Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pure oxygen burners, in particular to a burner for a pure oxygen combustion system. Background Art
[0002] Burners are a general term for devices that spray fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application areas. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium.
[0003] The function of the burner is to atomize the sample through flame combustion. The atomized test solution enters the burner and, under the action of the flame temperature and flame atmosphere, undergoes processes such as drying, melting, evaporation, and dissociation to produce a large number of ground state atoms, as well as some excited state atoms, ions, and molecules.
[0004] The burner will produce smoke when burning, and the smoke contains carbon monoxide and water vapor, which needs to be treated before it can be discharged into the atmosphere. The existing burners are not effective when switching, so a large amount of carbon monoxide will be produced inside the burner. When the carbon monoxide exceeds the limit, an explosion will occur.

The recovered flue gas enters into the cylinder 1 through the top channel 13, and then is mixed with the gas and burned and sprayed out, so that the combustion temperature is reduced and the generation of nitrogen oxides is reduced. The recycling of flue gas can improve the stability of combustion. Through the coordinated use of the inner ring wiping gun 10 and the gas spray gun 3, the gas is sprayed evenly, which further improves the stability of combustion.
[0022] In a preferred embodiment, the bottom of the inner circle friction gun 10 is fixedly equipped with an inner circle annular gas pipe 11. There are six inner circle friction guns 10 in total, and the six inner circle friction guns 10 are evenly distributed on the fire basin brick 5. Through the setting of the inner circle annular gas pipe 11, the gas is filled into the inner circle annular gas pipe 11, and then the gas circulates in the inner circle annular gas pipe 11, and then gradually flows into the six inner circle friction guns 10, so that the gas is evenly distributed in the pre-combustion sleeve 6, thereby improving the stability of the device.
[0023] In a preferred embodiment, a pre-combustion sleeve 6 is fixedly installed on the top of the mounting bracket 2, and a plurality of inclined holes 61 are opened on the outer wall of the pre-combustion sleeve 6, and three inclined holes 61 are arranged vertically. Refractory bricks 7 are installed on the outer wall of the pre-combustion sleeve 6. By utilizing the setting of the pre-combustion sleeve 6, the flue gas and oxygen can intersect and mix at the center of the pre-combustion sleeve 6, and the flue gas can enter the center of the pre-combustion sleeve 6 through the inclined holes 61, thereby improving the rationality of the device.
[0024] In a preferred embodiment, the refractory bricks 7 are installed on the top of the cylinder 1, and the diameter of the top of the refractory bricks 7 is smaller than the diameter of the bottom. The setting of the refractory bricks 7 allows the flame to be ejected through the head of the refractory bricks 7. Since the temperature of the flame is relatively high, the refractory bricks 7 will not be affected by the high-temperature flame, so that the flame can be ejected regularly.
[0025] In a preferred embodiment, an outer ring annular gas pipe 9 is fixedly installed at the bottom of the outer ring rubbing gun 8. The outer ring rubbing gun 8 is located on the periphery of the refractory brick 7. There are six outer ring rubbing guns 8 in total, and the six outer ring rubbing guns 8 are evenly distributed. The inner ring annular gas pipe 11 is connected to the outer ring annular gas pipe 9 through a U-shaped pipe, so that the gas in the outer ring annular gas pipe 9 can enter the inner ring annular gas pipe 11 through the U-shaped pipe, so that the inner ring rubbing gun 10 can spray gas, thereby improving the rationality of the device.
[0026] In a preferred embodiment, the inner cavities of the bottom channel 14 and the top channel 13 are respectively installed with a bottom butterfly valve 16 and a top butterfly valve 15.

When air is needed, the top butterfly valve 15 is closed and the bottom butterfly valve 16 is opened. When smoke is needed, the top butterfly valve 15 is opened and the bottom butterfly valve 16 is closed, thereby improving the flexibility of the device.
[0027] Working principle: when in use, the gas pipeline is connected to the outer ring gas pipe 9, and then the gas in the outer ring gas pipe 9 enters the inner ring gas pipe 11 through the U-shaped pipe, and then the gas in the inner ring gas pipe 11 flows to the six inner ring rubbing guns 10 respectively, and the gas is sprayed into the pre-combustion sleeve 6 through the inner ring rubbing guns 10. At the same time, the air enters the pre-combustion sleeve 6 through the bottom channel 14 and the inclined hole 61 for mixed combustion, and then the flame is ejected from the refractory brick 7. The flame will produce smoke, and after being treated, the smoke returns to the pre-combustion sleeve 6 through the top channel 13 and the inclined hole 61 to mix with the gas for combustion, so that the smoke can be treated and the flame burns more intensely.
