Description

Technical Field

[0001] This utility model relates to the technical field of boiler degassing, and in particular to a degassing component and its electrode boiler. Background Technology

[0002] In the fields of industrial production and energy supply, electrode boilers, as a highly efficient and environmentally friendly heating device, are being used more and more widely. Electrode boilers heat water directly with electricity, and have advantages such as high thermal efficiency, rapid start-up, and flexible adjustment. They are particularly suitable for scenarios with high environmental protection requirements and sufficient power resources, such as areas with strict carbon emission restrictions, distributed energy systems, and industrial sites that require rapid response to changes in heat load.

[0003] However, during the operation of electrode boilers, a certain amount of gases inevitably dissolve in the boiler water. These dissolved gases mainly include oxygen and carbon dioxide. The presence of these gases in the boiler water has many adverse effects on the boiler system. For example, oxygen is one of the main factors causing corrosion of boiler metal components. When oxygen in the boiler water comes into contact with metal surfaces, an electrochemical corrosion reaction occurs, gradually eroding the boiler's heating surfaces, pipes, and other metal components, shortening the boiler's service life, increasing equipment maintenance and replacement costs, and in severe cases, even causing safety accidents and threatening production safety. The presence of carbon dioxide also increases the acidity of the boiler water, further exacerbating corrosion of metal components. It also affects the heat transfer performance of the boiler water, reducing the boiler's thermal efficiency and increasing energy consumption. Therefore, there is an urgent need for a degassing component and its electrode boiler. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this utility model provides a degassing component and its electrode boiler.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses a degassing component and its electrode boiler, comprising:

[0007] The degassing vessel is supported on the ground. The degassing vessel has a degassing chamber inside and an outlet connected to the top of the degassing vessel.

[0008] The filtration mechanism is connected to the gas outlet of the degassing vessel and filters the gas.

[0009] The degassing vessel includes:

[0010] A heating cylinder is installed inside the degassing vessel. Multiple connecting rods are arranged circumferentially on the outer wall of the heating cylinder, and the heating cylinder is fixedly installed inside the degassing vessel through the connecting rods.

[0011] The water pump is fixedly installed on the outer wall of the degassing vessel. The water pump input end is used to draw in boiler water, and the water pump output end is connected to a water delivery pipe.

[0012] An annular nozzle is installed inside the degassing vessel and is connected to a water supply pipe. Multiple water nozzles are arranged in a ring on the inner wall of the annular nozzle, and each water nozzle is located at the top of the heating cylinder.

[0013] Furthermore, the degassing vessel also includes:

[0014] The rotating shaft is hoisted and rotated at the top of the degassing reactor;

[0015] A water-driven turntable is fastened to a rotating shaft. Multiple water tanks are arranged in a circular pattern on the water-driven turntable, and the output ends of each water nozzle face the water tanks of the water-driven turntable.

[0016] Multiple stirring rods are provided, and multiple rotating shafts are provided on the outer wall of the rotating shaft. Each rotating shaft is arranged in a circular motion in the heating cylinder.

[0017] Furthermore, a guide plate is fixedly mounted on the rotating shaft. The guide plate is umbrella-shaped and positioned below the water-drive turntable.

[0018] Furthermore, a drain pipe is connected to the bottom of the heating cylinder, and the output end of the drain pipe is located outside the degassing vessel. A valve is installed on the drain pipe.

[0019] Furthermore, a waste discharge pipe is connected to the bottom of the degassing vessel.

[0020] Furthermore, the filtration mechanism includes:

[0021] The exhaust pipe is connected to the outlet of the degassing reactor;

[0022] The filter box is supported on the ground. The filter box is equipped with an inlet chamber, a treatment chamber and an exhaust chamber. The inlet chamber is connected to the treatment chamber, the treatment chamber is connected to the exhaust chamber and the exhaust chamber is connected to the discharge port.

[0023] The suction fan is installed inside the inlet cavity and connected to the outlet end of the exhaust pipe;

[0024] Two filter elements are installed in the processing chamber to filter the gas drawn in by the suction fan.

[0025] Furthermore, a slag-receiving hopper is slidably inserted into the processing chamber and positioned below the filter element to collect the dust and ash that falls off the filter element.

[0026] In the above technical solution, the degassing component and its electrode boiler provided by this utility model have the following beneficial effects:

[0027] By spraying boiler water into the top of the heating cylinder in the form of mist or fine droplets, the boiler water and the heat generated by the heating cylinder are in full contact, greatly increasing the heating area and heating speed of the boiler water. This accelerates the release of dissolved gases in the boiler water, thereby improving degassing efficiency and effectively reducing the content of gases such as oxygen and carbon dioxide in the boiler water, thus reducing the corrosion of boiler metal components. The reduced content of corrosive gases in the boiler water lowers the probability of electrochemical corrosion reactions on boiler metal components, slowing down the erosion rate and extending the boiler's service life. This reduces the frequency of equipment maintenance and replacement, lowering maintenance and replacement costs. The release of gases such as carbon dioxide reduces the acidity of the boiler water, reducing corrosion of metal components, and improves the heat transfer performance of the boiler water, allowing heat to be transferred more effectively from the heating cylinder to the boiler water, improving boiler thermal efficiency, reducing energy consumption, and meeting energy conservation and emission reduction requirements. The filtration mechanism filters the gas discharged from the degassing vessel, removing impurities or harmful components, making the emitted gas more environmentally friendly and reducing environmental pollution.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] See Figure 1-4 As shown;

[0036] A degassing assembly and its electrode boiler according to an embodiment of this utility model include:

[0037] Degassing vessel 1 is supported on the ground. Degassing vessel 1 has a degassing chamber inside and an outlet connected to the top of degassing vessel 1.

[0038] The filtration mechanism is connected to the gas outlet of the degassing vessel 1 and filters the gas.

[0039] The degassing vessel 1 includes:

[0040] A heating cylinder 11 is installed inside the degassing vessel 1. Multiple connecting rods are arranged circumferentially on the outer wall of the heating cylinder 11. The heating cylinder 11 is fixedly installed inside the degassing vessel 1 through the connecting rods.

[0041] Water pump 12 is fixedly installed on the outer wall of degassing vessel 1. The input end of water pump 12 is used to draw in boiler water, and the output end of water pump 12 is connected to a water supply pipe 13.

[0042] An annular nozzle 14 is installed inside the degassing vessel 1. The annular nozzle 14 is connected to the water supply pipe 13. Multiple water nozzles 15 are annularly connected on the inner wall of the annular nozzle 14. Each water nozzle 15 is installed on the top of the heating cylinder 11.

[0043] By adopting the above technical solution, the water pump 12 is fixedly installed on the outer wall of the degassing vessel 1. Its input end is used to draw in boiler water. After being pressurized by the water pump 12, the drawn-in boiler water is transported from the output end to the annular spray pipe 14 through the water supply pipe 13. The annular spray pipe 14 is located inside the degassing vessel 1 and is connected to the water supply pipe 13. Multiple water nozzles 15 are arranged in a ring on its inner wall, and each water nozzle 15 is located at the top of the heating cylinder 11. After the boiler water enters the annular spray pipe 14, it is sprayed onto the top of the heating cylinder 11 in the form of mist or fine water droplets through each water nozzle 15. In the degassing tank 1, a heating cylinder 11 is installed inside the degassing tank 1. When powered on, it generates heat to heat the sprayed boiler water. As the boiler water is heated, dissolved gases such as oxygen and carbon dioxide gradually precipitate due to decreased solubility. The precipitated gases rise with the water vapor, reaching the top of the degassing tank 1, and are discharged through the connected outlet. A filtration mechanism connected to the outlet of the degassing tank 1 filters the discharged gas, removing impurities or harmful components to make the emitted gas more compliant with environmental protection requirements. The boiler water is then sprayed in a mist or fine spray. Water droplets are sprayed onto the top of the heating cylinder 11, ensuring full contact between the boiler water and the heat generated by the heating cylinder 11. This significantly increases the heating area and heating speed of the boiler water, accelerating the release of dissolved gases and thus improving degassing efficiency. It effectively reduces the content of oxygen, carbon dioxide, and other gases in the boiler water, minimizing corrosion of boiler metal components. The reduced content of corrosive gases in the boiler water lowers the probability of electrochemical corrosion reactions on the boiler metal components, slowing down the erosion rate and extending the boiler's service life. This reduces the frequency and cost of equipment maintenance and replacement. The release of carbon dioxide and other gases reduces the acidity of the boiler water, decreasing corrosion of metal components. Simultaneously, it improves the heat transfer performance of the boiler water, allowing heat to be transferred more effectively from the heating cylinder 11 to the boiler water, increasing the boiler's thermal efficiency, reducing energy consumption, and meeting energy conservation and emission reduction requirements. The filtration mechanism filters the gas discharged from the degassing vessel 1, removing impurities or harmful components, making the emitted gas more environmentally friendly and reducing pollution.

[0044] As a preferred embodiment of the above technical solution, such as Figures 1 to 3 As shown, the degassing vessel 1 also includes:

[0045] Rotating shaft 16 is hoisted and rotated at the top of the inside of the degassing vessel 1;

[0046] The water-driven turntable 17 is fastened to the rotating shaft 16. Multiple water tanks are arranged in a circular pattern on the water-driven turntable 17, and the output ends of each water nozzle 15 face the water tanks of the water-driven turntable 17.

[0047] Multiple stirring rods 18 are provided on the outer wall of the rotating shaft 16, and each rotating shaft 16 is arranged in the heating cylinder 11 for circumferential rotation.

[0048] In this embodiment, the water pump 12 draws in boiler water and delivers it to the annular nozzle 14 through the water supply pipe 13. Multiple nozzles 15 on the inner wall of the annular nozzle 14 spray the boiler water at a certain speed, with the output ends of each nozzle 15 facing the water tank on the water-driven turntable 17. When the high-speed water flow impacts the water tank on the water-driven turntable 17, it exerts a force on the water tank. Since the water-driven turntable 17 is securely mounted on the rotating shaft 16, according to the principle of force transmission, this force will cause the water-driven turntable 17 and the rotating shaft 16 to rotate together. Multiple stirring rods 18 are arranged on the outer wall of the rotating shaft 16, and each stirring rod 18 is circumferentially rotated within the heating cylinder 11. As the rotating shaft 16 rotates, the stirring rods 18 also rotate, stirring the boiler water within the heating cylinder 11. Under the heating action of the heating cylinder 11, the boiler water temperature rises, and the dissolved oxygen in the water... Gases such as carbon dioxide gradually precipitate due to decreased solubility. The precipitated gases rise with water vapor to the top of the degassing vessel 1, are discharged through the connected outlet, and then enter the filtration mechanism for filtration. The stirring rod 18 stirs the boiler water in the heating cylinder 11, causing the boiler water to tumble continuously during the heating process. This increases the contact area and contact time between the water and the heating cylinder 11, while breaking the temperature and concentration gradients within the water body. This allows heat to be transferred to the water more evenly, accelerating the precipitation of gases dissolved in the boiler water and improving degassing efficiency. The stirring action of the stirring rod 18 causes convection in the boiler water within the heating cylinder 11, allowing the heat generated by the heating cylinder 11 to be transferred to the boiler water more evenly. This avoids local overheating or undercooling, improves heat exchange efficiency, and enables the boiler water to reach the required temperature more quickly.

[0049] As a preferred embodiment of the above technical solution, such as Figure 3 As shown, a guide plate 19 is fixedly mounted on the rotating shaft 16. The guide plate 19 is umbrella-shaped and is located below the water drive turntable 17.

[0050] In this embodiment, during the rotation of the umbrella-shaped guide plate 19, the shearing effect of its edge can break the liquid film between the gas and the boiler water, reduce the residence time of the gas in the boiler water, and make it easier for the gas to escape from the water, thereby improving the efficiency of gas-liquid separation. The guiding effect of the guide plate 19 on the falling boiler water can prevent the boiler water from forming turbulence during the descent and carrying the rising gas, further ensuring the effect of gas-liquid separation, reducing the amount of water vapor in the discharged gas, and improving the purity of the gas. The guide plate 19 disperses the falling boiler water more evenly in the heating cylinder 11, making the contact area between the boiler water and the heating cylinder 11 larger and more sufficient, thereby improving the heat transfer efficiency and enabling the boiler water to be heated faster.

[0051] As a preferred embodiment of the above technical solution, a drain pipe 1a is connected to the bottom end of the heating cylinder 11, the output end of the drain pipe 1a is located outside the degassing vessel 1, and a valve is provided on the drain pipe 1a.

[0052] In this embodiment, the degassed boiler water is discharged in a timely manner through the drain pipe 1a, which avoids the degassed boiler water from staying in the heating cylinder 11 for a long time and dissolving the gas again, thus ensuring the stability of the degassed effect. At the same time, it prevents the boiler water from being repeatedly heated in the heating cylinder 11, which would lead to water quality deterioration, and ensures that the boiler water entering the subsequent system has good water quality. The drainage process helps to maintain the dynamic balance of the boiler water in the degassed vessel 1, so that new boiler water can continuously enter the heating cylinder 11 for degassed treatment, ensuring the continuity and efficiency of the entire degassed process.

[0053] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, a waste discharge pipe 1b is connected to the bottom end of the degassing vessel 1;

[0054] In this embodiment, during the operation of the electrode boiler, the water pump 12 draws in boiler water, which is then transported to the annular nozzle 14 via the water supply pipe 13 and sprayed out through multiple spray nozzles 15. The sprayed boiler water inevitably splashes directly into the degassing vessel 1 and accumulates at the bottom of the degassing vessel 1. The waste discharge pipe 1b can discharge the wastewater in a timely manner and extend the service life of the equipment.

[0055] As a preferred embodiment of the above technical solution, such as Figure 1 and Figure 4 As shown, the filtration mechanism includes:

[0056] The exhaust pipe 21 is connected to the exhaust port of the degassing vessel 1;

[0057] The filter box 22 is supported on the ground. The filter box 22 is provided with an inlet chamber, a treatment chamber and an exhaust chamber. The inlet chamber is connected to the treatment chamber and the treatment chamber is connected to the exhaust chamber. The exhaust chamber is connected to an outlet 25.

[0058] The suction fan 23 is installed inside the inlet cavity and is connected to the output end of the exhaust pipe 21;

[0059] Two filter elements 24 are installed in the processing chamber to filter the gas drawn in by the suction fan 23.

[0060] In this embodiment, during the operation of the electrode boiler, the boiler water is heated by the heating cylinder 11 in the degassing vessel 1. Dissolved gases such as oxygen and carbon dioxide are released and rise to the top of the degassing vessel 1 along with water vapor. These gases enter the exhaust pipe 21 through the outlet at the top of the degassing vessel 1. The exhaust pipe 21 transports the gas to the inlet chamber of the filter mechanism. The suction fan 23, located inside the inlet chamber, starts working, generating negative pressure to draw the gas from the exhaust pipe 21 into the inlet chamber, allowing the gas to smoothly enter the filter box 22 for subsequent processing. The drawn-in gas enters the processing chamber from the inlet chamber, where two filter elements 24 are installed. When the gas passes through the two filter elements 24, impurities and particulate matter are trapped by the filter elements 24, thereby achieving… The gas is now purified; after filtration, the gas enters the exhaust chamber from the treatment chamber and is finally discharged into the atmosphere through the exhaust port 25 connected to the exhaust chamber. The two filter elements 24 can effectively filter impurities and particulate matter in the gas, reducing the pollution caused by these pollutants being directly emitted into the atmosphere, meeting increasingly stringent environmental protection requirements, helping to improve air quality and protect the ecological environment. The gas discharged from the degassing vessel 1 may contain some corrosive substances or particulate matter. If it is discharged directly or enters other equipment without filtration, it may cause corrosion or blockage damage to subsequent equipment. The filtration mechanism removes these harmful substances through filtration, protecting the safe operation of subsequent equipment and extending the service life of the equipment.

[0061] As a preferred embodiment of the above technical solution, such as Figure 4 As shown, a slag receiving hopper 26 is slidably inserted in the processing chamber. The slag receiving hopper 26 is located below the filter element 24 and is used to collect the dust and ash shaken off by the filter element 24.

[0062] In this embodiment, the slag receiving hopper 26 is installed in the processing chamber using a sliding insertion method. Operators can easily pull out the slag receiving hopper 26 for cleaning without large-scale disassembly of the filter mechanism, greatly simplifying the cleaning process and saving maintenance time and labor costs. Compared to the case without the slag receiving hopper 26, operators do not need to clean dust in the complex environment inside the processing chamber, reducing maintenance difficulty and improving the safety and reliability of maintenance work. The slag receiving hopper 26 can promptly collect the dust shaken off from the filter element 24, preventing dust accumulation in the processing chamber and thus preventing dust from being carried back by the gas, causing secondary pollution. This ensures the filtration effect of the filter mechanism on the gas, making the emitted gas cleaner. Timely cleaning of the dust shaken off from the filter element 24 can reduce the clogging and covering of the filter element 24, maintain the filtration performance and air permeability of the filter element 24, extend the service life of the filter element 24, and reduce equipment operating costs.

[0063] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
