Description

Technical Field

[0001] The utility model relates to the technical field of water return devices, in particular to a condensate water return device. Background Art

[0002] A condensate return device is a device used to collect and recycle condensate generated in a system. It is mainly used in industrial and commercial fields such as steam systems, air-conditioning systems, and refrigeration equipment. In these systems, water forms water vapor after being heated and evaporated. As heat is lost or conditions change, the water vapor condenses into liquid water. At this time, a condensate return device is needed to collect and process the condensate to achieve the recycling of water resources and the efficient use of energy. Through the condensate return device, the system can recycle and reuse condensate, thereby saving fresh water resources and reducing wastewater discharge. It also helps to improve energy efficiency and reduce energy consumption.

[0003] At present, the existing condensate return device condenses the recovered water vapor into liquid water through the condenser in actual operation. The condenser is usually equipped with a cooling surface inside, which can cool the water vapor by introducing a cooling medium, such as water or air. When the water vapor contacts the cooling surface, the heat will be quickly transferred to the cooling medium, resulting in a rapid drop in the temperature of the water vapor, prompting the water vapor to condense into liquid water.

[0004] However, in the current condensate return unit, there are certain limitations in directly introducing water as a cooling medium to cool water vapor. The flow of cooling water is not targeted, and the cooling water flows over a wide range in the condensate return unit. As supply exceeds demand, cooling water is wasted. When optimizing the design of the condensate return unit, it is necessary to consider how to improve the cooling efficiency and condensate utilization rate to reduce water resource waste and improve the energy efficiency performance of the system.

[0005] Therefore, it is necessary to provide a condensate return device to solve the above technical problems. Utility Model Content

[0031] The output end of the first pump body 5 is fixedly connected to a drain pipe 6, and one end of the drain pipe 6 passes through the inner wall of the bottom of the condenser 2 and extends to below the bottom of the condenser 2. A conduit 15 is fixedly installed at the bottom of the return water storage tank 1, and a valve is provided on the conduit 15.

[0032] A filter cartridge 9 is fixedly mounted on the mounting frame 20, a second pump body 12 is fixedly mounted on the mounting frame 20, and the second pump body 12 is located on one side of the filter cartridge 9, a cover body 13 is provided at the top of the filter cartridge 9, two electric telescopic rods 16 are fixedly mounted on the bottom of the return water storage tank 1, the two electric telescopic rods 16 are respectively located on both sides of the conduit 15, and the driving end of the electric telescopic rod 16 is fixedly connected to the top of the cover body 13, the cover body 13 is slidably sleeved on the outer wall of the conduit 15 through a sealing sleeve fixedly inserted and installed on the top of the cover body 13, a positioning frame 17 is fixedly mounted inside the filter cartridge 9, a high-efficiency filter 18 is provided inside the filter cartridge 9, and the high-efficiency filter 18 is located on the top of the positioning frame 17, positioning rods 19 are fixedly mounted on both sides of the bottom of the cover body 13, an output pipe 10 is fixedly connected between the input end of the second pump body 12 and the lower part of one side of the filter cartridge 9, and a circulation pipe 11 is fixedly connected to the output end of the second pump body 12.

[0033] In one embodiment, the connection between the bottom of the cover body 13 and the top of the filter cartridge 9 is stepped. Through the stepped connection design, a good close contact is formed between the cover body 13 and the filter cartridge 9.

[0034] In one of the preferred embodiments, the condensation tube 7 and the cooling tube 14 are both serpentine in shape, which can greatly increase the surface area of ​​the condensation tube and the cooling tube, and make the contact between the cooling water and the water vapor more complete, thereby improving the cooling efficiency and the utilization rate of the condensed water.

At the same time, the first pump body 5 is started, and the first pump body 5 will pump out the cooling water flowing in the cooling tube 14 at a certain flow rate, and finally output it through the drain pipe 6. Because the cooling tube 14 is directly wrapped around the outside of the condensation tube 7, the cooling water flowing in the water outlet pipe 4 will directly flow along the outside of the condensation tube 7. Flow, during the flow process, the water vapor inside the condenser tube 7 is cooled, so that the water vapor condenses into liquid and finally flows into the inside of the recovery tube 8 through the lower port of the condenser tube 7, and is discharged into the inside of the return water storage tank 1 through the guidance of the recovery tube 8 for temporary storage. The device cools the recovered water vapor by water cooling, and through the setting of the cooling tube 14, the cooling water has a certain flow direction and flow speed to ensure that the cooling water can fully contact and absorb the heat of the water vapor inside the condenser, thereby reducing the temperature of the water vapor and promoting its condensation, and achieving the best cooling effect with the smallest flow range. This optimized design can improve the cooling efficiency and the utilization rate of condensed water, thereby achieving the purpose of saving water resources and improving the energy efficiency of the system.

[0038] The recovered condensate is stored in the return water storage tank 1. When it is needed, the valve on the conduit 15 is opened, and the second pump body 12 is controlled to start working. The passage formed by the output pipe 10, the filter cartridge 9 and the conduit 15 can directly pump out the condensate in the return water storage tank 1 and output it through the circulation pipe 11. The condensate discharged from the circulation pipe 11 can be connected to the upper port of the condensate pipe 7 through a pipeline, so that the unrecovered condensate is cooled by the recovered condensate, so as to achieve the purpose of recycling and further save water resources. The condensate can also be reused for other purposes. In the process of recycling and reusing the condensate, it will be filtered by the high-efficiency filter 18 when passing through the filter cartridge 9, and the condensate is purified to ensure that the recovered water quality meets the use requirements. When the high-efficiency When the filter 18 needs to be replaced after being used for a period of time, the valve on the conduit 15 can be closed, and the electric telescopic rod 16 can be controlled to start working. The driving end of the electric telescopic rod 16 drives the cover body 13 to move vertically, so that the cover body 13 moves upward and loses the sealing effect on the top port of the filter cartridge 9. The positioning rod 19 follows the cover body 13 to move out of the interior of the filter cartridge 9. After the high-efficiency filter 18 located inside the filter cartridge 9 loses the limit of the positioning rod 19, it can be directly taken out from the top opening of the filter cartridge 9 to complete the replacement. Therefore, the detachability of the high-efficiency filter 18 is convenient for users to regularly replace the high-efficiency filter 18 to ensure the filtering effect of the recycled condensate water. At the same time, the detachable structure of the high-efficiency filter 18 is simple and easy to operate, which meets the convenience of user operation and is highly practical.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
