Fire fighting truck with multiple sets of fire extinguishing agents used in combination

Abstract

The invention discloses a fire fighting truck with multiple sets of fire extinguishing agents used in combination. The fire fighting truck with the multiple sets of fire extinguishing agents used in combination comprises a truck body, an auxiliary frame, a carriage, a containing tank, a mixing reactor, foam proportioning mixers and a pipeline, wherein the mixing reactor is a double-bag-pipe mixing reactor, the containing tank is composed of a water tank, a fire extinguishing agent A tank and a fire extinguishing agent B tank, the foam proportioning mixers comprise an A proportioning mixer and a B proportioning mixer, a fire extinguishing agent A enters a water inlet pipe of a fire pump through the A proportioning mixer, a water outlet pipe of the fire pump is connected with a water inlet of the double-bag-pipe mixing reactor, a fire extinguishing agent B is injected into a water outlet pipe of the double-bag-pipe mixing reactor through the B proportioning mixer, and the rear end of the water outlet pipe of the double-bag-pipe mixing reactor is connected with a mixing unit. According to the fire fighting truck with the multiple sets of fire extinguishing agents used in combination, an on-site mixing reaction for combined use of the multiple fire extinguishing agents is achieved through the double-bag-pipe mixing reactor, the proportioning mixers and the pipeline, and a compound high-stability foam fire extinguishing agent formed after the mixing reaction is durable, stable, long in anti-burning time and capable of rapidly extinguishing fires and efficiently controlling the fires.

Description

technical field [0001] The invention relates to a fire truck in which multiple groups of fire extinguishing agents are used in combination. Background technique [0002] Fire trucks are special vehicles mainly used to perform fire response tasks, and are also used by fire departments in most countries, including China, for other emergency rescue purposes. Fire trucks can transport firefighters to the scene of disasters and provide them with a variety of tools for disaster relief tasks. Common types of fire trucks include water tank fire trucks, foam fire trucks, pump fire trucks, climbing platform fire trucks, ladder fire trucks, etc. At present, there are fire extinguishing agents that can be used in multiple groups, such as 2019113522657 (a solid-liquid two-component foam fire extinguishing agent) or 2019113530352 (a general-purpose high-stable foam fire extinguishing agent), which are produced by mixing multiple groups of fire extinguishing agents with water. Foam, then...

AI Technical Summary

Problems solved by technology

When the existing fire trucks use this fire extinguishing agent that can be used in multiple groups, due to the short mixing time of the fire extinguishing agent and water, an efficient fire extinguishing cover cannot be formed, and its fire extinguishing efficiency and burn resistance time need to be improved
