Effectively utilizing waste heat can create greater benefits for enterprises.

[0003] Chinese patent publication number CN220507802U discloses a waste heat recovery device for thermal energy projects. The device includes a thermal frame with an air intake pipe connected to its left side. This technical solution allows dust in the airflow to be filtered by a filter during air intake, keeping the inner wall of the thermal frame clean. This ensures long-term, efficient and stable thermal conductivity, allowing the water inside the water tank to be efficiently and stably heated. To clean the filter, pulling the pull rod and push block to the left significantly increases the amount of heat received by the water tank, enhancing the heating effect of the water inside the tank.

DETAILED DESCRIPTION

[0020] Example 1

[0021] like Figure 1-Figure 5 As shown, an engineering waste heat recovery device proposed in this embodiment includes a heating frame 1, a water storage pipe 8 and an adjusting component. The circumference of the heating frame 1 is connected with an air inlet pipe 2 and an air outlet pipe 3, and a temperature sensor is provided at the air outlet pipe 3 to understand the outflowing gas temperature in real time, so as to avoid the outflowing gas temperature being too high, thereby causing waste of resources. The bottom end of the heating frame 1 is slidingly sealed and provided with multiple guide plates 5; the bottom end of the water storage pipe 8 is sealed and provided on the heating frame 1, and the water storage pipe 8 is connected with a water inlet pipe 9 and a water outlet pipe 10, and the top end of the water storage pipe 8 is sealed and provided with a power generation frame 11, and the power generation frame 11 is provided with a power generation component; the adjusting component is provided on the heating frame 1, and the adjusting component includes a hydraulic cylinder 6 provided at the bottom end of the heating frame 1, an adjusting disk 7 slidably provided inside the heating frame 1, and multiple pairs of sealing plates 19 and elastic plates 20 are provided at the top end of the adjusting disk 7 along a ring, and the output end of the hydraulic cylinder 6 is drivingly connected to the bottom end of the adjusting disk 7.

[0022] The water storage pipe 8 has an adjustment plate portion, which has multiple adjustment channels. The adjustment disk 7 includes a lifting disk portion 71 and multiple adjustment block portions 72 connected in a ring shape on the lifting disk portion 71. The multiple adjustment block portions 72 are respectively located at multiple adjustment channels. Workers control the area of the multiple adjustment block portions 72 extending out of the adjustment plate portion through the hydraulic cylinder 6 to adjust the heating rate of the water flow in the water storage pipe 8.

[0023] When this embodiment is in use, workers send water and hot air to the water storage pipe 8 and the heating rack 1 respectively through the water inlet pipe 9 and the air inlet pipe 2. According to the gas temperature sensed by the temperature sensor, the workers manually adjust the positions of the multiple guide plates 5 to increase the flow distance of the gas in the heating rack 1, so that the heat in the gas can be better dissipated into the water flow in the water storage pipe 8. Then, the hydraulic cylinder 6 drives the regulating disk 7 to rise and fall to adjust the contact area between the water flow and the regulating disk 7 heated by the gas, so as to adjust the heating rate of the water flow, thereby increasing the versatility of the device.

[0024] Example 2

[0025] like Figure 1-Figure 3 As shown, this embodiment proposes a waste heat recovery device for an engineering project. Compared to the first embodiment, the power generation assembly in this embodiment includes a mounting plate 12 mounted on a power generation frame 11, a motor 13 mounted on the mounting plate 12, a collection tank 14 mounted at the bottom end of the mounting plate 12, a rotating rod 17 rotatably mounted on the collection tank 14, a rotating cylinder 18 and a bevel gear b16 coaxially mounted on the rotating rod 17, and a bevel gear a15 connected to the output end of the motor 13. The bevel gear a15 and the bevel gear b16 are meshed. The collection tank 14 has a guide plate portion and a water outlet pipe portion. The guide plate portion gradually slopes downward from one side of the collection tank 14 toward the corresponding side. The water outlet pipe portion is in sliding contact with the water outlet pipe 10.

[0026] When this embodiment is in use, water flows gradually into the water storage pipe 8 through the water inlet pipe 9, and the water level in the water storage pipe 8 gradually rises until the water in the water storage pipe 8 overflows the top of the collection tank 14 and flows into it. The guide plate portion reduces the cross-section of the collection tank 14, thereby increasing the flow rate of the water flow, and the water flow will impact the fan blades of the rotating cylinder 18, thereby driving the rotating cylinder 18 to rotate. The rotating cylinder 18 drives the generator to generate electricity through the rotating rod 17, bevel gear b16, and bevel gear a15, thereby improving the energy recovery rate of the device.
