Description

Technical Field

[0001] The utility model relates to the technical field of combustion equipment, in particular to a novel fully sealed combustion nozzle structure. Background Art

[0002] In the existing burner design, there is a problem that the oxygen and combustible gas cannot be fully mixed. This incomplete mixing results in the combustible gas not being able to fully burn during the combustion process, which not only greatly reduces the energy utilization efficiency and greatly reduces the thermal efficiency of the combustion system, but also unburned combustible gas will be detected in the exhaust gas.

[0003] These unburned combustible gases not only waste precious energy, but also pollute the environment and increase greenhouse gas emissions. For these reasons, the environmental review of the combustion system is difficult to pass, which in turn affects the approval and implementation of the project. It is particularly important to further optimize the burner design and improve the mixing effect of oxygen and combustible gases. Utility Model Content

[0004] The purpose of the utility model is to provide a novel fully sealed combustion nozzle structure to solve the problem of insufficient mixing of oxygen and combustible gas proposed in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new fully sealed combustion nozzle structure, comprising a combustible gas inlet, which is connected to a nozzle cavity, and a long flame pipe is provided through the center of the nozzle cavity, an oxygen inlet is connected to the upper outer wall of the nozzle cavity, and roots of combustible gas combustion pipes are evenly distributed in the nozzle cavity.

[0006] Preferably, the head of the combustible gas combustion pipe is distributed with small holes, and the combustible gas is evenly distributed in the burner through the small holes.

[0007] Preferably, the burner cavity is provided with swirl plates evenly distributed around the circumference, which guide the oxygen-distributing air from direct flow to swirl flow.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] The utility model solves the problem that the oxygen supply and the combustible gas cannot be fully mixed by arranging a closed combustion nozzle structure. There are swirl plates with uniform circumference distribution in the nozzle cavity, which can guide the oxygen supply air from direct current to swirl, and after forced full mixing with the combustible gas, it enters the combustion furnace for combustion. The long-open flame pipe can ensure the stability of combustion, prevent the flame from being extinguished, improve the combustion efficiency, reduce the harmful substances produced by incomplete combustion, achieve a more environmentally friendly effect, improve the uniformity and stability of combustion, and enhance the overall thermal efficiency of the system.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0017] See also Figure 1-5 , an embodiment provided by the utility model:

[0018] A new type of fully enclosed combustion nozzle structure includes a combustible gas inlet 1, which is connected to the nozzle cavity 4, and a long flame pipe 3 is provided at the center of the nozzle cavity 4. An oxygen inlet 2 is connected to the upper outer wall of the nozzle cavity 4, and 6 combustible gas combustion pipes are evenly distributed in the nozzle cavity 4. Small holes are distributed at the heads of the combustible gas combustion pipes, and the combustible gas is evenly distributed in the nozzle through the small holes. There are swirl sheets with uniform circumferential distribution in the nozzle cavity 4, which guide the oxygen-matching air from direct current to swirl, and after forced and fully mixed with the combustible gas, enter the combustion furnace for combustion. The long flame pipe 3 can ensure the stability of combustion and prevent the flame from being extinguished.

[0019] Working principle: Fresh air is blown into the burner cavity 4 by a blower. Swirl blades are designed in this cavity. These blades can convert the direct air flow into swirl, thereby enhancing the mixing effect of the air. At the same time, the combustible gas is transported to the burner cavity 4 through a special combustible gas pipeline. These pipelines are evenly distributed in the cavity to ensure that the combustible gas can be fully mixed with the air in the entire cavity.

[0020] A notable feature of this design is that the air and combustible gas are forcibly and fully premixed before entering the combustion furnace. This premixing not only improves the combustion efficiency, but also significantly reduces the harmful substances produced by incomplete combustion, achieving a more environmentally friendly effect. After entering the combustion furnace, the mixed gas immediately burns to produce an efficient and stable flame.

[0021] The application of the new forced premixed combustion burner not only improves the uniformity and stability of combustion, but also effectively improves the overall thermal efficiency of the system.

[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
