[0002] A plate heat exchanger is a high-efficiency heat exchanger composed of a series of corrugated metal plates stacked together. Thin rectangular channels are formed between the plates, through which heat exchange occurs. Plate heat exchangers are ideal for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss conditions, their heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, their footprint is one-third that of a tubular heat exchanger, and their heat recovery rate can reach over 90%.

[0003] Due to the requirements of condensate water treatment processes for heat users, condensate needs to be cooled. This process can be carried out using plate heat exchangers. However, the heat exchange and cooling effect of ordinary plate heat exchangers is not good. The heat exchange water supply pipeline of the existing plate heat exchangers lacks a pressurization structure, resulting in low heat exchange and cooling efficiency. There is also a lack of safe and stable plate heat exchanger pipeline devices, and the practicality and durability of their pipeline structure need to be improved. At the same time, as disclosed in the utility model patent with announcement number CN210462116U, a plate heat exchanger pipeline includes a main pipe, which is fixedly connected to the input end of a U-shaped pipe. The output end of the U-shaped pipe is fixedly connected to the input end of a tee pipe, and the two output ends of the tee pipe are respectively fixedly connected to the input ends of two conduits. This lacks a pressurization structure, resulting in low heat exchange and cooling efficiency, and the practicality and durability of the pipeline structure also need to be improved.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] This embodiment connects the heat exchange water supply pipeline to the heat exchange water inlet at the cold end of the plate heat exchanger. An external water source can be drawn by a water pump and delivered to the plate heat exchanger for heat exchange and absorption. Simultaneously, a booster pump is installed on the heat exchange water supply pipeline to increase the water pressure, thereby improving the heat exchange efficiency of the plate heat exchanger for the condensate of the heat user and enhancing the cooling effect. The specific implementation method is as follows:

[0029] like Figures 1 to 3 As shown, a plate heat exchanger pressurization pipeline device includes a heat exchange water supply pipeline 2 and a booster pump 7. The heat exchange water supply pipeline 2 is detachably installed at the inlet of the cold end of the plate heat exchanger 1. A water pump 8 is installed at the end of the heat exchange water supply pipeline 2 away from the plate heat exchanger 1. A water supply connector 9 is connected to the input end of the water pump 8. The booster pump 7 for increasing water pressure is installed in the middle of the heat exchange water supply pipeline 2. A water pressure warning component is installed between the booster pump 7 and the plate heat exchanger 1. By connecting the heat exchange water supply pipeline 2 to the heat exchange water inlet at the cold end of the plate heat exchanger 1, external water can be drawn by the water pump 8 and transported to the plate heat exchanger 1 for heat exchange and absorption. At the same time, the booster pump 7 installed on the heat exchange water supply pipeline 2 can increase the water supply pressure and flow rate, and improve the heat exchange efficiency of the plate heat exchanger 1 for the condensate of the heat user, thereby improving the cooling effect.

[0030] The water supply connector 9 is connected to a heat exchange water source, and a connecting flange is provided at the opening of the water supply connector 9. Through the water supply connector 9, cold water for heat exchange can be introduced into the heat exchange water supply pipe 2 and the plate heat exchanger 1.

[0031] The inlet and outlet of the booster pump 7 are both connected to the heat exchange water supply pipe 2 via flanges. A waterproof sealing ring 14 is installed at the connection between the booster pump 7 and the heat exchange water supply pipe 2. The waterproof sealing ring 14 can improve the sealing performance of the connection between the booster pump 7 and the heat exchange water supply pipe 2 and prevent water seepage and leakage.

[0032] A monitoring box 4 is installed on the heat exchange water supply pipeline 2 between the plate heat exchanger 1 and the booster pump 7. The monitoring box 4 is equipped with a water pressure early warning component, which includes a pressure detector 13 and an alarm 5. The alarm 5 is installed on the top of the monitoring box 4, and the pressure detector 13 is located inside the monitoring box 4, with its detection end inside the heat exchange water supply pipeline 2. Through the water pressure early warning component installed on the heat exchange water supply pipeline 2, the water pressure in the pipeline can be monitored via the pressure detector 13. In case of abnormal conditions, the alarm 5 can issue an alarm, facilitating timely handling and maintenance by staff.

[0033] A display 6 is installed in the middle of the monitoring box 4. Both the display 6 and the alarm 5 are electrically connected to the pressure detector 13. The display 6 shows the water pressure in the pipeline. During the water pressure monitoring process, the booster pump 7 can be controlled to increase the water pressure, preventing excessively high or low water pressure from affecting the heat exchange efficiency.

[0034] An electric valve 11 and a safety valve 12 are installed on the heat exchange water supply pipeline 2. The electric valve 11 and the safety valve 12 can be used to control the conduction status of the heat exchange water supply pipeline 2, thereby further improving pipeline safety.

The reinforcing sleeve 15 on the outside of the heat exchange water supply pipe 2 can improve the strength of the pipe, making it less prone to damage and breakage, and improving its pressure resistance. The corrosion-resistant layer 16 on the inside of the heat exchange water supply pipe 2 can improve the corrosion resistance of the pipe and extend its service life.

[0036] The heat exchange water supply pipe 2 is made of stainless steel.

[0037] A filter cartridge 10 is installed between the water pump 8 and the water supply connector 9. The heat exchange water can be filtered through the filter cartridge 10 to prevent excessive impurities from entering the heat exchanger.

[0038] A heat exchange drain pipe 3 is provided at the outlet of the cold end of the plate heat exchanger 1. The heat exchange drain pipe 3 is connected to the heat exchange water supply pipe 2 through the plate heat exchanger 1. The heat exchange drain pipe 3 is coated with a corrosion-resistant coating. After heat exchange and cooling, the cooling water from the heat exchange water supply pipe 2 is discharged through the heat exchange drain pipe 3, thus forming a complete pipe structure.

[0039] Working Principle: The heat exchange water supply pipeline is connected to the heat exchange water inlet at the cold end of the plate heat exchanger. An external water source is drawn by a water pump and delivered to the plate heat exchanger for heat exchange and absorption. Simultaneously, a booster pump is installed on the heat exchange water supply pipeline to increase the water pressure and flow rate, thereby improving the heat exchange efficiency of the plate heat exchanger for the condensate of the heat user and enhancing the cooling effect. A water pressure warning component installed on the heat exchange water supply pipeline allows for monitoring of the pipeline water pressure via a pressure detector. In case of abnormal conditions, an alarm will sound, facilitating timely handling and maintenance by staff. A reinforcing sleeve installed on the outside of the heat exchange water supply pipeline increases the pipeline's strength, making it less prone to damage and breakage, and improving its pressure resistance. A corrosion-resistant layer installed inside the heat exchange water supply pipeline enhances its corrosion resistance and extends its service life.
