[0002] In the glass manufacturing industry, the cooling water system plays a key role to ensure the normal operation of the kiln. Since the electrode brick needs to be cooled while heating the kiln, it is severely consumed and eroded during the heating of the kiln, and the temperature of the kiln cannot be effectively controlled. The discharge port also needs to be cooled by the cooling water in the discharge chute during discharge. The opening of the cooling water must be completely effective and maximum protection of the equipment and stable temperature during the initial heating of the kiln. Without the cooling water system, the temperature fluctuation of the glass melt is relatively large, the good product rate is reduced, the loss rate is increased, and the service life of the kiln is severely reduced.

[0003] At present, the kiln needs to be effectively cooled by the cooling water system during heating. In the cooling process, the blocking phenomenon is prevented, and effective data can be collected in time to adjust the cooling water according to the process, so as to ensure the stable operation of the equipment.

[0004] As described above, the cooling water system in the prior art cannot effectively ensure the cooling effect, which seriously affects the service life of the kiln and reduces the product quality and yield. SUMMARY

[0025] The present application will be further described in detail below in combination with specific examples, which are an explanation of the present application rather than a limitation.

[0026] EMBODIMENT

[0027] As shown in Figure 1 and Figure 2 , a glass kiln cooling water system of the present application comprises a kiln 1, a water circulating device 2, a water rack 3, a thermocouple 4, a flow meter 5, a bypass 6, and an electrode brick 7.

[0028] The water circulating device 2, the kiln 1, and the water rack 3 are arranged in layers; the kiln 1 is arranged in the upper layer; the water rack 3 is arranged in the middle layer; and the water circulating device 2 is arranged in the lower layer.

[0029] The water circulating device 2 is communicated with a water inlet pipe and a water return pipe; the water inlet pipe is communicated with a water inlet on the electrode brick 7 on the kiln 1 to cool the kiln 1; a water outlet on the electrode brick 7 is communicated with the water return pipe; the water return pipe is connected with an instrument branch and a bypass branch; the bypass branch and the instrument branch are both communicated with the water circulating device 2.

[0030] When the glass kiln cooling water system is opened, the bypass branch is opened first, and the instrument branch is closed; then the water inlet pipe is opened; the bypass branch of the water return pipe is circulated to clean the circulating pipeline until it is unobstructed, and then the cooling water is gradually introduced into the instrument branch. The water inlet pipe and the water return pipe are fixed in the middle layer through the water rack 3, and the flow meter 5 and the thermocouple 4 are arranged on the water return pipe.

[0031] This invention discloses a cooling water system for a glass furnace. By incorporating a bypass branch on the return water pipe, blockages are avoided during cooling water operation, preventing inadequate cooling. During startup, all air in the pipes is expelled, ensuring complete cooling and full water flow. This effectively protects instruments during startup and operation, allowing for accurate data measurement and stable production processes. This invention effectively improves process stability and extends the service life of the glass furnace. It also improves product quality and output, effectively reducing the temperature of critical equipment in the furnace and preventing electrode brick corrosion and deformation at high temperatures, which can negatively impact service life and product quality.

[0032] A glass furnace cooling method according to the present invention includes the following processes:

[0033] When turning on the cooling water, turn it on one line at a time. Water enters first and then returns to the circulation system. The return water is processed and enters the water tank and then the main water inlet pipe for circulation. Emergency water is supplied by the tap water system.

[0034] When turning on the cooling water, first open the bypass branch and close the instrument circuit, allowing the bypass branch to circulate and clear all debris from the pipeline until it is unobstructed. Then, gradually introduce water into the instrument circuit. This effectively ensures that the instrument is not easily blocked or malfunctions, and can provide valid measurement data.

[0035] This invention enables the cooling water to be short-circuited and self-circulated on the second floor, ensuring that the cooling water system itself is clean and effectively improving the quality of the cooling water.

[0036] The present invention operates the return water pipe of the water rack as a bypass connection. When the inlet water is opened and the return water is opened one-quarter, the air in the equipment is slowly discharged until it is emptied, and then the return water is fully opened. This process is repeated to open all pipes.

[0037] Observe the quality of the return water to ensure it is clean and free of impurities, then operate the return water pipe of the water rack as a normal pipe, and so on, open all pipes.

[0038] Once the quality of the return water is confirmed to be clean, the corresponding instrument parameters of the return water are collected and adjusted in a timely manner according to the process requirements to ensure that the furnace electrode bricks are effectively cooled, guarantee the normal operation of the equipment, and improve product quality and output.

[0039] The glass kiln production plant in the embodiment is a four-story structure, and the water circulating device 2, the water rack 3 and the kiln 1 are arranged on the second, third and fourth floors of the whole plant respectively; through the layout design of the second, third and fourth floors of the whole plant, an independent, safe and effective cooling water opening operation method is formed. The short-circuit self-circulation of the second floor ensures the quality of the cooling water source, and a series of operations before opening the water rack ensure the water quality of the pipeline and the evacuation of the gas inside the equipment. Finally, the cooling water enters the normal pipeline of the instrument, timely data collection is performed for process adjustment, the cooling effect is improved to ensure the cooling of the equipment, the structural deformation caused by the excessively high temperature of the equipment is reduced to cause the quality of the kiln to decrease, the kiln and product quality are affected, and the service life and stability of the kiln are improved.

[0040] The glass kiln cooling method of the embodiment can effectively protect the equipment and stabilize the temperature in the initial heating period, the cooling water opening operation method effectively controls the temperature fluctuation of each equipment itself, and ensures the stability of the kiln and operation.
