Description

Technical Field

[0001] The utility model relates to the technical field of burner ignition gun equipment, in particular to a cyclically used natural gas burner ignition gun. Background Art

[0002] During the combustion process of the regenerative natural gas smelting furnace, the ignition gun needs to operate continuously according to the furnace conditions. During long-term operation, the high temperature causes the head of the combustion tube to expand and present a bell-shaped mouth. At this time, the flame of the bell-shaped combustion tube is diffused when burning, and the flame cannot be concentrated and ejected. The ignition gun is extinguished by the airflow of the burner. After the ignition gun combustion tube has a bell-shaped mouth, the operation is stable and the flame is extinguished. In order to ensure the continuous combustion state, the ignition gun needs to be replaced. Because the ignition gun combustion tube is tightly connected to the inner wall of the burner after the bell-shaped mouth appears, it cannot be removed. The ignition gun is removed by a destructive method, resulting in a waste of spare parts. In addition, the existing ignition gun head and the gun body gas source pipe are connected and welded with pipe threads. When replacing the combustion tube, cutting operations are required. During the operation, the gun head is damaged, causing the entire ignition gun to be scrapped. Utility Model Content

[0003] The utility model aims to provide a cyclically usable natural gas burner ignition gun to solve the above-mentioned problems.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses a circulating natural gas burner ignition gun, comprising a combustion tube and a gas source tube connected by a clamping assembly, a gun head is connected to the inner wall of the combustion tube, a main gas port is provided at the center of the gun head, a plurality of auxiliary gas ports are provided on the top outer wall of the gun head, an ignition electrode needle is installed on one side of the main gas port, a mixed gas source port is provided on the outer wall of the gas source tube, and the mixed gas source port is connected to the gun head through a hollow tube.

[0006] Furthermore, the clamping assembly includes a clamp locker, which is clamped on the outer side of the connection between the combustion tube and the gas source tube, and is fixed and locked by a locking bolt. A silicone sealing pad is provided on the inner wall of the clamp locker.

[0007] Furthermore, the gun head is a cyclone gun head.

[0008] Furthermore, the angle between two adjacent secondary air ports is 6°.

[0009] Furthermore, a UV sensor is provided inside the gas source pipe.

[0010] Compared with the prior art, the beneficial technical effects of the utility model are:

[0011] The utility model increases the number of auxiliary gas ports, increases the flow rate of the mixed gas, reduces the probability of ash blockage, and when the combustion tube of the ignition gun is damaged, only the combustion tube needs to be replaced and the replacement is fast without damaging the relevant parts of the gun body, and the gun head is not affected by the combustion tube or the gas source tube, so the position of the gun head remains unchanged.
