Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a dual-control low-nitrogen and low-carbon monoxide burner. Background Art

[0002] Burner is a general term for a device that sprays 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 stainless steel and corrosion-resistant and high-temperature-resistant materials.

[0003] Although the existing burners can produce high temperatures during use, they are not equipped with a structure for adjusting gas delivery. Therefore, during the combustion process, the contact area between the gas and the space is fixed, making it impossible for the gas to be fully burned. This results in a large amount of residual air and a large amount of carbon monoxide, thereby reducing the combustion effect of the existing burner on the gas. For this reason, we propose a dual-control low-nitrogen and low-carbon monoxide burner. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a dual-control low-nitrogen and low-carbon monoxide burner having the advantages of good combustion effect, wide range of use, high environmental protection and high reliability, thus solving the problems raised by the above-mentioned background technology.

[0006] As a preferred technical solution of the utility model: the air outlet groove is located between the outer cover and the isolation tube three, and the distance between the sealing head and the top of the inner wall of the air outlet groove is 1 cm.

[0007] As a preferred technical solution of the utility model: the number of the air outlet holes 1 and the air outlet holes 2 are both six, and the six air outlet holes 1 and the air outlet holes 2 are evenly distributed along the top of the outer cover.

[0008] As a preferred technical solution of the utility model: the outer wall of the air inlet pipe 1 is fixedly equipped with a pipeline connector, and the outer wall of the pipeline connector is provided with a manual valve.

[0009] As a preferred technical solution of the utility model: an arc groove is formed on the outer wall of the outer cover, and the second air outlet is located at the bottom of the inner wall of the arc groove, and the interior of the shell is connected to the outside through the outer cover and the second air outlet.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The dual-control low-nitrogen and low-carbon monoxide burner, through the shell, outer cover, sealing head, air outlet hole 1, air outlet hole 2, air inlet pipe 1, and air inlet pipe 2 structures, allows the user to fully contact the gas with the air by adjusting the air inlet pipe 1 and the air inlet pipe 2 at different positions during the use of the burner, so that the gas is fully burned, the residual air and the output of carbon monoxide are reduced, and the combustion effect of the burner on the gas is improved.

[0013] 2. The dual-control low-nitrogen and low-carbon monoxide burner has an insulating tube 1, an insulating tube 2, an insulating tube 3, a positioning ring, and an air inlet pipe 1 structure. When the user has different usage requirements, the gas output can be reduced by adjusting the air inlet pipe 1 at different positions, so that the heat output inside the burner can be adjusted to different ranges. At the same time, the insulating tubes 1, 2, and 3 can separate the discharged gas to avoid the gas contacting the flame together or over a large area, resulting in unstable heat output, thereby improving the stability and reliability of the burner during operation. At the same time, the user can also use the internal structural design of the burner to realize the flue gas FIR circulation technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In a preferred embodiment, the air outlet groove 13 is located between the outer cover 2 and the insulating tube 3 17, and the distance between the sealing head 3 and the top of the inner wall of the air outlet groove 13 is 1 cm.

[0024] In the above structure, the exhaust gas is transported to the top of the fire head 11 through the exhaust groove 13 and the exhaust groove 13 structure, so that the gas can fully contact the flame and perform a cyclic combustion operation, so that the flue gas repeatedly contacts the flame and fully burns, thereby realizing the flue gas FIR circulation technology, and at the same time, the gas can be distributed at different positions, so that the combustion degree of the gas and oxygen can be adjusted, so that the temperature generated by the burner is different, so that the burner is suitable for different use environments, thereby improving the use range of the burner.

[0025] In a preferred embodiment, the number of the air outlet holes 1 5 and the number of the air outlet holes 2 6 are both six, and the six air outlet holes 1 5 and the six air outlet holes 2 6 are evenly distributed along the top of the outer cover 2 .

The application of the air duct 7 can ensure that the burner can be suitable for the design of circular or square pipes, further improving the scope of use of the burner.

[0033] Working principle: First, after the user assembles the burner, the gas can be transported through a square or round pipe. When the gas is transported through the connecting pipe 8, it is first transported through the main gas pipe 12. At this time, the gas will be discharged through the main gas pipe 12 to the intake pipe 2 10 and the intake pipe 1 9 with the manual valve opened. In this way, the gas is transported by pipes at different positions, thereby achieving the effect of gas diversion, increasing the contact area between the gas and the air, and thus improving the combustion effect of the burner on the gas, reducing the residual air and the production of carbon monoxide. During operation, the user can close the manual valves at different positions to reduce the gas transportation area inside the burner, thereby reducing the gas volume and the temperature output of the burner. It is suitable for different temperature requirements of users and thus increases the use area of ​​the burner.
