[0079] It is understandable that the fuel gas can be coal gas, natural gas, hydrogen, liquefied petroleum gas, etc. Compared with traditional liquid fuels such as diesel or heavy oil, using fuel gas as fuel is more conducive to full combustion and can also save combustion costs.

[0080] It can be understood that after the oxygen-enriching device 500 mixes oxygen with air, an oxygen-enriched gas with an oxygen volume content higher than 21% can be obtained. The oxygen-enriched gas replaces air as a combustion aid, which is beneficial to increase the flame temperature during combustion, increase the combustion speed and efficiency, and thus improve production efficiency.

[0081] It is understandable that the oxygen pressure input from the oxygen supply pipeline 300 to the oxygen enrichment device 500 should be greater than the air pressure input from the air supply pipeline 400 to the oxygen enrichment device 500 by more than 0.1 MPa, so as to prevent air from entering the oxygen supply pipeline 300 from the oxygen enrichment device 500.

[0082] Exemplarily, the gas supply method may be a large gas storage tank, liquid fuel vaporization, long-distance pipeline transportation, etc.; the oxygen supply method may be air separation oxygen production, liquid oxygen vaporization, long-distance pipeline transportation, etc.

[0084] In a feasible embodiment, using oxygen-enriched gas with an oxygen volume content higher than 21% as a combustion aid can increase the combustion flame temperature by 100-350°C.

[0085] In some examples, such as Figure 1 As shown, the oxygen supply pipeline 300 includes: a first oxygen stop valve 301, which is used to be arranged between the oxygen supply device 800 and the oxygen enrichment device 500; an oxygen buffer tank 302, which is arranged between the first oxygen stop valve 301 and the oxygen enrichment device 500; a second oxygen stop valve 303, which is arranged between the oxygen buffer tank 302 and the oxygen enrichment device 500; a first oxygen pressure detection member 304, which is arranged between the second oxygen stop valve 303 and the oxygen enrichment device 500; and a third oxygen stop valve 305, which is arranged between the oxygen between the first pressure detecting component 304 and the oxygen enriching device 500; the oxygen pressure regulating valve 306 is arranged between the first oxygen pressure detecting component 304 and the third oxygen stop valve 305; the second oxygen pressure detecting component 307 is arranged between the oxygen pressure regulating valve 306 and the third oxygen stop valve 305; the oxygen flow regulating valve 308 is arranged between the first oxygen pressure detecting component 304 and the third oxygen stop valve 305; the oxygen flow detecting component 309 is arranged between the oxygen flow regulating valve 308 and the third oxygen stop valve 305.

Along the supply direction of oxygen, the first oxygen stop valve 301, the oxygen buffer tank 302 and the second oxygen stop valve 303 are arranged in sequence. The first oxygen stop valve 301 is used to control whether oxygen can flow from the oxygen supply device 800 into the oxygen buffer tank 302, and the second oxygen stop valve 303 is used to control the flow of oxygen from the oxygen buffer tank 302 into the oxygen enrichment device 500. In actual application, oxygen first passes through the first oxygen stop valve 301 from the oxygen supply device 800 and enters the oxygen buffer tank 302. The oxygen buffer tank 302 has a buffering effect, which can slow down the flow rate of oxygen and prevent high-pressure oxygen from directly impacting the oxygen enrichment device 500 and affecting the function of the oxygen enrichment device 500.

[0087] It can be understood that an oxygen supply channel is formed inside the oxygen supply pipeline 300, and the oxygen supply channel is used to transport oxygen. The first oxygen stop valve 301 and the second oxygen stop valve 303 are both used to control the conduction or cutoff of the oxygen supply channel. When the oxygen supply channel is connected, oxygen can flow in the oxygen supply channel. When the oxygen supply channel is cutoff, oxygen cannot flow in the oxygen supply channel.

An oxygen second pressure detection component 307 is also provided between the stop valves 305, which is used to detect the oxygen pressure adjusted by the oxygen pressure regulating valve 306 to ensure that the air pressure delivered to the oxygen enrichment device 500 meets the requirements and avoids excessive oxygen pressure affecting the function of the oxygen enrichment device 500. At the same time, it can also be observed that the oxygen second pressure detection component 307 adjusts the oxygen pressure in the pipeline by adjusting the oxygen pressure regulating valve 306.

The oxygen flow regulating valve 308 can be adjusted according to the oxygen flow information detected by the oxygen flow detection component 309 to avoid excessive oxygen flow delivered to the oxygen enrichment device 500.

[0089] It is understandable that the oxygen pressure regulating valve 306 and the oxygen flow regulating valve 308 can adjust the amount of oxygen delivered to the oxygen enrichment device 500 according to usage requirements and the combustion conditions of the combustion heating device 100 .

[0090] It is understandable that an oxygen filter 314 may be provided between the first oxygen pressure detection member 304 and the second oxygen stop valve 303.

[0093] In the above technical solution, the oxygen supply pipeline 300 also includes an oxygen dispersing device 310, which is arranged between the oxygen pressure regulating valve 306 and the third oxygen shut-off valve 305. The oxygen dispersing device 310 has a dispersing port and a first valve body. The dispersing port is used to discharge oxygen, and the first valve body is used to control the conduction or cutoff of the dispersing port. By conducting the first valve body, the dispersing port can discharge oxygen, and the oxygen in the pipeline can be sampled or detected.

[0094] It is understandable that the pressure of oxygen discharged from the discharge port of the oxygen dispersing device 310 can be adjusted by the oxygen pressure regulating valve 306 .

[0095] It is understandable that the release port of the oxygen release device 310 can also be used to connect to the oxygen supply pipeline 300 of other devices to provide oxygen for other devices.

The oxygen safety valve 311 is arranged between the oxygen pressure regulating valve 306 and the oxygen second pressure detecting component 307. The oxygen safety valve 311 can protect the oxygen second pressure detecting component 307 and the oxygen enriching device 500, and prevent the oxygen second pressure detecting component 307 and the oxygen enriching device 500 from being impacted by high-pressure oxygen; the oxygen safety valve 311 is preset with an oxygen safety pressure threshold. When the oxygen pressure value is less than or equal to the oxygen safety pressure threshold, the oxygen pressure relief port is closed, and oxygen cannot be discharged from the pressure relief port. When the value is greater than the oxygen safety pressure threshold, the oxygen pressure relief port is opened, and oxygen can be discharged from the oxygen pressure relief port, thereby reducing the pressure of oxygen in the pipeline and preventing the second oxygen pressure detection component 307 and the oxygen enrichment device 500 from being impacted by high-pressure oxygen; the oxygen supply pipeline 300 also includes an oxygen one-way valve 312 arranged between the third oxygen stop valve 305 and the oxygen enrichment device 500, which can make oxygen flow to the oxygen enrichment device 500 in one direction only, and can prevent oxygen from flowing back from the oxygen enrichment device 500; the oxygen flame arrester 313 is arranged between the third oxygen stop valve 305 and the oxygen enrichment device 500, and is used to prevent flames from entering the oxygen supply pipeline 300 and causing safety accidents.

[0102] It is understandable that the gas pressure regulating valve 206 and the gas flow regulating valve 208 can adjust the amount of gas delivered to the combustion and heating device 100 according to usage requirements and the combustion conditions of the combustion and heating device 100.

[0103] It is understandable that a gas filter 214 may be provided between the first gas pressure detection element 204 and the second gas shut-off valve 203. The gas filter 214 may remove rust or other mechanical impurities to avoid sparks caused by friction and thus cause explosion accidents.

[0104] In some examples, such as Figure 1As shown, the gas supply pipeline 200 also includes: a gas dispersing device 210, which is arranged between the gas pressure regulating valve 206 and the third gas shut-off valve 205; wherein the gas dispersing device 210 has a gas dispersing port and a second valve body, and the second valve body has a conducting state and a shut-off state. When the second valve body is in the conducting state, the gas can be discharged from the gas dispersing port, and when the second valve body is in the shut-off state, the second valve body restricts the gas from being discharged from the gas dispersing port.

[0105] In the above technical solution, the gas supply pipeline 200 also includes a gas dispersing device 210, which is arranged between the gas pressure regulating valve 206 and the third gas shut-off valve 205. The gas dispersing device 210 has a dispersing port and a second valve body. The dispersing port is used for discharging gas, and the second valve body is used to control the conduction or cutoff of the dispersing port. By conducting the second valve body, the dispersing port can discharge gas, and the gas in the pipeline can be sampled or detected.

[0106] It is understandable that the gas pressure discharged from the discharge port of the gas discharge device 210 can be adjusted by the gas pressure regulating valve 206 .

[0107] It is understandable that the discharge port of the gas dispersing device 210 can also be used to connect to the gas supply pipeline 200 of other devices to provide gas for other devices.

[0108] In some examples, such as Figure 1 As shown, the gas supply pipeline 200 further includes: a gas safety valve 211, which is arranged between the gas pressure regulating valve 206 and the second gas pressure detecting member 207, and the gas safety valve 211 has a gas pressure relief port; a gas check valve 212, which is arranged between the third gas stop valve 205 and the combustion and heating device 100; and a gas flame arrester 213, which is arranged between the third gas stop valve 205 and the combustion and heating device 100. The gas safety valve 211 is preset with a gas safety pressure threshold, and when the gas pressure value is less than or equal to the gas safety pressure threshold, the gas pressure relief port is closed, and when the gas pressure value is greater than the gas safety pressure threshold, the gas pressure relief port is opened.

[0109] In the above technical solution, the gas supply pipeline 200 also includes a gas safety valve 211, a gas one-way valve 212 and a gas flame arrester 213. The gas safety valve 211 is arranged between the gas pressure regulating valve 206 and the second gas pressure detecting component 207. The gas safety valve 211 can protect the second gas pressure detecting component 207 and the combustion and heating device 100, and prevent the second gas pressure detecting component 207 and the combustion and heating device 100 from being impacted by high-pressure gas; the gas safety valve 211 is preset with a gas safety pressure threshold. When the gas pressure value is less than or equal to the gas safety pressure threshold, the gas pressure relief port is closed and the gas cannot be discharged from the pressure relief port. When the gas pressure value is greater than the gas pressure threshold, the gas pressure relief port is closed and the gas cannot be discharged from the pressure relief port. When the safety pressure threshold is reached, the gas pressure relief port opens and the gas can be discharged from the gas pressure relief port, thereby reducing the pressure of the gas in the pipeline and preventing the second gas pressure detection component 207 and the combustion and heating device 100 from being impacted by the high-pressure gas; the gas supply pipeline 200 also includes a gas one-way valve 212 arranged between the gas safety valve 211 and the combustion and heating device 100, which can make the gas only flow from the gas safety valve 211 to the combustion and heating device 100, and can prevent the gas from flowing back from the combustion and heating device 100; the gas flame arrester 213 is arranged between the third gas stop valve 205 and the combustion and heating device 100, and is used to prevent the flame from entering the gas supply pipeline 200 and causing a safety accident.

Along the air supply direction, the first air stop valve 401, the air buffer tank 402 and the second air stop valve 403 are arranged in sequence. The first air stop valve 401 is used to control whether the air can flow from the air supply device 900 into the air buffer tank 402, and the second air stop valve 403 is used to control the air to flow from the air buffer tank 402 into the oxygen enrichment device 500. In actual application, the air from the air supply device 900 first passes through the first air stop valve 401 and enters the air buffer tank 402. The air buffer tank 402 has a buffering effect, which can slow down the flow rate of the air and prevent the high-pressure air from directly impacting the oxygen enrichment device 500 and affecting the function of the oxygen enrichment device 500.

[0112] It can be understood that an air supply channel is formed inside the air supply pipeline 400, and the air supply channel is used to transport air. The first air stop valve 401 and the second air stop valve 403 are both used to control the conduction or cutoff of the air supply channel. When the air supply channel is conducted, air can flow in the air supply channel. When the air supply channel is cutoff, air cannot flow in the air supply channel.

[0113] In the above technical solution, the air supply pipeline 400 also includes a third air stop valve 405, an air pressure detection component 404, an air flow regulating valve 406 and an air flow detection component 407, wherein the third air stop valve 405 is used to control whether the air can enter the oxygen enrichment device 500, the air pressure detection component 404 is arranged between the second air stop valve 403 and the oxygen enrichment device 500, the air pressure detection component 404 is used to detect the air pressure output by the air buffer tank 402, the air flow regulating valve 406 is arranged between the air pressure detection component 404 and the third air stop valve 405, and is used to adjust the air flow in the pipeline, and an air flow detection component 407 is also arranged between the air flow regulating valve 406 and the third air stop valve 405, and the air flow detection component 407 is used to detect the air flow information in the pipeline, and the air flow regulating valve 406 can be adjusted according to the air flow information detected by the air flow detection component 407 to avoid excessive air flow delivered to the oxygen enrichment device 500.

[0114] In some examples, such as Figure 1 As shown, the air supply pipeline 400 further includes: an air one-way valve 408, which is arranged between the third air stop valve 405 and the oxygen enrichment device 500;

[0115] In the above technical solution, the air supply pipeline 400 also includes an air one-way valve 408 disposed between the third air stop valve 405 and the oxygen enrichment device 500, so that the air can only flow in one direction to the oxygen enrichment device 500, thereby preventing the air from flowing back from the oxygen enrichment device 500.

[0116] In some examples, such as Figure 1 As shown, it also includes: a quick-cut valve 601, and the gas supply pipeline 200, the oxygen supply pipeline 300 and the air supply pipeline 400 are all provided with a quick-cut valve 601.
