Description

Technical Field

[0001] The utility model relates to the technical field of flue gas waste heat recovery devices, and more specifically, to a flue gas waste heat recovery device with a dust removal structure. Background Technique

[0002] A flue gas waste heat recovery device is a waste heat utilization technology used to recover waste heat generated in industrial processes. This waste heat usually comes from waste gas, flue gas, or cooling water, etc., and its temperature is much higher than the ambient temperature. By recovering this waste heat, the energy utilization efficiency can be significantly improved, energy waste can be reduced, and production costs can be lowered. A heat exchanger is an important component in the waste heat recovery process, mainly used to transfer heat from high-temperature flue gas to another medium, such as water or other working fluids. Common types of heat exchangers include shell-and-tube, plate, and finned types, etc. Since the flue gas will carry dust into and adhere to the surface of the heat exchanger when the flue gas waste heat recovery device is working, it is necessary to carry out dust cleaning and removal operations.

[0003] In the related art, during the use of the flue gas waste heat recovery device, generally, workers regularly use cleaning tools to clean and remove the flue gas adhering to the surface of each heat exchanger, so as to carry out maintenance operations.

[0004] However, currently during the use of the flue gas waste heat recovery device, when workers use tools to clean and remove dust from the heat exchanger, they need to clean and remove dust from a single heat exchanger, resulting in a more cumbersome cleaning and dust removal maintenance of the heat exchangers inside the flue gas waste heat recovery device, which affects the convenience and operation efficiency of the cleaning and dust removal maintenance of the flue gas waste heat recovery device.

[0035] Specifically, the working process or principle of the flue gas waste heat recovery device with a dust removal structure is as follows: When in use, hold the cleaning brush rod 6 and enter between the heat pipes 3 inside the waste heat recovery box 1, and make the front side of the cleaning brush rod 6 enter the installation opening 5. At this time, the jack 15 passes through the cleaning brush rod 6 through the jack 15 to conduct preliminary connection work between the cleaning brush rod 6 and the installation opening 5. Then, hold the mounting seat 7 and enter the installation opening 5 to tightly fix the cleaning brush rod 6 and the installation opening 5. And hold the fixing frame 8 to drive the fixing groove 9 to move, so that the fixing seat 10 enters the fixing groove 9 to connect and fix the mounting seat 7 and the cleaning frame 4. At this time, the connecting seat 12 moves in the connecting groove 11 following the fixing frame 8 to conduct moving connection work between the fixing frame 8 and the mounting seat 7. At the same time, the magnetic plate 13 and the magnetic sheet 14 cooperate to conduct magnetic attraction positioning work between the fixing frame 8 and the fixing seat 10 through the connecting seat 12. When it is necessary to clean and remove the soot attached to the surface of the heat pipe 3, first hold the positioning frame 23 and move it to the right to make the positioning frame 23 disengage from the positioning seat 21, and then pull the closing plate 20 forward to open the dust guide hopper 19. And you can hold an external box or tray and move it to the bottom of the dust guide hopper 19 to prepare for subsequent collection of the soot dropped by the cleaning brush rod 6. Then, hold the cleaning frame 4 and drive the cleaning brush rod 6 to move up and down to brush and clean the soot attached to the surface of the heat pipe 3. At this time, the dust guide hopper 19 conducts downward guiding and discharging work on the soot dropped by the cleaning brush rod 6. At the same time, the lifting seat 18 moves in the lifting rail 17 following the cleaning frame 4 to ensure the stability when the cleaning frame 4 drives the cleaning brush rod 6 to clean the soot.

[0036] It should be noted that the waste heat recovery box 1, the air inlet head 2 and the heat pipe 3 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition and principle are clear to those skilled in the art, so no further details will be described.
