Abstract
The utility model belongs to an oil gas combustion device. A low-pressure secondary atomization combustion device of the utility model is composed of the cylinder body 3 of the combustion device, an air inlet pipe 2, an oil inlet pipe 1, an oil cylinder body 6, an oil cylinder cover 8, an oil cylinder bottom 4, and a stable combustion shield 5. The oil inlet pipe 1 is arranged on the bottom of the cylinder body 3 of the combustion device; the air inlet pipe 2 enters the cylinder body of the combustion device from the side surface of the cylinder body 3 in a tangential mode; the oil cylinder body 6, the oil cylinder cover 8 and the oil cylinder bottom 4 are arranged in the cylinder body 3 of the combustion device; the oil cylinder bottom 4 is provided with a slant air inlet hole 9; the oil cylinder body 6 is provided with an opening 7. The combustion device has simple structure, smokeless, low noise, combustion stability and high safety; the utility model has no blind firm or flame extinction no matter what size the flame is.
Description
The utility model belongs to diesel oil burner.
Liquid fuel combustion belongs to heterogeneous property diffusion combustion, because some liquid such as diesel oil burning-point are higher, can not light with fire under the normal temperature, therefore before burning, must carry out oil droplet cracking, atomizing, form one deck fuel-steam on the fuel oil surface, and burn simultaneously with after air mixes, in industrial furnace and food cooking stove, oil atomization and mix by burner with air and to realize will be so the supply mode of the structure of burner, shape, size, air dielectric will play decisive role to the liquid fuel combustion overall process.Major part is the low pressure atomising burner in the food cooking stove of public use at present, this burner generally is made up of burner cylindrical shell, blast pipe, joint oil pipe, vapo(u)rizing oil nozzle and interior rotary fluid, the joint oil pipe enters from the cylindrical shell side, blast pipe enters from the cylindrical shell bottom, be vertical between the two, the circular hole opening is arranged on the interior rotary fluid.Shortcomings such as this burner ubiquity that oil droplet atomizing is inhomogeneous, oil and air mixing velocity are slow, incomplete make combustion efficiency undesirable.
Chinese patent application CN 2211544 (application number 94223729.3) discloses a kind of " low-pressure air atomising burner ", form by burner cylindrical shell, blast pipe, joint oil pipe, vapo(u)rizing oil nozzle, interior rotary fluid and steady combustion cover, the joint oil pipe is positioned at burner cylindrical shell bottom, blast pipe tangentially enters the burner cylindrical shell from the cylindrical shell side, interior rotary fluid is arranged in the burner cylindrical shell, and special-shaped opening is arranged on it.Steady combustion covers on the vapo(u)rizing oil nozzle, and the top of steady combustion cover is taper blade, and every blade becomes the opening kiss on rotation a angle and the interior rotary fluid to connect.
The purpose of this utility model aims to provide the low pressure atomising burner that a kind of secondary-atomizing burns, noise is low.
Low pressure secondary-atomizing burner described in the utility model by burner cylindrical shell, blast pipe, oil inlet pipe, cylinder body, oil cylinder cover, oil cylinder at the bottom of and steady combustion cover form, oil inlet pipe is positioned at burner cylindrical shell bottom, blast pipe tangentially enters the burner cylindrical shell from the cylindrical shell side, be arranged in the burner cylindrical shell at the bottom of cylinder body, oil cylinder cover and the oil cylinder, oblique fresh air inlet is arranged at the bottom of the oil cylinder, opening is arranged on the cylinder body.
Its burner cylindrical shell of burner described in the utility model is through tangentially entering low-pressure air, air is turned clockwise along cylinder inboard wall, diesel oil is at the bottom of oil inlet pipe enters steady combustion cover and flows to oil cylinder, air inclined hole at the bottom of the oil cylinder tangentially directly blows primary atomization diesel combustion at the bottom of the oil cylinder, the clockwise spiral of diesel oil molecules of atomizing moves up, opening secondary-atomizing on cylinder body burning again, make burned flame form the short-flame torch of complete spray burning, uniform heating pot body has improved combustion temperature in hearth.
Burner structure described in the utility model is simple, and maintenance is convenient, and the diesel oil combustion gas is through twice atomizing, and smokeless, noise is low, flameholding, no matter large, medium and small fire is flame-out, and smouldering fire not, long service life, safe and reliable.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of cylinder body master of burner described in the utility model pseudosection.
Fig. 2 is the another kind of cylinder body master of a burner described in the utility model pseudosection.
Accompanying drawing can be as embodiment of the present utility model.Oil inlet pipe 1 enters from burner cylindrical shell 3 bottoms in the present embodiment, blast pipe 2 tangentially enters from cylindrical shell 3 sides, and 4 are arranged in cylindrical shell 3 after being connected at the bottom of cylinder body 6, oil cylinder cover 8 and the oil cylinder, perpendicular shape opening 7 is arranged on 6 at the bottom of the oil cylinder, also have auxiliary fresh air inlet 10 simultaneously, oblique fresh air inlet 9 is arranged on 4 at the bottom of the oil cylinder.Cylinder body 6 shown in Figure 1 is a upper big and bottom samll shape, and cylinder body 6 shown in Figure 2 is straight tubular.
