Abstract
The invention relates to an equipment part of a foam fire-fighting system, in particular to a gas-liquid proportioning mixed foam maker of a compressed gas foam fire-fighting system. The gas-liquid proportioning mixed foam maker of the compressed gas foam fire-fighting system comprises a shell and a mixed foaming chamber, wherein the mixed foaming chamber fully occupies the middle inside the shell; the input end of the mixed foaming chamber is communicated with a foam liquid inlet pipe and a gas chamber; the gas chamber is communicated with a compressed gas inlet pipe; the output end of the mixed foaming chamber is communicated with an output chamber; and an auxiliary mixed foaming medium is arranged in the mixed foaming chamber. In the gas-liquid proportioning mixed foam maker disclosed by the invention, the mixed foaming chamber is additionally arranged, and the auxiliary mixed foaming medium is arranged in the mixed foaming chamber, therefore, foaming multiples are increased, foaming efficiency reaches 100 percent and high utilization ratio of water and foam liquid and a good fire-fighting effect are achieved; output fire-fighting foams can be adhered to protected objects and have long drainage time and burn resistant time, and therefore, after-combustion is effectively prevented; and the output fire-fighting foams have light weight so that a water hose filled with the fire-fighting foams is very light, and the water hose can be moved to a very high position and easily and forcedly deliver the fire-fighting foams to a height more than 200 meters.
Description
Technical field
The present invention relates to a kind of froth fire extinguishing system part of appliance, particularly a kind of gas-liquid proportioning mixed foam maker of compressed gas foam fire-fighting system.
Background technology
In recent years, along with the high speed development of economic society, fire hazard situation is more and more severeer, the sudden fire of all kinds of occasions is more and more, fire scale is increasing, and the loss that causes is more and more higher, and traditional water and suction type fixed froth installation more and more can not adapt to present fire hazard situation.The suction type fixed froth installation, by spraying the negative-pressure sucking air amount that forms at the suction type foam lance, form foam after gas, liquid mix and be used for fire extinguishing, coefficient of foaming is low, foaming efficient is low, and water, foam solution utilization rate are low, and waste is serious, put out a fire required water source and dynamical system are required high, the fire extinguishing weak effect.Traditional water and suction type fixed froth installation, in fire extinguishing under battle conditions, the water band that is full of water or foam mixing liquid is very heavy, can't move to very high position, and presses high altitude to only have tens meters, can't implement the eminence fire extinguishing of high-rise building etc.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: a kind of defects that solved is provided, has improved coefficient of foaming and foaming efficient, strengthened the gas-liquid proportioning mixed foam maker of compressed gas foam fire-fighting system of fire extinguishing effect.
The technical solution adopted for the present invention to solve the technical problems is: gas-liquid proportioning mixed foam maker of compressed gas foam fire-fighting system, comprise housing, one end of housing is connected with foam solution inlet pipe and Compressed Gas inlet pipe, the other end is the output chamber, it is characterized in that: also comprise the mixed foaming chamber, the mixed foaming chamber takes the interior middle part of housing, the input of mixed foaming chamber is connected with foam solution inlet pipe and air chamber, wherein air chamber is inner walls, the space that foam solution inlet pipe outer wall and mixed foaming chamber surround, air chamber is connected with the Compressed Gas inlet pipe, the output of mixed foaming chamber is connected with the output chamber, and indoor being provided with of mixed foaming assisted the mixed foaming medium.
Described auxiliary mixed foaming medium can for undissolved little ball, be preferably fine ceramics ball or glass marble; Also can for corrosion-resistant net, be preferably stainless (steel) wire.
The two ends of described mixed foaming chamber are network structure, are preferably stainless (steel) wire.
The foam solution and the Compressed Gas that adopt network structure conveniently to input enter the mixed foaming chamber smoothly, and the fire foam of convenient output enters the output chamber, and when auxiliary mixed foaming medium is undissolved roundlet ball, adopt network structure can avoid little ball to spill from mixed foaming is indoor.
During use, Compressed Gas (air, nitrogen or inert gas) is pressed into foam liquid tank, it is indoor that foam solution is pressed into mixed foaming by the foam solution inlet pipe, a certain proportion of Compressed Gas (air, nitrogen or inert gas) is by the Compressed Gas inlet pipe simultaneously, enter the mixed foaming chamber through behind the air chamber, foam solution and Compressed Gas are at the indoor abundant mixed foaming of mixed foaming, produce the fire foam of extinguishing property the best, finally with the malleation form, by the output of output chamber, implement fire extinguishing from spray gun or shower nozzle ejection.
The beneficial effect that the present invention has is: the present invention is by setting up the mixed foaming chamber, and auxiliary mixed foaming medium is set mixed foaming is indoor, increased coefficient of foaming, and foaming efficient has reached absolutely, and water, foam solution utilization rate are high, good extinguishing effect; The fire foam of output can stick on the protected object, analyses liquid, anti-burning time long, can effectively prevent resume combustion; The fire foam quality of output is light, so that it is very light to be full of the water band of fire foam, can with the water Tape movement to very high position, can easily fire foam be sent to the height more than 200 meters.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, housing; 2, foam solution inlet pipe; 3, Compressed Gas inlet pipe; 4, output chamber; 5, mixed foaming chamber; 6, air chamber; 7, fine ceramics ball; 8, stainless (steel) wire.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further:
As shown in Figure 1, one end of housing 1 is connected with foam solution inlet pipe 2 and Compressed Gas inlet pipe 3, the other end is output chamber 4, mixed foaming chamber 5 takes the interior middle part of housing 1, the input of mixed foaming chamber 5 is connected with foam solution inlet pipe 2 and air chamber 6, wherein air chamber 6 is the space that housing 1 inwall, foam solution inlet pipe 2 outer walls and mixed foaming chamber 5 surround, air chamber 6 is connected with Compressed Gas inlet pipe 3, the output of mixed foaming chamber 5 is connected with output chamber 4, be full of fine ceramics ball 7 in the mixed foaming chamber 5, the two ends of mixed foaming chamber 5 are for being stainless (steel) wire 8.
During use, Compressed Gas is pressed into foam liquid tank, foam solution is pressed in the mixed foaming chamber 5 by foam solution inlet pipe 2, simultaneously the Compressed Gas of certain proportion (Compressed Gas with foam solution volume than 2: 1～6: 1) passes through Compressed Gas inlet pipe 3, enter mixed foaming chamber 5 through behind the air chamber 6, foam solution and Compressed Gas be 5 interior abundant mixed foamings in the mixed foaming chamber, produce the fire foam of extinguishing property the best, finally with the malleation form, export fire hose to by output chamber 4, implement fire extinguishing from spray gun or shower nozzle ejection.
