Technical Field

[0001] The present invention relates to the technical field of burners, and in particular to a burner dedicated to a high-temperature pyrolysis furnace and a use method thereof. Background Art

[0002] The existing burner technical solution consists of two parts: an oil pump station and an oil supply pipe. The oil pump station consists of a pump, a relief valve, a filter, and a pressure gauge, which provide low-pressure fuel to the oil supply pipe. The oil supply pipe adopts a special pipeline design, which can timely control the output of fuel and compressed air. The gas and liquid interfaces are connected to the gas and oil sources through metal pipe flanges respectively. The fuel in the oil supply pipe is sprayed out in a mist through the nozzle of the ignition gun under the action of compressed air. The dispersed tiny oil droplets can burn quickly when encountering an open flame, thereby igniting and burning.

[0003] Disadvantages: The existing technology can only burn fuel oil, not combustible gas. Summary of the invention

[0004] The purpose of the present invention is to provide a burner dedicated to a high-temperature pyrolysis furnace and a method of using the burner in order to solve the above-mentioned problem.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: A special burner for a high-temperature pyrolysis furnace comprises a base plate, on which a fan is fixedly mounted, an output end of the fan is sealedly connected to an air duct, a combustion head is fixedly mounted on one side of the air duct, a fuel pipe and a gas pipe are inserted on the side of the air duct away from the combustion head, and a high-pressure water mist pipe is sealedly connected to the gas pipe; a high-pressure ignition package for igniting the position of the combustion head is also installed on the air duct, an ignition electrode and a fuel injector are arranged on the combustion head, the ignition electrode is electrically connected to the high-pressure ignition package, and the fuel pipe extends to the position of the fuel injector.

[0006] Preferably: a distribution box is fixedly installed on the base plate, and the distribution box is electrically connected to the fan and the high-voltage ignition pack respectively.

[0007] Preferably: a solenoid valve is fixedly installed on the base plate, the solenoid valve is electrically connected to the distribution box, and the gas pipe and the high-pressure water mist pipe are respectively connected to the external gas supply system and the external water supply system through the solenoid valve.

[0008] Preferably: the combustion head is also provided with an electric eye.

[0009] Preferably: a flame stabilizing disk is also provided on the burner head.

[0010] Preferably, the fuel pipe is connected to an external fuel supply system.

[0011] Preferably: universal self-locking wheels are fixedly mounted on the four corners of the lower surface of the base plate.

[0012] A method for using a special burner for a high-temperature pyrolysis furnace, characterized in that: using the above-mentioned special burner for a high-temperature pyrolysis furnace, comprising the following steps: Step S1: When the device receives the start signal, the program controller starts the entire system in the distribution box. The program controller first checks the status of each sensor (such as the electric eye), and after confirming safety, continues to execute the subsequent ignition program; Step S2: The fan starts to work and supplies air to the combustion head through the air duct. At the same time, the air door automatically adjusts the opening and closing degree according to the preset combustion optimization parameters to ensure that an appropriate amount of air is provided for combustion; Step S3: After confirming that the air volume and air flow are stable, the program controller will instruct the high-voltage ignition package to start working. The high-voltage electricity generated by the high-voltage ignition package is transmitted to the combustion head through the ignition electrode. At the same time, the fuel injector starts to spray oil and gas, and is ignited under the action of high-voltage electricity to form an initial flame; the electric eye monitors the flame state of the combustion head in real time. Once the flame is successfully ignited, the electric eye will send a current signal to the program controller to confirm that the combustion is normal. If the electric eye does not detect the flame, the program controller will immediately execute the fault shutdown program to ensure safety; Step S4: At the same time as step S3, the high-pressure water mist pipe on the gas pipe can also be turned on to start working, and the high-pressure water mist is sprayed into the combustion area. Under high temperature and high pressure conditions, water is cracked into hydrogen and oxygen, both of which can support combustion, thereby improving combustion efficiency, reducing carbon emission particles, and saving fuel; Step S5: During the entire combustion process, the program controller will continuously monitor various parameters (such as air volume, flame status, etc.) and make real-time adjustments as needed. At the same time, the solenoid valve will control the on and off of the gas pipe and the high-pressure water mist pipe according to the instructions of the program controller to ensure the stability of gas and water supply; Step S6: When the equipment receives a shutdown signal or reaches the preset shutdown condition, the program controller will execute the shutdown program. At this time, the fan continues to run for a period of time to cool the equipment and blow away residues. It can also supply water to the combustion head through a high-pressure water mist pipe for cooling. Then the entire system is shut down. Regular cleaning and maintenance of the equipment is also an important step to ensure long-term stable operation.

[0013] Preferably: in step S5, the ratio of direct current wind and swirl wind is adjusted by a flame stabilizing disk to ensure stable combustion of the flame, which helps to reduce the possibility of flame fluctuation and extinguishing and improve the stability and efficiency of combustion.
