Description

Technical Field

[0001] The present disclosure relates to the technical field of glass tank furnace bubbling, and in particular to a bubbling device and a glass tank furnace. Background Art

[0002] The bubbling technology in glass tank furnaces involves continuously bubbling a portion of the gas through a bubbling device at the bottom of the tank, promoting convection and homogenization of the molten glass through the agitation of the bubbles. Specifically, purified, compressed high-pressure gas is fed into the bubbling device, which continuously releases bubbles of a certain frequency and diameter into the molten glass at a constant pressure through the bubbling tube.

[0003] A bubbling device is installed at the bottom of the tank furnace. Because the head of the bubbler tube is exposed to high-temperature molten glass for a long time, cooling water is required to reduce the impact of high temperature on the bubbler tube head. The bubbler tube head is mostly made of welded stainless steel. Under long-term high-temperature erosion, the weld is prone to cracking, causing cooling water to overflow from the weld and enter the high-temperature molten glass. When a small amount of cooling water overflows from the cracked weld and enters the molten glass, the cooling water vaporizes and produces bubbles upon contact with the high-temperature molten glass. This endothermic vaporization process causes the glass liquid to locally cool at the bubbler tube head, affecting product quality. Furthermore, the bubbles generated by the vaporization of the cooling water are similar to those bubbling from the bubbler tube, making leaks at the bubbler tube head difficult to detect.

[0004] Patent document CN 207944009 U discloses a bubbling system applied to a glass melting furnace, which is provided with a pressure gauge, a pressure switch and a temperature sensor on the water supply branch pipe connected to the water inlet of the water cooling layer, and at the same time, a pressure gauge, a temperature sensor and a flow switch are provided on the return branch pipe connected to the water outlet of the water cooling layer to monitor the water cooling process. However, in actual operation, the pressure in the water cooling channel is low and the cooling water flow rate is slow. This is done to extend the time for cooling water to pass through the water cooling channel, ensure sufficient heat absorption, improve the utilization rate of cooling water, and the cooling water circulation system does not need to use a high-power water pump, saving equipment cost. Therefore, when there is a slight leak in the cooling water at the head of the bubbling tube, on the one hand, the pipeline pressure is low, and on the other hand, the circulating water pump itself can also cause the fluctuation of the water pressure in the circuit, so the pressure change caused by the slight leakage of the head of the bubbling tube is difficult to detect. A flow switch is provided on the return branch pipe to monitor the flow in the circuit. Affected by the fluctuation of the circulating water pump, the flow change caused by the slight leakage of the head of the bubbling tube is also difficult to be monitored. Utility Model Content

It should also be understood that terms defined in, for example, common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined as such herein.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0028] like Figure 1 As shown, the present disclosure provides a bubbling device, including a bubbling tube 1, the bubbling tube 1 is provided with a water cooling jacket 2, the water cooling jacket 2 is connected to a water inlet pipe 201 and a water outlet pipe 202; a first flow meter 401, the first flow meter 401 is arranged on the water inlet pipe 201; a second flow meter 402, the second flow meter 402 is arranged on the water outlet pipe 202; a control element 3, the control element 3 is in communication with the first flow meter 401 and the second flow meter 402 to determine whether the water cooling jacket 2 is leaking based on flow information.

[0029] The water cooling jacket 2 may be a relatively independent structure, and a fluid cavity is formed inside the water cooling jacket 2 for the cooling medium to flow through. Of course, the water cooling jacket 2 and the bubbling tube 1 may also be used to form a fluid cavity.

[0030] During use, the head of the bubbling tube 1 needs to contact the high-temperature glass liquid. The water-cooling jacket 2 surrounds the outer wall of the head of the bubbling tube 1. The cooling water can pass through the fluid cavity inside the water-cooling jacket 2 or the fluid cavity surrounded by the water-cooling jacket 2 and the bubbling tube 1 to reduce the impact of the high-temperature glass liquid on the head of the bubbling tube 1. The first flow meter 401 is used to monitor the cooling water flow entering the fluid cavity, and the second flow meter 402 is used to monitor the cooling water flow discharged from the fluid cavity. Under normal circumstances, there will be a certain amount of water flow loss in the process of cooling water passing through the fluid cavity. The control element 3 can receive the flow information of the first flow meter 401 and the second flow meter 402, and perform difference calculation to monitor the water flow loss generated by the cooling water passing through the fluid cavity in real time. When there is a gap in the water-cooling jacket 2 itself or the junction of the water-cooling jacket 2 and the bubbling tube 1, the cooling water leaks. The water flow loss monitored in real time by the control element 3 will be greater than the normal water flow loss. At this time, the control element 3 determines that there is a cooling water leak and outputs an alarm signal to remind the staff to repair or replace the bubbling device.

[0031] like Figure 1 As shown, in some embodiments, a stop valve 5 is provided on the water inlet pipe 201. The control element 3 can control the opening and closing of the stop valve 5 based on the flow information. When the control element 3 determines that there is a cooling water leak, the control element 3 can adjust the stop valve 5 to a closed state to prevent the cooling water from continuously leaking into the glass tank furnace, thereby reducing the impact of the cooling water leakage on product quality.

[0032] like Figure 1 As shown, in some embodiments, the bubbling device further includes: a first thermometer 403 provided on the water inlet pipe 201 and a second thermometer 404 provided on the water outlet pipe 202 ; the control element 3 communicates with the first thermometer 403 and the second thermometer 404 .

[0033] The first thermometer 403 is used to monitor the temperature of the cooling water when it enters the fluid cavity, and the second thermometer 404 is used to monitor the temperature of the cooling water when it exits the fluid cavity. The control element 3 can receive the temperature information measured by the first thermometer 403 and the second thermometer 404, and perform difference calculations to monitor the temperature changes caused by the cooling water passing through the fluid cavity in real time. When there is a leakage of cooling water, the flow rate of cooling water passing through the fluid cavity per unit time changes, and the temperature change before and after passing through the fluid cavity will also fluctuate. The control element 3 monitors the fluctuation of the temperature change of the cooling water before and after passing through the fluid cavity to assist in determining whether there is a cooling water leakage.

[0034] like Figure 1 As shown, in some embodiments, the bubbling device further includes a gas storage tank 6 and an air inlet pipe 10, one end of the air inlet pipe 10 is connected to the gas storage tank 6, and the other end is connected to the bubbling tube 1, and the bubbling tube 1 can be connected to the bottom 7 of the glass tank kiln.

[0035] Specifically, the high-pressure gas in the gas storage tank 6 enters the bubbling tube 1 through the air inlet pipe 10. The head of the bubbling tube 1 is fixed to the bottom 7 of the glass tank kiln, and can continuously blow bubbles into the high-temperature glass liquid from the bottom 7, effectively controlling, strengthening and improving the convection of the glass liquid in the tank kiln, enhancing the heat exchange and physical and chemical reactions between various materials in the tank, and improving the efficiency of melting, clarification and homogenization during the glass liquid melting process.

[0036] like Figure 1 As shown, in some embodiments, a control valve 8 is provided on the air inlet pipe 10, which can control the gas flow through the air inlet pipe 10. Specifically, the operator can use the control valve 8 to adjust the gas flow entering the glass tank according to different conditions such as the type of glass produced (green glass or white glass), the progress of raw material melting, and the temperature inside the glass tank furnace to achieve a better bubbling effect.

[0037] like Figure 1 As shown, in some embodiments, the control valve 8 is in communication with the control element 3. When the control element 3 detects a cooling water leak, it shuts off the cooling water via the stop valve 5 and simultaneously adjusts the control valve 8 to a closed state, stopping the supply of gas to the tank kiln and facilitating maintenance or replacement of the bubbling device.

[0038] like Figure 1 As shown, in some embodiments, a purifier 9 is further provided on the air inlet pipe 10. Before the high-pressure gas enters the glass liquid through the bubbling tube 1, it needs to be purified by the purifier 9 to remove impurities and moisture in the gas to avoid contamination of the glass liquid during the bubbling process.

[0039] like Figure 1 As shown, in some embodiments, the control element 3 is a PLC controller. PLCs (Programmable Logic Controllers) are used as the control element 3 in the bubbler device due to their advantages such as easy maintenance, strong anti-interference capabilities, and high cost-effectiveness. In other embodiments, the control element 3 may also be a general-purpose processor, a dedicated processor, a digital signal processor (DSP), etc.

[0040] like Figure 1 As shown, in some embodiments, a buffer chamber 101 is provided inside the bubbling tube 1 .

[0041] Normally, the bubbling tube 1 is arranged vertically at the bottom of the glass tank kiln. When the high-pressure gas enters the glass liquid through the bubbling tube 1, the gas will maintain a relatively fast vertical upward speed and quickly pass through the glass liquid, resulting in the bubbles staying in the glass liquid for too short a time, and failing to have a good clarifying and homogenizing effect on the glass liquid. A buffer cavity 101 with an inner diameter larger than the average inner diameter of the bubbling tube 1 is provided in the bubbling tube 1. When the gas passes through the buffer cavity 101, the gas diffuses, rotates and other movements inside the buffer cavity 101, which reduces the speed of the gas entering the glass liquid. The gas passing through the buffer cavity 101 can better separate the batch materials in the kiln, make the quartz particles more comprehensively distributed, and improve the melting efficiency of the tank kiln.

[0042] The present disclosure also provides a glass tank furnace equipped with the aforementioned bubbling device. The bubbling device, mounted at the bottom of the glass tank furnace, monitors leaks in the bubbling device by calculating changes in the flow rate of cooling water flowing through a fluid chamber. Leakage in the bubbling device can be promptly detected, facilitating timely repairs. This reduces the impact of cooling water leakage on the molten glass within the glass tank furnace, effectively improving the production quality of the glass tank furnace.
