Description

Technical Field

[0001] This invention relates to the field of energy storage heating technology, and in particular to a nitrogen-free and carbon-reducing energy storage heating system. Background Technology

[0002] Driven by the global energy transition and carbon neutrality goals, the industrial sector's demand for cleaner and more efficient energy is growing. Traditional gas-fired heating systems are widely used in industries such as petroleum, chemical, and metallurgy; however, they inevitably produce large amounts of nitrogen oxides (NOx) and carbon dioxide (CO2) during combustion, becoming a significant source of environmental pollution and greenhouse gas emissions. How to reduce NOx emissions and improve energy efficiency while ensuring a stable industrial heat supply has become a pressing technical challenge.

[0003] In existing technologies, traditional systems rely on direct combustion in gas-fired furnaces, which have low combustion efficiency and low heat conversion rate, resulting in high gas consumption and high operating energy consumption. Due to the lack of an oxygen-assisted combustion mechanism, gas-fired furnaces burn nitrogen in the air at high temperatures, which easily generates a large amount of nitrogen oxides (NOx), resulting in large flue gas emissions that are difficult to meet standards. NOx not only causes serious environmental pollution, but also increases the cost and pressure on enterprises in environmental protection. If traditional gas-fired furnaces need to improve combustion efficiency or reduce emissions, it is usually necessary to replace core equipment or install complex denitrification devices, which are costly to modify and have a long construction period.

[0004] In addition, traditional systems lack effective filtration during gas storage and transportation, causing impurities in nitrogen or oxygen to directly enter the gas storage tank or heating furnace. Long-term operation will cause equipment wear, blockage or corrosion, increase maintenance frequency, shorten equipment life and affect the overall stability of the system. Therefore, this application discloses a nitrogen-free and carbon-reducing energy storage and heating system. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a nitrogen-free and carbon-reducing energy storage and heating system to solve the problems of gas-fired heating furnaces burning nitrogen in the air at high temperatures, which easily generates a large amount of nitrogen oxides (NOx), resulting in large flue gas emissions that are difficult to meet standards, and the lack of effective filtration during gas storage and transportation, which causes impurities in nitrogen or oxygen to directly enter the gas storage tank or heating furnace, leading to equipment wear, blockage or corrosion during long-term operation.

[0016] The beneficial effects of this invention are:

[0017] 1. This nitrogen-free, carbon-reducing energy storage and heating system, by setting up nitrogen and oxygen processing units and supporting gas storage tanks, utilizes surplus wind and solar power or off-peak electricity to produce nitrogen and oxygen, efficiently converting fluctuating renewable energy into stable industrial resources, avoiding energy waste. Nitrogen is directly applied to the nitrogen injection oil recovery process in oil fields, significantly improving crude oil recovery rate, increasing oil field production while reducing the cost of purchased nitrogen, and reducing the high energy consumption and environmental pollution caused by traditional nitrogen production methods. Oxygen is used in the auxiliary combustion process of gas-fired heating furnaces, further improving fuel combustion efficiency and reducing gas consumption, achieving comprehensive and efficient utilization of resources. This solution not only fully utilizes the potential of wind and solar power, but also improves energy utilization in industrial processes, reduces production costs, helps promote the deep integration of green energy and industry, and provides an innovative path for the consumption of renewable energy.

[0018] The oxygen produced by the nitrogen and oxygen processing unit is directly injected into the combustion zone of the gas-fired heating furnace. By optimizing the combustion process, the gas combustion efficiency is significantly improved, reducing gas consumption by more than 60% and reducing NOx generation, effectively reducing flue gas emissions by more than 70% and ensuring 100% compliance with NOx emission standards. Compared with the high investment in replacing equipment, this solution only requires the addition of oxygen injectors to achieve the transformation, which has significant economic benefits and operability. Oxygen-assisted combustion not only improves the thermal energy conversion rate, but also extends the service life of the equipment, reduces maintenance costs and downtime. In addition, efficient combustion reduces the emission of greenhouse gases and pollutants.

[0019] 2. This nitrogen-free, carbon-reducing energy storage and heating system incorporates a filter assembly. This assembly ensures that the nitrogen or oxygen generated by the nitrogen and oxygen processing unit is efficiently filtered before entering the storage tank, guaranteeing gas purity, reducing impurities from entering the storage tank or subsequent equipment, and preventing equipment damage and blockage. Impurities are intercepted layer by layer through the filter cartridge and multi-stage filter rings, maintaining smooth airflow during the filtration process and ensuring stable filtration efficiency. The filter cartridge is self-cleaning by rotating under the drive of a motor, using centrifugal force to throw impurities attached to the filter cartridge to the bottom of the filter chamber, achieving automatic cleaning, reducing maintenance frequency, and extending the service life of the filter assembly. The self-cleaning function of the filter assembly prevents airflow blockage. Even when there is a large accumulation of impurities in the filter, the gas can be directly discharged from the bottom of the filter chamber by disconnecting the filter outlet pipe, restoring the system's smooth flow.

[0020] 3. This nitrogen-free and carbon-reducing energy storage and heating system is equipped with a pressure detection component. This component monitors the internal pressure of the gas storage tank in real time, ensuring that the system operates within a safe pressure range and effectively avoiding safety risks caused by tank overpressure. The return pipe allows excess gas inside the storage tank to automatically return to the pressurization pump for secondary pressurization when the pressure increases, increasing the gas density in the storage tank, optimizing storage space, and avoiding waste. The rate meter monitors the return process in real time to ensure a stable return rate. It works in conjunction with the pressurization pump to maintain internal pressure balance. A third valve precisely controls the gas return path to prevent excessive or too rapid return, ensuring stable system operation. Throughout the process, operators can adjust the operating status in a timely manner based on the pressure gauge and rate meter data to prevent system failures caused by excessively high or low gas pressure.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0034] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] like Figures 1 to 9 As shown, the nitrogen-free carbon reduction energy storage heating system includes a nitrogen and oxygen processing unit and a gas-fired heater. The nitrogen and oxygen processing unit is used to produce nitrogen and oxygen by utilizing surplus wind and solar power and off-peak electricity. The nitrogen and oxygen processing unit is also equipped with several gas storage tanks 2 for storing nitrogen and oxygen. The nitrogen processed by the nitrogen and oxygen processing unit is used for the nitrogen injection oil displacement process in the oil layer, and the oxygen processed by the nitrogen and oxygen processing unit is used to assist the combustion in the gas-fired heater. The oxygen injection port of the gas-fired heater is equipped with an oxygen injection nozzle.

[0036] During periods of surplus wind and solar power or when electricity is scarce, the nitrogen and oxygen processing units start up, using electrolysis or pressure swing adsorption (PSA) technology to separate air and produce nitrogen and oxygen. The generated nitrogen is stored in storage tank 2 and transported to the oilfield nitrogen injection system when needed. The nitrogen is injected into the oil layer to improve oil production efficiency. Oxygen enters the gas-fired heater through pipelines, and oxygen injectors at the injection port directly inject oxygen into the combustion zone, making the gas combustion more complete, improving combustion efficiency, and reducing NOx formation. During the entire system operation, the production and storage of oxygen and nitrogen are automatically controlled by the nitrogen and oxygen processing units, ensuring a continuous and stable supply of nitrogen to the gas-fired heater and the oilfield. The nitrogen and oxygen processing units utilize off-peak electricity or surplus wind and solar power to produce nitrogen and oxygen, effectively converting renewable energy into industrial production resources, reducing electricity waste, and lowering the operating energy consumption of the gas-fired heater. Oxygen is directly introduced during the combustion process, improving combustion efficiency and ensuring complete combustion of the fuel gas. This reduces the likelihood of nitrogen reacting with oxygen to generate NOx under high-temperature conditions, resulting in a flue gas emission reduction of over 70% and 100% compliance with NOx emission standards. Furthermore, the processed nitrogen is directly used in oilfield nitrogen injection enhanced oil recovery processes, increasing oil production and reducing the need for purchased nitrogen, thus lowering oilfield operating costs. This also avoids the high energy consumption and pollution emissions associated with traditional nitrogen production. In addition, the gas-fired heater only requires the addition of oxygen injectors, avoiding the high costs of replacing or upgrading core equipment. The modification investment is low, easy to implement, and highly economical and feasible. Oxygen-assisted combustion not only improves combustion efficiency but also enhances the overall thermal energy conversion rate of the gas-fired heater, reducing fuel gas consumption and achieving energy savings of over 60%, extending equipment lifespan, and reducing equipment maintenance and downtime.

[0037] like Figure 2 , Figure 3 , Figure 4 As shown, a mounting bracket 1 for mounting the gas storage tank 2 is provided on one side, and an air inlet 3 for inlet and an air outlet 4 for outlet are provided on one side of the gas storage tank 2. A filter assembly is provided at one end of the gas storage tank 2. The filter assembly is used to filter the nitrogen or oxygen processed by the nitrogen and oxygen processing unit. A pressure detection assembly is also provided at the bottom of the mounting bracket 1. The pressure detection assembly is used to monitor the gas pressure inside the gas storage tank 2 in real time.

[0038] Nitrogen or oxygen generated by the nitrogen and oxygen processing unit enters the storage tank 2 through the delivery pipeline. First, it passes through the filter component at one end of the storage tank 2 to filter out impurities and particles in the gas, ensuring that the gas entering the storage tank is pure. The gas enters the storage tank 2 through the inlet 3 for storage. During the gas filling and storage process, the pressure detection component monitors the pressure status inside the tank in real time. When needed, the gas is delivered from the outlet 4 to the gas heating furnace or oilfield nitrogen injection equipment. The storage tank 2 is fixed on the mounting bracket 1 to ensure that the storage tank is stable and easy to maintain and replace.

[0039] like Figures 6 to 9 As shown, the filter assembly includes a filter tank 5 fixedly installed on one side of the mounting bracket 1. A filter inlet pipe 6 is provided on one side of the top of the filter tank 5, and the filter inlet pipe 6 is connected to the outlet of the nitrogen / oxygen processing unit. A filter outlet channel 7 is provided on one side of the bottom of the filter tank 5, and a filter outlet pipe 14 is provided at the bottom of the filter outlet channel 7. A three-way connector 16 is connected to the other end of the filter outlet pipe 14. A first control valve 15 is provided between the filter outlet pipe 14 and the three-way connector 16. One end of the head 16 is connected to a gas storage inlet pipe 17. A pressure pump 18 is installed on the side of the mounting bracket 1 away from the filter tank 5. The pressure pump 18 is connected to the gas storage inlet pipe 17. A second gas storage inlet pipe 19 is installed on the other side of the pressure pump 18 and is connected to the air inlet 3. A second control valve 20 is installed between the air inlet 3 and the second gas storage inlet pipe 19 for control. A filter chamber 10 is installed on one side inside the filter tank 5. A filter element cylinder 13 is rotatably installed inside the filter chamber 10. A rotating shaft 11 is fixedly installed on the side away from the filter inlet pipe 6. A rotating motor 12 is provided on the side of the filter tank 5 away from the filter inlet pipe 6. The output end of the rotating motor 12 is fixedly connected to the rotating shaft 11. The filter cartridge 13 includes two positioning discs 27 rotatably installed inside the filter cavity 10. A positioning post 28 is fixedly installed between the two positioning discs 27. The rotating shaft 11 passes through one of the positioning discs 27 and is fixedly connected to the middle of the positioning post 28. A filter cylinder 29 is sleeved on the outer surface of the positioning post 28. A filter ring 30 is sleeved on the outer surface of the filter cylinder 29. The two ends of the filter ring 30 are fixedly connected to the two positioning discs 27 respectively. A sealing bearing 8 is sleeved on the end of the filter inlet pipe 6 near the filter cartridge 13. A multi-directional air inlet pipe 9 is nested on the other end of the sealing bearing 8. The other end of the multi-directional air inlet pipe 9 is arranged in a multi-channel configuration. A number of connecting pipes 26 are provided through one end of another positioning disc 27. The other end of the multi-directional air inlet pipe 9 is connected to the number of connecting pipes 26 in a multi-channel configuration.

[0040] When the nitrogen and oxygen processing unit is started and produces nitrogen or oxygen, the gas enters the filter inlet pipe 6 through the delivery pipeline, flows into the filter tank 5 installed on the bracket, and enters the multi-directional inlet pipe 9 through the sealed bearing 8. It then enters the filter cartridge 13 through multiple channels. Driven by the rotating motor 12, the rotating shaft 11 drives the filter cartridge 13 to rotate, so that the gas is evenly distributed inside the filter cartridge 13. It is filtered through the filter ring 30 and the filter cartridge 29 step by step. The pure nitrogen or oxygen flows into the filter outlet channel 7 and is delivered to the three-way connector 16 through the filter outlet pipe 14. When the first control valve 15 is opened, the gas enters the pressurizing pump 18 through the first gas storage inlet pipe 17. After being pressurized, it flows into the second gas storage inlet pipe 19 and finally enters the gas storage tank 2 for storage through the second control valve 20.

[0041] During the gas filtration process, if the system detects a large amount of impurities accumulated on the surface of the filter cartridge 13 or filter ring 30, the operator or automatic system first closes the first control valve 15 to temporarily stop the gas output from the filter outlet pipe 14. Then, the connection between the filter outlet pipe 14 and the filter outlet channel 7 is disconnected, and the filter outlet channel 7 is opened to allow the gas to be discharged from the bottom of the filter chamber 10. At this time, the rotating motor 12 is started to drive the filter cartridge 13 to rotate at high speed. The centrifugal force generated by the rotation throws the impurities on the surface of the filter cartridge 13 to the bottom of the filter chamber 10 and discharges them through the filter outlet channel 7, restoring the permeability of the filter. After cleaning, the filter outlet channel 7 is closed again, the filter outlet pipe 14 is connected, and the first control valve 15 is opened to allow the gas to re-enter the gas storage tank 2, thus completing the filtration and storage process.

[0042] like Figures 3 to 5 As shown, the pressure detection assembly includes a gas storage pressure pipe 21 located at one end of the gas storage tank 2, which is connected to the interior of the gas storage tank 2. A pressure gauge 22 is located at the other end of the gas storage tank 2. A return pipe 23 is also located on one side of the middle of the gas storage pressure pipe 21. The other end of the return pipe 23 is connected to the other end of the tee connector 16. A connecting pipe is located on the side of the gas storage pressure pipe 21 near the pressure gauge 22, which is connected to the return pipe 23. A third valve 25 is located at both connection points between the gas storage pressure pipe 21 and the return pipe 23. A rate meter 24 is located at one end of the return pipe 23.

[0043] After the nitrogen and oxygen processing unit starts operating, the generated nitrogen or oxygen is filtered through filter tank 5 and then enters storage tank 2 through storage inlet pipe 2 19 for storage. The internal pressure of storage tank 2 gradually increases. When the pressure approaches the set upper limit, storage pressure pipe 21 transmits the pressure signal to pressure gauge 22 for real-time display. If the pressure rises further, third valve 25 opens, and return pipe 23 guides some of the gas in storage tank 2 to the three-way connector 16, and then enters pressurization pump 18 through storage inlet pipe 17. Pressurization pump 18 then performs secondary pressurization on the return gas. The gas re-enters the storage tank 2, increasing the gas density inside the tank, preventing overpressure in the storage tank 2 and optimizing storage efficiency. During the recirculation process, the rate gauge 24 monitors the rate of recirculated gas in real time to ensure that the working status of the pressurization pump 18 and the pressure of the storage tank 2 are dynamically balanced. When the gas pressure inside the tank returns to a safe range, the third valve 25 closes, the recirculation process ends, and the storage tank 2 continues normal storage. Throughout the process, the operator can monitor the system status through the pressure gauge 22 and the rate gauge 24 to ensure stable system operation and effectively avoid safety hazards caused by overpressure.
