Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 , an embodiment provided by the utility model:

[0022] An oxygen distribution heating and automatic cleaning burner device comprises a combustible gas inlet 1, a hot air inlet 2, a mixing box 3, a combustible gas nozzle 4 and a burner barrel 5. The hot air inlet 2 is provided on the outside of the combustible gas inlet 1, the mixing box 3 is provided on the outside of the combustible gas inlet 1, the combustible gas nozzle 4 is provided on the outside of the combustible gas inlet 1, the burner barrel 5 is provided below the combustible gas inlet 1, a nitrogen purge nozzle 7 is fixedly connected to the outside of the combustible gas inlet 1, a nitrogen injection mechanism 6 is fixedly connected to the outside of the nitrogen purge nozzle 7, and an air heat exchange mechanism 8 is fixedly connected above the hot air inlet 2.

[0023] Furthermore, a nitrogen injection pipe 601 is fixedly connected below the nitrogen injection mechanism 6 , and a nitrogen purge nozzle 7 is fixedly connected below the nitrogen injection pipe 601 , which can ensure the working operation time.

[0024] Furthermore, a fixing plate 802 is fixedly connected to the outside of the air heat exchange mechanism 8, a connecting ring 801 is fixedly connected to the outside of the air heat exchange mechanism 8, a connecting bracket 804 is fixedly connected to the inside of the connecting ring 801, a heat exchange cover 803 is fixedly connected to the top of the air heat exchange mechanism 8, and a heat exchange pipe 805 is fixedly connected to the bottom of the air heat exchange mechanism 8, which can improve the overall efficiency of the system.

[0025] Working principle: When using this device, combustible gas first enters the combustible gas circulation pipeline from the combustible gas inlet 1 and enters the mixing box 3 through the atomization effect of the combustible gas nozzle 4 at the end outlet of the pipeline. In order to achieve the atomization effect, a certain number of injection holes are opened on the end face of the combustible gas nozzle 4. Air enters the burner barrel 5 and enters the mixing box 3 through the hot air inlet 2. The combustible gas and air are mixed in the mixing box 3 and then sprayed out and ignited. Since this combustible gas is mainly composed of carbon monoxide, hydrogen, methane, carbon dioxide, nitrogen, water vapor and some high-molecular hydrocarbon gases and tar gas, wood vinegar gas, dust, etc., its calorific value is low. Since this gas contains a certain amount of non-combustible and non-flammable gases such as water vapor, carbon dioxide, nitrogen, tar gas, wood vinegar gas and a large amount of dust, this causes this combustible gas to have the characteristics of not being easy to ignite, low calorific value and instability, and easy sedimentation, adhesion and clogging of dust. The combustible gas enters the combustible gas circulation pipeline from the combustible gas inlet 1 and enters the mixing box 3 at the outlet of the end of the pipeline. The air heat exchange mechanism 8 heats the air and enters the combustible gas inlet 1 through the hot air inlet 2 and enters the mixing box 3. After the combustible gas and hot air are mixed in the mixing box 3, they are ejected through the combustible gas nozzle 4 and ignited. The preheated air can increase the flame temperature during the combustion process. A higher flame temperature helps accelerate the decomposition and oxidation reactions of the combustible gas, allowing it to burn more completely and thus improving the efficiency of heat energy release. After a long period of operation, the nitrogen injection mechanism 6 injects nitrogen at a regular and quantitative rate, and the nitrogen purge nozzle 7 purges the pipeline from the combustible gas inlet 1 to the combustible gas nozzle 4, thereby clearing dust and other deposits from the combustible gas pipeline.

[0026] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
