[0020] Compared with the prior art, this utility model provides a system for recovering and utilizing demineralized water, which has the following beneficial effects:

[0021] 1. In this demineralized water recycling system, the electrode cooling water is first rationally replaced to ensure that the quality of the replaced cooling water meets the requirements for subsequent use. During the replacement process, a detection device is used to specifically test the cooling water and monitor key indicators such as conductivity and impurity content in real time. Then, the replaced cooling water is transported to the tank body through the second inlet pipe. The flow rate of the cooling water is then controlled by an electric valve to precisely control the amount of cooling water replenished, ensuring that the liquid level, pressure, and temperature in the tank body are stable at the optimal state. Subsequently, the detection device monitors various parameters in real time throughout the entire recycling process, including but not limited to energy consumption, demineralized water replenishment, and the working status of the tank body. Based on the monitoring data, the technical solution is regularly optimized and adjusted to continuously achieve the goals of energy saving, consumption reduction, and production cost reduction. Through the coordinated use of the detection device, electric valve, first inlet pipe, second inlet pipe, tank body, and outlet pipe, the demand for fresh demineralized water is reduced, thus lowering production costs.

[0022] 2. In this demineralized water recovery system, when the cooling water flows inside the detection pipe and tank body and is detected by the detection device, the water-blocking pad on the outside of the detection plate will contact and squeeze the inner wall of the detection pipe and tank body. Due to the arrangement of the first water-absorbing pad, the second water-absorbing pad, the water-absorbing ball, and the sponge layer inside the water-blocking pad, the cooling water entering the socket will be absorbed first. At the same time, the water-blocking ball outside the support pipe will block the cooling water entering the socket, thereby preventing the cooling water from leaking from the socket and affecting the normal operation of the equipment. The arrangement of the water-blocking pad, the first water-absorbing pad, the second water-absorbing pad, the water-absorbing ball, and the sponge layer enhances the anti-leakage performance of the socket, while the water-blocking ball further enhances the anti-leakage performance of the socket, thereby preventing the cooling water from leaking from the socket and affecting the normal operation of the equipment.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, to reduce the demand for fresh demineralized water and lower production costs, the electrode cooling water in the demineralized water recycling system is first rationally replaced to ensure that the quality of the replaced cooling water meets the requirements for subsequent use. During the replacement process, the cooling water is specifically tested by the detection device 6, which monitors key indicators such as conductivity and impurity content in real time. Then, the replaced cooling water is transported to the tank body 1 through the second inlet pipe 7. The flow rate of the cooling water is then controlled by the electric valve 10 to precisely control the amount of cooling water replenished, ensuring that the liquid level, pressure, and temperature inside the tank body 1 remain stable at the optimal level.

Since the water-blocking pad 23 is equipped with a first water-absorbing pad 22, a second water-absorbing pad 20, a water-absorbing ball 21 and a sponge layer 19, it will first absorb the cooling water entering the socket 8. At the same time, the water-blocking ball 12 on the outside of the support pipe 5 will block the cooling water entering the socket 8, thereby preventing the cooling water from leaking from the socket 8 and affecting the normal operation of the equipment.
