Gas-liquid proportioning mixed foam maker of compressed gas foam fire-fighting system

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 [0001] The invention relates to an equipment component of a foam fire extinguishing system, in particular to a gas-liquid ratio mixing foamer for a compressed gas foam fire extinguishing system. Background technique [0002] In recent years, with the rapid development of the economy and society, the fire situation has become more and more serious. There are more and more sudden fires in various occasions, and the scale of the fires is getting larger and larger, causing more and more losses. The traditional water and load Press type foam fire extinguishing device can't adapt to present fire situation more and more. Negative pressure foam fire extinguishing device is to inhale air through the negative pressure suction formed by spraying on the negative pressure foam spray gun, and form foam after gas and liquid are mixed for fire extinguishing. The foaming ratio is low and the foaming efficiency is low. Water, foam liquid The utilization rate is low, the waste...

[0002] In recent years, with the rapid development of the economy and society, the fire situation has become more and more serious. There are more and more sudden fires in various occasions, and the scale of the fires is getting larger and larger, causing more and more losses. The traditional water and load Compressed foam fire extinguishing devices are increasingly unable to adapt to the current fire situation

Negative pressure foam fire extinguishing device is to inhale air through the negative pressure suction formed by spraying on the negative pressure foam spray gun, and form foam after gas and liquid are mixed for fire extinguishing. The foaming ratio is low and the foaming efficiency is low. Water, foam liquid Low utilization rate, serious waste, high requirements for water source and power system required for fire extinguishing, and poor fire extinguishing effect

Traditional water and negative pressure foam fire extinguishing devices, in actual fire fighting, the hose filled with water or foam mixture is very heavy and cannot be moved to a very high position, and the height of the pressure is only tens of meters, which cannot be implemented in high-rise buildings, etc. high place fire fighting
