とができる。[Detailed Description of the Invention] The present invention relates to a heavy oil atomization device that atomizes and burns heavy oil as a gas. Conventional external mixing type atomizers are capable of atomizing gas at relatively low pressure (1Kg/ cm2 or less), but they have the disadvantage of requiring a large amount of gas, and internal mixing type atomization devices have the disadvantage of requiring a large amount of gas. Although the oxidation equipment requires a small amount of gas, it requires relatively high pressure (2 to 3 kg/
cm 2 ). The present invention is designed to atomize at low pressure and with a small amount of gas. The details of the figure are as follows. Reference numeral 1 indicates a large number of spiral grooves 2 on the outer or inner periphery.
The atomizing medium nozzle 1 is inserted into the outer tube 3. Reference numeral 4 denotes an inner tube, and as shown in the figure, this inner tube 4 is arranged on a concentric axis at the center of the atomizing medium nozzle 1. At the tip of the inner tube 4, a large number of spiral swirl grooves 2' are formed on the outer periphery, and a swirl chamber 5 and an ejection hole 6 are formed on the downstream side thereof.
A liquid nozzle 7 is provided, and on the downstream side of the liquid nozzle 7 and the atomizing medium nozzle 1, a tip nozzle 8 is provided for controlling the ejection speed and spread of the liquid.
In such a configuration, the heavy oil introduced into the inner pipe 4 reaches the liquid nozzle 7, enters the swirl chamber 5 while being swirled and atomized by the large number of grooves 2' formed therein, and enters the swirl chamber 5, where it is The atomization is further promoted by the vortex generated by the vortex flow, and the atomization is ejected from the ejection hole 6 as a swirling flow. On the other hand, the gas introduced into the outer tube 3 reaches the atomizing medium nozzle 1 where it passes through a number of grooves 2.
It is ejected while being given a swirling flow. This jet stream of gas entrains and mixes the oil particles jetted out in a swirling flow from the jet hole 6, thereby further promoting atomization. The oil particles that have been sufficiently atomized and mixed with gas are ejected from the tip nozzle 8 portion.
By appropriately selecting the length and diameter of the tip nozzle 8, the ejection speed and spread angle of the mixture can be freely controlled, and a flexible flame shape can be obtained.
本考案は、以上の通り、第一段階の霧化を油の

良好な霧化を実行できる効果がある。 As described above, the present invention utilizes the pressure of oil to perform the first stage of atomization using the numerous grooves and swirl chambers of the liquid nozzle provided at the tip of the inner tube, and the second stage of atomization is performed using the swirling chamber. Since the atomization in the first stage is promoted by gas, the atomization progresses efficiently, and therefore good atomization can be carried out with a small amount of gas at low pressure.
