Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of burners, in particular to a flame-retardant burner for an incinerator. Background Technique
[0002] A burner is commonly known as a combustion device used on industrial fuel furnaces. It can be understood as a short name for a fire nozzle. Generally, it refers to the main body part of the combustion device, which has a fuel inlet, an air inlet, and a spray hole. Its function is to distribute fuel and combustion-supporting air and burn after spraying in a certain way. Some burners can control the output temperature by adjusting the heat output of combustion in certain ways. A burner can also be called a combustor, but it is different from the integrated combustor used on small boilers. Because they both belong to combustors, the concepts of the two are easily confused in production practice. The latter belongs to an integrated machine, generally also called a combustion engine, which integrates a combustion-supporting fan, fuel pressurization and conveying pipe fittings, and an ignition monitoring controller, and is applicable to small boilers and small fuel heating furnaces with a small number of spraying points. The former may include an ignition electrode and a flame monitoring probe, but a single burner generally does not include a combustion-supporting fan, fuel pressurization and conveying pipe fittings, and an ignition monitoring controller. The burner and the combustion-supporting fan, combustion-supporting air pipeline, fuel pressurization and conveying pipe fittings, and ignition monitoring controller need to be arranged according to the specific structure of different heating furnaces and the requirements of heating processes. The applicable field of the burner is wider than that of the integrated combustor.
[0003] However, it still has some disadvantages. For example, a general burner for an incinerator is just a fire nozzle that emits flames for operation. However, this may also cause the situation that the fuel remaining near the burner continues to burn after the burner is turned off, posing a safety risk, and the fire is likely to be further amplified.
[0004] To solve the above problems, a flame-retardant burner for an incinerator is proposed in this application. Content of the Utility Model

One side of the mounting plate is fixedly connected to the fuel inlet, one side of the mounting plate is fixedly connected to the air inlet, one side of the mounting plate is fixedly connected to the anti-backflow flame-retardant device. The anti-backflow flame-retardant device is convenient for, when the burner is performing a combustion operation, if flame backflow or the situation of unable to extinguish the flame occurs, after being detected by the flame detector, water mist is sprayed through the machine-controlled spraying port for emergency fire extinguishing to prevent the flame from spreading continuously and causing damage to the machine or the working environment.
[0007] Preferably, a plurality of screw fixing grooves are provided inside the mounting plate, the other side of the mounting plate is fixedly connected to the burner protection shell, an auxiliary heat dissipation port is provided on one side of the burner protection shell, and the metal outer water pipe is fixedly connected above the burner protection shell.
[0008] Preferably, the metal outer water pipe communicates with the anti-backflow flame retardant device, one side of the anti-backflow flame retardant device is fixedly connected to the water inlet, one side of the anti-backflow flame retardant device is fixedly connected to the water level indicator, and one side of the burner protection shell is fixedly connected to the burner protection ring.
[0009] Preferably, the flame detector is fixedly connected to the inside of the upper part of the burner protection ring, the machine-controlled spraying ports are fixedly connected to the inside of the burner protection ring, and there are a plurality of the machine-controlled spraying ports, and a flame spraying port is provided inside the burner protection ring.
[0010] Preferably, one side of the flame spraying port is fixedly connected to the burner main body, the burner main body is installed inside the burner protection shell, and one side of the metal outer water pipe is fixedly connected to the internal metal water pipe ring.

When the anti-backflow flame retardant device is operating, if the flame spraying port of the burner main body continues to burn after stopping operation, the flame detector receives an accidental signal, and the anti-backflow flame retardant device transfers the water inside to the machine-controlled spraying port through the metal outer water pipe, and finally opens through the machine-controlled valve to perform an emergency fire extinguishing operation on the flame spraying port to prevent the flame from spreading further.
