[0028] The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the technologies, methods and equipment should be regarded as part of the specification. As mentioned in the above background technology, during the production process of the glass kiln, sulfur dioxide gas with a certain temperature is usually discharged into the bottom of the slag box of the glass kiln to form a protective film to ensure the processing quality of the glass. For this reason, the sulfur dioxide gas needs to be heated before being discharged into the bottom of the slag box. In production, it is often necessary to purchase canned sulfur dioxide. If the canned sulfur dioxide is directly discharged into the bottom of the slag box, the quality of the glass will inevitably be affected due to the low temperature of the canned sulfur dioxide. Based on this, the inventors of the present application provide a sulfur dioxide storage device and a glass kiln for a glass kiln in one or more embodiments. The sulfur dioxide storage device is connected by two heating layers, and the gas storage tank is covered in the heating layer. The gas storage tank is heated by hot water in the coil so that the temperature of the sulfur dioxide gas discharged from the gas storage tank meets the requirements of the glass processing technology, thereby ensuring the glass processing quality. It is believed that it can solve one or more problems in the prior art.

[0029] In view of the above-mentioned technical problems, the utility model provides a sulfur dioxide storage device for a glass furnace, such as Figure 1 and Figure 2 As shown, it includes: a gas storage tank 1, which is used to store sulfur dioxide gas; a heating mechanism, which includes a heating layer 2, and the heating layer 2 includes two heating layers 2, and the two heating layers 2 are connected to cover the gas storage tank 1 in the heating layer 2; wherein the heating layer 2 includes a coil 3, and the coil 3 includes a water inlet 4, and the water inlet 4 is used to discharge hot water into the coil 3 to heat the sulfur dioxide gas in the gas storage tank 1.

[0030] Specifically, when glass production uses purchased sulfur dioxide, the sulfur dioxide gas is usually stored in a gas tank 1 and transported to a glass production plant. Before the sulfur dioxide gas is introduced into the bottom of the slag box of the glass kiln, the sulfur dioxide in the gas tank 1 needs to be heated. First, two heating layers 2 are coated on the gas tank 1, and hot water is discharged into the coil 3 through the water inlet 4. The hot water exchanges heat with the gas tank 1 during the flow in the coil 3, thereby heating the sulfur dioxide in the gas tank 1. Specifically, the coil 3 also includes a water outlet 8, so that circulating hot water is formed in the coil 3, thereby ensuring the heating effect on the sulfur dioxide. Furthermore, the circulating water can be heated by the heater and the waste heat of the glass kiln. After being heated in the heater, the circulating water is discharged into the coil 3 through the water inlet 4. After completing the heat exchange with the gas tank 1 in the coil 3, the circulating water returns to the heater through the water outlet 8 and is heated by the waste heat of the glass kiln before being recycled again. Energy conservation and emission reduction are achieved by using the waste heat of the circulating water and the glass kiln. Specifically, the shape of the heating layer 2 should fit the shape of the gas tank 1 to ensure that the heating layer 2 can tightly wrap the gas tank 1 therein, thereby ensuring the heating effect. The coil 3 can be made of a material with excellent thermal conductivity to ensure heat exchange efficiency.

[0031] Compared with the prior art, the sulfur dioxide storage device of a glass kiln in the present application connects two heating layers 2, covers a gas storage tank 1 in the heating layer 2, and heats the gas storage tank 1 with hot water in a coil 3, so that the temperature of the sulfur dioxide gas discharged from the gas storage tank 1 meets the requirements of the glass processing technology, thereby ensuring the quality of glass processing.

[0032] In some embodiments, Figure 1 As shown, it also includes an insulation layer 5, which is laid on the outer wall of the heating layer 2. The insulation layer 5 prevents the hot water in the coil 3 from exchanging heat with the environment, thereby avoiding the problem of energy waste. Specifically, the insulation layer 5 can be made of materials with low thermal conductivity such as rock wool or glass wool. Furthermore, a reinforcement layer can be provided outside the insulation layer 5 to ensure the structural strength and integrity of the insulation layer 5. Specifically, the reinforcement layer can be made of materials such as iron sheets.

[0033] In some embodiments, Figure 1 As shown, the heating layer 2 further includes a frame 6, and the coil 3 is arranged on the frame 6. The stability and integrity of the structure of the coil 3 are ensured by the frame 6. Specifically, the frame 6 can be a steel structure, and the shape of the frame 6 must fit the shape of the gas tank 1. Furthermore, a heat insulation pad can be provided at the connection between the coil 3 and the frame 6 to prevent the hot water in the coil 3 from exchanging heat with the frame 6.

[0034] In some embodiments, a connector is provided on the top of the frame 6 for connecting the two heating layers 2. The two heating layers 2 can be firmly connected together by the connector so that the gas storage tank 1 can be tightly wrapped in the heating layer 2. Specifically, the connector can be a buckle or a bolt.

[0035] In some embodiments, Figure 1 and Figure 2 As shown, a pulley 7 is provided on the bottom of the frame 6. The pulley 7 facilitates the movement of the gas storage tank 1 and also facilitates the docking of the two heating layers 2. Specifically, the pulley 7 can be a universal wheel.

[0036] In some embodiments, a brake pad is provided on the pulley 7. The brake pad avoids the safety problem caused by the pulley 7 sliding by itself.

[0037] In some embodiments, a flow meter is provided on the water inlet 4 to monitor the flow of hot water discharged into the coil 3. The flow meter can monitor the flow of hot water discharged into the coil 3 in real time, and the flow of hot water can be controlled by the control valve according to the monitored flow, thereby ensuring the heating temperature of the sulfur dioxide gas.

[0038] In some embodiments, a first thermometer is further provided on the water inlet 4 to monitor the temperature of the hot water discharged into the coil 3. The temperature of the hot water discharged into the coil 3 can be monitored in real time by the first thermometer to ensure the heating effect of the hot water in the coil 3 on the sulfur dioxide gas in the gas storage tank 1.

[0039] In some embodiments, a second thermometer is provided on the gas outlet of the gas storage tank 1 to monitor the temperature of the sulfur dioxide gas discharged from the gas storage tank 1. The temperature of the sulfur dioxide gas can be monitored in real time by the second thermometer to ensure that the temperature of the sulfur dioxide gas provided to the slag box of the glass kiln meets the process requirements.

[0040] The present application also provides a glass furnace, including a slag box and the above-mentioned sulfur dioxide storage device of the glass furnace connected to the slag box. The purchased sulfur dioxide gas can be heated by the heating layer 2 to ensure the processing quality of the glass.

[0041] In summary, compared with the prior art, the present invention provides a sulfur dioxide storage device and a glass kiln for a glass kiln, wherein the sulfur dioxide storage device is connected via two heating layers 2, a gas tank 1 is wrapped in the heating layer 2, and the gas tank 1 is heated by hot water in the coil 3, so that the temperature of the sulfur dioxide gas discharged from the gas tank 1 meets the requirements of the glass processing technology, thereby ensuring the glass processing quality; the thermal insulation layer 5 prevents the hot water in the coil 3 from heat exchange with the environment, thereby avoiding the problem of energy waste; the stability and integrity of the coil 3 structure are ensured by the skeleton 6; the movement of the gas tank 1 is facilitated by the pulley 7, and the connection of the two heating layers 2 is also facilitated; the heating effect of the sulfur dioxide gas in the gas tank 1 is ensured by the flow meter and the first thermometer.
