Abstract
Description
Technical Field
[0001] This utility model relates to the field of desulfurization oxidation suspension fan technology, specifically a noise reduction desulfurization oxidation fan. Background Technology
[0002] More and more power plant desulfurization systems are undergoing energy-saving and efficiency-enhancing retrofits of oxidation blowers. These retrofits often replace oxidation blowers with suspended blowers (air-suspended blowers or magnetic levitation blowers). Suspended blowers are mechanical devices that transport gas. They employ core technologies such as magnetic levitation bearings, three-dimensional flow impellers, high-speed permanent magnet synchronous motors, high-efficiency frequency converters for speed regulation, and intelligent monitoring and control. During startup, the blower levitates before rotating, eliminating friction and the need for lubrication. The three-dimensional flow impeller is directly connected to the rotor, resulting in zero transmission loss. Suspended blowers are high-tech, green, energy-saving, and environmentally friendly products. They utilize contactless, frictionless magnetic levitation bearings and high-speed, high-power permanent magnet synchronous motors to directly drive the high-efficiency fluid impeller, overcoming the shortcomings of traditional blowers and air-suspended blowers. They offer advantages such as high efficiency, low noise, fewer malfunctions, and no need for a lubrication system. Even if the magnetic levitation bearing fails, the system's protective bearings can safely stop the high-speed rotating rotor, preventing serious equipment damage.
[0003] Existing desulfurization oxidation blowers generate significant noise during operation when venting exhaust gas from the pipeline. This noise pollution can reduce the effectiveness of the equipment and damage the pipeline structure.
[0004] Therefore, those skilled in the art have provided a noise-reducing desulfurization oxidation fan to solve the problems mentioned in the background art. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1 to 7 This utility model provides a noise reduction desulfurization oxidation fan, including: a suspended fan body 1, a terminal block 4 below a power circuit breaker 3, a top power communication winding hole 12 at the top of the suspended fan body 1, a bottom power communication winding hole 11 at the bottom of the suspended fan body 1, a touch screen controller 2 installed on the front side of the suspended fan body 1, a discharge cone 8 connected above the suspended fan body 1, a discharge valve 9 connected to one side of the discharge cone 8, a venting silencer 10 for noise reduction installed above the discharge valve 9, a conveying pipe 801 connected above the discharge cone 8, a connecting bolt pipe 804 installed between the conveying pipe 801 and the discharge cone 8, an expansion pipe 802 connected to the end of the conveying pipe 801 away from the discharge cone 8, a sound insulation sleeve 803 sleeved on the outside of the expansion pipe 802, the inner diameter of the conveying pipe 801 being larger than the inner diameter of the expansion pipe 802, and the discharge cone 8 being interconnected through the conveying pipe 801 and the expansion pipe 802;
[0025] Specifically, the expansion tube 802 increases the internal diameter of the delivery tube 801. During the venting and exhaust process, the diameter of the expansion tube 802 helps to prevent air noise when the air is discharged. The air resistance is smaller, and the sound of the air being discharged will be reduced accordingly, thereby assisting the venting silencer 10 and improving the noise reduction effect.
[0026] A power circuit breaker 3 for power safety is installed on the back of the main body 1 of the suspended fan.
[0027] The bottom of the suspended fan body 1 is equipped with a leveling foot 7 for balance adjustment, a coolant pressure gauge 13 is installed on one side of the suspended fan body 1, and a coolant level gauge 14 is installed below the coolant pressure gauge 13.
[0028] Specifically, the bottom of the suspended blower body 1 is equipped with leveling feet 7. By adjusting the leveling feet 7, the suspended blower body 1 is kept in balance. A coolant pressure gauge 13 is used to detect the pressure of the coolant inside the suspended blower body 1 to prevent excessive pressure. At the same time, a coolant level gauge 14 is installed to monitor the coolant usage. The use of coolant accelerates the oxidation rate, effectively reducing the heat generated by the bearings and motor during operation, preventing the lubricating oil from deteriorating due to high temperatures, thereby ensuring stable operation of the equipment and extending its service life. In addition, coolant can also help improve production efficiency. By lowering the operating temperature, it can reduce equipment failures and performance degradation caused by high temperatures, ensuring the smooth progress of the oxidation reaction.
[0029] A rear filter door 6 is installed on the left side of the suspended fan body 1, and a front filter door 5 is installed on the right side of the suspended fan body 1.
[0030] Specifically, a pre-filter is installed inside the front filter door 5 to protect the blower from large particulate impurities, thereby extending the service life of the blower and reducing maintenance needs. By filtering out impurities that may enter the blower, the pre-filter helps maintain the normal operation of the blower and ensures that the oxidation blower can provide stable and efficient oxidation air. The main function of the rear filter door 6 in the oxidation blower is to protect the compressor, pump, instruments and other equipment from damage.
[0031] The working principle of this utility model is as follows:
[0032] When using this utility model, the exhaust cone is connected to the exhaust pipe, and an exhaust valve 9 is installed on the exhaust pipe. When the exhaust valve 9 is opened, the inside of the exhaust pipe is vented. During the venting of the pipe, the venting silencer 10 reduces the noise generated by the venting of the pipe, thus playing a noise reduction role. Secondly, compressed air is sent into the desulfurization tower through the pipe and the exhaust cone 8 to provide oxygen for the desulfurization reaction, forcibly oxidizing calcium sulfite into calcium sulfate, ensuring that the process of absorbing sulfur dioxide continues, improving the desulfurization efficiency, and preventing scale formation in the calcium sulfite and gypsum slurry pipes. The pre-filter inside the pre-filter door 5 filters out impurities that may enter the blower to maintain the normal operation of the blower. At the same time, the post-filter door protects the compressor, pump, instruments and other equipment in the main body 1 of the suspended blower. The coolant inside the main body 1 of the suspended blower can also help improve production efficiency by reducing the operating temperature, reducing equipment failure and performance degradation caused by high temperature, and ensuring the smooth progress of the oxidation reaction.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
