Description
Technical Field
The invention relates to the technical field of fire fighting equipment manufacturing, in particular to an automatic filling system of a carbon dioxide hydrate fire extinguisher.
Background
The fire extinguisher is a portable fire-fighting product, and chemical articles are placed in the fire extinguisher for rescuing and extinguishing fire. The fire extinguishing cylinders of different types are filled with different components, and generally can be divided into the following components according to different fire extinguishing agents: dry powder extinguishers, carbon dioxide extinguishers, water-based extinguishers, class D extinguishers, foam extinguishers and the like. The ABC dry powder fire extinguisher can effectively extinguish most of solid, liquid, gas and live equipment fires, is suitable for home equipment, factory workshops, office buildings, rental houses and the like, but the dry powder fire extinguisher has a large number of fire extinguishing agent dust particles and is not suitable for places with requirements on dust prevention. The carbon dioxide fire extinguisher is suitable for liquid and gas fire disasters, but cannot be used for extinguishing solid fire disasters, and is suitable for valuable libraries, dust-free workshops, machine rooms, equipment rooms and power distribution rooms. The water-based fire extinguisher is suitable for solid and liquid fires, but is not suitable for electrified fires. The metal D-shaped fire extinguisher is suitable for metal fires and can effectively control active metal fires. The water machine foam fire extinguisher is used for solid and liquid fire, and can extinguish gasoline fire and laboratory fire. The carbon dioxide hydrate is a non-stoichiometric enveloped cage-shaped compound generated by carbon dioxide gas and water under the conditions of high pressure and low temperature, and gas molecules are wrapped in a cage-shaped lattice formed by water molecules. The carbon dioxide hydrate can be decomposed under other conditions such as thermal stimulation, reduced pressure and the like, the decomposition process of the hydrate can absorb heat severely, the decomposition enthalpy is about 500kJ/kg, and 176 volumes of carbon dioxide and 0.8 volume of water can be stored per unit volume of the carbon dioxide hydrate under the standard condition. Due to its special physicochemical properties, carbon dioxide hydrate is receiving increasing attention from researchers in the field related to fire fighting equipment. When the carbon dioxide hydrate decomposes and absorbs part of heat around, the decomposition product carbon dioxide gas can be exhausted to surround the surface of a combustion object, the oxygen concentration around the combustible object is reduced to a certain degree, a suffocation effect is generated to extinguish a fire, and the other decomposition product water can also block flames to play a role in extinguishing the fire.
In summary, the research on the fire extinguisher with the hydrate is being deepened gradually due to the characteristics that the carbon dioxide hydrate absorbs heat and cools down and releases carbon dioxide and water, but the problem of how to fill the fire extinguisher with the carbon dioxide hydrate is puzzling the relevant researchers due to the characteristics that the carbon dioxide hydrate is harsh in transportation conditions, is very easy to decompose under normal temperature and normal pressure, and the like.
