Technical field

The utility model relates to a kind of vortex atomized fuel burner, belongs to improved environment-friendly and energy-efficient fuel oil atomizer burner technical field.

Background technology

Fuel oil is arranged to atmosphere by chimney in gas fume after burning.Its flue gas is flue dust, various waste gas by solia particle mainly, as sulphur and nitrogen oxide, also have hydrocarbon, carbon monoxide, carbon dioxide etc., they have formed the source of atmospheric pollution, and wherein most important reason is owing to the incomplete combustion of fuel oil causes.

The atomized fuel burner, be meant and utilize fuel oil under the forceful action of rotation at a high speed, make oil film breaking become superfine mist of oil, simultaneously again by means of revolving the auxiliary air premix of food tray outer rim to spray at a high speed, finish last atomizing, just can make fuel oil reach desirable combustion efficiency.Described auxiliary air is meant if root does not have air or air seldom, only inwardly spreads by the flame air outside, and then the hydrocarbon in the fuel oil can decompose, and produces carbon black.Carbon black is difficult to burning than gaseous fuel, if the lower or lack of air of flame terminal temperature, just cause that incomplete combustion causes the chimney over-emitting black exhaust easily, and after fuel oil sprays into burner hearth, be subjected to the radiation heating of flame and high-temperature flue gas, gasification rapidly, root from burner hearth covers sufficient auxiliary air again, just can make fuel oil completing combustion, just fuel savings greatly reduces the problem of atmosphere pollution.China Patent No. 02250133.9 discloses a kind of rotary cup ejection-type combustor, its secondary-atomizing oil is the interior oblique cone revolving cup of employing mainly, and oblique cone revolving cup complex structure in existence is provided with utilizes the interior oblique cone revolving cup of the direct drive of prime mover to rotate at a high speed, under high-temperature condition, the shortcoming that belt damages easily.

Summary of the invention

The purpose of this utility model is at the problems referred to above, provide a kind of need not be provided with revolving cup, simple in structure, easy for installation, safeguard easily, save cost, environmental protection and energy saving, durable vortex atomized fuel burner.

Operation principle of the present utility model, be utilize vortex that fuel oil is fully atomized before burning and make atomizing after fuel molecule and the abundant premix of air and reach completing combustion, reduce discharge of harmful gases simultaneously, reach energy saving purposes.

The purpose of this utility model is achieved in that the airduct road, tray for combustion, the oil pipe that comprise housing, be communicated with enclosure interior, revolve fixedly connected the revolving food tray, drive the drive unit that revolves the beam hanger rotation in beam hanger and top thereof; The Pan Bi of tray for combustion offers the venthole that is communicated with enclosure interior, revolve food tray and be arranged at the bottom of the combustion chamber in the tray for combustion, the drive unit that the beam hanger rotation is revolved in driving is the wind turbine whirligig, this wind turbine whirligig comprises turbine and turbine cover, turbine is fixedly connected on and revolves beam hanger, revolves beam hanger is installed on housing by bearing part inside; Venthole that tray for combustion is offered and the reverse vortex arranged of direction of rotation of revolving food tray.

The utility model, revolving beam hanger generally is to be installed on bearing sleeve by bearing part, bearing sleeve is installed on the inside of housing.

The utility model, oil pipe generally are to be installed on the inside of revolving beam hanger by bearing part.

The utility model revolves food tray and generally offers and get rid of oil groove.

The beneficial effects of the utility model: the oil inflame at existing oil burner is incomplete, produce a large amount of carbon blacks and pernicious gas, contaminated environment, the thermal efficiency and fractional energy savings are low, fuel-oil atmozation must be by adding the motor atomizer, volume is big, the cost height, weak points such as inconvenience are installed, the wind-force that makes full use of air blast directly drives the high speed rotation of vortex wheel, allow fuel oil before burning, reach desirable atomizing effect, make the fuel-oil atmozation poling tiny, uniform oil droplet, increase the surface area of fuel, reach burning fast, purpose of safety, simultaneously offer and revolve the venthole of the reverse vortex arranged of direction of rotation of food tray at the Pan Bi that revolves food tray, make fuel molecule after the atomizing and air abundant premix in proportion, and burning again after rapidly it being preheating to 300～500 ℃, make fuel oil obtain completing combustion, igniting is easily, thermal efficiency height, the fractional energy savings height, simple and fast is installed, easy to maintenance.

The utility model, have simple in structure, easy for installation, safeguard easily, save cost, environmental protection and energy saving, durable advantage.

Following embodiment accompanying drawings is further described the utility model.
