High reliability self-ignition method of sodium in seawater

Abstract

The invention discloses a high-reliability self-ignition method of sodium in seawater, and belongs to the application field of water-based combustion related technologies based on seawater in a marineenvironment. The method can realize the self-ignition link of the technology, that is, no external energy is given in a process of technical application, and the fuel is ignited by own design to automatically burn. The reason for the high reliability self-ignition achieved by 'Na+NH4Cl' type raw material combination given by the invention lies in two aspects: one is to use the reaction of Na withseawater to release high-density reaction heat and to generate characteristics of inflammable gas H2, not only providing combustion energy, but also providing a certain amount of fuel; the second isto use the hydrolysis of NH4Cl to modify the weakly alkaline seawater to be strongly acidic, to aggravate the reaction degree between Na and seawater, and further improve the reliability. The method not only has high self-ignition reliability, but also can enhance a 'burning' effect of the technology, at the same time has two advantages of environmental friendliness and high cost effectiveness, and therefore undoubtedly has broad application prospects.

Description

technical field [0001] The invention relates to a highly reliable self-ignition method for sodium in seawater, which belongs to the technical application field of seawater-based water-based combustion in marine environments. Background technique [0002] Seawater-based combustion related technologies based on seawater (hereinafter referred to as offshore water-based combustion technology) refers to special materials based on special materials that react with seawater to form the fuel necessary for combustion, and use specific methods to spontaneously ignite Or a kind of technology that burns fuel by means of combustion. Among them, self-ignition means that no external energy is given during the process of technology realization, but relying on the design of the technology itself to ignite the fuel to make it burn automatically, and self-ignition means that no ignition link is added to the design of the technology itself. Rather, the fuel is ignited to burn by applying exter...

Problems solved by technology

For marine water-based combustion technology, due to the special application environment of seawater, its ignition means should not only meet the self-ignition requirements of the technology itself, but also be suitable for seawater environment. Therefore: (1) Due to the existence of a large amount of seawater , making it extremely difficult to ignite methods such as open flames and electric sparks; (2) Usually, the temperature of seawater is low, so the reliability of igniting methods such as high-temperature objects, impact and friction heat generation and heating is not high ; (3) To achieve adiabatic compression and heating at sea, light irradiation and focusing and other means of ignition often requires certain equipment, in order to achieve the purpose of self-ignition, the cost is relatively high

[0005] Obviously, due to various reasons such as difficulty in implementation and high cost, the first six categories of the above seven methods are not suitable
