Description

Technical Field

[0001] The utility model relates to the technical field of chemical auxiliary equipment, and particularly relates to a burner. Background Art

[0002] A burner, as a key heat energy conversion device, realizes an efficient and clean combustion process by precisely controlling the mixing ratio of fuel and air.

[0003] In actual operation, maintaining an appropriate air supply is crucial for optimizing the combustion effect.

[0004] Insufficient air supply not only limits the completeness of the combustion reaction but also releases pollutants such as carbon monoxide and unburned hydrocarbons due to incomplete combustion. These residual substances can further react with atmospheric components, causing secondary pollution and seriously threatening environmental quality. On the contrary, although a high air flow rate can promote complete combustion, it will introduce too much cold air. This not only requires the combustion system to consume more energy to heat this additional air but also may lead to a decrease in the combustion temperature, affecting the thermal efficiency. At the same time, the presence of excessive oxygen may promote the formation of nitrogen oxides (NOx), which is also not conducive to meeting emission standards.

[0005] Therefore, how to adjust the air intake volume in the burner is an urgent problem to be solved. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a burner. When it is necessary to adjust the air intake volume, by driving the driving mechanism to drive the blocking piece to rotate, the blocking area of the blocking piece on the air inlet can be adjusted, thereby effectively controlling the air intake volume, making the fuel combustion more complete, and achieving the purpose of improving energy utilization rate, reducing energy consumption and environmental pollution.

[0033] Embodiment 1

[0034] This embodiment provides a burner, as Figures 1 - 8As shown in the figure, it includes a main body 1, a partition plate 2 and a damper assembly 8. A sealed cavity 3 is formed inside the main body 1; the partition plate 2 is arranged in the sealed cavity 3. A combustion chamber 31 is formed between one side wall of the partition plate 2 and the cavity wall of the sealed cavity 3. A feed pipe 4 and a pilot lamp 5 are penetrated through the side wall of the combustion chamber 31; a wind inlet chamber 32 is formed between the other side wall of the partition plate 2 and the cavity wall of the sealed cavity 3. An air inlet pipe is penetrated through the side wall of the wind inlet chamber 32. One end of the air inlet pipe is communicated with the combustion chamber 31, and the other end of the air inlet pipe is connected with an auxiliary combustion blower 11. An air inlet hole 61 is formed on the air inlet pipe; the air inlet hole 61 communicates the wind inlet chamber 32 and the air inlet pipe; an air inlet 7 is formed on the side wall of the wind inlet chamber 32; the damper assembly 8 includes a blocking piece 81 and a driving mechanism 82. The blocking piece 81 is arranged at the air inlet 7. Two ends of the blocking piece 81 are respectively rotatably connected to both sides of the air inlet 7. The blocking piece 81 is used to open or close the air inlet 7; the driving mechanism 82 is connected with the blocking piece 81, and the driving mechanism 82 is used to drive the blocking piece 81 to rotate.

[0035] Exemplarily, during implementation, the main body 1 is vertically arranged, and a sealed cavity 3 extending from the upper end of the main body 1 to the lower end of the main body 1 is formed inside the main body 1. A partition plate 2 is arranged in the sealed cavity 3. The partition plate 2 divides the sealed cavity 3 into a combustion chamber 31 located at the upper end of the main body 1 and a wind inlet chamber 32 located at the lower end of the main body 1. A feed pipe 4 and a pilot lamp 5 are penetrated through the side wall of the combustion chamber 31. Among them, the feed pipe 4 is used to convey fuel into the combustion chamber 31, and the pilot lamp 5 is used to ensure that the combustion chamber 31 always maintains a certain temperature, so as to achieve the purpose of facilitating the continuous ignition of the fuel, thereby improving the starting efficiency and stability of the burner.

[0036] The air inlet pipe is penetrated through the side wall of the wind inlet chamber 32. One end of the air inlet pipe extends upward and penetrates through the partition plate 2 to be communicated with the combustion chamber 31. The other end of the air inlet pipe is connected with an auxiliary combustion blower 11. An air inlet hole 61 is formed on the air inlet pipe to communicate the air inlet pipe with the combustion chamber 31.

On the one hand, the partition plate 2 divides the sealing chamber 3 into two parts, namely the combustion chamber 31 and the air inlet chamber 32, so that the fuel can burn more concentratedly and efficiently in the combustion chamber 31, and at the same time reduces the direct interference of the combustion process on the air inlet system. On the other hand, when it is necessary to adjust the air intake amount, the drive mechanism 82 drives the baffle 81 to rotate, so that the shielding area of the baffle 81 on the air inlet 7 can be adjusted, thereby effectively controlling the air intake amount, making the fuel burn more fully, and achieving the purpose of improving the energy utilization rate, reducing energy consumption and environmental pollution. On the other hand, the pilot lamp 5 ensures the continuity of combustion and reduces the risk of flameout, while the automatic adjustment function of the air damper assembly 8 can effectively prevent the combustion instability phenomenon caused by too large or too small air flow, improving the safety of the system operation.
