Abstract
Description
Technical Field
[0001] This utility model relates to the field of water circuit temperature control technology, and more specifically, to a temperature-controlled water circuit system. Background Technology
[0002] Temperature-regulating water circuit systems are mainly used in the field of chemical heat exchange for precise temperature control, energy optimization, and multi-condition temperature regulation. The core components of temperature-regulating water circuit systems typically include heat exchange tanks, heat exchangers, and circulating pumps.
[0003] In existing technology, warm water from the temperature-regulating water tank is pressurized by the temperature-regulating water pump and then cooled in the temperature-regulating water cooler. The cooled water is then used for heat exchange in a certain process. After the heat exchange water is heated, it returns to the temperature-regulating water tank through the return water main. During this process, the system loses some temperature-regulating water, which needs to be continuously replenished. Usually, the steam condensate from the application process can be used for replenishment. However, since the replenishment water is usually transported directly through pipelines, siphoning can occur in the highest-end pipelines of the system. This can lead to some heat exchangers having poor heat exchange performance or even being unable to exchange heat due to insufficient temperature-regulating water. In addition, in existing water circuit systems, the pressure of the temperature-regulating water system needs to be controlled separately by adjusting the amount of nitrogen. This can lead to situations where excessive pressure in pipes, valves, and pumps causes air leakage and liquid leakage.
[0004] Based on the above description, there is an urgent need for a temperature-regulating water circuit system that provides uniform heat exchange, temperature regulation, and stable delivery of warm water. Utility Model Content

[0024] Please see Figures 1 to 4 The present invention provides the following technical solution: a temperature-regulating water circuit system, which is suitable for adjusting the temperature of the hot water after heat exchange in a certain production process.

[0026] In this embodiment, the first heat exchange unit 1 can perform preliminary heat exchange on the hot water after heat exchange, and then the second heat exchange unit 2 can perform sufficient diversion heat exchange to improve the heat exchange effect. Finally, the warm water after heat exchange is sent to the temperature regulating mechanism 4 for further temperature regulation. The top of the temperature regulating mechanism 4 is connected to the water replenishment unit 3 to replenish the water lost by the system, ensure the system pressure, and can also be used to further regulate the water temperature. There is no need to connect nitrogen gas externally to ensure the system pressure, thereby improving the stability of the system and enabling it to be used stably in the production process or circulated back to the first heat exchange unit 1 for heat exchange and temperature regulation again.
[0027] In this embodiment, the first heat exchange unit 1 adopts a plate heat exchanger, the second heat exchange unit 2 includes multiple shell-side or tube-side heat exchangers connected in parallel; the water supply unit 3 includes a water supply tank and a level gauge, which buffers demineralized water; the water return unit 5 includes a water return pipe and a liquid pump installed in the water return pipe, and the discharge end of the temperature control mechanism 4 is connected to the liquid inlet end of the first heat exchanger 1 through the water return pipe.
[0028] Specifically, such as Figure 1 As shown, the drain end of the water replenishment unit 3 is connected to the top of the temperature control mechanism 4; the second heat exchange unit 2 is connected to the top side of the temperature control mechanism 4; the drain pipe is higher than the second heat exchange unit 2.

[0029] In this embodiment, the water supply unit 3 is located at the highest position of the entire system, which can solve the siphon problem of the top pipe and improve the heat exchange efficiency of each heat exchanger and the entire system. In this embodiment, the user unit 6 is the unit that uses temperature-controlled water, such as a heat exchange unit that requires warm water for heat exchange in a certain process.
[0030] Specifically, such as Figure 2 As shown, the temperature control mechanism 4 includes a tank 41, a first inlet pipe 42, and a second inlet pipe 43.

[0033] In this embodiment, the hot water at a higher temperature after use by user unit 6 can also be sent to temperature control mechanism 4. In addition, the hot water after initial heat exchange by first heat exchange unit 1 can also be partially introduced into user unit 6 to mix with the temperature-controlled water for use, which meets the application situation where the temperature adjustment range is not large. At the same time, it can also reduce the heat exchange load of second heat exchange unit 2 and save energy.
