Description

Technical fields:

[0001] This invention relates to the field of new energy production and energy development and utilization. It is applicable to areas such as rural revitalization, urban air pollution control, effective containment of global warming, and achieving complementary energy transitions. It effectively addresses the problem of biogas production in high-altitude and cold regions, and the efficient collection of large quantities of biogas (methane gas) emitted from septic tanks in cities, towns, and residential areas, which pollutes the atmosphere and contributes to the greenhouse heat island effect (more than 80 times that of an equivalent amount of CO2). It effectively solves the problem of providing clean fuel for cooking, heating, showering, and disinfection, and effectively addresses the issue of returning large amounts of biomass residue to the fields as organic farmyard manure, turning waste into treasure.

[0002] Specifically, it involves a new type of efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility. Background technology:

[0003] Since the 1950s, most provinces in southern my country have organized and promoted the construction of conventional biogas digesters to varying degrees through the government at all levels, for use by urban and rural residents for cooking, lighting, heating, and other daily needs.

[0004] In conjunction with the vision put forward by the inventor at the Ninth China Green Industry Development Summit held at the China Science and Technology Hall on January 3, 2017, that "to solve the problem of global warming, we must first solve the problems of decarbonized power generation, decarbonized district heating, decarbonized metal smelting, and the electrification of transportation."

[0005] Based on the inventor's patent applications for a gas / oil-fired multi-functional energy-saving stove (patent number ZL2013102766824, 2013), a biomass (coal)-fired multi-functional energy-saving stove (patent number ZL2013102766735), and a dual-fuel (oil / gas) multi-functional energy-saving stove (patent number ZL201403588307, 2014), it was found during the promotion process that a small number of units using biogas as fuel experienced performance issues due to small gas storage capacity, low gas pressure, and low calorific value. While the inventor's multi-functional energy-saving stove works very well with natural gas, its performance with biogas is less satisfactory. Furthermore, in spring, autumn, and winter, the low temperatures prevent normal biogas production. Conventional biogas digester construction cannot solve the problems of biogas production and effective storage, as well as pressure regulation, in low-temperature seasons and areas, thus failing to meet the year-round, all-weather gas demand of residents. Currently, the vast majority of rural residents still burn wood, crop stalks, and coal as fuel to solve their cooking and heating problems, which seriously pollutes the environment.

[0006] In 2015, 2016, and 2017, the inventor conducted on-site investigations of biogas construction and promotion by agricultural departments at all levels of government across the country. After analyzing the reasons, on September 29, 2025, the inventor submitted an application to the State Intellectual Property Office for a "High-Efficiency, Energy-Saving, Environmentally Friendly, Oxygen-Enhancing, and Combustion-Assisting Gas and Oil Dual-Use Multifunctional Energy-Saving Stove" which saves more than 70% of fuel compared to conventional stoves. The application number is 2025114107977 and the document number is 2025121600996800. The plan includes the vast areas of high-altitude, cold, and high-latitude regions, as well as areas lacking natural gas as fuel, in the promotion plan for the new multifunctional biogas energy-saving stove.

[0007] With the depletion of fossil fuels and rising temperatures, the human living environment is severely impacted, necessitating the search for new energy sources and an energy transition. Currently, there is no new facility capable of effectively collecting the large quantities of methane gas produced from the decomposition of fallen leaves and crop straw returned to the fields, as well as from the decomposition of human and animal waste and other sewage discharged into septic tanks by cities, towns, residential communities, rural households, and livestock farms. This massive release of methane gas into the atmosphere pollutes the environment, contributing to a greenhouse heat island effect more than 80 times that of an equivalent amount of CO2, and is a major factor contributing to global warming, urgently requiring remediation. Summary of the Invention

[0008] Biomass energy is the only known natural alternative to fossil fuels. Against this backdrop, there is an urgent need for a new, clean, environmentally friendly, and efficient system for the production, conversion, and storage of biogas in rural areas, as well as for the collection and storage of biogas from urban septic tanks. Biogas's main component is methane (CH4), the same as natural gas, produced by the decomposition of organic matter underground in the absence of air. It is combustible and is primarily found in swamps, coal mines, and oil wells; it is sometimes referred to as "artificial natural gas." However, when released into the air, it pollutes the atmosphere and damages its structure. To achieve this transformation from waste to resources, effectively addressing the shortage of new energy fuels, curbing global warming, and powerfully promoting the early realization of energy transition goals are crucial.

[0009] To effectively address the problems of low gas production in conventional biogas digesters, lack of gas production during cold seasons, in low-temperature areas, and at high altitudes, and to effectively solve the issues of large amounts of biogas (CH4) released into the atmosphere from the decomposition of fallen leaves and crop straw returned to the fields, as well as the large amounts of methane (CH4) released from the decomposition of human and animal excrement and other sewage from cities, towns, communities, rural households, and all livestock farms, thus polluting the environment and wasting new energy sources, this solution aims to effectively address the growing depletion of fossil fuels and the need to burn wood, crop straw, and other biomass fuels and coal for cooking, heating, and other necessities for urban and rural residents, thereby eliminating environmental pollution!

[0010] This invention provides a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility that turns waste into treasure, produces new energy, and strongly promotes energy transformation.

[0011] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0012] A novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility comprises a thermally insulated biogas reaction and storage system, an organic biomass crushing, decomposition, stirring, and tumbling system, an automatic feeding system, a remote intelligent networked gas storage system, an intelligent water level and gas pressure regulation system, an intelligent temperature regulation and control system, an automatic sewage discharge system, an automatic gas storage pressurization system, an urban septic tank biogas collection system, an urban sewage pipeline biogas re-separation system, a user gas consumption system, and other hardware facilities, as well as a remote intelligent control platform system and other software facilities.

[0013] Preferably, a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility, namely a heat-insulated biogas reaction and storage system, uses a metal profile as a supporting framework, with corrosion-resistant metal plates welded together internally and externally. The gaps in the middle are filled with polyurethane foam for overall insulation, reinforcement, and heat preservation. Alternatively, it can be integrally cast with reinforced concrete, using angle steel and structural steel as a supporting framework, with corrosion-resistant metal plates welded together for the inner packaging, and the gaps in the middle filled with polyurethane foam for overall heat preservation, creating a sealed storage volume. This achieves heat insulation and effectively solves the problem of conventional biogas digesters failing to ferment, decompose, and produce biogas in low-temperature seasons, low-temperature areas, and high-altitude regions. This is one of the core technologies of this invention. Figure 1 As shown.

[0014] Preferably, a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility includes an organic biomass crushing, decomposition, stirring, and tumbling system. This system comprises an electrically powered propeller-type crushing and cutting unit with built-in insulation fixed to the bottom of an insulated biogas decomposition reaction and storage volume. Multiple outlets, angled upwards at specific directions, surround the inner wall of the insulated biogas reaction and storage volume. A submersible pump or external water pump is mounted on a pipe with an inlet at the lower end of the pipe. These pumps are electrically connected to a relay controller with an embedded sensor terminal, which is communicatively connected to a remote central intelligent control system platform. The electrically powered propeller-type crushing and cutting unit must be positioned below the minimum control liquid level. The remote central intelligent control system has a locking device; the relay controller can only be activated when the liquid level is below the minimum control liquid level, allowing the electrically powered propeller-type crushing and cutting unit to operate. This system crushes and stirs organic residues, tumbling internal wastewater, preventing surface crusting, facilitating the full fermentation and decomposition of organic residues, and ensuring smooth discharge from the pipes.

[0015] Preferably, the automatic feeding system of a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility comprises a bidirectional tracked conveyor device electrically connected to a relay controller with embedded sensor terminals, which is communicatively connected to a power motor and a remote central intelligent control system platform. This device is placed within a safe distance of the feed inlet, which is angled and faces upwards, on the outer wall of the insulated biogas decomposition reaction and storage volume, and is protected from sun and rain. A safety guardrail must be installed at the feed inlet to effectively prevent people and animals from falling in. When equipment maintenance or replacement is required, only qualified technicians wearing oxygen cylinders and gas masks may enter after safe drainage of wastewater and strong ventilation.

[0016] Preferably, a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility, namely a remote intelligent networked gas storage system, uses a pipeline with a one-way valve and a flow meter to connect the insulated biogas reactor storage volume to an external dedicated gas storage volume. Embedded pressure sensors placed in the insulated biogas reactor storage volume and the dedicated gas storage volume are respectively connected to a remote central intelligent system control platform, which facilitates real-time monitoring of gas production and storage status and enables remote intelligent control functions.

[0017] Preferably, the intelligent water level and gas pressure regulation system of a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility connects an embedded liquid level sensor, built into the insulated biogas reactor storage volume, to a remote central intelligent control system platform. It also electrically connects a first solenoid valve on the bottom water inlet pipe of the insulated biogas reactor storage volume to a relay controller with an embedded liquid level sensor terminal, which is also connected to the remote central intelligent control system platform. This achieves the function of raising the liquid level and compressing the biogas density.

[0018] Preferably, the intelligent temperature regulation and control system of a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility connects an embedded temperature sensor built into the insulated biogas reactor storage volume to a remote central intelligent control system platform. An external solar collector (solar water heater) is electrically connected to a second electromagnetic valve on a pipe connecting a ring-shaped heat exchange coil built into the inner wall of the insulated biogas reactor storage volume to a relay controller with an embedded temperature sensor terminal, which is also connected to the remote central intelligent control system platform. This system raises the temperature of the mixture of organic matter and water within the insulated biogas reactor storage volume to a controllable range, ensuring sufficient fermentation and decomposition of the organic matter and the full release of biogas (methane CH4). This is one of the core technologies of this invention.

[0019] Preferably, the automatic sewage discharge system of a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility connects a third solenoid valve or head pump equipped with a PLC (Programmable Logic Controller) or PMC (Programmable Motion Controller) and connected to the sewage discharge pipe at the bottom of the insulated biogas reactor storage volume. This valve is electrically connected to a relay controller with a sensor terminal that communicates with a remote central intelligent control system platform. The PMC has more powerful functions, encompassing all the functions of a PLC. During setup, the discharge volume must be greater than the input volume to maintain a controllable and ideal liquid level, while also achieving automatic sewage discharge.

[0020] Preferably, the automatic pressurization system of the novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility integrates an embedded pressure sensor and a liquid level sensor, both built into a dedicated gas storage volume, which are connected to a remote central intelligent control system platform. A fourth solenoid valve connected to the bottom of the dedicated gas storage volume to the tap water inlet pipe, and a fifth solenoid valve connected to the bottom of the dedicated gas storage volume to the sewage outlet pipe, are electrically connected to a relay controller with a sensor terminal connected to the remote central intelligent control system platform, thereby achieving the automatic pressurization function.

[0021] Preferably, a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility, namely the urban septic tank biogas collection system, is implemented as follows: ① The lower end of the wastewater pipes from each household in the city to the sealed septic tank in the community is placed below the lowest control liquid level of the sealed septic tank. This effectively prevents methane gas (CH4, biogas) from escaping into the atmosphere through this pipe. The upper end of this pipe in each community is set to allow air to enter. After the methane gas and sewage are discharged from the septic tank, no negative pressure will be formed, which facilitates the control of the liquid level in the septic tank, the control of sewage discharge, and the control of methane gas transportation. ② Connect the bottom of the septic tank to the municipal sewage branch pipe via a pipe equipped with a PLC (Programmable Logic Controller) or PMC (Programmable Motion Controller) sixth solenoid valve, whose opening degree can be adjusted. During setup, the discharge volume must be greater than the input volume. Normally, the liquid level in the septic tank is controlled within an effective range, allowing sewage and waste to fully ferment. During peak water usage periods (mealtimes, etc.), the sixth solenoid valve opens after a delay, causing the water level in the septic tank to rise to the highest warning position. This compresses the methane gas, opening the one-way valve and squeezing it into the dedicated gas storage volume. The system then automatically opens the sixth solenoid valve, automatically adjusting the discharge degree to quickly discharge sewage to the controllable minimum water level. When the amount of sewage entering the septic tank from each community is large, the sixth solenoid valve automatically opens to the highest setting for discharge, and vice versa. When discharging sewage from a septic tank in a lower location to a higher location, an auxiliary lift pump must also be installed on this pipe. ③ Connect the top of the sealed septic tank with a pipe equipped with a one-way valve and a flow meter to the urban biogas transmission branch pipeline. Install a smart control system with intelligent liquid level sensors inside the septic tank for intelligent control of high and low liquid levels. ④ A combination of wired and wireless methods is used to electrically and communicatively connect the solenoid valves, relay controllers with sensor terminal controllers, and intelligent liquid level sensors to the remote central intelligent control system platform. Wastewater from cooking and other processes discharged into the sealed septic tank during each meal raises the liquid level to the set maximum. As the liquid level rises, the density and pressure of biogas within the sealed septic tank increase, automatically opening the one-way valve on the top gas pipeline to release methane gas into the city's biogas transmission network, which then enters the city's natural gas pipeline network or is transported to a dedicated gas storage capacity for later dispatch, serving the residents. When the biogas in the sealed septic tank is exhausted, the intelligent control system immediately opens the adjustable sixth solenoid valve at its bottom, maximizing and rapidly discharging the wastewater from the sealed septic tank to the lowest controlled liquid level, inputting it into the city's main sewage pipeline, and then into the next biogas (methane) separation module, repeating the cycle continuously. ⑤ During the transportation of wastewater from septic tanks in urban residential areas, multiple residential areas in one region can be transported to one septic tank for centralized treatment.

[0022] Preferably, a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility, specifically a biogas re-separation system for urban sewage pipelines, operates on a principle similar to that of an urban septic tank biogas collection system. The specific implementation is as follows: ① The embedded liquid level sensor built into the large-volume sealed volume into which the sewage pipes of multiple urban communities converge is connected to the remote central intelligent control system platform. The sixth solenoid valve installed on the sewage pipe at the bottom of the large-volume sealed volume and the relay controller with the embedded liquid level sensor terminal connected to the remote central intelligent control system platform are electrically connected. ② Connect the gas transmission pipeline with a one-way valve and flow meter from the top of the large-volume sealed volume to the external biogas transmission main pipeline. ③ As described above in the "Urban Septic Tank Biogas Collection System", the sewage output branch pipes of each sealed septic tank in the city, together with the built-in embedded liquid level sensor and the external relay controller with sensor terminal, communicate with the remote central intelligent control system platform in a combination of wired and wireless methods. The sealed turnover energy storage volume is connected to the minimum control liquid level below the electrical connection. ④ A vent pipe with an open top is installed below the lowest control liquid level of the sealed large energy storage volume, leading directly to an external position higher than this sealed volume, while preventing sewage from overflowing from this pipe. This achieves control of the liquid level within the sealed energy storage volume, methane gas transportation, and sewage discharge without allowing methane gas to escape into the atmosphere through this pipe. ⑤ Install the sixth solenoid valve with intelligent control function of PLC or PMC programmable logic controller with adjustable opening degree at the bottom of the sealed turnover energy storage volume and on the pipeline connecting to the urban sewage transportation. ⑥ This biogas re-separation module during urban sewage transportation can be connected in series in multiple urban areas, allowing sewage from multiple locations to be collected in one place. It enables multiple decompositions and fermentations of urban sewage during transportation, and the methane gas produced is then separated and collected multiple times, turning waste into treasure.

[0023] Preferably, a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility for user gas consumption connects a dedicated gas storage volume or an insulated biogas reaction and storage volume to the user gas consumption unit via pipelines equipped with automatic pressure regulating valves. Several leakage sensors and solenoid valves installed at key locations are electrically and communicatively connected to a remote central intelligent control system platform, enabling remote intelligent control functionality.

[0024] Preferably, the remote intelligent control software platform system for a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility adopts a hybrid application development approach using HTML5, Android, and HTML5 cloud website + APP client. It utilizes a hybrid application and mixed language development approach using Java, JavaScript, HTML5, and SQL statements. The system includes modules for location query, liquid level monitoring, gas leakage monitoring, weather forecasting, online monitoring, address book, early warning, inspection, gas pressure monitoring, temperature monitoring, gas dispatching, and big data analysis and statistics. The software platform system is composed of wired / wireless connections. The software intelligently controls corresponding equipment based on the control system list, ensuring one-to-one correspondence and unified coding for seamless switching. Each insulated biogas reaction and storage volume is uniformly coded with a QR code; users can scan this QR code with their mobile phones to access the user interface for convenient use. The remote central intelligent control system platform monitors the overall production, usage, and fault status of all production bases in the entire network system, enabling scientific management and intelligent dispatching. In addition to the functions available to regular users, advanced users of the system also have the following additional functions: 1. User management: users can query regular user information, reset regular usernames and passwords, and delete regular user accounts. 2. Adding or modifying contact information.

[0025] Its specific functions are as follows: ① Location Query Module: Users can view the status of insulated biogas reactor storage capacity production bases through two methods. First, the status of the insulated biogas reactor storage capacity and dedicated gas storage capacity is displayed on a map, which can be zoomed in and out. Second, users can select different areas to query, and a list will display the location and status of the insulated biogas reactor storage capacity or dedicated gas storage capacity within that area, including longitude, latitude, altitude, village / group, street, and house number. ② Liquid Level Monitoring Module: Users can view the water level status information in the insulated biogas reactor storage volume or dedicated gas storage volume through two methods. First, by selecting a specific insulated biogas reactor storage volume or dedicated gas storage volume, the water level over 24 hours will be displayed via a line graph, especially the water level in urban septic tanks. Second, by selecting the production base where different insulated biogas reactor storage volumes or dedicated gas storage volumes are located, the real-time water level status over 24 hours will be displayed in tabular form. This query function also provides historical water level review functionality. ③ Leakage Detection Module: Leakage sensors are installed at relevant nodes and key locations such as methane gas connection pipelines and storage volumes, and are connected to the remote central intelligent control system platform via wired / wireless communication. The system enables intelligent management, and when a leak is detected, the electromagnetic valve at that location is immediately shut off, and the platform automatically notifies the nearest maintenance personnel for emergency repairs. ④ Weather forecast module: can provide users with 10-15 day weather forecasts for the region. ⑤ Online module: Cameras and pH sensors are installed in key parts of biogas production and storage bases such as insulated biogas reaction storage volume, dedicated gas storage volume, and urban and community septic tanks to monitor the operation of the entire system online and observe whether the sewage can be discharged into farmland. ⑥ Address Book Module: Search for the contact information of the person in charge of different organizations. ⑦ Early warning module: When the water level or gas pressure in the storage volume or dedicated gas storage volume of a certain insulated biogas reaction exceeds the warning level, the system will notify the user to check and take immediate action through sound and vibration. It supports user functions such as mobile phone text message, WeChat, and QQ. ⑧ Inspection Module: Users can upload inspection forms to the backend database in two ways. One way is by scanning a QR code to access the inspection form, filling it out, and submitting it to the backend. Each insulated biogas reactor storage volume or dedicated gas storage volume has a unique QR code. The other way is to directly select the unified code of the specified insulated biogas reactor storage volume or dedicated gas storage volume within the remote central intelligent control system platform software, fill out the form, upload it to the backend, and enable the function of periodically updating the form for the current stage. ⑨ Gas pressure monitoring module: Through an embedded gas pressure sensor built into the insulated biogas reactor storage volume or a dedicated gas storage volume, it provides users with real-time information such as gas pressure and gas storage volume. ⑩ Temperature monitoring module: Through the temperature sensor built into the insulated biogas reactor storage volume or dedicated gas storage volume, it provides users with real-time information on the temperature, decomposition, fermentation and other related statuses of the mixed reaction liquid. Gas dispatching module: In the entire remote central intelligent control system platform network system, it dispatches the regional biogas (methane gas) usage and operation status in real time. The big data analysis and statistics module collects and statistically analyzes various parameters such as water level, methane gas volume, and gas pressure in each insulated biogas digester or dedicated gas storage volume, as well as flow meters and cameras installed on the gas transmission pipelines of each dedicated and sealed gas storage volume. This data facilitates real-time collection and statistical analysis of methane gas inventory and the production capacity of each biogas digester, enabling accurate settlement. Comprehensive analysis of network scheduling issues provides a scientific basis for energy strategic decision-making by governments at all levels.

[0026] Preferably, the biogas (methane gas) produced by this novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility is a gas produced by the decomposition of organic matter in the absence of air under specific temperature and humidity conditions. It is combustible, and its main component is methane, consistent with the composition of natural gas, hence it is known in the industry as "artificial natural gas." This is a renewable, clean, and environmentally friendly new energy source with wide applications, making it a preferred product for achieving energy transition. Biomass energy is the only known naturally available alternative to fossil fuels, and biogas (methane gas) is one such alternative. my country has abundant solar and water resources, a developed agricultural and pastoral sector, and rich agricultural and pastoral biomass energy. The application of renewable energy has become a major direction for energy diversification, energy transition, and promoting China's low-carbon economy and future sustainable development.

[0027] Its principles and applications are as follows:

[0028] First, energy recycling and utilization Globally, fossil fuels such as coal, oil, and natural gas are increasingly depleted and non-renewable, leading to a severe energy crisis. Clean energy production capacity is limited and cannot effectively replace the burning of wood, crop straw, and coal for cooking, heating, and daily life in rural areas. Furthermore, it cannot effectively address the environmental pollution caused by sewage and waste from rural households and livestock farms. Large quantities of straw, leaves, and vines left over from harvesting grains, oilseeds, vegetables, and other cash crops in rural areas are not properly disposed of and are returned to the fields. The resulting large amounts of methane gas (CH4) are released into the atmosphere, damaging atmospheric structure and severely polluting the environment. According to an authoritative report in *China Newsweek*, the greenhouse heat island effect of methane gas is more than 80 times that of an equivalent amount of CO2, making it one of the main culprits of global warming.

[0029] To address the aforementioned issues, a new type of highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility utilizes the leftover straw, leaves, and vines from the harvest of various grains, oilseeds, vegetables, and other cash crops in rural areas. These are then fed into insulated biogas reactors and storage volumes. Large quantities of crop straw from the harvest season can be packaged and stored, and added in batches as needed. Under the action of specially cultivated bacterial strains, the straw undergoes thorough fermentation and decomposition, effectively and completely separating and storing methane gas for use. The organic residue is then returned to the fields as high-quality organic fertilizer for crop growth, further contributing to the production of grains, oilseeds, vegetables, and other cash crops. This cyclical process ensures an inexhaustible supply of methane gas.

[0030] This technology can effectively separate, collect, and utilize the methane gas (CH4) produced from the decomposition of sewage and waste in septic tanks of cities, towns, residential communities, and livestock farms. This prevents its release into the atmosphere, transforming harmful emissions into beneficial uses, improving the quality of life in cities, towns, and communities, and enhancing residents' happiness index.

[0031] Second, energy conversion and storage This new type of high-efficiency, environmentally friendly, and intelligent biogas production, collection, and storage facility utilizes a remote intelligent control software platform system based on HTML5 and Android. It is a hybrid application developed using an HTML5 cloud website and an APP client, employing a hybrid application and language development approach combining Java, JavaScript, HTML5, and SQL. The system includes modules for location query, liquid level monitoring, gas leakage monitoring, weather forecasting, online monitoring, address book, early warning, inspection, gas pressure monitoring, temperature monitoring, gas dispatching, and big data analysis and statistics. The software platform system combines wired and wireless connections, effectively enabling networked intelligent management of all biogas production facilities at the county, city, province, and national levels. It centrally dispatches biogas produced in grain-producing areas with widespread straw distribution, as well as biogas collected in large and medium-sized cities, for use in other cities and rural areas, achieving energy conversion and storage, and providing static and dynamic, local and overall regulation and dispatching functions.

[0032] Third, it provides a basis for scientific decision-making by leaders at all levels of government. This new type of efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility, with its remote central intelligent control system platform's big data analysis and statistics module, and its integrated use with various pressure sensors, temperature sensors, level sensors, flow meters, etc., collects and calculates various data, providing leaders at all levels of government with real-time information on stored biogas volume, analysis, and decision-making on energy strategies, thus providing a scientific basis. The user-facing APP allows for convenient access to and operation of the intelligent management system, facilitating both use and maintenance.

[0033] Fourth, it enables users to meet their needs for clean cooking and heating.

[0034] This new type of highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility, with its intelligent temperature control system and intelligent gas storage system, effectively solves the problem of insufficient or no gas production in high-altitude, cold regions during the low-temperature season, thus failing to meet the large-scale gas demand of users. In grain-producing areas with abundant crop straw, more of these facilities can be built to produce and store methane gas. Excess gas can be supplied to the city's natural gas network, ensuring that users' needs for clean cooking, heating, and other functions are met.

[0035] Fifth, energy-saving and environmentally friendly characteristics.

[0036] This new, highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility is the most advanced and intelligent biogas production, collection, and storage facility in the world today. It first solves the problem of disposing of large amounts of organic crop residues from farmland, turning waste into treasure. It prevents the methane gas released during the decomposition of organic matter from being emitted into the atmosphere, thus preventing global warming. Instead, it collects and effectively decomposes the methane gas for reuse. It also effectively collects large amounts of methane gas released into the atmosphere during the composting, fermentation, and decomposition of domestic wastewater and livestock manure from urban and rural residents, purifying the air, beautifying the environment, and improving air quality. The remaining organic residue is returned to the fields as high-quality farmyard manure, effectively improving soil structure and serving agricultural production. It truly achieves energy saving, cleanliness, environmental protection, and sustainable development, strongly ensuring the sustainable and high-quality development of the circular economy.

[0037] Compared with the prior art, the technical solution of the present invention has the following incomparable advantages:

[0038] This invention relates to a novel, highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility. It features an insulated biogas reaction and storage volume, and an intelligent temperature control system. This effectively replaces the various biogas digester construction methods gradually promoted globally since the 1950s, effectively solving the problems of no gas production in low-temperature seasons and low gas production, low pressure, and small storage capacity in high-temperature seasons. Based on the problems discovered during the promotion of the inventor's previous multi-functional series of energy-saving stoves, and summarizing the shortcomings of conventional biogas digester construction and use, this invention, developed through scientific exploration, innovation, repeated demonstrations, scientific analysis, and careful design, combined with previous practical experience, offers performance unmatched by any other similar facility worldwide.

[0039] The implementation of this new, highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility first separates and collects the methane gas produced by septic tanks in cities, towns, and residential areas. This methane is then piped to a dedicated storage tank and connected to the network for users to use at any time. Currently, with the ongoing construction of beautiful villages, the implementation of this invention not only solves the problem of clean fuel and effectively promotes energy transformation, but also addresses environmental pollution, effectively protecting the environment and improving the quality of life and happiness index. Its effectiveness is unparalleled by any other similar facility in the world.

[0040] This invention relates to a novel, highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility. It utilizes a remotely networked intelligent control system platform software, achieving full automation. This includes remote control via an app, PLC or PMC operation adjustment, networked gas transmission, automatic feeding, wastewater discharge, temperature control, gas production, and gas supply. It is commercially viable, allowing for centralized production by a company and decentralized use, ensuring scientific management and meeting modern needs. Furthermore, it provides real-time energy inventory data to governments at all levels, offering reliable data for leaders' scientific energy strategy decisions—a feature unmatched by conventional biogas facilities.

[0041] This invention presents a novel, highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility with a scientifically sound structural design and a very broad market prospect. The equipment, which the inventors initially invested in, has demonstrated significant effectiveness and low construction costs, offering long-term benefits from a one-time investment, aligning with the national low-carbon, environmentally friendly, and energy transition strategy. The implementation of this invention will effectively and powerfully promote the achievement of energy transition goals and deserves rapid and comprehensive promotion by governments at all levels.

[0044] To make the objectives, technical solutions, functions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the description and accompanying drawings. It should not be construed that the present invention is limited to the following embodiments.

[0045] Without departing from the design, concept, and functional implementation of this invention, any modifications and technical improvements to this invention in this field should be within the protection scope of the claims of this invention.

[0046] The “storage volume” or “gas storage volume” mentioned in this invention refers to an energy storage tank, gas storage box or gas storage vessel that is not limited by circular, square or other irregular structures. Example:

[0047] This embodiment discloses a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility. As a preferred embodiment of this technical solution, it is a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage technology that can effectively solve the problem of treating organic crop residues in rural areas. It is applicable to the construction of beautiful villages, urban air pollution control, effectively curbing global warming, and achieving complementary energy transitions. It can effectively solve the problem of biogas production in high-altitude and cold regions, and the effective collection of large quantities of biogas (methane) emitted from septic tanks in various cities, towns, and communities, which pollutes the atmosphere and contributes to the greenhouse heat island effect (more than 80 times that of an equivalent amount of CO2). It effectively solves the problem of residents needing clean fuel for cooking, heating, showering, and disinfection, and effectively solves the problem of returning large amounts of biomass residues to the fields as organic farmyard manure, turning waste into treasure.

[0048] To achieve the above objectives, and considering the issues encountered during the previous construction and promotion of biogas digesters, such as low gas production, lack of gas production in low-temperature seasons, and no gas production in low-temperature areas, this invention provides a novel, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility. This facility comprises a thermally insulated biogas reaction and storage system, an organic biomass crushing, decomposition, stirring, and tumbling system, an automatic feeding system, a remote intelligent networked gas storage system, an intelligent water level and gas pressure regulation system, an intelligent temperature regulation and control system, an automatic sewage discharge system, an automatic gas storage and pressurization system, an urban septic tank biogas collection system, an urban sewage pipeline biogas re-separation system, a user gas consumption system, and other hardware facilities, as well as a remote intelligent control platform system and other software facilities.

[0049] This invention relates to a novel, highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility. Its working principle involves an automatic feeding system 3 feeding organic biomass into an insulated biogas reactor storage volume. Under the operation of intelligent water level, pressure regulation, and temperature control systems, and with the action of specialized bacterial strains within the insulated biogas reactor storage volume, the organic biomass is rapidly and fully fermented and decomposed, quickly producing biogas (methane CH4). Once the methane gas in the insulated biogas reactor storage volume reaches a certain pressure, a one-way valve on the pipeline connecting the insulated biogas reactor storage volume and a dedicated gas storage volume automatically opens, allowing a large quantity of methane gas to enter the dedicated gas storage volume for high-density, large-volume storage, providing users with readily available high-quality methane gas year-round, solving fuel problems. This technology can be extended to the field of biogas separation, collection, re-separation, and re-collection in urban septic tanks, effectively collecting and reusing biogas produced by all septic tanks, achieving rapid realization of energy transition goals!

[0050] To achieve the above objectives, this invention provides a novel, highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility. Its insulated biogas reaction and storage system comprises a central support frame constructed from woven and welded metal profiles, including angle steel, bar steel, and rebar. Both the inner and outer layers are constructed from welded metal sheets treated with anti-corrosion measures, preferably stainless steel for durability. The gaps between the support frames are filled with liquid polyurethane foam for overall insulation and reinforcement. Alternatively, it can be integrally cast with reinforced concrete, then filled with polyurethane foam, and secured with a support frame woven and welded from angle steel, rebar, and other steel profiles, with an inner insulation layer made of anti-corrosion treated metal sheets. Alternatively, an insulating coating can be integrally applied to the inner wall to achieve thermal insulation, resulting in an insulated biogas reaction and storage volume that is completely sealed except for the automatic feeding port. Furthermore, the automatic feeding port (upper port) for organic biomass input must be above the highest liquid level of the insulated biogas reactor storage volume. The connection point between the automatic feeding port and the insulated biogas reactor storage volume (lower port) must be below the lowest liquid level for biogas production within the storage volume to effectively prevent methane gas escape from the feeding port. A sewage pipe with a solenoid valve is also installed at the bottom of the insulated biogas reactor storage volume. The mixture of fully fermented and decomposed organic residue and wastewater is discharged from a relatively higher position to a lower position, where the intelligent timed control system of the remote central intelligent control platform automatically opens the solenoid valve. If the mixture of organic residue and water is to be discharged to a higher position and remotely, a booster pump must be installed on the discharge pipe and electrically connected to the remote central intelligent control system platform. This effectively solves the problem of conventional biogas digesters failing to ferment, decompose, and produce biogas in low-temperature seasons, low-temperature areas, and high-altitude regions. Figure 1 As shown.

[0051] Furthermore, the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility includes an organic biomass crushing, decomposition, stirring, and tumbling system. This system comprises two electrically powered propeller-type crushing and cutting units (two with built-in insulation fixed to the bottom of the insulated biogas decomposition reaction and storage volume), and multiple outlets (inlet pipes at a certain angle and direction) surrounding the inner wall of the insulated biogas reaction and storage volume. Submersible pumps or external water pumps are installed on these pipes, which are electrically connected to a relay controller with embedded sensor terminals, communicating with a remote central intelligent control system platform. This system must be positioned below the minimum control liquid level, and the system's minimum liquid level must be above the effective minimum control liquid level, for the remote central intelligent control system to activate. This system crushes and stirs organic residues, tumbling internal wastewater to prevent surface crusting, facilitating the full fermentation and decomposition of organic matter, and ensuring smooth discharge from the pipeline. Depending on the actual site conditions, the shape and size of the insulated biogas reactor storage volume determine the number of units to be installed. One or more units can be installed, and two electric propeller-type crushing and cutting units can be connected to an external solar power distribution box, mains power, and remote central intelligent control system platform for electrical and communication connections.

[0052] Furthermore, the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility features an automatic feeding system 3. This system incorporates a bidirectional tracked conveyor, electrically connected to an external solar-powered distribution box or mains power, and a relay controller with embedded sensor terminals, which communicates with the remote central intelligent control system platform. This conveyor is placed within a safe distance of the feed inlet, which is angled and faces upwards, on the outer wall of the insulated biogas decomposition reaction storage volume, and is protected from sun and rain. This allows the organic matter transported by the bidirectional electric tracked conveyor to quickly slide into the insulated biogas reaction storage volume from the feed inlet. In suitable areas, during crop harvesting, it is even better if the harvesting equipment automatically crushes and compresses the crop straw into blocks or cylinders, transporting it to the insulated biogas reaction storage volume for floating, soaking, fermentation, crushing, and decomposition. This also facilitates storage and stacking, awaiting input into the insulated biogas reaction storage volume for decomposition and fermentation. The feed inlet must be equipped with a safety guardrail and locking device to effectively prevent people and animals from falling in. When equipment needs repair or replacement, only professional technicians wearing oxygen cylinders and gas masks may enter after the sewage and waste have been safely drained and the ventilation has been strong.

[0053] Furthermore, the new, highly efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility features a remote intelligent networked gas storage system. This system uses pipelines equipped with one-way valves and flow meters to connect the insulated biogas reactor storage volume to an external dedicated gas storage volume. Embedded pressure sensors within both the insulated biogas reactor storage volume and the dedicated gas storage volume are connected to a remote central intelligent system control platform. Combined with cameras, this allows for real-time monitoring of gas production and storage, enabling automatic control. In centralized production areas, large insulated biogas production volumes can be connected to multiple dedicated gas storage volumes, or multiple insulated biogas reactor storage volumes can be connected to a single dedicated gas storage volume. Depending on local terrain conditions, installation can be centralized or decentralized. Its function is to automatically open the one-way valve when the methane gas produced in the insulated biogas reactor storage volume reaches a certain capacity and pressure, transferring the methane gas to the dedicated gas storage volume for later use. Embedded pressure sensors are installed at the top of both the insulated biogas reactor storage volume and the dedicated gas storage volume, communicating with a remote central intelligent control system platform via a combination of wired and wireless methods. The remote central intelligent control system platform software, through pre-set function calculation formulas, automatically calculates and statistically analyzes the individual methane gas production and reserves, as well as the total production and reserves, based on data collected from various sensors in the insulated biogas reactor storage volume or dedicated gas storage volume. This facilitates commercial settlement and provides accurate and scientific data for leaders at all levels of government to understand the actual situation, make energy strategy decisions, and scientifically allocate gas resources. Each user is equipped with an APP user terminal and intelligent management system to monitor, process, and utilize gas resources in real time to meet user needs.

[0054] Furthermore, the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility features an intelligent water level and pressure regulation system. An embedded liquid level sensor, built into the insulated biogas reactor storage volume, communicates with a remote central intelligent control system platform. The system also electrically connects the first solenoid valve 5 on the bottom water inlet pipe of the insulated biogas reactor storage volume to a relay controller with an embedded liquid level sensor terminal, also connected to the remote central intelligent control system platform. This system raises the liquid level, compresses the biogas, and increases its density. When the batch of organic matter in the insulated biogas reactor storage volume has fully fermented, decomposed, and released methane gas, reaching a certain pressure, and a large amount of methane gas needs to be stored in a dedicated gas storage volume, the system automatically opens the solenoid valve to inject liquid, raising the liquid level in the insulated biogas reactor storage volume, reducing the space occupied by methane gas, increasing the methane gas density and pressure, and automatically opening the one-way valve on the dedicated gas storage volume pipeline to allow the methane gas to enter the dedicated gas storage volume. A flow meter, in conjunction with a camera, automatically records the data. Under the action of the one-way valve, after the liquid level in the storage volume of the insulated biogas reaction occurs drops, the methane gas in the dedicated gas storage volume will not flow back.

[0055] Furthermore, the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility features an intelligent temperature regulation and control system. This system connects an embedded temperature sensor, built into the insulated biogas reactor storage volume, to a remote central intelligent control system platform. It also electrically connects an external solar collector 6 (solar water heater) to a second solenoid valve 7 on a pipe connected to the annular heat exchange coil built into the inner wall of the insulated biogas reactor storage volume, and to a relay controller with an embedded temperature sensor terminal, also connected to the remote central intelligent control system platform. This system raises the temperature of the mixture of organic matter and water within the insulated biogas reactor storage volume to a controllable range, ensuring sufficient fermentation and decomposition of the organic matter and the full release of methane gas. It also maintains the temperature of the mixed reaction water-soluble substances within the insulated biogas reactor storage volume within an ideal temperature range that allows for rapid and effective decomposition of methane gas. During the day, the system fully utilizes solar energy resources. Solar collector 6 (solar water heater) produces hot water, which circulates to the annular heat exchange coils surrounding the walls of the insulated biogas reactor storage volume. This allows heat exchange between the coils and the mixture of water and organic matter within the storage volume, raising the temperature to a controllable range. When the maximum controllable temperature is reached, the system automatically closes the second solenoid valve 7, stopping hot water circulation. When the temperature drops below the minimum controllable temperature, the system automatically opens the second solenoid valve 7, resuming hot water circulation and heat exchange. This ensures that the organic matter within the insulated biogas reactor storage volume can fully ferment and decompose year-round, even in frigid regions and high-latitude areas, producing sufficient methane gas. This is one of the core technologies of this invention.

[0056] Furthermore, the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility features an automatic sewage discharge system. This system connects a third solenoid valve (8) equipped with a PLC or PMC and adjustable opening, or a pump, located on the sewage pipe at the bottom of the insulated biogas reactor storage volume, to a relay controller with a sensor terminal that communicates with a remote central intelligent control system platform. Wastewater and waste from the insulated biogas reactor storage volume are discharged to a lower elevation using the third solenoid valve (8). If the discharge is to a higher elevation, a booster pump is installed. Maintaining a controllable ideal liquid level, the system allows for the timed discharge and transport of the fully decomposed and fermented organic residues from the insulated biogas reactor storage volume to distant locations. This allows the wastewater to be used for irrigation of crops, vegetables, and fruits through underground runoff and infiltration, or as high-quality farmyard manure for hydroponics, producing organic grains, vegetables, and fruits, turning waste into treasure, and achieving intelligent automatic sewage discharge.

[0057] Furthermore, the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility features an automatic gas pressurization system. An embedded pressure sensor and a liquid level sensor, both built into a dedicated gas storage volume, are connected to a remote central intelligent control system platform. The system connects to two electromagnetic valves: a fourth solenoid valve (9) on the bottom of the dedicated gas storage volume, which connects to a tap water inlet pipe (not drinking water, but including wastewater discharged by the system), and a fifth solenoid valve (10) on the bottom of the dedicated gas storage volume, which connects to a sewage outlet pipe. These valves are electrically connected to a relay controller with a sensor terminal, also connected to the remote central intelligent control system platform. When the gas pressure in the dedicated gas storage volume is too low to meet user needs, the embedded pressure sensor sends a command to the remote central intelligent control system platform to open the fourth solenoid valve (9), injecting tap water, raising the liquid level in the dedicated gas storage volume, compressing the methane gas, and increasing its density. When a large amount of methane gas produced in the insulated biogas reactor storage volume needs to be transferred to a dedicated gas storage volume, the remote central intelligent control system platform automatically opens the fifth solenoid valve 10 on the drainage pipe of the dedicated gas storage volume. When the liquid level reaches a certain point, the embedded sensor sends a command to the remote central intelligent control system platform to close the fifth solenoid valve 10. This prevents the liquid in the dedicated gas storage volume from being emptied and allowing methane gas to escape into the atmosphere through the drainage pipe, truly achieving automatic pressurization and intelligent control functions.

[0058] Furthermore, new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facilities, such as urban septic tank biogas collection systems, are being developed. Figure 2 As shown, the specific steps are as follows: ① The lower end of the wastewater pipe 11 from each household in the city to the sealed septic tank 14 in the community is placed below the lowest control liquid level of the sealed septic tank. This effectively prevents methane gas CH4 (biogas) from escaping into the atmosphere through this pipe. The upper end of this pipe in each community is open to allow air to enter the bottom. After the methane gas and sewage are discharged from the septic tank, negative pressure will not be formed, which facilitates the control of the liquid level in the septic tank, sewage discharge, and methane gas transportation. ② Connect the sixth solenoid valve 13, with adjustable opening, from the bottom of the septic tank to the municipal sewage branch pipe using a pipe equipped with a PLC (Programmable Logic Controller) or PMC (Programmable Motion Controller). During setup, the sewage discharge volume must be greater than the sewage input volume. Normally, the liquid level in the septic tank is controlled within an effective range, allowing sewage and waste to fully ferment. During peak water usage periods (e.g., during meals), when the water level in the septic tank rises to the highest warning position, the sixth solenoid valve opens after a delay, raising the sewage level in the septic tank. This compresses the methane gas, opening the one-way valve 4 and forcing the methane gas into the dedicated gas storage volume 9. When the sewage level reaches the highest warning position, the system automatically opens the sixth solenoid valve 13 at its maximum opening, quickly discharging the sewage to the controllable minimum water level, and then discharging normally. When the amount of sewage entering the septic tank from each community is large, the sixth solenoid valve 13 automatically opens to the maximum discharge level, and vice versa. When discharging wastewater from a lower-lying septic tank to a higher elevation, an auxiliary lift pump must be installed on this pipeline. This pump rapidly discharges the wastewater from the sealed septic tank to the lowest control level, then into the main municipal sewage pipeline, and finally into the next biogas (methane gas) separation module, repeating the cycle continuously. ③ Connect the top of the sealed septic tank to the urban biogas transmission branch pipeline using a pipe with a one-way valve 4 and a flow meter. Install a smart control system with intelligent liquid level sensors inside the septic tank for intelligent control of high and low liquid levels. ④ The electromagnetic valve, the relay controller with sensor terminal, and the intelligent liquid level sensor are electrically and communicatively connected to the remote central intelligent control system platform using a combination of wired and wireless methods. ⑤ During the transportation of wastewater from septic tanks in urban residential areas, multiple residential areas in one district can be transported to one septic tank. The bottom of the septic tank is equipped with a pipeline connected to the main urban sewage transportation pipeline via a sixth solenoid valve 13 with PLC or PMC adjustable opening. After the opening is adjusted, the flow rate into the main pipeline must be greater than the sewage input at the front end to prevent sewage from overflowing from the biogas transmission pipeline. ⑥ The top of the sealed, reusable energy storage volume is connected to the city's biogas transmission network via a pipe equipped with a one-way valve and a flow meter. The sealed, reusable energy storage volume is equipped with a high / low liquid level control system with an intelligent liquid level sensor, and is connected to a remote central intelligent control system platform. This enables the timed and complete separation, collection, and transportation of methane gas.

[0059] Furthermore, the principle of the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility, specifically its urban sewage pipeline biogas re-separation system, is similar to that of the urban septic tank biogas collection system, such as... Figure 3 As shown, the specific method is as follows: ① The embedded liquid level sensor built into the large-volume sealed volume 15 into which the sewage pipes of multiple urban communities converge is connected to the remote central intelligent control system platform. The sixth solenoid valve 13 with adjustable opening degree installed on the sewage pipe at the bottom of the large-volume sealed volume and the relay controller with embedded liquid level sensor terminal connected to the remote central intelligent control system platform are electrically connected to realize the automation function. ② Connect the gas transmission pipeline with one-way valve 4 and flow meter from the top of the large-volume sealed volume 9 to the external biogas transmission main pipeline or dedicated gas storage volume to realize the function of automatic gas transmission and storage. ③ Install the lower end of the upward-opening air intake pipe 12 below the lowest control liquid level of the sealed septic tank. ④ In conjunction with the above

[0058] , the sewage output branch pipes of each sealed septic tank in the city are connected to the remote central intelligent control system platform via a combination of wired and wireless communication with the built-in embedded liquid level sensor and the external relay controller with sensor terminal. The sealed turnover energy storage volume is connected to the lowest control liquid level below the electrical connection. ⑤ A vent pipe 12 with an open top is installed below the lowest control liquid level of the sealed large energy storage volume and leads directly to the outside at a position higher than this sealed volume, while preventing sewage from overflowing from it. This achieves control of the liquid level in the sealed energy storage volume, methane gas transportation, and sewage discharge without allowing methane gas to escape into the atmosphere through this pipe. ⑥ Install the sixth solenoid valve 13, which has the intelligent control function of a PLC or PMC programmable logic controller with adjustable opening degree, on the connection pipeline between the sealed turnover energy storage volume and the urban sewage transportation pipeline. ⑦ This biogas re-separation module during urban sewage transportation can be connected in series in multiple urban areas, allowing sewage from multiple locations to be collected in one place, providing comprehensive coverage of the entire city. It enables multiple decompositions and fermentations during urban sewage transportation, and the methane gas produced is repeatedly separated and collected, turning waste into treasure. ⑧ Its principle, besides urban use, can be extended to other areas: Multiple biogas separation modules can be connected in series during urban sewage transportation to further decompose all sewage during pipeline transport. The methane gas produced by fermentation is then thoroughly separated multiple times, collected, and reused, turning waste into treasure once again. The organic matter in residential septic tanks consists of daily household waste, wastewater, and excrement discharged within 24 hours. This waste then enters the city's sewage pipeline and is discharged to the sewage treatment plant. Because the residence time in the septic tank is relatively short and there is no heating system, the methane gas produced by fermentation and decomposition is not as dense as that produced by the insulated biogas reaction storage volume described in this invention. However, given the large population of a city, the total amount of methane gas produced by all septic tanks is substantial. The cumulative amount of methane gas produced by all urban septic tanks in towns, counties, cities, provinces, and even nationwide is enormous and cannot be ignored. In areas with suitable conditions, urban septic tank systems can be modified according to the core technology of this invention for insulated biogas construction. Wastewater and waste discharged from urban septic tanks contain a large amount of methane gas that needs to be decomposed. This methane continues to ferment and decompose in the transport pipelines. Before being transported to sewage treatment plants or rural farmland, the methane gas in the sewage pipelines is separated and collected again. The mixture of sewage and waste flows into a large, sealed container. There is a certain drop between the inlet and outlet of the sealed container, and an intelligent high / low water level control system regulates the water level within the sealed container. The top of the sealed container is connected to the main urban gas pipeline or a dedicated gas storage container 9 via a pipe equipped with a one-way valve 4. This effectively separates and collects all the methane gas. At regular intervals, the discharge valve of the large, sealed container is closed, raising the water level inside the sealed container and allowing all the methane gas to pass through the one-way valve 4 into the dedicated gas storage container 9 or the main gas pipeline. This method can be used in multiple stages on sewage transport pipelines to completely separate and collect methane gas with excellent results. The special gas storage volume described in this invention can be used in series. Methane gas in the insulated biogas reaction storage volume 9 is introduced through a one-way valve. After reaching a certain pressure, liquids such as sewage can be introduced to raise its level, squeezing the methane gas into the next special gas storage volume. Then, sewage is discharged to free up gas storage space, allowing methane gas to enter. When a certain amount is reached, it is automatically compressed again for effective storage.

[0060] Furthermore, the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility, as described in its user gas system, connects a dedicated gas storage volume or an insulated biogas reactor storage volume to the user gas unit via pipelines equipped with automatic pressure regulating valves. Several leak sensors and solenoid valves installed at key locations are electrically and communicatively connected to a remote central intelligent control system platform, enabling remote intelligent control. Several leak sensors and solenoid valves are installed at critical locations such as the pipeline interface with the user, and are connected to the remote central intelligent control system platform. When a leak sensor detects a leak in the pipeline or a negative pressure condition within the pipeline, the solenoid valves automatically shut off, completely eliminating the risk of accidents. Special note: When a negative pressure condition is detected in the gas pipeline, ignition is strictly prohibited to prevent backfire and potential explosion of the gas pipeline or storage device. External motors or other electrical equipment must not be installed within a safe distance of the dedicated gas storage volume or insulated biogas reactor storage volume containing methane gas to completely eliminate potential hazards.

[0061] Furthermore, the new, efficient, environmentally friendly, and intelligent biogas production, collection, and storage facility utilizes a remote intelligent control software platform system based on HTML5 and Android. It is developed using a hybrid application of HTML5 cloud website and APP client, employing a hybrid application and language development approach combining Java, JavaScript, HTML5, and SQL statements. The system includes modules for location query, liquid level monitoring, gas leakage monitoring, weather forecasting, online monitoring, address book, early warning, inspection, gas pressure monitoring, temperature monitoring, gas dispatching, and big data analysis and statistics. The software platform system combines wired and wireless connections. Based on the control system list, the software intelligently controls the corresponding equipment, ensuring a one-to-one correspondence and unified coding for seamless switching. Each insulated biogas reaction and storage volume is uniquely coded with a QR code. Users scan this QR code with their mobile phones to access the user interface and monitor the status of that production base. The remote central intelligent control system platform then monitors the overall production, usage, and fault information of all production bases across the entire network, enabling scientific management and intelligent dispatching. In addition to the functions available to regular users, advanced users of the system also have the following additional functions: 1. User management: They can query regular user information, reset usernames and passwords, and delete regular user accounts. 2. Adding or modifying contact information.

[0062] Its specific functions are as follows: ① Location Query Module: Users can view the status of insulated biogas reactor storage capacity production bases through two methods. First, the status of the insulated biogas reactor storage capacity and dedicated gas storage capacity is displayed on a map, which can be zoomed in and out. Second, users can select different areas to query, and a list will display the location and status of the insulated biogas reactor storage capacity or dedicated gas storage capacity within that area, including longitude, latitude, altitude, village / group, street, and house number. ② Liquid Level Monitoring Module: Users can view the water level status information in the insulated biogas reactor storage volume or dedicated gas storage volume through two methods. First, by selecting a specific insulated biogas reactor storage volume or dedicated gas storage volume, the water level over 24 hours will be displayed via a line graph, especially the water level in urban septic tanks. Second, by selecting the production base where different insulated biogas reactor storage volumes or dedicated gas storage volumes are located, the real-time water level status over 24 hours will be displayed in tabular form. This query function also provides historical water level review functionality. ③ Leakage Detection Module: Leakage sensors are installed at relevant nodes and key locations such as methane gas connection pipelines and storage volumes, and are connected to the remote central intelligent control system platform via wired / wireless communication. The system enables intelligent management, and when a leak is detected, the electromagnetic valve at that location is immediately shut off, and the platform automatically notifies the nearest maintenance personnel for emergency repairs. ④ Weather forecast module: can provide users with weather forecasts for the region for more than 10 days. ⑤ Online module: Cameras and pH sensors are installed in key parts of biogas production and storage bases such as insulated biogas reaction storage volume, dedicated gas storage volume, and urban and community septic tanks to monitor the operation of the entire system online, remotely observe the pH concentration of wastewater, and automatically decide whether it can be discharged into farmland immediately. ⑥ Address Book Module: Search for the contact information of the person in charge of different organizations. ⑦ Early warning module: When the water level or gas pressure in the storage volume or dedicated gas storage volume of a certain insulated biogas reaction exceeds the warning level, the system will notify the user to check and take immediate action through sound and vibration. It supports user functions such as mobile phone text message, WeChat, and QQ. ⑧ Inspection Module: Users can upload inspection forms to the backend database in two ways. One way is by scanning a QR code to access the inspection form, filling it out, and submitting it to the backend. Each insulated biogas reactor storage volume or dedicated gas storage volume has a unique QR code. The other way is to directly select the unified code of the specified insulated biogas reactor storage volume or dedicated gas storage volume within the remote central intelligent control system platform software, fill out the form, upload it to the backend, and enable the function of periodically updating the form for the current stage. ⑨ Gas pressure monitoring module: Through an embedded gas pressure sensor built into the insulated biogas reactor storage volume or a dedicated gas storage volume, it provides users with real-time information such as gas pressure and gas storage volume. ⑩ Temperature monitoring module: Through the temperature sensor built into the insulated biogas reactor storage volume or dedicated gas storage volume, it provides users with real-time information on the temperature, decomposition, fermentation and other related statuses of the mixed reaction liquid. Gas Dispatch Module: In the entire remote central intelligent control system platform network, the real-time dispatch of biogas (methane gas) usage and operation is monitored. The big data analysis and statistics module uses data such as water level, methane gas volume, and gas pressure in each insulated biogas digester or dedicated gas storage volume, as well as flow meters and cameras installed on the gas transmission pipelines of each dedicated and sealed gas storage volume, to provide real-time statistics on methane gas inventory and biogas production capacity of each sealed volume, facilitating settlement. It also provides comprehensive analysis of network scheduling issues and a scientific basis for energy strategic decision-making by governments at all levels.

[0063] The above embodiments are in line with the energy conservation and emission reduction strategies of all countries in the world, and will effectively and rapidly promote the achievement of global energy transition goals, serve human society, improve the quality of life and happiness index of residents, and governments at all levels should organize comprehensive promotion as soon as possible.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0065] The present invention can be well implemented according to the above embodiments. It is worth noting that, based on the above structure, principle, and design, even if some non-substantial modifications or refinements are made to the present invention to solve the same technical problem, if the technical solution adopted is substantially consistent with the present invention, it should also be within the protection scope of the present invention.
