Description

Fuel supply safety device

The present invention relates to a fuel supply safety device, in particular to a liquid fuel gasification process, which uses the heating device to mix air and gaseous fuel with the air refiner and heat it to prevent the gas fuel from leaking and sinking. The purpose of hoarding security.

According to the general use of heating fuel in households, the use of liquefied petroleum gas or natural gas is convenient and safe to use. Therefore, it is widely used in human life. Natural gas and liquefied petroleum gas are mainly produced from oil fields or natural gas fields. The organism also emits methane, which only produces carbon dioxide and water after combustion. It is a less polluting energy source. In recent years, it has gradually changed the fuel of thermal power plants to natural gas to reduce air pollution. The main component is methane (CH4), methane is the shortest and lightest hydrocarbon molecule; natural gas may also contain some heavier hydrocarbon molecules such as ethane (C2H6), propane (C3H8) and butane (C4H10), and Some acid gases, such as carbon dioxide and hydrogen sulfide; some natural gas produced by natural gas fields also contain organic sulfur such as carbon disulfide and carbonyl sulfide; organic sulfur compounds and hydrogen sulfide (H2S) are common impurities, and most of them should be used in the case of natural gas. Sulfide removal in natural gas, avoiding natural gas corrosion pipelines; although natural gas is colorless and odorless, it is sent to the final use Before, but also to add to the natural gas odorant with a thiol, to facilitate leak detection; carbon monoxide gas as in It is toxic, it is harmless to the human body in nature; but if the natural gas is in a high concentration state and the oxygen in the air is not enough to sustain life, it will still cause death; as a fuel, natural gas will also explode. Causes casualties; although natural gas is lighter than air and easily diverges, when natural gas is concentrated in a closed environment such as a house or tent, when a certain proportion is reached, a powerful explosion will be triggered; the explosion may level the entire house.
