Automatic Carbon Steel Foam Proportioning System 700L~13000L for Reliable Foam

A foam fire extinguishing system mainly consists of a fire pump, a fire water source, a foam extinguishing agent storage device, a foam proportioning device, a foam generating device, and pipelines. It works by mixing foam extinguishing agent and water in a specific ratio using a foam proportioner to create a foam mixture, which is then used by the foam generating device to form air foam before being applied to the burning object to extinguish the fire.

Foam fire extinguishing systems are classified into three types based on the foam expansion ratio: high, medium, and low expansion. There are also multiple options for the type of foam liquid.

Composed of hydrocarbon surfactant, fluorocarbon surfactant, desiccant, additive, polar film-forming agent, stabilizer, antifreeze, preservative, and other components. In addition to the performance of ordinary aqueous film-forming foam extinguishing agent to extinguish oil fires, this extinguishing agent can also quickly extinguish polar solvent fires such as alcohol, ketone, and aldehyde fires (a polar film-forming agent is added during production, forming a layer of gel film on the surface of polar flammable liquid to protect the foam from damage). It is a multi-functional foam extinguishing agent, widely used in key disaster prevention sites such as oil fields, refineries, oil depots, ships, large chemical plants, chemical fiber plants, petrochemical enterprises, chemical product warehouses, and solvent plants.

Also called light water foam extinguishing agent, composed of hydrocarbon surfactant, fluorocarbon surfactant, auxiliary agent, stabilizer, antifreeze, and other components. It is an efficient foam extinguishing agent characterized by forming a protective film on the surface of oil to inhibit oil evaporation. With the dual role of foam and protective film, it has high fire extinguishing efficiency, fast speed, good anti-reburning performance and sealing performance, high pollution resistance, and a long storage period. It can foam in various low and medium expansion foam generating equipment to put out oil fires; it can be used in combination with dry powder fire extinguishing agents to extinguish fires, and can also be used to extinguish large oil storage tank fires through "underwater spraying." Widely applicable to key disaster prevention sites such as oil fields, refineries, oil depots, ships, docks, airports, and hangars.

Also known as multifunctional fluoroprotein foam extinguishing agent, prepared by adding an appropriate amount of anti-alcohol agent and additives to fluoroprotein foam extinguishing agent. It not only has the function of fluoroprotein foam to extinguish oil fires but also has the ability of anti-soluble foam to extinguish alcohol fires. It can be used to extinguish oil fires as well as alcohol, ketone, aldehyde, and other flammable polar solvent fires. Widely applicable to key disaster prevention sites such as large petrochemical enterprises, chemical fiber plants, oil storage solvent plants, breweries, chemical product warehouses, ships, airports, oil extraction platforms, and storage and transportation terminals.

Prepared by adding appropriate fluorocarbon surfactant on the basis of protein foam extinguishing agent. Due to the function of fluorocarbon surfactant, the extinguishing agent has the extinguishing performance of protein foam extinguishing agent. The method of "underwater spraying" can also be used to put out the fire of large oil product storage tanks, or it can be combined with dry powder extinguishing agent, which is one third faster than protein foam extinguishing agent. Widely applicable to oil fields, oil depots, petrochemical enterprises, ships, airports, and units storing large amounts of oil products, used to extinguish large-scale oil fires.

The purpose of extinguishing fires is achieved through the covering, flooding, cooling, and suffocation effects of the foam layer:

1. Covering effect: The foam covering layer formed by fire-extinguishing foam on the surface of the burning object can isolate the surface of the burning object from the air.
2. Sealing effect: The foam layer seals the surface of the burning material, which can block the thermal radiation of the flame to the burning material, prevent the evaporation or thermal decomposition and volatilization of the burning material, and make it difficult for flammable gases to enter the combustion zone.
3. Cooling effect: The liquid folded from the foam has a cooling effect on the combustion surface.
4. Asphyxiation effect: The water vapor produced by the heating and evaporation of foam has the effect of diluting the oxygen concentration in the combustion zone.
