Description
Technical field
The invention belongs to fire-fighting equipment technical field, particularly a kind of dress that air aqueous foam is prepared with pneumatic mode
Put.
Background technology
The development of foam fire extinguishing technique arises from the U.S. in the 10's of last century at first, then, with surface chemistry industry
Development, the research of foam fire extinguishing technique is also gradually paid attention to by domestic and international experts and scholars, and is developed rapidly.1949
Year, Brady is first public to report the characteristic research on aqueous foam.Into the fifties in last century, Britain, the former Soviet Union, original
The states such as West Germany, Japan have carried out the research work of this respect in succession, achieve certain achievement, and, Jacobi etc. in 1956
The first public aqueous foam that reports of people is applied to fire practice.60th, the mid-1970s U.S., the former Soviet Union, Poland, Japan
Deng successfully have developed high magnification numbe foaming agent.The eighties, United States Bureau of Mines etc. have developed compressed air foam system, and carry out
Downhole powder dust and fire test, achieve preferable application effect.The nineties, Rick and Wes accelerate foam technology to should
With the R＆D work of product, product was formed in 2002, the same year and by the fire department of production marketing to the Kentucky State, Yi Jiyong
Prevented and treated in the fire of Nigeria's offshore oil field operation and Louisiana oil field operation.Into after 21 century, researchers master
The study on the modification to foam is concentrated on, to improve fire-fighting efficiency and effect.
The fire-fighting problem Journal of Sex Research work of China is started late, and the initial development stage is just entered until the end of the seventies.In recent years
Come, either kind, production technology and production capacity grew a lot China's fire foam, from Ministry of Public Security Tianjin in 1979
Fire Research Station is developed first generation aqueous film-forming foam extinguishing agent and is started, and China's fire foam technology has rapid development.
Fire foam species is enriched constantly, most widely used including eggwhite type foam extinguishing chemical, synthesis type fire foam.Into
21 century, occur in that with compressed-air foam, heptafluoro-propane gas bubble extinguishing chemical and three-phase foam extinguishing agent etc. as representative
Novel foam extinguishing agent and related application technology.
The current Preliminary Applications of aqueous foam technology are in fire prevention and control field, and the purpose higher to reach fire protection efficiency,
Domestic and foreign scholars extensive concern focuses on the little of foam preparation facilities research in the research of foam solution and its additive.Water
Property foam technology is developed so far from the fifties, and the foam preparation facilities of industrial applications is broadly divided into three power and double dynamical system
System.Three dynamical systems mainly use injection type foam pattern：Water is added as active force using water pump, screw pump adds foaming agent,
Gas is added as secondary power using air compressor machine.Double dynamical bubble system processed is broadly divided into two classes：One is net formula foam pattern.Using sky
Be sprayed onto expanding foam solution on foam screen by water pump as active force by press, is foamed；Two is injection type foam pattern.Profit
With water pump as active force, the negative pressure produced by Venturi tube is sucked in foam maker foaming agent, and using air compressor machine as secondary
Power adds gas, is foamed.Three dynamical systems easily realize quantitative control, but system dynamic source is excessive, use inconvenience, peace
Full hidden danger is larger.The foam scale of construction that net formula foam pattern in hybrid power system is produced is excessive, and foam is short of power, and foam screen
It is fragile.Injection type foam pattern hydraulic pressure in hybrid power system is higher, and technique is more complicated and is difficult to quantitative addition foam
Agent.Nearest useful high-pressure pump is reported as the experimental study of the aqueous foam preparation facilities of single-power:Injected water into high-pressure pump
Venturi tube, by venturi throat produce negative pressure suck foam solution and air prepare foam, but hydraulic demand 10MPa with
On.
Air aqueous foam technology serves positive role when fire is prevented and treated, but due to being moved using three more than its preparation facilities
Power is double dynamical, complex process, and maintenance test process is more lengthy and tedious, at the same carry out at the scene using when more have inconvenience, it is difficult to push away
The universalness application of dynamic foam technology.
For the technical problem, be by air aqueous foam technology it is simpler, be easily applied to fire preventing and treating, having must
Develop a kind of device that air aqueous foam is prepared with pneumatic mode.
