Pressure-storage premix type water mist foam fire extinguishing apparatus for ships

Abstract

The invention relates to a pressure-storage premix type water mist foam fire extinguishing apparatus for ships, comprising a high-pressure tank, a storage tank, a flexible pipe, a bobbin disc and a water mist foam spray head, wherein the inner side of the top of the storage tank is provided with a foam raw liquor bottle; the foam raw liquor bottle is communicated with a high-pressure gas inlet; the high-pressure gas inlet is connected with the high-pressure tank by a high-pressure gas pipe; the outlet of the bottom of the foam raw liquor bottle is provided with a three-way valve; the downward outlet of the three-way valve is communicated with a foam raw liquor spray head by a pipe fitting; water is filled in the storage tank; the water level is arranged at the position of an overflow gap; the spray head is arranged below the liquid level in the storage tank; the rightward outlet of the three-way valve is arranged above the liquid level in the storage tank; the rightward outlet of the three-way valve is communicated with a regulating valve by the pipe fitting. The invention has compact structure, small volume and high fire extinguishing efficiency and is conveniently rapidly shifted on the ships for put out fire in initial stage and larger fire in time; foam raw liquor is sprayed to water by 360 degrees by adopting double foam raw liquor spray heads, and secondary stirring mixing is carried out on mixed liquid by subsequently sprayed high-pressure gas; matching is accurate, and mixing is evener.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting facilities, and in particular relates to a novel high-efficiency marine pressure storage premixed fine water mist foam fire extinguishing device. Background technique [0002] At present, there is no fast, efficient and portable fire-fighting device in the marine fire-fighting system. Moreover, there are relatively many sudden fires in various areas on the ship, and the scale of the fires is also relatively large. Existing dry chemical, CO2, and medium-expansion foam systems can only extinguish early, small-scale fires. Although there are fixed fire-fighting systems (such as aqueous film-forming foam fire-extinguishing systems, etc.) The damage to the equipment is relatively large. Therefore, there is an urgent need for fire extinguishing devices that are flexible, portable, and highly efficient in extinguishing fires on board, and can quickly extinguish Class A, B, and C fires, especiall...

AI Technical Summary

Problems solved by technology

[0003] In view of the problems existing in the above-mentioned marine fire fighting system, in order to solve the early or larger fires of A, B, C and electrical equipment, especially for 20m 2 In order to solve the problems of Class B fires, the present invention provides a marine pressure storage premixed water mist foam fire extinguishing device with light structure and convenient and fast movement.
