Compared with the prior art, the atomizing oil gun can achieve ideal atomization granularity, enables the fuel oil to be burned completely, enables cooling furnace heavy residual oil to achieve direct-fire, reduces the phenomena of coking and blockage of the oil gun, avoids the problems that oil drops which are imperfectly combusted directly influences running of relative corollary equipment, enables the fuel oil to reach the requirements of efficient and complete combustion, energy conservation, and emission reduction, and then guarantees normal temperature rise and technological requirements of heating equipment, and at the same time, does not need to increase fuel-injection quantity, lowers production and use cost, decreases waste of energy sources, and lowers pollution.
Description
Technical field
The utility model relates to a kind of atomized oil gun, and specifically a kind of Double spiral-flow atomising oil gun belongs to the fuel oil burner technical field.
Background technology
In the prior art, fuel oil burner mainly is comprised of fuel oil burner (being oil gun) and air register two large divisions.Fuel oil sprays in the stove after oil gun is atomized into tiny oil mist particles by oil inlet pipe and burns, and air register provides the burning required air.For fuel oil can fully be burnt, must improve the atomization quality of fuel oil, and mist of oil and combustion air are fully mixed, form good combustion air aerodynamic field.Be not difficult to find out, atomization quality and mixed flow regime are the principal elements that affects oil firing.
The widely used oil gun of China's oil burner mainly is divided into the oil gun of the single atomizing principles work of mechanical atomization and medium (steam or compressed air) atomizing two large classes at present.Because the principle that this two classes oil gun itself exists and the defective of structure, and the inferior quality of China's fuel oil, so that this two classes oil gun ubiquity atomized particle size is large, incomplete combustion, the heavy residual oil direct-fire difficulty of black furnace, the coking of oil gun, stop up seriously, imperfect combustion oil droplet directly affect the problems such as relevant corollary equipment operation, can't reach efficient abundant the burning and the requirement of energy-saving and emission-reduction.Because the oil gun atomization quality is not high, fuel oil combustion is insufficient, and for guaranteeing normal temperature rise and the technological requirement with hot equipment, enterprise has to increase distributive value, has directly increased production and the use cost of enterprise, causes energy waste, and pollutant discharge amount increases.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of Double spiral-flow atomising oil gun, basic goal is that solution oil gun atomized particle size is large, incomplete combustion, the heavy residual oil direct-fire difficulty of black furnace, the coking of oil gun, stop up serious, imperfect combustion oil droplet directly affects the problem of relevant corollary equipment operation, make fuel oil reach the requirement of efficient fully burning and energy-saving and emission-reduction, when then guaranteeing aborning with the normal temperature rise of hot equipment and technological requirement, distributive value be need not increase, production and use cost reduced, reduce the waste of the energy, reduce and pollute.
To achieve these goals, the utility model comprises by base and the fixing cyclonic current device that is used for consisting of the oil gun main body, atomizer, minute food tray, outer tube and the inner sleeve of flange, cyclonic current device, atomizer and be connected food tray to connect successively, be provided with the cyclonic current blade in cyclonic current device inside, atomizer inside is provided with the atomizer blade, outer tube is connected with the gas joint, inner sleeve is connected with oily joint, cyclonic current device and atomizer are equipped with the inclined-plane divided edge structure, the cyclonic current blade is opposite with the direction of rotation of atomizer blade, is provided with backflash in minute food tray.
The cyclonic current device passes through cushion seals.
The atomizer blade has three at least.
The cyclonic current blade has six at least.
Compared with prior art, this atomized oil gun carries out Double spiral-flow atomising by the opposite cyclonic current device of direction of rotation and atomizer to fuel oil mode, the atomized particle size that can realize ideal, make the fuel oil can completing combustion, make the heavy residual oil of black furnace realize direct-fire, reduced the coking of oil gun, clogging, avoided imperfect combustion oil droplet directly to affect the problem of relevant corollary equipment operation, make fuel oil reach the requirement of efficient fully burning and energy-saving and emission-reduction, when then guaranteeing aborning with the normal temperature rise of hot equipment and technological requirement, distributive value be need not increase, production and use cost reduced, reduce the waste of the energy, reduced pollution.
