B-type air foam high-jet fire extinguishing device

Abstract

The invention provides a B-type air foam high-jet fire extinguishing device. The B-type air foam high-jet fire extinguishing device comprises carrier equipment, and a rotary table, a water system, a foam system, a screw type compressed air system, a lifting system and a fire monitor which are arranged on the carrier equipment, the water system, the foam system and the screw type compressed air system are respectively arranged on a carrier equipment chassis, the rotary table is arranged at the upper part of the carrier equipment, meanwhile, a lifting system is arranged on the rotary table, and a fire monitor is arranged at the tail end of the lifting system; wherein water in the water system and foam in the foam system are mixed at the position, conveyed to the lower portion of the rotary table, of a pipeline, and water-foam mixed liquid is formed; compressed air of the screw type compressed air system and water-foam mixed liquid are mixed at the position of a phase pipeline which is conveyed to the upper portion of the rotary table, and are sprayed out through the lifting system and the fire monitor. The invention has the advantages of large flow, long range and high fire extinguishing efficiency, can cover and extinguish fire from top to bottom, and meets the fire extinguishing requirements of large-scale petrochemical fires.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a Class B air foam high spray fire extinguishing device. Background technique [0002] The flammable and explosive substances involved in petrochemical enterprises are of many types and quantities, and the risk of fire is high. Once a fire breaks out, the burning speed is fast and the fire develops rapidly. It is easy to form a large-scale three-dimensional fire, and it is difficult to fight. [0003] At present, the fire-fighting equipment used to fight large-scale petrochemical fires mainly includes elevating jet fire trucks, Class B foam fire trucks and Class A foam fire trucks. Among them, regarding the high-lift jet fire truck: Although the application of the large-flow 10,000-liter pump has gradually increased the jet flow of the high-lift jet fire truck, and the large-flow remote water supply vehicle can also solve the problem of external water supply, but ...

AI Technical Summary

Problems solved by technology

Among them, regarding the high-lift jet fire truck: Although the application of the large-flow 10,000-liter pump has gradually increased the jet flow of the high-lift jet fire truck, and the large-flow remote water supply vehicle can also solve the problem of external water supply, but the existing high-flow jet fire The foam system of the car has a low foaming ratio, resulting in a large amount of foam for a single large-scale fire, and low fire extinguishing efficiency per unit of water

About Class B foam fire trucks: without lifting arms, the foam is not shot high enough to fully cover the fire point from top to bottom

About Class A foam fire truck: the flow rate is small, the shooting range is only 20-30m, and at the same time, the shooting height is insufficient due to the lack of lifting arms, resulting in a small fire extinguishing radius, which cannot meet the needs of large-scale fires

[0004] Accordingly, the current conventional fire-fighting equipment has poor fire extinguishing and anti-reburning effects when fighting large-scale petrochemical fires, and it is urgent to design a new type of fire extinguishing device
