Description

Description: TECHNICAL FIELD The present invention relates to a solidified fuel of liquefied gas that enables easy handling of liquefied petroleum gas and stable supply of vaporized gas, for example, portable gas. It can be used as fuel and gas lighter fuel.

(Prior Art) Conventionally, when liquefied petroleum gas containing butane and propane as main components is liquefied under pressure by its own vapor pressure in a sealed pressure vessel, stored and stored in a liquid state, and used as fuel, The fuel is taken out from the gas phase part of the fuel container as gas and burned, or the liquid is taken out from the liquid phase part and gasified and burned through a vaporizer.

However, depending on the method of use, the position of the liquefied petroleum gas fuel container cannot be kept constant, for example, a gas burner with a fuel container or a gas writer burns depending on the used position when the liquid liquefied petroleum gas flows into the nozzle and In some cases, inflow occurred, which significantly changed the combustion state.

As a measure against this, a tubular or porous suction core is provided to constantly supply the liquid to the nozzle section even if it is used in different positions in the fuel container, and it is gasified and burned by the vaporization mechanism near the nozzle valve. Was there.

(Problems to be Solved by the Invention) As described above, the conventional liquefied petroleum gas fuel has a feature that the liquefied petroleum gas is stored in a liquefied state and is a liquid.

In order to burn the liquefied petroleum gas, it is required to take it out as a gas from the nozzle crater, and it is easy to always take out the gas from the gas phase in a fixed storage container or a fuel container where the posture of use is constant. In particular, when using a device such as a gas burner with a fuel container or a gas lighter that is held by hand, the posture of use is not constant, and when the fuel is liquefied petroleum gas, when liquid is supplied to the nozzle valve and when gas is supplied. Then, the volume ratio of vaporized gas during combustion is about 1 for liquid.
The difference was 220, which caused a significant change in the formation of flames and became an important problem in terms of performance, and the danger was extremely high.

On the other hand, as in the gas writer, a tubular or porous suction core is provided in order to constantly supply the liquid to the nozzle portion even if the usage posture is different, or a porous material in the fuel container. The liquid of liquefied petroleum gas is adsorbed in this, but the one provided with a suction core is adapted to gasify the liquid supplied by the suction core through a decompression device or a vaporizer. A vaporizer for vaporizing a liquid in a small space near the nozzle of a cage gas writer must be constructed.Especially when a gas writer is used and many members are made of resin, heat conductivity is low. Poorly, the latent heat of vaporization necessary for vaporizing the liquid was not sufficiently supplied, and stable combustion could not be obtained at low temperatures or for long-term combustion, and the raw gas blowing phenomenon sometimes occurred.

Further, the structure as described above makes the structure complicated due to the suction core and the vaporizer mechanism, which causes an increase in processing and assembling costs as the number of members increases.

In view of the above points, the present invention provides a solidified fuel of liquefied petroleum gas that provides stable combustion, is highly safe, and can simplify the component configuration.

(Means for Solving the Problem) The present invention has been made to solve the above problems, and stearic acid or sodium stearate and butane are used in a fuel container having pressure resistance, such as a simple gas cylinder or a gas writer fuel container. After liquefied petroleum gas containing propane as a main component is sealed and heated, sodium stearate and butane and liquefied petroleum gas containing propane as a main component are melt-mixed and cooled and solidified in a pressure vessel to solidify the liquefied petroleum gas. As a fuel for chemical conversion.

(Operation) Since the solidified fuel of liquefied petroleum gas of the present invention is configured as described above, the state in which the liquefied petroleum gas is stored or accommodated in the pressure resistant container becomes a solid state, The surface layer of the solidified fuel is vaporized and vaporized, and the pressure vessel is filled with the solidified liquefied petroleum gas and the vaporized liquefied petroleum gas.

Therefore, the use attitude of the fuel container is not constant and the liquid of liquefied petroleum gas does not flow into the nozzle portion, and only the vaporized gas is always supplied to the nozzle portion.

Further, since the liquefied petroleum gas evaporates from the entire solidified surface layer portion, it is possible to stably supply the vaporized gas without partially concentrating the vaporization heat consumption, and to remove complicated vaporizer members. You can

(Example) Next, the Example of this invention is shown.

Example 1 A gas writer fuel container containing 0.7 parts by weight of stearic acid powder has airtightness and pressure resistance by a method such as ultrasonic welding, welding, and adhering a lid provided with a nozzle portion and a valve portion. So that the valve is opened from the nozzle provided on the lid and liquefied petroleum gas containing butane and propane as main components, preferably as isobutane 95% as a gas lighter
Liquefied petroleum gas or propane 10%, isobutane 30
%, 2.8 parts by weight of a mixed gas of 60% normal butane is pressurized to its own vapor pressure of liquefied petroleum gas or higher to fill and seal.

The fuel container in which the stearic acid and the liquefied petroleum gas are sealed is immersed in warm water or heated with hot air at 60 ° C while stirring until the stearic acid and the liquefied petroleum gas are melted and mixed, and then left to stand naturally. At room temperature or by forced cooling using a cooler or the like, the mixture of stearic acid and liquefied petroleum gas is completely solidified in the fuel container.

If the amount of stearic acid is 0.6 parts by weight or more with respect to 3 parts by weight of liquefied petroleum gas containing butane and propane as main components, complete solidification can be obtained.

Stearic acid content is 3 parts by weight of liquefied petroleum gas
If it is 0.55 parts by weight or less, precipitation is likely to occur during solidification, and if it is excessive, stirring during heating becomes difficult, which is not preferable.

Second Example In a fuel container having the same pressure resistance as in the first example, 0.8 parts by weight of sodium stearate and liquefied petroleum gas containing butane and propane as main components were sealed, and the fuel container was immersed in warm water, or Sodium stearate and liquefied petroleum gas are uniformly mixed while heated to 50 ° c to 60 ° c by warm air, and stirred by vibrating until it begins to gel, then cooled at room temperature or forcedly cooled by a cooler. This completely solidifies the mixture of sodium stearate and liquefied petroleum gas in the fuel container.

The liquefied petroleum gas solidified in the fuel container does not melt even if the fuel container is heated to 75 ° c again, and maintains a stable shape.

The blending amount of sodium stearate with respect to 3 parts by weight of liquefied petroleum gas containing butane and propane as main components is preferably 0.7 parts by weight to 1.3 parts by weight, and when it is 0.65 parts by weight or less, it is not completely solidified and easily becomes a gel state. If the amount is more than 1 part by weight, stirring is difficult during heating, which is not preferable.

The fuel container filled with the solidified liquefied petroleum gas shown in the first and second embodiments is used, and even if the container member is made of resin such as a gas lighter, the heating temperature is 60 ° C. For example, a time of about 5 minutes is sufficient, and liquefied petroleum gas
It has a vapor pressure of 60 ° c of about 9 kg / cm ² and can withstand pressure resistance sufficiently.

In the embodiment of the present invention, as a method of filling the fuel container with liquefied petroleum gas, a method of filling the fuel container with its own vapor pressure or a pressurized pressure has been shown, but as a method for filling the fuel container with liquefied petroleum gas, There is also a method of cooling the liquefied petroleum gas to a temperature equal to or lower than the boiling point and injecting and filling the liquefied gas whose vaporization is controlled, and the filling method is not limited.

Although the method of solidifying stearic acid or sodium stearate and liquefied petroleum gas in a device container such as a gas lighter is shown in the embodiment, stearic acid or sodium stearate is liquefied petroleum gas in another pressure resistant container. Then, after solidifying a large amount at a time, it may be boiled out at a place where vaporization is suppressed, for example, at a temperature lower than the boiling point of liquefied petroleum gas, cut into a desired size, and enclosed in a predetermined device. .

(Effects of the invention) As described above, since the present invention is a solidified fuel of liquefied petroleum gas, the liquefied petroleum gas solidified even in a portable fuel container such as a gas lighter or a fuel gas cylinder Evaporation is performed uniformly and stably from the layer surface.

Therefore, even if the usage posture is not constant, the liquid inside the container is solidified liquefied petroleum gas and vaporized liquefied petroleum gas. It will be supplied by the fuel, and it will be vaporized from the liquid surface by being stored in a liquid in the fuel container and vaporized from the entire surface layer of the solidified fuel compared to the vaporization structure near the valve part due to the suction core etc. Therefore, latent heat of vaporization is dispersed and a stable vaporization action is obtained, and stable combustion is obtained even when used at low temperature or for a long time.

Further, since only the vaporized gas is supplied to the nozzle portion, it is not necessary to provide a conventional complicated vaporization device, and it is possible to greatly reduce the number of parts and the number of assembling steps, and it is possible to significantly reduce the cost.
