[0063] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0064] like Figure 1 As shown, according to an embodiment of the present disclosure, a combustion heating system is proposed, including: a combustion heating device 100, used for combustion heating; a gas supply pipeline 200, used for conveying gas, and the air inlet end of the gas supply pipeline 200 is used to be connected to the gas supply device 800; an oxygen supply pipeline 300, used for conveying oxygen, and the air inlet end of the oxygen supply pipeline 300 is used to be connected to the oxygen supply device 900; a distributor 400, the air outlet end of the gas supply pipeline 200 and the air outlet end of the oxygen supply pipeline 300 are both connected to the distributor 400, the distributor 400 is used to mix gas and oxygen in proportion, and the air outlet end of the distributor 400 is connected to the air inlet of the combustion heating device 100.

[0065] The combustion and heating system proposed according to the embodiment of the present disclosure includes a combustion and heating device 100, a gas supply device 800, an oxygen supply device 900 and a distributor 400, wherein the gas supply pipeline 200 is connected with the gas supply device 800, the gas supply device 800 provides gas and transports it to the distributor 400 through the gas supply pipeline 200, the oxygen supply pipeline 300 is connected with the oxygen supply device 900, the oxygen supply device 900 provides oxygen and transports it to the distributor 400 through the oxygen supply pipeline 300, and the distributor 400 is used to mix the gas transported by the gas supply pipeline 200 and the oxygen transported by the oxygen supply pipeline 300 in proportion, and then transport the mixed gas from the distributor 400 to the combustion and heating device 100 for combustion, so that the gas can be fully burned, thereby reducing the emission of pollutants.

[0066] It can be understood that the gas mixed by the distributor 400 has a higher combustion efficiency and is more conducive to more complete combustion of the gas.

[0067] It is understandable that the fuel gas may be coal gas, natural gas, hydrogen, liquefied petroleum gas and other fuels. Different types of fuel gas have different mixing ratios with oxygen. The mixing ratio of the fuel gas and oxygen in the distributor 400 may be set according to the type of fuel gas.

[0068] It should be noted that the combustion and heating system of the traditional asphalt mixing plant uses diesel or heavy oil as fuel and air as a combustion aid. In this way, liquid fuels such as diesel or heavy oil are difficult to burn completely, resulting in a large amount of harmful gases and pollutants such as volatile organic compounds, which seriously pollute the surrounding environment. Compared with the prior art, the gas heating system proposed in the embodiment of the present disclosure uses gas as fuel. Compared with traditional liquid fuels such as diesel or heavy oil, on the one hand, it is easier to mix with the combustion aid, which is conducive to full combustion, thereby reducing the emission of pollutants. On the other hand, the cost of gas is relatively low, which can reduce the combustion cost; at the same time, the embodiment of the present disclosure uses oxygen as a combustion aid, which has a stronger combustion effect, and compared with air as a combustion aid, it can greatly reduce the generation of nitrogen oxides and avoid nitrogen oxides from polluting the environment.

[0069] Exemplarily, the gas supply method may be large gas storage tanks, 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.

[0070] Exemplarily, the distributor 400 has a first air inlet end and a second air inlet end, the first input end is used to input oxygen, and the second input end is used to input fuel gas. The distributor 400 also includes a first distribution valve and a second distribution valve. The first distribution valve is arranged at the first air inlet end, and the first distribution valve is used to control the gas input amount of the first air inlet end. The second distribution valve is arranged at the second air inlet end, and the second distribution valve is used to control the gas input amount of the second air inlet end. The oxygen input amount can be controlled by the first distribution valve and the fuel gas input amount can be controlled by the second distribution valve, so that the proportional mixing of fuel gas and oxygen is achieved by controlling the input amount ratio of oxygen and fuel gas in the distributor 400.

[0071] In some examples, such as Figure 1 As shown, the oxygen supply pipeline 300 includes: a first oxygen cut-off valve 301, which is used to be arranged between the oxygen supply device 900 and the distributor 400; an oxygen buffer tank 302, which is arranged between the first oxygen cut-off valve 301 and the distributor 400; and a second oxygen cut-off valve 303, which is arranged between the oxygen buffer tank 302 and the distributor 400.

[0072] In the above technical solution, the oxygen supply pipeline 300 includes a first oxygen cut-off valve 301, an oxygen buffer tank 302 and a second oxygen cut-off valve 303. Along the supply direction of oxygen, the first oxygen cut-off valve 301, the oxygen buffer tank 302 and the second oxygen cut-off valve 303 are arranged in sequence. The first oxygen cut-off valve 301 is used to control whether oxygen can flow from the oxygen supply device 900 into the oxygen buffer tank 302, and the second oxygen cut-off valve 303 is used to control the flow of oxygen from the oxygen buffer tank 302 into the distributor 400. In actual application, oxygen first passes through the first oxygen cut-off valve 301 from the oxygen supply device 900 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 distributor 400 and affecting the function of the distributor 400.

[0073] 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 cut-off valve 301 and the second oxygen cut-off valve 303 are both used to control the conduction or cut-off of the oxygen supply channel. When the oxygen supply channel is conducted, oxygen can flow in the oxygen supply channel. When the oxygen supply channel is cut off, oxygen cannot flow in the oxygen supply channel.

[0074] In some examples, such as Figure 1As shown, the oxygen supply pipeline 300 also includes: a first oxygen pressure gauge 304, which is arranged between the second oxygen shut-off valve 303 and the distributor 400; an oxygen pressure regulating valve 305, which is arranged between the first oxygen pressure gauge 304 and the distributor 400; a second oxygen pressure gauge 306, which is arranged between the oxygen pressure regulating valve 305 and the distributor 400; an oxygen flow regulating valve 307, which is arranged between the first oxygen pressure gauge 304 and the distributor 400; and an oxygen flow meter 308, which is arranged between the oxygen flow regulating valve 307 and the distributor 400.

[0075] In the above technical solution, the oxygen supply pipeline 300 includes a first oxygen pressure gauge 304, an oxygen pressure regulating valve 305, a second oxygen pressure gauge 306, an oxygen flow regulating valve 307 and an oxygen flow meter 308, wherein the first oxygen pressure gauge 304 is arranged between the second oxygen shut-off valve 303 and the distributor 400, the first oxygen pressure gauge 304 is used to detect the oxygen pressure output by the oxygen buffer tank 302, the oxygen pressure regulating valve 305 is arranged between the first oxygen pressure gauge 304 and the distributor 400, the oxygen pressure regulating valve 305 is used to adjust the oxygen pressure, and the oxygen pressure can be adjusted by the oxygen pressure regulating valve 305 according to the oxygen pressure detected by the first oxygen pressure gauge 304; an oxygen second pressure gauge 306 is also arranged between the oxygen pressure regulating valve 305 and the distributor 400. The gauge 306 is used to detect the oxygen pressure after being adjusted by the oxygen pressure regulating valve 305 to ensure that the air pressure delivered to the distributor 400 meets the requirements and avoids the excessive oxygen pressure affecting the function of the distributor 400. At the same time, the second oxygen pressure gauge 306 can also be observed to adjust the oxygen pressure in the pipeline by adjusting the oxygen pressure regulating valve 305. The oxygen flow regulating valve 307 is arranged between the first oxygen pressure gauge 304 and the distributor 400 and is used to adjust the oxygen flow in the pipeline. An oxygen flow meter 308 is also arranged between the oxygen flow regulating valve 307 and the distributor 400. The oxygen flow meter 308 is used to detect the oxygen flow information in the pipeline. The oxygen flow regulating valve 307 can be adjusted according to the oxygen flow information detected by the oxygen flow meter 308 to avoid excessive oxygen flow delivered to the distributor 400.

[0076] It is understandable that the oxygen pressure regulating valve 305 and the oxygen flow regulating valve 307 can adjust the amount of oxygen delivered to the distributor 400 according to usage requirements and the combustion conditions of the combustion and heating device 100 .

[0077] It is understandable that an oxygen filter 321 may be provided between the first oxygen pressure gauge 304 and the second oxygen shut-off valve 303. The oxygen filter 321 may remove rust or other mechanical impurities to avoid sparks caused by friction and thus cause explosion accidents.

[0078] In some examples, such as Figure 1As shown, the oxygen supply pipeline 300 also includes: an oxygen dispersing device 309, which is arranged between the oxygen pressure regulating valve 305 and the distributor 400, wherein the oxygen dispersing device 309 has an oxygen dispersing port and an oxygen shut-off valve, and the oxygen shut-off valve has an on state and a shut-off state. When the oxygen shut-off valve is in the on state, oxygen can be discharged from the oxygen dispersing port. When the oxygen shut-off valve is in the shut-off state, the oxygen shut-off valve restricts the discharge of oxygen from the oxygen dispersing port.

[0079] In the above technical solution, the oxygen supply pipeline 300 also includes an oxygen dispersing device 309, which is arranged between the oxygen pressure regulating valve 305 and the distributor 400. The oxygen dispersing device 309 has an oxygen dispersing port and an oxygen shut-off valve. The oxygen dispersing port is used to discharge oxygen, and the oxygen shut-off valve is used to control the conduction or cut-off of the oxygen dispersing port. By conducting the oxygen shut-off valve, the oxygen dispersing port can discharge oxygen, and the oxygen in the pipeline can be sampled or detected.

[0080] It is understandable that the oxygen pressure discharged from the oxygen discharging port of the oxygen discharging device 309 can be adjusted by the oxygen pressure regulating valve 305 .

[0081] It is understandable that the oxygen dispersing port of the oxygen dispersing device 309 can also be used to connect to the oxygen supply pipeline 300 of other devices to provide oxygen for other devices.

[0082] In some examples, such as Figure 1 As shown, the oxygen supply pipeline 300 also includes: an oxygen safety valve 310, which is arranged between the oxygen pressure regulating valve 305 and the second oxygen pressure gauge 306; the oxygen safety valve 310 has an oxygen pressure relief port; an oxygen check valve 311, which is arranged between the oxygen safety valve 310 and the distributor 400; wherein, the oxygen safety valve 310 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 when the oxygen pressure value is greater than the oxygen safety pressure threshold, the oxygen pressure relief port is opened.

[0083] In the above technical solution, the oxygen supply pipeline 300 also includes an oxygen safety valve 310, which is arranged between the oxygen pressure regulating valve 305 and the second oxygen pressure gauge 306. The oxygen safety valve 310 can protect the second oxygen pressure gauge 306 and the distributor 400, and prevent the second oxygen pressure gauge 306 and the distributor 400 from being impacted by high-pressure oxygen; the oxygen safety valve 310 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 oxygen pressure 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 gauge 306 and the distributor 400 from being impacted by high-pressure oxygen; the oxygen supply pipeline 300 also includes an oxygen check valve 311 arranged between the oxygen safety valve 310 and the distributor 400, so that oxygen can only flow from the oxygen safety valve 310 to the distributor 400, and oxygen can be prevented from flowing back from the distributor 400.

[0084] In some examples, such as Figure 1 As shown, the gas supply pipeline 200 includes: a first gas cut-off valve 201, which is used to be set between the gas supply device 800 and the distributor 400; a gas buffer tank 202, which is set between the first gas cut-off valve 201 and the distributor 400; and a second gas cut-off valve 203, which is set between the gas buffer tank 202 and the distributor 400.

[0085] In the above technical solution, the gas supply pipeline 200 includes a first gas shut-off valve 201, a gas buffer tank 202 and a second gas shut-off valve 203. Along the supply direction of the gas, the first gas shut-off valve 201, the gas buffer tank 202 and the second gas shut-off valve 203 are arranged in sequence. The first gas shut-off valve 201 is used to control whether the gas can flow from the gas supply device 800 into the gas buffer tank 202. The second gas shut-off valve 203 is used to control the gas from the gas buffer tank 202 into the distributor 400. In actual applications, the gas first passes through the first gas shut-off valve 201 from the gas supply device 800 and enters the gas buffer tank 202. The gas buffer tank 202 has a buffering effect, which can slow down the flow rate of the gas and prevent the high-pressure gas from directly impacting the distributor 400 and affecting the function of the distributor 400.

[0086] It can be understood that a gas supply channel is formed inside the gas supply pipeline 200, and the gas supply channel is used to transport gas. The first gas cut-off valve 201 and the second gas cut-off valve 203 are both used to control the conduction or cut-off of the gas supply channel. When the gas supply channel is conducted, the gas can flow in the gas supply channel. When the gas supply channel is cut off, the gas cannot flow in the gas supply channel.

At the same time, the second gas pressure gauge 206 can also be observed to adjust the gas pressure in the pipeline by adjusting the gas pressure regulating valve 205. The gas flow regulating valve 207 is arranged between the first gas pressure gauge 204 and the distributor 400 and is used to adjust the gas flow in the pipeline. A gas flow meter 208 is also arranged between the gas flow regulating valve 207 and the distributor 400. The gas flow meter 208 is used to detect the gas flow information in the pipeline. The gas flow regulating valve 207 can be adjusted according to the gas flow information detected by the gas flow meter 208 to avoid excessive gas flow delivered to the distributor 400.

[0089] It is understandable that the gas pressure regulating valve 205 and the gas flow regulating valve 207 can adjust the amount of gas delivered to the distributor 400 according to usage requirements and the combustion conditions of the combustion and heating device 100.

[0090] It is understandable that a gas filter 221 may be provided between the first gas pressure gauge 204 and the second gas shut-off valve 203. The gas filter 221 may remove rust or other mechanical impurities to avoid sparks caused by friction and thus cause explosion accidents.

[0091] In some examples, such as Figure 1As shown, the gas supply pipeline 200 also includes: a gas dispersing device 209, which is arranged between the gas pressure regulating valve 205 and the distributor 400, wherein the gas dispersing device 209 has a gas dispersing port and a gas shut-off valve, and the gas shut-off valve has an on state and a shut-off state.

By conducting the gas shut-off valve, the gas dispersing port can discharge gas, and the gas in the pipeline can be sampled or tested.

[0093] It is understandable that the gas pressure discharged from the gas discharging port of the gas discharging device 209 can be adjusted by the gas pressure regulating valve 205 .

[0094] It is understandable that the gas discharging port of the gas discharging device 209 can also be used to connect to the gas supply pipeline 200 of other devices to provide gas for other devices.

[0095] In some examples, such as Figure 1 As shown, the gas supply pipeline 200 also includes: a gas safety valve 210, which is arranged between the gas pressure regulating valve 205 and the second gas pressure gauge 206, and the gas safety valve 210 has a gas pressure relief port; a gas check valve 211, which is arranged between the gas safety valve 210 and the distributor 400; wherein, the gas safety valve 210 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 when the gas pressure value is greater than the gas safety pressure threshold, the gas pressure relief port is opened.
