However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a low-nitrogen burner head for an industrial furnace, comprising a main body mechanism 1, and a combustion-supporting mechanism 2 is fixedly connected to the inner surface wall of the main body mechanism 1;

[0025] The combustion-supporting mechanism 2 includes an oxygen ring 201, the inner wall of the oxygen ring 201 is fixedly connected to a group of jet outlets 202, the outer wall of the oxygen ring 201 is fixedly connected to a pipeline 1 203, the input end of the pipeline 1 203 is fixedly connected to a circulation pump 204, the input end of the circulation pump 204 is fixedly connected to a gas treatment pipe 205, the inner wall of the gas treatment pipe 205 is fixedly connected to a group of heating plates 206, the inner wall of a group of heating plates 206 is fixedly connected to an inner ring 207, the inner wall of the inner ring 207 is provided with a group of sliding grooves 208, the inner walls of a group of sliding grooves 208 are all slidably embedded with sliding blocks 209, the outer walls of a group of sliding blocks 209 are all fixedly connected to adsorbent plates 210, the input end of the gas treatment pipe 205 is fixedly connected to a pipeline 211, and the input end of the pipeline 211 is fixedly connected to a compressor 212.

[0026] The effect achieved by the entire embodiment 1 is that, first, the compressor 212 can draw external gas into the interior, compress the gas inside the compressor 212, and the compressed gas is transported to the inside of the gas treatment tube 205. Then, when a group of heating plates 206 are energized, the current can be subjected to resistance inside the group of heating plates 206 to generate heat, which can keep the temperature inside the gas treatment tube 205 rising. A group of sliding blocks 209 are slidably embedded in the sliding groove 208, which can keep the adsorbent plate 210 installed inside the gas treatment tube 205. Under a certain temperature and pressure, nitrogen in the air will be preferentially adsorbed by the adsorbent plate 210, while oxygen can flow out smoothly through the output end of the gas treatment tube 205, thereby achieving the preliminary separation of oxygen.

[0027] Embodiment 2, as Figure 2-Figure 4 As shown, the main structure 1 includes an industrial furnace body 101, a gas outlet 102 is opened at the center of the bottom of the inner wall of the industrial furnace body 101, a hole 103 is opened on the outer wall of the industrial furnace body 101, a gas interface 104 is opened on the outer wall of the industrial furnace body 101, and the outer wall of the gas interface 104 is threadedly connected to a gas pipe 105, the outer wall of the oxygen ring 201 is fixedly installed with the inner wall of the industrial furnace body 101, and the outer wall of the pipeline 203 is fixedly inserted into the inside of the hole 103.

[0028] The effect achieved by the entire embodiment 2 is that, first, when the gas pipe 105 is threadedly connected to the inside of the gas interface 104, it can effectively keep the external combustion-supporting gas connected to the bottom of the industrial furnace body 101. Although when the combustion-supporting gas is continuously discharged through the gas outlet 102, it can effectively provide long-term continuous combustion treatment.

[0029] The method of use and working principle of the device: First, when the equipment is in use, the gas pipe 105 is threadedly connected between the outer wall of the gas interface 104, which can effectively transport the external combustion-supporting gas to the inside of the industrial furnace body 101. When the combustion-supporting gas is continuously discharged upward through the gas outlet 102, the combustion-supporting treatment of the fire can be completed. In the process of combustion of the combustion-supporting gas, the external compressor 212 can absorb the gas in the air into itself, and compress the gas inside the compressor 212. Subsequently, the low-temperature and low-pressure gas is compressed to form high-temperature and high-pressure gas, and the pipeline 211 is used as a transmission medium to transfer the gas to the inside of the gas treatment pipe 205. At the same time, a group of sliding blocks 209 slide Embedded in the sliding groove 208, the adsorbent plate 210 can be installed inside the gas treatment tube 205. When the heating plate 206 inside the gas treatment tube 205 is powered on, the current forms resistance in the heating plate 206 and generates temperature. This temperature can heat the gas treatment tube 205. Under a certain temperature and pressure, nitrogen will be adsorbed preferentially, while oxygen can flow out smoothly through the adsorber, thereby realizing the separation of oxygen and increasing the oxygen content in the output gas. The treated gas is drawn by the circulation pump 204 and uses the pipeline 1 203 as a drawer to transport the gas to the inside of the oxygen ring 201. Finally, the gas is ejected through a group of jet outlets 202 to complete the oxygen enrichment and combustion-supporting treatment of the burning flame.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
