Description

Technical Field

[0001] The utility model relates to the technical field of novel burners, in particular to a novel burner which is convenient for controlling the emission of nitrogen oxides. Background Art

[0002] A burner is a device that mixes air and fuel and then sprays them out for combustion. Usually, the burner is used to burn or heat materials in a certain space. After searching, it was found that the publication number in the existing public technology is: CN217763422U. A high-stability new burner device includes a shell, a nozzle, a fuel pipe, an air inlet and a fuel channel. One end of the shell is fixedly connected to the nozzle, and the other end of the shell is connected to the air inlet in the middle. Fuel channels are opened inside the side surfaces of the shell and the nozzle. An inner ring is embedded on the inner surface of the shell, and a paddle plate is fixedly set on the inner surface of the inner ring. The high-stability new burner device injects a high-speed airflow through the air inlet and accelerates it through the nozzle designed based on the Laval tube principle to form an ultra-high-speed flowing gas. The fuel channel is sprayed out by the ejection hole and mixed with the ultra-high-speed flowing gas. The ignition structure is set outside the nozzle, and the burner does not directly contact the flame, so that the burner will not be affected by the flame temperature to cause the surface temperature to increase, thereby extending the service life of the burner.

[0003] To sum up: the new burner installed in the above case is prone to produce nitrogen oxides during the combustion process, and nitrogen oxides are produced when fossil fuels and air burn at high temperatures. Therefore, the new burner installed in the above case cannot control the emission of nitrogen oxides, resulting in a large amount of nitrogen oxides being emitted into the environment, which is easy to increase environmental pollution. Utility Model Content

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a new burner that is easy to control nitrogen oxide emissions, so as to solve the problem that the new burner set in the above case proposed in the above background technology cannot control nitrogen oxide emissions, resulting in a large amount of nitrogen oxides being emitted into the environment, which easily increases environmental pollution.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of burner that is convenient for controlling the emission of nitrogen oxides, including a new type of burner structure, wherein an oil injection structure is provided inside the new type of burner structure;

[0006] The novel burner structure comprises a shell with a nozzle inside, a fuel pipe connected to the nozzle inside the shell, and an air intake pipe embedded at one end of the nozzle;

[0007] A mounting rod with an igniter at the bottom is installed on one side of the shell, and a smoke return hood is installed on the surface of the mounting rod, and a nitrogen oxide detection sensor module is installed inside the smoke return hood.

[0008] By adopting the above technical solution, the nitrogen oxide detection sensing module is set up to achieve sensing detection.

[0009] Preferably, fixing frames are installed inside the air intake pipe and the nozzle, and the fixing frames facilitate the installation of the injection structure components.

[0010] By adopting the above technical solution, the fixing frame is provided to achieve penetration and fixed installation.

[0011] Preferably, the oil injection structure comprises a connecting seat fixedly mounted on the fixing frame, and a cavity disk is rotatably mounted on one end of the connecting seat via a connecting bearing, and rotating blades are embedded and installed through the surface of the cavity disk.

[0012] By adopting the above technical solution, a fixed connection is achieved through the provided connecting seat.

[0013] Preferably, an injection head is embedded and installed on the surface of the rotating blade, the cavity disk is installed and connected to one end of the delivery pipe through a connecting bearing and a connecting seat, and the other end of the delivery pipe passes through the fixing frame and the intake pipe and extends to the outer wall of the intake pipe to be installed and connected to the fuel pipeline.

[0014] By adopting the above technical solution, the connecting bearing is provided to achieve a matching installation connection.

[0015] Preferably, the smoke return hood is made of high temperature resistant metal, and the smoke return hood is arranged in concentric circles.

[0016] By adopting the above technical solution, the smoke return hood is provided so as to achieve full combustion of the smoke return.

[0017] Preferably, there are three rotating blades, and the rotating blades are arranged in a ring array about the cavity disk.

[0018] By adopting the above technical solution, the provided rotating blades can drive the rotation adjustment.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the new burner is convenient for controlling the emission of nitrogen oxides.

[0020] (1) This case solves the problem that the new burner set in the above case cannot control the nitrogen oxide emission, resulting in a large amount of nitrogen oxide emission in the environment, which is easy to increase environmental pollution, by setting up: a smoke return hood and a nitrogen oxide detection sensing module in the new burner structure. When nitrogen oxides are generated during the combustion process, the nitrogen oxide detection sensing module detects the discharged nitrogen oxides. When the nitrogen oxide detection sensing module detects that the nitrogen oxide emission is high, the nitrogen oxide detection sensing module transmits the detection signal to the controller. At this time, the controller controls the fuel injection structure to work so as to fully burn the discharged nitrogen oxides and control the nitrogen oxide emission;

[0021] (2) By setting up: an oil injection structure, the above-mentioned problem is solved. When the glory pipeline transports the combustion oil to the inside of the cavity disk through the delivery pipe, the combustion oil is transported to the inside of the rotating blades and the injection head through the cavity disk to drive the rotating blades to rotate. At this time, the combustion oil injected by the injection head is mixed with air, nitrogen oxides and fuel and fully burned, thereby controlling the combustion of the emitted nitrogen oxides, and controlling the nitrogen oxide emissions by controlling the injection amount of the combustion oil.
