[0034] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it.

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 , before igniting the smelting furnace, the igniter needs to be checked to ensure the safety of ignition;

[0036] The ignition igniter is coal gas and combustion-supporting gas. When the combustion-supporting gas is used, it needs to be mixed with the coal gas, and after ignition, the problem of backfire needs to be avoided. When the existing igniter is used, a component to prevent backflow is used inside, such as a one-way valve, etc., but when used, it will affect the supply of coal gas, causing insufficient or discontinuous firepower. Based on this, the present application provides a smelting furnace ignition mechanism, including an ignition device 1 for igniting a smelting furnace and a Tesla valve 2 arranged inside the ignition device 1;

[0037] The ignition device 1 includes a connecting tube 12, both sides of which are provided with through holes and connected to the outer gas pipeline;

[0038] A gun barrel 13 is also provided on one side of the connecting tube 12, a thread groove 15 is provided on one end of the gun barrel 13, a nozzle 14 is provided on one end of the gun barrel 13 located at the thread groove 15, and an electric ignition component is provided inside the nozzle 14;

[0039] The inner side of the gun barrel 13 is adapted to the Tesla valve 2 , and an air passage 24 is provided inside the Tesla valve 2 for passage of gas.

[0040] First, connect the connecting tube 12 to the gas pipeline 16 of the smelting furnace. Then, install the barrel 13 on one side of the connecting tube 12, and ensure that the barrel 13 is adapted to the Tesla valve 2. Next, install the nozzle 14 on the threaded groove 15 of the barrel 13 to spray out the mixed coal gas and the combustion-supporting gas. An electric ignition component is installed on the inner side of the nozzle 14 to ignite the mixed gas. Finally, the mixed gas is introduced into the smelting furnace through the gas channel 24 provided by the Tesla valve 2 to achieve ignition.

[0041] The advantage of this smelting furnace ignition mechanism is that its structure is simple and easy to use, and through the design of the Tesla valve 2, the tempering problem is solved, and the continuity and stability of the ignition device 1 are improved.

[0042] The electric ignition assembly used above is one of the important parts of the ignition mechanism of the smelting furnace. Its function is to provide reliable electric spark ignition capability to ensure that the mixed gas can be ignited quickly and reliably. The electric ignition assembly is usually composed of an ignition electrode, a high voltage power supply and a control circuit.

[0043] The ignition electrode is the core component of the electric ignition assembly. It is responsible for generating a high-voltage electric field to generate an electric spark in the mixed gas to ignite the gas. The ignition electrode generally consists of two electrodes, a positive electrode and a negative electrode, between which a high-voltage discharge is generated. These electrodes are usually made of high-temperature and corrosion-resistant materials to cope with extreme working environments.

[0044] The high voltage power supply provides the required high voltage energy for the ignition electrode. The high voltage power supply usually adopts a transformer or a modular high voltage power supply module connected to the ignition electrode to provide enough electrical energy to generate a strong electric spark.

[0045] The control circuit is the intelligent part of the electric ignition component, which is responsible for monitoring the working state of the ignition device 1 and controlling the operation of the electric ignition component according to the set conditions and feedback signals. The control circuit usually detects key parameters such as temperature and pressure in the mixing area through sensors, and makes decisions based on these parameters to achieve automatic ignition control.

[0046] See also Figure 3 A mixing area is provided inside the connecting tube 12, and a mixing turbine 17 is provided in the middle of the mixing area for mixing the gas.

[0047] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 A handle 11 is provided at one end of the connecting tube 12 symmetrical to the gun barrel 13 to assist in carrying the connecting tube 12 .

[0048] A mixing area is provided inside the connecting tube 12, and the area is located in the middle of the connecting tube 12. The mixing area is designed to achieve mixing of coal gas and combustion-supporting gas to provide a mixed gas suitable for ignition. A mixing turbine 17 is provided in the middle of the mixing area, and the turbine fully mixes the coal gas and the combustion-supporting gas by means of rotation and impact. In this way, the uniformity and stability of the mixed gas can be ensured.

[0049] In addition, a handle 11 is provided at the symmetrical end of the connecting tube 12 (i.e., an end symmetrical to the gun barrel 13). The function of the handle 11 is to assist in carrying the connecting tube 12, so as to facilitate moving the ignition mechanism to a suitable position for ignition operation.

[0050] See also Figure 3 , Figure 6 , Figure 7 , Figure 8 as well as Fig. 9 The Tesla valve 2 further includes a shell 21 , a connecting ear 23 is provided on the outer side of the shell 21 , and one or more through holes are provided on the plate body of the connecting ear 23 for fixing the shell 21 .

[0051] Both ends of the housing 21 are provided with connecting through holes 22 , and one of the connecting through holes 22 is connected to the air outlet of the mixing area.

[0052] Another connecting through hole 22 of the housing 21 is adapted to the nozzle 14 for guiding out the injected mixed gas.

[0053] A pipe 16 is disposed inside the nozzle 14 , and one end of the pipe 16 is adapted to one of the connecting through holes 22 .

[0054] The design of the housing 21 takes into account the arrangement of the connecting ears 23, which are located on the outside of the housing 21. One or more through holes are provided on the plate body of the connecting ears 23 for fixing the housing 21 so that it can be stably installed in the ignition device 1.

[0055] In addition to the through holes, connecting through holes 22 are also provided at both ends of the housing 21. One of the connecting through holes 22 is connected to the gas outlet of the mixing area, so that the mixed gas can flow out smoothly through the Tesla valve 2. Such a design ensures the smooth transmission of the mixed gas and provides a suitable gas supply for ignition.

[0056] Another connecting hole 22 is located at the other end of the housing 21 and is adapted to the nozzle 14. Through this connecting hole 22, the nozzle 14 can be connected to the Tesla valve 2 to ensure that the mixed gas can be smoothly discharged. A pipe 16 is provided on the inner side of the nozzle 14, and one end of the pipe 16 is adapted to one of the connecting holes 22. Such a structural design ensures that the mixed gas flows from the Tesla valve 2 through the pipe 16, realizes precise orientation of the nozzle 14, and achieves the purpose of ignition.

[0057] In short, the design of the housing 21 of the Tesla valve 2 is very practical and flexible, and the smooth transmission and export of the mixed gas is achieved by combining the connection ear 23, the connection through hole 22 and the pipe 16. Through the synergistic effect of the Tesla valve 2, the smelting furnace ignition mechanism achieves efficient and stable ignition operation, improving the efficiency and safety of the smelting process.
