Description

一种二氧化碳水合物灭火剂及其应用A kind of carbon dioxide hydrate fire extinguishing agent and its application

技术领域 technical field

本发明涉及一种灭火剂的制备方法,具体涉及一种水合物灭火剂及其应用。 The invention relates to a preparation method of a fire extinguishing agent, in particular to a hydrate fire extinguishing agent and its application.

背景技术 Background technique

二氧化碳水合物是由二氧化碳气体与水在高压低温条件下生成的一种非化学计量的包络状笼型化合物,气体分子被包裹在水分子形成的笼型晶格中。单位体积的水合物可以储存160~180体积标准状况下的气体。作为一种环境友好型的新型固化技术,二氧化碳水合物生成技术在海水淡化、污水处理、二氧化碳捕获以及置换开采天然气水合物等工业领域有着广泛的应用前景。 Carbon dioxide hydrate is a non-stoichiometric enveloping cage compound formed by carbon dioxide gas and water under high pressure and low temperature conditions. Gas molecules are wrapped in cage lattices formed by water molecules. A unit volume of hydrate can store 160-180 volumes of gas under standard conditions. As an environmentally friendly new solidification technology, carbon dioxide hydrate generation technology has broad application prospects in industrial fields such as seawater desalination, sewage treatment, carbon dioxide capture, and displacement mining of natural gas hydrate.

二氧化碳水合物生成的逆过程是一个剧烈吸热的分解过程,其分解焓约为500 kJ/kg,比冰的融化焓(333 kJ/kg)还大,同时水合物分解后释放出水和二氧化碳,二者都是传统的灭火材料。水能灭火的机理主要在于水的冷却作用,把燃烧物及其周围环境的温度降低至其着火点以下而熄灭火焰,但水的流动性很强,大部分水未发挥作用就流失了,隔绝燃烧物周围空气的作用不明显。传统的水系灭火剂是在水中加入吸水性颗粒、表面活性剂、增稠剂等添加剂以提高水的灭火性能,但其成本大大增加。二氧化碳灭火的机理主要在于二氧化碳能稀释可燃物周围的空气,产生窒息作用而熄灭火焰。传统的二氧化碳灭火剂使用的液态二氧化碳,被喷出时液体迅速气化吸热,除了起稀释空气的作用外,还可以降低燃烧物周围温度,但冷却起次要作用。二氧化碳灭火剂容易冻伤人或冻住把手,而且造价高,对设备要求严格。 The reverse process of carbon dioxide hydrate formation is a violent endothermic decomposition process, and its decomposition enthalpy is about 500 kJ/kg, which is larger than the melting enthalpy of ice (333 kJ/kg). At the same time, the hydrate releases water and carbon dioxide after decomposition. Both are traditional fire extinguishing materials. The mechanism of water energy fire extinguishing mainly lies in the cooling effect of water, which lowers the temperature of the burning object and its surrounding environment below its ignition point to extinguish the flame, but the fluidity of water is very strong, and most of the water is lost before it plays a role, and the combustion is isolated. The effect of the air around the object is not obvious. The traditional water-based fire extinguishing agent is to add water-absorbing particles, surfactants, thickeners and other additives to water to improve the fire-extinguishing performance of water, but its cost is greatly increased. The mechanism of carbon dioxide fire extinguishing mainly lies in the fact that carbon dioxide can dilute the air around combustibles, produce suffocation and extinguish the flame. The liquid carbon dioxide used in the traditional carbon dioxide fire extinguishing agent quickly vaporizes and absorbs heat when it is sprayed out. In addition to diluting the air, it can also reduce the surrounding temperature of the burning object, but the cooling plays a secondary role. Carbon dioxide fire extinguishing agent is easy to frostbite people or freeze the handle, and the cost is high, and the requirements for equipment are strict.

水系灭火剂流动性强导致灭火效率将低,而加入添加剂后又造成成本增加;二氧化碳灭火剂虽然灭火效率高,但对灭火设备要求严格,而且造价高。考虑到二氧化碳水合物分解吸热降温且释放二氧化碳和水的特点,现将其作为一种新型环保灭火材料予以提出。 The strong fluidity of water-based fire extinguishing agents will lead to low fire extinguishing efficiency, and the addition of additives will increase the cost; although carbon dioxide fire extinguishing agents have high fire extinguishing efficiency, they have strict requirements on fire extinguishing equipment and are expensive. Considering the characteristics of decomposing carbon dioxide hydrate to absorb heat and cool down and release carbon dioxide and water, it is now proposed as a new type of environmentally friendly fire extinguishing material.

发明内容 Contents of the invention

本发明的目的在于克服现有灭火剂效率低、成本高的缺点,提出一种新型环保灭火剂——二氧化碳水合物灭火剂,由二氧化碳气体与水在高压低温条件下生成,并在低温环境中研磨、筛分成一定粒径的结晶水合物粉末,其中二氧化碳分子被包裹在水分子构成的笼型晶格中。所述水合物灭火剂在灭火时,水合物粉末覆盖在可燃物表面,可减少可燃物与空气的接触,分解吸热可降低燃烧区温度,释放的二氧化碳稀释可燃物周围空气,释放的水也可以冷却并覆盖可燃物,从而达到灭火的目的。 The purpose of the present invention is to overcome the disadvantages of low efficiency and high cost of existing fire extinguishing agents, and propose a new type of environmentally friendly fire extinguishing agent - carbon dioxide hydrate fire extinguishing agent, which is produced by carbon dioxide gas and water under high pressure and low temperature conditions, and can be used in low temperature environment Grinding and sieving crystalline hydrate powder with a certain particle size, in which carbon dioxide molecules are wrapped in a cage lattice formed by water molecules. When the hydrate fire extinguishing agent is extinguishing a fire, the hydrate powder covers the surface of the combustibles, which can reduce the contact between the combustibles and the air, decomposes and absorbs heat to reduce the temperature of the combustion zone, and the released carbon dioxide dilutes the air around the combustibles, and the released water also It can cool and cover combustibles, so as to achieve the purpose of fire extinguishing.

本发明的技术原理: Technical principle of the present invention:

二氧化碳水合物灭火剂是由二氧化碳气体与水在高压低温条件下生成,并在低温环境中研磨、筛分成一定粒径的结晶水合物粉末,其中二氧化碳分子被包裹在水分子构成的笼型晶格中。该水合物灭火剂可由二氧化碳与水在高压搅拌反应釜中快速生成,也可由二氧化碳与干水或添加剂溶液在高压静态反应釜中快速生成。 Carbon dioxide hydrate fire extinguishing agent is produced by carbon dioxide gas and water under high pressure and low temperature conditions, and is ground and sieved into crystalline hydrate powder with a certain particle size in a low temperature environment, in which carbon dioxide molecules are wrapped in cage lattices composed of water molecules middle.

The fire extinguishing agent has both the advantages of the water-based fire extinguishing agent and the carbon dioxide fire extinguishing agent, and has characteristics that the two do not have.
