Description

Technical Field

[0001] This utility model belongs to the technical field of economizer irregular tube suspension, specifically relating to an economizer irregular tube suspension structure. Background Technology

[0002] An economizer is a device installed at the bottom of the boiler flue to recover the waste heat of the exhaust gas. It heats the boiler feedwater to saturated water at the pressure of the steam drum. Because it absorbs the heat of the high-temperature flue gas, it reduces the exhaust gas temperature, saves energy, and improves efficiency, hence the name economizer. Economizer tubes are an important component of boiler economizers. They are mainly made of seamless steel pipes through bending or folding. Cast iron economizers consist of a series of horizontal cast iron pipes connected to each other at both ends by cast iron elbows and flanges. Steel pipe economizers consist of a series of parallel serpentine tubes. The serpentine tubes are made of seamless steel pipes with an outer diameter of 25-42 mm, and the tubes are usually arranged in a staggered pattern.

[0003] Existing economizer tubes are typically installed in the flue at the tail end of the boiler. Most installations use a hoisting rope to attach the economizer to the inside of the flue. However, the bends in the economizer tubes are usually exposed. During use, the economizer may shake due to the flue gas blowing inside the flue, causing wear and tear on the tubes. In severe cases, this can even lead to deformation, affecting the normal operation of the economizer. At the same time, dust remains on the outer wall of the economizer tube as the flue gas passes through it. Currently, the only way to clean the outer wall is to disassemble the economizer tube, which is inconvenient. Utility Model Content

[0023] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-5The economizer tube suspension structure shown includes an inlet pipe 1, with economizer tubes 2 evenly connected to one side of the inlet pipe 1. Multiple economizer tubes 2 are each connected to an outlet pipe 3 at one end. Connecting plates 4 are connected to both sides of the outer walls of the multiple economizer tubes 2. Fixing rods 5 are evenly connected between the upper and lower parts of two connecting plates 4. First protective plates 6 are connected between two connecting plates 4. The upper ends of the two first protective plates 6 are connected to the lower ends of two of the fixing rods 5, and the lower ends of the two first protective plates 6 are connected to the upper ends of the other two fixing rods 5. A second protective plate 7 is connected between the two fixing rods 5. Protective components are connected to the upper part of one side of each of the two connecting plates 4. These protective components can protect multiple economizer tubes. The tube 2 is connected at both ends. The upper sides of the second protective plate 7 are slidably connected with cleaning components. The middle of one side of each of the two fixed rods 5 is connected with a guide filter plate 18. A collection box 19 is connected between the two guide filter plates 18. The middle of both sides of the collection box 19 is connected to the lower sides of the two guide filter plates 18 through the mounting plate 20. The upper sides of the two connecting plates 4 are connected with hanging rods 21. The upper sides of the two hanging rods 21 are connected with hanging ropes 22. The upper ends of the two hanging ropes 22 and the upper ends of the other two hanging ropes 22 are connected with fixed plates 23. The middle of one side of each of the two fixed plates 23 is connected with a mounting rod 24. One end of the two mounting rods 24 extends through to one side of the two fixed plates 23.

[0025] Two mounting rods 24 are fixed to both sides of the inner wall of the flue. The device can be suspended into the flue through the fixing plate 23, the suspension rope 22 and the suspension rod 21. During the hoisting process, the protective components can protect the bends at both ends of the multiple economizer tubes 2 to avoid collision between the ends of the economizer tubes 2 and the inner wall of the flue. After long-term use, the cleaning components can clean the outer wall of the economizer tubes 2. The cleaned dust falls into the collection box 19 through the guide filter plate 18 to collect the cleaned dust. The two guide filter plates 18 are both set in an inclined shape. The surfaces of the two first protective plates 6 and the second protective plates 7 are evenly provided with multiple air outlets to facilitate the normal passage of flue gas.

[0026] The protective assembly includes a frame 8. Each of the two frames 8 has a buffer spring 9 connected to one side of its inner wall. Several buffer springs 9 are connected to a buffer plate 10 at one end and another buffer spring 9 at the other end. The two buffer plates 10 are slidably connected inside the other frame 8. A support plate 11 is connected to the middle of one side of the two buffer plates 10. One end of the two support plates 11 extends through to one side of the two frames 8. Guide rollers 12 are uniformly rotatably connected to one side of the two support plates 11. Rotation grooves are opened on one side of the support plates 11 corresponding to the multiple guide rollers 12. The multiple guide rollers 12 rotate inside the multiple rotation grooves. The support plate 11 is arranged in an inverted L-shaped structure.

[0027] During installation, the device needs to be hoisted into the flue pipe using hoisting equipment. When the hoisting equipment moves the device to slide on the inner wall of the flue pipe, the buffer spring 9 can buffer the buffer plate 10 and the support plate 11. One side of the two support plates 11 contacts the two sides of the inner wall of the flue pipe, so that the guide roller 12 rotates on the inner wall of the flue pipe. This can ensure the stability of the device during installation and prevent the bends on both sides of the economizer tube 2 from colliding with the inner wall of the flue pipe during installation. After installation, one side of the two support plates 11 contacts the two sides of the inner wall of the flue pipe, which can ensure the stability of the multiple economizer tubes 2 and prevent them from shaking.

[0028] The cleaning assembly includes slide rods 13, with the lower ends of two slide rods 13 extending through to the lower end of the second protective plate 7. The lower ends of the two slide rods 13 are connected to moving rods 14, and the lower ends of moving rods 14 are evenly connected to cleaning plates 15. One side of the multiple cleaning plates 15 contacts multiple points on the outer wall of multiple economizer tubes 2. The lower ends of the multiple cleaning plates 15 are connected to stabilizing rods 16, and the middle of one side of stabilizing rods 16 is connected to a lever 17. One end of lever 17 extends through to one side of one of the first protective plates 6. One side of the multiple cleaning plates 15 is connected to cleaning brushes corresponding to multiple points on the outer wall of multiple economizer tubes 2, and the multiple cleaning brushes contact multiple points on the outer wall of multiple economizer tubes 2.

[0029] The staff manually moves the lever 17 to move the stabilizing rod 16, multiple cleaning plates 15, moving rod 14 and two sliding rods 13. The two sliding rods 13 slide on the upper end of the second protective plate 7. The multiple cleaning plates 15 can brush and clean the outer wall of multiple economizer tubes 2, which is convenient for removing dust from the outer wall of the economizer tubes 2 and avoids dust residue on the outer wall of the economizer tubes 2, which may cause poor preheating effect of the internal water. The cleaned dust enters the collection box 19 through the guide filter plate 18. The cross-sectional shape of the sliding rods 13 is an inverted T-shaped structure. The second protective plate 7 has a groove corresponding to the two sliding rods 13, and the two sliding rods slide in the two grooves respectively.

[0030] Working principle: Two mounting rods 24 are fixed to both sides of the inner wall of the flue. During installation, the device needs to be hoisted into the flue using hoisting equipment. When the device slides on the inner wall of the flue, the guide roller 12 rotates on the inner wall of the flue, ensuring the stability of the device during installation and preventing collisions between the bends on both sides of the economizer tube 2 and the inner wall of the flue during installation. By fixing two fixing plates 23 to the outer walls of the two mounting rods 24 respectively, the hoisting rods 21 can be suspended by the hoisting ropes 22. During installation, one side of each of the two support plates 11 contacts the inner wall of the flue, and the buffer spring 9 can buffer the buffer plate 10 and the support plate 11, allowing the two connecting plates 4, multiple economizer tubes 2, water inlet pipe 1, and water outlet pipe 3 to be installed inside the flue. By connecting the water inlet pipe 1 to the external water pipe and connecting one end of the water outlet pipe 3 to the boiler water inlet, the stability of the device during installation can be improved. During use, by The support plate 11 contacts the inner wall of the flue, ensuring the device is firmly placed inside the flue and preventing the economizer tube 2 from shaking when the flue is venting. When the boiler is working, flue gas enters the flue and comes into contact with multiple economizer tubes 2 through two guide filter plates 18. The guide filter plates 18 can filter some dust. The flue gas can preheat the water inside the economizer tube 2. However, dust will remain on the outer wall of the economizer tube 2 when the flue gas passes through it. After long-term use, the operator can manually move the lever 17 to move the stabilizing rod 16, multiple cleaning plates 15, moving rod 14, and two sliding rods 13. The two sliding rods 13 slide on the upper end of the second protective plate 7. The multiple cleaning plates 15 can brush and clean the outer wall of multiple economizer tubes 2, making it easier to remove dust from the outer wall of the economizer tube 2 and preventing dust from remaining on the outer wall of the economizer tube 2 and causing poor preheating effect of the internal water. The cleaned dust enters the collection box 19 through the guide filter plates 18.
