Description

Technical Field

[0001] The utility model relates to an environmentally friendly flue gas treatment fluorine plastic steel condenser, belonging to the technical field of condensers. Background Art

[0002] A flue gas condenser is a heat exchanger installed beneath the flue at the tail end of a boiler. Its primary function is to cool the high-temperature exhaust flue gases, thereby recovering heat energy. Using a flue gas condenser can save energy and reduce the environmental impact of flue gas emissions, making it more environmentally friendly. Fluoroplastic steel, a special material made from a combination of fluoroplastic and steel, offers excellent corrosion resistance, high temperature resistance, and insulation properties. It is commonly used in the manufacture of heat exchange equipment to ensure optimal performance.

[0003] During the actual condensation and heat exchange process of the flue gas in the condenser, the flue gas temperature is high, and water droplets usually form on the inner wall of the flue gas duct. When there are a large number of water droplets adhering to the flue gas duct, a water film will be formed, which will reduce the heat exchange efficiency between the condensing medium and the flue gas. In addition, if the water droplets adhere to the inner wall of the flue gas duct for a long time, it will easily cause rust on the inner wall of the flue gas duct, thereby reducing the life and performance of the flue gas duct.

A placing mechanism 7 is provided at the bottom end of the collecting box 12, and the two sides of the placing mechanism 7 are respectively combined with two slots 13. The water droplets on the inner wall of the pipe 1 are scraped off by a number of hanging rings, which can effectively prevent excessive water droplets adhering to the inner wall of the pipe 1 and affect the overall condensation effect. It does not require manual removal, which is more convenient. At the same time, it can also largely avoid the situation where rust occurs inside the pipe 1 due to water droplets, thereby ensuring the life and performance of the pipe 1.

[0023] The scraping mechanism 8 includes a support rod 81, a plurality of baffles 82, a plurality of scraping rings 83 and a groove 84. The support rod 81 is movably inserted into the interior of the pipe 1. The bottom end of the support rod 81 fits in the center position of the upper end of the sealing disk 16. The upper end of the support rod 81 passes through the fixed disk 10. The top of the support rod 81 is provided with a groove 84. The outside of the support rod 81 is fixedly connected to a plurality of baffles 82. The baffles 82 are all tilted. There is space between the baffles 82 and the inner wall of the pipe 1. The bottom ends of the baffles 82 are fixedly connected to the scraping rings 83. The scraping rings 83 fit closely with the inner wall of the pipe 1. When the support rod 81 moves up and down periodically, it drives the baffles 82 and the hanging rings to move up and down, and the water droplets on the inner wall of the pipe 1 are scraped off by the hanging rings. The water droplets pass through the inclined baffles The plate 82 will concentrate the flow onto the sealing disk 16; the pushing mechanism 6 includes a mounting plate 61, a motor 62 and a turntable 63. The mounting plate 61 is fixedly connected to the upper end of the fixed disk 10, and a motor 62 is fixedly connected to one side of the mounting plate 61.

The motor 62 drives the turntable 63 to rotate. Since the turntable 63 is elliptical, the turntable 63 will periodically push the support rod 81; the reset mechanism 9 includes a bottom rod 91, a support block 92, a plurality of connecting rods 93 and a second spring 94. The bottom rod 91 is vertically fixed to the center position of the bottom end of the sealing disk 16, and the support block 92 corresponds to the bottom rod 91.

The second spring 94 is sleeved on the periphery of the bottom rod 91. When the support rod 81 moves down, it will synchronously push the sealing disk 16 down. When the sealing disk 16 moves down, the second spring 94 will be squeezed by the bottom rod 91. Through the cooperation of the second spring 94 and the turntable 63, the support rod 81 can be repeatedly moved up and down, so that the several hanging rings can repeatedly scrape the water droplets on the inner wall of the pipe 1; the placing mechanism 7 includes a recess 71, a support plate 72, a plurality of first springs 73 and a plurality of fixed rods 74. The two sides of the recess 71 are movably inserted in the two slots 13 respectively, and the support plate 72 is located inside the recess 71. When the lock core 71 is unlocked, the lock core 71 is unlocked, and the lock core 71 is unlocked, so that the lock core 71 can be unlocked.An outer ring 17 is fixedly sleeved on the outer side of the upper end of the collection box 12. The upper end of the outer ring 17 is movably sleeved around the outer periphery of the bottom end of the fixed tube 14. The outer ring 17 is tightly fitted with the outer side of the bottom end of the fixed tube 14 to ensure sealing and prevent smoke leakage. The sealing disk 16 is designed as a frustum. The upper edge of the sealing disk 16 is tightly fitted with the bottom end of the sealing ring 15. The diameter of the lower bottom surface of the sealing disk 16 is smaller than the inner diameter of the fixed tube 14. When the sealing disk 16 moves downward, the edge of the sealing disk 16 separates from the sealing ring 15. Water droplets on the sealing disk 16 can flow out through the gap between the outer edge of the sealing disk 16 and the fixed tube 14, and eventually collect in the collection box 12. When the sealing disk 16 and the sealing ring 15 are in contact, they can achieve a sealing effect.

[0024] Specifically, when the present invention is in use, the flue gas enters the interior of the pipe 1 through the smoke inlet 3 and is then discharged from the smoke outlet 4. In this process, the condensing medium in the heat exchange tube 2 exchanges heat with the flue gas, thereby cooling the flue gas. A plurality of inclined baffles 82 are provided in the pipe 1 to extend the flow path of the flue gas in the pipe 1, thereby ensuring the condensation effect of the flue gas. During the condensation process or after the condensation is completed, the motor 62 is started, and the motor 62 drives the turntable 63 to rotate. Since the turntable 63 is elliptical, the turntable 63 will periodically push the support rod 81. When the support rod 81 moves downward, it will drive the baffles 82 and the hanging rings to move downward, and the water droplets on the inner wall of the pipe 1 will be scraped off through the hanging rings. The water droplets will flow to the sealing plate 16 through the inclined baffles 82. When the support rod 81 moves downward, it will synchronously push the sealing plate 16 to move downward. When the sealing plate 16 moves downward, the second spring 94 will be squeezed by the bottom rod 91. Through the cooperation of the second spring 94 and the turntable 63, the support rod 81 can be repeatedly moved up and down, so that the several hanging rings repeatedly scrape the water droplets on the inner wall of the pipe 1. When the sealing plate 16 moves down, the edge of the sealing plate 16 is separated from the sealing ring 15, and the water droplets on the sealing plate 16 can flow out through the gap between the outer edge of the sealing plate 16 and the fixed cylinder 14, and finally be concentrated in the collection box 12; finally, the collection box 12 is pressed down again, and the collection box 12 drives the support plate 72 to move downward to squeeze the several first springs 73. When the outer ring 17 is completely separated from the outer side of the bottom end of the fixed cylinder 14, the recess 71 can be pulled out from the two slots 13, so that the collection box 12 is removed, which can effectively prevent too many water droplets from adhering to the inner wall of the pipe 1 and affecting the overall condensation effect. It does not need to be manually removed, which is more convenient. At the same time, it can also largely avoid the situation where rust occurs inside the pipe 1 due to water droplets, thereby ensuring the life and performance of the pipe 1.
