Abstract
The invention provides a burner nozzle which comprises an oil gun outer pipe, an oil gun inner pipe and an oil gun fixing sleeve pipe. One end of the oil gun fixing sleeve pipe is fixedly connected with a hollow fuel oil connector. The other end of the oil gun fixing sleeve pipe is connected with the oil gun outer pipe. A compressed air connector is arranged on the side face of the oil gun fixing sleeve pipe. A fuel oil guiding pipe is fixedly arranged on one side, close to the fuel oil connector, in the oil gun fixing sleeve pipe. The fuel oil guiding pipe is communicated with the fuel oil connector. The outer pipe wall of the fuel oil guiding pipe is in thread connection with the back end of the oil gun inner pipe. The front end of the oil gun inner pipe is connected with an oil spraying nozzle. The oil gun fixing sleeve pipe, the inner side of the oil gun outer pipe and the outer side of the oil gun outer pipe form an annular mixing cavity. An atomization oil spraying opening which is arranged opposite to the oil spraying nozzle is formed in the oil gun outer pipe. The burner nozzle is simple in structure, low in using cost and capable of improving fuel oil efficiency.
Description
Technical field
The invention belongs to burner technical field, especially relate to a kind of burner nozzle.
Background technology
Burner is the burner on industrial fuel stove, traditional fuel nozzle often adopts internal-mixing nozzle and outer mixed mode nozzle, internal-mixing nozzle adopts the spray orifice mechanical guide having certain angle, easily like this cause coking and block spray orifice and mixing chamber, in addition because it mixes in large internal mixing chamber then from the ejection of little spray orifice, so need very high air pressure and oil pressure, use cost is high, if oil pressure is lower than air pressure, spray orifice is blocked, and easily occurs that oil flows into the accident of air flue; Outer mixed mode nozzle, not easily block although atomization is good, but the mist of oil of ejection is mostly in coniform, combustion front is limited, and air feed adopts one direction air feed mostly, it is uneven that this makes mist of oil mix with air, and insufficient phenomenon of burning often occurs, and greatly reduces the efficiency of oil inflame and cause the waste of resource.
Summary of the invention
The object of the invention is to overcome prior art deficiency, providing a kind of structure simple, use cost is low and can improve the burner nozzle of fuel efficiency.
Technical scheme of the present invention is: a kind of burner nozzle, comprise oil gun outer tube, pipe and oil gun fixed sleeving in oil gun, described oil gun fixed sleeving one end is fixedly connected with the fuel joint of hollow, the other end connects oil gun outer tube, oil gun fixed sleeving side is provided with compressed air interface, fuel duct is fixedly installed in the inner close fuel joint side of described oil gun fixed sleeving, described fuel duct is connected with fuel joint, the outer tube wall of described fuel duct is threaded with pipe rear end in oil gun, in oil gun, the front end of pipe is connected with atomizer, the inner side of described oil gun fixed sleeving and oil gun outer tube and the outside of oil gun outer tube form the hybrid chamber of annular, described oil gun outer tube is provided with the atomization jet be oppositely arranged with atomizer.
Further, described oil gun outer tube is threaded with oil gun fixed sleeving.
Further, the diameter of described atomization jet is 2-4 times of atomizer diameter.
Further, the diameter of described atomizer is 1mm-2mm.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, structure of the present invention is simple, safe and convenient to use, the use of fuel oil can be saved again, more energy-conservation than traditional oil burner about 10%, by regulating oil pressure, air pressure, firepower control can be made within limits, thus reduce the consumption of fuel oil, reduce nitrogen oxide and soot emissions, make it to reach energy-conservation object on the basis ensureing normal productive life with this.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
Shown in sectional structure schematic diagram as of the present invention in Fig. 1, the invention provides a kind of burner nozzle, comprise pipe 2 and oil gun fixed sleeving 3 in oil gun outer tube 1, oil gun, described oil gun fixed sleeving 3 one end is fixedly connected with the fuel joint 4 of hollow, the other end connects oil gun outer tube 1, and described oil gun outer tube 1 is threaded with oil gun fixed sleeving 3.Oil gun fixed sleeving 3 side is provided with compressed air interface 5, fuel duct 6 is fixedly installed in inner close fuel joint 4 side of described oil gun fixed sleeving 3, described fuel duct 6 is connected with fuel joint 4, the outer tube wall of described fuel duct 6 is threaded with pipe in oil gun 2 rear end, in oil gun, the front end of pipe 2 is connected with atomizer 7, in the inner side of described oil gun fixed sleeving 3 and oil gun outer tube 1 and oil gun, the outside of pipe 2 forms the hybrid chamber 8 of annular, and described oil gun outer tube 1 is provided with the atomization jet 9 be oppositely arranged with atomizer 7.
The diameter of described atomization jet 9 is 2-4 times of atomizer 7 diameter, and the diameter of described atomizer 7 is 1mm-2mm.
The course of work of this example: when using invention to provide burner nozzle to carry out baker, first fuel joint 4 is communicated with fuel oil energy storage device, the air of pressurization is being imported by compressed air interface 5, due to oil gun fixed sleeving 3, in the inner side of oil gun outer tube 1 and oil gun, the outside of pipe 2 forms the hybrid chamber 8 of annular, thus make air fill up in the hybrid chamber 8 of annular, at this moment fuel oil is introduced by fuel joint 4, fuel oil is flow through by pipe in oil gun 2, spray through atomizer 7, mix with the forced air in hybrid chamber 8 after fuel oil is sprayed by atomizer 7, sprayed by atomization jet 9, complete the atomization process of fuel oil.Atomizer 7 is connected with pipe in oil gun 2 nose threads, the distance between flexible modulation atomizer 7 and atomization jet 9 can be carried out according to the negative pressure condition in hybrid chamber 8, at the compressed-air actuated pressure by regulating compressed air interface 5 to be communicated with, make the atomizing effect that fuel oil reaches best, improve the fuel efficiency of fuel oil, reach energy-conservation object.The diameter of atomization jet 9 is 2-4 times of atomizer 7 diameter, and the diameter of atomizer 7 is 1mm-2mm.Arranging different size to the nozzle diameter of atomizer 7 can according to the atomizer 7 of different fuel oil material matching different-diameter, to improve fuel efficiency further.
Because oil gun outer tube 1 is threaded with oil gun fixed sleeving 3, the outer tube wall of fuel duct 6 is threaded with pipe in oil gun 2 rear end, is convenient to clean pipe 2 in oil gun outer tube 1 and oil gun, raises the efficiency, can service life of prolonging combustion device nozzle.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
