Description

Light hydrocarbon fuel gasification device with anti-toppling function

Technical Field

The utility model relates to a light hydrocarbon fuel gasification equipment especially has the function of preventing empting and has better heat preservation and gasification efficiency to the light hydrocarbon fuel gasification equipment of function is prevented empting to utensil that has higher security.

Background

Among energy sources used in sanitary and bathroom facilities and kitchen gas facilities, natural gas and liquefied petroleum gas are most widely used.

The natural gas is mainly composed of methane and contains a small amount of ethane, propane and butane, and the liquefied petroleum gas is mainly composed of propane and butane. Such fuel gas is a gas at normal temperature and pressure.

When transporting natural gas, the natural gas can be transported through a laid pipeline directly from a supply source to a user's home or business location. However, not all buildings have a completely installed natural gas pipeline, and the gas is not easy to store and transport, so it is inconvenient to use. When transporting lpg, lpg manufacturers compress propane and butane into liquids under high pressure, store the liquids in cylinders, and transport the liquids to the user's processing or business.

However, the problems common to natural gas and liquefied petroleum gas are: first, fuel gas has a low molecular weight, and is accumulated in a space after being leaked, thereby easily causing gas explosion or fire; secondly, the liquefied petroleum gas utilizes the pressure difference between the high pressure in the steel cylinder and the external relatively low pressure to gasify the liquid fuel in the steel cylinder and output the gasified fuel to the combustion equipment (such as a water heater, a gas stove, etc.) for use; when the liquid fuel in the steel cylinder is used to a certain degree, and the vapor pressure in the steel cylinder and the external pressure tend to be balanced, the output of fuel gas is unstable, and the residual fuel cannot be used continuously, so that the problems of waste and the like are caused; thirdly, if the steel cylinder loaded with liquefied petroleum gas is accidentally dumped, the existing steel cylinder still can continuously supply gas in the steel cylinder after dumping because the existing steel cylinder has no anti-dumping equipment, and if a pipeline connected with the steel cylinder is damaged, leaked gas not only causes waste of the gas, but also easily causes potential risks such as gas explosion or fire; and fourthly, the steel cylinder is expensive in manufacturing cost, and if the structural strength of the high-pressure steel cylinder is insufficient, the risk of explosion is easily caused.

In the petrochemical industry, the main and high-price products extracted from crude oil are alcohol, gasoline and diesel oil, and the remaining low-price products are alkane, ether, alcohol, benzene and the like; the liquid alkanes with larger molecular weight are cheaper than natural gas and liquefied petroleum gas, the alkanes have the characteristics of no toxicity and high combustion value, and have the advantage of clean combustion products (H2O and CO2) compared with other petrochemical fuels, if the liquid alkanes can be used as fuel sources, the energy use cost can be reduced, and the environmental pollution can be reduced; however, since liquid alkanes are not easily vaporized, when combustion is incomplete, there is a risk of carbon monoxide poisoning. Therefore, in order to solve the problem that the liquid fuel is not easily vaporized, in the prior art, several vaporization apparatuses have been provided in an effort to reduce the unit price.

In the prior art, most of the liquid fuels are stored in a steel cylinder or other high pressure resistant container, high pressure air is injected into the liquid fuel in the steel cylinder or the container, and the fuel is converted into fuel gas for use through the assistance of a catalyst; however, since the bubbles need to be stirred uniformly by the stirrer to improve the gasification efficiency, a motor and fan blades are generally added; moreover, after the catalyst is used for a period of time, the catalyst needs to be replaced, and the complexity of the equipment and the maintenance cost of the equipment are relatively improved.

In addition, in order to improve the gasification efficiency, the injected air or liquid fuel needs to be heated, however, the heating effect is dispersed through the stirring effect; in the prior art, heating is also performed using a water jacket disposed around the vessel; however, since the water jacket is directly in contact with the external environment, a part of heat energy is lost to the external environment, and even in a low-temperature environment, the energy cost required for heating the water jacket is greatly increased to maintain the heating effect of the water jacket. There are also prior art efforts to improve fuel composition ratios, but reduce the convenience of using crude oil directly to fractionate the products.

Preferably, in the preferred embodiment of the present invention, the DC power connection port 24 of the light hydrocarbon fuel gasification device with anti-toppling function is configured to be connectable to DC 12V DC power; therefore, the direct current power supply device can be connected to direct current power supply equipment with the output voltage of DC 12V, such as a storage battery of an automobile, and is convenient for a user to use direct current as the power supply when power is off or outdoors besides using alternating current as the power supply when the user is at home.

The ac power input through the ac power port 23 and the DC power further reduced and rectified to a lower voltage through the transformer 23a, such as DC 12V, are all single voltages (such as DC 12V) regardless of the use of the DC power or the ac power, and the single operating voltage (such as DC 12V) is used for each electrical device in the device, so that the operating voltage of the electrical device can be consistent, and the safety of use can be improved by using the lower voltage DC power.

In the preferred embodiment of the present invention, the light hydrocarbon fuel gasification device with anti-toppling function can further be provided with an uninterruptible power system, which is located above the container body 1, and the current input from the ac power source and rectified by the voltage reduction of the transformer 23a or the current input from the dc power source is stored in the uninterruptible battery pack 21 of the uninterruptible power system, and each electrical device in the device uses the current provided from the uninterruptible battery pack 21, rather than directly from the external power source or the current directly from the transformer, so that even if there is no early warning power failure (such as power failure or power jump) or the power source is unstable, the power used by the device is the power stored through the uninterruptible power system, rather than the power which may be interrupted or unstable, so as to ensure that the light hydrocarbon fuel gasification device with anti-toppling function can maintain a good operation state.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the specification shall not be construed as limiting the scope of the claims concerned.
