[0027] Please refer to Figures 1-6 , the present utility model provides a technical solution for an air - atomized waste oil incineration oil gun: An air - atomized waste oil incineration oil gun includes an incineration oil gun main body 1. An outer pipe body and an inner oil pipe are arranged on the incineration oil gun main body 1. A nozzle 2 is connected to the outlet end of the inner oil pipe. A docking pipe fitting 3 for guiding air and oil is connected to the outlet end of the outer pipe body. A mixed gas spray head 4 is fixedly connected to the outlet end of the docking pipe fitting 3. The inner and outer parts at the outlet of the mixed gas spray head 4 are narrowed towards the center. A mixing mechanism 5 conducive to the mixing of oil and gas is arranged in the inner cavity of the mixed gas spray head 4. A diffuser 6 fixedly connected to the mixing mechanism 5 is inserted into the outlet end of the mixed gas spray head 4; Introducing air from outside the inner oil pipe has two functions: one is to atomize the waste oil. The other is to cool the inner oil pipe, and it can also prevent the waste oil from caking and blocking the nozzle in the oil gun.

[0028] Furthermore, the nozzle 2 includes a nozzle pipe 21. A nozzle opening 22 that is narrowed both inside and outside is arranged at the outlet of the nozzle pipe 21. No swirler is added inside the nozzle 2 to make the waste oil passage smoother. At the same time, the length of the nozzle spray opening is increased to prevent backfire.

[0029] Further, the docking pipe fitting 3 includes a pipe fitting main body 31 that is hermetically connected to the outer pipe body. A central hole 32 for screwing and fixing with the oil nozzle 2 is provided at the center of the pipe fitting main body 31. Ventilation holes 33 are provided in the pipe fitting main body 31 in a circumferentially arranged manner outside the central hole 32. The outlet ends of the central hole 32 and the ventilation holes 33 communicate inside the pipe fitting main body 31. A hollow connector 34 is provided at the right end of the pipe fitting main body 31.

[0030] Further, the mixing mechanism 5 includes a circular ring block 51. A cylinder 52 is sleeved and fixed on the outside of the circular ring block 51. Mixing ports 53 are evenly provided in the inner cavity of the cylinder 52. The mixing mechanism 5 is added behind the oil nozzle, and air and waste oil are premixed evenly in advance.

[0031] Further, the diffuser 6 includes a connecting rod 61 screwed to the central hole of the circular ring block 51. A diffuser head 62 with a conical surface extending outward to the right is fixedly connected to the right end of the connecting rod 61. An adjustable diffuser is added to the gun head, and the flame length can be adjusted according to needs, so as not to wash the boiler water-cooled wall tubes.

[0032] Further, a positioning nut 7 located on the left side of the circular ring block 51 is screwed to the left end of the diffuser 6.

[0033] A specific application of this embodiment is as follows: This air atomized waste oil incineration oil gun is used in conjunction with a gas boiler burner. Its principle is that the waste oil containing particulate impurities (mainly composed of C3, C4, and C5) produced by propane dehydrogenation is premixed with air and then sprayed out at a certain angle through an adjustable diffuser, and burns after encountering the central flame of the burner; the insufficient air part is supplemented by the hot air from the burner air box, so that its combustion state neither emits black smoke nor burns fully (re-burns when encountering the burnout air in the upper part of the furnace), avoiding excessive nitrogen oxides caused by too high flame center temperature. The flame length must be controlled to be less than 5 meters so as not to wash the boiler water-cooled wall. The flame center temperature is controlled to be less than 1000 °C, and the flame color is preferably light red;

[0034] The following is the safety operation procedure for this air atomized waste oil incineration oil gun:

[0035] 1. The oil gun must be put into operation only under the premise that the burner is in operation.

[0036] 2. When normally putting the oil gun into operation, first turn on the compressed air, and then turn on the fuel valve. There must be someone on site to operate and observe the flame situation for timely adjustment.

[0037] 3. When stopping the oil gun, first close the two manual valves of the fuel quick closing valve and then the compressed air valve. Then use nitrogen to displace the fuel pipeline for more than 3 minutes. Then close the manual fuel valve.

[0038] 4. The normal fuel pressure is preferably 0.5 MPa (G), and the compressed air is 0.7 MPa (G).

[0039] 5. When the boiler trips automatically or manually, the main fuel valve shall be closed simultaneously.

[0040] 6. A check valve shall be installed after the fuel quick - closing valve and the main pipe of the compressed air branch pipe, or other measures shall be taken to prevent air cross - leakage.

[0041] 7. When the oil gun is not in use, compressed air shall be constantly introduced to cool the oil gun.
