Description

Technical Field

[0001] This utility model relates to the technical field of venting ignition devices, specifically to a high-efficiency burner for venting ignition of converter gas. Background Technology

[0002] A burner, also known as a combustion nozzle, is a fuel combustion device used at the gas inlet of industrial combustion furnaces and chemical heating equipment. It is used to mix fuel with air and burn it, thereby providing heat for the heating process. It is widely used in various types of industrial kilns such as forging furnaces, natural gas kilns, gas-fired lime kilns, vertical kilns, and vertical shaft kilns, playing an important role in the heating process of industrial production.

[0003] A converter gas venting ignition device is a piece of equipment used to treat the gas generated during the converter steelmaking process. It is widely used in various fields such as petroleum, chemical, metallurgy, natural gas, coking, and coal chemical industries. In the steelmaking process, the converter produces a large amount of converter gas, a low-calorific-value gas. Direct emission without treatment would pollute the environment. The main function of the converter gas venting ignition device is to ensure safe operation during gas venting, preventing environmental pollution and safety issues. An effective ignition device can eliminate pollution to the surrounding environment from gas venting, while reducing ignition sources to ensure safe gas operation. Therefore, the selection and application of converter gas venting ignition burners are crucial for ensuring safe production and improving production efficiency.

[0004] Gas ignition is difficult due to various factors such as gas pressure, gas concentration, seasonal weather, extreme weather, and the ignition device itself. Furthermore, once ignited, it is prone to extinguishing, leading to ignition failure and the extinguishing of the persistent flame. Therefore, to address these issues, this invention provides a high-efficiency burner for converter gas venting ignition, solving the problem of persistent flame extinguishing during gas ignition in existing technologies. This not only affects production efficiency but may also pose safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency burner for converter gas venting and ignition, so as to solve the problem that the flame is easily extinguished during the gas ignition process under the existing technology.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a high-efficiency burner for converter gas venting and ignition, comprising a gas pipe, an inner circular burner detachably connected to the gas pipe, an outer circular burner fixedly sleeved on the inner circular burner, an exhaust seat provided on the inner circular burner, the exhaust seat having a cavity inside, an air inlet seat connected to the bottom of the exhaust seat, and several exhaust nozzles of varying lengths provided on the top of the exhaust seat.

[0007] The working principle of this utility model is as follows: When in use, first use bolts to fix the inner circle burner to the gas pipe, then adjust the exhaust nozzle to a suitable height according to the requirements, and then rotate the exhaust seat to make the outer convex ring of the circular ring rotate on the inner groove of the circular ring, thereby adjusting the exhaust nozzle to a suitable position, and the installation of the burner can be completed.

[0008] The beneficial effects of this utility model are as follows: By setting several exhaust nozzles of varying lengths, this utility model stabilizes the gas outlet flow rate and plays a decisive role in maintaining the flame of the gas ignition torch. This design provides flame protection for the ignition torch of converter gas venting and plays a key role in addressing the effects of gas pressure, gas concentration, seasonal weather, and extreme weather on gas ignition. It avoids the problem of the ignition torch going out easily during the gas ignition process under existing technology, which not only affects production efficiency but may also bring safety hazards.

[0009] Option 2, a preferred embodiment of the basic option, has an installation plate fixedly connected to the gas pipe, the installation plate having several first installation holes, and a docking plate fixedly connected to the inner burner, the docking plate having several second installation holes. The installation plate and the docking plate are connected by bolts through the first and second installation holes, facilitating the disassembly and assembly of the burner.

[0010] Option 3, a preferred option of the basic option, has several threaded holes on the top of the exhaust seat, several threaded cylinders are threadedly connected to the threaded holes, and threaded tubes are threadedly connected to the threaded cylinders. The threaded tubes and exhaust nozzles are fixedly connected; the height of the exhaust nozzles can be adjusted arbitrarily according to requirements.

[0011] Option 4, a preferred option of the basic option, has an outer convex ring on the outer wall of the exhaust seat and an inner groove on the inner wall of the inner burner. The outer convex ring slides on the inner groove, which facilitates the adjustment of the exhaust nozzle's installation position.

[0012] Option 5, which is a preferred option of the basic option, has several baffles on the inner wall of the outer circular burner. The baffles are arc-shaped and can regulate the airflow, thereby improving the combustion efficiency. Attached Figure Description
