Description

Technical Field

[0001] This utility model relates to the field of water source heat pump technology, specifically a waste heat recovery device for water source heat pumps. Background Technology

[0002] Water source heat pumps utilize low-grade heat energy resources formed by absorbing solar and geothermal energy from shallow water sources on the Earth's surface, such as groundwater, rivers, and lakes. Employing the heat pump principle, they transfer low-grade heat energy to high-grade heat energy through a small amount of high-grade electrical energy input.

[0003] The exhaust gas generated during the operation of a water source heat pump mainly includes exhaust gas generated by the compressor and gases such as carbon dioxide generated during heat exchange. Waste heat recovery is generally carried out to treat the exhaust gas. The increase in exhaust gas temperature causes the temperature in the waste heat recovery device to be too high, which causes water to evaporate and easily produces gaseous water. The formation of gaseous water will cause a sudden increase in pressure in the entire water supply system, which will damage the water circulation pipeline and other equipment, and affect the service life of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Example 1:

[0024] Please see Figure 1-4 A waste heat recovery device for a water source heat pump includes a base plate 1, a liquid storage tank 2 fixedly connected to the top of the base plate 1, a fixed cylinder 4 fixedly connected to the top of the liquid storage tank 2, a limiting component 5 installed inside the fixed cylinder 4, a fan component 6 installed inside the fixed cylinder 4 and above the limiting component 5; a filter box 3 fixed to the top of the base plate 1 and located on the right side of the liquid storage tank 2, a filter component 7 installed inside the filter box 3, an inlet pipe 12 fixedly connected to the top of the liquid storage tank 2, a drain pipe 13 fixedly connected to the left end of the liquid storage tank 2, and a recovery pipe 11 fixedly connected to the bottom of the fixed cylinder 4, with the lower end of the recovery pipe 11 extending into the interior of the liquid storage tank 2.

[0025] Furthermore, the limiting component 5 includes a support column 51. The support column 51 is fixedly connected to the bottom of the inner cavity of the fixed cylinder 4. The top of the support column 51 is fixedly connected to a fixed plate 52. The bottom of the fixed plate 52 is fixedly connected to a spring 53. The lower end of the spring 53 is fixedly connected to a limiting block 56. The bottom center of the fixed plate 52 is fixedly connected to a fixing block 54. The inside of the fixing block 54 is fixedly connected to a pressure sensor 55. The trigger point of the pressure sensor 55 is located at the lower end. When the water is heated to the point of excessive steam, the limiting component 5 works. The steam pushes the limiting block 56 upward, and the limiting block 56 pushes the spring 53 back. At the same time, the top of the limiting block 56 contacts the pressure sensor 55, so that the steam can flow into the fixed cylinder 4 and reduce the pressure in the liquid storage tank 2.

[0026] Furthermore, the fan assembly 6 includes a support frame 61. The support frame 61 is fixedly connected inside the fixed cylinder 4 and above the fixed plate 52. A drive motor 62 is fixedly connected to the top center of the support frame 61. The output end of the drive motor 62 extends to the bottom of the support frame 61 and a rotating shaft 63 is fixedly installed thereon. A fan blade 64 is fixedly connected to the rotating shaft 63 near the bottom. The sensor enables the fan assembly 6 to work through the control center. The drive motor 62 drives the fan blade 64 to work, guiding a large amount of water vapor into the fixed cylinder 4. After cooling, the water vapor condenses into water droplets and falls back into the liquid storage tank 2 through the recovery pipe 11, preventing excessive pressure from damaging the equipment.

[0027] Example 2:

[0028] Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: the filter assembly 7 includes a fixing frame 71, the fixing frame 71 is fixedly connected inside the filter box 3, the filter plate 72 is fixedly installed inside the fixing frame 71, the exhaust pipe 73 is fixedly connected to the right end of the filter box 3, the serpentine tube 8 is fixedly connected inside the liquid storage tank 2, the connecting pipe 9 is fixedly connected to the right end of the serpentine tube 8, the right end of the connecting pipe 9 extends into the interior of the filter box 3, the top of the fixing cylinder 4 is fixedly connected to the guide plate 10, the exhaust gas enters the filter box 3 through the connecting pipe 9, part of the exhaust gas that is soluble in water mixes with water, and the rest is discharged after being filtered by the filter plate 72, thus treating the exhaust gas so that it can be directly discharged into the atmosphere, reducing pollution.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] During operation, water is first added to the storage tank 2 through the inlet pipe 12, and water is added to the filter box 3 above the bottom of the fixed frame 71. Air is vented through the serpentine pipe 8, and the water is heated through the principle of heat transfer. The filter assembly 7 is activated, and the exhaust gas enters the filter box 3 through the connecting pipe 9. Some of the water-soluble exhaust gas mixes with the water, and the rest is filtered through the filter plate 72 and discharged. The exhaust gas is treated so that it can be directly discharged into the atmosphere, reducing pollution. When the water is heated to the point of excessive steam, the limiting assembly 5 is activated. The steam pushes the limiting block 56 upward, and the limiting block 56 pushes the spring 53 to retract. At the same time, the top of the limiting block 56 contacts the pressure sensor 55. The sensor, through the control center, activates the fan assembly 6, and the drive motor 62 drives the fan blades 64 to work, guiding a large amount of steam into the fixed cylinder 4. After cooling, the steam condenses into water droplets and falls back into the storage tank 2 through the recovery pipe 11, preventing excessive pressure from damaging the equipment and maintaining the service life of the equipment.
