Background technique

Natural gas and liquefied petroleum gas are the most popular energy sources used in bathroom equipment and kitchen gas equipment. The main components are propane and butane. This type of fuel gas is a gas at normal temperature and pressure. Among them, natural gas can be directly transported from the supply source to the user's home or business place using the laid pipeline. However, not all buildings Everything has a well-equipped natural gas pipeline, and because the gas is not easy to store and transport, the liquefied petroleum gas industry uses high pressure to compress propane and butane into liquid, and stores it in steel cylinders, and then transports it to the user's processing or business place. for use. However, the common problem of natural gas and liquefied petroleum gas is that the molecular weight of the fuel gas is low, and it will accumulate in the space after gas leakage, which may easily cause a gas explosion or fire. In addition, the liquefied petroleum gas system uses the high pressure inside the cylinder to communicate The low-pressure pressure difference enables the liquid fuel in the cylinder to be vaporized and then exported to combustion equipment (such as water heaters, gas stoves, etc.) through pipelines. When the liquid fuel in the cylinder has been used to a certain extent, the vapor pressure in the cylinder will When it tends to balance with the external pressure, it will cause the output of fuel gas to be unstable, and the remaining fuel cannot continue to be used, resulting in waste and other problems. Moreover, the cost of the steel cylinder is expensive, and if the structural strength of the high-pressure steel cylinder is insufficient, it is easy to cause an explosion risks of.

In the petrochemical industry, the main and high-priced products of crude oil refining are alcohol, gasoline and diesel oil, and the remaining low-priced products are alkanes, ethers, alcohols, and benzenes. The price of liquefied petroleum gas is cheaper. Alkanes are non-toxic, high combustion value, and have the advantage of clean combustion products (H ₂ O, CO ₂ ) compared to other fossil fuels. If they can be used as fuel sources, they will be It can reduce the cost of energy use and reduce environmental pollution. However, because liquid alkane is not easy to gasify, it is easy to cause the risk of carbon monoxide poisoning due to incomplete combustion. Therefore, in order to solve the problem that liquid fuel is not easy to gasify, in the prior art, Several types of gasification equipment aiming at reducing the unit price are offered.

In the prior art, the liquid fuel is mostly stored in steel cylinders or other high-pressure containers, and high-pressure air is pumped into the liquid fuel in the steel cylinder or container, and with the assistance of a catalyst, the fuel is converted into gas for use. However, the injected air bubbles need to be stirred evenly by a stirrer to improve the gasification efficiency. Therefore, motors and fan blades must be installed, and the catalyst must be replaced after a period of use, which relatively increases the complexity of the equipment and the maintenance cost of the equipment. In addition, in order to improve the gasification efficiency, the injected air or liquid fuel must be heated, but the effect of heating will be dispersed through the stirring effect; in the prior art, a water jacket arranged around the container is also used However, since the water jacket is in direct contact with the external environment, part of the heat energy will be lost to the external environment, even in a low temperature environment, in order to maintain the heating effect of the water jacket, the energy required for heating the water jacket Costs will increase substantially. There are also previous technologies devoted to improving the fuel composition ratio, but the convenience of directly using crude oil fractionation products is reduced. Therefore, this new model hopes to provide a light hydrocarbon fuel gasification device that is convenient, simple in structure, and energy-saving, so as to improve users. Convenience of use, and reduce the equipment cost of the gasification device.
