Description

Technical Field

[0001] The utility model relates to the technical field of flue gas condensers, in particular to a flue gas condenser. Background Art

[0002] A flue gas condenser is a heat exchange device used to treat flue gas. It is typically installed in the tail flue of equipment such as boilers and industrial furnaces. Its primary purpose is to recover heat by cooling the flue gas, improving energy efficiency while also lowering exhaust gas temperatures and minimizing thermal pollution to the environment.

The top cover and the bottom cover of this application are connected to the outer tube by screws, and the condensation assembly is connected to the first connecting block by bolts, and the tube plate flange is connected to the upper end cover and the lower end cover by bolts, so that the flue gas condenser is easy to disassemble and clean, and the condensation assembly and the first heat exchange tube are both installed inside the outer tube. This flue gas condenser has a simple structure, small metal consumption, and the condensed liquid can be quickly discharged from the three-way pipe. At the same time, the water flow direction is opposite to the flue gas direction, thereby effectively improving the flue gas condensation effect.

[0029] The present application will be further described in detail below through the accompanying drawings and examples.

[0030] Reference Figures 1 to 4 An embodiment of the present application provides a flue gas condenser, including a flue gas duct 1, a condensation assembly 2 is arranged between two flue gas ducts 1, a moving assembly 3 is arranged at the bottom of the condensation assembly 2, the condensation assembly 2 includes an external tube 21, and a second flange 5 is fixedly installed on the left and right sides of the external tube 21, a first flange 4 is fixedly installed on the side of the condensation assembly 2, a flange bolt 6 is fixedly installed between the first flange 4 and the second flange 5, a gathering bucket 24 is fixedly installed inside the left and right sides of the external tube 21, a split pipe 25 is fixedly installed between the two gathering buckets 24, a water inlet pipe 22 is fixedly installed on the top of the external tube 21, and a water outlet pipe 23 is fixedly installed on the bottom of the external tube 21.

[0031] The gathering bucket 24 communicates with the interior of the flue gas duct 1 on the corresponding side. The branch pipe 25 extends through the interior of the corresponding gathering bucket 24 and communicates with the interior of the flue gas duct 1. The water inlet pipe 22 communicates with the interior of the outer tube 21, and the water outlet pipe 23 communicates with the interior of the outer tube 21. The water inlet pipe 22 is located at the upper left of the outer tube 21, and the water outlet pipe 23 is located at the lower right of the outer tube 21. A heat conducting plate 26 is fixedly mounted between the outer sides of the branch pipe 25. The heat conducting plate 26 has a first connecting hole 27 and a second connecting hole 28 defined therein. The first connecting hole 27 is located between the inner sides of the branch pipe 25, and the second connecting hole 28 is located on the outer side of the branch pipe 25.

[0032] In this embodiment, when the flue gas is condensed, the flue gas is transported to the inside of the outer tube 21 through the flue gas pipe 1. During transportation, the flue gas first passes through the gathering bucket 24. After passing through the gathering bucket 24, the flue gas is diverted through multiple branch pipes 25, and cold water enters through the water inlet pipe 22, flows through the entire interior of the outer tube 21, and is discharged through the water outlet pipe 23. When the cooling water passes through the interior of the outer tube 21, it can take away the heat of the flue gas inside the branch pipe 25, and multiple branch pipes 25 are completely immersed in the cold water. By ensuring that the flue gas inside each branch pipe 25 can fully contact with water, it is ensured that the multiple branch pipes 25 dissipate heat evenly, thereby greatly improving the heat dissipation effect. In addition, by arranging a heat conducting plate 26 inside the branch pipe 25, the heat exchange efficiency between the flue gas and water inside the branch pipe 25 can be accelerated, and the arrangement of the first connecting hole 27 and the second connecting hole 28 ensures the circulation of internal cooling water.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the moving assembly 3 includes a base plate 31. A bracket 33 is fixedly mounted on the top of the base plate 31. The bracket 33 is fixedly mounted on the bottom of the outer tube 21. Universal wheels 32 are fixedly mounted at the four corners of the bottom of the base plate 31. A reinforcement frame 34 is fixedly mounted on the inner side of the bracket 33. Three brackets 33 are fixedly mounted on the top of the base plate 31. All three brackets 33 are fixedly mounted on the bottom of the outer tube 21.

[0034] In this embodiment, dust is likely to remain inside the split pipe 25 when smoke passes through it for a long time. At this time, by loosening the flange bolts 6, the fixation between the first flange 4 and the second flange 5 can be released, so that the entire outer tube 21 can be removed from between the smoke pipes 1 on both sides. After removal, the outer tube 21 is supported by the bracket 33, and the entire outer tube 21 is facilitated to move by the bottom plate 31 and the universal wheel 32. After the outer tube 21 is moved out, high-power wind is blown inward from one side of the outer tube 21, and the dust remaining inside can be blown out by the wind, thereby achieving the purpose of convenient cleaning of the dust remaining inside the split pipe 25.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0036] Working principle: When the flue gas is condensed, the flue gas is transported to the inside of the outer tube 21 through the flue gas pipe 1. During transportation, the flue gas first passes through the gathering bucket 24. After passing through the gathering bucket 24, the flue gas is diverted through multiple branch pipes 25, and cold water enters through the water inlet pipe 22, flows through the entire interior of the outer tube 21, and is discharged through the water outlet pipe 23. When the cooling water passes through the interior of the outer tube 21, it can take away the heat of the flue gas inside the branch pipe 25, and the multiple branch pipes 25 are completely immersed in the cold water. By ensuring that the flue gas inside each branch pipe 25 can fully contact with the water, the heat dissipation of the multiple branch pipes 25 is ensured to be uniform, which greatly improves the heat dissipation effect, and by arranging the heat conducting plate 26 inside the branch pipe 25, the heat dissipation inside the branch pipe 25 can be accelerated. The heat exchange efficiency between flue gas and water is improved, and the setting of the first connecting hole 27 and the second connecting hole 28 ensures the circulation of internal cooling water; dust is likely to remain inside the split pipe 25 when flue gas passes through it for a long time. At this time, by releasing the flange bolts 6, the fixation between the first flange 4 and the second flange 5 can be released, so that the entire outer tube 21 can be removed from between the flue gas pipes 1 on both sides, and after removal, the outer tube 21 is supported by the bracket 33, and the entire outer tube 21 is conveniently moved by the bottom plate 31 and the universal wheel 32. After the outer tube 21 is moved out, it is blown inward from one side of the outer tube 21 by high-power wind force, and the dust remaining inside can be blown out by wind force, thereby achieving the purpose of convenient cleaning of the dust remaining inside the split tube 25.
