Description

Technical Field

[0001] This utility model belongs to the technical field of flue gas condensers, specifically relating to a corrugated welded plate flue gas condenser. Background Technology

[0002] Flue gas condensers are key equipment for industrial waste heat recovery and pollutant treatment, and are widely used in industries such as thermal power, metallurgy, and chemical engineering. Traditional shell-and-tube condensers, while possessing high pressure resistance, suffer from low heat exchange efficiency (typically below 2000 W / (m²·K)) and large size (heat exchange area per unit volume less than 100 m² / m³), making it difficult to meet the demands of modern industry for compact and efficient heat exchange equipment.

[0003] In recent years, detachable plate condensers have been developed to enhance heat transfer through the stacking of corrugated plates (the heat transfer coefficient can reach 3000-5000W / (m²·K)).

[0004] The S-wave welded plate flue gas condenser is a type of flue gas condenser, and its operating principle is the same as that of a flue gas condenser.

[0005] However, during the use of the flue gas condenser, a small amount of dust in the flue gas will accumulate inside the condenser's pipes, causing a reduction in the air intake of the condenser's internal pipes or directly causing pipe blockage. Utility Model Content

[0006] Purpose of utility model To address the aforementioned technical problems, this utility model provides a corrugated welded plate flue gas condenser to solve the technical problems mentioned in the background art.

[0007] Technical solution To achieve the above objectives, the present invention provides a corrugated welded plate flue gas condenser, including a condenser mounting structure, a heat dissipation fan on the outer wall of the condenser mounting structure, condenser tube fixing structures on both sides of the inner wall of the condenser mounting structure, and a condenser tube structure between the two condenser tube fixing structures. The condenser tube fixing structure includes a transmission screw and a second connecting pipe. The two ends of the second connecting pipe are provided with third connecting pipes. Positioning strips are provided on both sides of the inner wall of the third connecting pipe. A sealing ring is provided at the connection position of the third connecting pipe and the second connecting pipe.

[0008] Preferably, the condenser mounting structure includes a housing body, with air chambers formed on both sides inside the housing body, and connecting grooves formed on both sides of the outer wall of the housing body, the connecting grooves being connected to the air chambers.

[0009] Preferably, a first connecting pipe is provided on both sides of the inner wall of the housing body, and a first guide groove is provided on both sides of the first connecting pipe.

[0010] Preferably, the transmission screw is rotatably connected to the top and bottom of the inner wall of the housing body, the threads at both ends of the transmission screw have opposite directions, and movable frames are provided at both ends of the two transmission screws. The top and bottom of the movable frames are provided with mating holes, the mating holes are mated with the transmission screws, and the movable frames are connected to the second connecting pipe.

[0011] Preferably, the condenser tube structure includes a connecting ring and a gas tube, a movable strip is provided on one side of the connecting ring, and an electric telescopic rod is rotatably connected between the movable strip and the housing body.

[0012] Preferably, the gas pipe has second guide grooves at both ends, and the second guide grooves are slidably connected to the positioning strip.

[0013] Beneficial effects The technical solution provided by this utility model has the following advantages compared with the prior art: This invention utilizes an outwardly movable condenser tube fixing structure to detach the condenser tube fixing structure from the condenser tube structure, allowing the entire condenser tube structure to move outward. This facilitates the subsequent cleaning of impurities accumulated inside the gas tube, enabling the gas tube to be quickly removed from the condenser and preventing impurities from accumulating inside the gas tube and affecting liquid flow.

[0020] Reference Figure 1-4The diagram illustrates a corrugated welded plate flue gas condenser, comprising a condenser mounting structure 1. A cooling fan 2 is mounted on the outer wall of the condenser mounting structure 1. Condensing pipe fixing structures 3 are located on both sides of the inner wall of the condenser mounting structure 1. A condensing pipe structure 4 is positioned between two of the condensing pipe fixing structures 3. The condenser mounting structure 1 includes a housing body 101. Gas chambers 102 are formed on both sides inside the housing body 101. Connecting grooves 103 are formed on both sides of the outer wall of the housing body 101. 3 is connected to the gas chamber 102. The inner walls of the shell body 101 are provided with first connecting pipes 104 on both sides. The first connecting pipes 104 are provided with first guide grooves 105 on both sides. When the flue gas is condensed, the flue gas enters the interior of the gas chamber 102 and enters the interior of the second connecting pipe 304 through the first connecting pipe 104. Then the flue gas enters the interior of the gas pipe 404 and is discharged through the gas chamber 102 on the other side. The cooling fan 2 rotates, so that the gas flows through the gas pipe 404 to condense the flue gas inside the gas pipe 404. The condenser tube fixing structure 3 includes a drive screw 301 and a second connecting pipe 304. A third connecting pipe 305 is provided at both ends of the second connecting pipe 304. Positioning strips 306 are provided on both sides of the inner wall of the third connecting pipe 305. A sealing ring 307 is provided at the connection point between the third connecting pipe 305 and the second connecting pipe 304. The drive screw 301 is rotatably connected to the top and bottom of the inner wall of the housing body 101. The threads at both ends of the drive screw 301 have opposite directions. Moving frames 302 are provided at both ends of the two drive screws 301. Mating holes 303 are provided at the top and bottom of the moving frames 302. 303 cooperates with the transmission screw 301. The movable frame 302 is connected to the second connecting pipe 304. When it is necessary to clean the impurities remaining in the flue gas inside the gas pipe 404, a motor is provided on one side of the housing body 101. The output end of the motor is connected to the transmission screw 301. Then the motor is started, and the motor drives the transmission screw 301 to rotate. The transmission screw 301 drives the movable frame 302 to move outward. The movable frame 302 drives the second connecting pipe 304 to move outward, so that the second connecting pipe 304 drives the inner third connecting pipe 305 to detach from the condenser pipe structure 4. At the same time, the third connecting pipe 305 moves as a whole towards the inner wall of the first connecting pipe 104.

[0021] Furthermore, in the above technical solution, the condenser tube structure 4 includes a connecting ring 401 and a gas pipe 404. A moving strip 402 is provided on one side of the connecting ring 401. An electric telescopic rod 403 is rotatably connected between the moving strip 402 and the housing body 101. Second guide grooves 405 are provided at both ends of the gas pipe 404. The second guide grooves 405 are slidably connected to the positioning strip 306. When the condenser tube fixing structure 3 is separated from the condenser tube structure 4, the electric telescopic rod 403 is activated. The electric telescopic rod 403 drives the connecting ring 401 to move outward. The connecting ring 401 drives the gas pipe 404 to move outward as a whole. Then, air is blown into the gas pipe 404 by a fan or other means to clean the impurities in the residual flue gas inside the gas pipe 404.

[0022] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
