Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing agent production equipment, in particular to a quantitative feeding mechanism. Background Art

[0002] Soluble water-based film-forming foam fire extinguishing agent AFFF / AR (also known as light water anti-soluble foam fire extinguishing agent) is prepared from composite surfactants, cosolvents, polar film-forming agents, stabilizers, antifreeze agents, preservatives, etc. In addition to the performance of general water-based film-forming foam fire extinguishing agents in extinguishing oil fires, the fire extinguishing agent also has the ability to extinguish polar (water-soluble) flammable solvent fires such as alcohols, esters, ethers, ketones, and aldehydes because the polar film-forming agent added to the formula can make the fire extinguishing agent form a gel film on the surface of polar flammable liquids to protect the fire extinguishing foam from being destroyed. It is a multifunctional fire extinguishing agent. The multifunctional fire extinguishing agent can be obtained by mixing with water in a ratio of 3:97 or 6:94 through low-multiplicity foam generating equipment. It is widely used in the fire fighting and prevention of petrochemical enterprises such as oil fields, oil depots, and refineries, chemical enterprises such as large chemical plants, chemical fiber plants, solvent plants, and ships, docks, and chemical product warehouses. The traditional preparation method is to add surfactants to various materials and mix them. The addition of different materials is different, and generally they need to be manually weighed before adding. However, this working method is relatively cumbersome and complicated, inconvenient to use, and affects the production rate of soluble water-based film-forming foam fire extinguishing agents.
