Description

Industrial low-nitrogen type fuel oil burner Technical Field The utility model relates to the technical field of fuel oil burners, in particular to an industrial low-nitrogen fuel oil burner. Background The burner is a device for spraying fuel and air to mix and burn in a certain mode, combustion equipment such as a lighter, a gas stove and the like can be called as a burner, but in the industrial field, the burner generally refers to heating equipment for boiler bodies, kiln bodies and the like, the tail gas emission of the burner is important, and the low-nitrogen burner is a burner with lower nitrogen oxide content in tail gas after combustion, and compared with the common burner, the burner is more environment-friendly. The existing industrial low-nitrogen fuel burner is used for a long time, and due to the reasons of ageing of a pipeline, fuel production, contact with impurities in the transportation process and the like, some impurities possibly exist in fuel, a fuel filter element is usually arranged for avoiding the influence of the impurities on combustion, the fuel filter element needs to be replaced after being used for a period of time, the influence of blocking on fuel flow is avoided, a pipeline is required to be closed when the filter element is blocked, the continuous flow of fuel is avoided from leaking from the dismantling position of the filter element, the influence on the work of the burner is likely to be caused, for example, the time consumption before starting is prolonged, or the uniformity of heating is influenced by shutdown of the burner when equipment such as a boiler and a kiln are in operation. Disclosure of utility model Based on this, it is an object of the present utility model to provide an industrial low-nitrogen type fuel burner, which solves the technical problems mentioned in the background art. The industrial low-nitrogen type fuel oil burner comprises a burner main body, wherein an oil inlet of the burner main body is connected with a converging pipe, two sides of the outer surface of the converging pipe are connected with three-way pipes through first valves, one side of each of the two three-way pipes is connected with a fuel drain valve, the tops of the two three-way pipes are connected with a shell, the outer surfaces of the two shells are connected with an oil inlet pipe through second valves, the top of the shell is connected with a cover plate, the bottom of the cover plate is connected with a cylinder, the inside of the cylinder is connected with a fuel filter element, two sides of the cylinder are provided with filter holes, a collecting hopper and reinforcing ribs, a sealing gasket is connected between the shell and the cover plate, a limiting plate penetrates through the inside lower part of the shell, a framework is fixed at the top of the limiting plate, and a sealing ring is sleeved outside the framework.
