Abstract
The utility model relates to a low pressure atomizing oil combustion gun used for the ignition and the combustion suppor of industrial furnaces and the thermal power generation, composed of a spray head, an atomizing chamber casing, a gun body, an atomizing choke, a back cover, an air inlet pipe, an oil inlet pipe, etc. A plurality of spray orifices are arranged on the spray head; an oil inlet and a plurality of air inlet are arranged on the atomizing choke; the front end of the choke present an atrumpet mouth shape, the bottom is communicated with the air inlets and the oil inlet, and the mouth is connected with the atomizing chamber. The utility model adopts a low pressure choke atomizing principle that oil at the front part and air at the back part are mixed inside to make oil be burnt sufficiently, has the advantages of simple structure, high safety and energy saving and overcomes the defects brought by using high pressure atomizing medium.
Description
The utility model belongs to oil burning installation, relates in particular to the low pressure atomizing fuel gun.
The igniting of present various Industrial Stoves and firepower power station, steady combustion, combustion-supporting employed oil combustion gun generally all adopt the high-pressure atomization supply mode, the desired safety coefficient of high voltage supply is very high, be difficult to satisfy field requirement, and on-the-spot no high pressure facility person can't use.In addition, the high-pressure atomization poor effect, oil inflame is insufficient, and energy waste is bigger.
The purpose of this utility model is to provide a kind of atomizing effect good, can make full use of the low pressure atomizing fuel gun that low-pressure gas source is done atomizing medium.
The utility model is to realize like this, this oil combustion gun is mainly by shower nozzle, the spray chamber shell, the rifle body, bonnet, air inlet pipe and oil inlet pipe are formed, the atomizing trunnion is positioned at the rear portion of spray chamber shell, along a fuel feed hole is arranged on the longitudinal center line of this trunnion, several and its at an angle air admission hole is arranged around fuel feed hole, the outlet of air admission hole is at the rear side of fuel feed hole outlet, the front end of this trunnion is bell mouth shape, its bottom communicates with fuel feed hole and air admission hole, oral area links to each other with spray chamber, the front portion of shower nozzle is hemispherical, be furnished with several become certain angle of inclination with axis spray orifice, air inlet pipe is connected on the rifle body, and the rifle body is connected with bonnet, and oil inlet pipe is connected on the rear end of atomizing trunnion.Shower nozzle and rifle body are fixed on the forward and backward two ends of spray chamber shell respectively by screw thread, the atomizing trunnion outer surface have one the circle flange, be pressed abd fixed in the spray chamber shell by the rifle body.
The utility model adopts the interior mixed atomizing principles behind the gas before low pressure, the wikipedia type oil, various fuel oils is fully burned having under the conditions such as compressed air, steam, air blast, and eliminates black smoke.The utility model is simple in structure, easy and simple to handle, safe in utilization, good energy-conserving effect, has overcome all drawbacks of using the high-pressure atomization medium to be brought.
Accompanying drawing 1 is the side view cutaway drawing of the utility model oil combustion gun.
Accompanying drawing 2 is the enlarged diagram of the utility model oil combustion gun shower nozzle.
The utility model oil combustion gun is further described by embodiment below in conjunction with accompanying drawing.
From accompanying drawing 1, can see that the utility model oil combustion gun mainly is made up of shower nozzle 2, spray chamber shell 3, rifle body 8, atomizing trunnion 5, bonnet 11, oil inlet pipe 10 and air inlet pipe 9.The front end of shower nozzle 2 is hemispherical, and be furnished with a plurality of spray orifices 1 that become certain angle of inclination with axis, spray orifice 1 is a funnel-form, the rear end of shower nozzle 2 is connected by the external screw thread of internal thread with spray chamber shell 3 front ends, rifle body 8 is connected by the internal thread of external screw thread with spray chamber shell 3 rear ends, air inlet pipe 9 is connected on the rifle body 8, and rifle body 8 is threaded with bonnet 11 usefulness.Be equipped with an atomizing trunnion 5 at the rear portion of spray chamber shell 3, the external diameter of this trunnion 5 is slightly smaller than the internal diameter of spray chamber shell 3, outer surface at trunnion 5 has a circle flange 4, be used for being stuck in the internal thread groove of spray chamber shell 3 rear ends, the threaded engagement by spray chamber shell 3 and rifle body 8 is fixed trunnion 5.The rear end of trunnion 5 links to each other with oil inlet pipe 10 with screw thread, along opening a fuel feed hole 7 on the longitudinal center line of trunnion 5, fuel feed hole 7 is a funnel-form, several and its at an angle air admission hole 6 is arranged around fuel feed hole 7, be funnel-form, the outlet of air admission hole 6 is positioned at the rear side of the outlet of fuel feed hole 7, and aims at its outlet.The front end of atomizing trunnion 5 is bell mouth shape, and opening degree is 50 degree, and bell-mouthed peristome also is that spray chamber links to each other with the inner chamber of spray chamber shell 3, and its bottom communicates with fuel feed hole 7 and air admission hole 6.Like this, gas enters ring thorax in the rifle body 8 from air inlet pipe 9, enters horn mouth by air admission hole 6, and fuel oil enters horn mouth from oil inlet pipe 10 by fuel feed hole 7.Because the flow velocity of air-flow is greater than the flow velocity of oil stream, and blow oil back to front by a plurality of directions, the mode of utilizing air-flow to shear makes oil atomization, through after mixing in the spray chamber, by spray orifice 1 ejection, oil plant is fully burned then.The quantity of spray orifice 1, aperture size and angle of inclination thereof increase and decrease with the viscosity size of used fuel oil, and viscosity is big more, and its quantity and aperture size are wanted corresponding increase, and corresponding reducing wanted at the angle of inclination.Present embodiment is with regard to residual oil and diesel oil, and establishing spray orifice 1 is 13, and the aperture is 1-2.5mm, except that middle hole along axis is offered, remaining spray orifice all becomes 45-55 degree angle vertically with axis, and along clockwise inclination 25-35 degree, be circumferential and equidistantly distribute, see also accompanying drawing 2.Because the viscosity of residual oil than diesel oil more greatly, so its aperture size should be got bigger value, angle is then got less value.The aperture of present embodiment fuel feed hole 7 is 1.5-3.0mm, can be according to the corresponding increase and decrease of the Capability Requirement of oil combustion gun, and the design maximum ability of this oil combustion gun is 300 kilograms/hour, air admission hole 6 is established 6-10, be circumferential and equidistantly distribute, its aperture is 2.0-2.5mm, becomes 50-60 degree angle vertically with axis.The quantity of air admission hole, aperture size and angle also should be adjusted accordingly according to the viscosity of used fuel oil as spray orifice 1.The utility model oil combustion gun can make full use of low-pressure gas source and do atomizing medium, as compressed air, steam, air blast, air inducing etc., uses 0.05-0.3 MPa low pressure, and as oil pressure 0.2, then air pressure 0.25.This oil combustion gun is applicable to igniting, the steady combustion, combustion-supporting of various industrial furnaces such as chemical metallurgy, thermal power generation, and residual oil, cracked residue, heavy oil, diesel oil etc. can burn.
