[0025] like Figure 1 and Figure 2As shown, the embodiment relates to a glass furnace oxygen supply device, which is connected to the glass furnace, and the glass furnace oxygen supply device includes: an air separation component 10 and an oxygen supply component 20. The air separation component 10 includes a fractionation tower 11, a first air duct 12 and a heat exchanger 13, and the first air duct 12 is first connected to the fractionation tower 11 through the heat exchanger 13. The oxygen supply assembly 20 includes a first oxygen supply structure 21, a second oxygen supply structure 22 and a third oxygen supply structure 23. The first oxygen supply structure 21 includes a first oxygen pipeline 211, the second oxygen supply structure 22 includes a second oxygen pipeline 221, and the third oxygen supply structure 23 includes a third oxygen pipeline 231. The air inlet end of the first oxygen pipeline 211 is connected to the distillation tower 11, and the air outlet end of the first oxygen pipeline 211 is connected to both the second oxygen pipeline 221 and the third oxygen pipeline 231. The first oxygen supply structure 21 also includes a first regulating valve 212 and a muffler 213, and the first regulating valve 212 and the muffler 213 are both arranged on the first oxygen pipeline 211. The second oxygen supply structure 22 also includes an electric regulating valve 222, and the electric regulating valve 222 is arranged on the second oxygen pipeline 221. The third oxygen supply structure 23 also includes a buffer tank 232 and an oxygen compressor 233, and the buffer tank 232 and the oxygen compressor 233 are both arranged on the third oxygen pipeline 231.

[0026] By applying the technical solution of this embodiment, air is heat exchanged from the first air pipe 12 through the heat exchanger 13, and enters the fractionation tower 11 after cooling. Oxygen is obtained by deep cold air separation in the fractionation tower 11. The first oxygen pipe 211 is connected with the heat exchanger 13. Oxygen is discharged from the fractionation tower 11 through the first oxygen pipe 211, and then reheated by the heat exchanger, and then transported to the second oxygen pipe 221 and the third oxygen pipe 231. The first regulating valve 212 can control the flow of oxygen in the first oxygen pipe 211, and the muffler 213 can eliminate the noise generated when the first regulating valve 212 is working. The oxygen entering the second oxygen pipe 221 is adjusted by the electric regulating valve 222, and the pressure and flow of oxygen can be accurately regulated by the electric regulating valve 222. The third oxygen pipeline 231 is provided with a buffer tank 232 and an oxygen compressor 233. The oxygen in the third oxygen pipeline 231 is used to supplement oxygen to the middle part of the kiln to maintain the high temperature effect. The buffer tank 232 can adjust the pressure fluctuation of the pipeline, and the oxygen compressor 233 can increase the oxygen concentration and improve the combustion efficiency. The technical solution of this embodiment effectively solves the problem that the noise is not eliminated and the input oxygen concentration is low in the prior art.

[0027] In some embodiments, the first oxygen pipeline has a connecting section and an exhaust section, the first end of the connecting section is connected to the fractionation tower, the second end is connected to the second oxygen pipeline 221, the third oxygen pipeline 231 and the exhaust section, the muffler and the first regulating valve 212 are arranged on the exhaust section, when the pipeline pressure is too large and needs to be discharged, the first regulating valve 212 is opened, and the oxygen is discharged through the exhaust section, and the oxygen is first silenced by the muffler when it is discharged, and the muffler is an oxygen dissipation muffler, and the oxygen dissipation muffler includes a muffler shell and a sound absorbing body, and the gas is discharged after passing through the sound absorbing body to resist sound and absorb sound, which effectively reduces noise pollution. The oxygen compressor 233 is a compressor specially used for compressing oxygen, which creates pressure in the cylinder through a rotating piston, so that the oxygen rises from low pressure to high pressure.

[0028] It should be noted that the glass kiln oxygen supply device also includes a pipeline control system, which can be a terminal DCS or PLC controller. The pipeline control system is electrically connected to the electric regulating valve 222 and the first regulating valve 212, and can control the opening size of the electric regulating valve 222 and the first regulating valve 212.

[0029] like Figure 1 and Figure 2 As shown, in some embodiments, the second oxygen delivery structure 22 further includes a first flow meter 223 and an emergency shut-off valve 224. The first flow meter 223 and the emergency shut-off valve 224 are both arranged on the second oxygen pipeline 221. The first flow meter 223 can detect the flow of oxygen in the second oxygen pipeline 221 to determine whether the oxygen flow is within a qualified range. The emergency shut-off valve 224 is close to the air inlet end of the second oxygen pipeline 221. The emergency shut-off valve 224 and the first flow meter 223 are both electrically connected to the pipeline control system. Once the first flow meter 223 detects that the fluctuation of oxygen is abnormal, it transmits a signal to the pipeline control system, and the pipeline control system controls the emergency shut-off valve 224 to cut off to prevent adverse consequences. When the pressure and / or flow of oxygen in the second oxygen pipeline 221 exceeds the set value, it may be caused by insufficient heat exchange of oxygen. At this time, the emergency shut-off valve 224 cuts off the second oxygen pipeline 221 in time to prevent low-temperature oxygen from causing pipeline brittleness and causing production accidents.

[0030] like Figure 1 and Figure 2As shown, in some embodiments, the first oxygen delivery structure 21 further includes a second flow meter 214, a pressure detector 215, and a temperature detector 216. The second flow meter 214, the pressure detector 215, and the temperature detector 216 are all arranged on the first oxygen pipeline 211 and are located in front of the first regulating valve 212. The positional relationship between the three can be adjusted without affecting the detection result. The second flow meter 214, the pressure detector 215, and the temperature detector 216 are all electrically connected to the pipeline control system, and can transmit the detected signal to the pipeline control system, so that the pipeline control system can control the first regulating valve 212.

The first valve 226 and the second valve 227 can be stop valves. When the first flow meter 223 is inspected and repaired, the first valve 226 and the second valve 227 are closed, and the first bypass valve 228 is opened. At this time, the first branch pipeline 225 and the second oxygen pipeline 221 are connected to transport oxygen. It should be noted that the first valve 226, the second valve 227 and the first bypass valve 228 can all be electrically connected to the pipeline control system, and the pipeline control system performs intelligent control, or they can be manually adjusted.

[0032] like Figure 1 and Figure 2As shown, in some embodiments, the oxygen supply assembly 20 also includes a combustion-supporting wind box 24, which is connected to the air outlet end of the second oxygen pipeline 221. The second oxygen supply structure 22 also includes a first pressure gauge 229 and a second pressure gauge. The first pressure gauge 229 is arranged close to the electric regulating valve 222. The first pressure gauge 229 can detect the oxygen pressure before the electric regulating valve 222 and transmit the detection result to the pipeline control system. The second pressure gauge is arranged close to the combustion-supporting wind box 24 and can further detect the oxygen pressure entering the combustion-supporting wind box 24. The second oxygen supply structure 22 also includes a first manual valve and a second manual valve, both of which are arranged on the second oxygen pipeline 221, the first manual valve is close to the air inlet end of the second oxygen pipeline 221, and the second manual valve is close to the air outlet end of the second oxygen pipeline 221. The first manual valve and the second manual valve are usually in a fully open state, and the flow and pressure are controlled by the electric regulating valve 222. When a special situation occurs, for example, the electric regulating valve 222 fails to receive the signal of the pipeline control system in time and make adjustments, the first manual valve and the second manual valve can be manually operated to make adjustments. It should be noted that the oxygen is sent to the combustion-supporting wind box 24 by forced extraction through the fan set at the combustion-supporting wind box 24, and the combustion-supporting wind box 24 is connected to the front end of the glass kiln to send oxygen to the kiln. It should also be noted that the first pressure gauge 229 and the second pressure gauge are both electrically connected to the pipeline control system, and can transmit the detected signal to the pipeline control system, and the pipeline control system controls the opening of the electric regulating valve 222 according to the detection signal.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, the third oxygen delivery structure 23 further includes a second regulating valve 234 and a third regulating valve 235, both of which are arranged on the third oxygen pipeline 231, the second regulating valve 234 is close to the air inlet end of the buffer tank 232, the second regulating valve 234 can control the oxygen flow entering the buffer tank 232, the buffer tank 232 reduces the change of air pressure by increasing the container volume, and the buffer tank 232 can reduce the noise generated by the third oxygen pipeline 231 when transporting oxygen, the third regulating valve 235 is close to the air outlet end of the buffer tank 232, and can regulate the oxygen flow out of the buffer tank 232, the second regulating valve 234 and the third regulating valve 235 cooperate with each other to control the oxygen flow flowing into or out of the buffer tank 232. It should be noted that all types of regulating valves in this application are not specifically limited, and can achieve the regulation of flow and pressure.

[0034] like Figure 1 and Figure 2As shown, in some embodiments, the third oxygen supply structure 23 also includes a check valve 236 and an outlet valve 237, both of which are arranged on the third oxygen pipeline 231, and the check valve 236 is arranged near the oxygen compressor 233. The check valve 236 is arranged downstream of the oxygen compressor 233, and the check valve 236 can prevent the oxygen after the oxygen compressor 233 is pressurized from flowing back. The backflow will not only cause the oxygen compressor 233 to work repeatedly, but also affect the oxygen output effect of the third oxygen pipeline 231. The outlet valve 237 can control the oxygen flow and pressure in the third oxygen pipeline 231, and deliver stable oxygen to the middle of the glass furnace. A third flow meter is arranged downstream of the third oxygen pipeline 231, and the third flow meter is electrically connected to the pipeline control system, and can transmit the detected signal to the pipeline control system, and the pipeline control system controls the outlet valve 237 according to the detection result.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the third oxygen delivery structure 23 also includes a second pipeline, a third valve, a fourth valve, a second bypass valve and a pneumatic regulating valve. The third valve, the fourth valve and the pneumatic regulating valve are all arranged on the third oxygen pipeline 231, the second bypass valve is arranged on the second pipeline, and the pneumatic regulating valve is located between the third valve and the fourth valve.

The opening of the valve is controlled by a pneumatic actuator to adjust the oxygen flow rate. The specific structure is not described in detail here. The third valve and the fourth valve can be stop valves. When the pneumatic regulating valve is inspected and repaired, the third valve and the fourth valve are closed, and the second bypass valve is opened. At this time, the second pipeline and the third oxygen pipeline 231 are connected to transport oxygen. It should be noted that the third valve, the fourth valve and the second bypass valve can all be electrically connected to the pipeline control system, and the pipeline control system can be intelligently controlled, or they can be manually adjusted.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the oxygen supply assembly 20 further includes a furnace burner 25, and the furnace burner 25 is connected to the third oxygen pipeline 231. The other end of the furnace burner 25 is connected to the middle of the glass furnace. Since the glass furnace is large in size, the middle of the glass furnace will have insufficient combustion-supporting gas to affect the calorific value during combustion, so the third oxygen supply structure and the furnace burner 25 are provided to supplement oxygen.
