High Capacity Foam Bladder Tank - Professional Fire Suppression System Equipment for Industrial Plant Safety

Foam fire suppression system​

Description:
  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.

Product details and specifications:
 

Working principle: When the pressure water of the water supply pump enters the proportional mixer from the inlet pipe and valve, most of the water enters the main pipe and the proportional mixer throttling device. According to the principle of fluid mechanics, a section of low pressure zone is formed behind the throttling device, and a small part of the water enters the inlet pipe and flows into the storage tank, squeezing the diaphragm. Under the pressure of the pressure water, the extinguishing agent in the bag enters the low pressure zone of the proportional mixer through the outlet pipe and the outlet valve, so that the water and extinguishing agent are automatically mixed in proportion to form a foam mixture, which is sent to the foam generator and the spraying equipment through the pipeline for extinguishing. In many practical engineering applications, the design requires that electric ball valves should be installed on the water inlet pipe and liquid outlet pipe of the foam tank, and the field control cabinet should be equipped. The control principle is as follows: Principle of fire automatic control: When the on-site control cabinet is set to automatic mode, when the fire signal arrives, the inlet electric ball valve and outlet electric ball valve (220V) on the storage tank will be automatically opened; When the fire signal disappears, the inlet valve and outlet valve are automatically closed. There is a working status indicator light on the control cabinet (closed/open), and the valve feedback point on the control cabinet is the active point (220V), If passive feedback contacts are required, they should be specified in the procurement requirements. When manually controlling, the on-site control cabinet must be set to manual mode, and the corresponding valve opening and closing buttons on the control cabinet should sequentially open/close the inlet electric ball valve and the outlet electric ball valve. In case of power shortage in the on-site control cabinet, the valve opening wrench equipped on the electric valve can be used to manually open the electric valve

Foam liquid Types:
   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

Soluble water film forming foam extinguishing agent (AFFF/AR-3%, AFFF/AR-6%)	Aqueous film-forming foam(AFFF-3%,AFFF-6%)	Soluble fluoroprotein foam extinguishing agent (FP/AR-3%, FP/AR-6%)	Fluoroprotein foam extinguishing agent (FP-6% FP-3%)
Soluble water-resistant film-forming foam extinguishing agent is composed of hydrocarbon surfactant, fluorocarbon surfactant, desiccant, additive, polar film-forming agent, stabilizer, antifreeze, preservative, etc. 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 alcoho, ketone and aldehyde (polar film forming agent is added in the production process, 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, solvent plants, etc.	Aqueous film-forming foam extinguishing agent (also called light water foam extinguishing agent) is composed of hydrocarbon surfactant, fluorocarbon surfactant, auxiliary agent, stabilizer, antifreeze, etc. It is an efficient foam extinguishing agent. It is 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 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, hangars, etc	Soluble fluoroprotein foam extinguishing agent (also known as multifunctional fluoroprotein foam extinguishing agent) is 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, storage and transportation terminals, etc	Fluoroprotein foam extinguishing agent is 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 main fire extinguishing mechanism of foam systems:
  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.
