Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a deoxygenation cyclone membrane device. Background Technology

[0002] Deoxygenation swirl film devices, as a type of highly efficient thermal deoxygenation equipment, are used in boiler feedwater treatment. The working principle of the device is to atomize the water to be deoxygenated into a thin film through a swirl film atomizer, which fully contacts the rising heating steam. The heat of the steam is used to cause the dissolved oxygen in the water to escape rapidly. At the same time, the packing layer in the tower further enhances the gas-liquid separation effect, so that the device can ultimately achieve deep removal of dissolved oxygen in the water, ensuring the safe and stable operation of subsequent equipment. The device has the characteristics of high deoxygenation efficiency and strong load adaptability, and can effectively prevent boilers and pipelines from being damaged by oxygen corrosion.

[0003] However, in actual use, although the deoxygenation swirl film device can make the deoxygenation equipment operate stably and reliably and extend its service life, the steam inside the device enters through the bottom or side. If the opening spacing of the steam distribution pipe is uneven or the pipe diameter is not matched properly, it will lead to uneven distribution of steam in the cylinder. In some areas, there will be excessive steam, which will damage the water film. In other areas, there will be insufficient steam, which will result in insufficient heating of the water film. As a result, the deoxygenation temperature in the water will not reach the required level, and the residual oxygen content will increase. The existing solution is to improve the structure of the steam distribution plate by adopting a regular and evenly distributed steam distribution plate, so that the heating steam rises in an even state and makes better contact with the water film for heating. However, even with a regular and evenly distributed steam distribution plate, in actual operation, due to steam pressure fluctuations and uneven water output from the swirl film tube, there will still be local uneven steam distribution, which will prevent the steam and the swirl film from mixing evenly and affect the deoxygenation efficiency. Utility Model Content

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.

[0035] The steam distribution mechanism 2 includes a steam collecting cylinder 201, which collects steam generated by the heating mechanism 6. The bottom of the steam collecting cylinder 201 is fixedly connected to the bottom of the inner wall of the deaerator 1 on both its front and rear sides. A storage tank 202 is fixedly connected to the rear end of the inner wall of the deaerator 1, and is used to store steam. A one-way valve 203 is fixedly connected to the front of the storage tank 202, allowing steam to enter the storage tank 202 only from the steam collecting cylinder 201. A booster pump 204 is fixedly connected to the top of the storage tank 202, and is used to extract and pressurize the steam in the storage tank 202. A steam delivery pipe 205 is connected to the top of the booster pump 204. The steam pipe 205 is used to transmit pressurized steam. The left end of the steam pipe 205 is fixedly connected to the equalizing shell 206. The equalizing shell 206 can make the steam ejected from each nozzle 209 at the same pressure. The top of the equalizing shell 206 is fixedly connected to the rotating column 207. The top of the inner wall of the deaerator 1 is provided with a rotating groove 208. The rotating column 207 is rotatably connected to the rotating groove 208 to facilitate the rotation of the equalizing shell 206. Multiple nozzles 209 are fixedly connected to the left side of the equalizing shell 206. The nozzles 209 are used to eject steam. The top of the inner wall of the deaerator 1 is provided with a steering assembly 210. The steering assembly 210 is used to adjust the orientation of the nozzles 209.

[0036] The steering assembly 210 includes two mounting blocks 2101 whose tops are fixedly connected to the top of the inner wall of the deaerator tank 1. Electric telescopic rods 2102 are fixedly connected to the left side of the two mounting blocks 2101. Universal joints 2103 are fixedly connected to the left end of the two electric telescopic rods 2102. The electric telescopic rods 2102 and universal joints 2103 ensure that the nozzle 209 is accurately oriented.

[0037] Specifically, after the device is started, the steam generated by heating enters the steam collecting cylinder 201. The steam collecting cylinder 201 collects the dispersed steam and then delivers it to the storage tank 202 through the one-way valve 203. The one-way valve 203 ensures that the steam can only flow in one direction to avoid backflow. The storage tank 202 temporarily stores the steam to maintain the stability of the steam supply. The booster pump 204 is started to extract and pressurize the steam in the storage tank 202, increasing the steam injection pressure. The pressurized steam is delivered to the equalization shell 206 through the steam delivery pipe 205. The cavity design inside the equalization shell 206 ensures that the steam pressure is evenly distributed within the shell, guaranteeing that multiple nozzles 209 receive sufficient steam. Steam at the same pressure is provided by two mounting blocks 2101 fixed to the top of the inner wall of the deaerator 1. The electric telescopic rod 2102 extends and retracts as needed, and drives the equalization shell 206 to rotate through the universal joint 2103. The equalization shell 206 rotates in the rotating groove 208 through the rotating column 207 on the top, realizing the multi-angle adjustment of the nozzle 209. After the adjustment is completed, the nozzle 209 sprays the pressurized steam in a directional manner, which precisely acts on the rotating water film formed by the swirl film tube 4, ensuring that the distribution of steam at different positions is precisely matched with the needs of the water film, avoiding excessive local steam to disperse the water film or insufficient steam, resulting in insufficient heating.

[0038] Reference Figure 6 and Figure 7 The descaling mechanism 5 includes a precision filter screen 501, which is used to remove impurities from the water. The outer wall of the precision filter screen 501 is fixedly connected to the front end of the inner wall of the cyclone membrane tube 4. A vibrator 502 is fixedly connected to the inner wall of the cyclone membrane tube 4. The vibrator 502 can remove stubborn impurities on the precision filter screen 501. A fixing block 503 is fixedly connected to the bottom end of the inner wall of the cyclone membrane tube 4. The fixing block 503 facilitates the fixing of the micro motor 504. The top of the fixing block 503 is fixedly connected to the micro motor 504, which is the precision filter screen. The cleaning of 501 is powered by a micro motor 504 whose output end is fixedly connected to a rotating shaft 505. A spiral blade 506 is fixedly connected to the rear end of the outer wall of the rotating shaft 505. The spiral blade 506 can use the flow of water to make the cleaning brush 507 rotate, saving energy. A cleaning brush 507 is fixedly connected to the front end of the outer wall of the rotating shaft 505. The front end of the precision filter screen 501 is cleaned by the cleaning brush 507. A limit component 508 is provided on the inner wall of the rotating membrane tube 4. The limit component 508 is used to limit the position of the rotating shaft 505.

[0039] The limiting assembly 508 includes two limiting rods 5081. The two limiting rods 5081 are fixedly connected to the inner wall of the rotating film tube 4 on opposite sides. The same limiting ring 5082 is fixedly connected to the adjacent side of the two limiting rods 5081. A limiting groove 5083 is opened on the outer wall of the rotating shaft 505. The limiting ring 5082 is rotatably connected to the limiting groove 5083.

[0040] Specifically, during operation, water first enters the front end of the vortex membrane tube 4 and is filtered by the precision filter screen 501 to remove suspended solids and fine impurities, preventing impurities from entering subsequent channels and causing blockages. When impurities accumulate on the filter screen surface, the vibrator 502 is activated, using high-frequency vibration to remove stubborn impurities from the filter screen surface, preventing filter screen blockage and affecting water flow. Simultaneously, the micro motor 504 on the fixed block 503 drives the rotating shaft 505 to rotate, causing the front-end cleaning brush 507 to rotate synchronously, mechanically cleaning the surface of the precision filter screen 501 and thoroughly removing any remaining impurities after vibration. The spiral blades 506 on the outer wall of the rotating shaft 505 rotate with the shaft, using water flow to enhance the cleaning effect and reduce energy consumption. Furthermore, the spiral blades 506 can also clean the inner wall of the swirl film tube 4 under the drive of the micro motor 504, enhancing the cleaning effect. The limiting component 508, through the limiting rod 5081, fixes the limiting ring 5082, which rotates and cooperates with the limiting groove 5083 on the outer wall of the rotating shaft 505 to limit the radial displacement of the rotating shaft 505, ensuring that the cleaning brush 507 is in close contact with the filter screen and rotates stably, continuously keeping the channel of the swirl film tube 4 unobstructed, and ensuring the normal formation of the water film.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The heating mechanism 6 includes multiple fixed sleeves 601. The fixed sleeves 601 facilitate the attachment of the heating wire 602 and absorb heat, thereby increasing the heating area. The bottom ends of the multiple fixed sleeves 601 are fixedly connected to the bottom of the inner wall of the deaerator 1. Heating wires 602 are fixedly connected to the outer walls of the multiple fixed sleeves 601. The heating wires 602 are the main components for generating steam. The exhaust mechanism 8 includes an exhaust pipe 801, which is used to remove oxygen and separate gas and liquid. The bottom end of the exhaust pipe 801 is fixedly connected to the top end of the connecting pipe 7. A safety valve is fixedly connected to the right end of the outer wall of the connecting pipe 7. 802, safety valve 802 is used to regulate the pressure inside deaerator 1. Two support frames 9 are fixedly connected to the bottom of the outer wall of deaerator 1. The support frames 9 are used to support deaerator 1. Rubber pads 10 are fixedly connected to the bottom of both support frames 9. The rubber pads 10 are used to reduce vibration and avoid damage to the ground. Multiple anti-slip strips 11 are fixedly connected to the bottom of both rubber pads 10. The anti-slip strips 11 are used to increase friction. A water inlet pipe 12 is connected to the left end of deaerator 1. The water inlet pipe 12 is used to introduce water. A sealing ring 13 is fixedly connected to the outer wall of the water inlet pipe 12. The sealing ring 13 can prevent the leakage of clean water or water vapor.

[0042] Specifically, after the device is started, the heating wire 602 supported by the fixed sleeve 601 is energized and heats up. After absorbing heat, the fixed sleeve 601 expands the heating area, uniformly heating the clean water in the deaerator tank 1, accelerating the generation of water vapor, and providing a sufficient steam source for the steam distribution mechanism 2. At the same time, the oxygen released during the deaeration process mixes with the water vapor and enters the exhaust pipe 801 through the connecting pipe 7. The exhaust pipe 801 can achieve gas-liquid separation, allowing the oxygen to be discharged, while the condensate flows back into the tank. When the pressure in the deaerator tank 1 exceeds the set value, the safety valve 802 automatically opens to release pressure, ensuring the safe operation of the equipment. The water inlet pipe 12 is connected to an external water source, and the sealing ring 13 on the outer wall ensures the sealing of the interface to prevent water or steam leakage. The deaerator tank 1 is stably supported by two support frames 9 at the bottom. The rubber pads 10 at the bottom of the support frames 9 buffer the vibration during operation, preventing the equipment from shaking and damaging the ground. The anti-slip strips 11 at the bottom of the rubber pads 10 increase the friction with the ground to prevent the equipment from shifting, ensuring the stable operation of the entire device.

[0043] Working principle: Steam generated by heating in the gas collecting cylinder 201 is collected and transported to the storage tank 202 via the one-way valve 203. The one-way valve 203 prevents steam backflow, and the storage tank 202 maintains the stability of the steam supply to avoid pressure fluctuations during the formation of the swirling film. The booster pump 204 draws steam from the storage tank 202 and pressurizes it to increase the kinetic energy of the steam. The pressurized steam enters the equalization shell 206 through the steam delivery pipe 205. The cavity structure of the equalization shell 206 ensures that the steam pressure is evenly distributed within the shell, ensuring that the multiple nozzles 209 connected to it receive steam from the same pressure source, laying the foundation for uniform spraying. At the same time, the electric telescopic rod 2102 fixed by the mounting block 2101 extends and retracts, and in conjunction with the universal joint 2103, drives the equalization shell 206 to rotate. The equalization shell 206 rotates flexibly in the rotating groove 208 with the help of the top rotating column 207, realizing multi-angle adjustment of the nozzle 209 orientation. Finally, the pressurized steam is directionally ejected through nozzle 209 and precisely applied to the rotating water film. Through stable pressure control and precise angle adjustment, the steam distribution is ensured to match the water film's needs, avoiding problems of local over- or under-steam.

[0044] Furthermore, after the water flows into the swirl tube 4, it first passes through the precision filter 501. The filter's pore size precisely intercepts suspended solids, fine impurities, and some ion crystals in the water, reducing contaminants entering subsequent channels from the source and preventing blockage of the fine structure of the swirl tube 4. When impurities accumulate on the filter surface, the vibrator 502 activates high-frequency vibration, using vibration waves to remove stubbornly attached impurities from the filter surface, preventing clogging of the filter pores. At the same time, the micro motor 504 supported by the fixing block 503 drives the rotating shaft 505 to rotate, causing the front cleaning brush 507 to mechanically clean the filter surface and remove residual impurities from the vibration. The spiral blades 506 on the rotating shaft 505 rotate with the shaft, enhancing the cleaning force with the help of water flow and simultaneously scraping and cleaning the inner wall of the swirl tube 4. In addition, the radial displacement of the shaft is limited by the rotational cooperation between the limiting ring 5082 and the upper limit groove 5083 of the rotating shaft 505, ensuring that the cleaning brush 507 is in close contact with the filter and rotates stably, continuously keeping the channel unobstructed and ensuring normal water film formation and deoxygenation efficiency.
