Description

  The present invention relates to a liquid fuel atomization cylinder, and more particularly to a liquid fuel atomization cylinder that is installed in a fuel supply pipe to a combustion apparatus to atomize the liquid fuel and improve combustion efficiency.

  In recent years, with the rise in crude oil prices, it has become an urgent task to reduce fuel consumption by improving combustion efficiency even a little in combustion apparatuses. Further, the reduction in the consumption of fossil fuels is also preferable from the viewpoint of environmental protection because it leads to a reduction in CO2 emissions, which is regarded as a cause of global warming.

As a measure to increase the thermal efficiency of heavy oil for boilers, etc., there is a method of passing a multifunctional catalyst in the middle of the fuel supply pipe to lower the molecular weight of carbon that is difficult to burn, and adding a function to make it easy to burn, and magnet and ceramic And far-infrared rays, thereby separating hydrocarbons finely and improving combustion efficiency. 3% to 10% water is mixed in heavy oil, emulsified and burned as emulsion fuel, and in sprayed oil droplets The water particles are rapidly vaporized depending on the temperature in the furnace, and the vaporized water vapor pulverizes the outer oil particles to further pulverize the surrounding oil and improve the mixing with the combustion air. In addition to the method of perfecting the combustion state, spraying fine wood powder and bark with an average particle size of 150 microns along with heavy oil to improve the combustion efficiency of the boiler and reducing the amount of heavy oil used, as well as the combustion air In the oxygen in the air to an activated state, a method of improving the combustion efficiency by feeding the combustion chamber. Has been proposed.
However, all of these have problems such as high cost, extra steps, and insufficient effects, and an efficient method has been demanded.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a liquid fuel atomization cylinder that can improve combustion efficiency only by attaching a simple device.

  In order to achieve the above object, the present invention is a liquid fuel atomization cylinder installed in a fuel supply pipe to a combustion apparatus, comprising a metal cylinder and a multi-spiral tube mounted inside the metal cylinder. The blade includes a joint portion between the blade and an external pipe at both ends of the metal cylinder.

  The present invention is also a liquid fuel atomization cylinder installed in a fuel supply pipe to a combustion device, wherein a double cylinder composed of a metal double pipe and an inner cylinder inside the metal double cylinder A multi-spiral blade mounted on the inner side of the double metal cylinder, a multi-spiral blade mounted on the outer peripheral portion of the inner cylinder of the metal double cylinder, and a joint between external pipes at both ends of the metal cylinder. Features.

  The metal cylinder and the metal double cylinder are made of stainless steel, and the multiple spiral blade is made of stainless steel or a combination of stainless steel and ceramics.

  The multi-spiral blade is pivotally supported in the metal cylinder, and the multi-spiral blade is rotated by the pressure of liquid fuel.

  A metal mesh member is installed at an end of the metal cylinder or double cylinder.

  According to the present invention, the molecular structure of the oil is refined by the spiral blade vortex generated by the spiral structure of the finely divided cylinder of the liquid fuel, thereby improving the oxygen bonding rate and bringing it into a state close to complete combustion. The effects of saving, reducing smoke and improving output are obtained.

  It is generally accepted that when the molecular structure of oil is linear, it is easy to burn, and when it is not linear, it is difficult to burn. When the molecular structure of the oil is linear, oxygen can be in uniform contact with the oil molecules, so there are few incomplete combustion parts of the oil. Since it cannot be contacted, incomplete combustion is likely to occur. Therefore, if the molecular structure of the oil can be made finer, the linear molecular structure will increase, and it will be possible to approach complete combustion.

As shown in FIGS. 2 and 3, the liquid fuel atomization cylinder according to the present invention has a triple spiral structure in the atomization cylinder, thereby generating a spiral blade vortex, and at the same time, the spiral flow An infinite number of ring-like vortices are generated around them, and these move together to create a dynamic liquid movement.
As a result, the molecular structure of the oil is refined and the oxygen bonding rate is improved to bring it into a state close to complete combustion, thereby achieving effects such as fuel economy, smoke reduction, and output improvement.
Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 6 is a diagram showing a situation in which a screw vortex is generated by the spiral blade 2 and a ring-shaped vortex is generated around the screw vortex. 3 is a cross-sectional view taken along the line AA in FIG.
As shown in FIG. 1, the fine granulation cylinder 10 is threaded at both ends so that it can be connected to external piping by screws. The fine-granulating cylinder 10 is also provided with a flange as shown in (b) and (c) so that it can be flange-coupled to external piping.

The liquid fuel atomization cylinder 10 shown in FIGS. 1 and 2 is a cylindrical member interposed in the liquid fuel piping facility, and spirals along the axis inside the exterior cylinder 1 through which the liquid fuel passes. A spiral blade 2 having a shape is provided. As shown in FIG. 3, the spiral blade 2 in this embodiment is formed by connecting three flat plates at the center and twisting them laterally with respect to the longitudinal direction of the outer tube 1. Thereby, the flow of the liquid fuel is divided into three and twisted to generate a vortex state in the liquid fuel.
FIG. 4 shows that the recessed portion 8 having an enlarged diameter is formed on the introduction side and the outlet side in the outer tube 1 so that the stainless steel mesh member 3 can be accommodated in the connecting portion when the connecting tube 4 is connected. However, the recess 8 and the stainless steel mesh member 3 may not be attached.

The spiral blade 2 is made of stainless steel. The liquid fuel becomes a vortex flowing along the spiral blade 2 while drawing a spiral. Moreover, it will also be in a turbulent flow state by accelerating the flow velocity. The liquid fuel thus swirled constantly collides with the spiral blade 2, so that the molecular structure is cut at the surface of the spiral blade 2. That is, only the surface portion of the liquid fuel flow is not in contact with the spiral blade 2, but is agitated, so that each portion of the liquid fuel flow is frequently replaced, and the molecular structure is cut by collision with stainless steel. The action extends to the entire liquid fuel.
When the stainless steel mesh member 3 is provided on the introduction side and the lead-out side in the outer tube 1 and liquid fuel is allowed to pass through, the molecular structure is cut by the contact action between the liquid fuel and the stainless steel mesh part. More effective.

It should be noted that four auxiliary plates 9 may be provided so as to be inclined by 60 degrees with respect to the spiral axis of the spiral blade 2 so that the flow of the liquid fuel is divided into six.

As described above, by providing the spiral spiral blade 2 along the axis of the outer cylinder 1, the liquid fuel flow path 7 is twisted. Such a spiral blade 2 is provided fixed to the outer cylinder 1, but may be supported by a bearing (not shown) so as to be able to rotate to the outer cylinder 1. Alternatively, a plurality of spiral blades (not shown) may be attached along the axis of the outer cylinder 1 so that they are rotated hydraulically.
In addition, plate-shaped small pieces are provided against the flow of the liquid fuel at arbitrary locations on the spiral blade 2 to generate a vortex in the small piece portion and to increase the twisting pitch of the spiral blade. Accordingly, it is possible to increase the collision frequency of the liquid fuel molecules by increasing the flow velocity of the liquid fuel and changing the laminar flow state of the liquid fuel to the turbulent flow state.
