Embodiment Construction

[0020] The invention provides a premixed high-expansion foam generating device, which includes a high-expansion foam generator, a high-expansion foam premix pressure tank and a compressed gas cylinder, and a premixed foam liquid is housed in the high-expansion foam premix pressure tank, through The high-pressure gas in the compressed gas cylinder makes the premixed foam liquid enter into the high-expansion foam generator to generate high-expansion foam.

[0021] The premixed high-expansion foam generating device also includes an air inlet pipe, a pressure reducing valve, a safety valve, a pressure gauge, a filter, a first switch valve, a liquid outlet pipe, a second switch valve, a flushing liquid discharge pipe and a fire hose .

[0022] A safety valve, a pressure gauge, a filter, a first switch valve, a liquid outlet pipe, and a flushing and draining pipe are installed on the high-expansion foam premixing pressure tank, and the flushing and draining pipes are installed at th...

Abstract

The invention provides a pre-mixing type high-expansion foam generation device. The device comprises a high-expansion foam generator, a high-expansion foam pre-mixing pressure tank and a compression gas bottle; pre-mixing foam liquid is contained in the high-expansion foam pre-mixing pressure tank, and enters the high-expansion foam generator through high-pressure gas in the compression gas bottle, and high-expansion foam is generated; and under the condition that the exterior does not have water and electricity, a large amount of high-expansion foam can be rapidly and efficiently generated, and released to a liquefied natural gas leakage area, and liquefied natural gas diffusion and fire danger are effectively controlled.

Description

technical field [0001] The invention relates to the technical field of fire protection utilization, in particular to a premixed high-expansion foam generating device. Background technique [0002] In recent years, with the rapid development of the liquefied natural gas industry, fire accidents caused by the leakage and diffusion of liquefied natural gas have also occurred frequently. At present, there are two main control measures for LNG leakage and diffusion fire accidents: (1) Use fire water to dilute the concentration of LNG vapor and control the surrounding ignition sources; (2) Use fixed high-expansion foam generating devices, such as LNG Receiving station tank area, etc. These two measures all have very big dependence on (fire-fighting) water, especially adopt fire-fighting water, will consume a large amount of water resources, and existing high-expansion foam generating device needs to have the water with certain pressure to produce high-expansion foam , it will be...
