Description

Technical Field

[0001] This invention relates to the field of clean energy production technology, and in particular to a fully intelligent system for producing hydrogen and oxygen. Background Technology

[0002] In boiler soot blowing and dust removal and related combustion operations in industries such as metal smelting, power generation, and heat production and supply, liquefied petroleum gas (LPG), acetylene, and natural gas are currently the most widely used energy carriers on the market. However, in practical applications, these traditional gases have gradually revealed a series of unavoidable technical defects and application pain points, which not only restrict the improvement of industry production efficiency but also bring significant safety hazards and environmental pressures, becoming a prominent bottleneck for the high-quality development of the industry.

[0003] From a safety perspective, liquefied petroleum gas (LPG), acetylene, and other gases are flammable and explosive substances. Their use requires specialized gas source storage, a process that inherently poses a high safety risk. Leaks or improper operation can easily lead to combustion and explosion accidents, severely threatening the lives and property of personnel and property on the production site. Regarding operational reliability and ash removal capabilities, traditional gas combustion exhibits poor stability, and flame temperature and intensity are difficult to control precisely, resulting in inconsistent ash removal effects. Often, it fails to completely remove ash accumulation from boiler heating surfaces, thus affecting boiler thermal efficiency. Furthermore, the combustion of these gases easily produces carbon deposits and other residues, potentially exacerbating equipment contamination and further reducing operational reliability.

[0004] Traditional gas combustion emits large amounts of harmful gases such as carbon dioxide and sulfides, resulting in high carbon emissions. This not only violates the current development concept of low-carbon and environmental protection but also pollutes the atmosphere. Furthermore, its energy utilization efficiency is extremely low, with a large amount of energy being lost as heat during combustion, leading to serious energy waste and high energy costs for enterprises.

[0005] In terms of equipment operation and maintenance, traditional gas combustion systems rely on large auxiliary equipment, which occupies a large area and has high initial investment costs. The operation process is complicated and requires professional personnel to monitor and control it in real time, which increases labor costs. In addition, the equipment is prone to failure, with frequent and expensive repairs. At the same time, the high-temperature flame and corrosive products generated by combustion can also damage the furnace body, shorten the service life of the equipment, and further increase the operational burden of enterprises.

[0006] Faced with the multiple problems mentioned above, such as significant safety hazards, poor ash removal capacity, environmental pollution, excessive energy consumption, low efficiency, poor reliability, high maintenance costs, damage to the furnace body, and complex operation, the industry urgently needs a new type of energy supply system equipment that can break through the limitations of traditional technology and has the characteristics of being inexpensive, energy-saving, efficient, safe, and environmentally friendly. This is to meet the high-quality energy utilization requirements of modern industrial production and promote the green, safe, and efficient development of related industries.

[0025] The electrolysis reaction device includes a left electrolytic cell 3 and a right electrolytic cell 4; the separation and purification device includes a primary left separation tank 5, a primary right separation tank 6, a filter residue tank 9, and a secondary separation tank 10, with the primary left separation tank 5 and the primary right separation tank 6 interconnected; the material storage device includes a left liquid storage tank 7 and a right liquid storage tank 8, with the left liquid storage tank 7 and the right liquid storage tank 8 interconnected.

[0026] The left electrolytic cell 3 is connected to the primary left separation tank 5, the right electrolytic cell 4 is connected to the primary right separation tank 6, the left storage tank 7 is connected to the primary left separation tank 5 and the primary right separation tank 6 respectively, the right storage tank 8 is connected to the secondary separation tank 10, the right storage tank 8 is connected to the filter residue tank 9 through a circulation and cooling device, and the filter residue tank 9 is connected to the left electrolytic cell 3 and the right electrolytic cell 4 respectively.

[0027] The primary left separator 5 and the primary right separator 6 separate the gas and liquid flowing out of the electrolytic cell; the left and right storage tanks 7 and 8, under the monitoring of the sub-control system 2, replenish pure water in a timely manner to ultimately provide the electrolysis system with a stable concentration of electrolyte; the filter tank 9 filters impurities in the electrolyte to ensure that the electrolyte entering the electrolytic cell is free of impurities, thus ensuring the safe and stable operation of the electrolytic cell; the secondary separator 10 further separates the hydrogen and oxygen from the storage tank into gas and liquid, ensuring the dryness of the gas.

[0028] Furthermore, the circulation and cooling device includes a cooler 11 and a circulation pump 14. The inlet end of the circulation pump 14 is in fluid communication with the right liquid storage tank, and the outlet end is in fluid communication with the liquid inlet end of the cooler 11. The cooler 11 is equipped with a cooling pump 12, and the liquid outlet end of the cooler 11 is connected to the filter residue tank 9. The left liquid storage tank 7 is connected to a replenishment pump 13. The inlet end of the replenishment pump 13 is connected to an external electrolyte storage tank, and the outlet end is in communication with the inside of the left liquid storage tank 7.

[0029] The cooler 11 uses water cooling to control the temperature of the electrolyte within the design range; the cooling pump 12 provides circulating cooling water to the cooler 11; the initial electrolyte injection and the replenishment of pure water during equipment operation are both achieved through the replenishment pump 13; the circulation pump 14 provides power to the electrolyte circulation system.

[0030] Furthermore, the control and management system includes an automatic control system 1 and a sub-control system 2. The automatic control system 1 and the sub-control system 2 are bidirectionally electrically connected. The automatic control system 1 provides electrolysis parameter regulation and safety control for the left electrolytic cell 3 and the right electrolytic cell 4. The sub-control system 2 is used to collect operating parameters such as pressure, temperature, and liquid level, and feed the parameters back to the automatic control system 1 for real-time monitoring to achieve precise control of the equipment and realize intelligent control and unattended operation of hydrogen and oxygen production.

[0031] Furthermore, the control and management system also includes temperature sensors, liquid level sensors, and pressure sensors. There are three temperature sensors used to protect and control the start and stop of the electrolysis power supply and cooling water supply, as well as the equipment.

[0032] Three temperature sensors ( Figure 4 Temperature sensors 1, 2, and 3 are used to monitor the temperature of the electrolyte in the pipeline in real time. Figure 4 Temperature sensor 1 in the middle), electrolyte temperature in the left electrolytic cell 3 ( Figure 4 Temperature sensor 2), electrolyte temperature in right electrolytic cell 4 ( Figure 4 Medium temperature sensor 3); Figure 4 Temperature sensor 1 monitors the solution temperature. When the solution temperature rises to 75°C, cooling pump 12 is started to draw cooling water to cooler 11 to cool the electrolyte. When the temperature drops to 55°C, cooling pump 12 is stopped.

[0033] Figure 4 Temperature sensors 2 and 3 monitor the solution temperature in electrolytic cells 1 and 2. When the solution temperature exceeds 80 degrees Celsius, the electrolysis power supply is turned off, and cooling pump 12 is turned on to cool the solution. Once the temperature drops, the electrolysis power supply automatically restarts. Figure 4 Temperature sensor 2 and temperature sensor 3 are used to protect the electrolysis process and control it to prevent power consumption and gas production (energy saving).

[0034] Figure 4 The liquid level sensor has one pair to monitor the liquid level of the left liquid tank 7 and the right liquid tank 8 in real time. When the liquid level of the left liquid tank 7 and the right liquid tank 8 reaches the set lower limit value of the solution, the replenishment pump 13 is automatically started to replenish the liquid in the storage tank. When the set upper limit of the liquid level is reached, the replenishment pump 13 is automatically turned off.

[0035] Figure 4 The medium pressure sensor is used to monitor the pressure of the produced hydrogen and oxygen in real time. Each sensor is connected to the host RS485 communication signal. When the equipment pressure reaches the set pressure limit, the electrolysis power supply is turned off to stop electrolysis and gas production. When the pressure drops after the gas is used, the electrolysis power supply is automatically turned on to start electrolysis and gas production again.

[0036] The main intelligent control of the host includes: all data is collected by the host and communicated with the Siemens Smart 200 PLC and the rectifier power supply via RS485 to monitor the equipment temperature, liquid level and pressure in real time. The start and stop control of the rectifier is displayed on the MGCS touch screen, which can intuitively monitor the real-time temperature, real-time liquid level and real-time pressure of the equipment, and can control the start and stop of the DC current rectifier of the electrolytic cell according to the real-time pressure.

[0037] Once the pressure is reached, the DC rectifier is shut off. After the hydrogen and oxygen are used (for on-site blasting and ash removal), the pressure drops, and the rectifier power supply starts to regenerate oxygen to ensure the lower pressure limit for the next blast. A flow sensor detects whether there is water in the pipeline to prevent the water pump from running dry and burning out the motor in the absence of water, thus enabling unattended operation of the equipment.

[0038] Furthermore, the structural support components include an electrolytic cell frame 15 and an equipment body frame 16. The left electrolytic cell 3 and the right electrolytic cell 4 are both mounted on the electrolytic cell frame 15, and the equipment body frame 16 provides overall structural support for the entire system.

[0039] Furthermore, both the left electrolytic cell 3 and the right electrolytic cell 4 are equipped with arrayed electrode groups and ion exchange membranes. The top of the left electrolytic cell 3 and the right electrolytic cell 4 are equipped with gas-liquid outlet pipes, which are respectively connected to the primary left separation tank 5 and the primary right separation tank 6.

[0040] Furthermore, the top of the secondary separation tank 10 is equipped with a hydrogen outlet pipe and an oxygen outlet pipe, and each outlet pipe is equipped with a one-way valve and a flow sensor.

[0041] The working principle of this invention is as follows: using ordinary pure water as the basic raw material, adding alkaline electrolyte, and using electricity as power, water is electrolyzed into hydrogen and oxygen; hydrogen and oxygen are used as high-energy fuel gas to replace gases such as acetylene and natural gas for combustion and explosion; the fully intelligent hydrogen and oxygen production system of this invention includes an electrolytic cell, a separation tank, a storage tank, and a filter tank. Under the control of the electrical control system, continuous electrolysis is achieved.
