Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically to an energy-saving and emission-reducing waste heat recovery device. Background Technology

[0002] Flue gas is a major source of energy waste in general energy-consuming equipment. With the continuous development of energy conservation efforts, people are using some equipment to recover waste heat from flue gas in order to achieve the goal of energy conservation and emission reduction. Flue gas waste heat recovery equipment mainly converts the heat carried by flue gas into usable heat through some heat exchange method.

[0003] During the patent application process, a search revealed a Chinese patent with patent number CN220187451U: a waste heat recovery device, comprising: a main body, a support fixedly installed at the lower end of the main body, a flue gas pipe fixedly connected to the upper end of the main body, aluminum fins fixedly connected to the inner surface of the main body, copper pipes fixedly installed on the surface of the aluminum fins, an outlet pipe fixedly connected to the lower end of the main body, an assembly ring fixedly installed on the inner surface of the flue gas pipe, an outer frame provided at the upper end of the assembly ring, and a coarse filter and a fine filter fixedly connected to the inner surface of the outer frame. The outer frame can be installed inside the flue gas pipe using fixing posts and fixing holes. Because the inner side of the outer frame is equipped with multiple filters, when flue gas enters the flue gas pipe, the coarse and fine filters can perform multi-stage filtration of pollutants or impurities in the flue gas, thereby reducing the impurities and pollutants carried by the flue gas inside the main body, reducing the impact on the surfaces of the aluminum fins and copper pipes, and improving the service life of the waste heat recovery device.

[0004] The above solution filters impurities in the flue gas through a filter screen during use, but tiny particles can still enter the main body. These particles will adhere to the surface of the copper tube and form a dust layer, which will lead to a decrease in heat exchange efficiency. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: an energy-saving and emission-reducing waste heat recovery device, comprising: a shell 1, an air inlet pipe 101 and an air outlet pipe 102 respectively provided at the upper and lower ends of the shell 1, a filter assembly 2 provided on the inner wall of the air inlet pipe 101, a copper pipe 3 installed on the inner wall of the shell 1, and the copper pipe 3 is spiral, a dust removal assembly 4 provided inside the shell 1, and a drive assembly 5 provided at the upper end of the shell 1;

[0026] The dust removal assembly 4 includes an outer ring frame 401, an inner ring frame 402, and a traction frame 407. The outer ring frame 401 and the inner ring frame 402 are respectively disposed on the outer and inner side walls of the copper tube 3. Brush plates 403 are installed on the inner wall of the outer ring frame 401 and the outer wall of the inner ring frame 402. Hook 1 404 and hook 2 405 are respectively fixedly connected to the upper ends of the outer ring frame 401 and the inner ring frame 402. A traction rope 406 is connected to the upper end of hook 1 404. The traction frame 407 is fixedly connected to the inner top wall of the outer casing 1. A traction wheel 408 is rotatably connected to the inner wall of the traction frame 407. The end of the traction rope 406 away from hook 1 404 passes through the traction wheel 408 and is connected to hook 2 405. The brush plates 403 in the dust removal assembly 4 remove the accumulated dust on the inner and outer walls of the copper tube 3, preventing the heat exchange efficiency from decreasing due to dust accumulation and extending the service life of the equipment.

[0027] The drive assembly 5 includes a drive base 501 and a drive base 502 fixedly connected to the upper end of the housing 1. A rotating shaft 503 and a rotating shaft 504 are rotatably mounted on the inner walls of drive base 501 and drive base 502, respectively. A guide wheel 505 is fixedly connected to the outer wall of rotating shaft 503, and a winding wheel 506 is fixedly connected to the outer wall of rotating shaft 504. A lifting rope 507 is wound around the outer wall of winding wheel 506. A motor 508, a three-phase AC asynchronous motor capable of forward and reverse rotation, is fixedly connected to one side of drive base 502. The drive assembly 5 controls the lifting and lowering of the outer ring frame 401 and the inner ring frame 402, thereby cleaning the copper pipe 3.

[0028] The upper end of the outer casing 1 has a through hole 103. One end of the lifting rope 507 passes through the winding wheel 506 and the through hole 103 and is fixedly connected to the upper end of the outer ring frame 401. The through hole 103 facilitates the connection between the lifting rope 507 and the outer ring frame 401.

[0029] Four guide rods 6 are fixedly connected to the inner wall of the outer casing 1. The four guide rods 6 pass through the outer ring frame 401 and the inner ring frame 402 respectively and are slidably connected to them. The guide rods 6 improve the stability of the outer ring frame 401 and the inner ring frame 402 during movement and prevent deviation.

[0030] The filter assembly 2 includes a coarse filter 201 and a fine filter 202 disposed on the inner wall of the intake pipe 101, with the coarse filter 201 located above the fine filter 202. The coarse filter 201 removes large particulate impurities first, while the fine filter 202 further intercepts tiny particles.

[0031] The brush plate 403 on the inner wall of the outer ring frame 401 is attached to the outer wall of the copper tube 3, and the brush plate 403 on the outer wall of the inner ring frame 402 is attached to the inner wall of the copper tube 3. By attaching the brush plate 403 to both the outer and inner walls of the copper tube 3, the surface of the copper tube 3 is cleaned, avoiding dust accumulation dead corners.

[0032] Both ends of the copper pipe 3 are provided with connecting pipes 301, and both connecting pipes 301 penetrate the outer shell 1. Water can be injected into the copper pipe 3 through the connecting pipes 301 at both ends to achieve heat exchange with the flue gas inside the outer shell 1.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] In use, an external fan delivers high-temperature flue gas to the inlet pipe 101, which then enters the outer casing 1. At this point, the coarse filter 201 removes large particles, and the fine filter 202 intercepts tiny particles, thus reducing the impurity content in the flue gas. The filtered flue gas then enters the outer casing 1 and exchanges heat with the spiral copper tube 3. The heat from the flue gas is transferred to the medium inside the tube through the copper tube 3, achieving waste heat recovery. When cleaning the copper tube 3, the second motor 508 is started, driving the second shaft 504 to rotate the winding wheel 506, which then winds the gas around the spiral copper tube. The lifting rope 507 on the winding reel 506 pulls the outer ring frame 401 upward along the guide rod 6 via the guide wheel 505. When the outer ring frame 401 moves upward, it scrapes off the dust accumulated on the outer wall of the copper tube 3. In addition, when the outer ring frame 401 rises, the traction rope 406 releases tension through the traction wheel 408, causing the inner ring frame 402 to move downward synchronously. The brush plate 403 on the outer side of the inner ring frame 402 adheres to the inner wall of the copper tube 3 and scrapes off the dust accumulated on the inner wall of the copper tube 3 when it moves downward, thereby ensuring the heat exchange efficiency of the copper tube 3.
