Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a high-temperature waste gas waste heat utilization treatment device. Background Technology

[0002] Industrial waste gas refers to a mixture of various gases generated during industrial production processes. These gases typically contain air pollutants such as particulate matter, volatile organic compounds (VOCs), sulfur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2), and other greenhouse gases, as well as other harmful chemical substances. The sources of industrial waste gas are widespread, covering almost all industries involving combustion, heating, chemical reactions, or physical processes, such as steel mills, chemical plants, thermal power plants, cement manufacturing, oil refining, and vehicle exhaust.

[0003] In existing waste heat recovery equipment, particulate matter and oily substances in the waste gas often adhere to the inner wall of the heat exchange tube during the waste heat recovery process. Over time, a thick oil layer composed of particulate matter and oily substances gradually accumulates on the inner wall surface of the tube, which is difficult to clean. Furthermore, the presence of the oil layer can affect heat conduction and reduce the efficiency of waste heat recovery.

[0004] Therefore, a high-temperature waste gas waste heat utilization treatment device is needed to solve the above problems. Utility Model Content

[0005] To address the aforementioned problem—namely, to resolve the issue of oily substances and particulate matter adhering to the inner wall of pipes and affecting heat conduction during the waste heat utilization process—this invention provides a high-temperature waste heat utilization treatment device.

[0006] A high-temperature waste gas waste heat utilization treatment device includes a cylindrical body, the cylindrical body including a cylindrical air inlet end, the top end of the air inlet end being connected to an inverted conical cylindrical transition end, the top end of the transition end being connected to a cylindrical air outlet end, a treatment mechanism being rotatably arranged in the cylindrical body, the treatment mechanism including two symmetrically arranged scraper rods, the scraper rods contacting the inner walls of the air inlet end and the transition end, and a heat exchange mechanism being sleeved on the outer circumferential side of the air inlet end.

[0007] Preferably, the processing mechanism further includes a rotating component disposed in the air outlet end. The rotating component includes a mounting bracket fixedly connected in the air outlet end. A rotating shaft is rotatably connected to the mounting bracket. A fan blade is fixedly sleeved on the rotating shaft. The bottom end of the rotating shaft is connected to the two scraping rods through a connector.

[0008] Preferably, the connector includes two rod sleeves arranged from top to bottom, each rod sleeve having two connecting rods symmetrically slidably connected, a spring connecting the two connecting rods, the two connecting rods being fixedly connected to the two scraping rods respectively, a fixing rod being fixedly connected between two adjacent connecting rods, a connecting shaft being fixedly connected between the upper rod sleeve and the rotating shaft, and the end face of the scraping rod near the air inlet being pointed.

[0009] Preferably, an air intake pipe is provided at the lower end of the air intake end, and a receiving mechanism is provided between the air intake pipe and the air intake end. The receiving mechanism includes a motor, and a rotating rod is fixedly connected to the output end of the motor. A replacement disc is symmetrically fixedly connected to both ends of the rotating rod. An annular storage ring is fixedly connected to the inner ring surface of the replacement disc, and the inner ring diameter of the replacement disc is equal to the inner diameter of the air intake end.

[0010] Preferably, the heat exchange mechanism includes a water tank sleeved on the air inlet end, with an inlet pipe connected to one side of the water tank and an outlet pipe connected to the other side of the water tank.

[0011] Preferably, the storage ring includes a ring body, in which an upward-opening receiving groove is formed.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By setting up the air inlet and heat exchange mechanism, the heat exchange mechanism can absorb the waste heat in the high-temperature waste gas after it enters the air inlet, realizing the utilization of the waste heat of the high-temperature waste gas. By setting up the treatment mechanism, the oil layer on the inner wall of the air inlet can be scraped off by the rotation of the scraper rod, avoiding the accumulation of oil layer on the inner wall of the air inlet and affecting the waste heat utilization efficiency.

[0014] 2. By using the rotating component, the flow of exhaust gas can be used to drive the fan blades to rotate, thereby causing the scraper to rotate and scrape the inner wall of the air inlet and transition ends.

[0015] 3. By designing the connecting parts, when the scraper encounters significant resistance during rotation, the scraper can drive the connecting rod into the sleeve, avoiding thicker oil layers or particles. This prevents the scraper from being blocked and unable to scrape the inner wall of the air intake.

[0016] 4. The receiving mechanism can collect the oil layer scraped off by the wiping rod, and the receiving ring can be periodically rotated out by rotating the rod to process the oil layer in the receiving ring and replace it with a new receiving ring. Attached Figure Description

[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0029] like Figure 1 , 2 As shown in Figure 3, this utility model embodiment discloses a high-temperature waste gas waste heat utilization treatment device, including a cylindrical body 1. The cylindrical body 1 includes a cylindrical air inlet end 11. The top end of the air inlet end 11 is connected to an inverted conical cylindrical transition end 12. The top end of the transition end 12 is connected to a cylindrical air outlet end 13. A treatment mechanism 2 is rotatably arranged in the cylindrical body 1. The treatment mechanism 2 includes two symmetrically arranged scraper rods 21. The scraper rods 21 are in contact with the inner walls of the air inlet end 11 and the transition end 12. A heat exchange mechanism 3 is sleeved on the outer circumferential side of the air inlet end 11.

[0030] Specifically, during use, high-temperature exhaust gas enters from the inlet end 11. While in the inlet end 11, the high-temperature exhaust gas transfers heat to the heat exchange mechanism 3 through the heat transfer effect of the inlet end 11, allowing the heat exchange mechanism 3 to absorb the residual heat in the exhaust gas and utilize it. Then, the exhaust gas enters the outlet end 13 through the transition end 12 and is discharged from the outlet end 13. During use, the two scraper rods 21 are rotated, and the two scraper rods 21 move in a circular motion along the inner wall of the inlet end 11 to scrape off the oil layer on the inner wall of the inlet end 11.

[0031] By setting up the air inlet 11 and the heat exchange mechanism 3, after the high-temperature exhaust gas enters the air inlet 11, the heat exchange mechanism 3 can absorb the waste heat in the high-temperature exhaust gas, realizing the utilization of the waste heat of the high-temperature exhaust gas. By setting up the processing mechanism 2, the oil layer on the inner wall of the air inlet 11 can be scraped off by the rotation of the scraper 21, avoiding the accumulation of oil layer on the inner wall of the air inlet 11, which would affect the waste heat utilization efficiency.

[0032] like Figure 3 As shown, the processing mechanism 2 also includes a rotating component 22 disposed in the air outlet 13. The rotating component 22 includes a mounting bracket 221 fixedly connected in the air outlet 13. A rotating shaft 222 is rotatably connected to the mounting bracket 221. A fan blade 223 is fixedly sleeved on the rotating shaft 222. The bottom end of the rotating shaft 222 is connected to the two scraping rods 21 through a connector 23.

[0033] Specifically, during use, when the exhaust gas is discharged from the exhaust end 13, the exhaust gas drives the fan blade 223 to rotate, the fan blade 223 drives the rotating shaft 222 to rotate, and the rotating shaft 222 drives the two scraping rods 21 to rotate through the connecting piece 23. The scraping rods 21 scrape the inner wall of the air inlet end 11 and the transition end 12.

[0034] By using the rotating component 22, the flow of exhaust gas can be used to drive the fan blade 223 to rotate, thereby causing the scraper 21 to rotate and scrape the inner wall of the air inlet 11 and the transition end 12.

[0035] like Figure 3 , 4 As shown in Figure 6, the connector 23 includes two rod sleeves 231 arranged from top to bottom. Each rod sleeve 231 has two connecting rods 232 symmetrically slidably connected. A spring 233 is connected between the two connecting rods 232. The two connecting rods 232 are respectively fixedly connected to the two scraping rods 21. A fixing rod 234 is fixedly connected between two adjacent connecting rods 232. A connecting shaft 235 is fixedly connected between the upper rod sleeve 231 and the rotating shaft 222. The end face of the scraping rod 21 near the air inlet 11 is pointed.

[0036] Specifically, during use, when the rotating shaft 222 rotates, the rotating shaft 222 drives the connecting shaft 235 to rotate, the connecting shaft 235 drives the rod sleeve 231 to rotate, the rod sleeve 231 drives the connecting rod 232 to rotate, and the connecting rod 232 drives the scraper rod 21 to rotate. When the oil layer on the inner wall of the air inlet 11 is thick or there are particles that are difficult to scrape off, the scraper rod 21 can drive the connecting rod 232 into the rod sleeve 231 under the obstruction of the oil layer or particles, and compress the spring 233.

[0037] By setting the connector 23, when the scraper bar 21 encounters greater resistance during rotation, the scraper bar 21 can drive the connecting bar 232 into the bar sleeve 231, avoiding thicker oil layers or particles, and preventing the scraper bar 21 from being blocked and unable to scrape the inner wall of the air inlet 11.

[0038] like Figure 1 , 2 As shown in Figures 3 and 6, an air intake pipe 4 is provided at the lower end of the air intake end 11. A receiving mechanism 5 is provided between the air intake pipe 4 and the air intake end 11. The receiving mechanism 5 includes a motor 51. A rotating rod 52 is fixedly connected to the output end of the motor 51. A replacement disc 53 is symmetrically fixedly connected to both ends of the rotating rod 52. An annular receiving ring 54 is fixedly connected to the inner ring surface of the replacement disc 53. The inner ring diameter of the replacement disc 53 is equal to the inner diameter of the air intake end 11.

[0039] Specifically, during use, high-temperature exhaust gas enters the intake end 11 through the intake pipe 4 and the replacement disc 53. When the scraper 21 scrapes the inner wall of the intake end 11, the oil layer scraped off by the scraper 21 moves downward due to gravity and enters the collection ring 54. After a period of use, the hot air supply of the intake pipe 4 is stopped, and then the motor 51 is started. The output end of the motor 51 drives the rotating rod 52 to rotate 180°, so that another replacement disc 53 rotates between the intake end 11 and the intake pipe 4. Then the collection ring 54 on the replacement disc 53 is processed.

[0040] By setting up the receiving mechanism 5, the oil layer scraped off by the scraper 21 can be collected, and by rotating the rotating rod 52, the receiving ring 54 can be rotated out periodically to process the oil layer in the receiving ring 54 and replace it with a new receiving ring 54.

[0041] like Figure 3 , 6 As shown, the heat exchange mechanism 3 includes a water tank 31 sleeved on the air inlet end 11. A water inlet pipe 32 is connected to one side of the water tank 31, and a water outlet pipe 33 is connected to the other side of the water tank 31.

[0042] Specifically, during use, hot water enters the water tank 31 through the inlet pipe 32 and exchanges heat with the hot air in the air inlet 11. The water after heat exchange is discharged through the outlet pipe 33.

[0043] Furthermore, the storage ring 54 includes a ring body, in which an upward-opening receiving groove is formed.
