature of the water entering the pure water storage tank (5) reaches the water temperature for rapid start-up of the electrolyzer in the electrolysis hydrogen production device (6), while ensuring that the system can still operate normally when the ambient temperature is below 0°C, eliminating the need for additional insulation design and reducing cost investment. The third high-temperature steam gas transmission return pipeline (503) is provided with a process valve that interlocks the pure water temperature control to adjust the high-temperature steam delivery flow rate.

[0065] Furthermore, the electrolytic hydrogen production system (6) also includes a power supply system (10). One end of the power supply system (10) is connected to the renewable energy through the first transmission line (701), and the other end is connected to the steam turbine generator (15) through the second transmission line (702). The power supply system (10) is connected to the electrolytic hydrogen production device (6) through the third transmission line (703) to provide electric energy for the electrolytic hydrogen production device (6). The power supply system (10) obtains electric energy from renewable energy (such as solar energy, wind energy, etc.) through the first transmission line (701) to supply the electrolytic hydrogen production device (6). At the same time, the power supply system (10) is also connected to the steam turbine generator (15) to obtain the electric energy generated by the steam turbine generator (15) through the second transmission line (702) to form a multi-source power supply network. The third transmission line (703) transmits the integrated electric energy to the electrolytic hydrogen production device (6) for driving the electrolysis process. In this way, the electrolytic hydrogen production system (6) can flexibly utilize the power resources from renewable energy and steam turbine generators (15), ensure continuous and stable power supply, maximize the use of renewable energy, and reduce dependence on traditional grid power. The present invention introduces a power system (10) to integrate the power of renewable energy and steam turbine generators (15), thereby constructing a diversified power supply system and improving the energy autonomy and sustainability of the electrolytic hydrogen production system (6). The use of renewable energy reduces the carbon footprint of electrolytic hydrogen production, meeting the requirements of environmental protection and energy conservation and emission reduction. At the same time, the system ensures the stable operation of the electrolytic hydrogen production process through multiple sources of electricity, reducing the risk of power outages. The integration of the power system (10) also improves the economic benefits of the overall system, reduces electricity costs, and achieves synergistic efficiency of the entire system by optimizing the distribution and utilization of electricity.

[0066] In some embodiments, the power system (10) may include an energy storage device, such as a battery pack or a supercapacitor, to balance the volatility of renewable energy generation and ensure stable power supply to the electrolytic hydrogen production device (6). The source of electricity can also be expanded to other forms of renewable energy, such as biomass energy or geothermal energy, to further diversify the energy structure of the system. The design of the transmission line can adjust the cable specifications and materials according to the distance and power demand to ensure the efficiency and stability of power transmission. In addition, the power system (10) can integrate smart grid technology to achieve dynamic monitoring and optimal distribution of power flow, improve the responsiveness and operating efficiency of the electrolytic hydrogen production system (6), and adapt to different load requirements.

[0067] Furthermore, the sludge composting bin (11) is connected to the garbage incinerator (13) via a second sludge conveying pipeline (202), and the sludge is used as an auxiliary fuel for the garbage incinerator (13) to improve the calorific value of incineration. The sludge generated after the sewage biochemical system is treated is transported to the sludge composting bin (11) for composting treatment, and at the same time, part of the composted sludge is transported to the garbage incinerator (13) via the second sludge conveying pipeline (202). As an organic substance with a high calorific value, sludge is used as an auxiliary fuel in the garbage incinerator (13), which not only helps to improve the calorific value of the incinerator (13), but also can stabilize the heat output of the incineration process. By utilizing the sludge as a resource, the incinerator (13) can achieve more efficient energy recovery, while reducing the use of other fossil fuels, and further optimizing the combustion efficiency of the incinerator (13). The present invention realizes the resource utilization of sludge by incinerating sludge as an auxiliary fuel, reducing the external treatment cost of sludge and the potential pollution to the environment. Adding sludge as an auxiliary fuel to the waste incinerator (13) can improve the incineration calorific value and incineration efficiency, increase the heat output of the incinerator (13), and help further improve the efficiency of the waste heat recovery system. At the same time, the high calorific value of the sludge reduces the dependence on other fuels, reduces the operating cost of the system, and enhances the environmental protection benefits of the overall system.

[0068] In some embodiments, the design of the sludge composting bin (11) can adopt different composting processes, such as aerobic composting or anaerobic composting, and select the appropriate method according to the sludge properties and processing requirements to improve the composting efficiency and product quality. For the process of transporting the sludge to the garbage incinerator (13), different conveying equipment, such as screw conveyors, pumping systems, etc., can be used to meet the requirements of different sludge physical properties. The pretreatment method of the sludge can also be adjusted, such as dehydration, drying or crushing, to improve the combustion efficiency of the sludge during the incineration process. For the combustion control of the incinerator (13), an automated control system can be introduced to optimize the mixing ratio and combustion parameters of the sludge and garbage to ensure the stability and efficiency of the incineration process. In addition, the harmful components that may be contained in the sludge should be controlled by detection and pretreatment methods to ensure the safety and environmental protection of the incineration process.
